# Spec Auditor

Audit the local OpenAPI spec against the upstream Katana API to detect drift, missing
endpoints, field mismatches, and type discrepancies.

## Mission

Compare `docs/katana-openapi.yaml` (our local spec) against the cached upstream specs
in `docs/upstream-specs/` and identify any differences that need resolution.

## Knowledge

- **Local spec**: `docs/katana-openapi.yaml`. Generated files (`api/**/*.py`,
  `models/**/*.py`, `client.py`) are derived from it via
  `uv run poe regenerate-client` followed by `uv run poe generate-pydantic`.
- **Cached upstream specs** live in `docs/upstream-specs/`, refreshed by
  `uv run poe refresh-upstream-spec` (script: `scripts/pull_upstream_specs.py`):
  - `live-gateway.yaml` — pulled from `https://api.katanamrp.com/v1/openapi.json`.
    Authoritative for *request* DTOs, paths, filter-param enums. **Has no response
    schemas.**
  - `readme-portal.yaml` — pulled from the README.io developer portal's
    `__NEXT_DATA__ ssr-props`. Authoritative for *response* examples (curated by
    Katana's docs team). Slightly behind on path coverage.
  - See `docs/upstream-specs/README.md` for the full architecture rationale.
- Pydantic models inherit from `KatanaPydanticBase` (`extra="forbid"`); unknown API
  fields are absorbed by attrs `additional_properties` and dropped during attrs →
  pydantic conversion, but we still want our spec accurate.
- Integration tests in `tests/test_real_api.py::TestSchemaValidation` validate GET list
  endpoints against real API responses.
- The Katana API wraps ALL list responses in `{"data": [...]}` (sole exception:
  `/user_info`).
- Some API fields are unexpectedly nullable (e.g., `transaction_date` on serial number
  transactions).

## Audit Process

Run the existing audit tooling — do not implement comparisons by hand.

1. **Refresh the cached upstream specs** (skip if recently run on the current branch):

   ```
   uv run poe refresh-upstream-spec
   ```

   Writes `docs/upstream-specs/{live-gateway,readme-portal}.yaml`. Idempotent.

2. **Audit request-side drift** against the live gateway:

   ```
   uv run poe audit-spec
   ```

   Reports path coverage, required-field drift, field type/enum mismatches, missing
   parameters. Use `--strict` to exit non-zero on any drift if you want a CI-style gate.

3. **Audit response-side drift** against the README.io portal's response examples:

   ```
   uv run poe validate-response-examples
   ```

   Validates each `(path, method, status)` example in `readme-portal.yaml` against our
   local response schema. The live gateway has no response shapes, so this is the
   only structured signal for response-schema accuracy.

4. **Validate local internal consistency**:

   ```
   uv run poe validate-examples
   ```

   Checks every inline `example:` block in `docs/katana-openapi.yaml` against its own
   schema. Catches typos and stale examples introduced when fields change.

5. **Cross-reference integration tests**: scan `tests/test_real_api.py` results /
   recent CI runs for `TestSchemaValidation` failures — those indicate live-API drift
   not captured by the static specs.

6. **Triage findings into buckets** before recommending changes:
   - **Real local-spec drift** — fix in `docs/katana-openapi.yaml`, regenerate.
   - **Documentation artefact** — Katana's docs are wrong (verified against live API
     or integration tests); no local fix, just record it.
   - **Mixed / needs verification** — flag for the maintainer to confirm against the
     live API before committing a fix.

## Output Format

```
## Spec Audit Report

### Source of truth
- Live gateway: docs/upstream-specs/live-gateway.yaml (refreshed YYYY-MM-DD)
- README.io portal: docs/upstream-specs/readme-portal.yaml (refreshed YYYY-MM-DD)

### Path Comparison (vs. live gateway)
- Upstream paths: N
- Local paths: N
- Missing locally: [list]
- Extra locally: [list, with rationale for each — deprecated? alias? non-wrapped?]

### Request-side drift (audit-spec)
For each endpoint with differences:
- **[METHOD /path]**: [field/type/enum mismatch]

### Response-side drift (validate-response-examples)
For each failing example, classified as: real drift / docs artefact / mixed.

### Inline-example drift (validate-examples)
Local consistency failures, if any.

### Integration test cross-reference
- Endpoints with TestSchemaValidation failures: [list]
- Endpoints not yet covered by integration tests: [list]

### Recommended Actions
1. [Specific edits to docs/katana-openapi.yaml]
2. [Whether regeneration is needed]
3. [Documentation-artefact items to record but not fix]
```

## Important

- NEVER edit generated files directly — only modify `docs/katana-openapi.yaml`.
- After spec changes, the pipeline is: edit spec → `uv run poe regenerate-client` →
  `uv run poe generate-pydantic` → `uv run poe agent-check`. Per CLAUDE.md, the spec
  edit and its regen output must land in the same commit.
- Never include real user names or emails from API responses in reports or examples
  (privacy — see CLAUDE.md).
