New ui-api blueprint for authoring SML rule drafts from the UI, with submission routed through a pluggable backend so each deployment picks where drafts go for review. Endpoints (all gated by a new CAN_EDIT_RULE_DRAFTS ability, granted to super_user): get-source, validate, vocabulary, submit, pending, and parse-into-builder. Validate and submit splice the draft into the engine's loaded sources and re-run the same AST validation the engine uses; submit re-validates server-side before touching any backend. Backends implement the RuleSubmissionBackend Protocol and are selected by OSPREY_RULES_SUBMISSION_BACKEND: - null (default): fails fast with 503 so an unconfigured install never writes anything - github: opens a PR via the REST API; supports GitHub Enterprise - local: writes into a mounted rules directory Contract and safety details: - SubmissionResult/PendingDraft.to_json spread extras first so a backend-specific extra can't shadow the canonical title/url/ main_sml_updated fields the UI depends on - Forge transport failures (connection refused, timeout) become the structured 502 the UI renders, not an unhandled 500, via a shared _rule_drafts_git_common.request() helper that also holds the branch-name and main.sml Require helpers - main.sml is rejected as a draft path: wholesale-replacing the engine entry point is not a draft; wiring a rule in is the controlled wire_into_main append Adopter docs for the env vars are in docs/user/manage.md. Follow-ups add the rule-editor UI, a GitLab backend, and a Tangled (ATProto) backend.

Feedback on #402 was to drop the github/gitlab/etc submission backends and instead keep drafts in Osprey itself. This does that: rule drafts now live in a rule_drafts Postgres table that the people who operate Osprey can reference, edit, and deploy from, with no external code host. - Add the RuleDraft model (one row per rule path, upserted on save) and register it so the table is created. - Rework the view around the table: create/list/get plus a deploy endpoint that re-validates, writes the SML into OSPREY_RULES_LOCAL_PATH, and optionally wires a Require line into main.sml. Keep the backend-agnostic authoring endpoints (source, validate, vocabulary, parse-into-builder). - Remove the five _rule_drafts_* backend modules and the OSPREY_RULES_SUBMISSION_BACKEND config surface. - Rewrite the tests for the table workflow; update docs and CHANGELOG. A DB-backed SourcesProvider that loads deployed drafts straight from the table (removing the filesystem hand-off) is noted as future direction.

SML rule names are global identifiers, so two drafts sharing a name would collide once both deploy. Server-side validation only sees deployed rules, not other rows in the rule_drafts table, so it can't catch the draft-vs-draft case. Add RuleDraft.other_with_rule_name() and have create_draft return 409 when a different path already uses the name (re-saving the same path is still an in-place update, not a conflict).

Feedback from CodeRabbit and @ThisIsMissEm on the rule-drafts backend: - Don't leak raw exception text to clients; log server-side and return a generic message when sources can't be assembled (both /validate and the create/deploy re-validation). - Share one `_validate_draft_source` helper between /validate and the server-side re-validation so the two can't drift. - Catch the specific RuntimeError/AttributeError from `span.ast_node` instead of a bare `except: pass` when extracting the identifier. - Deploy: verify main.sml exists before writing the rule file, so a missing main.sml no longer leaves the file written while the request 409s. - Deploy: report `path_on_disk` relative to the rules directory rather than leaking the absolute server path. - Make the path upsert atomic with INSERT ... ON CONFLICT DO UPDATE so two concurrent saves of the same path can't race the unique constraint. - Reject absolute paths in `_validate_path`; drop the stray `.` from the path character class; use `expunge_all()`; note that Osprey has no users table (identity is an email + ACLs). - Tests: clear the rule_drafts table between tests (the DB is session-scoped) and assert the deploy 409 leaves no file behind.

@ThisIsMissEm noted the /rule-drafts/source endpoint reads any deployed rule's source, not a draft's. Reword the 404 to "No rule found at ..." (it doesn't consult the drafts table, so "draft" would mislead) and add a docstring saying it's for editing an existing on-disk rule, while a draft's own SML comes from GET /rule-drafts/<id>.

Feedback from @chimosky on the rule-drafts view: - Read OSPREY_RULES_LOCAL_PATH via CONFIG.get_str() instead of os.environ, for consistency with how the rest of the UI API reads configuration. The deploy tests set it directly on the bound config since CONFIG binds once at app setup. - Make the invalid-path error human-readable ("letters, numbers, underscores, slashes, and hyphens") instead of echoing the raw character class. - Use `[]` as the default in _suggest_imports_from_errors rather than `or []`.

`ValidateCallKwargs.validate_call_node` asserted that a Call's callee was a `Name`, so `Foo.Bar(...)` raised an AssertionError. The grammar allows one level of attribute access and the parser accepts an attribute callee, but no validator implements one -- the assert was standing in for a diagnostic that was never written. That was survivable while the only SML the validators saw came from the rules directory, where a crash is a startup failure an operator reads in a traceback. It stops being survivable now that the same validators run over user-submitted SML from the rule-draft editor: an uncaught assert there is a 500, not an inline error the author can act on. `ValidateCallKwargs` now reports "calling attributes isn't supported yet" against the callee's span, matching how `ValidateStaticTypes` already refuses the non-call form. `ValidateCallRValue` had a second copy of the same assert, placed after `validate_call_node` had already returned early on exactly this input; it is dropped rather than converted, because reporting the unsupported callee is `ValidateCallKwargs`' job and doing it twice would double the error.

`views/tests/test_queries.py::test_get_queries` asserted `len(res.json) == 21` with a note that "the number of queries may vary based on other tests that have run". It was not counting anything it created -- 21 was a census of whatever the whole suite had left in the `queries` table, so the test passed only when `lib/storage/tests` had run first in the same session and failed for any subset of the suite. It now creates a known number of records and asserts on the delta, which holds however the suite is sliced. The residue itself is also worth removing, since it is what made the count non-deterministic in the first place: the test database is session-scoped, so rows outlive the test that made them. `lib/storage/tests/test_queries.py` gets an autouse fixture that empties `queries` and `saved_queries` before each test. Both are prerequisites for running these modules on their own, which the rest of this branch does often.

In `@osprey_worker/src/osprey/worker/lib/storage/rules.py`:
- Line 1: Remove the file-wide `reportAssignmentType=false` directive and
restore assignment type checking in `rules.py`. Fix the underlying assignment
errors, or replace only unavoidable cases with narrowly scoped, documented `#
type: ignore[assignment]` suppressions at the affected lines.
In `@osprey_worker/src/osprey/worker/ui_api/osprey/lib/rule_builder.py`:
- Line 11: Replace the newly introduced Any annotations in the Builder parser
with the shared AST base type or appropriately narrow unions for AST nodes and
arguments. Update the affected annotations and imports so mypy can validate
supported node access without adding type: ignore directives.
- Line 121: Update the source.ast_root exception handler to return a stable
parse-failure reason without including str(exc) or other exception details in
the API response, and log the caught exception server-side using the module’s
existing logging approach.
- Line 193: Update the WhenRules validation around rules_any_arg and the
corresponding then argument so the call is accepted only when both arguments are
present and each has the supported AstList shape; return unsupported for missing
or non-list arguments instead of emitting blank defaults. Add regression
coverage for malformed and missing arguments.
In `@osprey_worker/src/osprey/worker/ui_api/osprey/lib/rules.py`:
- Around line 74-83: Update both broad exception handlers in the UDF-building
flow to log the caught exception through the existing logger before continuing
or falling back to an empty items collection. Keep the current control flow and
fallback behavior unchanged while including enough context to identify the
affected UDF and failed operation.
In `@osprey_worker/src/osprey/worker/ui_api/osprey/validators/rules.py`:
- Around line 36-37: Update the request validation method containing
flask_request.get_json so it rejects valid JSON bodies that are not objects with
the existing 400 validation behavior, and merge the JSON body before
flask_request.view_args so route parameters override duplicate body keys.
Preserve empty-body handling and the existing parse_obj validation flow for
object bodies.

`views/rule_drafts.py` had grown to 749 lines holding four unrelated jobs: HTTP
routing, request validation, SML parsing and rule-building, and the filesystem
hand-off that deploys a rule. `views/rules.py` held a fifth, the read-only
catalog. Nothing could be tested without a Flask request context, and the draft
and catalog endpoints had drifted into two spellings of the same concepts.
The work is now split by what each piece is responsible for rather than by which
endpoint happened to need it first:
views/rules/ routing only -- catalog, drafts, vocabulary
lib/rule_*.py the logic, callable without a request context
schemas/ the pydantic models crossing the API boundary
validators/ request-shape validation
Deploy failures illustrate the seam: `lib/rule_deployment` raises `DeployError`
subclasses that each carry the status a view should map them to, so the choice of
status lives with the failure that motivates it and the module stays free of HTTP
concerns.
The storage layer follows: the table is `rules`, not `rule_drafts`, because a row
is a rule at some point in its lifecycle rather than a permanently separate kind
of thing -- deploying marks the row, and editing a deployed rule returns it to
draft. `lib/storage/tests/test_rules.py` covers the uniqueness constraint and
that round trip.
`views/_engine_ast_utils.py` becomes `lib/ast_utils.py` and gets much smaller by
not reimplementing things the engine already does: rendering an expression is
`ast.printer.print_ast`, traversal is `ast_utils.filter_nodes`. `features.py`
follows it. One behaviour change falls out: `get_func_identifier` now returns
None for an attribute callee rather than the attribute's name, because callers
compare the result against bare names ('Rule', 'WhenRules') and reporting
`Foo.Bar(...)` as 'Bar' would let a namespaced call impersonate a top-level one.
The preceding commit is what makes that reachable only through the rule builder,
which parses raw unvalidated editor SML.
Rule access moves off `CAN_EDIT_RULE_DRAFTS` and `CAN_VIEW_DOCS` onto a
read/write/publish ladder -- `CAN_VIEW_RULES`, `CAN_EDIT_RULES`,
`CAN_DEPLOY_RULES`. Editing and deploying are separate grants because the blast
radius differs: a draft is reversible and private to the UI, a deploy is neither.
BREAKING: `GET /rules` previously required `CAN_VIEW_DOCS`. ACLs granting only
that ability lose the Rules Registry page until they also grant `CAN_VIEW_RULES`.

The UI needs a way to detect whether rules can be authored and/or deployed. This introduces three new configuration properties: - `can_deploy_rules`: user permission check for `CAN_DEPLOY_RULES` - `can_edit_rules`: user permission check for `CAN_EDIT_RULES` - `rule_deployment_enabled`: whether or not rule deployment can take place The `rule_deployment_enabled` reuses the existing logic that gates deployments, via `is_deploy_available`. A user may have the permission to deploy, but deployments may be disabled. No UI change yet: nothing renders a deploy control today. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Mirrors the formatters the repo already runs -- ruff for Python, prettier for osprey_ui -- so an editor without those plugins still produces conforming files rather than a diff the formatter has to undo. It adds no new rules: every value here is read off pyproject.toml [tool.ruff] or osprey_ui/.prettierrc. Two entries are not derived from a formatter. `*.sml` is 2-space because that is how rules are written in this repo, including the ones the in-app rule editor generates, and no formatter covers SML. `*.md` keeps trailing whitespace, since two trailing spaces are a hard line break in Markdown.

Prompts new contributors to install the extensions that enforce what CI already checks -- ruff, prettier, eslint, editorconfig -- plus Python and Pylance. A recommendation only: VS Code offers them once and nothing here changes anyone's settings. `.vscode/settings.json` is deliberately not included; workspace settings are a personal choice and are commonly gitignored.

We already included .idea but I was having issues with vscode using jedi instead of pylance, where autocomplete and other code intellisense was breaking, this at least fixes it somewhat. (I do have a config file that would fix more fully)

@julietshen this is the line that was causing some strife earlier, in #402, once rebased against main, it ended up under 1.1.0 which was unreleased at the time, but git's merging does some weird things sometimes where it doesn't quite pick up on author's intent.

In case you're wondering why we have DraftSummary here, it's to reduce overfetching the drafts continuously from the client side, as previously it included all the other fields on a draft, which isn't necessary for just a list of drafts. (list vs get one tends to be minimal vs full)
docker-compose.test.yaml clears container_name, ports and volumes on the shared services so a test stack can coexist with a running dev stack -- its own header says so. That only holds if the two are separate compose *projects*, and run-tests.sh passed no -p, so compose derived the project name from the directory: the dev stack's. The overrides were therefore applied to the dev containers, recreating postgres with no host port and, worse, no volume, which silently destroyed the local development database and left osprey-ui-api unable to connect. Also adds run-tests-local.sh for running the suite on the host against an already-running stack. It uses the osprey_test database rather than osprey for the same class of reason: the session fixture drops the database it created, so pointing a local run at the dev database deletes it.

There is no authentication in the UI API: `set_dummy_claim` attaches whatever identity the request claims, defaulting to local-dev@localhost. Testing what a less-privileged user sees therefore meant editing that default in place, which breaks every authz test in the suite -- they all grant their abilities to local-dev@localhost, so the change lands as ~78 failures in tests that have nothing to do with auth. There are now two ways to be someone else without touching the source: OSPREY_DEV_USER_EMAIL changes the default for the process, so the stack can be booted as a particular user and the browser follows; X-Test-Email still changes it for one request, so a second role can be driven from curl alongside. Adds a RULE_AUTHOR role granting CAN_VIEW_RULES and CAN_EDIT_RULES but not CAN_DEPLOY_RULES. Without it no shipped definition can produce the user the split abilities exist for -- one who drafts rules but cannot deploy them -- so that path was unreachable outside the tests. dev_acl_assignments.json is gitignored: committing it would silently stop every developer being a super user, and its absence is what makes a fresh checkout work. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PPgvKLEB4FrubcAD7paJTP
Adds a `cid` column: the SHA-256 of a draft's SML, maintained by `upsert` so it cannot disagree with the source it addresses. No normalisation -- the question being asked is "is this the same text?", not "is this the same program", because the thing it will be compared against is a file on disk a human may have edited. Deploy writes `sml_source` verbatim, so `content_id(rule.sml_source)` is also the hash of the deployed file, which makes drift detectable without keeping a second copy of the text to diff against. The `rules` table is new and unreleased, and `metadata.create_all` adds missing tables but never missing columns, so adding this now costs one line where adding it later would need a hand-written migration in a repo with no migration story. Splits the wire shape in two while the column is being added, because the two changes explain each other. `GET /rules/drafts` now returns `DraftSummary`, which omits `source`: only the editor needs a draft's SML and it opens one draft at a time, so listing it shipped every rule's text on every request -- growing with the size of the table rather than with what the page renders. `cid` replaces it at 64 bytes, answering "is the copy I hold current?" without transferring the source. `RuleRecord` subclasses `DraftSummary` and adds `source`, `summary` and the remaining timestamps, so the detail shape is provably a superset of the list one.

Splitting CAN_EDIT_RULES from CAN_DEPLOY_RULES created a handoff with no channel: an author can write and save a draft but not ship it, and had nothing to say "this one is ready" with. The table showed `draft` for both work in progress and work waiting on a reviewer, which is exactly the distinction a queue needs. Adds a third RuleStatus, `deploy_requested`, and `POST /rules/drafts/<id>/ request-deploy` to set it. Gated on CAN_EDIT_RULES rather than CAN_DEPLOY_RULES: gating it on deploy would mean only people who can already ship a rule could ask for one to be shipped. Editing a requested draft returns it to `draft`, which falls out of `upsert` already setting status unconditionally -- the request was for particular text, and the text changed, so it should leave the reviewer's queue. Tested, because that is the property a reviewer relies on. Requesting a deployed rule is permitted and reads as a redeploy request; `deployed_at` stays set, so a first request and a redeploy request remain distinguishable. Worth allowing rather than refusing, because a rule whose file was edited or deleted on disk genuinely needs deploying again and the row is the only place to record that. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PPgvKLEB4FrubcAD7paJTP
`GET /rules/drafts/<id>/deploy-plan` answers what deploying would do, without doing it, so the confirmation dialog can state what is about to happen rather than describe it conditionally. It currently has to hedge -- "append Require(...) if not already present" -- because the client cannot know; the plan replaces that with the literal line, or with the fact that main.sml already requires the rule. Three state objects, one per thing that can go wrong, so every reason the deploy would fail is a named state rather than a separate list of reasons: source valid | invalid rule_file new | identical | differs main_sml would_append | already_required | missing | unparseable `unparseable` matters: without it a broken main.sml reads as `would_append` for a deploy that then 409s, and a plan that is confidently wrong about the failing case is worse than no plan. `identical` and `differs` come from comparing the stored `cid` against a hash of the file, which is what finally detects a rule edited or deleted on disk since it was deployed -- until now the row still said `deployed` and nothing disagreed. `deployable` and `wireable_into_main` are two independent booleans rather than one answer parameterised by a wiring flag. Reading main.sml once settles both, and they map onto the dialog's two controls: the checkbox is enabled by the second, the button by `deployable and (not checked or wireable_into_main)`. So toggling the checkbox re-renders instead of re-requesting. Gated on CAN_DEPLOY_RULES: the plan is only actionable to someone who can deploy, and it reports server-side state an author has no use for. It raises the same DeployErrors as the deploy itself for the conditions that make planning impossible, so a plan cannot succeed where the deploy would 503. Advisory only -- nothing locks the rules directory between planning and deploying, so `deploy_rule` re-runs every check and can still refuse.

Add regression tests for the database deletion guard.
Test all four combinations of created_by_this_run and database names with and without the _test suffix. This guard controls whether teardown can delete a database.

Contributor

@ThisIsMissEm, this is testable without running the fixture setup.
_is_disposable_database is a pure helper. A small unit test can import it and call it with PostgreSQL URL strings. It does not create or delete a database.
The test should cover these cases:
created_by_this_run=Trueand database name ending in_test→Truecreated_by_this_run=Trueand database name not ending in_test→Falsecreated_by_this_run=Falseand database name ending in_test→Falsecreated_by_this_run=Falseand database name not ending in_test→False
This protects the condition that permits drop_database(...).

Make deployment writes recoverable.
Line 256 writes the rule before Line 260 writes main.sml and before Line 262 updates deployment state. If either later operation fails, the engine can observe a new or partially written rule while the API reports failure and the database still shows the draft as undeployed.
Write each file through a temporary file and atomic replacement. Preserve prior contents and restore them if a later filesystem or database operation fails. Add regression tests for a main.sml write failure and a Rule.mark_deployed failure.

Flask 1.1.4 Request.get_json silent=True malformed JSON returns None source documentation
💡 Result:
In Flask 1.1.4, when request.get_json(silent=True) is called and the incoming data is malformed (i.e., not valid JSON), the method returns None [1][2][3]. This behavior is defined by the silent parameter: if set to True, Flask catches the ValueError triggered by the JSON parser and returns None instead of raising an exception or invoking the on_json_loading_failed error handler [1]. Important Considerations: 1. Caching Behavior: In versions prior to the 1.1.4 fix, calling get_json(silent=True) on malformed data would cause the resulting None to be cached on the request object [4]. This meant that subsequent calls to request.get_json (even without silent=True) would return None instead of raising the expected error [4]. Flask 1.1.4 explicitly addressed this by ensuring that the result is not cached when parsing fails while silent=True [5][6]. 2. Official Documentation: The API documentation for get_json specifies that silent=True causes the method to "fail silently and return None" when parsing fails [1][2][3]. Source Documentation: The source code for flask.wrappers.Request.get_json in Flask 1.1.x implements this logic within a try-except block: try: data = _get_data(self, cache) rv = json.loads(data) except ValueError as e: if silent: rv = None else: rv = self.on_json_loading_failed(e) # The fix ensures if silent is True and parsing failed, # the cache logic is bypassed or handled correctly.

Reject malformed JSON before applying request defaults.
For Content-Type: application/json, get_json(silent=True) returns None on parse failure. The marshaller converts it to {}, so wire_into_main defaults to False and deployment proceeds. Return 400 for malformed JSON while preserving empty-body support. Add a regression test.

This one is ending up being a bit more of a broader fix overall, as we've multiple different places where we have marshalling code for json request bodies, and that's probably not correct.
Contributor
There was a problem hiding this comment.
@ThisIsMissEm, agreed. A shared fix in the JSON request marshalling layer is preferable. It should distinguish an absent or empty body from malformed JSON consistently across all affected endpoints.
Please preserve optional-body behavior and add regression coverage for each affected marshaller contract.

@ThisIsMissEm, I reviewed #502. The shared json_object_body() implementation preserves empty-body behavior and returns HTTP 400 for malformed JSON before the view can deploy a draft.
When #487 is rebased or merged with #502, replace the local ViewArgAndOptionalJsonBodyMarshaller in validators/rules.py with the shared marshaller. This will apply the fix to the rules endpoints.

Learning: In the Osprey Flask UI API, JSON request-body marshalling exists in multiple locations. Changes to malformed-JSON handling should be evaluated as a shared marshalling-layer concern, rather than as an isolated fix in `osprey_worker/src/osprey/worker/ui_api/osprey/validators/rules.py`.

Using Claude to help review since this is a chonky PR!
a "successful" deploy never reaches the running engine; it takes effect only on process restart. Deploy is allowed only when OSPREY_RULES_PATH is set, which is exactly the config where the engine runs StaticSourcesProvider, whose set_sources_watcher is a no-op (sources_provider_base.py:41-48);
_handle_updated_sources never fires. The one provider that hot-reloads (etcd) is explicitly refused. So deploy writes the file, appends the Require, marks the row DEPLOYED, returns 200, and traffic keeps evaluating the old ruleset with nothing signaling a restart is required.
This would essentially not work, I think

@julietshen this matches the behaviour you originally had, however, I do agree that it's probably a problem. I'm just not sure how to fix it correctly.

@julietshen I think fixing this is a much harder challenge than it may appear:
- We don't currently implement deploying to etcd (a write operation)
- We also are needing to reload across different containers, so just writing to disk like we do now wouldn't be easily picked up by another container on a different compute node without network attached storage.
We could arguably use LISTEN/NOTIFY in postgresql to let the ui-api notify the worker that the rules have changed, and then the worker would do it's own write to disk and reload the rules for the engine?

i think the unique rule_name guards client metadata, not the rule the SML actually defines
rule_name is free-text (identifier regex only), never compared to the X = Rule(...) in the source (the repo's own test creates rule_name='FirstRule' over SML defining SomeRule). Two drafts can each define Shared = Rule(...) under different rule_names, both pass the unique check and both validate (a draft's SML isn't visible to another's validation), then deploying both writes two files defining Shared → duplicate-rule engine-load failure.

I think it'd fail because before deploy there's a check that ensures everything compiles together. So you'd deploy one and then go to deploy the other and encounter an error that would need to be fixed.

looks like draft edits are last-write-wins with no compare-and-set. upsert uses ON CONFLICT (path) DO UPDATE with no WHERE/version guard, so two concurrent editors of the same path silently collide with each other which will lose an update, and author_email flips to whoever saved last, with no error.

This is true, but I'd consider it a follow up to wire through CID on save, such that we can detect if the current version is different from the CID the edit is being made on.

re-gating GET /rules to CAN_VIEW_RULES breaks the Rules page for existing adopters. The frontend loads /rules and renders the nav unconditionally (no ability gating), and only super_user.json / rule_author.json grant the new permission. Any ACL that had CAN_VIEW_DOCS but not CAN_VIEW_RULES would now gets 401 until each ACL is hand-edited

Yeah, that's why I listed it as a breaking change. I think it's better to make this one time fix, since require_ability can't do an OR between two abilities. The rules definitely aren't documents which are a separate endpoint.

We could arguably expand the GET /config endpoint to include a full permissions object, which would allow us to hide menu items you don't have access to?

Okay, have split out a bunch of commits from this pull request into separate PRs (they're still in #487 as it needs all those pieces to be worked on easily):
Also opened: |
Postgres compares `text` case-sensitively, so `rules/spam.sml` and `rules/Spam.sml` are two rows. On a case-insensitive filesystem -- the macOS default, so every developer's machine -- they are one file. Deploying both wrote one file and silently discarded one of the drafts, while the table went on showing two. The same gap made the reserved-name guard narrower than it reads. `create_draft` compared `path == 'main.sml'` exactly, so a draft saved as `Main.sml` passed it and then deployed over the engine's entry point, breaking the next rule load. The validate endpoint's warning had the same exact-match comparison. Rather than reconcile two case models, the set of representable paths is narrowed until they cannot disagree: `VALID_PATH` is lowercase-only. Every rule shipped in `example_rules` is already lowercase snake_case, and no test used anything else, so this writes down the existing convention. Rule *names* are untouched -- those are SML identifiers and stay CamelCase. Both reserved-name comparisons are now case-insensitive as well. `VALID_PATH` makes them unreachable for uppercase input, which is the point: a guard that reserves one spelling of a filename is one loosened regex away from reserving nothing. The table enforces it too, via a unique index on `lower(path)`, with `upsert` arbitrating ON CONFLICT on the same expression so a collision is absorbed rather than surfacing as a `UniqueViolation` -- which `upsert` reports as `RuleNameTaken`, and which would have been wrong. The read-back after DO UPDATE matches case-insensitively for the same reason: `path` is not in the mutable set, so the row keeps the casing it was first stored with. `test_rules_table_has_exactly_one_reachable_unique_constraint` could not see this coming: it inspects `__table__.constraints`, and `Index(unique=True)` lives in `__table__.indexes`. It would have kept passing while the premise it documents became false. `test_rules_table_has_no_unabsorbed_unique_indexes` covers the other collection. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PPgvKLEB4FrubcAD7paJTP
The index enforced "no two paths differing only in case", but the invariant chosen is "paths are lowercase", and those are not the same. A caller writing a single `rules/Spam.sml` with no existing row satisfied the index and stored mixed case -- and catching writes that bypass the API is the only reason the storage layer has a say here at all. `CHECK (path = lower(path))` states the invariant instead of an implication of it, and rejects rather than lowercasing on write: a row that quietly says something other than what the caller wrote is how a path and a filename come to disagree in the first place. It is also the smaller change. If every stored path is lowercase then `path`'s existing unique constraint is already case-insensitive uniqueness, so ON CONFLICT goes back to `path` and the read-back after DO UPDATE goes back to an exact match. A check violation is an IntegrityError that is not a UniqueViolation, so `upsert` re-raises it instead of reporting a rule-name conflict. `test_rules_table_has_no_unabsorbed_unique_indexes` now asserts the set is empty rather than naming an index. The premise it guards is unchanged -- a unique index that ON CONFLICT does not arbitrate on would be misreported as `RuleNameTaken` -- and asserting emptiness is what makes the next one added have to justify itself.

`^[a-z0-9_/-]+\.sml$` put `/` in the character class, which let a slash appear anywhere: `rules//spam.sml` matched. That is a distinct string, so a distinct row under `path`'s unique constraint, but `Path.resolve()` collapses it to `rules/spam.sml` -- two drafts claiming one file, which is the failure the lowercase rule exists to prevent, arriving by a different route and not limited to case-insensitive filesystems. It also matched `rules/.sml`, which names no rule. Written as `(?:[a-z0-9_-]+/)*[a-z0-9_-]+\.sml` instead, so every segment has at least one character. The checks in `_check_path` are reordered as a consequence: specific failures first, the general pattern last. The tightened pattern refuses absolute paths too, so running it first would have swallowed "must be relative to the rules directory" the way it was already swallowing "contains a parent-directory segment" -- `..` contains a `.`, which no version of this pattern has ever allowed, so that branch has been unreachable since it was written. It is live now, and tested. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PPgvKLEB4FrubcAD7paJTP

Enforce the full path grammar in the database constraint.
path = lower(path) accepts rules//spam.sml and rules/.sml. Rule.upsert can therefore persist paths with invalid segments when a caller bypasses API validation. This contradicts the storage backstop described here and the required non-empty lowercase path segments.
Extend the database constraint to enforce the complete allowed path format. Add regression cases for empty and dot-prefixed segments.

I don't think a database can do such a check constrain without a complex function?

🤖 web_search executed:
PostgreSQL documentation regular expression match operator CHECK constraint ~``
Length of output: 20444
@ThisIsMissEm, PostgreSQL can enforce this directly with its case-sensitive regex operator, ~. It does not need a database function.
For example:
CheckConstraint(
"path ~ '^([a-z0-9_-]+/)*[a-z0-9_-]+[.]sml$'",
name='ck_rules_path_is_valid',
)This accepts lowercase path segments and a lowercase .sml filename. It rejects uppercase paths, rules//spam.sml, rules/.sml, and dot-prefixed segments.
The constraint should replace path = lower(path). Regression tests should verify that direct storage writes reject the invalid paths.

Description
This pull request supersedes #402, taking the original work, and refactoring it heavily to reorganise code to hopefully improve maintainability, whilst also tackling a few bugs found and improving user experience.
