168 records -> docs/decisions/records/<area>/<topic>.md (163 active, 23 dirs) and docs/decisions/archive/<area>/<topic>.md (5 archived). The filename IS the key, so one-active-record-per-key becomes a filesystem property rather than a validator check, and supersession becomes a `git mv`. WHY: the monolith was a concurrency problem before an aesthetic one. A 3,900-line append target made parallel sessions collide -- PR #605 and PR #614 both hit append-vs-append conflicts during routine rebases, and hand-resolving those inside the corpus is exactly the operation the rationale-rewrite guard exists to police. HOW IT IS VERIFIED: a ~170-file diff cannot be meaningfully read, so correctness does not rest on reading it. The parser was taught BOTH formats first, so the body-diff guard parses the old form at the merge-base and the new form at head -- the migration validates itself, no bypass. The proof is a field-level equivalence harness: 168 records before and after, zero lost, zero gained, zero field mismatches, zero rationale bodies differing. Reviewers should scrutinise the harness; it is the actual evidence. What measuring caught that reading would not have: - ~500 lines sit OUTSIDE any record -- decisions.md's lifecycle schema and each topic file's preamble, mostly the only copy. Source files are kept and stripped, never deleted. They also cannot be filed per-area: topic files hold several areas and 4 of 23 areas span several files. - Archive discovery was a non-recursive glob; after the split it found ZERO archived records, surfacing as four bogus "supersedes points to unknown key" errors rather than an obvious failure. - ~32 live docs point into the corpus BY DATE, which the split dangles. Each stripped file now ends with a generated "Records formerly in this file" index, which also rescues the identical breadcrumbs in old issue comments. - decisions.md's "In this file:" list was 97 same-file anchor bullets that the split makes WRONG, not merely stale. Dropped; the generated index replaces them with links that resolve. The equivalence harness now runs against a checked-in FIXTURE, not the live corpus. The earlier version migrated the real tree, which made it a one-shot: the moment the migration landed there was nothing left to move and the tests failed for reasons unrelated to the code. A fixture keeps them testing the SCRIPT rather than the repo's current state. Keys preserved verbatim, warts included: `sched` (12) and `scheduling` (1) remain two directories for one concept. Renaming a key is not a move -- it changes identity, breaks the equivalence proof, and invalidates MemPalace's per-key drawers. Taxonomy normalisation is separate work. refs #610

| docs.convention-docs-session-start | 2026-07-07 — Convention docs read at session start, updated in-PR | active | 2026-07-07 | none | none | Docs-first, not source-first: conventions (api-conventions, spa-conventions, e2e-local, blazor-route-parity, domain-model, decisions, README) are read from docs, not reverse-engineered from code, via `docs/README.md`'s task-signal map — only the sections it points to for the task at hand, not the whole set. Each doc is updated in the same PR that changes what it documents, replacing deferred/follow-up doc updates. | `docs/README.md` index, `ApiControllerSecurityTests` drift · paths: `docs/README.md`, `docs/api-conventions.md` §6 · issues: #184, #185. Session-start *reading order* is now the task-signal map — see `startup.parallel-orientation`. | `docs/README.md` |
docs/api-conventions.md, docs/spa-conventions.md, docs/e2e-local.md,
docs/blazor-route-parity.md, docs/domain-model.md, docs/decisions.md, and docs/README.md
are the standing reference set every ChicoryTV session should read before starting work, and each
one carries an explicit "update this doc in the same PR" rule rather than deferring doc updates to
a follow-up. These docs replace per-session recon — an agent reads the index
(docs/README.md) and the relevant convention doc instead of re-deriving conventions from the code
each time it starts API/SPA/E2E/parity work. A testing map and a generated-endpoint index are
tracked as still-to-come under #185. Drafting this doc set also surfaced a drift in
ApiControllerSecurityTests.cs's hardcoded controller registry (several controllers under
ErsatzTV/Controllers/Api/ are missing from it — see docs/api-conventions.md §6) — tracked as a
follow-up under #184 rather than fixed inline, since it's a pre-existing gap, not something this
doc-drafting pass caused.
