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spa.rulebuilder-nesting, predecessor spa.smartcollection-rule-builder relocated to docs/decisions/archive/spa.md as superseded. fixes #436
Archive — superseded / retired decision records
This directory holds decision records whose status is superseded or retired. They are kept
verbatim (rationale prose untouched — see docs/decisions.md header and scripts/decisions_lib.py)
for history: why we changed our mind is the point, never silently rewritten.
They are out of the active startup path: scripts/decisions_lib.py active_files() /
all_active_records() do not glob this directory, docs/decisions/README.md (the active catalog)
never lists a record from here, and an agent doing task-router discovery should not need to read
this directory to find the current rule — follow a record's superseded-by key to the active
successor instead.
The lifecycle validator (scripts/decisions_validate.py) still enforces invariants here:
- a
superseded/retiredrecord MUST live under this directory, never in an active file; - an
activerecord MUST NOT live under this directory; supersedes/superseded-bykeys must resolve reciprocally to a record in the active set OR here;- a record moved here must not have its rationale prose changed in the same commit (unless the
commit message carries the
[decisions-edit]token, reserved for genuine rationale edits).
One file per topic cluster (e.g. ci.md, release-ci-governance.md), mirroring the active
docs/decisions/*.md topic-file split. See docs/decisions/migration-map.md for the legacy
heading → key → status → location mapping produced during the #521 lifecycle migration.
