Verifies and fixes CF-005 (alktunnels reverse-flow POC W1): the
connect-side serving path built channel 0 internally and never set an
identity, so a scope-gated serving op could only be satisfied via the
payload auth_token. Token is now the fallback (hub-forwarding /
browser path); transport/key-based identity is the primary path.
- ServingConfig gains identity: Option<Identity> — the explicit
override (remediation a). Semver-relevant struct-literal change →
0.7.0 (minor bump at 0.x, wire surface unchanged).
- from_connection_with_serving propagates the transport
Connection::identity() to the channel-0 connection via set_identity
before the serving loop starts (remediation b) — mirrors the accept
side's install-hook set_identity; process-local, nothing new on the
wire.
- Dispatch identity precedence on the serving loop: payload
auth_token → identity_provider, then ServingConfig.identity, then
transport identity; identity-less dispatch still fails closed
(FORBIDDEN).
- Public core::auth::NoopIdentityProvider (resolves nothing; the
ServingConfig::default() provider — three private test copies
existed).
- Regression gates: four cf005_* e2e tests (transport propagation,
override precedence, identity-less denial, token fallback +
precedence).
- Ledger CF-005 → resolved; ADR-022 §connect-side-serving amended;
README example updated; changelog 0.7.0.
Verification: cargo test (629) + --all-features (646), clippy
(all-targets, all-features, -D warnings), fmt --check, doc
--no-deps, wasm32 check, semver-checks (no update required at
0.7.0), publish --dry-run.
