Second sub-slice of SB-S3 (after S3a's reader landed). Adds an operator-gated,
explicitly-signalled supersede op to the consolidation engine: a temporal-update
candidate retires a stale fact (status: superseded, re-minted to an archival id,
replaced in place, retained as audit) and installs the new winner under the
canonical key-id. Bounded to scripts/brain/ — pure, deterministic, fully
unit-testable.
Operator-confirmed scope: temporal-update→supersede ONLY · winner→dynamic
(re-earn) · minimal `supersedes?: string` · retain superseded as audit.
Light-Voyage-hardened:
- brief-reviewer APPROVE-WITH-FIXES — 8 FIX folded (the load-bearing one: id
lifecycle → winner-takes-key-id, retired fact re-minted, so mintEntityId(key)
always points at the live fact).
- plan-critic REVISE → 2 BLOCK + 6 FIX folded: applyDiff must REPLACE-IN-PLACE
(not copy → would dup the canonical key-id); proposeDiff must value-guard the
supersede fork (a re-sent stale signal would self-supersede every run); plus
--gather active-only filter + decay excludes superseded (else retired facts
leak back as live context / spam stale flags).
- scope-guardian ALIGNED (0 creep / 0 gap).
Also reconciles brief-sb-s3a.md's stale DRAFT status (S3a landed 4fa411f).
No code yet — awaiting go-before-code.
