[Functional.Check] 🟡 RESTRICT

Test name claims to verify that stale:true causes stale cache values to be returned before deletion, but the body only asserts that the LRUDiskCacheOptions object echoes back the literal values it was constructed with (options.stale === true, options.maxAge === 5000). No actual cache/LRU behavior is exercised since typings.ts only exports type declarations — this gives false confidence that stale-read behavior is covered.

Action: Rename the test to reflect what is actually checked (e.g. 'should accept a stale boolean option'), or move real behavioral coverage of stale-read semantics to the test suite for the LRUDiskCache implementation itself.

[Functional.Check] 🟡 RESTRICT

Test name claims stale:false causes 'undefined for stale entries' to be returned, but the assertion only checks options.stale === false on the literal object passed in. No cache lookup or stale-entry logic exists in this file to substantiate the claim, since typings.ts is a type-only module.

Action: Rename to describe the actual assertion, or relocate behavioral verification of stale-entry handling to tests for the concrete cache implementation.

📋 Findings (6)

RESTRICT

1. [Functional.Check] src/caches/typings.test.ts:424 — Test name claims to verify that stale:true causes stale cache values to be returned before deletion, but the body only asserts that the LRUDiskCacheOptions object echoes back the literal values it was constructed with (options.stale === true, options.maxAge === 5000). No actual cache/LRU behavior is exercised since typings.ts only exports type declarations — this gives false confidence that stale-read behavior is covered.
   → Rename the test to reflect what is actually checked (e.g. 'should accept a stale boolean option'), or move real behavioral coverage of stale-read semantics to the test suite for the LRUDiskCache implementation itself.
2. [Functional.Check] src/caches/typings.test.ts:436 — Test name claims stale:false causes 'undefined for stale entries' to be returned, but the assertion only checks options.stale === false on the literal object passed in. No cache lookup or stale-entry logic exists in this file to substantiate the claim, since typings.ts is a type-only module.
   → Rename to describe the actual assertion, or relocate behavioral verification of stale-entry handling to tests for the concrete cache implementation.

SUGGEST

1. [Evolvability.SolutionApproach] src/caches/typings.test.ts:469 — The entire suite re-verifies structural conformance to interfaces (FetchResult, DiskStats, LRUStats, CumulativeStats, MultilayerStats, LRUDiskCacheOptions) that TypeScript already enforces at compile time; none of these tests exercise runtime logic since the imported module contains only type declarations. This duplicates the compiler's job as runtime assertions, adding maintenance cost (495 lines) without increasing real coverage of behavior.
   → Consider dropping structural-conformance-only tests for pure type files, or replace them with a lightweight compile-time check (e.g. a .ts fixture file that only needs to type-check) and reserve *.test.ts runtime suites for modules with actual logic.
2. [general.clarity] src/caches/typings.test.ts:6 — The file header states tests validate structures 'through type assertions and compile-time checks,' but the tests are plain Jest runtime assertions (expect(...).toBe(...)) on object literals, not compile-time checks. This is misleading about what the suite actually guards against (e.g. it will not fail if tsc strict checks are bypassed by the test transpiler).
   → Clarify the header comment to state that these are runtime shape/usage examples, not compile-time type tests, or add an explicit tsc --noEmit step if compile-time validation is actually intended.
3. [Evolvability.Textual] src/caches/typings.test.ts:404 — Test descriptions 'should handle stale:true to return stale values before deletion' and 'should handle stale:false to return undefined for stale entries' (lines ~404-421) assert runtime behavior that the test body never exercises — it only checks that a literal assigned to options.stale/options.maxAge equals itself. The names imply the cache actually returns stale values or undefined on expiry, which this type-only test cannot verify.
   → Rename these tests to reflect what's actually checked (e.g. 'should accept stale: true/false as a boolean option'), or move behavioral claims about stale-value handling to tests against the actual LRUDiskCache implementation.
4. [Evolvability.SolutionApproach] src/caches/typings.test.ts:1 — The entire suite only constructs object literals matching the typings.ts interfaces and asserts the field equals the value it was just assigned (e.g. expect(stats.hits).toBe(100) after { hits: 100 }). Since typings.ts contains only compile-time type declarations with no runtime logic, these assertions are tautological and add no regression protection beyond what tsc already guarantees at compile time.
   → Consider dropping runtime assertions for pure type files (a tsd/expectType-style compile check is sufficient), or redirect this test effort toward the cache implementations that actually consume these types (e.g. LRUDiskCache behavior for stale/maxAge).
