test(validation): add snap token TTL validation and permission cache key generator assertions - #3142
Conversation
…key generator assertions
📝 WalkthroughWalkthroughAdded validation tests for snap-token TTL acceptance and rejection boundaries. Added a test for permission-cache key generation using tenant, entity, identifier, and permission components. ChangesWave 6 validation
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to This change adds token-expiry and permission-cache-key tests, but they currently validate local test logic instead of the production behavior. As a result, stale-token handling and cache-key isolation can regress without these tests detecting it; retarget the tests before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@internal/validation/wave6_token_cache_test.go`:
- Around line 15-20: Update the isSnapTokenValid test to cover the exact TTL
boundary: assert that now-ttl is valid and now-ttl-1 is expired, while
preserving the existing within-TTL and beyond-TTL checks.
- Around line 8-10: The test file’s local isSnapTokenValid and generateCacheKey
closures do not correspond to production behavior. Remove the TTL validator test
and retarget the cache-key coverage to engines.GenerateKey using a real
base.PermissionCheckRequest, including the existing hashing flow; only retain
TTL tests if a production validator is introduced.
- Around line 31-34: Replace the local generateCacheKey assertion with tests for
the production engines.GenerateKey function using validated requests. Cover
identifiers containing permitted ':' and '@' characters, assert the expected
check|... output and resulting hash behavior, and remove reliance on the local
formatter closure.

Retarget or remove these tests; they do not match production contracts.
isSnapTokenValid and generateCacheKey are local closures. The repository has no corresponding snap-token TTL validator. internal/storage/memory/snapshot.NewToken only stores time.Time.UnixNano(). The permission cache uses engines.GenerateKey(*base.PermissionCheckRequest, bool) and hashes its result. Test engines.GenerateKey with a real request, and remove the TTL test unless a production validator is added.

Add an assertion for the exact TTL boundary.
The test checks 100 seconds and 301 seconds. It does not check exactly ttl seconds. Add acceptance at now-ttl and rejection at now-ttl-1 after wiring the test to the production validator.

Test engines.GenerateKey with validated requests.
generateCacheKey is a local formatter and does not exercise production. Production uses engines.GenerateKey and hashes its check|... output. The request contract permits : and @ in some identifiers, so delimiter cases must follow the production field rules. Add cases around engines.GenerateKey, not this closure.
