docs/architecture/ now exists: README index, overview, five component specs (core-contract, engine-sqlite, engine-postgres, queues, deployment), ADR-001..007 carrying the Phase 0 resolved decisions (crate split, feature scope, per-engine drivers, dependency ownership, wake contract, tx seam), and the centralized open-questions tracker promotion: OQ-ST-01..08 mirror to OQ-01..08 one-to-one with statuses/resolutions carried; new Phase 1 questions append (OQ-09 scheduler collapse, OQ-10 contract versioning). Open Phase 1 work: OQ-04 contract pinning (high), OQ-05 queue semantics depth (high), OQ-06 honker-core quality read (high; fork-trigger gate), OQ-08 capability surface, OQ-09, OQ-10. Erratum fixed in phase-0 OQ-ST-04 (thread-affinity friction is SQLite-side, previously garbled as pg-side) and a stale scheduler- boundary pointer corrected in consumer-inventory.md. Two review passes run (findings: OQ-promotion numbering faithfulness, ADR back-reference sync) — all critical/warning findings resolved.

alkstore — Architecture
Architecture documentation for the alkstore project: one reactive store interface (notify, streams, queues, locks, scheduler, outbox) over SQLite and Postgres, with each engine native underneath (see overview.md).
Current State
Phase 1 (Architecture) — in progress. Phase 0 is complete
(docs/research/phase-0.md): both POCs ran and passed, the scope
inventory is confirmed, and the crate split, drivers, and ownership
postures are decided. This directory carries the architecture spec
build-out over that evidence base; all spec documents are draft
pending architecture review and OQ resolution.

Architecture Decision Records
| ADR | Title | Status |
|---|---|---|
| 001 | Reactive-core crate + per-engine crates | Accepted |
| 002 | Feature scope — inventory-confirmed surface | Accepted |
| 003 | SQLite engine — rusqlite + honker-core, bridged seam | Accepted |
| 004 | Postgres engine — tokio-postgres + deadpool, hand-rolled LISTEN | Accepted |
| 005 | Published libraries by default, named fork triggers | Accepted |
| 006 | Wake contract — opaque wake + re-read; notify-vs-streams split | Accepted |
| 007 | Transactional seam — caller-held TxHandle, *_tx methods |
Accepted |
Open Questions
Tracked in open-questions.md (OQ-01..NN; the Phase 0 register's OQ-ST-01..08 promote one-to-one — OQ-NN mirrors OQ-ST-NN — with new Phase 1 questions appended after). Highlights, in suggested resolution order (OQ-04 first):
- OQ-04 (high): contract pinning — exact trait shape, handle representation, error taxonomy, reserved strings, guarantee rows for locks/scheduler.
- OQ-05 (high): queue semantics depth — retry/backoff/dead-letter/ sweep design.
- OQ-06 (high): honker-core quality read — fork-trigger gate.
- OQ-09 (medium): scheduler as first-class mechanism vs queues +
schedule(). - OQ-08 (medium): capability-surface shape.
- OQ-10 (medium): contract versioning across engine crates.
Resolved (Phase 0, kept with resolutions): OQ-01 (feature scope), OQ-02 (crate split), OQ-03 (drivers), OQ-07 (extension surface cut).
No deferred OQs: all open questions are actionable Phase 1 work with complete evidence bases.

Provenance of decisions
Phase 1 inherits its decisions from Phase 0's evidence base — every Accepted ADR above cites its POC findings and register record. The research documents remain the deep background:
docs/research/phase-0.md— vision, prior art, OQ-ST register, convergence.docs/research/consumer-inventory.md— per-feature scope evidence.docs/research/poc-sqlite-posture-findings.md/docs/research/poc-pg-posture-findings.md— measured ground.
