- new ADR-017: GitSession is a real typed client in v1 (ls_refs/fetch/
push), grounded in the two deployment use cases — the p2p replicator
is the named downstream and needs the client protocol layer; the
thin-wrapper reading is superseded
- fetch client reuses gix-protocol (async-client) over a custom
alkcall gix_transport::client::Transport impl (handshake writes the
ADR-016 request line on the direct path; the channels open-op params
carry it otherwise); push hand-rolled to ADR-013's shapes (gitoxide
has no send-pack client)
- storage-agnostic: packs stream both ways to caller-owned consumers;
no in-session credentials (alkcall transport authenticates); client
sessions carry ADR-009 Limits (client is also internet-facing)
- manifest: gix-protocol/gix-transport gain async-client features
(verified against published tree, MSRV 1.88)
- amend ADR-010 (consumer-half bullet) and ADR-012 §4 (the deferred
gix-protocol call — resolved; rider superseded); backend/transport/
overview/doors wording; review 001 A-5 marked resolved
verification: cargo check (default, --all-features, --no-default-features,
--features sha256), cargo +1.88 check, cargo test, clippy
-D warnings, fmt --check — clean across the matrix
Resolves review 001 findings A-2 (critical) and A-6 (major) — the same
signature surface:
- ADR-012 §1: registry traits amended to #[async_trait] (bare async fn
in traits is not dyn-compatible, E0038; ops sit behind Arc<dyn
GitRegistryStore>). Desugared boxed Future form pinned in OQ-03's
freeze inventory. async-trait = "0.1" added to the manifest.
- backend.md concurrency model: the five-trait family is
#[async_trait] Send + Sync dyn-compatible; the wire layer enforces
ADR-009's pipeline-concurrency budget itself (permit acquired around
each GitPackGen/GitPackIngest call — the concrete admission point);
impls must not block the async executor and own their internal
threading (gix impls run spawn_blocking inside the impl — POC-2's
shape restated at its true layer).
- transport.md §fetch: spawn_blocking sentence rephrased to the
trait-contract version (the wire spec stops speaking gix).
- ADR-009: enforcement point of the blocking-pool budget made concrete.
- ADR-013 §6: ingestion spawn_blocking line aligned.
- review 001: A-2, A-6 marked resolved.
Verification: cargo test, clippy -D warnings, fmt --check, doc
--no-deps, check --no-default-features, check --all-features — all
clean.
Per ADR-012 §4: the gix feature now gates only the engine component
crates (odb/pack/ref/object/fsck); the gix facade crate (client
entry point) is removed — the impls drive components directly
(POC-2's shape). registry-file added as an independent default-on
seam (file-backed registry + record ops, no gitoxide). Both
default-on preserves the batteries-included story; --no-default-
features remains the wire-only embed.
Verification: cargo test (default + --no-default-features), clippy
--all-targets -D warnings, fmt --check.
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).
