hermes e78d9fcecd refactor(core): compile the mock provider only with a testing feature
Phase 3a of docs/DESIGN.md. MockProvider moves to api/mock.rs, and it,
the embedded MSN fixture bodies, and the IDX_MOCK_* hooks compile only
with idx-core's new `testing` feature. idx-cli enables it as a
dev-dependency, so `cargo test` keeps the fixture-backed provider while
release binaries no longer embed fixture data or honor
IDX_USE_MOCK_PROVIDER. Parser helpers used only by the mock are gated
the same way.

The packaged-cli flake check no longer relies on the mock; it checks
an offline cache miss (JSON CACHEMISS, exit 3) instead.

Goldens unchanged; clippy is clean with and without `testing`.

Docs:

  • docs/ARCHITECTURE.md: providers, ownership ingest/discovery, error and output contract
  • docs/CONVENTIONS.md: types, naming, testing, and git rules
  • docs/OWNERSHIP_SYNC.md / docs/OWNERSHIP_PUBLISH.md: snapshot consumer contract / maintainer publishing
  • docs/SMOKE.md: Nix checks, test layout, and the live drift check
  • docs/DESIGN.md: idx-core / idx-mcp design and parity gates
  • ROADMAP.md: open work

Rules

  1. Keep data access provider-driven; no ad hoc fetches in cli/.
  2. Keep parse/normalize functions pure.
  3. Tests use fixtures and IDX_USE_MOCK_PROVIDER=1 (needs idx-core's testing feature, on under cargo test); never hit the live network.
  4. Output contract: tables on stdout, one JSON document with -o json, errors on stderr (JSON-shaped in JSON mode), stdout empty on failure.
  5. Keep ownership queries (releases, ticker, changes, ...) working across every ingest path: XLSX, legacy PDF, archive ZIP/TXT, and snapshot sync.
  6. ownership import --fetch-bing is intentionally unsupported.
  7. Output parity is a contract: never edit golden files to make a change pass. After changing CLI behavior, run the live check and report its summary; report IDX 403s explicitly rather than counting them as passes.

Verify

nix flake check -L                       # canonical gate (fmt, clippy, tests, package)
nix develop --command cargo test <name>  # focused loop
scripts/live-smoke.sh --compare <old>    # live drift check, A/B against an older build
