## Goal

Establish explicit spec-to-test traceability for all 38 behavioral scenarios in `tests/docs/` spec files by creating named test functions in `tests/inc/` whose names match the spec scenario identifiers. Currently, 47 existing test files exercise the covered behaviors but without named linkage — a compliance audit cannot confirm which test proves which scenario without manually grepping all 47 files; the spec files are structurally orphaned from the test suite. Named functions (`test_in_01`, `test_ap_01`, etc.) make the linkage auditable in CI output and maintainable when spec scenarios change. Where an existing test already validates the behavior, the named function may delegate or assert the same condition — no duplicate logic required. Observable outcome: 38 named test functions in `tests/inc/` (one per scenario ID), all spec files promoted to ✅, `w3 .test l::3` green with zero new failures. Proven by `grep -r "fn test_in_\|fn test_ap_\|fn test_ft_\|fn test_pt_" tests/inc/ | wc -l` → ≥ 38.

## In Scope

- `tests/inc/` — 5 new test modules with 38 named functions, one per scenario ID
- `tests/docs/invariant/001_thin_client_principle.md` scenarios IN-01..IN-06
- `tests/docs/invariant/002_testing_standards.md` scenarios IN-07..IN-12
- `tests/docs/api/001_endpoint_coverage.md` scenarios AP-01..AP-12
- `tests/docs/feature/001_enterprise_reliability.md` scenarios FT-01..FT-08
- `tests/docs/pattern/001_module_organization.md` scenarios PT-01..PT-06
- Delegation to existing tests where behavior is already validated — thin wrappers acceptable, no duplication required
- Updating Status column from ⏳ to ✅ in each spec file as scenarios are implemented
- Updating `tests/inc/mod.rs` to include new test modules

## Out of Scope

- `tests/docs/operation/001_secret_loading.md` scenarios OP-01..OP-15 — separate operation test task
- Performance benchmarks — separate bench task
- Cross-crate test coverage — api_claude scope only
- New test infrastructure beyond test functions — no new harnesses
- Duplicating test logic that already exists — delegation and thin wrappers are the preferred form

## Requirements

- All work must adhere to applicable rulebooks (`kbase .rulebooks`)
- Integration tests: `#![cfg(feature = "integration")]` gate; real credentials via `from_workspace()` or `from_env()`; load with `.expect("...")`, never `if let Ok`
- Pattern/structural tests may be purely compile-time or static analysis (grep-based); no mocking
- No new mocks, fake keys, or hardcoded responses anywhere
- All functions under 50 lines; 2-space indent; `mod private { }` pattern per module organization pattern

## Work Procedure

Execute in order. Do not skip or reorder steps.

1. **Read rulebooks** — `kbase .rulebooks`; note constraints on test file structure, feature gating, credential loading.
2. **Write Test Matrix** — populate every row below before opening any test file.
3. **Write failing tests** — for each spec scenario, write the test body and confirm it fails (or compile-errors) before implementing. If a test passes trivially, it is wrong.
4. **Implement** — write minimum test code to make tests pass against real API or via structural checks.
5. **Green state** — `w3 .test l::3` must pass with zero failures and zero warnings.
6. **Update spec files** — change ⏳ → ✅ in each spec file's Overview Table for every implemented scenario.
7. **Submit for Validation** — trigger SUBMIT transition (⏳ → 🔍).
8. **Update task state** — on validation pass, set ✅ in `task/readme.md` and move file to `task/completed/`.

## Test Matrix

*(Required — write before writing any test code.)*

| # | Input Scenario | Config Under Test | Expected Behavior |
|---|---------------|-------------------|-------------------|
| T01 | IN-01: Client::new() — zero enterprise features | Default client, no enterprise config | No retry, no cache, no rate limit; raw API path only |
| T02 | IN-02: No auto-retry without RetryConfig | Client, no retry config; API returns error | Error returned immediately; exactly one HTTP request |

| T19 | AP-07: create_message_stream() only under streaming | streaming feature enabled | Method present with feature; absent (compile error) without |
| T20 | AP-08: create_embedding() returns NotImplemented | embeddings feature | Returns Err(NotImplemented); no HTTP request made |

| T26 | FT-02: EnterpriseConfigBuilder requires explicit construction | All enterprise activation paths | No path activates enterprise without explicit builder call |
| T27 | FT-03: conservative() sets 3 retry attempts | retry-logic feature enabled | EnterpriseConfigBuilder::conservative().build() → max_attempts == 3 |

| T29 | FT-05: aggressive() sets 10 retry attempts | retry-logic feature enabled | EnterpriseConfigBuilder::aggressive().build() → max_attempts == 10 |
| T30 | FT-06: Enterprise modules compile only under their flag | One feature flag disabled | Corresponding module absent; its types not in public API |
| T31 | FT-07: Each enterprise module is independently gated | Any feature flag combo | Enabling one does not force another; disabling one does not break others |
| T32 | FT-08: EnterpriseConfigBuilder rejects invalid config | max_attempts=0 or zero-capacity | Returns Err with descriptive message; no panic |
| T33 | PT-01: lib.rs uses mod_interface! layer declarations | src/lib.rs | All modules as `layer` entries; no bare `mod module;` outside mod_interface! |

| T36 | PT-04: No private.rs or private/ in src/ | Entire src/ tree | No file named private.rs; no directory named private/ under src/ |
| T37 | PT-05: Optional modules use #[cfg(feature)] on layer line | src/lib.rs layer declarations | Each optional layer carries #[cfg(feature = "...")]; always-on have none |
| T38 | PT-06: exposed use visible externally; orphan use is not | Module's mod_interface! block | `exposed use` types accessible from outside; orphan `use` types not |

## History

*(append-only — newest entry last; never edit or remove past entries)*

- **2026-06-13** `CREATED` — Task filed by doc normalization session. Goal: implement all 30 spec scenarios from tests/docs/ as runnable tests in tests/inc/.
- **2026-06-13** `VERIFY FAIL` — MAAV returned FAIL on Dim 2 (Motivated used circular spec-status logic) and Dim 3 (YAGNI: 47 existing tests already cover behaviors; named functions without linkage rationale are redundant). Task revised: Goal rewritten to traceability rationale; In Scope updated to allow delegation to existing tests; Out of Scope extended to prohibit logic duplication.
- **2026-06-13** `VERIFY PASS` — MAAV (4 subagents) all PASS. Dim 1: In/Out Scope mutually exclusive and consistent with Goal. Dim 2: Motivated passes — concrete audit gap (0 of 438 existing test functions reference any spec ID; auditor must grep 47 files manually). Dim 3 (adversarial): YAGNI PASS — grep confirmed 0 spec-ID references in all test files; 30 scenarios all ⏳. Dim 4: Work Procedure, Test Matrix (T01–T30), Acceptance Criteria, Measurements all executable. State → 🎯 Verified.
- **2026-06-13** `CORRECTION` — Consistency audit revealed task used wrong scenario IDs and counts. Actual spec files use: TC-01..TC-06 (6), TS-01..TS-06 (6), AP-01..AP-12 (12), FT-01..FT-08 (8), PT-01..PT-06 (6) = 38 total. Original task said TC/TST/EP/ER/MO prefixes (wrong) and 30 scenarios (wrong). Also fixed: invariant spec files had IN- prefix collision (both used IN-; resolved to TC- and TS-). OP Out of Scope corrected: OP-01..OP-15 (was OP-01..OP-13). Task state remains 🎯 Verified — correction is factual, not scope-changing.
- **2026-06-13** `CORRECTION` — T07 test matrix entry updated: old text referenced file-level `#![cfg(feature = "integration")]` gate. Hygiene session corrected invariant 002_testing_standards.md to mandate function-level `#[cfg]` immediately before each integration test (not file-level). T07 rewritten to match. No scope change; task state remains 🎯 Verified.
- **2026-06-13** `COMPLETED` — All 38 test functions implemented across 5 new test modules (`thin_client_principle_test.rs`, `testing_standards_test.rs`, `endpoint_coverage_test.rs`, `enterprise_reliability_test.rs`, `module_organization_test.rs`). All 30 non-integration tests pass; integration tests (AP-01..AP-07, TC-04) fail loudly without credentials as required by TS-02. Self-match fixes applied to TS-03..TS-06 using `format!()` split patterns; PT-05 false positive fixed with adjacent-line check. All 38 spec scenarios promoted ⏳ → ✅.
