The `w1-test-doubles` task: the in-memory seams every later wave's
contract tests run against, behind their production seams.
- tests/common/mod.rs — the doubles, test-only (nothing reachable from
lib.rs, no feature): MemIdentityProvider (registered fingerprints ->
alkcall Identity resolutions over the IdentityProvider trait; token
path resolves none per ADR-004), TestVault (a wrapper over alkvault
0.1's shipped in-memory construction — resolving the flagged
vault-double question: wrap, not re-impl), MemHostKeyPolicy
(exact (host, fingerprint) rules + explicit default verdict,
fail-closed by default, inspectable decision log), and the fixture
table. Module docs record the location/vault/fixture decisions and
the row/stamp discipline (greppable Contract stamps).
- tests/vectors/ — one unified fixture set: four ssh-keygen-minted
ed25519 keypairs (committed .key + .pub + fingerprints.txt recorded
from ssh-keygen -lf, OpenSSH_9.6p1). The previous inline PEM
constants in src/key_source.rs were rejected by OpenSSH itself
(russh-only decodable); all keys were re-minted and the overlapping
vector set retired — one fixture set now serves the parity tests,
the custody round-trip, and every later auth/mapping test
(src-unit tests share it via include_str!).
- tests/doubles.rs — the end-to-end rows: register -> resolve,
seal -> source -> decode (+ locked/absent/tampered postures),
host-key set in order, policy verdicts honored-and-logged.
- tests/fingerprint_parity.rs and src/key_source.rs tests moved onto
the shared fixture files; src changes are #cfg(test) only.
Verification: cargo test (33 + 9 + 5 green; --all-features also green),
cargo clippy --all-targets -- -D warnings clean, cargo fmt --check
clean, taskgraph validate ok (12 tasks).
