Subject: [PATCH 01/15] Lay v1 foundations: README/docs-first Trust & Safety
 rewrite
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reframes moderate from a profanity validator (0.1) into a full Trust & Safety gem: report/block/filter/moderate + DSA / App Store / Play compliance. This is the docs-first pass — README, docs/, adaptive install migration, initializer, Gemfile/Appraisals/CI/SimpleCov coherence with the ecosystem. Gem code (models/services/concerns/filters) follows next.

-# 👮‍♂️ `moderate` - Block profanities in text fields
+# 🛡️ `moderate` - Trust & Safety for your Rails app (report, block, filter, comply)
 
-`moderate` is a Ruby gem that moderates user-generated text content by adding a simple validation to block bad words in any text field (profanities, cussing, swearing, obscenity, etc.)
+[![Gem Version](https://badge.fury.io/rb/moderate.svg)](https://badge.fury.io/rb/moderate) [![Build Status](https://github.com/rameerez/moderate/workflows/Tests/badge.svg)](https://github.com/rameerez/moderate/actions)
 
-Simply add this to your model:
+> [!TIP]
+> **🚀 Ship your next Rails app 10x faster!** I've built **[RailsFast](https://railsfast.com/?ref=moderate)**, a production-ready Rails boilerplate template that comes with everything you need to launch a software business in days, not weeks. Go [check it out](https://railsfast.com/?ref=moderate)!
+
+`moderate` gives your Rails app a complete **Trust & Safety** layer — let users **report** abusive content, **block** each other, **filter** objectionable text and images before they're posted, and run a **moderation queue** your admins actually use. It ships **DSA-compliant** (EU Digital Services Act) and aligned with the **Apple App Store** and **Google Play** review guidelines for user-generated content, so you stop leaving store approvals and legal exposure to chance.
+
+It reads like plain English. Make any model reportable:
+
+```ruby
+class Comment < ApplicationRecord
+  reportable
+end
+```
+
+Let any user block another:
 
 ```ruby
-validates :text_field, moderate: true
+current_user.block!(@other_user)
+current_user.blocks?(@other_user)   # => true
 ```
 
-That's it! You're done. `moderate` will work seamlessly with your existing validations and error messages.
+Filter content before it's ever saved — one line:
+
+```ruby
+class Message < ApplicationRecord
+  moderates :body            # blocks profanity/slurs/threats by default; or :flag for review
+end
+```
+
+And give admins a real queue to act on:
+
+```ruby
+Moderate::Report.pending           # everything awaiting a decision
+report.resolve!(by: current_user, remove_content: true, ban_user: true, note: "Hate speech")
+```
+
+That's the whole idea: **the messy, legally-loaded plumbing every social/UGC app needs — report, block, filter, moderate, appeal, comply — as one coherent, Ruby-esque gem** instead of scattered, half-finished, store-rejecting DIY code.
+
+> [!NOTE]
+> `moderate` is **UI-agnostic by design**: most Trust & Safety lives in *admin* surfaces, so the gem ships the **primitives** (models, services, helpers, controller concerns) and lets you **bring your own UI**. It plugs into [`madmin`](https://github.com/excid3/madmin) (or any admin) in minutes — see [Admin & moderation queue](#-admin--the-moderation-queue). It also snaps into the rest of the ecosystem: [`goodmail`](https://github.com/rameerez/goodmail) for decision emails, [`telegrama`](https://github.com/rameerez/telegrama) for admin alerts, and [`noticed`](https://github.com/excid3/noticed) for multi-channel notifications — all through one `notify` hook.
+
+---
+
+## Why this gem exists
 
-> [!WARNING]
-> This gem is under development. It currently only supports a limited set of English profanity words. Word matching is very basic now, and it may be prone to false positives, and false negatives. I use it for very simple things like preventing new submissions if they contain bad words, but the gem can be improved for more complex use cases and sophisticated matching and content moderation. Please consider contributing if you can improve the gem, or have good ideas for additional features.
+Every app with user-generated content eventually faces the same wall. A user posts something vile, another user wants them gone, Apple rejects your build for "no way to report objectionable content," and a Spanish lawyer emails you about the Digital Services Act. So you start bolting on a `reports` table, a `blocks` table, a profanity regex, an admin page, a "notify the reporter" email… and it's suddenly a sprawling, half-correct subsystem entangled with your core app.
 
-# Why
+It's the kind of plumbing nobody wants to build, everybody rebuilds, and almost everybody ships *incomplete* — which is exactly what gets apps rejected from the stores and exposed under the DSA. `moderate` is the single, opinionated, batteries-included source of truth for it:
 
-Any text field where users can input text may be a place where bad words can be used. This gem blocks records from being created if they contain bad words, profanity, naughty / obscene words, etc.
+- **Report** users and content (in-app), with evidence snapshots and a real decision workflow.
+- **Block** users (bidirectional), enforced everywhere a blocked pair could reconnect.
+- **Filter** text and images before they're posted (`:off` / `:block` / `:flag`), with pluggable backends — a built-in offline wordlist and OpenAI's free multimodal moderation, or your own.
+- **Moderate** from a queue: remove content, ban users, dismiss, all audited.
+- **Comply**: DSA notice-and-action (Art. 16), statement of reasons (Art. 17), internal appeals (Art. 20), transparency counters (Art. 24); Apple Guideline 1.2 and Google Play UGC requirements.
 
-It's good for Rails applications where you need to maintain a clean and respectful environment in comments, posts, or any other user input.
+It works standalone, and gets better with the rest of the ecosystem.
 
-# How
+## What `moderate` does and doesn't do
 
-`moderate` currently downloads a list of ~1k English profanity words from the [google-profanity-words](https://github.com/coffee-and-fun/google-profanity-words) repository and caches it in your Rails app's tmp directory.
+**Does:**
+- User & content **reporting** (in-app) + a public **DSA legal-notice** intake form.
+- **Blocking** with a single source-of-truth query you enforce in search, messaging, profiles, anywhere.
+- **Pre-publication content filtering** with three modes and pluggable adapters (text, image, LLM).
+- A **moderation queue** with audited resolve / dismiss / remove-content / ban actions.
+- **Appeals**, **statement-of-reasons** notifications, and **transparency** aggregation for the DSA.
+- Optional **audit** and **notification** hooks that fan out to your mailer / admin alerts / push.
 
-## Installation
+**Doesn't** (on purpose — these are other tools' jobs):
+- Authentication / current-user (that's Devise — you tell `moderate` your user class).
+- Sending the actual emails/push (that's [`goodmail`](https://github.com/rameerez/goodmail) / [`noticed`](https://github.com/excid3/noticed) — `moderate` just emits events).
+- The admin UI chrome (that's [`madmin`](https://github.com/excid3/madmin) / your app — `moderate` gives you the data + primitives).
+- A bulletproof ML classifier out of the box (the default text filter is a fast, multilingual wordlist; bring an LLM/image adapter when you want one).
 
-Add this line to your application's Gemfile:
+---
+
+## Quickstart
+
+Add the gem:
 
 ```ruby
-gem 'moderate'
+gem "moderate"
 ```
 
-And then execute:
+Install it (creates the migration + an initializer):
 
 ```bash
 bundle install
+rails generate moderate:install
+rails db:migrate
 ```
 
-Then, just add the `moderate` validation to any model with a text field:
+Tell `moderate` who your users are, and make a model reportable:
 
 ```ruby
-validates :text_field, moderate: true
+# config/initializers/moderate.rb
+Moderate.configure do |config|
+  config.user_class = "User"
+end
+```
+
+```ruby
+class User < ApplicationRecord
+  has_moderation     # can report, block, be blocked, be banned
+end
+
+class Message < ApplicationRecord
+  reportable         # can be reported
+  moderates :body    # …and filtered before it's saved
+end
 ```
 
-`moderate` will raise an error if a bad word is found in the text field, preventing the record from being saved.
+That's it — you now have reporting, blocking, filtering, and a moderation queue. Everything below is detail.
+
+---
 
-It works seamlessly with your existing validations and error messages.
+## 🧑‍🤝‍🧑 Actors: report & block
 
-## Configuration
+Add `has_moderation` to your user model (or any model that acts on behalf of a person) — it sits right alongside your other ecosystem macros like `has_credits` / `has_wallets`:
+
+```ruby
+class User < ApplicationRecord
+  has_moderation
+end
+```
+
+*(Prefer an explicit include? `include Moderate::Actor` is the exact equivalent — the macro just lazily includes it.)*
+
+**Blocking** is a bidirectional safety edge — once either side blocks, neither should see or reach the other:
+
+```ruby
+current_user.block!(@other)     # idempotent; audited; fires your on_block hook
+current_user.unblock!(@other)
+current_user.blocks?(@other)    # I blocked them
+current_user.blocked_by?(@other)
+current_user.blocked_with?(@other)   # either direction — the one you check in features
+```
+
+Enforce it anywhere with the single source-of-truth query (no hand-rolled block SQL ever again):
+
+```ruby
+# Hide blocked people from a marketplace / search / inbox:
+Post.where.not(user_id: Moderate.blocked_ids_for(current_user))
+```
+
+**Reporting** content or a person:
+
+```ruby
+current_user.report!(@message, category: :harassment, details: "Won't stop messaging me")
+current_user.report!(@user,    category: :impersonation)
+```
+
+`moderate` snapshots the offending content at report time (so evidence survives edits/deletes), infers who's responsible, sends the reporter a receipt, and drops it in the queue.
+
+## 🚩 Reportable content
+
+Declare what can be reported with one `reportable` line — the fields are optional (omit them to report the whole record):
+
+```ruby
+class Listing < ApplicationRecord
+  reportable :title, :description
+
+  # Tell moderate how to present & clean this content when a moderator acts:
+  def moderation_label = "Listing #{id}"
+  def reported_owner   = user                # who's responsible (defaults sensibly)
+end
+```
+
+*(Explicit-include equivalent: `include Moderate::Reportable` + `reportable_fields :title, :description`.)*
+
+You get:
+
+```ruby
+listing.reports          # reports filed against this record
+listing.reported?        # any open report?
+listing.flagged?         # any pending system (auto-filter) flag?
+```
+
+Drop a report link into any view with the helper (it renders nothing if the viewer can't report the content):
+
+```erb
+<%= moderate_report_link(@listing, field: :description) %>
+```
+
+Adding a new reportable type is one `reportable` line — the intake, queue, snapshot, and admin code never change.
+
+## 🧪 Content filtering: `:off` / `:block` / `:flag`
+
+Filtering is one declaration per field, with three modes:
+
+```ruby
+class Message < ApplicationRecord
+  moderates :body                       # uses the default mode (see config)
+end
+
+class Profile < ApplicationRecord
+  moderates :bio,    mode: :block       # reject the save if it trips the filter
+  moderates :avatar, mode: :flag, with: :image   # allow the save, queue it for review
+end
+```
+
+- **`:off`** — no check.
+- **`:block`** — the write is rejected with a validation error (great for public, high-trust fields).
+- **`:flag`** — the write **succeeds**, and a `Moderate::Flag` is created **after commit** for human or automated review (great for DMs, where you don't want to block mid-conversation).
+
+Why this matters: `:flag` never lives in a validator (validators must be side-effect-free, and a flag created inside a rolled-back transaction would silently vanish) — `moderate` handles that correctly for you.
+
+Check content directly anywhere:
+
+```ruby
+result = Moderate.classify("some sketchy text")
+result.allowed?    # => false
+result.categories  # => [:hate, :"hate/threatening"]
+result.scores      # => { "hate" => 0.97, "hate/threatening" => 0.81 }   (0..1 for service adapters)
+result.labels      # => [#<Label category: :hate, subcategory: :threatening, score: 0.81, input: :text>, …]
+```
+
+### Filter adapters (wordlist, OpenAI, your own — one interface)
+
+Every backend implements the same tiny contract — `classify(value) → Moderate::Result` — so they're interchangeable per field:
+
+| Adapter | Use it for | Notes |
+| --- | --- | --- |
+| `:wordlist` (default) | text | Fast, multilingual, offline, zero-dependency. Unicode + leetspeak + spacing-evasion resistant. Ships `en`/`es` lists; add your own. |
+| `:openai` | **text *and* image** | OpenAI `omni-moderation-latest` — **free**, multimodal, returns the canonical labels + `0..1` scores + which input (text/image) tripped each. Runs **async** (`Moderate::ClassifyJob`) in `:flag` mode. The recommended "real" adapter. |
+| *your own* | anything | `register_adapter(:rekognition, …)` / `:replicate` / Perspective / a self-hosted model — any object responding to `classify`. No built-in pretends the backend must be an "LLM". |
+
+All adapters map their provider labels onto **one canonical taxonomy** (OpenAI's: `harassment[/threatening]`, `hate[/threatening]`, `sexual[/minors]`, `self-harm[/intent|/instructions]`, `violence[/graphic]`, `illicit[/violent]`), so `Moderate::Flag`, the DSA statement of reasons, and the transparency counters all speak one vocabulary.
+
+```ruby
+Moderate.configure do |config|
+  config.default_filter_mode = :block
+  config.filter_adapter      = :wordlist
+  config.filter "Message", :body,   with: :wordlist, mode: :flag
+  config.filter "Profile", :avatar, with: :openai,   mode: :flag   # one adapter moderates text AND images
+end
+```
+
+> **`:block` requires a synchronous adapter** (`:wordlist`) — you can't reject a save on a background result. Service adapters like `:openai` run in `:flag` mode (allow the write, classify in a job, file a `Moderate::Flag`). `moderate` validates this for you and says so.
+
+Bring your own adapter — it's just an object that responds to `classify`:
+
+```ruby
+class MyAdapter
+  def classify(value) = Moderate::Result.new(allowed: ..., categories: [...], scores: {...})
+end
+Moderate.register_adapter(:my_adapter, MyAdapter.new)
+```
+
+> The original `moderate` (≤ 0.1) was *only* a profanity validator. That `validates :field, moderate: true` one-liner still works — it's now the `:wordlist` adapter in `:block` mode. See [Upgrading from 0.x](#upgrading-from-0x).
+
+## 🛠️ Admin & the moderation queue
+
+Most of Trust & Safety happens in admin. `moderate` gives you the primitives; you bring the UI.
+
+```ruby
+Moderate::Report.pending             # the report queue
+Moderate::Flag.pending               # the auto-filter queue (human OR ML consumer reads the same scope)
+Moderate::Appeal.pending             # appeals awaiting a human
+
+report.resolve!(by: admin, remove_content: true, ban_user: false, note: "Removed: hate speech")
+report.dismiss!(by: admin, note: "No violation")
+appeal.uphold!(by: admin, note: "...")   # overturns the decision
+appeal.reject!(by: admin, note: "...")
+```
+
+Every action is atomic, requires a moderator + a note, runs your enforcement (content removal via the reportable's own `remove_reported_field!`, bans via your `ban_handler`), and writes to your audit log.
+
+### Use it from a controller (BYOUI)
+
+```ruby
+class Admin::ReportsController < ApplicationController
+  include Moderate::Moderation   # resolve!/dismiss! actions, strong params, redirects
+
+  before_action :require_admin
+end
+```
+
+### Integrate with [`madmin`](https://github.com/excid3/madmin)
+
+`moderate`'s models are plain ActiveRecord, so they show up in `madmin` like anything else. Generate a resource and point it at the model:
+
+```bash
+rails generate madmin:resource Moderate::Report
+```
+
+Then wire the resolve/dismiss actions to `Moderate::Report#resolve!`/`#dismiss!` from a custom member action (full walkthrough in [`docs/madmin.md`](docs/madmin.md)). The same pattern works for `Moderate::Flag` and `Moderate::Appeal`.
+
+## 🔔 Notifications & 🧾 audit — one hook each
+
+`moderate` never sends an email or writes to *your* audit log directly. It **emits events** through two hooks you wire once — so notifications fan out wherever you want, and important actions are recorded however you want.
+
+```ruby
+Moderate.configure do |config|
+  # Called for every important action — wire it to your audit system (or leave it; it no-ops):
+  config.audit = ->(event) { AuditLog.record!(event_type: event.name, data: event.payload) }
+
+  # Called for every notifiable event — fan out to email / admin Telegram / push / in-app:
+  config.notify = ->(event) do
+    case event.name
+    when :report_received, :report_decision, :affected_user_decision
+      ModerationMailer.with(event:).public_send(event.name).deliver_later   # goodmail
+    when :content_flagged, :report_received
+      Telegrama.send_message("🚩 #{event.payload[:summary]}")               # admin alert
+    end
+  end
+
+  # Optional side effects when a block happens (e.g. tear down a pending invite):
+  config.on_block = ->(blocker:, blocked:) { CancelPendingInvites.call(blocker, blocked) }
+end
+```
+
+Events carry a stable envelope (`event.name`, `event.subject`, `event.recipients`, `event.actor`, `event.payload`), so a single `notify` hook can drive **goodmail** (user emails), **telegrama** (admin alerts), and **noticed** (in-app feed + push) at once. Notify users via email/in-app **and** ping admins on Telegram from the same place. (Recipes in [`docs/notifications.md`](docs/notifications.md).)
+
+The full event vocabulary: `report_received`, `report_decision`, `affected_user_decision`, `appeal_received`, `appeal_decision`, `user_blocked`, `user_unblocked`, `user_banned`, `content_flagged`, `content_removed`.
+
+## ⚖️ DSA & app-store compliance, out of the box
+
+`moderate` is built around the rules so you don't have to read the regulation:
+
+- **DSA Art. 16 (notice & action):** a public, electronic notice form (`Moderate::Notice` intake) capturing the substantiated reason, exact URL, notifier name+email, good-faith statement, the EU **statement-of-reasons taxonomy**, and the member-state selector — with an automatic confirmation of receipt.
+- **DSA Art. 17 (statement of reasons):** decision notices state the action, the legal/contractual ground, whether automated means were used, and the redress path.
+- **DSA Art. 20 (appeals):** a free, electronic internal complaint mechanism, open ≥ 6 months, decided by a human.
+- **DSA Art. 24 (transparency):** counters you can publish (notices received, actions taken, median handling time, appeal outcomes).
+- **Apple Guideline 1.2 & Google Play UGC:** filter-before-post, in-app report **and** block, ongoing moderation, published contact — `moderate` covers all four. See the mapped checklist in [`docs/compliance.md`](docs/compliance.md).
+
+> Two taxonomies, on purpose: an in-app **community report** category set (harassment, spam, …) and a separate, regulator-aligned **DSA legal-reason** taxonomy for public notices. `moderate` ships both.
+
+## 🤓 Why the models?
+
+`rails generate moderate:install` creates four tables:
+
+- **`moderate_reports`** — a report/notice + an immutable evidence snapshot + decision metadata + the appeal window. Serves both in-app reports and public DSA notices (distinguished by `kind`).
+- **`moderate_blocks`** — the bidirectional `blocker`/`blocked` edge, with a self-block check and the SSOT relation behind `Moderate.blocked_ids_for`.
+- **`moderate_flags`** — system/auto-filter flags (source: `text_filter` / `image_filter` / `external_classifier` / `manual`), with the classifier's labels + scores; the queue both human admins and ML consumers read via `pending`.
+- **`moderate_appeals`** — DSA Art. 20 internal complaints against a decision.
+
+The migration is **adaptive**: it matches your app's primary-key type (UUID or bigint) and JSON column type (`jsonb` / `json`) automatically, so it drops cleanly into any Rails 7.1+ schema.
+
+## Configuration reference
 
-You can configure the `moderate` gem behavior by adding a `config/initializers/moderate.rb` file:
 ```ruby
 Moderate.configure do |config|
-  # Custom error message when bad words are found
-  config.error_message = "contains inappropriate language"
+  config.user_class        = "User"          # who reports/blocks/gets banned
+  config.default_filter_mode = :block        # :off / :block / :flag
+  config.filter_adapter    = :wordlist       # default text adapter
 
-  # Add your own words to the blacklist
-  config.additional_words = ["badword1", "badword2"]
+  config.audit       = ->(event) { ... }     # optional; no-op by default
+  config.notify      = ->(event) { ... }     # optional; no-op by default
+  config.on_block    = ->(blocker:, blocked:) { ... }   # optional
+  config.ban_handler = ->(user:, by:, reason:) { user.suspend! }   # how a "ban" is applied in your app
 
-  # Exclude words from the default list (false positives)
-  config.excluded_words = ["good"]
+  config.filter "Message", :body, with: :wordlist, mode: :flag
 end
 ```
 
+Reportable classes are auto-discovered from the `reportable` macro (or `include Moderate::Reportable`) — no manual registry.
+
+## Upgrading from 0.x
+
+`moderate` 1.0 is a ground-up rewrite: the old gem was a profanity validator; 1.0 is a full Trust & Safety system. The one piece of the old API that remains is the validator, now backed by the `:wordlist` adapter:
+
+```ruby
+validates :body, moderate: true     # still works — equivalent to `moderates :body, mode: :block`
+```
+
+Everything else is new. There's no automated data migration (0.x stored nothing). See [`CHANGELOG.md`](CHANGELOG.md).
+
+## Testing
+
+We use Minitest. Run the suite (a dummy Rails app under `test/dummy`, against SQLite/PostgreSQL/MySQL via Appraisals):
+
+```bash
+bundle exec rake test
+```
+

+# Compliance: DSA, App Store, and Google Play — the checklist you hand to legal
+
+Trust & Safety is the one part of your app where "I think we covered it" isn't good enough. A missing **block** button gets your build rejected by Apple. A missing **notice form** gets you a letter from a European regulator. A missing **appeal** path is a DSA violation with a fine attached. The rules are real, they're specific, and they're written by people who have never opened your codebase.
+
+So this page does the boring, load-bearing work: it maps **every requirement** from the three regimes that actually gate a UGC app — the **EU Digital Services Act**, the **Apple App Store Review Guidelines**, and the **Google Play** developer policies — to the **exact `moderate` feature** that satisfies it, with the **test** that proves it. It's written to be **printed and handed to a lawyer or a store reviewer**: each row is a claim, and each claim has a receipt.
+
+> [!NOTE]
+> `moderate` gives you the **mechanisms** the law and the stores require — the report intake, the block edge, the filter, the queue, the appeal, the statement-of-reasons, the transparency counters, the public notice form. It cannot make your **policies** or **operations** compliant for you: you still have to publish a contact address, actually read the queue, and answer notices "in a timely manner." This checklist marks which is which — **[gem]** rows are done the moment you install; **[you]** rows are things only you can do, that the gem makes easy. Don't hand legal the **[gem]** column and call it a day.
+
+> [!IMPORTANT]
+> This is engineering documentation, not legal advice. It reflects the text of the **DSA (Regulation (EU) 2022/2065)**, the **App Store Review Guidelines**, and the **Google Play Developer Program Policies** as the gem was built against them. Regulations and store rules change; your obligations depend on your size, your users, and your content. Have your own counsel confirm the mapping before you rely on it.
+
+---
+
+## How to read this
+
+Every checklist row has four columns:
+
+| Column | What it means |
+| --- | --- |
+| **Requirement** | The specific obligation, quoted or closely paraphrased, with its article/guideline number. |
+| **How `moderate` satisfies it** | The concrete feature, model, hook, or method that covers it. |
+| **Who** | **[gem]** = built in, true the moment you install. **[you]** = your responsibility, made easy by the gem. **[gem + you]** = gem does the mechanism, you wire one hook or write one line. |
+| **Proof** | The test in the suite (or the manual check) that demonstrates it. |
+
+The **Proof** column points at `test/` paths. Run the whole thing with `bundle exec rake test`; the named files are your evidence that the mechanism actually works, not just that it's documented.
+
+---
+
+## 1. EU Digital Services Act (Regulation (EU) 2022/2065)
+
+The DSA applies to any "hosting service" — which includes basically any app that stores user-generated content — **that serves recipients in the EU**, regardless of where you're based. The four articles that matter for a small/mid app (you are almost certainly **not** a "Very Large Online Platform," which carries extra duties this gem does not cover) are **16, 17, 20, and 24**. `moderate` is organized around exactly these.
+
+> [!NOTE]
+> **Scope honesty.** `moderate` targets the obligations that apply to ordinary hosting services and online platforms. It does **not** implement VLOP-only duties (risk assessments, independent audits, the transparency database submission, vetted-researcher data access, Art. 34–43). If you cross 45M monthly EU users, you have a much bigger compliance program than any gem — talk to specialists.
+
+### Art. 16 — Notice and action mechanisms
+
+> Providers shall put mechanisms in place to allow **any individual or entity** to notify them of allegedly illegal content, **by electronic means**, that are **easy to access and user-friendly**.
+
+| Requirement | How `moderate` satisfies it | Who | Proof |
+| --- | --- | --- | --- |
+| A public, **electronic** notice mechanism, open to **anyone** (not just logged-in users). | The mountable notice engine — `mount Moderate::Engine => "/legal"` — serves a public form at `/legal/notices/new`. See [`docs/dsa-notice-form.md`](dsa-notice-form.md). | **[gem]** | `test/integration/notices_form_test.rb` |
+| Notice contains a **sufficiently substantiated explanation** of why the content is illegal — Art. 16(2)(a). | `explanation` field, required and validated on `Moderate::Notice`. | **[gem]** | `test/models/notice_validations_test.rb` |
+| Notice contains the **exact electronic location** (URL) — Art. 16(2)(b). | `content_url` field, validated as an `http(s)` URL; the model resolves it to a reportable record for the evidence snapshot. | **[gem]** | `test/models/notice_validations_test.rb` |
+| Notice contains the **name and email** of the notifier — Art. 16(2)(c). | `notifier_name` + `notifier_email`, required and email-validated. | **[gem]** | `test/models/notice_validations_test.rb` |
+| **Anonymity carve-out**: name/email are **not** required for notices alleging certain offences against minors (CSAM and related, Art. 16(2)(c) proviso). | When `legal_reason` is `:csam`, the model **waives** the `notifier_name`/`notifier_email` requirement; the form hides those fields. | **[gem]** | `test/models/notice_csam_anonymous_test.rb` |
+| A **good-faith statement** that the information is accurate and complete — Art. 16(2)(d). | `good_faith` checkbox; the save is rejected unless it's `true`. | **[gem]** | `test/models/notice_validations_test.rb` |
+| **Confirmation of receipt**, sent to the notifier **without undue delay** — Art. 16(4). | On save, `Moderate::Notice` fires the `notice_received` event through `config.notify`; you wire it to your mailer once (e.g. `goodmail`) for the receipt, and the form also shows an on-screen receipt with an opaque `reference`. | **[gem + you]** | `test/models/notice_receipt_event_test.rb` |
+| Notice the provider that the decision **and** the redress options are communicated — Art. 16(5). | Acting on the report (resolve/dismiss) emits `report_decision` (and `affected_user_decision`) carrying the statement of reasons; see Art. 17 below. | **[gem + you]** | `test/services/resolve_emits_decision_test.rb` |
+| Decisions taken in a **timely, diligent, non-arbitrary and objective manner** — Art. 16(6). | The notice lands in `Moderate::Report.pending` — the same queue as in-app reports — with full evidence; you act on it. The gem records who decided, when, and why (mandatory moderator + note on every action). | **[gem + you]** | `test/models/report_pending_scope_test.rb` |
+
+> [!TIP]
+> Don't want to mount the engine? You can build your own public page and call `Moderate::Notice` directly — every Art. 16 validation, the snapshot, the `reference`, and the `notice_received` event still apply. Mounting is the fast path; the model is the full-control path. See [Staying optional](dsa-notice-form.md#staying-optional-ignore-the-engine-entirely).
+
+### Art. 17 — Statement of reasons
+
+> Where a provider restricts content, it shall provide a **clear and specific statement of reasons** to the affected recipient.
+
+The statement must include, at minimum: the **restriction imposed** (and its scope), the **facts and circumstances** relied on, whether **automated means** were used, the **legal or contractual ground**, and information on **redress** (internal complaints, out-of-court dispute settlement, judicial remedy).
+
+| Requirement | How `moderate` satisfies it | Who | Proof |
+| --- | --- | --- | --- |
+| State the **specific restriction** imposed and its scope (content removed? account suspended?). | Every resolution records its action (`remove_content:`, `ban_user:`) and emits `affected_user_decision` with that action in `event.payload`. | **[gem]** | `test/services/resolve_records_action_test.rb` |
+| State the **facts and circumstances** relied on. | The immutable **evidence snapshot** taken at report time travels with the decision; the moderator's mandatory `note:` is the human-readable ground. | **[gem]** | `test/models/evidence_snapshot_test.rb` |
+| State whether **automated means** were used in detection or decision — Art. 17(3)(c). | Reports/flags carry their `source` (`:wordlist`, `:image`, a remote adapter, or `:manual`). A decision acting on an auto-`Moderate::Flag` is flagged as automated-means in the `affected_user_decision` payload; a human report is not. | **[gem]** | `test/services/automated_means_flag_test.rb` |
+| State the **legal or contractual ground**. | For DSA notices, the `legal_reason` (from `Moderate::DSA_LEGAL_REASONS`) is the legal ground; for in-app reports, the community `category` + your `note:` is the contractual (terms-of-service) ground. Both ride in the decision payload. | **[gem + you]** | `test/services/decision_ground_test.rb` |
+| Communicate **redress** options (internal complaint, out-of-court, judicial). | The `affected_user_decision` event carries the appeal entry point; you render the redress text in your decision email (the gem ships the data; the copy is yours, because it names your jurisdiction). | **[gem + you]** | `test/services/decision_includes_redress_test.rb` |
+| Deliver the statement to the **affected recipient** (the content owner), not just the reporter. | Two distinct events fire: `report_decision` → the **reporter**; `affected_user_decision` → the **content owner** (resolved via the reportable's `reported_owner`). You wire both. | **[gem + you]** | `test/services/decision_recipients_test.rb` |
+
+> [!NOTE]
+> **Why two decision events.** Art. 16(5) wants the **notifier** informed; Art. 17 wants the **affected user** informed — they are different people with different rights. `moderate` keeps them separate (`report_decision` vs `affected_user_decision`) so your one `notify` hook sends the right message to the right person. Collapsing them into one email is a classic DSA mistake. See [Notifications](../README.md#-notifications---audit--one-hook-each).
+
+### Art. 20 — Internal complaint-handling system (appeals)
+
+> Providers shall provide recipients with access to an **effective internal complaint-handling system**, **free of charge**, for at least **six months** after a decision, with complaints handled in a **timely, non-discriminatory, diligent and non-arbitrary manner** and **not solely on automated means**.
+
+| Requirement | How `moderate` satisfies it | Who | Proof |
+| --- | --- | --- | --- |
+| An **internal** appeal mechanism against moderation decisions. | `Moderate::Appeal` — a complaint filed against a resolved report/notice; the queue is `Moderate::Appeal.pending`. | **[gem]** | `test/models/appeal_test.rb` |
+| **Free of charge.** | There is no charge anywhere in the appeal path — it's just a record + a queue. (You simply don't bill for it.) | **[gem]** | n/a (no payment code exists in the path) |
+| Open for **at least six months** after the decision. | Each report stores its **appeal window**; the gem's default window is **6 months** and `Moderate::Appeal` refuses to open against a decision whose window has closed. | **[gem]** | `test/models/appeal_window_test.rb` |
+| Decisions **reversible** — uphold the complaint and reverse the action. | `appeal.uphold!(by:, note:)` overturns the original decision (and runs the reverse enforcement); `appeal.reject!(by:, note:)` confirms it. | **[gem]** | `test/services/appeal_uphold_test.rb` |
+| **Not solely automated** — a human decides the complaint. | `uphold!`/`reject!` **require** a `by:` moderator and a `note:`; there is no path to auto-decide an appeal. | **[gem]** | `test/services/appeal_requires_human_test.rb` |
+| Inform the complainant of the **appeal decision** and remaining redress (out-of-court / judicial). | Resolving an appeal emits `appeal_decision` to the complainant; you render the out-of-court / judicial redress copy. | **[gem + you]** | `test/services/appeal_decision_event_test.rb` |
+
+### Art. 24 — Transparency reporting
+
+> Providers shall publish, at least **once a year**, reports on their content moderation, including the **number of notices** received, **action taken**, **use of automated means**, and **complaints** received and their outcomes.
+
+| Requirement | How `moderate` satisfies it | Who | Proof |
+| --- | --- | --- | --- |
+| Count of **notices received** (by type/ground). | `Moderate.transparency` aggregates `moderate_reports` by `kind` and `legal_reason`/`category`. | **[gem]** | `test/services/transparency_counts_test.rb` |
+| Count of **actions taken** (removals, bans, dismissals). | The same aggregation tallies resolutions by action and dismissals. | **[gem]** | `test/services/transparency_counts_test.rb` |
+| **Median handling time** (notice → decision). | Computed from each report's received-at vs decided-at timestamps. | **[gem]** | `test/services/transparency_timing_test.rb` |
+| Use of **automated means** in moderation. | Counts of decisions acting on auto-`Moderate::Flag`s vs human reports, from the `source` column. | **[gem]** | `test/services/transparency_automated_test.rb` |
+| **Appeals** received and their **outcomes** (upheld / rejected). | Aggregation over `moderate_appeals` by status. | **[gem]** | `test/services/transparency_appeals_test.rb` |
+| **Publish** the report (at least annually). | The gem produces the numbers; **you** publish them (a `/transparency` page, a PDF, whatever) — only you know your reporting period and format. | **[you]** | manual: render `Moderate.transparency(from:, to:)` |
+
+> [!TIP]
+> `Moderate.transparency(from: 1.year.ago, to: Time.current)` returns a plain hash you can drop straight into a view, a JSON endpoint, or a rake task that emails it to you each January. The counters are the regulator-aligned ones — same taxonomy as the notice form (`Moderate::DSA_LEGAL_REASONS`) — so the published numbers line up with the intake.

+
+## 2. Apple App Store — Guideline 1.2 (User-Generated Content)
+
+Apple is blunt: an app with UGC that lacks these gets **rejected**, and rejection is the most common reason a social/community app fails review. Guideline 1.2 lists four mechanisms; **all four are required**, and reviewers test them by hand during review.
+
+> Apps with user-generated content … must include: **(a)** a method for **filtering objectionable material** from being posted, **(b)** a mechanism to **report** offensive content and timely responses to concerns, **(c)** the ability to **block abusive users**, and **(d)** **published contact information** so users can easily reach you.
+
+| Requirement | How `moderate` satisfies it | Who | Proof |
+| --- | --- | --- | --- |
+| **(a)** A method to **filter objectionable material** before it's posted. | `moderates :field` with `mode: :block` rejects the offending write before save; the default `:wordlist` adapter is multilingual and evasion-resistant, and you can register an image / remote adapter for stronger checks. | **[gem]** | `test/models/filtering_block_mode_test.rb` |
+| **(b)** A mechanism to **report** offensive content. | `current_user.report!(content, category:)` in-app; `reportable` content exposes `reports`, `reported?`, `flagged?`; the `moderate_report_link` helper drops the button into any view. | **[gem]** | `test/models/reportable_test.rb`, `test/helpers/report_link_test.rb` |
+| **(b)** **Timely responses** to reports. | The report lands in `Moderate::Report.pending` with a snapshot; the reporter gets a `report_received` receipt immediately, and a `report_decision` when you act. (Acting promptly is on you — the gem surfaces the queue and the events.) | **[gem + you]** | `test/services/report_received_event_test.rb` |
+| **(c)** The ability to **block abusive users**. | `current_user.block!(other)` — bidirectional, idempotent, audited; enforce it everywhere with the single `Moderate.blocked_ids_for(user)` query. | **[gem]** | `test/models/block_test.rb` |
+| **(d)** **Published contact information** to reach the developer. | The notice-engine root (`/legal`) is a natural home for your contact/abuse address; the gem gives you the page, **you** publish the address (Apple wants a real human-reachable contact). | **[gem + you]** | manual: contact shown in-app + on the notice page |
+
+> [!IMPORTANT]
+> **Guideline 1.2 also expects an EULA acknowledgement** for UGC apps: users must agree there's **no tolerance for objectionable content or abusive behavior**. That's a one-line acceptance in your signup/terms — `moderate` doesn't own your terms screen, but the **community-report categories** (`:harassment`, `:spam`, …) are what your EULA's "objectionable content" clause should enumerate, so the words match the buttons. Keep your terms and your report categories in sync.
+
+> [!TIP]
+> When you respond to App Review's inevitable "show us your moderation" question, point them at: the in-app **Report** button (1.2b), the **Block** action on a profile (1.2c), the fact that a banned-word post is **rejected** (1.2a), and your **contact** link (1.2d). Those are the four taps a reviewer makes. The rows above are the four they correspond to.
+
+---
+
+## 3. Google Play — User-Generated Content policy
+
+Google Play's UGC policy overlaps heavily with Apple's but is explicit about **two things Apple states more loosely**: blocking/reporting must cover **both users and content**, and you must do **ongoing** moderation (not just provide the buttons). It also requires an in-app way to **accept terms / acceptable-use** before contributing UGC.
+
+> Apps with UGC must: provide an in-app system for **reporting and blocking objectionable users and content**; provide a method to **moderate UGC**; and require users to **accept the app's terms of use / user policy** before creating or uploading UGC.
+
+| Requirement | How `moderate` satisfies it | Who | Proof |
+| --- | --- | --- | --- |
+| In-app **reporting** of objectionable **content**. | `current_user.report!(content, category:)`; any model that is `reportable` can be reported. | **[gem]** | `test/models/reportable_test.rb` |
+| In-app **reporting** of objectionable **users**. | A user model with `has_moderation` is itself reportable: `current_user.report!(other_user, category: :impersonation)`. | **[gem]** | `test/models/report_user_test.rb` |
+| In-app **blocking** of objectionable **users**. | `current_user.block!(other)` — the bidirectional safety edge. | **[gem]** | `test/models/block_test.rb` |
+| In-app **blocking / hiding** of objectionable **content**. | Filter the blocked pair's content out of any feed with `Moderate.blocked_ids_for(current_user)` — the single source-of-truth query you apply in search, inbox, and listings. | **[gem]** | `test/models/blocked_ids_scope_test.rb` |
+| A method to **moderate UGC** (a real review surface, not just intake). | `Moderate::Report.pending` / `Moderate::Flag.pending` give admins the queue; `resolve!`/`dismiss!`/`remove_content`/`ban_user` are the audited actions. (BYOUI — you bind these to your admin; see [`docs/madmin.md`](madmin.md).) | **[gem + you]** | `test/services/resolve_test.rb` |
+| **Ongoing** moderation, including proactive detection. | Pre-publication filtering (`moderates`) catches content at write time; `:flag` mode queues borderline content for review **after commit**; both feed the same admin queue. The mechanism is continuous, not one-shot. | **[gem]** | `test/models/filtering_flag_mode_test.rb` |
+| Users **accept terms / acceptable-use** before contributing UGC. | This is your signup/terms gate — `moderate` doesn't own it — but, as with Apple, your acceptable-use policy should enumerate the **community-report categories** so the terms and the report buttons describe the same prohibited behavior. | **[you]** | manual: terms acceptance in your onboarding |
+
+> [!NOTE]
+> **"Both users and content" is the row people miss.** Plenty of apps add a "Report comment" button and stop there. Play wants you to be able to report **and** block **both** a person and a thing. `moderate` covers all four cells because a user model with `has_moderation` is *also* `reportable`, and blocking is enforced over content via `blocked_ids_for`. If you only made content `reportable` and never made users blockable, you'd pass Apple's spot check and still fail Play's policy.
+

+
+## 4. The one-page summary (hand this to legal)
+
+If you read nothing else, this is the table that says "we did the thing."
+
+| Regime | Obligation | `moderate` mechanism | Status |
+| --- | --- | --- | --- |
+| **DSA Art. 16** | Public electronic notice + confirmation of receipt | Notice engine (`mount Moderate::Engine`) + `notice_received` event | ✅ gem (+ wire 1 mailer) |
+| **DSA Art. 17** | Statement of reasons (action, ground, automated-means, redress) | `affected_user_decision` event carrying action + ground + source + appeal path | ✅ gem (+ wire 1 mailer) |
+| **DSA Art. 20** | Free internal appeals, ≥ 6 months, human-decided | `Moderate::Appeal` + 6-month window + `by:`/`note:`-required `uphold!`/`reject!` | ✅ gem |
+| **DSA Art. 24** | Annual transparency report | `Moderate.transparency` counters | ✅ gem (you publish) |
+| **Apple 1.2(a)** | Filter objectionable content | `moderates :field, mode: :block` | ✅ gem |
+| **Apple 1.2(b)** | Report + timely response | `report!` + `Report.pending` + `report_decision` | ✅ gem (you respond) |
+| **Apple 1.2(c)** | Block abusive users | `block!` + `blocked_ids_for` | ✅ gem |
+| **Apple 1.2(d)** | Published contact | `/legal` page | ✅ gem (you publish address) |
+| **Play UGC** | Report + block, **users and content** | `report!`/`block!` on users; `reportable` + `blocked_ids_for` on content | ✅ gem |
+| **Play UGC** | Ongoing moderation surface | `Flag.pending` + `:flag`-mode filtering | ✅ gem (you review) |
+| **Play UGC** | Accept terms before UGC | your onboarding gate | ⬜ you (categories align) |
+
+Legend: **✅ gem** — the mechanism ships and is tested. **⬜ you** — your operational/policy step that the gem makes straightforward.
+
+> [!WARNING]
+> A green checklist is necessary, not sufficient. The stores and the DSA judge you on **behavior over time** — that you actually read the queue, answer notices, and decide appeals — not just that the buttons exist. `moderate` makes every one of those actions a one-liner with a built-in audit trail (`config.audit`), so doing the operational work is cheap. **Do it.** The mechanisms keep you compliant only if you keep using them.

+# Configuration reference
+
+Everything `moderate` lets you configure lives in one initializer, written in the `Moderate.configure do |config|` block. `rails generate moderate:install` drops a fully-commented `config/initializers/moderate.rb` with every option present and annotated; this doc is the reference for what each one does, with copy-paste examples.
+
+Every option has a sensible default, so the minimum viable config is a single line:
+
+```ruby
+# config/initializers/moderate.rb
+Moderate.configure do |config|
+  config.user_class = "User"
+end
+```
+
+That alone gives you reporting, blocking, the default `:wordlist` filter in `:block` mode, and the moderation queue. Everything below is opt-in refinement.
+
+> [!NOTE]
+> Config is read at the point of use, not frozen at boot — class names are stored as strings and constantized lazily, so the initializer works no matter when your app loads. The block is validated at the end of `configure`, so a typo'd mode or unknown adapter raises a plain-English `ArgumentError` immediately instead of failing mysteriously later.
+
+---
+
+## The whole surface at a glance
+
+```ruby
+Moderate.configure do |config|
+  # --- Identity -------------------------------------------------------------
+  config.user_class          = "User"        # who reports / blocks / gets reported / gets banned
+
+  # --- Filtering ------------------------------------------------------------
+  config.default_filter_mode = :block        # :off / :block / :flag  (used by `moderates` w/o a mode)
+  config.filter_adapter      = :wordlist     # default text adapter
+  config.additional_words    = %w[…]         # extra :wordlist entries
+  config.excluded_words      = %w[…]         # :wordlist false-positives to never flag
+
+  config.register_adapter :openai, OpenAIModerator.new   # bring your own remote adapter
+  config.filter "Message", :body, with: :wordlist, mode: :flag   # per-field policy in one place
+
+  # --- Hooks (all no-op by default) ----------------------------------------
+  config.audit       = ->(event) { … }                    # record important actions
+  config.notify      = ->(event) { … }                    # fan out emails / alerts / push
+  config.on_block    = ->(blocker:, blocked:) { … }       # side effects when a block happens
+  config.ban_handler = ->(user:, by:, reason:) { … }      # how a "ban" is applied in YOUR app
+
+  # --- Misc -----------------------------------------------------------------
+  config.locale = :en                        # locale for copy moderate generates itself
+end
+```
+
+The DSA notice-form options (`notice_form_enabled`, `notice_rate_limit`, `notice_turnstile_*`, `notice_parent_controller`, `notice_captcha_verifier`) are documented in their own guide — see [The DSA notice form](dsa-notice-form.md#configuration-reference-notice-form). They're omitted here to keep this focused on the core T&S surface.
+
+---
+
+## Identity
+
+### `user_class`
+
+```ruby
+config.user_class = "User"   # default: "User"
+```
+
+The model that **acts** in your Trust & Safety system: it reports, it blocks, it gets reported, and it gets banned. This is the model where you add the actor macro:
+
+```ruby
+class User < ApplicationRecord
+  has_moderation            # the sugar (preferred) — gains report!/block!/blocks?/blocked_with?…
+  # include Moderate::Actor # the documented, exactly-equivalent include form
+end
+```
+
+Stored as a **string** and constantized lazily, so it doesn't matter whether the class is loaded yet when the initializer runs. It's usually `"User"`, but it can be anything that represents "a person who acts" — `"Account"`, `"Member"`, etc. `moderate` deliberately doesn't own auth or current-user; you tell it the class, your auth gem (Devise, etc.) tells it who's logged in.
+
+---
+
+## Filtering
+
+`moderate` filters text and images **before they're saved**, declared per field with the `moderates` macro. The three config options below set the *defaults* that macro uses; you can always override per field.
+
+### `default_filter_mode`
+
+```ruby
+config.default_filter_mode = :block   # default: :block  (:off / :block / :flag)
+```
+
+The mode a bare `moderates :field` uses when you don't pass `mode:`:
+
+- **`:off`** — no check. (Useful as a global default if you want filtering opt-in per field.)
+- **`:block`** — the write is **rejected** with a validation error if the filter trips. Best for public, high-trust fields (a profile bio, a listing title).
+- **`:flag`** — the write **succeeds**, and a `Moderate::Flag` is created **after commit** for review. Best for DMs and chat, where blocking mid-conversation is hostile UX.
+
+```ruby
+class Message < ApplicationRecord
+  moderates :body                  # uses default_filter_mode
+end
+
+class Profile < ApplicationRecord
+  moderates :bio,    mode: :block  # override: reject the save
+  moderates :avatar, mode: :flag, with: :image
+end
+```
+
+> [!IMPORTANT]
+> `:flag` never lives in a validator. Validators must be side-effect-free, and a flag created inside a rolled-back transaction would silently vanish — so `moderate` creates the flag **after commit**, correctly, for you. This is the whole reason `:flag` is a `moderates` mode and not something you can hand-roll with `validates`.
+
+### `filter_adapter`
+
+```ruby
+config.filter_adapter = :wordlist   # default: :wordlist
+```
+
+The default **text** adapter used by `moderates :field` and `Moderate.classify`. Every adapter — built-in or yours — implements the same tiny contract, so they're interchangeable per field:
+
+```ruby
+adapter.classify(value)  # => Moderate::Result(allowed:, categories:, scores:)
+```
+
+Two adapters ship built in:
+
+| Adapter | Use it for | Notes |
+| --- | --- | --- |
+| `:wordlist` (default) | text | Fast, multilingual, **offline**. Unicode + leetspeak + spacing-evasion resistant. Ships `en`/`es` lists; extend with `additional_words` / `excluded_words`. |
+| `:image` | images / avatars / attachments | Pluggable safe-search / NSFW backend; runs async in `:flag` mode. |
+
+For anything nuanced — context-aware text, a hosted moderation API — you **bring and name your own adapter** with `register_adapter` (next section). `moderate` intentionally does **not** ship a built-in "LLM" adapter: the contract is `classify(value) → Result`, and whether the backend behind your adapter is an LLM, a hosted endpoint, or a regex is your call, not the gem's.
+
+### `register_adapter` — bring your own backend
+
+An adapter is just an object that responds to `classify` and returns a `Moderate::Result`. Register it once under a name you choose, then reference it anywhere by that name:
+
+```ruby
+class OpenAIModerator
+  def classify(value)
+    resp = OpenAI.moderate(value)   # your call
+    Moderate::Result.new(
+      allowed:    !resp.flagged?,
+      categories: resp.categories,                 # e.g. [:hate, :harassment]
+      scores:     resp.category_scores             # { hate: 0.92, harassment: 0.13 }  (0..1)
+    )
+  end
+end
+
+Moderate.configure do |config|
+  config.register_adapter :openai, OpenAIModerator.new
+
+  # now use it by name, per field:
+  config.filter "Comment", :body, with: :openai, mode: :flag
+end
+```
+
+```ruby
+# or right on the model:
+class Comment < ApplicationRecord
+  moderates :body, with: :openai, mode: :flag
+end
+```
+
+The name is **yours** — `:openai`, `:replicate`, `:hive`, `:my_classifier`, whatever reads well in your models. The `source` recorded on resulting `Moderate::Flag`s is that name, so your moderation queue shows exactly which backend flagged each item.
+
+### `additional_words` / `excluded_words`
+
+```ruby
+config.additional_words = %w[customword anotherword]   # default: []
+config.excluded_words   = %w[scunthorpe assangea]      # default: []
+```
+
+Two layers on top of the built-in `:wordlist`:
+
+- **`additional_words`** — domain-specific terms you want caught that aren't in the shipped lists.
+- **`excluded_words`** — false positives you never want flagged (the classic "Scunthorpe problem" — legitimate words that contain a substring of a banned one).
+
+Both apply only to the `:wordlist` adapter. (The old `0.x` `additional_words`/`excluded_words` config keys carry over unchanged — see [Upgrading from 0.x](../README.md#upgrading-from-0x).)
+
+### `filter` — per-field policy in the initializer
+
+If you'd rather keep all your Trust & Safety policy in one place instead of sprinkling `moderates` across models, declare per-field filters in the initializer. Same effect, same arguments:
+
+```ruby
+config.filter "Message", :body,   with: :wordlist, mode: :flag
+config.filter "Profile", :bio,    with: :wordlist, mode: :block
+config.filter "Profile", :avatar, with: :image,    mode: :flag
+```
+
+`config.filter "Class", :field, with:, mode:` is the initializer twin of `moderates :field, with:, mode:` on the model. Use whichever fits your taste; you can mix both. (Reportable classes themselves are auto-discovered from the reportable macro — there's no separate registry to maintain.)
+
+---
+
+## Hooks
+
+`moderate` never sends an email, writes to *your* audit log, or decides what "banned" means in your app. It **emits events** and **calls handlers** you wire once. All four hooks default to a no-op, so the gem works untouched — wire them as you need them.
+
+### `audit` — record important actions
+
+```ruby
+config.audit = ->(event) { AuditLog.record!(event_type: event.name, data: event.payload) }
+```
+
+Called for **every important action** so you can write it to your own audit system. The gem never touches your audit log directly. The event carries a stable envelope:
+
+```ruby
+event.name        # Symbol, e.g. :report_decision
+event.subject     # the record acted on (a Report, Block, Flag, Appeal…)
+event.actor       # who took the action (a moderator, a user, or nil for system)
+event.recipients  # who should be notified (Array)
+event.payload     # Hash of event-specific context (includes :summary)
+event.to_h        # the whole envelope as a Hash
+```
+
+### `notify` — fan out anywhere
+
+```ruby
+config.notify = ->(event) do
+  case event.name
+  when :report_received, :report_decision, :affected_user_decision
+    ModerationMailer.with(event: event).public_send(event.name).deliver_later   # goodmail
+  when :content_flagged
+    Telegrama.send_message("🚩 #{event.payload[:summary]}")                      # admin alert
+  end
+end
+```
+
+Called for **every notifiable event**. One hook drives them all — `goodmail` for user emails, `telegrama` for admin alerts, `noticed` for in-app feed + push — because every event shares the same envelope. The full vocabulary:
+
+```
+report_received   report_decision   affected_user_decision
+appeal_received   appeal_decision
+user_blocked      user_unblocked    user_banned
+content_flagged   content_removed
+```
+
+> [!IMPORTANT]
+> Keep `notify` (and `audit`) **fast** — use background jobs (`deliver_later`, `perform_later`). These hooks run inside the moderation action's flow; slow work here slows down every decision and every block.
+
+### `on_block` — side effects when a block happens
+
+```ruby
+config.on_block = ->(blocker:, blocked:) { CancelPendingInvites.call(blocker, blocked) }
+```
+
+Optional teardown when one user blocks another — cancel a pending invite, leave a shared room, drop a follow. Signature is **keyword args** (`blocker:`, `blocked:`). No-op by default. (A `user_blocked` event also fires through `notify`; use `on_block` for *domain side effects* and `notify` for *messaging*.)
+
+### `ban_handler` — what "banned" means in your app
+
+```ruby
+config.ban_handler = ->(user:, by:, reason:) { user.suspend!(reason: reason) }
+```
+
+`moderate` doesn't own your user lifecycle, so it **never bans a user itself**. When a moderator resolves a report with `ban_user: true` (see [the madmin queue](madmin.md#step-3--the-controller-call-the-gems-decision-methods)), this proc decides what "banned" means in your domain — `suspend!`, soft-delete, flip a flag, revoke sessions, whatever. Signature is **keyword args** (`user:`, `by:`, `reason:`). No-op by default — the decision still audits and notifies even if you haven't wired a ban yet, so you're never silently dropping the action.
+
+---
+
+## Misc
+
+### `locale`
+
+```ruby
+config.locale = :en   # default: your app's I18n.default_locale
+```
+
+The locale for copy `moderate` generates on its own — filter validation messages, the DSA statement-of-reasons taxonomy labels, the notice-form strings. Leave it unset to follow `I18n.default_locale`.
+
+---
+
+## How the macros relate to config
+
+Config sets defaults; the model macros consume them. The two halves of the API:
+
+| In the model | In the initializer | What it controls |
+| --- | --- | --- |
+| `has_moderation` (or `include Moderate::Actor`) | `config.user_class` | Who can report/block and be reported/banned |
+| `reportable :title, :description` (or `include Moderate::Reportable`) | — (auto-discovered) | Which content is reportable, and which fields |
+| `moderates :body, with:, mode:` | `config.default_filter_mode`, `config.filter_adapter`, `config.filter "…"` | Pre-publication filtering per field |
+
+Both sugar macros have an exactly-equivalent `include` form for include-purists — `has_moderation` ⇔ `include Moderate::Actor`, `reportable` ⇔ `include Moderate::Reportable`. The sugar is preferred because it reads as plain English alongside the rest of your stack (`has_credits`, `has_wallets`, `has_api_keys`), but they compile to the same thing.
+
+---
+
+## Validation & errors
+
+`moderate` validates your config at the end of `configure` and raises a plain-English `ArgumentError` on a bad value:
+
+```ruby
+config.default_filter_mode = :reject
+# => ArgumentError: default_filter_mode must be one of: off, block, flag
+
+config.filter "Message", :body, with: :gpt5, mode: :flag
+# => ArgumentError: unknown filter adapter :gpt5 — built-ins are :wordlist, :image;
+#    register your own with `config.register_adapter :gpt5, MyAdapter.new`
+```
+
+Modes and adapter names are normalized (`to_s.strip.downcase.to_sym`), so `"Block"`, `:block`, and `" block "` all mean the same thing. This matches the validating-setter convention across the ecosystem (`usage_credits` `default_currency=`, `wallets` `default_asset=`).

+# The DSA notice form — a mountable, X-style legal-notice intake
+
+The EU **Digital Services Act, Article 16 ("Notice and action")** says every hosting service that serves EU users must offer a **public, electronic** way for *anyone* — not just logged-in users — to flag illegal content, and must **acknowledge receipt** of that notice. This is the form you see at the bottom of X, YouTube, Reddit: "Report illegal content (EU)". It is a hard requirement, it is separate from your in-app "Report" button, and it is exactly the kind of legally-loaded plumbing `moderate` exists to take off your plate.
+
+So `moderate` ships it as a **mountable Rails engine**: one line in your routes and you have a compliant, public notice form live at `/legal/notices/new`. The form, the controller, the model, the Turnstile gate, the rate-limit, and the confirmation-of-receipt are all done for you. The default view is plain, accessible, and CSS-framework-agnostic — and it's **overridable the way Devise does it**: run one generator to eject the templates into your app and style them to match your brand.
+
+It is also **completely optional**. If you'd rather build the public notice page yourself (you already have a design system, you want it inside an existing `/legal` controller, whatever), don't mount the engine — use `Moderate::Notice` directly and skip everything below. The engine is a convenience, not a dependency.
+
+> [!NOTE]
+> This is the **public, regulator-facing** form (DSA Art. 16). It is *not* the in-app "Report this comment" button (that's `current_user.report!(...)` from [the Actors section](../README.md#-actors-report--block)) and it is *not* the admin moderation queue (that's BYOUI — `moderate` gives you the primitives). Two intakes, one `moderate_reports` table, distinguished by `kind`. See [why the models](../README.md#-why-the-models).
+
+---
+
+## TL;DR
+
+```ruby
+# config/routes.rb
+mount Moderate::Engine => "/legal"
+```
+
+```ruby
+# config/initializers/moderate.rb
+Moderate.configure do |config|
+  config.notice_form_enabled = true               # default; flip to false to hard-disable the engine
+  config.notice_turnstile_site_key   = ENV["TURNSTILE_SITE_KEY"]    # optional bot gate
+  config.notice_turnstile_secret_key = ENV["TURNSTILE_SECRET_KEY"]
+  config.notice_rate_limit = { max: 5, within: 1.hour }            # per-IP throttle
+end
+```
+
+That's it — `GET /legal/notices/new` renders the form, `POST /legal/notices` validates + persists a `Moderate::Notice`, fires the `notice_received` notification (your confirmation-of-receipt email + admin alert), and shows the submitter a receipt with a reference number.
+
+Want to restyle it? Eject the views, then edit them:
+
+```bash
+rails generate moderate:views
+# => creates app/views/moderate/notices/new.html.erb (and friends) in YOUR app
+```
+
+---
+
+## Why an engine (and why like Devise)
+
+Most of `moderate` is deliberately **UI-agnostic** — Trust & Safety lives in admin surfaces, and we don't presume to own your admin chrome. The DSA notice form is the **one exception**, for three reasons:
+
+1. **It must exist and it must be public.** Unlike the admin queue (which you'd build anyway), the Art. 16 form is a legal must-have that has nothing to do with your product UI. Shipping it means most apps get compliant with one line instead of researching the regulation.
+2. **The fields are dictated by law, not by you.** The legal-reason taxonomy, the good-faith statement, the "exact URL" requirement, the EU member-state selector — these come straight from the DSA. There's no product decision to make, so there's nothing to design. We can ship a correct default.
+3. **You still own the look.** A bundled-but-overridable view is the best of both: it works out of the box, and you can make it yours without forking the gem.
+
+That third point is the **Devise pattern**, and we copy it on purpose because every Rails developer already understands it:
+
+| Devise | `moderate` |
+| --- | --- |
+| `mount` is implicit via `devise_for` | `mount Moderate::Engine => "/legal"` |
+| Views ship inside the gem | Views ship inside the engine (`app/views/moderate/notices/`) |
+| `rails g devise:views` copies them to your app | `rails g moderate:views` copies them to your app |
+| `config.parent_controller` | `config.notice_parent_controller` |
+| Rails view lookup prefers `app/views` over the gem | identical — an ejected view **shadows** the bundled one, zero config |
+| Works untouched if you never eject | Works untouched if you never eject |
+
+The magic in both is the same boring Rails fact: **the host app's `app/views` sits ahead of any engine's view paths in the lookup chain.** So when you run `moderate:views` and a file appears at `app/views/moderate/notices/new.html.erb`, Rails renders *yours* instead of the gem's — no registration, no config flag, no monkey-patch. Delete your copy and the gem's default comes back.
+
+---
+
+## How it mounts
+
+`Moderate::Engine` is an **isolated** engine (`isolate_namespace Moderate`), so its routes, controllers, helpers, and table prefixes never collide with your app. You mount it wherever you want the public form to live:
+
+```ruby
+# config/routes.rb
+Rails.application.routes.draw do
+  mount Moderate::Engine => "/legal"     # form at /legal/notices/new
+  # ...your app routes
+end
+```
+
+Common mount points:
+
+```ruby
+mount Moderate::Engine => "/legal"        # → /legal/notices/new   (recommended)
+mount Moderate::Engine => "/dsa"          # → /dsa/notices/new
+mount Moderate::Engine => "/report"       # → /report/notices/new
+```
+
+The engine's routes (in the gem, you never write these):
+
+```ruby
+# config/routes.rb inside the engine
+Moderate::Engine.routes.draw do
+  resources :notices, only: [:new, :create, :show], path: "notices"
+  root to: "notices#new"
+end
+```
+
+- `GET  /legal/notices/new` — the form
+- `POST /legal/notices` — submit
+- `GET  /legal/notices/:reference` — the public receipt (looked up by opaque `reference`, never by sequential `id`)
+- `GET  /legal` — the engine root redirects to the form
+
+Link to it from your footer using the engine's named routes (mounted engines expose a helper named after the mount, here `moderate`):
+
+```erb
+<%= link_to "Report illegal content (EU)", moderate.new_notice_path %>
+```
+
+> [!TIP]
+> Want the canonical "DSA point of contact" page the regulation also asks for (Art. 11/12)? The same engine root is a fine place to host a short page that links to the form and lists your contact address — but that's content, not code, so we leave the copy to you. Eject the views and edit `new.html.erb`'s intro block.
+
+---
+
+## The controller / model boundary
+
+We keep the split clean and obvious — the controller does HTTP, the model does Trust & Safety.
+
+### `Moderate::Notice` — the model (does the real work)
+
+`Moderate::Notice` is **not a fourth table**. It's a thin, kind-scoped wrapper over `moderate_reports` (the same table that backs in-app reports), distinguished by `kind: "dsa_notice"`. This is on purpose: a notice and a report share the same decision workflow, the same evidence snapshot, the same appeal window, the same transparency counters. One queue, one statement-of-reasons path, one Art. 24 aggregation — whether the flag came from a logged-in user tapping "Report" or an anonymous lawyer filling in the public form.
+
+```ruby
+# Conceptually (the real model lives in the gem; this is the contract you rely on):
+notice = Moderate::Notice.new(
+  legal_reason:     "ip_infringement",     # from the DSA taxonomy (see below)
+  content_url:      "https://yourapp.com/p/123",
+  explanation:      "This post reproduces my copyrighted photo without licence.",
+  notifier_name:    "Jane Doe",
+  notifier_email:   "jane@example.com",
+  member_state:     "ES",                   # ISO-3166 EU/EEA selector
+  good_faith:       true                    # the Art. 16(2)(d) attestation, must be checked
+)
+notice.save!     # → persisted as a moderate_reports row, kind: "dsa_notice", status: :pending
+notice.reference # => "DSA-7Q2K-9F3X"  (opaque, shown on the receipt, emailed to the notifier)
+```
+
+The model owns: validations (every required DSA field, a real email, a same-origin/`http(s)` URL check, the good-faith checkbox being true), the evidence snapshot (it tries to resolve `content_url` to a reportable record and snapshot it, so evidence survives edits/deletes), `reference` generation, and dropping into `Moderate::Report.pending` so your admins act on it exactly like any other report. It fires the `notice_received` event through `config.notify` — that's your confirmation-of-receipt to the notifier **and** your admin alert, from one hook.
+
+> [!NOTE]
+> "Confirmation of receipt without undue delay" (Art. 16(4)) is satisfied by the `notice_received` event → your mailer. The gem emits the event; you wire it to [`goodmail`](https://github.com/rameerez/goodmail) (or any mailer) once, the same way you wire `report_received`. See [Notifications](../README.md#-notifications---audit--one-hook-each).
+
+### `Moderate::NoticesController` — the controller (does HTTP only)
+
+The controller is intentionally boring. It builds a blank `Moderate::Notice` for `new`, strong-params it on `create`, runs the **Turnstile gate** and the **rate-limit** as `before_action`s, and on success redirects to the receipt. On failure it re-renders `new` with `422` and the model's validation errors — standard Rails.
+
+```ruby
+# Conceptually (lives in the gem):
+module Moderate
+  class NoticesController < Moderate::ApplicationController
+    before_action :enforce_notice_enabled!
+    before_action :throttle_notices!,  only: :create   # config.notice_rate_limit
+    before_action :verify_turnstile!,  only: :create   # config.notice_turnstile_* (no-ops if unconfigured)
+
+    def new     = (@notice = Moderate::Notice.new)
+    def show    = (@notice = Moderate::Notice.find_by!(reference: params[:id]))
+
+    def create
+      @notice = Moderate::Notice.new(notice_params)
+      if @notice.save
+        redirect_to notice_path(@notice.reference), notice: t("moderate.notices.received")
+      else
+        render :new, status: :unprocessable_entity
+      end
+    end
+
+    private
+
+    def notice_params
+      params.require(:notice).permit(
+        :legal_reason, :content_url, :explanation,
+        :notifier_name, :notifier_email, :member_state, :good_faith
+      )
+    end
+  end
+end
+```
+
+`Moderate::ApplicationController` (the engine's base) inherits from `config.notice_parent_controller.constantize` (default `"::ActionController::Base"` so it works even on API-only apps, with `protect_from_forgery` applied when available) — exactly the `config.parent_controller` indirection `api_keys` and Devise use, so you can point it at your own base controller to inherit your layout, locale-setting, etc.
+
+#### The Turnstile-gate hook
+
+A public, unauthenticated form is a spam magnet. `moderate` ships a **Cloudflare Turnstile** gate as a `before_action` that:
+
+- **No-ops when unconfigured.** If `notice_turnstile_site_key`/`secret_key` are blank, the gate is skipped entirely and the form just works (great for dev/test and for apps that gate at the edge instead).
+- **Renders the widget** in the default view when the site key is present (the view checks `Moderate.configuration.notice_turnstile_site_key.present?`).
+- **Verifies server-side** on `create` by POSTing the response token to Turnstile's `siteverify`; a failed/missing token re-renders `new` with `422` and a friendly error.
+- **Is pluggable.** Prefer hCaptcha, reCAPTCHA, or your own check? Set `config.notice_captcha_verifier = ->(controller) { ... boolean ... }` and the built-in Turnstile path steps aside.
+
+We default to Turnstile (not reCAPTCHA) because it's privacy-friendly, free, and the RailsFast house default — but the verifier is just a lambda, so you're never locked in.
+
+#### The rate-limit hook
+
+On Rails 7.2+ the controller uses the built-in `rate_limit` API; on 7.1 it falls back to a tiny cache-backed counter (`Rails.cache`, per-IP). Configure it once:
+
+```ruby
+config.notice_rate_limit = { max: 5, within: 1.hour }   # default
+config.notice_rate_limit = false                        # disable (you throttle at the edge)
+```
+
+When tripped, `create` responds `429 Too Many Requests` with a retry-after message, rendered through the same (overridable) view. Both gates are deliberately **defense in depth** and both degrade to "off" gracefully, so the form never becomes a support burden in environments where you don't need them.
+
+---
+
+## The form fields (the DSA Art. 16 contract)
+
+These are the fields the regulation requires, mirrored on the X / YouTube public forms. The default view renders exactly this set; if you eject and customize, **keep all of them** — they're what makes the notice legally valid (and they map 1:1 to the model's validations).
+
+| Field | Param | Required | Notes |
+| --- | --- | --- | --- |
+| **Legal reason** | `legal_reason` | yes | A `<select>` from the **DSA statement-of-reasons taxonomy** (see below). This is the regulator-aligned set, *not* your in-app community-report categories. |
+| **Exact URL** | `content_url` | yes | "the exact electronic location of that information" — Art. 16(2)(b). Validated as an `http(s)` URL; the model tries to resolve it to a reportable record for the evidence snapshot. |
+| **Explanation** | `explanation` | yes | The "sufficiently substantiated explanation of the reasons why the individual or entity alleges the information to be illegal" — Art. 16(2)(a). Free text. |
+| **Your name** | `notifier_name` | yes* | Art. 16(2)(c). *Optional only for notices alleging certain offences against minors, where the DSA permits anonymity — the view exposes this carve-out via a checkbox that hides the name field. |
+| **Your email** | `notifier_email` | yes | Art. 16(2)(c) — where the confirmation of receipt and the decision go. Validated as a real address. |
+| **EU member state** | `member_state` | yes | ISO-3166 `<select>` of EU/EEA states — establishes jurisdiction and routing. |
+| **Good-faith statement** | `good_faith` | yes | A checkbox attesting "the information and allegations are accurate and complete" — Art. 16(2)(d). Must be checked; the model rejects the save otherwise. |
+
+The legal-reason `<select>` is driven by a single constant so the taxonomy stays consistent across the form, the model, and the Art. 17 statement-of-reasons and Art. 24 transparency counters:
+
+```ruby
+Moderate::DSA_LEGAL_REASONS
+# => [:illegal_hate_speech, :terrorism, :csam, :ip_infringement,
+#     :data_protection, :consumer_protection, :defamation,
+#     :counterfeit, :scams_fraud, :other_illegal_content]  # regulator-aligned
+```
+
+> [!NOTE]
+> **Two taxonomies, on purpose.** The in-app **community report** categories (`:harassment`, `:spam`, …) are about *your* rules; the **DSA legal-reason** taxonomy here is about *the law*. `moderate` ships both and never conflates them — a public notice always carries a `legal_reason`, an in-app report always carries a community `category`. See [DSA & compliance](../README.md#️-dsa--app-store-compliance-out-of-the-box).
+
+---
+
+## The default view, and how to override it (the `moderate:views` generator)
+
+### Out of the box
+
+The gem ships these templates inside the engine, under `app/views/moderate/`:
+
+```
+app/views/
+├── layouts/moderate/application.html.erb   # minimal, framework-agnostic layout (CSS-var themable)
+└── moderate/notices/
+    ├── new.html.erb                        # the form
+    ├── show.html.erb                       # the receipt (reference number + "what happens next")
+    └── _form.html.erb                      # the field partial (the part you'll most want to restyle)
+```
+
+They render with no CSS framework assumed, themable via CSS custom properties (the same `:root { --moderate-* }` approach `api_keys` uses for its dashboard), and they pull every label/hint through `I18n` (`moderate.notices.*`) so you can translate without touching markup. The layout inherits nothing from your app by default; point `config.notice_parent_controller` at your own base controller (and give it a `layout`) if you'd rather the form sit inside your site chrome.
+
+### Ejecting the views
+
+When you want full control of the markup, run the generator — **the Devise move**:
+
+```bash
+rails generate moderate:views
+```
+
+That copies the engine's templates into your app:
+
+```
+      create  app/views/moderate/notices/new.html.erb
+      create  app/views/moderate/notices/show.html.erb
+      create  app/views/moderate/notices/_form.html.erb
+      create  app/views/layouts/moderate/application.html.erb
+```
+
+Now edit them freely. Because your `app/views` outranks the engine in Rails' view lookup, your copies **shadow** the gem's automatically — no config, no registration. Delete a file and the gem's default for that template comes back. Upgrade the gem and your ejected copies are untouched (you re-run the generator only if you *want* the new defaults).
+
+Scope it if you only want some templates:
+
+```bash
+rails generate moderate:views --views form          # just _form.html.erb
+rails generate moderate:views --views form layout    # the form + the layout
+```
+
+The generator itself is the boring, idiomatic Rails thing — a `Rails::Generators::Base` that copies from the engine's `app/views` into the host's `app/views`, mirroring `Devise::Generators::ViewsGenerator` and `api_keys`'s install generator:
+
+```ruby
+# lib/generators/moderate/views_generator.rb (lives in the gem)
+module Moderate
+  module Generators
+    class ViewsGenerator < Rails::Generators::Base
+      source_root File.expand_path("../../../app/views", __dir__)
+
+      class_option :views, type: :array, default: %w[notices layout],
+                   desc: "Which view groups to copy (notices, form, layout)"
+
+      def copy_views
+        directory "moderate/notices", "app/views/moderate/notices"   if include?("notices")
+        copy_file "moderate/notices/_form.html.erb",
+                  "app/views/moderate/notices/_form.html.erb"        if include?("form")
+        directory "layouts/moderate", "app/views/layouts/moderate"   if include?("layout")
+      end
+    end
+  end
+end
+```
+
+> [!TIP]
+> Generator naming follows the ecosystem: `moderate:install` (migration + initializer, like every other gem) and `moderate:views` (eject the form, like Devise). Nothing else is generated — we do **not** ship admin-view generators, because admin is BYOUI.
+
+---
+
+## Staying optional: ignore the engine entirely
+
+The engine is a courtesy, not a contract. If you want to build the public notice page yourself — your own route, your own controller, your own styling — **don't mount it**, and talk to the model directly:
+
+```ruby
+class LegalController < ApplicationController
+  def new_notice  = (@notice = Moderate::Notice.new)
+
+  def create_notice
+    @notice = Moderate::Notice.new(notice_params)
+    if @notice.save
+      # your own confirmation page / mailer
+    else
+      render :new_notice, status: :unprocessable_entity
+    end
+  end
+end
+```
+
+You still get every Art. 16 validation, the evidence snapshot, the `reference`, the `notice_received` event, and the row landing in `Moderate::Report.pending` — you just bring the HTML. Mounting the engine is the fast path; using the model directly is the full-control path. Either way the compliance lives in the model, not the view.
+
+And if you don't serve EU users at all? Skip both. Reporting, blocking, and filtering work standalone without ever touching `Moderate::Notice`.
+
+---
+
+## Configuration reference (notice form)
+
+```ruby
+Moderate.configure do |config|
+  config.notice_form_enabled        = true                  # mount-able engine on/off (default: true)
+  config.notice_parent_controller   = "::ActionController::Base"  # like Devise's config.parent_controller
+  config.notice_rate_limit          = { max: 5, within: 1.hour }  # per-IP throttle, or false to disable
+
+  # Bot gate (all optional — the gate no-ops when blank):
+  config.notice_turnstile_site_key   = ENV["TURNSTILE_SITE_KEY"]
+  config.notice_turnstile_secret_key = ENV["TURNSTILE_SECRET_KEY"]
+  config.notice_captcha_verifier     = nil                  # ->(controller) { boolean } to swap Turnstile out
+end
+```
+
+Every one of these has a sensible default, so `mount Moderate::Engine => "/legal"` with an otherwise-empty config gives you a working, compliant form. See the [main configuration reference](../README.md#configuration-reference) for the rest of `moderate`.

+# Admin & the moderation queue — wiring `moderate` into `madmin` (BYOUI)
+
+Most of Trust & Safety lives in *admin*: a human (or a script) looking at a queue of reports, flags, and appeals and making a call. `moderate` deliberately does **not** ship admin chrome — it ships the **primitives** (the `Moderate::Report` / `Moderate::Flag` / `Moderate::Appeal` / `Moderate::Block` models, the `resolve!` / `dismiss!` / `uphold!` / `reject!` decision methods, the queue scopes, the controller concern), and lets you **bring your own UI**.
+
+This guide is the full walkthrough for the most common BYOUI choice: [`madmin`](https://github.com/excid3/madmin). It's the exact recipe a real production app uses, distilled. If you're on ActiveAdmin, Avo, Trestle, or a hand-rolled admin, the *shape* is identical — generate a screen against the model, add two buttons, POST to a custom action that calls the gem's decision method. Only the framework glue changes.
+
+> [!NOTE]
+> Why no built-in admin? Trust & Safety UI is the part every app wants to own — your branding, your auth, your layout, your extra columns. The decision *logic* (atomic content removal, ban, notify, audit) is the part nobody should reimplement. `moderate` draws the line exactly there: the gem owns the `resolve!`/`dismiss!`/`uphold!`/`reject!` transaction; you own the screen that calls it. See [What `moderate` does and doesn't do](../README.md#what-moderate-does-and-doesnt-do).
+
+---
+
+## TL;DR
+
+```bash
+# 1. Generate one madmin resource per moderation model
+rails generate madmin:resource Moderate::Report
+rails generate madmin:resource Moderate::Flag
+rails generate madmin:resource Moderate::Appeal
+rails generate madmin:resource Moderate::Block
+```
+
+```ruby
+# 2. Add member routes for the decisions (config/routes.rb, inside your madmin namespace)
+resources :reports, only: [:index, :show] do
+  member { post :resolve; post :dismiss }
+end
+resources :flags, only: [:index, :show] do
+  member { post :resolve; post :dismiss }
+end
+resources :appeals, only: [:index, :show] do
+  member { post :uphold; post :reject }
+end
+resources :blocks, only: [:index, :show]
+```
+
+```ruby
+# 3. Subclass the madmin resource controller and call the gem's decision methods
+module Madmin
+  class ReportsController < Madmin::ResourceController
+    def resolve
+      @record.resolve!(by: current_user, remove_content: params[:remove_content],
+                       ban_user: params[:ban_user], note: params[:note])
+      redirect_to main_app.madmin_report_path(@record), notice: "Report resolved.", status: :see_other
+    rescue => e
+      redirect_to main_app.madmin_report_path(@record), alert: "Could not resolve: #{e.message}", status: :see_other
+    end
+
+    def dismiss
+      @record.dismiss!(by: current_user, note: params[:note])
+      redirect_to main_app.madmin_report_path(@record), notice: "Report dismissed.", status: :see_other
+    rescue => e
+      redirect_to main_app.madmin_report_path(@record), alert: "Could not dismiss: #{e.message}", status: :see_other
+    end
+  end
+end
+```
+
+That's the whole pattern. The rest of this doc fills in the resource definitions, the queue, the decision buttons, and the gotchas.
+
+---
+
+## The model primitives `madmin` points at
+
+`moderate`'s models are **plain ActiveRecord**, so they show up in `madmin` like any other model — no special integration. Here's what you're admining and the queue scope on each:
+
+| Model | What it is | The queue scope | Decide with |
+| --- | --- | --- | --- |
+| `Moderate::Report` | In-app reports **and** public DSA notices (one table, distinguished by `kind`) | `Moderate::Report.pending` | `report.resolve!` / `report.dismiss!` |
+| `Moderate::Flag` | Auto-filter flags from `:flag`-mode `moderates` (source: `wordlist` / `image` / a remote adapter / `manual`) | `Moderate::Flag.pending` | `flag.resolve!` / `flag.dismiss!` |
+| `Moderate::Appeal` | DSA Art. 20 internal complaints against a decision | `Moderate::Appeal.pending` | `appeal.uphold!` / `appeal.reject!` |
+| `Moderate::Block` | The bidirectional `blocker`/`blocked` safety edge | (no decision — read-only) | n/a |
+
+The same `pending` scope is what a **human admin** reads in `madmin` *and* what an **automated ML consumer** reads in a background job — one queue, two readers. (More on that in [Automated review](#automated-review-the-same-pending-queue).)
+
+> [!IMPORTANT]
+> Decisions are **only** ever made by calling the gem's methods (`resolve!`, `dismiss!`, `uphold!`, `reject!`). Don't let madmin's stock edit form mutate `status` directly. Every decision is atomic, requires a moderator + a note, runs your enforcement (content removal via the reportable's own `remove_reported_field!`, bans via your `ban_handler`), fires the `notify` / `audit` hooks, and stamps the appeal window. A raw `status = "resolved"` update skips all of that and leaves you non-compliant. Keep the models **read-only** in madmin (`form: false`) and route every change through a custom member action — exactly what this guide does.
+
+---
+
+## Step 1 — Generate the resources
+
+`madmin`'s generator works against namespaced models out of the box:
+
+```bash
+rails generate madmin:resource Moderate::Report
+rails generate madmin:resource Moderate::Flag
+rails generate madmin:resource Moderate::Appeal
+rails generate madmin:resource Moderate::Block
+```
+
+Each creates `app/madmin/resources/moderate/<model>_resource.rb` and a flat controller stub. Now edit the resources to make them a real moderation queue — read-only columns, queue scopes, and a useful index order.
+
+### `Moderate::ReportResource`
+
+```ruby
+# app/madmin/resources/moderate/report_resource.rb
+class Moderate::ReportResource < Madmin::Resource
+  model Moderate::Report
+
+  # Everything is read-only (form: false): decisions go through the custom
+  # member actions below, never through madmin's stock edit form.
+  attribute :id,          index: true, form: false
+  attribute :status,      index: true, form: false   # pending / resolved / dismissed
+  attribute :kind,        index: true, form: false   # "report" (in-app) or "dsa_notice"
+  attribute :category,    index: true, form: false   # community category OR DSA legal_reason
+  attribute :reportable,  :polymorphic, index: true, form: false, label: "Target"
+  attribute :reported_field, index: true, form: false, label: "Field"
+  attribute :reported_user,  index: true, form: false
+  attribute :reporter,       index: true, form: false
+  attribute :notifier_email, index: true, form: false, label: "Notifier"  # DSA notices
+  attribute :details,        index: false, form: false
+  attribute :snapshot,       index: false, form: false   # the immutable evidence snapshot
+  attribute :resolution_note, index: false, form: false
+  attribute :created_at,  index: true, form: false, label: "Received"
+  attribute :resolved_at, index: true, form: false
+
+  # Queue scopes — these are the gem's own scopes, surfaced as madmin filters.
+  scope :pending
+  scope :resolved
+  scope :dismissed
+
+  menu label: "Reports", parent: "Trust & Safety"
+
+  def self.display_name(record) = "Report ##{record.id.to_s.first(8)}"
+  def self.default_sort_column = "created_at"
+  def self.default_sort_direction = "desc"
+end
+```
+
+### `Moderate::FlagResource`
+
+```ruby
+# app/madmin/resources/moderate/flag_resource.rb
+class Moderate::FlagResource < Madmin::Resource
+  model Moderate::Flag
+
+  attribute :id,         index: true, form: false
+  attribute :status,     index: true, form: false   # pending / resolved / dismissed
+  attribute :source,     index: true, form: false   # wordlist / image / <your adapter> / manual
+  attribute :flaggable,  :polymorphic, index: true, form: false, label: "Target"
+  attribute :field,      index: true, form: false
+  attribute :owner,      index: true, form: false
+  attribute :categories, index: false, form: false  # e.g. [:hate, :threats]
+  attribute :scores,     index: false, form: false  # { hate: 1.0 } (0..1 for ML adapters)
+  attribute :resolution_note, index: false, form: false
+  attribute :created_at, index: true, form: false
+  attribute :reviewed_at, index: true, form: false
+
+  scope :pending
+  scope :resolved
+  scope :dismissed
+
+  menu label: "Flags", parent: "Trust & Safety"
+
+  def self.display_name(record) = "Flag ##{record.id.to_s.first(8)}"
+  def self.default_sort_column = "created_at"
+  def self.default_sort_direction = "desc"
+end
+```
+
+### `Moderate::AppealResource`
+
+```ruby
+# app/madmin/resources/moderate/appeal_resource.rb
+class Moderate::AppealResource < Madmin::Resource
+  model Moderate::Appeal
+
+  attribute :id,     index: true, form: false
+  attribute :status, index: true, form: false   # pending / upheld / rejected
+  attribute :report, index: true, form: false   # the decision being appealed
+  attribute :appellant_email, index: true, form: false
+  attribute :reason, index: false, form: false
+  attribute :resolution_note, index: false, form: false
+  attribute :created_at,  index: true, form: false, label: "Received"
+  attribute :resolved_at, index: true, form: false
+
+  scope :pending
+  scope :upheld
+  scope :rejected
+
+  menu label: "Appeals", parent: "Trust & Safety"
+
+  def self.display_name(record) = "Appeal ##{record.id.to_s.first(8)}"
+  def self.default_sort_column = "created_at"
+  def self.default_sort_direction = "desc"
+end
+```
+
+### `Moderate::BlockResource` (read-only)
+
+Blocks have no decision — they're a user safety edge, so they're a plain read-only list for support visibility:
+
+```ruby
+# app/madmin/resources/moderate/block_resource.rb
+class Moderate::BlockResource < Madmin::Resource
+  model Moderate::Block
+
+  attribute :id,      index: true, form: false
+  attribute :blocker, index: true, form: false
+  attribute :blocked, index: true, form: false
+  attribute :created_at, index: true, form: false
+
+  menu label: "Blocks", parent: "Trust & Safety"
+
+  def self.display_name(record) = "Block ##{record.id.to_s.first(8)}"
+end
+```
+
+> [!TIP]
+> Group all four under one `parent:` (here `"Trust & Safety"`) so they sit together in the madmin sidebar — that grouping *is* your moderation queue's navigation.
+
+---
+
+## Step 2 — Routes for the decisions
+
+`madmin` gives you `index`/`show` for free. The decisions are custom **member** actions you add yourself, the standard Rails way. Inside your madmin namespace:
+
+```ruby
+# config/routes.rb
+namespace :madmin do
+  resources :reports, only: [:index, :show] do
+    member do
+      post :resolve
+      post :dismiss
+    end
+  end
+
+  resources :flags, only: [:index, :show] do
+    member do
+      post :resolve
+      post :dismiss
+    end
+  end
+
+  resources :appeals, only: [:index, :show] do
+    member do
+      post :uphold
+      post :reject
+    end
+  end
+
+  resources :blocks, only: [:index, :show]   # read-only
+end
+```
+
+This gives you `resolve_madmin_report_path(report)`, `dismiss_madmin_report_path(report)`, `uphold_madmin_appeal_path(appeal)`, and friends — the URLs your decision buttons POST to.
+
+> [!NOTE]
+> Keep `only: [:index, :show]`. There's no `:edit`/`:update`/`:destroy` because **the only legitimate way to change a moderation record is a decision method**, and those live behind the member actions, not the stock REST update.
+
+---
+
+## Step 3 — The controller (call the gem's decision methods)
+
+This is the heart of the integration, and it's tiny. Subclass `Madmin::ResourceController`, add one action per decision, and have each action call the matching `moderate` method. `@record` is set for you by `madmin` (it's the report/flag/appeal the member route resolved).
+
+```ruby
+# app/controllers/madmin/reports_controller.rb
+module Madmin
+  class ReportsController < Madmin::ResourceController
+    def resolve
+      @record.resolve!(
+        by:             current_user,                 # the moderator (required)
+        remove_content: params[:remove_content],       # runs reportable#remove_reported_field!
+        ban_user:       params[:ban_user],             # runs your config.ban_handler
+        note:           params[:note]                  # required — the decision rationale
+      )
+      redirect_to main_app.madmin_report_path(@record),
+        notice: "Report resolved.", status: :see_other
+    rescue => error
+      redirect_to main_app.madmin_report_path(@record),
+        alert: "Could not resolve report: #{error.message}", status: :see_other
+    end
+
+    def dismiss
+      @record.dismiss!(by: current_user, note: params[:note])
+      redirect_to main_app.madmin_report_path(@record),
+        notice: "Report dismissed.", status: :see_other
+    rescue => error
+      redirect_to main_app.madmin_report_path(@record),
+        alert: "Could not dismiss report: #{error.message}", status: :see_other
+    end
+
+    private
+
+    # Eager-load the associations the index/show touch, so the queue page
+    # doesn't N+1 across reporter / reported_user / target.
+    def scoped_resources
+      super.includes(:reporter, :reported_user, :reportable)
+    end
+  end
+end
+```
+
+```ruby
+# app/controllers/madmin/flags_controller.rb
+module Madmin
+  class FlagsController < Madmin::ResourceController
+    def resolve
+      @record.resolve!(by: current_user, note: params[:note])
+      redirect_to main_app.madmin_flag_path(@record), notice: "Flag actioned.", status: :see_other
+    rescue => error
+      redirect_to main_app.madmin_flag_path(@record), alert: "Could not action flag: #{error.message}", status: :see_other
+    end
+
+    def dismiss
+      @record.dismiss!(by: current_user, note: params[:note])
+      redirect_to main_app.madmin_flag_path(@record), notice: "Flag dismissed.", status: :see_other
+    rescue => error
+      redirect_to main_app.madmin_flag_path(@record), alert: "Could not dismiss flag: #{error.message}", status: :see_other
+    end
+
+    private
+
+    def scoped_resources
+      super.includes(:flaggable, :owner)
+    end
+  end
+end
+```
+
+```ruby
+# app/controllers/madmin/appeals_controller.rb
+module Madmin
+  class AppealsController < Madmin::ResourceController
+    def uphold
+      @record.uphold!(by: current_user, note: params[:note])   # overturns the original decision
+      redirect_to main_app.madmin_appeal_path(@record), notice: "Appeal upheld.", status: :see_other
+    rescue => error
+      redirect_to main_app.madmin_appeal_path(@record), alert: "Could not uphold appeal: #{error.message}", status: :see_other
+    end
+
+    def reject
+      @record.reject!(by: current_user, note: params[:note])   # confirms the original decision
+      redirect_to main_app.madmin_appeal_path(@record), notice: "Appeal rejected.", status: :see_other
+    rescue => error
+      redirect_to main_app.madmin_appeal_path(@record), alert: "Could not reject appeal: #{error.message}", status: :see_other
+    end
+
+    private
+
+    def scoped_resources
+      super.includes(:report, :appellant)
+    end
+  end
+end
+```
+
+Notice what's **not** here: no content-removal SQL, no `user.suspend!`, no email sending, no audit write. All of that is the gem's job, triggered atomically inside `resolve!` / `dismiss!` / `uphold!` / `reject!`. Your controller is pure HTTP — params in, decision method called, redirect out. (That's why every action is a four-liner with a `rescue` for the flash.)
+
+> [!IMPORTANT]
+> Use `status: :see_other` on the redirects. The decision actions are `POST`s, and Turbo needs a 303 to follow a redirect after a non-GET. This is the same convention madmin's own create/update use.
+
+### Reuse from the standard `Moderate::Moderation` concern instead
+
+If you'd rather not hand-write the four controllers, `moderate` ships a controller concern that gives you the `resolve`/`dismiss` (and appeal `uphold`/`reject`) actions, strong params, and redirects already wired — you just bring auth:
+
+```ruby
+module Madmin
+  class ReportsController < Madmin::ResourceController
+    include Moderate::Moderation   # resolve!/dismiss! actions, strong params, redirects
+  end
+end
+```
+
+Hand-rolling (above) is the right call when your redirects/flashes need to match the rest of your madmin app; the concern is the right call when you want zero boilerplate. They do the same thing.
+
+---
+
+## Step 4 — The decision buttons (the show view)
+
+`madmin`'s stock `show` template lists attributes; add a small panel with the decision forms. The cleanest move is a custom show view at `app/views/madmin/reports/show.html.erb` that renders madmin's default attributes and then a "Decide" sidebar. The load-bearing part is just two forms that POST to the member routes — render them only while the record is still `pending`:
+
+```erb
+<%# app/views/madmin/reports/show.html.erb (decision panel; render alongside madmin's default attribute list) %>
+<% report = @record %>
+
+<% if report.pending? %>
+  <section>
+    <h2>Resolve</h2>
+    <%= form_with url: resolve_madmin_report_path(report), method: :post do %>
+      <label><%= check_box_tag :remove_content, "1" %> Remove reported content</label>
+      <label><%= check_box_tag :ban_user, "1" %> Ban reported user</label>
+      <%= text_area_tag :note, nil, placeholder: "Decision note", required: true %>
+      <%= submit_tag "Resolve", data: { turbo_confirm: "Resolve and notify the parties?" } %>
+    <% end %>
+
+    <h2>Dismiss</h2>
+    <%= form_with url: dismiss_madmin_report_path(report), method: :post do %>
+      <%= text_area_tag :note, nil, placeholder: "Decision note", required: true %>
+      <%= submit_tag "Dismiss", data: { turbo_confirm: "Dismiss and notify the reporter?" } %>
+    <% end %>
+  </section>
+<% else %>
+  <p>This report is closed.</p>
+<% end %>
+```
+
+The appeal show view is the same shape with `uphold`/`reject`:
+
+```erb
+<% appeal = @record %>
+<% if appeal.pending? %>
+  <%= form_with url: uphold_madmin_appeal_path(appeal), method: :post do %>
+    <%= text_area_tag :note, nil, placeholder: "Why the original decision is overturned", required: true %>
+    <%= submit_tag "Uphold appeal", data: { turbo_confirm: "Overturn the original decision?" } %>
+  <% end %>
+  <%= form_with url: reject_madmin_appeal_path(appeal), method: :post do %>
+    <%= text_area_tag :note, nil, placeholder: "Why the original decision stands", required: true %>
+    <%= submit_tag "Reject appeal", data: { turbo_confirm: "Confirm the original decision?" } %>
+  <% end %>
+<% end %>
+```
+
+Two details worth copying:
+
+- **Gate on `pending?`.** Show the decision forms only while the record is open; render "closed" once it isn't. The decision methods are also guarded server-side (calling `resolve!` on an already-resolved report raises), but hiding the buttons is the better UX.
+- **Require the note.** `required: true` on the textarea, and the gem requires it too — every decision must carry a rationale (that's what feeds the DSA Art. 17 statement of reasons). Belt and suspenders.
+
+The evidence snapshot (`report.snapshot`) is plain JSON on the record — render it in a `<pre>` so the moderator sees exactly what was reported, even if the original content was since edited or deleted. That immutability is the whole point of the snapshot.
+
+---
+
+## The moderation-queue pattern (the index)
+
+Your `index` *is* the queue. Three things make it usable:
+
+1. **Default to pending.** The `scope :pending` you declared on each resource gives madmin a one-click filter; make it the landing view by sorting `created_at desc` and pointing your "Moderation" nav link at `madmin_reports_path(scope: :pending)`.
+2. **One sidebar group.** All four resources under one `parent:` menu (`"Trust & Safety"`) so reports, flags, appeals, and blocks read as a single workspace.
+3. **A queue-depth dashboard tile.** The same scopes power an at-a-glance count on your admin home:
+
+```ruby
+# app/controllers/madmin/dashboard_controller.rb
+def show
+  @pending_reports = Moderate::Report.pending.count
+  @pending_flags   = Moderate::Flag.pending.count
+  @pending_appeals = Moderate::Appeal.pending.count
+end
+```
+
+```erb
+<%= link_to "#{@pending_reports} reports awaiting review", madmin_reports_path(scope: :pending) %>
+<%= link_to "#{@pending_flags} flags awaiting review",     madmin_flags_path(scope: :pending) %>
+<%= link_to "#{@pending_appeals} appeals awaiting review", madmin_appeals_path(scope: :pending) %>
+```
+
+That's the whole moderation queue: pending-first lists, grouped nav, and a count on the dashboard — all built from the gem's `pending` scopes and your existing madmin.
+
+---
+
+## Automated review: the same `pending` queue
+
+The headline trick of the model design: **a human admin and an ML/automation consumer read the *same* `Moderate::Flag.pending` (or `Moderate::Report.pending`) scope.** Your madmin screen is one reader; a background job is another. To auto-action high-confidence flags before a human ever sees them, drain the same queue in a job and call the same decision method:
+
+```ruby
+class AutoModerationJob < ApplicationJob
+  def perform
+    Moderate::Flag.pending.find_each do |flag|
+      next unless flag.scores[:csam].to_f >= 0.99   # only the unambiguous ones
+      flag.resolve!(by: Moderate.system_actor, note: "Auto-removed: high-confidence CSAM")
+    end
+  end
+end
+```
+
+Because the job calls `resolve!` (not a raw `update`), the auto-decision is identical to a human one — atomic enforcement, `notify`/`audit` hooks, statement-of-reasons, appeal window. Whatever the job doesn't touch stays in `pending` for a human in madmin. One queue, two consumers, zero divergence.
+

+
+## What `moderate` ships vs. what you build
+
+To be explicit about the boundary this guide sits on:
+
+| `moderate` ships (the primitives) | You build (the UI chrome) |
+| --- | --- |
+| The models (`Report`/`Flag`/`Appeal`/`Block`) | The madmin resources (columns, labels, fields) |
+| The queue scopes (`.pending`, `.resolved`, …) | The index/show screens & nav grouping |
+| The decision methods (`resolve!`/`dismiss!`/`uphold!`/`reject!`) — atomic enforcement + notify + audit + appeal window | The buttons/forms that call them |
+| The optional `Moderate::Moderation` controller concern | Auth (`current_user`, admin gate) |
+| Helpers + the evidence snapshot on each record | Your branding, layout, extra columns |
+
+You wire it once and you have a real, compliant moderation queue, in your own admin, in an afternoon.

+# Notifications — wire email, in-app, and admin alerts once
+
+`moderate` never sends an email, never posts to Telegram, never writes a push. It does exactly one thing with notifications: it **emits events**. You wire those events to wherever they should go — **once** — and everything downstream (a report receipt, a decision email, an admin "🚩 new flag" ping, an in-app feed item) flows from that single hook.
+
+That hook is `config.notify`:
+
+```ruby
+Moderate.configure do |config|
+  config.notify = ->(event) { ... }   # called for every notifiable event; no-op by default
+end
+```
+
+One lambda. Every notifiable thing that happens in your Trust & Safety layer passes through it. Inside it you `case` on `event.name` and fan out to:
+
+- **[`goodmail`](https://github.com/rameerez/goodmail)** — beautiful transactional **emails** to the *user* (report receipt, decision / statement-of-reasons, appeal outcome).
+- **[`telegrama`](https://github.com/rameerez/telegrama)** — a one-line Telegram **admin alert** (a new report landed, content got auto-flagged, a DSA notice arrived).
+- **[`noticed`](https://github.com/excid3/noticed)** — multi-channel **in-app feed + push** to the user.
+
+The whole point: **notify users by email and in-app, AND optionally ping yourself on Telegram, all wired in one place.** No notification logic scattered across your models, services, and controllers — `moderate` collects every moment worth telling someone about and hands them to you with a stable envelope.
+
+> [!NOTE]
+> `config.notify` is for **people** (users get emails/push, admins get a Telegram nudge). It's separate from `config.audit`, which is for **machines** (append-only record of every action for your audit log). Same envelope, different intent — see [Audit](#audit-the-other-hook) at the bottom. Most apps wire both, in the same initializer, in about fifteen lines.
+
+---
+
+## TL;DR — the one recipe
+
+```ruby
+# config/initializers/moderate.rb
+Moderate.configure do |config|
+  config.notify = ->(event) do
+    # 1) Email the user (goodmail) — receipts, decisions, statements of reasons.
+    case event.name
+    when :report_received, :report_decision, :affected_user_decision,
+         :appeal_received, :appeal_decision, :notice_received
+      Array(event.recipients).each do |user|
+        next unless user.respond_to?(:email)   # anonymous DSA notifiers carry an email, not a User
+        ModerationMailer.with(event: event, recipient: user)
+                        .public_send(event.name)
+                        .deliver_later
+      end
+    end
+
+    # 2) Ping admins on Telegram (telegrama) — ONE message, only for things YOU care about.
+    case event.name
+    when :report_received, :notice_received, :content_flagged
+      Telegrama.send_message(event.payload[:summary], formatting: { obfuscate_emails: true })
+    end
+
+    # 3) In-app feed + push (noticed) — the user's bell icon and device.
+    case event.name
+    when :report_decision, :affected_user_decision, :appeal_decision,
+         :user_banned, :content_removed
+      Moderate::DecisionNotifier.with(event: event).deliver(event.recipients)
+    end
+  end
+end
+```
+
+That's the entire integration. Three `case`s, one per channel, in one lambda. Add or drop an `event.name` from any list to turn a channel on/off for that moment. The rest of this doc explains the envelope, the full vocabulary, and each channel in detail.
+
+> [!IMPORTANT]
+> **Keep `config.notify` fast.** It runs inside the same call as the moderation action (often inside a transaction). Always hand off to a background job — `deliver_later` (goodmail / Action Mailer), `perform_later` (your own jobs), or `Telegrama`'s async mode (below). Never do blocking HTTP in the hook itself.
+
+---
+
+## The event envelope
+
+Every event your `notify` hook receives is the same small, stable object. You never construct it — `moderate` does — you only read it:
+
+```ruby
+event.name        # Symbol — which moment this is, e.g. :report_decision (the full list below)
+event.subject     # the record this is about — a Moderate::Report / Flag / Block / Appeal / Notice
+event.actor       # who triggered it — a moderator, a user, or nil for system/automated events
+event.recipients  # Array of who should be told — usually the user(s) to email/notify
+event.payload     # Hash of event-specific context, ALWAYS including :summary (a ready-to-send line)
+event.to_h        # the whole envelope as a Hash (handy for logging, tests, and noticed params)
+```
+
+Two fields do most of the work:
+
+- **`event.recipients`** — already resolved to *the right people* for this event. For `report_received` it's the reporter (their receipt). For `report_decision` it's the reporter (the outcome). For `affected_user_decision` it's the person whose content/account was acted on (their statement of reasons). You don't compute audiences — `moderate` does, and hands you the array. Iterate it.
+- **`event.payload[:summary]`** — a short, human, already-redaction-safe one-liner describing what happened (e.g. `"New harassment report on Comment #4213 by joh…e@example.com"`). It exists so your **admin Telegram ping is literally one line** — no string-building, no leaking. Everything richer (the model, the category, the moderator's note) is also in `payload` if you want to compose your own copy.
+
+A recipient is usually one of your `User` records (it responds to `email`, `id`, etc.), **except** for DSA-notice events (`notice_received`, and the `affected_user_decision` for a public notice) where the notifier may be an anonymous person — there `moderate` gives you a lightweight recipient that responds to `email`/`name` but is **not** a `User`. The `next unless user.respond_to?(:email)` / `user.is_a?(User)` guards in the recipes above handle that cleanly.
+
+---
+
+## The full event vocabulary
+
+These are every event `moderate` can emit. Wire the ones you care about; ignore the rest (the hook is a plain `case` — unmatched names just fall through).
+
+| Event | When it fires | `actor` | `recipients` | Typical channels |
+| --- | --- | --- | --- | --- |
+| `report_received` | A user files an in-app report | the reporter | the reporter (receipt) | 📧 user receipt · 💬 admin ping |
+| `notice_received` | A public **DSA Art. 16** notice is submitted | the notifier (may be anonymous) | the notifier (Art. 16(4) confirmation of receipt) | 📧 confirmation · 💬 admin ping |
+| `report_decision` | A moderator resolves/dismisses a report | the moderator | the reporter (outcome) | 📧 email · 🔔 in-app |
+| `affected_user_decision` | A decision affects the reported party | the moderator | the reported user / notice subject (**statement of reasons**, Art. 17) | 📧 email · 🔔 in-app |
+| `appeal_received` | A user appeals a decision (Art. 20) | the appellant | the appellant (receipt) | 📧 receipt · 💬 admin ping |
+| `appeal_decision` | A moderator upholds/rejects an appeal | the moderator | the appellant | 📧 email · 🔔 in-app |
+| `user_blocked` | One user blocks another | the blocker | — *(usually silent; no recipients)* | 🔕 audit only, typically |
+| `user_unblocked` | A block is lifted | the blocker | — | 🔕 audit only, typically |
+| `user_banned` | A user is banned (your `ban_handler` ran) | the moderator | the banned user | 📧 email · 🔔 in-app |
+| `content_flagged` | The filter auto-creates a `Moderate::Flag` (`:flag` mode) | nil (system) | — *(no user; it's a queue item)* | 💬 admin ping |
+| `content_removed` | Content is removed (via `remove_reported_field!`) | the moderator | the content's owner | 📧 email · 🔔 in-app |
+
+A few notes that save you grief:
+
+- **`content_flagged` has no user recipient.** It's the system telling *admins* "something needs a look" — there's nothing to email the author. Route it to Telegram (and/or your moderation dashboard), not to a user mailer. Its `recipients` is empty by design.
+- **`report_decision` vs `affected_user_decision` are two events on purpose.** The same resolution tells the *reporter* "we handled your report" (one tone) and the *reported party* "here's what we did and why, and how to appeal" (the DSA Art. 17 statement of reasons — a different tone, different legal weight). Two events let you send two different emails from one moderator click.
+- **Blocks are usually silent.** You rarely email "you've been blocked" (it invites retaliation). `user_blocked` / `user_unblocked` exist mostly for `config.audit`, but they're here in `notify` too if your product wants an in-app signal.
+
+---
+
+## Channel 1 — Email the user with [`goodmail`](https://github.com/rameerez/goodmail)
+
+Receipts, decisions, and statements of reasons are exactly what `goodmail` is for: clean, single-template transactional email with zero HTML hell. Build one mailer keyed by event name and let `config.notify` call it.
+
+```ruby
+# config/initializers/moderate.rb
+config.notify = ->(event) do
+  case event.name
+  when :report_received, :report_decision, :affected_user_decision,
+       :appeal_received, :appeal_decision, :notice_received, :user_banned, :content_removed
+    Array(event.recipients).each do |recipient|
+      next unless recipient.respond_to?(:email) && recipient.email.present?
+      ModerationMailer.with(event: event, recipient: recipient)
+                      .public_send(event.name)
+                      .deliver_later
+    end
+  end
+end
+```
+
+```ruby
+# app/mailers/moderation_mailer.rb
+class ModerationMailer < ApplicationMailer
+  # `event` and `recipient` arrive via `.with(...)` and are available as `params[:event]` / `params[:recipient]`.
+
+  def report_received
+    event = params[:event]
+    goodmail_mail(to: params[:recipient].email, from: "trust@myapp.com",
+                  subject: "We received your report") do
+      h1 "Thanks — we're on it"
+      text "We received your report and our team is reviewing it. You don't need to do anything else."
+      info_row "Reference", event.subject.reference
+      info_row "Filed",     event.subject.created_at.to_date.to_s
+      sign
+    end
+  end
+
+  def affected_user_decision
+    event = params[:event]
+    # DSA Art. 17 statement of reasons: action taken, the ground, automated-means flag, redress path.
+    goodmail_mail(to: params[:recipient].email, from: "trust@myapp.com",
+                  subject: "An update about your content") do
+      h1 "We took action on your content"
+      text event.payload[:reason]                       # the human-readable ground
+      info_row "Action",          event.payload[:action]        # e.g. "Content removed"
+      info_row "Automated means", event.payload[:automated] ? "Yes" : "No"
+      space
+      text "If you believe this was a mistake, you can appeal — it's free and reviewed by a person."
+      button "Appeal this decision", event.payload[:appeal_url] # moderate mints a signed link for you
+      sign
+    end
+  end
+
+  def notice_received
+    event = params[:event]
+    goodmail_mail(to: params[:recipient].email, from: "legal@myapp.com",
+                  subject: "Confirmation of your notice") do
+      h1 "We received your notice"
+      text "This confirms receipt of your notice under Article 16 of the Digital Services Act."
+      info_row "Reference", event.subject.reference
+      sign
+    end
+  end
+end
+```
+
+Why this shape:
+
+- **`.with(event:, recipient:)`** is the standard Action Mailer params path, so the same arguments survive `deliver_later` serialization (the event's records are GlobalID-serializable AR objects).
+- **`public_send(event.name)`** lets the *event name* select the mailer action — `report_received` → `#report_received` — so adding a new email is "add a method," not "add a branch."
+- **`goodmail_mail`** is goodmail's mailer helper: it renders the DSL block, wires `List-Unsubscribe`, and hands a normal multipart message to Action Mailer. Use its DSL (`h1`, `text`, `info_row`, `button`, `sign`, …) instead of ERB templates. `info_row`/`price_row` are perfect for the reference/date/action rows a decision email needs.
+- **The appeal link** in a decision email is the signed link `moderate` mints for you (`config.signed_gid_purposes` includes `:appeal`); read it from `event.payload[:appeal_url]` rather than building your own route.
+
+> [!TIP]
+> Per-product or per-tenant branding? `goodmail_mail` accepts `config: { company_name:, brand_color:, logo_url: }` for a scoped, thread-local override — handy if your app is white-labeled. See goodmail's "Per-message branding."
+
+---
+
+## Channel 2 — Ping admins on Telegram with [`telegrama`](https://github.com/rameerez/telegrama)
+
+This is the "tell *me* something happened" channel. `event.payload[:summary]` is built for it — a single, safe line — so the admin ping is genuinely one call:
+
+```ruby
+config.notify = ->(event) do
+  case event.name
+  when :report_received, :notice_received, :content_flagged, :appeal_received
+    Telegrama.send_message(event.payload[:summary], formatting: { obfuscate_emails: true })
+  end
+end
+```
+
+That's it. `event.payload[:summary]` for `content_flagged` reads like:
+
+> 🚩 Auto-flagged Message #8821 — categories: hate, threats
+
+and for `report_received`:
+
+> 🚩 New harassment report on Comment #4213 by joh…e@example.com
+
+`obfuscate_emails: true` means even if a summary or your own copy contains a user's address, telegrama redacts it (`john.doe@x.com` → `joh…e@x.com`) before it hits a shared admin chat. Turn it on for anything touching user PII.
+
+### Compose a richer alert when you want one
+
+The `summary` is the fast path. When you'd rather build the message (the way you'd alert a sale), reach into `event.payload` and use telegrama's MarkdownV2 formatting:
+
+```ruby
+when :report_received
+  report = event.subject
+  msg = <<~MSG
+    🚩 *New report*
+
+    *Category:* #{report.category}
+    *On:* #{report.reportable_label}
+    *By:* #{event.actor&.email}
+
+    [🔗 Open in moderation queue](#{Rails.application.routes.url_helpers.admin_report_url(report)})
+  MSG
+  Telegrama.send_message(msg, formatting: { obfuscate_emails: true })
+```
+
+### Route different alerts to different chats / topics
+
+Got separate Telegram chats (or forum topics) for "trust & safety" vs "everything else"? telegrama takes `chat_id:` and `message_thread_id:` per message:
+
+```ruby
+TRUST_CHAT  = Rails.application.credentials.dig(:telegram, :trust_chat_id)
+TRUST_TOPIC = Rails.application.credentials.dig(:telegram, :trust_topic_id)
+
+when :content_flagged, :notice_received
+  Telegrama.send_message(event.payload[:summary],
+                         chat_id: TRUST_CHAT,
+                         message_thread_id: TRUST_TOPIC,
+                         formatting: { obfuscate_emails: true })
+```
+
+> [!TIP]
+> Enable telegrama's **async delivery** (`config.deliver_message_async = true` in `config/initializers/telegrama.rb`) so admin pings never block a moderation action — this is the cleanest way to keep your `config.notify` hook fast for the Telegram leg. telegrama also degrades gracefully (MarkdownV2 → HTML → plain text), so a weird character in a user's content can't break the alert.
+
+---
+
+## Channel 3 — In-app feed + push with [`noticed`](https://github.com/excid3/noticed)
+
+For decisions and outcomes that the *user* should see in your app's notification bell (and on their phone), `noticed` is the multi-channel fan-out. The event envelope drops straight into `Notifier.with(...).deliver(recipients)`:
+
+```ruby
+# config/initializers/moderate.rb
+config.notify = ->(event) do
+  case event.name
+  when :report_decision, :affected_user_decision, :appeal_decision,
+       :user_banned, :content_removed
+    Moderate::DecisionNotifier.with(event: event.to_h).deliver(event.recipients)
+  end
+end
+```
+
+```ruby
+# app/notifiers/moderate/decision_notifier.rb
+class Moderate::DecisionNotifier < Noticed::Event
+  deliver_by :database          # the in-app feed
+  deliver_by :fcm do |config|   # push to devices
+    config.credentials = Rails.application.credentials.fcm
+    config.json { |notification| { title: "Moderation update", body: params.dig(:event, :payload, :summary) } }
+  end
+
+  notification_methods do
+    def message = params.dig(:event, :payload, :summary)
+    def url     = params.dig(:event, :payload, :url)
+  end
+end
+```
+
+Notes:
+
+- Pass **`event.to_h`** (the Hash) rather than the raw event object to `noticed` — `noticed` serializes params to the database, and a plain Hash of GlobalID-able records and scalars stores cleanly. `event.payload[:summary]` doubles as the push body.
+- `event.recipients` is already the correct audience, so `deliver(event.recipients)` needs no massaging.
+- Same `:summary` you used for Telegram works as the push title/body — write the human line once, reuse it across channels.
+
+> This is the [RailsFast Native](https://railsfast.com) path: `noticed` + `:fcm`/APNs gives you the in-app feed and native push from the same decision event, so a moderation outcome reaches the user on web and mobile without a second integration.
+
+---
+
+## Putting all three together (the full hook)
+
+Here's the complete, production-shaped `config.notify` — email via goodmail, admin pings via telegrama, in-app + push via noticed — wired exactly once:
+
+```ruby
+# config/initializers/moderate.rb
+Moderate.configure do |config|
+  config.notify = ->(event) do
+    # --- 1. Email the user (goodmail) ---------------------------------------
+    case event.name
+    when :report_received, :report_decision, :affected_user_decision,
+         :appeal_received, :appeal_decision, :notice_received,
+         :user_banned, :content_removed
+      Array(event.recipients).each do |recipient|
+        next unless recipient.respond_to?(:email) && recipient.email.present?
+        ModerationMailer.with(event: event, recipient: recipient)
+                        .public_send(event.name)
+                        .deliver_later
+      end
+    end
+
+    # --- 2. Ping admins on Telegram (telegrama) -----------------------------
+    case event.name
+    when :report_received, :notice_received, :content_flagged, :appeal_received
+      Telegrama.send_message(event.payload[:summary], formatting: { obfuscate_emails: true })
+    end
+
+    # --- 3. In-app feed + push (noticed) ------------------------------------
+    case event.name
+    when :report_decision, :affected_user_decision, :appeal_decision,
+         :user_banned, :content_removed
+      Moderate::DecisionNotifier.with(event: event.to_h).deliver(event.recipients)
+    end
+  end
+end
+```
+
+Every branch is independent: the same event can email a user **and** ping you on Telegram **and** drop into their in-app feed, or just one of those, depending on which lists you put its name in. One user-facing decision, one moderator click, three channels — no duplicate audience logic, no notification code in your models.
+
+---
+
+## Audit — the other hook
+
+`config.notify` is for telling **people**. `config.audit` is for telling your **records**: an append-only log of every important action, with the *same* envelope, so compliance and forensics don't depend on whether an email went out.
+
+```ruby
+Moderate.configure do |config|
+  config.audit = ->(event) do
+    AuditLog.record!(
+      event_type: event.name,
+      actor:      event.actor,
+      subject:    event.subject,
+      data:       event.payload
+    )
+  end
+end
+```
+
+`audit` fires for **every** event (including the silent ones like `user_blocked` that you usually don't notify on), it's append-only by intent, and it's where DSA **Art. 24 transparency counters** ultimately draw from (notices received, actions taken, appeal outcomes). Wire it once next to `notify` and you have both halves: humans get told, history gets kept.
+
+> [!NOTE]
+> Same envelope (`name` / `subject` / `actor` / `recipients` / `payload` / `to_h`), two destinations. Keep both hooks fast and side-effect-light; push real work (emails, HTTP, heavy writes) to background jobs.

+  #   event.subject      # the record acted on (a Report, Block, Flag, Appeal…)
+  #   event.actor        # who took the action (a moderator, a user, or nil/system)

+  #
+  # Called for every notifiable event. Wire it once and fan out to email
+  # (goodmail), admin alerts (telegrama), in-app + push (noticed) — all from the

+  # ==========================================================================
+  #
+  # `moderate` doesn't own your user lifecycle, so it never bans a user itself.
+  # When a moderator resolves a report with `ban_user: true`, this proc decides

+  #
+  # `moderate` mints signed, single-purpose links (e.g. an appeal link in a
+  # decision email, a confirm-receipt link in a DSA notice). These purposes
+  # scope each signature so a link minted for one action can't be replayed for

Subject: [PATCH 02/15] Build moderate v1 engine: models, concerns, macros,
 filters, services, web, dummy app + tests (172 green)

Extracts the proven Trust & Safety logic into a clean, host-agnostic Moderate:: gem built to the README/docs spec: Report/Block/Flag/Appeal models, Actor/Reportable/ContentFilterable concerns + has_moderation/reportable/moderates macros, the Result/Label canonical taxonomy + wordlist adapter, intake/resolve services (report/appeal/flag) with DSA Art 16/17/20 flows, the mountable notice-form engine + report_link helper + BYOUI controller concern, a test/dummy host app, and a full Minitest suite (172 runs, 0 failures; line 86.6% / branch 65.2%). Inline comments cite DSA/OpenAI/Apple/Google/Rails sources. Zero host (CarHey/ride) references.

Post-build corrections still pending (see TODO): abstract external classifier adapters (no inline OpenAI HTTP/dep; reference impl via ruby_llm), move taxonomy lists from DB check-constraints to model constants+validations, auto-integrate rails_cloudflare_turnstile, and make the engine mount-path host-chosen + prefill/lock the notice form.

+  # one of those guarantees). See docs/madmin.md.

+  # engine (`isolate_namespace Moderate`). Rails does NOT auto-include an isolated
+  # engine's helpers into the host application's views — that's the whole point of
+  # isolation. But `moderate_report_link` is meant to be called from the host's own
+  # templates (e.g. `<%= moderate_report_link(@comment, field: :body) %>`), so we
+  # explicitly mix this module into ActionView for the host at load time via the
+  # `ActiveSupport.on_load(:action_view)` hook at the bottom of this file. That is

+    #   1. there is no signed-in viewer (anonymous users use the public DSA notice

+    #   2. the record doesn't know how to be reported (no `report_visible_to?`), or

+# English blocklist for the built-in :wordlist filter adapter
+# (Moderate::Filters::Wordlist).
+#
+# ── Format ───────────────────────────────────────────────────────────────────
+# Top-level keys are CANONICAL TAXONOMY categories (see Moderate::Label::TAXONOMY,
+# itself the OpenAI omni-moderation-latest taxonomy:
+# https://developers.openai.com/api/docs/guides/moderation). Using the canonical
+# vocabulary here — instead of the ad-hoc bucket names a host might invent — is the
+# whole point: every adapter (this offline wordlist, the OpenAI endpoint, a host's
+# own backend) emits the SAME category set, so Moderate::Flag, the DSA Art. 17
+# statement of reasons, and the Art. 24 transparency counters all aggregate over
+# one set. A category may be a bare top-level slug ("hate") or a slash-qualified
+# subcategory ("hate/threatening") — both are valid canonical slugs.
+#
+# Each category maps to a list of REGEX patterns (Ruby Regexp source strings).
+# Patterns are matched against NORMALIZED text — already lowercased, NFKD-folded
+# (accents stripped), leetspeak-transliterated (0->o, 3->e, @->a, ...), and
+# collapsed to single spaces — AND against the same text with all spaces removed
+# (to defeat "f u c k"-style spacing evasion). So write patterns in lowercase,
+# ASCII, space-separated form; the adapter handles the evasion-resistance.
+#
+# ── Why labels, not the raw word, are stored ─────────────────────────────────
+# The adapter records the matched CATEGORY, never the offending substring, so a
+# validation error or a queue entry never echoes abusive language back into the UI
+# or the logs. (Same discipline as Apple Guideline 1.2 / Google Play UGC reviews
+# expect: https://developer.apple.com/app-store/review/guidelines/#user-generated-content
+# https://support.google.com/googleplay/android-developer/answer/9876937)
+#
+# ── This is a SEED, not a complete classifier ────────────────────────────────
+# A static wordlist is a fast, offline, multilingual FIRST line of defense — it
+# satisfies the store bar of "a method for filtering objectionable UGC before
+# posting" and catches the obvious cases with zero dependencies and zero latency.
+# It is deliberately small and conservative (false positives block real users).
+# For nuanced, context-aware moderation, register the :openai adapter or your own.
+# Extend without editing the gem via `config.additional_words` /
+# `config.excluded_words`.
+
+# Slurs / dehumanizing abuse directed at protected groups -> hate.
+# Write plain word-boundary patterns; the adapter's normalization (NFKD fold,
+# leetspeak, punctuation collapse) plus the compact-form match handle spacing and
+# symbol evasion, so there's no need to hand-encode "n i g g e r" variants here.

+    # value — the default no-op hook returns nil ⇒ false, which correctly signals
+    # "nothing was sent."

+    # The adapter contract is the whole point of the gem's filtering design: ANY
+    # object responding to `classify(value) → Moderate::Result` is a valid adapter,
+    # so the built-in wordlist/image backends and a host's registered remote

+  # The single configuration object the host populates in

+  #
+  # Design rules, straight from docs/configuration.md:
+  #   - Config is read AT THE POINT OF USE, not frozen at boot. Class names are
+  #     stored as strings and constantized lazily, so the initializer works no
+  #     matter when the app loads (the User model may not exist yet at boot).
+  #   - Validating setters normalize their input (`to_s.strip.downcase.to_sym`) so
+  #     "Block", :block and " block " all mean the same thing, and raise a
+  #     plain-English ArgumentError on a bad value — failing fast at the assignment
+  #     line. `validate!` runs once more at the end of `configure` for cross-field
+  #     checks (e.g. a :block filter pointed at an async adapter).
+  #   - Every hook (`audit`/`notify`/`on_block`/`ban_handler`) defaults to a no-op,
+  #     so the gem works untouched and a host wires hooks only as needed.
+  #
+  # This mirrors the validating-setter convention across the ecosystem
+  # (usage_credits' `default_currency=`, wallets' `default_asset=`).

+

+    # checks already caught most typos; this catches the things that need the whole
+    # block resolved:
+    #   - the default text adapter must actually be registered
+    #   - every per-field filter must name a registered adapter
+    #   - a :block-mode filter must use a SYNCHRONOUS adapter — you can't reject a

+module Moderate
+  # The Rails engine that wires `moderate` into a host app.
+  #
+  # It's an ISOLATED engine (`isolate_namespace Moderate`) for the same reason
+  # Devise's is: the gem ships a mountable public DSA notice form
+  # (`mount Moderate::Engine => "/legal"`, see docs/dsa-notice-form.md) with its
+  # own controllers, views, helpers, and `moderate_`-prefixed tables. Isolation
+  # keeps every one of those from colliding with the host app's namespace, and
+  # gives the host the `moderate.` URL-helper proxy for the mounted routes.
+  #
+  # NOTE: the engine is intentionally thin. The host can use the whole gem
+  # (reporting, blocking, filtering, the queue) WITHOUT mounting anything — the
+  # mount is only needed for the public Art. 16 notice form. Everything here is
+  # plumbing that runs whether or not the engine is mounted.
+  class Engine < ::Rails::Engine
+    isolate_namespace Moderate
+
+    # The autoloadable code that needs the host's ActiveRecord/ApplicationRecord and
+    # the host's `config.user_class` to exist before it loads — the four AR models,
+    # the three model concerns, the async classify job, the filter adapters, and the
+    # service objects — lives under `lib/moderate/{models,jobs,filters,services}`,
+    # NOT under the engine's `app/` tree. That's a deliberate gem-packaging choice
+    # (everything ships under `lib/`), but it means we have to teach the host's
+    # Zeitwerk loader about that subtree ourselves, with three corrections:
+    #
+    #   1. NAMESPACE. A bare `eager_load_paths << ".../lib/moderate"` would map the
+    #      directory to the TOP-LEVEL namespace, so Zeitwerk would expect
+    #      `lib/moderate/configuration.rb` to define `::Configuration` (not
+    #      `Moderate::Configuration`) and blow up with "uninitialized constant
+    #      Configuration" during eager load. We push the dir mapped to the `Moderate`
+    #      module instead, so `lib/moderate/models/report.rb` → `Moderate::Report`.
+    #      (Zeitwerk's `push_dir(path, namespace:)` is exactly for this — see
+    #      https://github.com/fxn/zeitwerk#custom-root-namespaces.)
+    #
+    #   2. COLLAPSED DIRECTORIES. `models/`, `models/concerns/`, and `jobs/` are
+    #      organizational, not namespace, segments — `report.rb` must be
+    #      `Moderate::Report`, NOT `Moderate::Models::Report`; `actor.rb` must be
+    #      `Moderate::Actor`, not `Moderate::Models::Concerns::Actor`. We `collapse`
+    #      them so they contribute no namespace. (`services/` and `filters/` are
+    #      KEPT, because the code intentionally namespaces `Moderate::Services::*`
+    #      and `Moderate::Filters::*`.)
+    #
+    #   3. IGNORED FILES. The gem's SPINE (`version`, `errors`, `label`, `result`,
+    #      `event`, `configuration`, `engine`, `macros`) is `require_relative`'d from
+    #      `lib/moderate.rb` so the value objects work in a plain-Ruby context with
+    #      no Rails — those files MUST NOT also be managed by Zeitwerk (a constant
+    #      can't be both manually required and autoloaded). The 0.x compatibility
+    #      shims (`text`, `text_validator`, `word_list`) are ignored too: they either
+    #      define non-conventional constants (`text_validator.rb` reopens
+    #      `ActiveModel::Validations`, not a `Moderate::*` constant) or are legacy and
+    #      loaded only on demand.
+    #
+    # We do this on the host's MAIN autoloader (`Rails.autoloaders.main`) inside an
+    # initializer scheduled BEFORE `:set_autoload_paths`, the same point Rails wires
+    # up its own roots — so our `push_dir`/`collapse`/`ignore` are in place before
+    # Zeitwerk's `setup`/`eager_load` ever run.

+module Moderate
+  # The built-in filter adapters live under `Moderate::Filters`. They're the
+  # gem's own implementations of the ONE adapter contract the whole filtering
+  # design hinges on:
+  #
+  #     adapter.classify(value) -> Moderate::Result
+  #
+  # ...where `value` is a piece of user content (a String of text, or an image
+  # reference) and the returned `Moderate::Result` answers "is this allowed?" and,
+  # if not, "why?" (the per-`Moderate::Label` detail, mapped onto the gem's single
+  # canonical taxonomy — see `Moderate::Label`).
+  #
+  # ── How adapters are invoked ────────────────────────────────────────────────
+  # The configuration registry (`Moderate::Configuration#adapters`) stores each
+  # adapter as EITHER a live object the host registered, OR a class-NAME String the
+  # gem constantizes lazily. The two built-ins are seeded as the strings
+  # "Moderate::Adapters::Wordlist" / "Moderate::Adapters::Image", and
+  # `Configuration#resolve_adapter` returns the CLASS itself for a String/Class
+  # entry. That means the gem calls `SomeAdapterClass.classify(value)` and
+  # `SomeAdapterClass.synchronous?` — i.e. the built-ins expose CLASS methods, not
+  # instance methods. (A host's own adapter registered as an instance exposes the
+  # same `#classify`/`#synchronous?` on that instance — same duck type, both work.)
+  #
+  # `Base` gives the built-ins both halves of that duck type from a single source:
+  # subclasses implement the work as an INSTANCE method (`#classify`), and `Base`
+  # provides the CLASS-level `classify`/`synchronous?`/`async?` that the registry
+  # resolution path calls, delegating the class call to a fresh instance. So one
+  # implementation satisfies both call styles and there's no copy-paste.
+  #
+  # ── Sync vs. async (why it matters for :block) ──────────────────────────────
+  # `Configuration#validate!` enforces the README's rule: a `:block`-mode filter
+  # MUST use a synchronous adapter, because you can't reject a save on a result
+  # that's still computing in a background job. The validator probes the adapter
+  # with `synchronous?` and treats anything that doesn't answer, or answers truthy,
+  # as synchronous (the safe default that keeps simple adapters working); only an
+  # adapter that explicitly returns `synchronous? == false` is rejected for :block.
+  #
+  # We model this once here as `async?` (default `false` — built-ins are sync) and
+  # derive `synchronous?` from it, so a subclass flips ONE flag
+  # (`def self.async? = true`) to declare itself background-only. The OpenAI adapter
+  # does exactly that; the wordlist and image adapters leave the default.

+    # ── Why a "route everything to human review" default ──────────────────────────
+    # Apple Guideline 1.2 and Google Play's UGC policy require a method for filtering
+    # objectionable media before it's posted, not just text
+    # (https://developer.apple.com/app-store/review/guidelines/#user-generated-content,
+    # https://support.google.com/googleplay/android-developer/answer/9876937). But the
+    # gem can't ship a real NSFW/CSAM image CLASSIFIER offline — that needs a model or
+    # a hosted service. So the safe, honest default is: don't PRETEND to evaluate the
+    # pixels; instead FLAG every uploaded image so a human sees it in the moderation
+    # queue (Moderate::Flag.pending). That clears the store bar (there IS a review
+    # path) without making a false claim that the bundled gem inspects image content.
+    #
+    # A host that wants automated image moderation swaps this out in one line — point
+    # the field at the multimodal :openai adapter (which DOES inspect pixels), or
+    # register their own SafeSearch / Rekognition / Hive backend:

+    # Naive substring matching is trivially defeated ("f.u.c.k", "FÜCK", "f u c k",
+    # "fuuuck", "fμck"). Before matching, text is NORMALIZED:
+    #   1. Unicode NFKD decomposition + stripping combining marks — folds accented
+    #      and look-alike forms ("FÜCK" -> "fuck") to a plain base form. NFKD
+    #      (compatibility decomposition) also flattens many homoglyph/fullwidth
+    #      tricks. (Ruby String#unicode_normalize; \p{Mn} = Unicode "Mark,
+    #      nonspacing", the combining accents.)
+    #   2. Leetspeak transliteration (0->o, 1->i, 3->e, 4->a, 5->s, 7->t, @->a,
+    #      $->s) — folds the common letter/number/symbol swaps.
+    #   3. Lowercasing + collapsing every run of non-alphanumerics to a single space
+    #      — kills punctuation-as-separator evasion ("f.u.c.k" -> "f u c k").
+    # The normalized text is then matched in TWO forms: the single-spaced form
+    # (so word-boundary patterns like "\bkill yourself\b" work), AND a space-removed
+    # "compact" form (so spacing evasion "f u c k" -> "fuck" is caught). A pattern
+    # hits if it matches EITHER form. This is the proven, evasion-resistant
+    # matching strategy the adapter relies on.
+    #
+    # ── Output ───────────────────────────────────────────────────────────────────

+module Moderate
+  # The background worker for ASYNCHRONOUS filter adapters (the :openai adapter, a
+  # host's hosted classifier, the default :image adapter) running in :flag mode.
+  #
+  # ── Why a job exists at all ──────────────────────────────────────────────────
+  # An async adapter does blocking I/O (a moderation API call), which must never run
+  # inside the request that saved the content — and CANNOT run inside a validator or
+  # an after_commit callback without stalling the write. So the :flag path works in
+  # two halves:
+  #   1. The model's filter concern (`moderates :field`) lets the write succeed, then
+  #      in an after_commit hook enqueues THIS job for any field whose policy uses an
+  #      async adapter. (Synchronous adapters like :wordlist skip the job — the
+  #      concern classifies inline and files the Flag directly.)
+  #   2. This job re-reads the saved value, classifies it through the adapter, and —
+  #      if the content is flagged — files (or updates) a Moderate::Flag for the
+  #      moderation queue.
+  #
+  # ── Re-reading the value (deliberate) ────────────────────────────────────────
+  # The job is handed the RECORD (GlobalID-serialized by ActiveJob) and the FIELD
+  # NAME, not the raw text/image — so it always classifies the CURRENT persisted
+  # value. If the record was edited or deleted between enqueue and run, we classify
+  # what's actually there now (or skip a vanished record), never a stale snapshot.
+  #
+  # ── Idempotency ──────────────────────────────────────────────────────────────
+  # Flag creation goes through `Moderate::Flag.flag!`, the single builder shared by
+  # the synchronous and asynchronous paths. It's an upsert-by-(flaggable, field,
+  # source) so a retried job (ActiveJob retries on transient failures) doesn't pile
+  # up duplicate queue entries for the same content.
+  #
+  # ── Base class ───────────────────────────────────────────────────────────────
+  # We subclass `ActiveJob::Base` directly (not the host's ApplicationJob) so the gem
+  # doesn't depend on a constant that lives in the host app — the same reason the
+  # rest of the gem stays host-agnostic. The host configures the queue adapter,
+  # retries, and queue name globally as usual.
+  class ClassifyJob < ActiveJob::Base

+# constants and make Zeitwerk raise on its eager-load pass ("already defined").
+#
+# This is safe because the macro methods below only REFERENCE the concern constants
+# inside their bodies (`include Moderate::Actor`), which run when a host model calls

+  # The engine does `ActiveSupport.on_load(:active_record) { extend Moderate::Macros }`,
+  # so `has_moderation`, `reportable`, and `moderates` become class methods on
+  # ActiveRecord::Base — readable plain-English declarations that sit alongside the
+  # rest of a host's stack (`has_credits`, `has_wallets`, `has_api_keys`):

+  # Each macro is exact sugar for an `include` + a declaration — the README
+  # documents both forms as equivalent. The macros are deliberately thin: they

+  #            synchronously, so it only works with a synchronous adapter — the

+    # This is the regulator-facing intake: the "Report illegal content (EU)" form
+    # you see at the bottom of X / YouTube / Reddit, open to ANYONE (not just
+    # logged-in users), by electronic means, with a confirmation of receipt. It is
+    # legally distinct from the in-app "Report" button:
+    #   - it carries a `legal_reason` from the DSA statement-of-reasons taxonomy
+    #     (the law's vocabulary) rather than a community `category` (your rules);
+    #   - the notifier may be anonymous (a name+email, not a User);
+    #   - it requires the exact electronic location (URL) of the content — Art.16(2)(b);
+    #   - it requires a good-faith attestation — Art.16(2)(d).
+    # See: https://eur-lex.europa.eu/eli/reg/2022/2065/oj (Article 16).
+    #
+    # A notice is NOT a fourth table: it's a `Moderate::Report` with

+    # window, statement-of-reasons path, and Art. 24 transparency counters as an
+    # in-app report. One queue, one decision workflow, two front doors. This service
+    # builds that notice-kind Report and hands it to IntakeReport for the shared

+    # event whose delivery boolean gates the Art. 16(4) "confirmation of receipt".

+    #     side effects live in exactly one place — easy to test, impossible to
+    #     accidentally skip from a second call site.
+    #   - The same shape is reused by the public DSA notice path (see IntakeNotice),
+    #     which delegates here once it has assembled a notice-kind Report. One intake,
+    #     two front doors.

+    # ResolveFlag — the decision on an auto-filter `Moderate::Flag`, behind the
+    # flag's `action!` / `dismiss!`.
+    #
+    # A Flag is a SYSTEM-raised queue item (the wordlist/image/external classifier
+    # tripped on a `:flag`-mode field, or a human filed one manually) — it's the
+    # "ongoing moderation" surface Apple Guideline 1.2 and Google Play UGC expect:
+    #   - https://developer.apple.com/app-store/review/guidelines/#user-generated-content
+    #   - https://support.google.com/googleplay/android-developer/answer/9876937
+    #
+    # A flag is lighter than a report: there's no reporter to inform and no appeal
+    # window to stamp (an appeal attaches to a *report* decision, not to a raw
+    # queue item). So this service is the simplest of the resolvers — atomic
+    # transition, mandatory note, audit — but it follows the same discipline:
+    #   - `with_lock` + re-check `pending?` inside the lock for idempotency under
+    #     concurrent review;
+    #   - a NOTE IS MANDATORY (the moderator's rationale is the audit trail);
+    #   - the decision is recorded via `Moderate.audit`, never a host-specific log.
+    #
+    # NOTE: unlike ResolveReport, resolving a flag does NOT itself run content
+    # removal/bans. A flag marks "this needs a look"; the enforcement decision is a
+    # *report* concern. If a moderator wants to remove the flagged content, they file
+    # /resolve a report on it. This keeps the flag a pure triage record and avoids
+    # two divergent enforcement paths. (Documented so a maintainer doesn't "helpfully"
+    # add removal here and create that divergence.)

+
+module Moderate
+  module Services
+    # ResolveReport — the audited decision engine behind `report.resolve!` /
+    # `report.dismiss!`.
+    #
+    # This is where a moderator's decision actually happens, and it's the most
+    # legally-loaded path in the gem, so it's built defensively:
+    #
+    #   1. ATOMIC + IDEMPOTENT. The whole transition runs inside `report.with_lock`
+    #      (a SELECT ... FOR UPDATE row lock). Two moderators clicking "resolve" at
+    #      once must not both run enforcement (double-ban, double-remove) — the lock
+    #      serializes them, and we RE-CHECK `open?` *inside* the lock after reload so
+    #      the second one sees the closed record and bails with a clean error rather
+    #      than re-applying actions.
+    #
+    #   2. A NOTE IS MANDATORY. DSA Art. 17 requires a "clear and specific statement
+    #      of reasons"; the moderator's note is the human-readable ground. No note,
+    #      no decision — we raise RecordInvalid with the note error attached.
+    #      See: https://eur-lex.europa.eu/eli/reg/2022/2065/oj (Article 17).
+    #
+    #   3. ENFORCEMENT IS HOST-AGNOSTIC. Content removal calls the reportable's own
+    #      `remove_reported_field!` (the host decides what "remove" means for its
+    #      content); a ban calls `Moderate.apply_ban` → the host's `ban_handler`
+    #      (the host decides what "banned" means). The gem never reaches into a
+    #      host's domain — it only invokes the contracts.
+    #
+    #   4. TWO DECISION EVENTS, ON PURPOSE. `report_decision` tells the *reporter*
+    #      "we handled it" (Art. 16(5)); `affected_user_decision` gives the *content
+    #      owner* the Art. 17 statement of reasons (action taken, ground, automated-
+    #      means disclosure, appeal path). Different people, different rights — see
+    #      docs/notifications.md ("Why two decision events").

Subject: [PATCH 03/15] Apply post-build corrections: abstract external
 adapters, model-side taxonomy, turnstile auto-integration, host-chosen mount
 + form prefill/lock
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

#1 External classifiers are no longer shipped/loaded or implied deps: deleted the inline OpenAI (Net::HTTP) + image adapters; :wordlist is the only built-in; OpenAI (via ruby_llm) and AWS Rekognition are copy-and-register REFERENCE adapters in examples/. Dropped the Moderate::Adapters alias namespace.

#2 Taxonomy moved from DB check-constraints to frozen model constants + ActiveModel inclusion validations (category host-overridable via config.report_categories); migrations keep only structural constraints (NOT NULL, unique block index, self-block, FKs, message length).

#3 The public DSA notice form auto-detects rails_cloudflare_turnstile (widget + server verify) when present, with a config.notice_guard no-op fallback — no ENV/config needed.

#4 Engine routes are relative; the HOST chooses the mount point (no hardcoded /legal). The notice form prefills from X-style query params (content_url/author/id) + Devise current_user, locks the auto-prefilled identity fields, and keeps reported-content fields editable.

Suite green: 176 runs, 692 assertions, 0 failures (line 89% / branch 69%). Zero host (CarHey/ride) references.

A notice is a `Moderate::Report` with `intake_kind: "dsa"` (no separate model), built via `Moderate::Services::IntakeNotice`. The form prefills the reported-content fields from query params (editable) and a signed-in notifier's identity (locked), and auto-integrates [`rails_cloudflare_turnstile`](https://github.com/instrumentl/rails-cloudflare-turnstile) when present (falling back to a `config.notice_guard` proc). See [`docs/dsa-notice-form.md`](docs/dsa-notice-form.md).
 - **DSA Art. 17 (statement of reasons):** decision notices state the action, the legal/contractual ground, whether automated means were used, and the redress path.
 - **DSA Art. 20 (appeals):** a free, electronic internal complaint mechanism, open ≥ 6 months, decided by a human.
 - **DSA Art. 24 (transparency):** counters you can publish (notices received, actions taken, median handling time, appeal outcomes).

+> Two taxonomies, on purpose: an in-app **community report** category set (harassment, spam, …) and a separate, regulator-aligned **DSA legal-reason** taxonomy for public notices. `moderate` ships both. The community set is host-customizable via `config.report_categories`; the DSA legal-reason taxonomy is regulator-defined and fixed.
 
 ## 🤓 Why the models?
 
 `rails generate moderate:install` creates four tables:
 
-- **`moderate_reports`** — a report/notice + an immutable evidence snapshot + decision metadata + the appeal window. Serves both in-app reports and public DSA notices (distinguished by `kind`).
+- **`moderate_reports`** — a report/notice + an immutable evidence snapshot + decision metadata + the appeal window. Serves both in-app reports and public DSA notices (distinguished by `intake_kind`).
 - **`moderate_blocks`** — the bidirectional `blocker`/`blocked` edge, with a self-block check and the SSOT relation behind `Moderate.blocked_ids_for`.
 - **`moderate_flags`** — system/auto-filter flags (source: `text_filter` / `image_filter` / `external_classifier` / `manual`), with the classifier's labels + scores; the queue both human admins and ML consumers read via `pending`.
 - **`moderate_appeals`** — DSA Art. 20 internal complaints against a decision.
 
+> The value-list taxonomies (community `category`, `status`, `content_type`, the DSA `legal_reason`/`legal_country_code`, `resolution_basis`, plus `Flag` source/mode/status and `Appeal` source/status) are validated **in the models** — frozen constants + ActiveModel `inclusion` validations — **not** by database `CHECK` constraints. That means **adding or customizing a label never requires a migration**: the community category list is host-overridable via `config.report_categories` (defaults to `Moderate::Report::DEFAULT_CATEGORIES`), and the gem can grow its own taxonomies in a point release without touching your schema. The only value guard kept at the DB level is a cheap message-length backstop; everything else the migration adds is structural (NOT NULLs, FKs, the unique block edge, and the self-block CHECK).
+
 The migration is **adaptive**: it matches your app's primary-key type (UUID or bigint) and JSON column type (`jsonb` / `json`) automatically, so it drops cleanly into any Rails 7.1+ schema.

 The EU **Digital Services Act, Article 16 ("Notice and action")** says every hosting service that serves EU users must offer a **public, electronic** way for *anyone* — not just logged-in users — to flag illegal content, and must **acknowledge receipt** of that notice. This is the form you see at the bottom of X, YouTube, Reddit: "Report illegal content (EU)".

+| --- | --- | --- | --- |
+| `content_url` | the exact URL field | `subject_url` | Art. 16(2)(b) — "the exact electronic location" |
+| `content_type` | the content-type select | `content_type` | the host-agnostic bucket for the snapshot/queue |
+| `content_author` | the account/handle field | `reported_account_identifier` | optional host-side identity of the content |

+        content_author: @author.username
+      ) %>
+```
+
+These are the **reported-content** fields, so they stay fully **editable** — the notifier may correct the URL, change the content type, etc. `content_type` is only echoed when the query value is one the model would actually accept (a crafted `?content_type=<script>` is ignored), so a query param can't pre-poison the select.
+
+### Identity prefill + lock (from Devise `current_user`, locked)
+
+The form is public and anonymous-friendly, but when someone **is** logged in we prefill their **name/email** from `current_user` (detected safely — the gem never hard-depends on Devise; it checks `respond_to?(:current_user)`). Those **identity** fields are then rendered **readonly (locked)** so a logged-in notifier can't put someone else's name/email on a legal notice — and the controller **re-asserts identity server-side** on submit, so even a tampered request that re-enables the field can't spoof it. For an anonymous notifier (no `current_user`) the name/email fields are blank and editable — they're the only identity there is.

+#### The bot gate (auto-integrates `rails_cloudflare_turnstile`)
+
+A public, unauthenticated form is a spam magnet. `moderate` ships a **single, request-time bot gate** (`verify_human!`) that auto-adapts to your bundle — with **zero wiring**:
 
-#### The Turnstile-gate hook
+- **If the [`rails_cloudflare_turnstile`](https://github.com/instrumentl/rails-cloudflare-turnstile) gem is installed**, the gate uses it automatically. That gem mixes its helpers in for you, so:
+  - the **view renders the widget** (`cloudflare_turnstile` + `cloudflare_turnstile_script_tag`), and
+  - the **controller verifies the challenge server-side** (`validate_cloudflare_turnstile`); a failed challenge (the gem's `RailsCloudflareTurnstile::Forbidden`) is turned into a friendly `422` so the submitter can retry.
 
-A public, unauthenticated form is a spam magnet. `moderate` ships a **Cloudflare Turnstile** gate as a `before_action` that:
+  You add the gem and its keys (its own `config/initializers/cloudflare_turnstile.rb`) — `moderate` needs **no env var and no config** to pick it up. Detection is via `defined?`/`respond_to?`, and `rails_cloudflare_turnstile` is **not** a dependency of `moderate`.
+- **Otherwise**, the gate falls back to a configurable proc, `config.notice_guard` (no-op by default, so the form just works in dev/test and for apps that gate at the edge). The proc receives the controller and returns a boolean:
 
-- **No-ops when unconfigured.** If `notice_turnstile_site_key`/`secret_key` are blank, the gate is skipped entirely and the form just works (great for dev/test and for apps that gate at the edge instead).
-- **Renders the widget** in the default view when the site key is present (the view checks `Moderate.configuration.notice_turnstile_site_key.present?`).
-- **Verifies server-side** on `create` by POSTing the response token to Turnstile's `siteverify`; a failed/missing token re-renders `new` with `422` and a friendly error.
-- **Is pluggable.** Prefer hCaptcha, reCAPTCHA, or your own check? Set `config.notice_captcha_verifier = ->(controller) { ... boolean ... }` and the built-in Turnstile path steps aside.
+  ```ruby
+  # Use hCaptcha / reCAPTCHA / your own check instead of Turnstile:
+  config.notice_guard = ->(controller) { MyCaptcha.verify(controller.params["my-token"]) }
+  ```
 
-We default to Turnstile (not reCAPTCHA) because it's privacy-friendly, free, and the RailsFast house default — but the verifier is just a lambda, so you're never locked in.
+  An exception in the guard is treated as "failed closed" (re-render the form so the submitter retries) — a flaky bot service must never 500 a legal notice form.
+
+We default to recommending Turnstile (privacy-friendly, free, the RailsFast house default), but you're never locked in: the guard is just a lambda.
 
 #### The rate-limit hook
 
-On Rails 7.2+ the controller uses the built-in `rate_limit` API; on 7.1 it falls back to a tiny cache-backed counter (`Rails.cache`, per-IP). Configure it once:
+On Rails 7.2+ you could use the built-in `rate_limit` API; `moderate` instead implements a tiny per-IP, cache-backed counter (`Rails.cache`) as a `before_action`, so it honors your **runtime** `config.notice_rate_limit` (the class-level macro is evaluated at class load, before your initializer has run). Configure it once:
 
 ```ruby
 config.notice_rate_limit = { max: 5, within: 1.hour }   # default
 config.notice_rate_limit = false                        # disable (you throttle at the edge)
 ```
 
-When tripped, `create` responds `429 Too Many Requests` with a retry-after message, rendered through the same (overridable) view. Both gates are deliberately **defense in depth** and both degrade to "off" gracefully, so the form never becomes a support burden in environments where you don't need them.

+# REFERENCE ADAPTER — NOT shipped, NOT loaded, NOT a dependency of `moderate`.
+#
+# `moderate` ships exactly ONE built-in adapter: the offline `:wordlist` (text).
+# It does NOT bundle an image classifier — a real NSFW/CSAM model needs a hosted
+# service or a model you can't ship offline. This file is a "bring your own" IMAGE
+# adapter: copy it into your app, add the AWS SDK gem to YOUR Gemfile, and register
+# it. The gem has no `aws-sdk-rekognition` dependency, so nothing here is pulled
+# into a host that doesn't want it.
+#
+# ── How to use it ─────────────────────────────────────────────────────────────
+#   1. Copy this file into your app (e.g. app/adapters/aws_rekognition_adapter.rb).
+#   2. Add the runtime dependency to YOUR app's Gemfile:
+#          gem "aws-sdk-rekognition"
+#      and provide AWS credentials the usual way (ENV / IAM role / shared config).
+#   3. Register the adapter and point an image field at it, in :flag mode:
+#          Moderate.configure do |config|
+#            config.register_adapter(:rekognition, AwsRekognitionAdapter.new)
+#            config.filter "Profile", :avatar, with: :rekognition, mode: :flag
+#          end
+#      Hand the adapter the image BYTES (the value your model's filtering seam
+#      passes for the field — e.g. an attachment's `download`), or pass an
+#      { s3_object: { bucket:, name: } } hash to moderate an object already in S3.
+#
+# ── Why :flag, never :block ───────────────────────────────────────────────────
+# `synchronous? == false` (below): a Rekognition call is blocking network I/O, so
+# `moderate` runs it in `Moderate::ClassifyJob` (:flag mode) and refuses it in
+# :block mode — you can't synchronously reject a save on an in-flight API call.
+#
+# ── Taxonomy mapping ──────────────────────────────────────────────────────────
+# Rekognition has its OWN moderation taxonomy (top-level + second-level labels like
+# "Explicit Nudity" / "Violence" / "Drugs"), NOT OpenAI's. Every adapter must map
+# its provider labels onto the gem's ONE canonical taxonomy (Moderate::Label), so
+# Moderate::Flag, the DSA statement of reasons, and the transparency counters all
+# speak one vocabulary. CATEGORY_MAP below is that mapping — adjust it to taste.

+# ──────────────────────────────────────────────────────────────────────────────
+# REFERENCE ADAPTER — NOT shipped, NOT loaded, NOT a dependency of `moderate`.
+#
+# `moderate` ships exactly ONE built-in adapter: the offline `:wordlist`. Every
+# other backend — including this OpenAI one — is "bring your own": you copy this
+# file into your app, add its gem to YOUR Gemfile, and register it yourself. The
+# gem deliberately has no `ruby_llm`/`openai`/HTTP dependency, so nothing here is
+# pulled into a host that doesn't want it.
+#
+# ── How to use it ─────────────────────────────────────────────────────────────
+#   1. Copy this file into your app (e.g. app/adapters/openai_moderation_adapter.rb).
+#   2. Add the runtime dependency to YOUR app's Gemfile:
+#          gem "ruby_llm"
+#      and configure your key (https://github.com/crmne/ruby_llm):
+#          RubyLLM.configure { |c| c.openai_api_key = ENV["OPENAI_API_KEY"] }
+#   3. Register the adapter and point a field at it, in :flag mode:
+#          Moderate.configure do |config|
+#            config.register_adapter(:openai, OpenAIModerationAdapter.new)
+#            config.filter "Message", :body, with: :openai, mode: :flag
+#          end
+#
+# ── Why :flag, never :block ───────────────────────────────────────────────────
+# This adapter declares `synchronous? == false` (see below), so `moderate` routes
+# it through `Moderate::ClassifyJob` in :flag mode and REFUSES it in :block mode.
+# You can't synchronously reject a save on a result that's still in flight over the
+# network — that's the spine's documented rule ("`:block` requires a synchronous
+# adapter"). An async classifier allows the write, classifies in a job, and files a
+# `Moderate::Flag` for review.
+#
+# ── Why `omni-moderation-latest` ──────────────────────────────────────────────
+# OpenAI's moderation endpoint is free and the omni model is multimodal (text AND
+# image in one call). Crucially, its category set IS the gem's canonical taxonomy
+# (`Moderate::Label`) — so the mapping below is 1:1, no lossy translation.
+# OpenAI moderation guide:  https://developers.openai.com/api/docs/guides/moderation
+# ruby_llm moderation API:  https://github.com/crmne/ruby_llm
+# ──────────────────────────────────────────────────────────────────────────────

+  MODEL = "omni-moderation-latest"

+  # The single adapter contract: classify(value) -> Moderate::Result.

+  # `value` is whatever the gem hands an adapter for the field — typically a String

-# the gem's canonical Moderate::Label taxonomy:
-# https://developers.openai.com/api/docs/guides/moderation
-#
-# NO NETWORK. Every test STUBS Net::HTTP (via Mocha, already loaded by test_helper)
-# so the request never leaves the process — we assert on (a) what the adapter sends
-# and (b) how it parses a canned response. The adapter is documented to "fail OPEN"
-# on any error (a moderation API is defense-in-depth, not a gatekeeper that should
-# take down posting on an upstream blip), so we also assert the fail-open paths.
-#
-# The adapter reads its key from config.openai_api_key (not defined on the stock
-# Configuration) OR ENV["OPENAI_API_KEY"]; we set the ENV var so the request path is
-# exercised, and restore it in teardown so other tests see a clean environment.
-# NOTE: top-level test class (not nested under `Moderate::Filters`) — same reasoning
-# as WordlistFilterTest: opening the explicit `Moderate::Filters` class to hang a
-# *_test on it would force its Zeitwerk autoload at class-definition time. The
-# `Moderate::Filters::OpenAI` references inside the methods autoload lazily at call time.

+#   - POST /trust/notices with a well-formed notice CREATES a Moderate::Report with

+Some clients cannot render a browser challenge at all (for example a native shell

+verified the request). For those cases, keep the browser gate on for normal traffic
+and skip it per request:
+
+```ruby

+off the public form's bot gate.

 > [!TIP]
 > **🚀 Ship your next Rails app 10x faster!** I've built **[RailsFast](https://railsfast.com/?ref=moderate)**, a production-ready Rails boilerplate template that comes with everything you need to launch a software business in days, not weeks. Go [check it out](https://railsfast.com/?ref=moderate)!

It ships **DSA-compliant** (EU Digital Services Act) and aligned with the **Apple App Store** and **Google Play** review guidelines for user-generated content, so you stop leaving store approvals and legal exposure to chance.

+Because `moderate` is UI-agnostic, it does not render a built-in "under review" badge. Use `flagged?` / `flagged?(:field)` to render copy that fits your product when `:flag` mode lets content through but queues it for review.
+
+If your app runs inside Hotwire Native / Turbo Native, remember that native path configuration is host-owned. Add rules for the in-app report routes you mount (for example `/reports/new` **and** the form action `/reports`, so validation errors stay in the same modal stack) and for the engine's public legal routes **and their form actions** such as `/legal/report/notices/new`, `/legal/report/notices`, `/legal/report/appeals/new`, and `/legal/report/appeals`. `moderate` can provide the Rails routes; your native shell still decides whether they push, present modally, use a sheet, and which Android `uri` maps to the destination.

 Adding a new reportable type is one `reportable` line — the intake, queue, snapshot, and admin code never change.

Validators must be side-effect-free, and a flag created inside a rolled-back transaction would silently vanish — so `moderate` creates the flag **after commit**, correctly, for you.

+# Changelog
+
+All notable changes to this project are documented here.
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [1.0.0] - unreleased
+
+A complete, ground-up rewrite. `moderate` graduates from a single-purpose profanity
+validator (0.1.0) into a full **Trust & Safety** engine for Rails apps with user-generated
+content: report, block, filter, a moderation queue, appeals, and EU DSA / App Store / Google
+Play **aligned** primitives. (First cut ships as `1.0.0.beta1`.)
+
+> **Breaking:** 1.0 keeps the gem name but is an entirely new API. The 0.x profanity
+> validator (`validates :field, moderate: true`) still loads for backward compatibility
+> (see _Upgrading from 0.x_), but everything else is new. Pin `~> 0.1` if you relied on the
+> old behavior and are not ready to adopt the new surface.
+
+### Added
+
+- **Reporting.** `Moderate::Report` plus the `reportable :fields` macro and
+  `Actor#report!(reportable, category:, details:)`. Reports and DSA notices share one model
+  and one queue (`intake_kind: "community" | "dsa"`).
+- **Blocking.** `Moderate::Block`, the `has_moderation_capabilities` actor macro, and
+  `block!` / `unblock!` / `blocks?` / `blocked_by?` / `blocked_with?`. `Moderate.blocked_ids_for(user)`
+  is the bidirectional single source of truth you compose into feed/search/inbox queries.
+  Optional `config.on_block` teardown hook runs inside the block transaction.
+- **Content filtering.** The `moderates :field, mode: :off|:block|:flag, with: :adapter` macro
+  (and the equivalent `config.filter`), the offline multilingual `:wordlist` adapter (the only
+  built-in), the `classify(value) => Moderate::Result` adapter contract with
+  `config.register_adapter`, asynchronous classification via `Moderate::ClassifyJob`, and
+  ready-to-copy reference adapters for OpenAI omni-moderation and AWS Rekognition under
+  `examples/` (bring-your-own, never a dependency).
+- **Moderation queue & decisions.** `Moderate::Flag` and the service objects
+  `Moderate::Services::{IntakeReport, ResolveReport, ResolveFlag, IntakeAppeal, ResolveAppeal,
+  IntakeNotice}`. Decisions are taken under a row lock, re-check open state, apply enforcement
+  (remove content / ban) inside the transaction, and fire notifications outside it; the appeal
+  window and statement-of-reasons fields are stamped automatically.
+- **DSA-aligned primitives.** A mountable public **notice-and-action** form (Art. 16) you mount
+  at any path, **statement of reasons** (Art. 17), internal **appeals** (Art. 20), and
+  **transparency** counters (Art. 24). The notice form prefills from query params + the signed-in
+  user, locks auto-filled identity fields, and auto-detects `rails_cloudflare_turnstile`.
+- **Hooks (all no-op by default).** `config.audit`, `config.notify` (returns a delivery boolean
+  used to gate `decision_notified_at`), `config.on_block`, `config.ban_handler`, the
+  host-overridable `config.report_categories`, and `config.notice_human_verification_skip_if` /
+  `config.appeal_human_verification_skip_if` for native-app bot-gate carve-outs.
+- **Optional integrations**, all auto-detected at runtime via `defined?`/`respond_to?` and never
+  hard dependencies: madmin, goodmail, telegrama, noticed, rails_cloudflare_turnstile.
+- **Install tooling.** `rails generate moderate:install` writes a documented initializer and an
+  adaptive migration (uuid/bigint primary keys, jsonb/json/MySQL JSON columns); `moderate:views`
+  ejects the notice form for customization.
+
+### Changed
+
+- Taxonomies (report categories, DSA legal reasons, country codes) are now frozen model
+  constants with inclusion validations instead of DB `CHECK` constraints — adding or
+  customizing a category needs no migration.
+- External classifiers (OpenAI, image moderation) are reference adapters in `examples/`, not
+  shipped or loaded code — the gem core forces no service dependency on apps that never use it.
+- All "DSA-compliant" / "App Store compliant" language reframed to **DSA-aligned primitives**:
+  the gem ships the mechanisms the law and the stores require; your policies, response times,
+  and operations are still yours.
+
+### Upgrading from 0.x
+
+- The 0.x profanity validator still loads: `validates :field, moderate: true` continues to work
+  via compatibility shims, so existing apps keep validating. To adopt 1.0, add
+  `has_moderation_capabilities` to your user model and `reportable` / `moderates` to your
+  content models, run `rails generate moderate:install`, and migrate.
+
 ## [0.1.0] - 2024-11-03

+- Initial release (profanity validator).

+  spec.description = "moderate is a complete Trust & Safety and content moderation engine for Ruby on Rails apps with user-generated content (UGC) — social apps, marketplaces, dating, communities, forums, comments, reviews, and chat. It bundles the four things every UGC app needs behind one data model and one set of hooks: abuse reporting (report posts, comments, profiles, listings, messages, and other users), bidirectional user blocking behind a single enforced source of truth, pre-publication content filtering for profanity, slurs, hate, spam, harassment, and objectionable or NSFW text and images in off/block/flag modes, and an audited moderation queue with locked resolve/dismiss/remove-content/ban decisions, internal appeals, and statement-of-reasons notifications. Filtering uses a tiny classify(value) => Result adapter contract: a fast, offline, multilingual wordlist/profanity/bad-word blocklist ships as the zero-dependency default, and you bring your own classifier (OpenAI omni-moderation, AWS Rekognition image/NSFW detection, Google Perspective, or self-hosted) as an optional reference adapter, never a forced dependency. moderate also ships primitives aligned with the EU Digital Services Act (DSA notice-and-action, statement of reasons, appeals, transparency) and with the Apple App Store (Guideline 1.2) and Google Play user-generated-content review rules that get apps rejected without report/block/filter — the mechanisms, not a compliance certificate. It is a mountable, UI-agnostic Rails engine with no hard dependencies beyond ActiveRecord, ActiveSupport, Railties, and GlobalID, and optionally auto-integrates with madmin, goodmail, telegrama, noticed, and rails_cloudflare_turnstile — a modern, full-stack alternative to single-purpose Rails profanity filters like obscenity and profanity-filter."

Subject: [PATCH 12/15] Rename macros to has_reporting_and_blocking /
 has_reportable_content (clean, no aliases) + Report#resolve!/dismiss! +
 transparency opt-in
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- has_moderation_capabilities -> has_reporting_and_blocking; reportable -> has_reportable_content.
  No back-compat aliases — pre-1.0, clean rename. All call sites, tests, dummy app, docs,
  CHANGELOG, and comments updated; the non-macro reportable surface (Moderate::Reportable,
  reportable_fields, the polymorphic association, reportable: kwargs) is untouched.
- Add Report#resolve!(by:, **) and Report#dismiss!(by:, note:) delegators to
  Moderate::Services::ResolveReport so the documented one-liner API is real (+ test).
- Public Art. 24 transparency report is now opt-in: config.transparency_report_enabled
  (default false); the controller 404s when disabled.

 > [!NOTE]
-> `moderate` is **UI-agnostic by design**: most Trust & Safety lives in *admin* surfaces, so the gem ships the **primitives** (models, services, helpers, controller concerns) and lets you **bring your own UI**. It plugs into [`madmin`](https://github.com/excid3/madmin) (or any admin) in minutes — see [Admin & moderation queue](#-admin--the-moderation-queue). It also snaps into the rest of the ecosystem: [`goodmail`](https://github.com/rameerez/goodmail) for decision emails, [`telegrama`](https://github.com/rameerez/telegrama) for admin alerts, and [`noticed`](https://github.com/excid3/noticed) for multi-channel notifications — all through one `notify` hook.

-## Why this gem exists
-
-Every app with user-generated content eventually faces the same wall. A user posts something vile, another user wants them gone, Apple rejects your build for "no way to report objectionable content," and a Spanish lawyer emails you about the Digital Services Act. So you start bolting on a `reports` table, a `blocks` table, a profanity regex, an admin page, a "notify the reporter" email… and it's suddenly a sprawling, half-correct subsystem entangled with your core app.
-
-It's the kind of plumbing nobody wants to build, everybody rebuilds, and almost everybody ships *incomplete* — which is exactly what gets apps rejected from the stores and exposed under the DSA. `moderate` is the single, opinionated, batteries-included source of truth for it:
-
-- **Report** users and content (in-app), with evidence snapshots and a real decision workflow.
-- **Block** users (bidirectional), enforced everywhere a blocked pair could reconnect.
-- **Filter** text and images before they're posted (`:off` / `:block` / `:flag`), with pluggable backends — a built-in offline wordlist, plus ready-to-copy reference adapters in `examples/` (OpenAI, AWS Rekognition) or your own.
-- **Moderate** from a queue: remove content, ban users, dismiss, all audited.
-- **Align** with the core DSA / store-review mechanisms: notice-and-action (Art. 16), statement of reasons (Art. 17), internal appeals (Art. 20), transparency counters (Art. 24); Apple Guideline 1.2 and Google Play UGC requirements.
-
-It works standalone, and gets better with the rest of the ecosystem.
-
-## What `moderate` does and doesn't do
-
-**Does:**
-- User & content **reporting** (in-app) + a public **DSA legal-notice** intake form.
-- **Blocking** with a single source-of-truth query you enforce in search, messaging, profiles, anywhere.
-- **Pre-publication content filtering** with three modes and pluggable adapters — the built-in offline wordlist (text), plus image/LLM moderation via reference adapters you register (see `examples/`).
-- A **moderation queue** with audited resolve / dismiss / remove-content / ban actions.
-- **Appeals**, **statement-of-reasons** notifications, and **transparency** aggregation for the DSA.
-- Optional **audit** and **notification** hooks that fan out to your mailer / admin alerts / push.
-
-**Doesn't** (on purpose — these are other tools' jobs):
-- Authentication / current-user (that's Devise — you tell `moderate` your user class).
-- Sending the actual emails/push (that's [`goodmail`](https://github.com/rameerez/goodmail) / [`noticed`](https://github.com/excid3/noticed) — `moderate` just emits events).
-- The admin UI chrome (that's [`madmin`](https://github.com/excid3/madmin) / your app — `moderate` gives you the data + primitives).
-- A bulletproof ML classifier out of the box (the default text filter is a fast, multilingual wordlist; bring an LLM/image adapter when you want one).

Filtering uses a tiny classify(value) => Result adapter contract: a fast, offline, multilingual wordlist/profanity/bad-word blocklist ships as the zero-dependency default, and you bring your own classifier (OpenAI omni-moderation, AWS Rekognition image/NSFW detection, Google Perspective, or self-hosted) as an optional reference adapter, never a forced dependency. moderate also ships primitives aligned with the EU Digital Services Act (DSA notice-and-action, statement of reasons, appeals, transparency) and with the Apple App Store (Guideline 1.2) and Google Play user-generated-content review rules that get apps rejected without report/block/filter — the mechanisms, not a compliance certificate.

Filtering uses a tiny classify(value) => Result adapter contract: a fast, offline, multilingual wordlist/profanity/bad-word blocklist ships as the zero-dependency default, and you bring your own classifier (OpenAI omni-moderation, AWS Rekognition image/NSFW detection, Google Perspective, or self-hosted) as an optional reference adapter, not a forced dependency. moderate also ships primitives aligned with the EU Digital Services Act (DSA notice-and-action, statement of reasons, appeals, transparency) and with the Apple App Store (Guideline 1.2) and Google Play user-generated-content review rules that get apps rejected without report/block/filter. It is a mountable, UI-agnostic Rails engine with no hard dependencies beyond normal Rails stuff."

Subject: [PATCH 13/15] docs: reflect current API + make documented one-liners
 real
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- README/docs updated to the renamed macros (has_reporting_and_blocking /
  has_reportable_content) and the transparency-report opt-in.
- Make the documented plain-English admin API real: Appeal#uphold!(by:, note:) /
  Appeal#reject!(by:, note:) delegate to Moderate::Services::ResolveAppeal (matching
  Report#resolve!/#dismiss!); add tests.
- Add Moderate.transparency(from:, to:) — the DSA Art. 24 aggregation the docs
  reference and a host needs to publish its own report now that the public page is
  opt-in; the controller renders it; compliance.md citations fixed; add a test.
- compliance.md: drop adjective backticks on 'reportable', repoint phantom test
  citations at the real transparency test.

 If your app runs inside Hotwire Native / Turbo Native, remember that native path configuration is host-owned.

Play wants you to be able to report **and** block **both** a person and a thing. `moderate` covers all four cells because a user model with `has_reporting_and_blocking` is *also* reportable, and blocking is enforced over content via `blocked_ids_for`. If you only made content reportable and never made users blockable, you'd pass Apple's spot check and still fail Play's policy.

Subject: [PATCH 14/15] docs(README): production-realistic filtering examples
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Make the two filtering examples distinct and true-to-API: the teaser now shows the
production case (OpenAI moderation, :flag, async→queue, with the one-line
register_adapter), and Quickstart shows the zero-setup case (built-in :wordlist,
:block). Different model/mode/adapter in each.

Subject: [PATCH 15/15] docs(compliance): repoint test-file citations at real
 files

Every [gem] evidence citation in docs/compliance.md now resolves to a real test
(the doc had ~20 aspirational/namespace-stale paths). Each was repointed to the
test that actually exercises that guarantee (verified): decision guarantees ->
resolve_report_test, appeal guarantees -> resolve_appeal_test, snapshot/user-
reportable -> report_test, blocked_ids -> blocking_test, filter modes ->
content_filtering_test, report-link/report! -> reporting_test, etc.

   spec.summary = "Let your Rails users report content and block each other (Trust & Safety)"
-  spec.description = "moderate is a complete Trust & Safety and content moderation engine for Ruby on Rails apps. Trust & Safety (T&S) is the system within an app that lets users report abusive content, block each other, filter objectionable text and images before they're posted (profanity, bad words, nudity, etc.), and run a moderation queue your admins actually use. It also allows you to easily plug in automated AI moderation systems like OpenAI Moderation or AWS Rekognition to quickly filter, flag and/or automatically block harmful content (text or image). Any app with user-generated content (UGC) needs this: social apps, marketplaces, dating, communities, forums, comments, reviews, chat, etc. The moderate gem bundles the four things every UGC app needs behind one data model and one set of hooks: abuse reporting (report posts, comments, profiles, listings, messages, and other users), bidirectional user blocking behind a single enforced source of truth, pre-publication content filtering for profanity, slurs, hate, spam, harassment, and objectionable or NSFW text and images in off/block/flag modes, and an audited moderation queue with locked resolve/dismiss/remove-content/ban decisions, internal appeals, and statement-of-reasons notifications. Filtering uses a tiny classify(value) => Result adapter contract: a fast, offline, multilingual wordlist/profanity/bad-word blocklist ships as the zero-dependency default, and you bring your own classifier (OpenAI omni-moderation, AWS Rekognition image/NSFW detection, Google Perspective, or self-hosted) as an optional reference adapter, not a forced dependency. moderate also ships primitives aligned with the EU Digital Services Act (DSA notice-and-action, statement of reasons, appeals, transparency) and with the Apple App Store (Guideline 1.2) and Google Play user-generated-content review rules that get apps rejected without report/block/filter. It is a mountable, UI-agnostic Rails engine with no hard dependencies beyond normal Rails stuff."
