AMT coverage: g2-knownmeta-normalize-norm - #185
Conversation
…tore CAS Adversarial mutation-test coverage for the g2 slice: normalize's AuthoringMetaV1 abi/json arms and default passthrough, search / search_deployer fan-out + hash lowercasing + first-success semantics, implements_i_described_by_meta_v1 decode-failure fold, NPE2Deployer corruption checks, the whole Store CAS surface (create/add_subgraphs/ get_deployer/search_deployer/search_deployer_check/set_deployer*/ dotrain getters/delete_dotrain/merge/update/update_check/update_with/ set_dotrain/store_content), bytes32 utf8 error path, and the GraphQL query processing (get_authoring_meta, process_meta_query, process_deployer_query). Every test was written against a probed surviving mutant and verified red under the mutation, green on baseline. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
WalkthroughThe pull request adds unit and integration tests for metadata normalization, querying, deployer discovery, Store behavior, Dotrain lifecycle operations, CBOR extraction, hash validation, and UTF-8 errors. ChangesMetadata behavior tests
Estimated code review effort: 3 (Moderate) | ~30 minutes Merge Risk: 🔵 Low · up to The PR adds broad adversarial coverage and is generally mergeable, but one cache-key test fixture conflates distinct identifiers, leaving the intended lookup behavior insufficiently demonstrated; owner awareness or a follow-up test adjustment is recommended. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

- Around line 1797-1830: Update test_store_search_deployer_populates_caches to
use distinct values for the searched meta_hash and the deployer_json_body
bytecode_meta_hash, then search_deployer by the bytecode_meta_hash. Adjust
assertions and cache lookups as needed to verify the record is retrieved under
the correct key and that meta_hash remains distinct.
In `@crates/cli/src/meta/query/mod.rs`:
- Around line 329-344: Add table-driven test coverage for every early-failure
branch in process_deployer_query: missing bytecode, parser, store, interpreter,
or deployTransaction; invalid meta length; and invalid constructorMetaHash or
constructorMeta hex. Build each payload from the full deployer_json_body shape,
omitting or corrupting exactly one required field per case, and assert each
request returns Error::NoRecordFound.

Adversarial mutation-test coverage for group g2-knownmeta-normalize-norm (30 behaviours across
KnownMeta::normalize, metasearch/search_deployer/implements_i_described_by_meta_v1,NPE2Deployer+StoreCAS, and the GraphQL query processing), scanned at bba50a7.78 exact-string mutants were probed with
mutation-probeagainst the pre-existing suite first (attribution pass), then against the suite with the new tests. Final score: 78/78 KILLED — 9 by pre-existing tests, 69 by the new tests in this PR. Zero NO-RUN, zero HARNESS-ERROR, zero surviving.Adversarial findings filed during this run (audit + adversarial labels): #161, #163, #169, #170, #172, #174, #175, #176.
