- ADR-014: the multi-round ack loop, grounded in duplex git 2.43.0
captures cross-checked against fetch-pack.c: no-done rounds get
acknowledgments (ACK <oid> per recognized have, NAK when none, flush;
never ready so FLUSH is always the terminator), the done round
generates closure(wants) - closure(haves) with no cross-round server
state (clients re-send wants + commons every round), wait-for-done
stays (no capability change), want-less rounds answered empty, the
ack check is a new GitPackGen::common_haves seam (honest boundary at
the trait), budgets unchanged kinds
- docs/research/negotiation-captures.md: the normative negotiation
record (grammar, client behavior, malformed-section failure modes)
- transport.md: fetch section rewritten to the decided loop; references
updated
- OQ-02 resolved
Verification: cargo test / clippy -D warnings / fmt --check / doc pass
Structural decision (OQ-09 resolved): alkgit follows the alktty/
alktunnels template — a single published protocol crate on alkcall
channels, no binary, no front doors.
- ADR-010 supersedes ADR-001 (crate decomposition) and ADR-006
(http router factory); both marked Superseded
- Single crate at repo root: Cargo.toml with gix feature (default-on
backend implementations; wire layer compiles without it —
gix-hash always-on with sha1 per the compile-time-rejected
invariant), crates/ workspace deleted, src/lib.rs stub in place
- doors.md replaces http.md/ssh.md/alkgitd.md: alkhttp git-feature
sequencing (after first publish), alkssh requirement (fixed-grammar
exec dispatch), native alk/git path, downstream assembly
- backend.md replaces storage.md: GitRegistry/GitRefs/GitPackGen/
GitPackIngest traits (ingest validates, refs commits — single CAS
home), gix feature encodes POC-2 prerequisites
- transport.md reframed for the single crate; backend traits replace
hook traits in the public API
- OQ-09 resolved (all five sub-decisions in ADR-010), OQ-01 resolved
(subsumed), OQ-03 narrowed to publish-freeze, OQ-08 narrowed to
registry identity + vault placement, OQ-07 rescoped to the gix
feature's registry impl
- vision.md v2: single-binary/monorepo framing corrected as
init-agent artifact; POC checklist marked complete
- AGENTS.md + .opencode agent specs updated to the new shape
Verification: cargo build (default + no-default-features), cargo test
--all-features, clippy --all-features -D warnings, fmt --check all
pass. Third review round: zero critical, all warnings/suggestions
addressed (GitPackGen signature amended in ADR-004, stale anchors
fixed, ADR-006 body tense normalized, CAS split stated, vision
residuals cleaned).
New open question capturing the doors-as-family-infrastructure
direction: alkssh (planned) becomes the ssh door for git, git is a
payload service exposed by downstream doors (alkhttp, alkssh, alknet),
and the crate set may slim to protocol crates + http adapter (kept in
alkgit, Slim-A, or promoted to an alkhttp git feature, Slim-B).
OQ-09 carries the three sub-decisions (alkgit-ssh deletion vs
temporary russh scaffolding; http adapter home; alkgitd consumption
path) and cross-references ADR-006 (now flagged as possibly superseded
before finalization) and OQ-01. Deferred summary table updated.
