Completes review 001 D-1 (vision.md's half landed with ADR-015): - alk-stack.md gitea-lesson item 2: supersession note pointing at ADR-012 §3 / ADR-015 (repo ops are External, scope + manage grant — right mechanism, wrong axis). - AGENTS.md lifecycle status: active OQ list updated (OQ-03 partially resolved, OQ-05 deferred, OQ-16 deferred; OQ-04/06/08 resolved via ADR-013/012/011). - review 001: D-1 marked resolved. All three stale statements were pre-decomposition landmines: research docs are declared 'current source of truth' by AGENTS.md, so the superseded admin-API design needed marking.

|---|---|---|
| vision.md | Vision, guiding principles, non-goals, phase-0 checklist | draft v2 (amended 2026-09-21) |
| gitoxide.md | gitoxide (gix) capability + version alignment | initial pass complete |
| alk-stack.md | alk stack fit, integration surface, gitea-lesson constraints | initial pass complete |
| git-protocol.md | Server-side git smart protocol inventory (what we own) | initial pass complete |
| reference-policy.md | Licenses, reference projects, reuse policy | complete |
| pocs.md | POC plan (what to validate before architecture commits) | planned |
| poc-1-findings.md | POC-1: pkt-line over alkcall BiStream (duplex producer) | complete — proceed |
| poc2-findings.md | POC-2: server-side pack generation (streaming pipeline) | complete — proceed |
| poc3-findings.md | POC-3: smart-http shape through alkhttp (stateless substrate) | complete — proceed |
| push-captures.md | Normative receive-pack (push) wire record (real git captures) | complete — ADR-013 basis |
| negotiation-captures.md | Normative V2 negotiation record (real git captures + source) | complete — ADR-014 basis |
Key findings so far
- gitoxide covers storage + pkt-line; the server half of the smart protocol is ours to write (gix-protocol/transport are client-side).
- Published gix 0.87.1 == local clone base; pin crates.io versions.
- alkcall
BiStreamis the natural substrate under pkt-line for both ssh and http paths. - The incompatible-license prior art confirms feasibility but contributes nothing; policy in reference-policy.md.
gixwithdefault-features = falserequires an explicit hash feature; workspace pinssha1with asha256passthrough feature everywhere.
Convergence criteria (phase 0 → phase 1)
Phase 0 is done when POC-1..3 have results and a recommended-approach
summary is written here (append below). Then the Architect produces
docs/architecture/ per sdd_process.
Convergence (2026-09-21): phase 0 gates all pass (POC-1/2/3 proceed).
Phase 1 opened with docs/architecture/; the structural decision is
ADR-010 — pure protocol crate following the alktty/alktunnels template
(the v1 "monorepo + alkgitd binary" framing in these research docs was an
init-agent artifact, amended in vision.md v2). POC-1 maps to the producer
half, POC-2 to the gix backend implementation, POC-3 to the stateless
substrate consumed by alkhttp's future git feature.
