feat(610): split the decision corpus into one YAML-frontmatter file per record
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.

process.pr-routine-sequence 2026-07-21 — The PR routine is a fixed sequence: validate locally, then push, then only follow-up commits (#542) active 2026-07-21 none none Worktree off origin/main → implement → regenerate API artifacts → full local tests + cold review + live-E2E ALL before the push → push, open PR, arm the CI monitor at open → fixes after the push are follow-up commits, never amend/force-push. PR routine · worktree off origin/main · `./scripts/update-openapi.sh` · `npm run generate:api` · cold-context review · CI monitor at PR open · no force-push on a pushed branch · derived-consent merge gate · paths: `scripts/update-openapi.sh`, `scripts/e2e-local.sh` · issues: #542 CI watch by commit status: `/api/v1/repos/timothy/ersatztv/commits/{sha}/status`. Merge via the derived-consent gate (`pretooluse-merge-consent.sh`).

The sequence: create a worktree off origin/main; implement; for API changes build the app project FIRST, then ./scripts/update-openapi.sh, then npm run generate:api (order matters — the generator reads the built app's spec). Then run the full local test pass, a cold-context adversarial review scoped to "review only", and live-E2E for UI/write-path changes — all before the push. Fold pre-push fixes into the branch; amend/reword is fine while nothing is pushed.

Then push, open the PR, and arm the CI monitor at open, not at the end. Once the branch is pushed, every further fix — a post-push cross-model pass, or a CI-surfaced issue — lands as a follow-up commit; never amend or force-push a pushed branch. On green, merge through the derived-consent gate and write the structured close comments the applicable AGENTS.md / CLAUDE.md protocol requires.
