feat(linkedin-studio): SB-S2 consolidation engine — proposeDiff/applyDiff [skip-docs]
Pure deterministic engine over the two-layer profile: add / reject-ai-draft /
evidence-bump / promote-at-N(3) / conflict-keep-both / decay-flag(90d). No-duplicate-id
guarantee: primary id = mintEntityId(observed,key), conflict-alt id =
mintContentId(observed-alt🔑:value::date) — byte-distinct. Folded profile-field
seeds immutable (different kind); static facts decay-exempt; no supersede (S3).
applyDiff produces the next ProfileDoc that round-trips through parse/serialize;
re-running is idempotent (bump, not duplicate). + consolidation-state.json sidecar IO.
12 engine tests (SC1a–g, SC2, SC3, SC4). brain 63→75, tsc clean.
