Wave 1 task core-hashing-keys: the crate's declared one-way door,
implemented byte-exact to ADR-002.
- src/hashing.rs: Algorithm (exactly GitBlobSha256 canonical /
GitBlobSha1 tolerated; BLAKE3 absent), Digest (known-length
derivation H("blob <len>\0" + content) as primary constructor;
from_git_oid_hex interop constructor, lowercase-only acceptance),
and the hashing::registry constants (0x01/0x02, 0x00 reserved; new
algorithm = new ADR)
- src/keys.rs: typed Key wrapper; as_bytes/from_bytes are the only
backend-boundary conversions; 1 algorithm byte + digest bytes
(33/21 total); rejects-never-guesses validation -> Error::KeyInvalid
- tests/git_interop.rs: the load-bearing test — byte-exact derivation
against the `git hash-object` CLI, both algorithms, small and
75-KiB content; external-oid round-trip into pool keys; both oid
formats coexisting in one flat pool
- named design point (oid hex policy): lowercase-only acceptance,
recorded in the task Notes and on from_git_oid_hex
Verified: cargo test (15 passed), cargo clippy --all-targets -- -D
warnings, cargo fmt --check, cargo test --all-features — all green.
- docs/plans/implementation.md: the meta plan (alkstore pattern) — nine
waves, dependency logic, decided points, review gates. Scope authority:
v0.1.0 ships the full surface (all five engines, fleet GC, ops).
- Wave 1 decomposed: scaffold-crate-features, core-error-model,
core-hashing-keys, core-trait-and-types, suite-scaffold,
review-wave-1 (the one-way-door gate).
- Waves 2-9 shaped in the plan; each decomposes after the prior wave's
review gate.
Verification: cargo test / clippy -D warnings / fmt --check green
(docs-only change).
