timothy	b83e965994	docs: make subagent use explicit, and turn "claim an issue" into a check rather than a label ... Two rules that were implied but not enforceable, both demonstrated by ersatztv#649 being implemented TWICE in parallel to completion on the same day. Subagents. The kickoff's HARD CONSTRAINTS already require parallel disjoint slices, mandatory independent review from a cold brief, and a named model/effort per dispatch — none of which is satisfiable without delegation. But nothing said so outright, and a generic client preamble of the form "do not use the Agent tool unless the user requested it" reads as a prohibition. Now stated plainly in both CLAUDE.md (always loaded) and the kickoff (pasted per session), with what to delegate and what to keep inline. Claiming. `in-progress` prevents duplicate PICKUP, not duplicate WORK — the record already said so, but step 3 told you to apply the label and nothing else. It now requires four checks first: an open PR whose body says `fixes #N`, a remote branch naming the number, a claiming comment predating the label (exactly what select-queue.sh's CLAIM? flag raises and deliberately leaves unresolved), and a fresh git fetch. Each fails differently; all four are cheap. Staleness. The second half of the #649 collision was reading origin/main once, at branch time, and not again across hours and four review rounds. A branch on a stale base computes its diff against that base, so `git diff origin/main` shows other sessions' merged work as DELETIONS and pushing it reverts them. Re-fetch before every push, rebase when it moved. process.parallel-session-claim carries the incident, including what worked: the merged implementation was better in one respect and the discarded branch's test coverage was salvageable, so diff the two before discarding yours.	2026-07-27 07:44:25 +02:00
timothy	fba5233caf	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. refs #610	2026-07-25 19:45:09 +02:00
