- requirements.md (new): the three use cases pinned as REQ-1..4 with
the node/pool/fleet/engine vocabulary defined once — ends per-session
re-derivation of consumer facts. REQ-2 (replicator fleet over one
shared pg pool, incl. large-blob serving) is recorded as a planning
fact predating all POCs, on the operator's authority.
- ADR-008: Backend trait gains size(key) length probe (before any
backend ships data — ADR-002 one-way-door discipline); fleet GC
mechanism (DB-backed pin rows committed atomically with entries,
TTL+renewal semantics, liveness = embedder-owned table, protect
callback is single-node-only, advisory-locked single sweeper,
staged re-arbitrated delete window on both engines); fs tier becomes
engine-selectable (local default; pg-lo named candidate) with the
fleet locality contract (shared media or re-routing; mixed tiers are
a documented deployment invariant, not a constructor-provable one).
- poc-pglo-spec.md (new): POC #7 spec — pg Large Objects as the fs
tier's pg-lo engine; instruments, decision gate, registered in
phase-0.md OQ-BL-06.
- ADR-003/005 status amendments point to ADR-008's extensions; specs
ripple (backends/store-api/gc/ops/overview/README).
- open-questions.md: deferral-policy header gains the decisions-vs-
sequenced-work distinction; pg-lo's why-not-parked audit trail
recorded.
- research fixes: postgres POC renumbered #4->#5 to the canonical
register (phase-0 OQ-BL-06), redb cross-refs fixed, thinking-
artifact sentence in B1 replaced with the honest reading.
Verification: docs-only change; reference-integrity sweep across the
tree (ADR/REQ/POC refs resolve); architecture-reviewer pass on the
delta — original 3 criticals addressed, its follow-up (fleet liveness
form, pin TTL, staged-delete semantics, enforceability, shared-media
caveats) fixed in this commit.
