 ## Local development
 
 - pyenv Python 3.12. `ruff check` + `ruff format --check` before pushing (hook-enforced).
-- Tests: `python -m pytest tests/ -q` (60 tests — classifier smoke test against a real
-  export + offline `cdk.assertions` synth checks + Block Kit builders). No AWS needed.
-- Smoke-test the classifier against a **real export** before declaring any
-  classification change done: `~/Downloads/_documents/Sheet1-1.xlsx`.
-- `cdk synth` must pass in CI before merge (**Docker required** — Lambda deps are
-  bundled for ARM64).
+- Tests: `python -m pytest tests/ -q` (~158 tests — classifier rule ladder + handler
+  transforms + Haiku fallback, Block Kit builders, the signature-verified Slack
+  interactions endpoint, slack-post orchestration, and offline `cdk.assertions` synth
+  checks). No AWS needed — external boundaries are monkeypatched. **Tests run in CI**
+  (`ci.yaml` sets `run-tests: true`); coverage is reported via `pytest-cov`
+  (`tests/requirements.txt`, ~94%, non-gating).
+- The classification quality gate (deterministic "Other" share) runs in CI against a
+  committed synthetic fixture `tests/fixtures/sample_export.csv`. Additionally,
+  smoke-test against the **real export** before declaring any classification change
+  done: `~/Downloads/_documents/Sheet1-1.xlsx` (skips automatically when absent).
+- `cdk synth` must pass in CI before merge (**Docker + QEMU** — Lambda deps are
+  bundled for ARM64; `ci.yaml` sets `enable-qemu: true`).
 
 ## Deployment
 
 CI/CD via the org reusable workflows (no manual prod deploys in steady state):
 
-- **CI** (`.github/workflows/ci.yaml`) → `ci-python-sam.yaml@main`: ruff + `cdk synth`. Runs on PRs into `main`.
+- **CI** (`.github/workflows/ci.yaml`) → `ci-python-sam.yaml@main`: ruff + `pytest` + `cdk synth` (QEMU-enabled). Runs on PRs into `main`.
 - **Deploy** (`.github/workflows/deploy.yaml`) → `cd-cdk.yaml@main`: OIDC assume-role, `cdk deploy --all`, single-flight concurrency. Runs on push to `main`.
