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.

The rule builder's Group nesting was capped at one level (#176's Kodi
model). Generalize it to recursive nesting bounded by a single shared
constant, MAX_GROUP_DEPTH (types.ts, = 5, root group is depth 0):

- parse.ts: replace the allowNested boolean with a depth counter that
  recurses to the cap; deeper input stays out of subset (null -> raw-text
  fallback), so parse remains the exact inverse of compile. Sub-group
  detection now requires the leading '(' to be the one closed by the
  trailing ')' (quote/escape aware), so '(a)x(b)' can't be mistaken for
  one wrapped group.
- RuleBuilder.tsx: 'Add group' is offered while depth < MAX_GROUP_DEPTH
  instead of only at the root; nested group boxes get box-sizing:
  border-box so per-level padding can't overflow (no global reset).
- roundtrip.test.ts: the 500-tree generator nests to the cap and asserts
  the corpus actually reached it; explicit depth-3 cases added to
  compile/parse/validation tests and a depth-gate test to RuleBuilder.

compile.ts and validation.ts already recursed correctly and are unchanged.
No backend/OpenAPI change.

Docs: spa-conventions.md §12; decisions lifecycle — new active record
spa.rulebuilder-nesting, predecessor spa.smartcollection-rule-builder
relocated to docs/decisions/archive/spa.md as superseded.
