Structural, adapter and Codex checks are +**fatal**; the content drift guards **warn**. + +### Package subpath existence — `scripts/validate-package-subpaths.sh` (warn) + +Every other drift guard asserts that a string should *not* appear. This one is the other direction, +and the only guard that knows what a package is. It extracts each `@cratis//` the +corpus names — fenced blocks, inline spans and table cells alike — from `.cratis/ai/rules`, `.cratis/ai/skills`, +`.cratis/ai/agents` and `.cratis/ai/prompts`, then resolves it against the `exports` map of the package installed +in `node_modules`. The exports map is exact and machine-readable, so a miss is a genuine miss. +`.cratis/ai/hooks` is deliberately *not* one of the default roots — this page names bogus subpaths as +examples, and a guard that reports its own documentation is a guard people switch off. + +It exists because nothing in the repository could catch documenting +`@cratis/components/Notifications` (a subpath that first ships in **3.0.0**) while the pin is +**2.6.1**. A prose-pattern matcher has no notion of a package, a version, or an exports map; a +developer following the corpus got a module-resolution failure. + +**Warn, never fail — the tradeoff.** The observation is exact but the conclusion is not: "the corpus +names an API that does not exist" and "this repository is pinned behind the version the corpus +documents" look identical from the exports map. This script propagates to every Cratis repository, +and the `ai-corpus` CI job checks out the tree and installs nothing — so failing would be a +permanent no-op in CI while turning repos red locally for their own dependency pin. The warning +names the file, the line and the installed version, and leaves the judgement to a human. + +> **What this repository is.** `Cratis/AI` is a corpus of markdown, JSON and a little +> JavaScript — it has no `Source/`, no `.slnx`, no `package.json` and no C# or TypeScript +> project of its own. Every `.cs` / `.ts` / `Source/**` reference below describes what the +> hooks do in a **consuming** repository. Here they are silent, which is the designed +> behavior, not a broken setup. + +**Silent when it cannot judge.** No `jq`, no `node_modules`, a package this repository does not +depend on, or a package published without an `exports` map: skipped without a word. "Not installed" +is not a finding. + +**Version-qualified lines are not drift.** The corpus deliberately documents some 3.0.0+ APIs +against a 2.x pin, marked inline as `(**≥ 3.0.0**)`. A reference is cleared when a line mentioning +it in the same file also carries a version — a dotted number, an `N.x`, or either inequality +spelling. Qualification is judged per *(file, reference)* rather than per line, because the corpus +states a requirement once and then mentions the subpath again unqualified nearby; per-line matching +would fire on exactly the lines someone had just fixed correctly. The check is deliberately generous +in the same direction: it would rather miss a stale line than warn about a correct one. + +**What it deliberately does not check.** Named imports (`import { Toaster } from '…'`) are Tier 2's +job, below; .NET types named in prose or in a C# type position are Tier 3's. This tier checks module +specifiers, nothing else. + +Run it standalone, optionally over other roots, and add `CRATIS_HOOKS_SUBPATH_REPORT=1` to see every +reference and how it resolved rather than only the failures. It invokes Tier 3 before its own gates +and Tier 2 after its own work, over the same roots, so the single call site in +`validate-ai-setup.sh` gets all three. + +### Named import existence — `scripts/validate-package-imports.sh` (warn) + +Tier 2, and the reason it exists is that Tier 1's answer is not the whole question: a subpath that +resolves says nothing about the *names* imported through it. For every +`import { A, B } from '@cratis//'` in the corpus — single-line, brace-on-its-own-line, +`import type`, `A as B` (the *imported* name is what has to exist), trailing `//` comments — it +checks each identifier against the `.d.ts` closure of the installed package and warns about the ones +that are not there. `Toaster`, `toastCommandResult`, `PasswordField`, `RatingField` and the rest are +real APIs of `@cratis/components` **3.0.0** and absent from **2.6.1**; Tier 1 caught the three +*subpaths* that moved with them, and the twelve *names* were found only by a human reading package +internals. + +**Deliberately permissive, and here is the price.** A name passes when it appears as a *word +anywhere* in the package's `.d.ts` closure — not only in an export position, not only behind the +subpath it was imported from — and the closure follows `export … from ''` re-exports +one level out to another installed package. Intra-package barrels (`export * from './X'`) need no +following, because the whole tree is read either way. That admits names the package merely +*references* (an imported PrimeReact symbol, a name in a doc comment) and it will not notice a name +imported from the wrong subpath of the right package. The trade is deliberate: a false warning +trains people to ignore the guard, a missed one costs a stale line. Measured over the corpus's 85 +import statements / 134 bindings / 38 distinct *(package, name)* pairs plus a 36-pair all-valid +probe: **zero false positives**, and it still flags all twelve of the 3.0.0 names above when they are +written unqualified. + +**Same warn-only, same silence, same version rule as Tier 1.** No `jq`, no `node_modules`, a package +this repository does not depend on, or a package that ships no `.d.ts`: skipped without a word. A +name is cleared when any line in the same file that mentions it also carries a version — judged per +*(file, name)*, for the same reason Tier 1 judges per *(file, reference)*. + +**What it deliberately does not check.** Identifiers that never appear inside an `import { … }`: +prose mentions, JSX usages, and C# type positions are all invisible. It reads TypeScript import +statements, nothing else. + +Run it standalone over any roots, and add `CRATIS_HOOKS_IMPORT_REPORT=1` to see every binding and how +it resolved rather than only the failures. + +### .NET type existence — `scripts/validate-type-references.sh` (warn) + +Tier 3, and the only tier that reads .NET rather than TypeScript. Tiers 1 and 2 both start from an +`import` statement, so a type the corpus names *only* in prose and in C# type positions is invisible +to both. That is exactly how `ReactorSideEffect` survived: never a module specifier, never an import, +told readers to return it from a reactor, shown with object-initializer syntax — and never a type in +any Chronicle release. Someone following the corpus wrote code that does not compile. + +**The index.** Every `Cratis*` version pinned in `Directory.Packages.props` — or, in the corpus +repository itself, in the tracked pin list `scripts/cratis-nuget-pins.txt`, which names the exact +product versions the skills verify against — plus the Cratis packages those pull in (`Cratis` is a +metapackage), resolved against the local NuGet cache. A pin moves only together with the skill +whose verified version moved. + +**Exit codes.** `0` ran (warnings, if any, are on stderr); `1` a `--self-test` expectation failed; +`2` could not run — no pin source, no NuGet cache, or an index that came up empty — with the reason +on stderr. "Ran and found nothing" and "never looked" are different verdicts +(`exit-codes-and-wrappers.md`), and this guard spent its first lifetime erasing that difference by +exiting `0` at the `Directory.Packages.props` gate in a repository that has none (#287). + +**Self-test.** `--self-test` seeds the motivating fabrication (`ReactorSideEffect`, in prose, in +attribute position, beside the real names it must be distinguished from) into a scratch corpus and +fails unless the guard names it and keeps the real types silent. Run it after any change to the +extraction rules, the pin list, or the allowlist — a guard that can pass vacuously is worse than no +guard (`guards-and-fuses.md`). Each package's +`lib/**/*.xml` carries `` — a complete machine-readable type +list — and every other identifier the docs mention is kept as a second, permissive accept list, in +the same spirit as Tier 2's "a word anywhere in the `.d.ts` closure". Names the corpus itself +declares, and names declared in the consuming repository's own `Source/**/*.cs`, are accepted too: a worked +example that writes `public record AuthorRegistered(…)` before using it is not documenting a +framework API. A curated allowlist covers the rest — see below. + +**Why it is narrow, and what that cost.** The naive version of this check is the reason the whole +tier nearly did not ship. Of the **1279** distinct PascalCase names it reads across 151 corpus files, +**599 — 47% — resolve nowhere**, because the corpus legitimately invents domain examples +(`AuthorRegistered`, `IAuthorService`), placeholders and prose nouns. A guard that cries wolf 599 +times gets switched off, and then it protects nothing. So only two constructs are ever reported: + +| Construct | Why it is safe | Measured | +|---|---|---| +| **Attribute position** — `[Name]`, `[Name]`, `[Name(…)]` inside an inline code span or a fenced `csharp` block | attribute brackets are unambiguous C#, and a markdown link cannot live inside a code span, so the syntax alone identifies an API reference; `Name` and `NameAttribute` both count | 686 occurrences, 61 distinct names | +| **Framework-adjacent type token** — any other PascalCase token in a code span or a fenced `csharp` block that resolves nowhere **and** is a strict PascalCase-word-boundary *prefix* of a real Cratis type name | that is the fabrication signature: a half-remembered real family of names with a member coined that was never minted. `ReactorSideEffect` is a prefix of `ReactorSideEffectFailure`; `AuthorRegistered` is a prefix of nothing Cratis ships | takes the 599 unresolved down to **2** | + +Both remaining names — `ICommand` and `IQuery`, which do not exist — are cleared by the absence rule +below, because the corpus's own point about them is exactly that. **Zero warnings on the real +corpus.** + +**Constructs measured and rejected.** Each was extracted over the whole corpus and its unresolved +names counted before being dropped: `new TypeName` in a fenced `csharp` block (**17** false positives — +example events are constructed but never declared), `IInterfaceName` in a fenced `csharp` block (**17** — +invented example services like `IOrderRepository`), the same in an inline code span (**23** — +TypeScript interfaces and shouty prose such as `IMPORTANT`), and in bare prose (**2**, including the +plural `IDs`). None of them survives the "precision over recall" test on its own. They are all still +*read*; they simply have to earn a warning through framework-adjacency instead of through syntax. + +**Three structural exclusions, no allowlist needed.** A token is skipped when it is preceded by `.` +(a member, not a type), when it is ALL-CAPS (`PII`, `IMPORTANT`), and when it is written as +`` — the corpus's `//` idiom, distinguished from a generic +argument list by the character before the `<`, which in C# is always an identifier character. + +**Same warn-only and same version rule as Tiers 1 and 2, plus one of its own.** A name is cleared +when any line in the same file that mentions it carries a version, *or* says the thing does not +exist — `does not exist`, `no longer`, `never use`, `removed`, `deprecated`, `there is no` and +friends. Part of this corpus's job is naming APIs that are **not** real, and warning about a line +whose entire point is that the type is fictional would be the most annoying false positive of all. +The cost is stated plainly: reintroduce a fabrication into a sentence containing one of those +phrases and the guard stays quiet. + +**Silent when it cannot judge.** No `Directory.Packages.props`, no local NuGet cache, or a cache +holding none of the pinned versions: skipped without a word. It needs no `jq` and no `node_modules`, +which is why Tier 1 invokes it *above* its own gates rather than beside the Tier 2 call — a backend- +only repository must still get this check. It adds about 1.4 s to `validate-ai-setup.sh`. + +**The allowlist — `scripts/type-references-allowlist.txt`.** Thirteen entries, each with a written +justification: ASP.NET Core and BCL attributes that live in ref packs (which ship no XML docs at +all), Orleans and `Microsoft.Extensions.*` attributes from packages that ship none either, `[CliCommand]` +/ `[CliExample]` from the separate `Cratis/cli` repository, the Chronicle **Kernel**'s `WellKnown`, +and `@cratis/fundamentals`' TypeScript `JsonSerializer`. Every one was verified real before being +listed. An entry is a small lie the guard tells itself, so prefer widening the index whenever that +is possible, and never add a name you have not confirmed exists. + +**What it deliberately does not check.** TypeScript — that is Tiers 1 and 2. Members, methods and +properties: `Provide()`, `.AutoMap()` and `EventStoreName.NotSet` are all invisible, and a fabricated +*member* on a real type would pass. And a fabricated type that is not a prefix of any real Cratis +name is invisible too — the adjacency filter is what buys the precision, and it is also the ceiling +on the recall. + +Run it standalone over any roots, and add `CRATIS_HOOKS_TYPE_REPORT=1` to see every distinct name and +how it resolved rather than only the failures. + +## Configuration is data, not code + +Neither the pattern list nor the gate commands live in a script. A consuming repository +customises both without forking anything: + +| File | Purpose | +|---|---| +| `scripts/cratis-patterns.json` | shipped pattern set; its header `$comment` documents every field | +| `scripts/cratis-patterns.local.json` | optional; merged over the above by `id` — add patterns, or set `"enabled": false` to silence one | +| `scripts/quality-gates.json` | shipped gates; `changed` globs decide when a gate runs, `requires` and `workingDirectoryFrom` decide whether it *can* | + +A gate whose `requires.commands` are not on `PATH`, whose `requires.paths` do not exist, or whose +`workingDirectoryFrom` matches nothing in the repository, is a **no-op with a message on stderr** +rather than a failure — that is how a repository with no .NET solution or no frontend stays quiet. + +**No shipped gate names a product's file.** A default that did would activate in exactly one +repository and silently no-op in every other, which is the worst of both: it looks configured and +checks nothing. So the .NET and frontend gates state *what kind of project* they build and let the +gate script find it — `workingDirectoryFrom: ["*.slnx", "*.sln", "**/*.slnx", "**/*.sln"]` runs +`dotnet build` in whichever directory holds the repository's own solution, preferring one at the +root because the globs are tried in order. The frontend gates discover `package.json` the same way. +The same shipped file therefore activates in an application repository, activates in a framework +repository, and stays quiet in a corpus-only repository like this one, which has no project at all. + +**Overriding it, in order of increasing force.** Set `workingDirectory` on a gate to pin one of +several candidate projects; drop a `quality-gates.json` of your own in place of the shipped one; or +point `CRATIS_HOOKS_GATES` at a file anywhere. None of them requires forking the script. + +**Profile note.** The C# patterns are application-profile and scoped to `Source/**/*.cs`, which is +the application source root [`../rules/general.md`](../rules/general.md) documents — not a path in +this repository, which has no C# at all. A framework-profile repository (Arc, Chronicle, +Fundamentals, Components — see [`../rules/framework.md`](../rules/framework.md)) has no vertical +slices and should disable them in its `cratis-patterns.local.json`; a repository whose application +source root is not `Source/` re-scopes the `paths` globs there too. + +**One property gates the proxy generator.** The generator's MSBuild target is +`Condition="'$(CratisProxiesOutputPath)' != ''"`, so clearing that property with +`-p:CratisProxiesOutputPath=` is the *only* way to make it no-op. There is no +`DisableProxyGenerator` property — MSBuild silently accepts unknown `-p:` names, so passing one +looks like it works and changes nothing. A consuming repository's build workflow should split the +two configurations the way the shipped gates do: Release clears the path, Debug does not, because +`general.md` makes the Debug build the canonical trigger for regenerating the TypeScript proxies +the frontend phase depends on. + +## Escape hatches + +Each is an explicit, auditable opt-out — none of them is a default. + +| Variable | Effect | +|---|---| +| `CRATIS_HOOKS_ALLOW_PROTECTED_WRITES=1` | allows one protected write; this is the "unless explicitly asked" case for dependency manifests | +| `CRATIS_HOOKS_SKIP_SCAN=1` | disables the pattern pass | +| `CRATIS_HOOKS_SKIP_GATE=1` | disables the quality gate | +| `CRATIS_HOOKS_GATE_DRYRUN=1` | prints which gates would run, and why, then exits 0 | +| `CRATIS_HOOKS_PATTERNS=` | replaces the pattern file | +| `CRATIS_HOOKS_GATES=` | replaces the gate file | +| `CRATIS_HOOKS_SUBPATH_REPORT=1` | prints every `@cratis/*` subpath reference and how it resolved, not only the failures | +| `CRATIS_HOOKS_IMPORT_REPORT=1` | prints every `@cratis/*` named import binding and how it resolved, not only the failures | +| `CRATIS_HOOKS_TYPE_REPORT=1` | prints every .NET type/attribute name the corpus mentions and how it resolved, not only the failures | + +## Design constraints + +- **POSIX-safe bash**, `set -euo pipefail`, quoted expansions, no `eval`.

They never pass through a shell. +- **`jq` is the only dependency.** Every script + degrades to a silent no-op when it is missing — a hook must never break a session. +- **Fail safe.** Malformed config, empty stdin, a missing file, a binary file, a file over 2 MB: + all exit 0 silently. +- **No secrets, no file dumps.** Gate output is capped at `maxOutputLines`; the pattern pass + prints a path, a line number and a fixed message — never file content. +- **No re-entry.** The `Stop` hook returns immediately when `stop_hook_active` is true, so a + blocked turn cannot loop. +- **Each pattern fires once per file per session**, tracked under + `${TMPDIR}/cratis-hooks//`, so a long edit loop cannot flood context. +- **The gate never edits code.** It builds, tests and lints. The one side effect is that a Debug + build regenerates TypeScript proxies, which is the documented purpose of that build. + +## Verifying a change + +The scripts read hook JSON on stdin, so they are directly testable: + +The pattern pass and the gate both read the repository they are pointed at, so testing them means +pointing them at a repository that *has* the thing under test.

A class that fetches data, transforms it, validates it, and sends an email has four reasons to change. When any of those concerns shifts, you have to touch — and risk breaking — all the others. + +**Rules:** +- A class or method that requires a comment explaining what each section does is a sign it should be split. +- Methods longer than ~20 lines are a signal they are doing too much — extract collaborators or helper methods. +- If a type needs collaborators from two unrelated domains, question whether it has two responsibilities. +- Follow the [File Size Guideline](#file-size--200-line-guideline) below. + +## Open/Closed Principle + +Types should be **open for extension, closed for modification**. Once a type is in use, changing its internals to support new behavior risks breaking existing callers. Instead, design extension points — interfaces, strategies, event hooks — that allow new behavior to be added without touching existing code. + +**Rules:** +- Prefer strategy interfaces over `switch`/`if-else` chains that grow over time. +- Design public APIs as contracts (interfaces/records) rather than concrete implementations. + +## Separation of Concerns + +Each layer and each module should own exactly one concern. Mixing concerns — for example, querying the database and formatting the HTTP response in the same method — creates entanglement that makes both concerns harder to change or test independently. + +**Rules:** +- Keep domain logic out of infrastructure — domain types must not reference infrastructure or transport concepts directly. +- Keep infrastructure out of domain logic — handlers and domain types express intent; they delegate to collaborators for persistence, messaging, and I/O. + +## Low Coupling + +Coupling is the degree to which one module depends on the internals of another. High coupling means a change in one place forces changes everywhere else. Low coupling means modules can evolve independently. + +**Rules:** +- Depend on abstractions, not on concrete implementations. +- Avoid reaching through an object to call methods on its dependencies — this is a sign of tight coupling. +- Limit the number of dependencies a single type takes — more than four or five is a signal it is doing too much. +- Never reference types from unrelated features directly; go through a shared contract or event instead. + +## High Cohesion + +Cohesion measures how closely related the responsibilities within a module are. A highly cohesive class has all its methods and properties working together toward a single goal. A low-cohesion class is a collection of unrelated utilities that happen to live in the same file. + +**Rules:** +- Group code by feature, not by technical role — everything for a behavior belongs together. +- If you find yourself writing methods in a type that use completely different sets of fields or dependencies, the type likely needs to be split. +- Utilities and helpers are acceptable only when the operations they provide are genuinely shared across features; otherwise, keep logic in the feature that owns it. + +## File Size — 200-Line Guideline + +A file exceeding **200 lines** is a strong signal that it contains too many responsibilities. This is not a hard limit — some files are legitimately longer — but whenever you find yourself adding to a file that already approaches this size, stop and ask: can this be split? + +**Rules:** +- When a file crosses 200 lines, look for natural split points: a sub-concept that could become its own type, a behavior that could move to a collaborator, or a section that belongs in a different layer. +- Aim for files that can be understood in a single reading without scrolling. +- Instruction and documentation files follow the same principle — a guide over 200 lines usually contains multiple distinct topics that deserve their own files. + +## Cross-Cutting Concerns + +Cross-cutting concerns — logging, validation, authorization, error handling, metrics, caching — affect many parts of the system but belong to none of them. Scattering them through business logic creates noise and duplication. Centralizing them in infrastructure keeps domain code clean. + +**Rules:** +- Never write logging or authorization checks inside domain logic — apply them at the infrastructure boundary. +- Never duplicate error-handling or retry logic — centralize it in a pipeline, middleware, or decorator. +- When you notice the same infrastructural pattern appearing in two or more places, extract it into a shared cross-cutting mechanism rather than duplicating it. diff --git a/.cratis/ai/rules/code-quality.typescript.md b/.cratis/ai/rules/code-quality.typescript.md new file mode 100644 index 0000000..38524b7 --- /dev/null +++ b/.cratis/ai/rules/code-quality.typescript.md @@ -0,0 +1,90 @@ +--- +applyTo: "**/*.ts,**/*.tsx" +paths: + - "**/*.ts" + - "**/*.tsx" +--- + + +# Code Quality — TypeScript + +TypeScript/React-specific applications of the general [Code Quality](./code-quality.md) principles. + +## Composition over Inheritance + +React is built on composition — components accept children, hooks compose other hooks, and higher-order utilities wrap behavior.

Directive asides can also take a Starlight icon attribute, but verify the icon name first; a bad aside icon fails the build. + +## Code blocks + +- Always tag the language: `csharp`, `tsx`, `typescript`, `bash`, `yaml`, and so on. +- Expressive Code supports useful metadata such as ``title="Program.cs"`` and line/text markers. Use them to orient the reader or focus a diff, not to decorate every snippet. +- DocFX-era aliases include `env`, `pdl`, `ebnf`, `pql`, `gitignore`, `flow`, and `screenplay`; use a real language where one exists. +- Dedent snippets to column zero while preserving their internal indentation. +- Show both sides of a full-stack contract, but do not automatically hide sequential C#→generated-TypeScript explanations behind tabs. Use `FullStackTabs` only when the snippets are alternatives that remain understandable independently. +- The converter's DocFX-alert and link rewriting is not fully code-fence-aware. Literal `> [!NOTE]`, Markdown-link targets, or `href="…"` examples can be rewritten; inspect the synced output when documenting those syntaxes. + +## Tables, images, links, and diagrams + +- Use GFM tables with a separator row and a blank line before the table. `remarkGfm` in the Documentation site's Astro config is load-bearing for `.mdx`; raw pipe text in a rendered page indicates that integration is missing or degraded. +- Keep images beside the source page, use meaningful alt text, and rely on the site's click-to-zoom behavior. +- In product source, relative links to files keep their real `.md` or `.mdx` extension. The converter strips either extension for the public route. Directory URLs end in `/`. +- Site-level MDX uses clean root-relative routes such as `/arc/backend/commands/`. Cross-product links are also root-relative. +- Link text describes the destination; `here`, `click here`, and `see documentation` are hard lint errors. +- Use `mermaid` for architecture, sequence, flow, and state diagrams.

Arc.Core does **not** depend on Chronicle. +- **Chronicle** — the event-sourcing engine. `Source/Kernel` (the engine: **Orleans grains**, event sequences, observers/projections/reducers, storage providers — MongoDB and others), `Source/Clients` (the client SDKs incl. `DotNET` and `Testing`), `Infrastructure`, `Tools`, `Workbench`. The kernel is the deep, performance- and consistency-critical core. +- **Components** — the React component library on PrimeReact. `Source//` folder per component (`CommandDialog`, `DataPage`, `DataTables`, …) with Storybook stories; published as `@cratis/components`. (Application rules *consume* these components; here you *build* them.) + +Repo conventions follow from this: `Source/DotNET` + `Source/JavaScript` for dual-stack libraries; `Kernel` vs `Clients` for Chronicle; a folder-per-component library layout for Components. Match the structure of the area you are editing — do not introduce app-style layouts. + +## Framework-contributor principles + +- **Public API design is the product.** These libraries are consumed by every Cratis app, so the **Lovable APIs** value (`general.md`) is paramount: sane defaults, convention over configuration, extensible/overridable, minimal boilerplate. Design the API the app developer will love before the implementation. +- **Backward compatibility is a contract.** A change to a public type, attribute, interface, or generated-proxy shape is a breaking change for every downstream app — label PRs by semver impact (`major`/`minor`/`patch`) and treat removals/renames of public surface as `major`. +- **Convention discovery is built here.** `IInstancesOf` / `IImplementationsOf`, attribute-based discovery, and source generation are the mechanisms the framework *provides*; use them internally too rather than hand-registration where a convention fits. +- **Source generators / analyzers** (Arc's proxy generator, Fundamentals) follow Roslyn conventions; their output is consumed verbatim by apps, so treat generated shape as public API. +- **Orleans grains** in the Chronicle kernel follow `orleans.md`. +- **An alternate implementation of an interface must match the primary one's *semantics*, not just its signature.** Chronicle ships several implementations of the same storage interfaces (MongoDB, SQL, in-memory) and the in-memory ones exist precisely so the real kernel code paths can run without infrastructure. When you touch one, **diff it against the persistent implementations** — the signature tells you nothing about the contract. The specific trap: query criteria carry **sentinels meaning "do not narrow"** (`EventSourceId.Unspecified`, `EventSourceType.Unspecified`/`Default`, `EventStreamType.All`, `EventStreamId.Default`, an empty event-type set). Callers asking for "everything" pass those sentinels, never `null`, so a plain `is not null` check narrows every row away and the read silently returns nothing. A divergence here does not fail — it makes specs pass vacuously, which is worse. +- **A stub that silently succeeds is a bug, not a placeholder.** An unimplemented method returning `Task.CompletedTask`/an empty result lets a spec assert on work that never happened. Implement it, or make it fail loudly — never leave it quietly lying. +- **Specs** use `Cratis.Specifications` (the `Establish`/`Because`/`should_` BDD style) with NSubstitute — the same philosophy as apps, without the Arc/Chronicle `*Scenario` app-testing helpers. +- **Treat "no spec touches this public API" as a defect in itself.** Public surface with zero coverage is where silent breakage lives — an entire read surface, including two shipped assertion helpers, was once dead in `Cratis.Chronicle.Testing` because nothing ever called it. When adding public API, add at least one spec that exercises it end to end. + +## Quality gates (framework) + +- Build clean (Debug and Release) with **zero warnings, zero errors**. +- Specs pass for affected projects (C# via `dotnet test`; TS packages via their test command; Components also `build-storybook`). +- For public-facing changes (APIs, attributes, generated output, component props): update the product documentation and verify it. +- Match the repo's existing patterns; when a deep architectural question isn't answered by the universal rules or this file, consult the **repo's own docs/CONTRIBUTING** or ask — do not infer framework internals from a single call site. + +## Depth lives in the repo + +This file is the cross-cutting framework-contributor baseline.

A `[Command]` `Handle()` does not *have* to append events — it can return a response, return `void`, or work through injected services. The event-sourcing behavior (a returned event gets appended; `EventForEventSourceId`; "never inject `IEventLog`") comes from the **Arc + Chronicle** integration. This application is event-sourced, so the slice guidance assumes event-sourced commands — read the event-centric rules as the *house default for this app*, not universal Arc laws. + +The framework is convention-over-configuration. **Idiomatic Cratis is the goal — not custom abstractions over it.** When something is unclear, prefer the Cratis convention; do not invent.

If an API feels awkward, it is wrong. +- **Easy to do things right, hard to do things wrong** — convention over configuration; artifact discovery by naming/attributes; minimal boilerplate. The framework guides you into the pit of success. +- **Events are facts** — immutable records of what happened. Past tense, one purpose, never ambiguous. If you reach for a nullable property on an event, you need a second event. +- **Strongly-typed primitives are the foundation — get them right first.** The most important, load-bearing decisions in every slice are the domain primitives: `ConceptAs` value types and `EventSourceId` identities (never raw `Guid`/`string`/`int` for a domain value); `ConceptValidator` for invariants that travel with a value everywhere it appears; `CommandValidator` for command-level rules; and past-tense, self-describing `[EventType]` names. These are not boilerplate or an afterthought — they are what makes the model type-safe end to end, the rules enforceable in one place, the events trustworthy forever, and the generated proxies meaningful. Treat naming and typing them precisely as the highest-value craftsmanship in the codebase; a slice built on sloppy primitives is wrong no matter how good the rest is. +- **High cohesion through vertical slices** — everything for a behavior lives together: backend, frontend, specs. Navigate by feature, not by technical layer. +- **Full-stack type safety** — shared models flow from C# through proxy generation to TypeScript. End-to-end typing without manual synchronization. +- **Specialization over reuse** — focused, purpose-built read models over one model reused across conflicting scenarios. +- **Consistency is king** — when in doubt, follow the established pattern. + +When these instructions don't cover a situation, apply these values to make the call. + +## Three Levels of Authority + +Every rule below is one of three kinds — know which, because they carry different weight: + +- **Framework contract** — enforced by Arc/Chronicle source, analyzers, or runtime. Violating it breaks the build or behaves wrongly. (e.g. `[Command]` needs a public instance `Handle()`; model-bound queries are static methods on `[ReadModel]`; nullable event properties raise a Chronicle analyzer warning.) +- **Cratis Application convention** — the house default for maintainability and consistent generated code. The framework does **not** enforce it, but follow it for consistency. (e.g. the slice folder shape, one backend file per small slice, declaration order.) +- **Product policy** — belongs in a downstream app's own `.cratis/ai/`, not this generic corpus. (e.g. specific roles, locales, design systems.) + +Where a rule is convention rather than contract, this file says so. Do not claim "the framework requires this" for a convention. + +## Project-Specific Instructions + +This corpus is the shared, generic instruction set common to every Cratis +repository. Individual projects need extra context that does not belong here, +such as product composition, approved environment names, directions for +obtaining credentials, and other local conventions ("Product policy" above). + +- Read repository-owned documentation as the canonical project-specific context when it + exists. +- Read repository-owned documentation only as the documented legacy fallback when + repository-owned documentation does not exist; never merge both contexts. +- Project context may explain which approved secret mechanism or local setup to + use, but it must never contain credential values, tokens, keys, passwords, or + other secrets. +- Project-specific guidance wins when it deliberately narrows shared behavior, + but it may not weaken organization security, authorization, or required + quality gates. + +## Collaboration Default + +Default to agentic behavior: inspect local rules, skills, code, tests, and generated patterns; make conservative assumptions supported by that context; implement and verify end to end when feasible. Don't interrupt with questions the repository can answer. Ask when the answer can't be found locally, when reasonable product/domain choices differ meaningfully, when a change is risky, or when the user asked for checkpoints. + +## Destructive operations + +Before a destructive or bulk external mutation, show the exact targets and +actions, explain how to recover, and obtain explicit user authorization. Re-read +the target state immediately before acting and stop if it changed. Git history +rewrites remain prohibited unless the user explicitly requests one. + +## New Repository Strategy Intake + +When a repository is created in the Cratis organization, prepare one transient, +no-effect Strategy intake proposal. Do not create, comment on, assign, mention, +link, or otherwise mutate a GitHub issue unless a current repository profile and +the exact operation are separately accepted. Tool access and a request to create +the repository do not supply that issue-effect authority. + +The proposal should include only the bounded facts needed for Strategy triage: + +- repository name, URL, visibility, and creation state; +- purpose, intended users, lifecycle, and whether it is canonical, generated, + experimental, operational, or scheduled for retirement; +- accountable owner or explicit vacancy and cross-repository boundaries; +- upstream/downstream dependencies and current owning records; +- release, distribution, credential, security, privacy, compliance, and data + expectations; and +- requested Strategy identity, portfolio, metadata, ownership, and local AI + context review. + +First decide whether no record, an existing Strategy record, a bounded update +proposal, a new proposal, or a sensitive human route is appropriate. Treat the +result as Strategy intake, not strategic approval. Do not invent Strategy +metadata or copy private Strategy content into a public repository. Repository +creation does not require an issue URL; unresolved Strategy reconciliation is an +explicit next action for the authorized human/owning process. + +## Shared AI Distribution + +Do not copy or synchronize shared `.cratis/ai`, `.agents`, `.claude`, `.github`, or +`.pi` trees from one Cratis repository to another. A consuming repository must +never become an accidental source that republishes its local AI corpus. + +Shared Cratis capabilities are authored and approved in `Cratis/AI`, generated +into `Cratis/AI.Distribution`, and installed only from an immutable reviewed +version after its release gates pass. Keep existing repository-local AI files in +place while the replacement distribution remains under canary; do not restart +legacy all-to-all propagation and do not delete legacy adapters before reviewed +retirement evidence exists. + +Shared public product and `engineering-*` packages contain only public-safe +Cratis behavior. The `engineering-` prefix identifies the maintainer audience; +it does not imply confidential package contents or a private registry. + +The consuming repository owns its project facts, confidential behavior, local +skills, and minimal host bootstraps. Use repository-owned documentation as canonical +project context when that migration is active, `.agents/skills/` for private or +repository-specific local workflows, and repository-owned documentation only as the +documented legacy context fallback. Never merge, overwrite, or remove these +local files as a side effect of installing, updating, rolling back, or +uninstalling shared AI capabilities. + +Keep confidential and repository-specific behavior local. Generalize and remove +private facts before proposing a reusable improvement to `Cratis/AI`; never +reverse-sync a private repository's AI tree or generated adapters. + +Update shared AI by changing a version pin through the approved organization or +host mechanism.

Cross-cutting concerns (shared concepts in `Common/`, shared components, identity) live at the top level. Namespace mirrors the path under `` (`...`, dropping any level that isn't present).

Static query methods are descriptive reads (`AllAuthors`, `AuthorById`, `AuthorsByName`). + +## Rules + +Tagged **[contract]** (framework-enforced) or **[convention]** (house default). Mechanics and examples live in `vertical-slices.md`. + +1. **[contract] Model-bound — no controllers.** Commands are `[Command]` records with a public instance `Handle()` (Arc analyzers enforce this); queries are `static` methods on `[ReadModel]` records; projections/constraints/authorization use attributes. Arc generates the HTTP surface. Drop to fluent (`IProjectionFor`, `IConstraint`) only when model-bound can't express the rule. +2. **[contract] Command validation & data flow.** Put command rejection in `CommandValidator`, global value invariants in `ConceptValidator`, and fetched/computed handler data in **`Provide()`** (runs after validation/authorization; may short-circuit with `ValidationResult.Error` / `Result`). Keep `Handle()` focused on event construction. For a state-dependent rule that must hold **under concurrency**, inject the read model into `Handle()` and return a typed error via `Result`. **Throwing from `Provide()`/`Handle()` is an exception (HTTP 500), not a validation rejection** — throw only for genuinely exceptional conditions, never for normal business rejection. +3. **[contract] Event-source id resolution order:** `ICanProvideEventSourceId` → an `EventSourceId`/`EventSourceId`-derived value → `[Key]` → else Arc/Chronicle generates one. A value actually used as a Chronicle stream identity derives from `EventSourceId` with the underlying `IComparable` primitive — never `ConceptAs` for that stream identity. `NotSet`, `New()`, and primitive→derived-id operators are optional domain/API conveniences, not Chronicle requirements; typed empty/zero values are real specified stream IDs, not `EventSourceId.Unspecified`. +4. **[contract] Events never carry the event-source id** — it is implicit in the event context. +5. **[contract] `[Key]` / `[Subject]` are distinct.** `[Key]` is for event-source/read-model/projection key resolution; `[Subject]` is compliance identity only. Don't put either on an `EventSourceId` value (it already is both); use them only for non-`EventSourceId` values. +6. **[contract] Avoid nullable event properties** — Chronicle's analyzer warns on them. Model optional facts as a separate event; resolve nullable command inputs to a non-null sentinel before constructing the event. +7. **[contract] `[EventType]` takes no arguments for new events** — the type name is the identifier. Use `generation:`/id only when evolving an existing contract; schema changes get a new generation + an `EventTypeMigration` (never edit stored-event semantics silently). An enum that only gains a member, or has one renamed, is the exception — Chronicle accepts that in place; a *removed* or *renumbered* member still needs a generation, plus a value map saying what the old values became. +8. **[convention] Every `[EventType]` has an XML ``** — a Cratis C# documentation convention (not a Chronicle rule); events live in the log forever, so record why they exist. +9. **[convention] `[ReadModel]` properties carry no default values** except semantically meaningful enum initial states and `[SetValue]`-driven `bool` flags. False defaults hide missing projection wiring. +10. **[contract] AutoMap is on by default — never call `.AutoMap()`.** Match property names so AutoMap wires them; diverge with `[SetFrom]` / fluent `.Set().To()` only for genuine name differences. Re-enable `.AutoMap()` only inside a scope where it was disabled with `.NoAutoMap()`. +11. **[contract] Projections consume events and event context — never other read models.** Default to model-bound attributes; use fluent `IProjectionFor` for joins/nested/context/transforms; use a reducer when the model is "current state + event → next state" (a valid style, not a failure mode). +12. **[contract] Model-bound query custom paths use `[Path("...")]`** (`PathAttribute`), not ASP.NET `[Route]`. Reserve `[Route]` for controller-based endpoints (which this convention avoids). +13. **[convention] Cross-slice access is read-only through Chronicle** — inject another slice's read model or reference its events; never instantiate or DI another slice's command/handler/service. +14. **[contract] Never inject `IEventLog` into `Handle()`** — express appends through return types (`IEnumerable` with `EventForEventSourceId` wrappers for cross-stream). In application reactors, return side-effect events or use `ICommandPipeline`; don't reach for `IEventLog` directly. +15. **[contract] Never edit a generated file** — proxies carry a `// @generated by Cratis` header. Fix the C# source and rebuild. +16. **[convention] Use the Cratis dialog wrappers** — never import `Dialog` from `primereact/dialog`; use `CommandDialog` / `Dialog` from `@cratis/components`. The default frontend stack is Cratis Components on PrimeReact theming/tokens/`pt` — **not** Tailwind (Tailwind is one supported unstyled path, not the generic default). +17. **[convention] One slice is one unit** — creating/renaming/moving/deleting a slice means doing the same to every artifact (the `.cs`, every `when_*/`, every `.tsx`, the composition import/JSX, the route). + +## Implementation Workflow + +- **Phase 0 — Model the request.** Confirm Module/Feature, Slice name, slice type, domain rules. For new behavior or unclear event vocabulary, run the **event-modeling** skill before writing code. +- **Phase 1 — Backend.** Implement a coherent slice change. **Gate:** incrementally build the affected Debug project to regenerate proxies and compile spec code; add Release verification when required for cross-cutting or merge/release gates (see the proxy-generation note below). +- **Phase 2 — Specs.** Mandatory for every slice type, in-process scenario family first: `CommandScenario` (commands), `EventScenario` (constraints/append), `ReadModelScenario` (projections/reducers), `ReactorScenario` (reactors). Reserve out-of-process integration specs for host/infra/transport boundaries. **Gate:** tests pass. +- **Phase 3 — Frontend.** Proxies now exist. Build React components from generated proxies, register in the composition page, wire routing. **Gate:** lint, conditional test, and build all clean. + +**Backend before frontend, always** — the frontend depends on proxies that only exist after a successful Debug build. After a coherent set of changes, incrementally build/compile the affected project and run targeted regression checks before proceeding; do not build after every file. + +**Proxy generation runs on Debug, not Release.** `dotnet build -c Debug` is the canonical trigger for regenerating TypeScript proxies — it carries the fullest, most reliably-emitted PDB debug information the proxy generator relies on to place generated files. Generate proxies with a Debug build first; when you (or an agent) subsequently build Release purely to verify the app compiles in that configuration, skip proxy regeneration so the second build can't re-run the generator against a different compilation and touch already-correct generated files: `dotnet build -c Release -p:CratisProxiesOutputPath=`. The empty override clears the output path property the generator's MSBuild target is conditioned on, so the target no-ops for that invocation — no generated file is read or written. + +## Quality Gates + +| Phase | Command (app-pinned) | Pass criteria | +| --- | --- | --- | +| Backend | build (Debug) | zero errors, zero warnings — validates `#if DEBUG` spec code and regenerates proxies | +| Backend | build (Release) | zero errors, zero warnings — build-only check; pass `-p:CratisProxiesOutputPath=` to skip re-running proxy generation | +| Specs | test | zero failures | +| Frontend | lint | zero errors | +| Frontend | test | zero failures when frontend specs/behavior changed | +| Frontend | build | zero errors | + +Run affected-project incremental checks after a coherent change, then targeted regression tests for the changed behavior.

A reviewer reading a coherent series of small commits is better served than by one squashed blob, and the project does not require a linear history. +- **Landing a PR?** `gh pr merge --merge` (a real merge commit). **Not `--squash`, not `--rebase`.** The commits on the branch are the record of how the change was actually built; squashing throws that away permanently in exchange for a tidier `main`, which is not a trade this project makes. +- **Need someone else's changes?** `git merge`, never `git rebase`. +- **Need to move a commit to another branch?** `git cherry-pick` — it copies, leaving the original reachable. +- **Working alongside another agent or session?** Use `git worktree add` so each has its own checkout and branch.

If a commit has gone missing, `git reflog` is the recovery tool: find the SHA, `git tag` it immediately so `gc` cannot take it, then `git cherry-pick` it back. + +## Logical Grouping + +Every commit must be a **single logical unit of work**. Group related changes together; separate unrelated changes into distinct commits. + +### What belongs in one commit + +- A bug fix and the spec that proves it. +- A new file and the changes to existing files needed to integrate it (imports, registrations, wiring). +- A refactor that moves or renames code — only the mechanical transformation, nothing else. +- An interface change together with all implementation updates required to compile. + +### What does NOT belong in one commit + +- A bug fix mixed with an unrelated feature. +- Source code changes mixed with unrelated spec additions for a different area. +- Formatting or style cleanups bundled with behavioral changes. +- Multiple independent fixes or features squashed into a single commit. + +### Deciding where to split + +Ask: "If I needed to revert this commit, would I lose exactly one coherent change?" If reverting would undo two unrelated things, it should be two commits. + +Common split points: + +1. **Infrastructure / plumbing first** — interface additions, new types, or schema changes that later commits build on. +2. **Core logic second** — the behavioral change that uses the new infrastructure. +3. **Specs / tests third** — the specs that prove the behavioral change works. Specs may also be combined with the core logic commit when they are tightly coupled (e.g., a TDD red-green cycle or a bug fix with its regression test). +4. **Integration or wiring last** — connecting the new behavior to the rest of the system (DI registration, routing, UI hookup). + +When a task produces both source fixes and new integration specs, prefer separate commits for the source changes and the specs — unless the specs are inseparable from the fix (e.g., a single bug fix + its regression test). + +## Commit Messages + +### Format + +```text + + + +``` + +- **Subject line**: imperative mood, present tense.

If you cannot describe the change in 72 characters, the commit is probably too large — split it. +- **Body**: separated from the subject by a blank line.

The "if this then that". +- **Observer** — Chronicle's umbrella for anything consuming an event sequence (projection, reducer, reactor); carries subscription / replay / **quarantine** state. +- **Sink** — where a read model is persisted (MongoDB, EF Core). +- **AutoMap** — Chronicle's on-by-default mapping of matching event→read-model property names; **never call `.AutoMap()`**. +- **Query** — a `static` method on a `[ReadModel]`; returns derived state, **snapshot** (one-shot) or **observable** (live). + +## Write side + +- **Command** — a `[Command]` record expressing an imperative **intent**; its public `Handle()` produces event(s) (or a response). +- **Provide()** — the command method that fetches/computes data after validation/authorization and before `Handle()`; may short-circuit with a `ValidationResult`. +- **Causation chain** — the ordered links saying how an append came about (root process → command → …), each carrying properties. A command records its **name and its property values** there, so an event says what the command was asked to do; the chain lives in the event log and is as permanent as the events. +- **Constraint** — `IConstraint`; an **append-time** invariant (uniqueness / concurrency) enforced at the event-store level. +- **DCB (Dynamic Consistency Boundary)** — enforcing a state-dependent rule **under concurrency** by injecting the read model into `Handle()` and returning `Result`. +- **Consistency boundary** — the scope within which an invariant holds atomically (an event source, or the read model a DCB rule inspects). +- **EventForEventSourceId** — self-describing wrapper to append an event to a **specific** (cross-stream) event source, from a command `Handle()` or from a reactor handler (reactor support has shipped since Chronicle 15.35).

Withholds only; it does not encrypt or enroll the value in erasure the way Chronicle's `[PII]` does. +- **`[OnceOnly]`** — marks a reactor handler (or the whole reactor class) as non-replayable: Chronicle skips it for every event arriving as part of a **replay** — observer rewind, redaction, revision. Replay-exclusion only, not exactly-once and not per-event-source deduplication; recovering a failed partition re-delivers the event as an ordinary observation and the handler runs again.

It also keeps diffs clean and makes imports explicit. + +- Every interface, type alias, and enum lives in **its own file**, named after the type (e.g. `SliceType.ts`). +- **Never create** `types.ts`, `models.ts`, `interfaces.ts` grab-bag files — they become dumping grounds that grow without limit. +- Exception: component props interfaces (`*Props`) may live alongside their component `.tsx` file since they are tightly coupled to that component. +- Aggregate exports through the folder's `index.ts`. + +## Type Safety + +`any` disables the compiler — the one tool that catches bugs for free. Every `any` is a hole in the safety net. Use `unknown` and narrow with type guards instead. + +- Never use `any` — use `unknown`, `Record`, or proper generic constraints. +- Prefer `value as unknown as TargetType` over `value as any`. +- Use `unknown` as default generic parameter instead of `any`. +- React synthetic events (`React.MouseEvent`) and DOM events (`MouseEvent`) are different types — don't mix them. +- **`int64`/`uint64` Chronicle fields generate as `bigint`** in the TypeScript proxies (not `number`, which silently truncated past `Number.MAX_SAFE_INTEGER`). Sequence numbers, large counters, and 64-bit ids surface as `bigint` — use `bigint` arithmetic, never `Number()`. + +## User-facing strings (localization) + +How user-visible text is handled is **product policy, not a Cratis framework rule** (see [general.md](./general.md) — locales belong in a downstream app's own `.cratis/ai/`). Cratis itself has no mandatory i18n layer or `Strings` alias. + +- If the app has a localization convention (e.g. a translation object behind a `strings`/`Strings` import, or any i18n library), follow it consistently and keep raw string literals to constant, non-user-facing values (CSS class names, `key` props, internal identifiers). +- If the app ships literal text, literal labels in JSX are fine. + +Either way, the Cratis-generic rule is only that strings are handled consistently within the app — not a specific file layout or import alias. + +## Arc Frontend Patterns + +Arc's proxy generator bridges C# and TypeScript automatically — every `[Command]` and `[ReadModel]` becomes a TypeScript class with `.use()` hooks, `.execute()` methods, and change tracking. This is the foundation of full-stack type safety: change a C# record and the TypeScript proxy updates on the next `dotnet build`. + +### Commands + +Auto-generated from C# `[Command]` records. The `.use()` hook returns a tuple: the command instance (with change tracking) and a setter for property values. + +```tsx +const [command, setValues] = OpenAccount.use({ name: '', owner: '' }); +await command.execute(); // Sends command to backend, returns CommandResult +await command.validate(); // Pre-flight validation only, no side effects +command.hasChanges; // True when any property differs from initial values +command.revertChanges(); // Reset all properties to initial values +``` + +### Queries + +Auto-generated from C# `[ReadModel]` static query methods. Observable queries (returning `ISubject` on the backend) auto-subscribe via WebSocket — the component re-renders when data changes on the server. + +```tsx +const [result, perform] = AllProjects.use(); +// result.data — the query result +// result.isPerforming — true while loading +// result.hasData — true when data has arrived +// result.isSuccess — true when query completed without errors +``` + +Paginated queries: +```tsx +const [result, , setPage] = AllProjects.useWithPaging(10); +``` + +### CommandScope + +Wraps multiple command-using components, aggregating their `hasChanges` state and enabling bulk `execute()` and `revertChanges()`. Useful for forms that span multiple components. + +### CommandForm + +Declarative form component with built-in field types, validation timing (`validateOn: blur|change|both`), and automatic server-side validation feedback. + +## Language — American English Only + +All identifiers, comments, JSDoc, and string literals must use **American English** spelling (initialize, serialize, behavior, color, organization, center, modeling, dialog, license, judgment, gray). See [general.md](./general.md) for the full guidance. + +## Variables and Naming + +- Prefer `const` over `let` over `var` when declaring variables. +- Never use shortened or abbreviated names for variables, parameters, or properties. + - Use full descriptive names: `deltaX` not `dx`, `index` not `idx`, `event` not `e`, `previous` not `prev`, `direction` not `dir`, `position` not `pos`, `contextMenu` not `ctx`/`ctxMenu`. + - The only acceptable short names are well-established domain terms (e.g. `id`, `url`, `min`, `max`). + +## Imports and Compilation + +- Never leave unused import statements in the code. +- Always ensure that the code compiles without warnings — use `yarn compile` to verify (successful runs produce no output). +- Review each file for lint compliance before finalizing. +- Never use placeholder or temporary types — use proper types from the start. +- **Never modify any file inside `node_modules/` or any build cache (e.g. `.vite/deps/`).** These are managed by the package manager and will be overwritten on the next install. If something appears broken in a library, look harder at the application code — especially when other usages of the same library work fine. Fixes belong in application code or upstream in the library's own repo. + +## Folder Structure + +- Do not prefix a file, component, type, or symbol with the name of its containing folder or the concept it belongs to. Instead, use folder structure to provide that context. +- Favor functional folder structure over technical folder structure. + - Group files by the feature or concept they belong to, not by their technical role. + - Avoid folders like `components/`, `hooks/`, `utils/`, `types/` at the feature level. + +## Advanced Type Safety + +Additional patterns for common tricky scenarios: + +**Storybook:** +- Use `React.ComponentType>` for components with no props. +- Always use `as unknown as` when converting component imports to avoid type mismatch errors. +- Properly type story args — never use `any`. + +**External libraries with strict generic constraints:** +- Import necessary types (e.g. `Command` from `@cratis/arc/commands`) rather than asserting to `any`. +- Use type assertions through `unknown`: `props.command as unknown as Constructor>`. +- Extract tuple results explicitly rather than destructuring when type assertions are needed. +- Use proper library types when available; use specific property types (e.g. `{ canvas?: HTMLCanvasElement }`) over `any`. + +**Dynamic and generic types:** +- Add type guards for unknown function parameters: `if (typeof accessor !== 'function') return ''`. +- Type parameters with fallbacks: `function(accessor: ((obj: T) => unknown) | unknown)`. +- Cast arrays from `unknown` explicitly: `((obj as Record).items || []) as string[]`. +- Use `String(value)` for string conversions in generic contexts. +- Use explicit Date parameter types: `new Date(value as string | number | Date)`. diff --git a/.cratis/ai/rules/verification-discipline.md b/.cratis/ai/rules/verification-discipline.md new file mode 100644 index 0000000..b7b366b --- /dev/null +++ b/.cratis/ai/rules/verification-discipline.md @@ -0,0 +1,22 @@ +--- +applyTo: "**/*" +paths: + - "**/*" +--- + + +# Verification Discipline + +Verification answers whether changed behavior works.

A change that + silently contradicts an accepted record is a defect even when the code is + correct. +3. **Apply the significance test before writing anything.** Write a record only + when at least one of these holds: someone will otherwise re-litigate the + choice; it binds paths beyond the one you are changing; reversing it would + cost real migration or rework; or it rejects an option a reasonable reader + would reach for. If none holds, say so and make the change without a record. +4. **Pass the completeness gate, or open with `status: returned`.** A proposed + record states the options considered *including the one not taken and why*, + the default that applies if the question is never answered and what that + default costs, the timeline the decision has to hold to, and what is in scope + and out. A record missing any of the four is returned to its proposer for + revision — `returned` is not a rejection. +5. **Write the verification criterion before acceptance, not after.** State the + observable signal that will say the decision was actually carried out, as + `Done when` and `Verify by`. A decision whose success cannot be observed + cannot reach `stage: verified`. +6. **Open the record as `status: proposed`, `stage: none`, and regenerate the + index.** A record the index does not list is a record the consult step in + step 1 will never find. +7. **Accept by recording a resolved actor and a date.** Set `status: accepted`, + `decided` to the date, and `decider` to a named person — never a role, a + team, or a tool. Acceptance is a human verdict: draft it, do not grant it. +8. **Spawn the build work carrying the criterion verbatim.** The `Done when` and + `Verify by` text written in step 5 travels onto the work item unchanged, so + the thing that gets built is the thing that was decided. +9. **Move `stage` only on the evidence the next stage requires.** `none` → + `implemented` when the change exists in the tree; `implemented` → `verified` + only on a signal observed this time. Accepted is not implemented, and + implemented is not verified. +10. **Supersede rather than rewrite.** Never edit an accepted record's decision + text in place — that text is what people relied on. Correct a typo or add + context under a dated banner that says what changed and why.

A swallowed conflict reported as a successful release + +*release-action #178.* + +**Boundary.** Publishing a version — the most public effect there is. + +**What happened.** A concurrent publish made the registry return HTTP 422. The +action caught it and continued, and the run reported the release as successful. + +**Why it was expensive.** The one artifact that recorded the truth was an +exception nobody saw. Everything downstream — release notes, subscriber pins, +the assumption that the version existed — was built on a success that had not +happened. Nothing later in the pipeline re-checked the registry, because a +successful publish is normally proof enough. + +**What the contract required.** A 422 on publish is an outcome that must be +classified, not caught. Either the version already exists and is byte-identical +(report it as already-published, explicitly), or it does not and the publish +failed. "Caught an exception, carried on" is neither. + +## 2. A generator that degrades silently + +*Arc #2571, #2564, #2527 — the proxy generator.* + +**Boundary.** Generating TypeScript proxies from C# sources. The output is what +the whole frontend compiles against. + +**What happened.** The generator produced fewer proxies than its inputs implied +and still exited zero. + +**Why it was expensive.** The symptom appears far from the cause: a missing +TypeScript type in a component, at a point where nobody is thinking about the +generator. The natural first hypothesis is that the frontend is wrong. + +**What the contract required.** A generator that consumed N inputs and emitted +fewer than N artifacts reports the delta and fails, or names the skipped inputs +and why. Reporting the count on success is what makes the shortfall visible at +all: "generated 41 of 41" and "generated 38 of 41" have to read differently. + +## 3. A renderer that quietly renders less + +*Stage #53.* + +**Boundary.** Rendering output that someone will look at and act on. + +**What happened.** A degraded rendering path produced partial output while +reporting success. + +**Why it was expensive.** Partial output looks like output. There is no error to +search for and no count to compare, so the difference between correct and +degraded is invisible at exactly the boundary that produced it. + +**What the contract required.** A renderer that could not render something says +so in its result — a degraded-mode signal the caller has to handle, not a log +line at the end of a stream nobody reads. + +## 4. A container that stays `Running` after startup threw + +*Chronicle #3682.* + +**Boundary.** Process and container lifecycle — the state an orchestrator reads +to decide whether to send traffic. + +**What happened.** Startup threw, and the container remained in `Running`. + +**Why it was expensive.** The orchestrator believed the reported state and kept +routing to a host that had never finished starting. The failure surfaces as +inexplicable behavior in callers rather than as a failed start. + +**What the contract required.** Process state follows the work. If startup +failed, the process exits non-zero or reports unhealthy. A liveness state that +survives a failed start is not a degraded signal, it is a false one. + +## 5. A constraint that only one implementation enforces + +*Chronicle #3744 — unique constraints on the SQL and in-memory providers.* + +**Boundary.** Persistence, and the invariant the store is supposed to guarantee. + +**What happened.** Unique constraints were not enforced on the SQL and in-memory +storage providers, while the primary provider enforced them. + +**Why it was expensive.** This is the worst variant, because it does not fail — +it makes specifications pass vacuously. Every test written against the +in-memory provider proved that duplicate writes were accepted, and read as +proof that the constraint worked. The gap only appears in the one environment +nobody tests against by default. + +**What the contract required.** An alternate implementation of an interface +matches the primary one's *semantics*, not just its signature. Where it cannot, +it throws rather than silently accepting. The specification that proves the +constraint runs against every implementation. + +## 6. A fan-out that succeeded 29 times out of 36 and said "done" + +*The retired corpus propagation.* + +**Boundary.** Propagating content into other repositories — an effect in 36 +places at once. + +**What happened.** Per-target results were aggregated into a single overall +success. Seven repositories did not receive the change, and the aggregate said +nothing about it. + +**Why it was expensive.** Nobody knew which seven. Recovering meant re-deriving +the target list and comparing every repository by hand, long after the run's +own record of what happened had been lost to log rotation. + +**What the contract required.** Attempted, succeeded, and failed are three +separate numbers, all three in the returned result and the summary line. A +fan-out that cannot name its failures has not reported its outcome. "29 of 36" +is not a success with a footnote; on an effect boundary it is a failure. + +## What the six have in common + +- The failing code **caught something and continued**, or **mapped an + unmodelled outcome onto success**. +- The success signal was **produced by the layer that failed**, so no later + check re-derived it. +- The cost was paid **downstream, by someone who could not see the boundary**. +- In the two worst cases (2 and 5) the defect made verification itself + meaningless: a green generator run and a green specification suite that were + both measuring nothing. diff
