timothy 685926a0d0 fix(807): derive the coverage boundary instead of writing it down a third time
Round 2 returned BLOCKED. The enumeration added in the previous commit was
itself incomplete: it omitted `ArtworkContentTypeModel`, which carries three
members outside its `required` array and is reachable from the full-replace
`PUT /channels/{id}` via `UpdateChannelRequest.logo`. It was sorted out on its
name — `...Model` reads as a response model — which is the same failure the
enumeration was written to eliminate one level up, and it closed with a false
universal negative ("the remaining schemas ... are never request bodies") sixty
lines below this document's own warning against exactly that.

Two misses from one mechanism, so the mechanism goes rather than the list
getting a third patch.

`scripts/tests/test_optional_request_members.py` derives the population every
run from `ErsatzTV/wwwroot/openapi/v1.json`: every schema with a property
outside `required` that is TRANSITIVELY reachable from a POST/PUT/PATCH request
body, asserted set-equal in both directions against a registry of per-schema
dispositions. Transitivity is load-bearing — `MultiCollectionItemRequest` and
`ArtworkContentTypeModel` are both nested, so a top-level-only check would have
reproduced both misses. Population derived, dispositions hand-written as the
reviewed SCOPE, per testing.guard-derives-population-from-source.

Witnessed red: removing the `ArtworkContentTypeModel` disposition reports it as
MISSING with its three members. That mutation is DECLARED in
`mutation_manifest.py` and re-applied every suite, so the row grades MUTATION
rather than resting on this message. Renaming the key rather than deleting the
entry keeps the module importable, so the red is the MISSING direction and not
an ImportError reddening for the wrong reason.

ArtworkContentTypeModel's real disposition is COMPUTED, not COVERED: the three
members are get-only properties derived from `Path` and are never deserialized,
so omitting them drops nothing — and `Complete<T>` must NOT be applied there,
because it would force a caller to fabricate server-computed values in an
outbound request. That caveat is now in spa-conventions §4b, where a reader
following "annotate each construction site" would otherwise have produced a
wrong payload.

Also reconciles the contradiction round 2 found between the wrapper-boundary
rationale and the snapshot: 13 of ~33 full-replace PUT wrappers carry
`Complete<>` today. The rest are stated as still contingent — the difference
from before is that the contingency is now MONITORED by the derived test rather
than assumed.

L5 the phantom denominator is ten sites, not nine (five accepted, three of those
without a spread or a local). N6 fixture field placed alphabetically. N7 the
record's three-act framing trimmed to the current statement plus the rejected
one, so a cold reader does not have to work out which is live.

Verification: 879 passed 2 skipped in scripts/tests (up from 874), typecheck 0,
eslint 0, 1200/1200 web tests, web build 0, catalog check clean, doc-narrative 0.

docs/ — task-signal map

Purpose: route a fresh contributor/agent to the minimal set of docs for the task at hand, instead of a mandatory front-to-back read. Update this doc in the same PR that adds, removes, or retitles a doc below, or that changes which sections a task signal points to.

Start here, always

  • CLAUDE.md (repo root) — project intro: architecture, layout, dev commands, conventions, Task Completion Protocol.
  • docs/contributing.md — established code patterns (CQRS/MediatR, LanguageExt, the ChicoryTV SPA, EF Core dual-provider migrations, FFmpeg pipeline, analyzers, testing). Read before any non-trivial change.

Task signal → minimal sections

Signal Read

Proposing a new guard / CI check / regression test convention docs/defect-shapes-773.md §4 (detector menu + the classes where no detector is plausible), then the three rules every guard must satisfy: docs/decisions/records/testing/guard-derives-population-from-source.md, …/guard-ships-with-mutation-proof.md and …/mutation-claims-are-executed.md (a MUTATION grade carries a DECLARED clause mutation that is re-run every suite)
Testing a surface gated by config / an env var / a credential docs/decisions/records/testing/deny-path-at-production-config-value.md — cover the setting absent, at its production value, and each opt-out, and assert the DENY branch
Touching a full-replace write path or a hand-built request object docs/decisions/records/testing/full-replace-asserts-field-list.md — derive the field list from the DTO and assert set equality; reconcile by id where child state exists. In the SPA the same rule is enforced by the type system: docs/spa-conventions.md §4b — build the body as Complete<T>, annotating BOTH the wrapper parameter and every construction site
Writing or editing any doc, or answering a review finding in prose docs/decisions/records/docs/no-session-narrative.md — the doc records the END STATE; the path to it goes in the commit message. Apply the who-benefits test, and read the carve-out before you cut (dated measurements, stated snapshot boundaries and tested-and-rejected results stay)
Adding / changing / deleting a guard file docs/guard-inventory.md — every guard's row is machine-checked by scripts/tests/test_guard_inventory.py, so a new guard must acquire a row before the suite goes green, and a row graded MUTATION must also acquire a declared clause in scripts/tests/mutation_manifest.py
Writing code that reads live Gitea/remote state and then acts on it docs/decisions/records/process/check-and-use-pins-a-version.md, then docs/remote-state-inventory.md — a new executable under scripts/ (excluding scripts/tests/), .claude/hooks/, .husky/ or .gitea/workflows/ must acquire a row there before scripts/tests/test_remote_state_inventory.py goes green

"Why do we do X this way" / challenging a convention Catalog-first: docs/decisions/README.md (active rows) → follow the row's link to docs/decisions/records/<area>/<topic>.md for full rationale. docs/decisions/archive/<area>/ only for "what did the rule used to be."

Knowledge retrieval (MemPalace + catalog + Gitea)

These four rules are the seam agreed with server-management#642 (the Gitea→MemPalace exporter). They apply whether the question comes up via MemPalace, a grep, or a stale comment:

  1. Current conventions/decisions → catalog-first. Start at docs/decisions/README.md; discover via the ErsatzTV-Decisions wing (active) / ErsatzTV-Decisions-Archive (superseded/retired). Resolve by topic/key, never by chasing a file path.
  2. Issue history → evidence, not authority. The Gitea-ErsatzTV wing is historical narrative that may be stale; it never overrides current Markdown.
  3. The breadcrumb rule (the crux behavior change). A file path named inside a historical issue comment (e.g. "grep docs/decisions.md 2026-07-17", "see …") is a breadcrumb, not a live pointer. Find the current rule via the catalog / active wing by concept; do not treat the named path as current. (Why it's safe: still-current → in the active wing, breadcrumb resolves; superseded → the active wing returns the successor and a literal follow lands on a record that announces its own status: superseded; retired → the active wing returns nothing, which is itself the signal. The validator-enforced move-to-archive/ is what prevents the catastrophic "superseded rule read as current" case.)
  4. Fallback when MemPalace is stale/down: docs/decisions/README.md catalog, then rg '^`key: <dotted.key>`' docs/decisions/. MemPalace is never authority nor sole fallback.

MemPalace is candidate discovery only — every passage is verified against its cited Markdown/Gitea source before use. Never derive live queue state from MemPalace, #237, or historical comments; queue state is live Gitea state, retrieved via scripts/select-queue.sh (see docs/handoffs/chicorytv-issue-queue.md). Full retrieval contract (altitude/precedence, staleness bounds, what's mined per issue): docs/handoffs/chicorytv-issue-queue.md → "Knowledge retrieval".

Read before briefing an agent to find every site referencing a symbol.
  • docs/testing.md — testing map: what each *.Tests project / web suite covers, golden-file nets, the timezone-independence rule, how to run subsets, the per-PR verification gate.
  • docs/blazor-route-parity.md — historical record of the completed #91 phase (b) cutover: the Blazor Server UI is removed and every legacy route now 302-redirects to its SPA equivalent (or falls through to the catch-all → /app). Read it for the full legacy→SPA route inventory.
  • docs/decisions/records/<area>/<topic>.md — one active decision record per file, YAML frontmatter (key/title/status/since/supersedes/superseded-by, plus optional stale-after/sources — ersatztv#603), rationale prose in the body. The filename is the key, so one-active-record-per-key is a filesystem property (ersatztv#610). docs/decisions.md and the topic files remain as the lifecycle-schema narrative plus a "Records formerly in this file" index, which is what keeps older date-based pointers resolvable. Generated active view: docs/decisions/README.md (catalog / task router) — start there. Superseded/retired records live in docs/decisions/archive/ and are read only for history, never for "what is the current rule."

  • docs/endpoint-index.md — generated REST endpoint index (method/path/operationId/summary per OpenAPI tag). Do not edit by hand; regenerated by scripts/generate-endpoint-index.py / scripts/update-openapi.sh.
  • docs/handoffs/chicorytv-issue-queue.md — static session kickoff prompt + workflow lore. Queue state is live Gitea state, retrieved each session via scripts/select-queue.sh — see that file's standing kickoff for the two concurrent tracks (orientation ‖ selection). ersatztv#237 is a closed, archival historical tracker (superseded by startup.parallel-orientation in docs/decisions.md) — not a live pointer.
  • docs/defect-shapes-773.md — root-cause analysis of the recurring defect shapes across the whole closed-issue corpus (#773): the measured class ranking, the four families they consolidate into, the cheapest mechanical detector per class, the classes where no detector is plausible, and an audit of which configured hooks/MCP servers/LSPs are actually invoked. Read it before proposing a new guard or CI check — §4 is the detector menu, and it argues against enumerating cases one incident at a time.
  • docs/remote-state-inventory.md — every executable in scripts/ (excluding scripts/tests/), .claude/hooks/, .husky/ and .gitea/workflows/ that reads live remote state and acts on that read, classified PINNED / CAS / UNSAFE-KNOWN / N/A with the window and what bounds it. Code outside those directories — C#/TypeScript guards, web/, and the test suites themselves — is out of scope, and the doc states that rather than implying coverage. The population is derived from git ls-files and compared for set equality by scripts/tests/test_remote_state_inventory.py, so a new script that talks to a remote service cannot ship unclassified. Read it with process.check-and-use-pins-a-version; it is that record's detector, since the class has no plausible linter (docs/defect-shapes-773.md §4 detector D).
  • docs/guard-inventory.md — every executable guard file, what it blocks, whether it is a GUARD or TOOLING, and whether it ships a mutation proof (MUTATION / BEHAVIOUR-ONLY / NONE) with a file::function ref. The population is derived from the filesystem and the workflow/hook call sites and compared for set equality by scripts/tests/test_guard_inventory.py, so a new guard cannot ship unclassified and a renamed test cannot leave a row claiming coverage it has lost. Guards implemented inline in workflow YAML are deliberately outside that population — the doc states the limit rather than implying coverage.
  • docs/tracker-retrofit-triage-237.md — audit trail for the #524 triage of ersatztv#237's 111 comments (method, per-comment classification, totals). Evidence for the docs.tracker-comment-retrofit decision; read it only when triaging another over-cap tracker.
  • docs/handoffs/rest-api.md — original handoff prompt for kicking off the REST API work (#2).
