The engine can now RETIRE a fact via an operator-gated, explicitly-signalled
temporal-update supersede — completing the consolidation motor's one S2 TODO
("no supersede in S2 — that's S3"). A `supersedes` signal on a candidate retires
the stale fact (re-minted to an archival id, status: superseded, REPLACED IN
PLACE, retained as audit) and installs the new winner under the canonical key-id,
so mintEntityId(key) always points at the live fact.
- consolidate.ts: Candidate.supersedes? + ProfileDiff.supersedes (SupersedeOp
carries the full winner fact, so applyDiff stays a pure projector). proposeDiff
value-guarded routing fork (routes only when the target holds a DIFFERENT value —
else a re-sent signal would self-supersede every run) + intra-batch
first-supersede-wins guard. applyDiff replace-in-place + value-matched state-check
(oldId present, active, value===oldValue) → idempotent re-apply + stale-diff safe;
superseded facts never bumped/promoted (supersede wins). Decay excludes superseded.
archivalId seeded with the pre-archival id (collision-free).
- cli.ts: renderDiffMd `## Supersessions (old → new)` (rendered last, only when
present → zero-supersession diffs stay byte-identical); validateCandidates optional
single-line `supersedes`; `--gather` profileFacts filtered to active (superseded
archival facts never re-presented as live context).
- Tests: +12 brain (consolidate 10 + consolidate-cli 2). TDD: RED (6 fail) → GREEN
(94/94). BRAIN_TESTS_FLOOR 82->94; ASSERT_BASELINE_FLOOR unchanged at 80 (no new
test-runner.sh section). Gate 95/0/0.
- Docs: consolidation-loop.md rule table + honest-limit reconciled (the operator
gate is the only classification net); engine docstring updated.
All 13 success criteria deterministically tested (unlike S3a, no behavioural-only
SC). READ-only gate unchanged — brain consolidate --apply --confirm stays the sole
profile.md writer. Scope held: scripts/brain/ only; temporal-update only
(condition-dependent/distractor deferred).
