Instead, a new `zap-authenticated-scan` job in `ci-quality.yml` runs +the authenticated scan against an ephemeral instance spun up inside the job +itself: fresh migrated SQLite DB, `runserver` bound to `0.0.0.0:8000`, scan +account seeded via a new idempotent management command +(`core/management/commands/seed_zap_scan_user.py`, mirroring the +`get_or_create`/`update_or_create` pattern in `seed_markets.py`). Credentials +(`ZAP_AUTH_USERNAME`/`ZAP_AUTH_PASSWORD`) are fixed CI-only literals defined +inline in the workflow — not a GitHub secret, since the DB is a throwaway +SQLite file destroyed at job end. + +`.zap/prei-auth-context.xml` defines form-based auth against +`/accounts/login/`, with logged-in/out indicator regexes (presence/absence of +`/accounts/logout/` and the password field) and a `` entry. The +credential is embedded as a base64 `username=...&password=...` blob directly +in the committed XML, rather than injected via a `-P username=... -P +password=...` CLI flag as originally sketched — `zap-full-scan.py` doesn't +expose a documented flag for that. This is acceptable because the credential +is non-secret: CI-only, throwaway-DB-scoped, with no access to anything real. + +The job runs `zap-full-scan.py -a -n /zap/wrk/.zap/prei-auth-context.xml -U +zap-ci-scan-only` and is a required check in `pr-gates-pass`, so it runs +pre-merge on every PR — a stronger "shift security left" posture than the +existing unauthenticated scan, which only runs post-deployment. +`post-deployment.yml`'s scan is left unchanged (defense in depth: one +authenticated pre-merge scan, one unauthenticated scan of the real artifact). + +Scope decision recorded in `docs/KNOWN_LIMITATIONS.md` LIMIT-22. + +### C-4: Flaky test detection, ledger, and quarantine + +`pytest.ini`'s `addopts` gains `--report-log=.pytest-report.jsonl`, provided +by the `pytest-reportlog` plugin (not built into pytest core — this was a +wrong assumption in the original plan, corrected during implementation once +`--report-log` failed with "unrecognized arguments"). With +`pytest-rerunfailures` already wired (`--reruns 1 --reruns-delay 5`), a +rerun-then-pass test shows up in the report log as two `"call"`-phase +reports for the same nodeid: an intermediate `"rerun"` outcome followed by a +final `"passed"` outcome. + +`.github/scripts/flaky_report.py` parses that JSONL file and detects exactly +that signature (`find_flaky_nodeids`). Two modes: + +- `--mode report`: prints a markdown summary (also appended to + `$GITHUB_STEP_SUMMARY` when set) without touching the ledger. Runs in + `ci-quality.yml`'s `tests-unit`/`tests-integration`/`tests-e2e` jobs on + every PR — visibility without any write contention between concurrent PR + runs or fork-PR permission issues. +- `--mode write`: same summary, plus updates `docs/quality/flaky_tests.json` + (nodeid → `count`, `first_seen`, `last_seen`, `quarantined`) and, once a + nodeid's cumulative count reaches the threshold (default 3), adds it to + `tests/.flaky_quarantine.txt`. Runs only from `docker-publish.yml`'s + `live-test` job (push-to-`main` only) — the single writer for the shared + ledger, avoiding merge conflicts between concurrent PRs. + +Because `live-test`'s BDD suite runs inside a Docker container (`docker exec +... pytest tests_bdd/`), the report log is written to `/app/.pytest-report.jsonl` +inside the container (picked up automatically from `pytest.ini`'s `addopts`, +since the image includes it) and copied out via `docker cp` before the +container is torn down. If the ledger or quarantine file changed, the job +bot-commits as `github-actions[bot]` with `chore(ci): update flaky test +ledger [skip ci]` and pushes directly to `main` (the job's `permissions` gains +`contents: write` for this). + +A new root `conftest.py` hook, `pytest_collection_modifyitems`, reads +`tests/.flaky_quarantine.txt` (if present) and marks matching nodeids +`pytest.mark.xfail(strict=False)` at collection time — quarantined tests keep +running and reporting on every run, but a known-flaky test can never fail the +build while it's being fixed. Verified end-to-end with a throwaway +deliberately-failing test converting to `1 xfailed`. + +### Residual gap + +The `docker-publish.yml` bot-commit step only runs on push-to-`main`, so it +can't be exercised from a PR branch.

The local duplicate `cap_rate()` was deleted; the module now +imports `cap_rate`/`cash_on_cash`/`to_decimal` from `investor_app.finance.utils` +directly. `cash_on_cash_yield()` keeps its distinct name and semantics +(all-cash acquisition yield: NOI over price+rehab, no debt service netted +out) but delegates its division through the canonical `cash_on_cash()` instead +of reimplementing `/` locally. The remaining composition helpers +(`gross_potential_rent`, `effective_gross_income`, `total_operating_expenses`, +`net_operating_income`, `max_allowable_offer`) converted their arithmetic to +`Decimal` via the reused `to_decimal()` helper; `solve_underwriting()` uses +`.quantize()` instead of `round()` for the final output. + +`orchestrator.py`'s `UnderwritingInput` construction boundary (`price * 0.012`/ +`price * 0.004` tax/insurance defaults) was wrapped in `Decimal("0.012")`/ +`Decimal("0.004")` arithmetic against a `to_decimal(canonical.price or 0.0)`- +coerced price, reusing `to_decimal()` rather than reinventing coercion. + +**Two non-obvious risks found during implementation:** +- `pytest.approx()` compared against a `Decimal` actual is + fragile, not uniformly broken — it silently short-circuits via exact + equality for representable values but raises `TypeError` on near-matches + (`abs(expected - actual)` can't mix `float` and `Decimal`).
