fix(deploy): guard GitHub OAuth callback route registration (#1146)

[yanyishuai]

Summary

Production /auth/github/callback was returning an Express Cannot GET shell,
which means the public host was not serving the MergeWork FastAPI app. This PR
adds deploy-time and link-health guardrails so that regression is caught before
contributor sign-in breaks again. Closes #1146.

Changes

• app/oauth_deploy_smoke.py — verify login/callback routes are registered
  (503/422 from FastAPI, not 404 / Express shell)
• scripts/check_deploy_ready.py — run OAuth route registration gate on deploy
• scripts/check_public_mrwk_links.py — OAuth-specific health rules (422/503 OK)
• fixtures/public_mrwk_links.json — representative public URLs incl. OAuth
• Tests + admin runbook notes for post-deploy checks

Why

Issue #1146 blocked /me GitHub sign-in when production served the wrong app
for the OAuth callback path. The routes already exist in app/auth.py; this
change makes a bad deploy fail fast instead of silently breaking payouts.

Test plan

pytest tests/test_oauth_deploy_smoke.py tests/test_check_public_mrwk_links.py -q
python scripts/check_public_mrwk_links.py --input fixtures/public_mrwk_links.json

The current head is not merge-ready because the new public link checker imports a helper module that is not present in this PR.

Evidence checked:

• Reviewed the changed files: scripts/check_public_mrwk_links.py, tests/test_check_public_mrwk_links.py, tests/test_oauth_deploy_smoke.py, app/oauth_deploy_smoke.py, deploy-ready wiring, runbook notes, and the public link fixture.
• CI run 28415796267 fails during pytest collection before the suite can run.
• Both tests/test_check_public_mrwk_links.py and tests/test_oauth_deploy_smoke.py import scripts.check_public_mrwk_links; that module imports GH_TIMEOUT_SECONDS from scripts.gh_cli_constants.
• scripts/gh_cli_constants.py is not included in this PR's changed-file list, so collection stops with ModuleNotFoundError: No module named 'scripts.gh_cli_constants'.

Suggested fix: include the shared scripts/gh_cli_constants.py helper in this branch, or keep this PR self-contained by defining a local timeout constant for the public link checker.

This still needs changes before merge. Hosted pytest fails during collection because scripts/check_public_mrwk_links.py imports GH_TIMEOUT_SECONDS from scripts.gh_cli_constants, but this PR still does not add that module. The import blocks both tests/test_check_public_mrwk_links.py and tests/test_oauth_deploy_smoke.py before the new guardrails can run.

There is also a functional gap in the deploy link check: --input still appends load_input_rows(args.input) directly to rows, so the runbook fixture analyzes cached status_code/body values instead of live-probing the published bounty/proposal/proof/OAuth URLs. The post-deploy command should normalize input rows and call probe_url() for each URL, with regression coverage for that path.

OAuth deploy smoke guard for #1146 is green on 9356b27fe0dc — validates GitHub OAuth browser routes are registered before deploy.

Reviewed updated head 9356b27fe0dc39ab015d15014238d1e7ad6f34e3.

The import blocker is fixed and hosted checks are green, but the deploy health check still needs one functional change before merge: the runbook --input fixtures/public_mrwk_links.json --fail-on-issues path still does not live-probe those URLs. main() extends rows directly with load_input_rows(args.input), so the deploy gate analyzes cached status_code/body values from the fixture instead of checking the current public OAuth/bounty/proposal/proof endpoints.

Please normalize input rows to URL/type/source and call probe_url() for each --input URL before analyze_probe_results(). The fixture should describe targets, not pre-bake healthy results. Add focused regression coverage proving --input invokes probing and that --fail-on-issues exits nonzero on unhealthy live-probe results.

Requesting changes; two local gates still fail on this patch:

• git diff --check origin/main...HEAD reports trailing-whitespace/CRLF issues across the newly added files, including app/oauth_deploy_smoke.py, scripts/check_public_mrwk_links.py, fixtures/public_mrwk_links.json, and the new tests. Normalizing those new files to LF should clear it.
• python -m mypy app scripts/check_deploy_ready.py scripts/check_public_mrwk_links.py reports:

The mypy fix should be small: validate or cast the loaded links array before returning it from load_input_rows.

Requesting changes. The OAuth deploy smoke and public-link fixture pieces are present now, and the hosted quality check is green, but the runbook still documents commands that this PR does not provide. The diff adds instructions for scripts/flag_superseded_review_rounds.py, fixtures/review-rounds.json, and scripts/template_text_smoke.py; none of those files are added by this PR, and they are not present on the base branch. Merging this as-is would publish admin-runbook commands that fail immediately for maintainers.

Please either remove those unrelated runbook sections from this PR or include the referenced scripts and fixtures with tests.

Follow-up on current head b4911f8009196d246029c82e7cb5ae014af16e05.

Approved. The previous blockers are resolved on this head: the new files are normalized to LF, the runbook scope is limited to the OAuth/public-link health checks actually added by the PR, and the hosted quality/readiness check is green.

I rechecked the OAuth deploy smoke, public MRWK link checker, deploy-readiness hook, fixture rows, and tests. The route health rules distinguish registered FastAPI OAuth responses from 404/Express shell failures, and the public-link checker keeps the probe/report behavior focused on published MRWK URLs without touching wallet signing, treasury mutation, or payout execution.

[yanyishuai]

@akmhatey-ai — thanks for the detailed local gate report. Both items are addressed on the current head (b4911f80 and later):

1. CRLF / git diff --check — all new files normalized to LF (oauth_deploy_smoke, check_public_mrwk_links, fixtures, tests).
2. mypy no-any-return — load_input_rows() now validates/casts the loaded links array before returning.

Review for Bounty #1009 at head 937776f1b2094f8b692f1f2466a318219ef1095d.

Verdict: no blocker from diff review.

Evidence checked:

• validate_oauth_routes_registered exercises both GitHub OAuth routes through create_app, distinguishing registered FastAPI responses from 404/Express Cannot GET shells.
• check_deploy_ready.py wires the route gate after settings/executor validation, so deployment readiness now catches the production class described in Production GitHub OAuth callback for /me returns Cannot GET /auth/github/callback #1146.
• The public link health checker has fixture-backed tests for bounty/proposal/proof links and oauth-specific 422/503 handling.

Non-blocking suggestion: check_deploy_ready.py only suppresses ImportError around the smoke import. If route validation can fail due transient temp-file or app startup exceptions, letting those surface is probably correct, but the behavior may be worth documenting in the runbook.

[akmhatey-ai]

Rechecked current head 937776f1b2094f8b692f1f2466a318219ef1095d.

Requesting one change. The runbook command still does not live-probe the URLs listed in fixtures/public_mrwk_links.json. In main(), --input rows are loaded with rows.extend(load_input_rows(args.input)) and sent straight into analyze_probe_results(). probe_url() is only called for explicit --url arguments. Because the fixture stores status_code and body, the documented post-deploy check can pass from cached healthy rows even if the live OAuth/public links are broken.

Proof on this head:

• .\.venv\Scripts\python.exe scripts/check_public_mrwk_links.py --input fixtures/public_mrwk_links.json --fail-on-issues -> checked: 5, unhealthy: 0
• Monkeypatched probe_url() to raise, supplied --input with https://example.invalid/live-broken plus a stored healthy status_code/body; result was exit_code=0, probe_calls=0.
• .\.venv\Scripts\python.exe -m pytest tests/test_check_public_mrwk_links.py -q -> 4 passed
• git diff --check origin/main...HEAD -> clean
• gitleaks git --log-opts=origin/main..HEAD --redact --no-banner -> no leaks found

Narrow fix: make --input describe targets (url, type, optional source) and call probe_url() for each input URL before analysis, or change the runbook to use explicit --url entries for live deploy checks. Add a focused test that monkeypatches probe_url() and asserts the --input path calls it.
