Two mirrored health-handler test suites (health-endpoints, health-probe-aliases)
probed the Caddy admin API with raw Origin-less native fetch. On the prod host
the adversarial cron runs the full jest suite every 30 min against a live Caddy
admin with enforce_origin: 12 journal 403 lines per run (~700/day of
'client is not allowed to access from origin' spam) while tests stayed green.
- Mirrors now call fetchT (byte-identical to src/app.js:930 probe) with fetchT
jest.spyOn-mocked at buildApp scope; caddyOk-configurable in both suites
- New guard test in utils-http-caddy-admin-origin.test.js: any __tests__ file
pairing a raw await-fetch with a Caddy-admin token (:2019|adminUrl|
CADDY_ADMIN) fails the suite — file-level pairing catches the historical
cross-line drift shape a call-window regex missed
- DC-087-ALLOW-RAW-FETCH comment escape hatch (raw-text marker, guard file
never self-exempts, skips logged to jest output)
Judge: GLM-5.3 cold read via delegate_task deleg_4d384dea (round 1 C -> round 2
B, zero blockers, polish folded). Verdict URN: urn:ump:azrv2xp72koiwi5r4yb6ureu4aqqloqq64sgmftsajh6ci2mzj2q
Mutation probes: historical drift reintroduction -> guard red; hatch marker ->
skipped+logged; restore -> 33/33. Full suite 2603/2603.
The caddy.ok check in /health/ready probed /config/ (51KB) and timed out
at 3s with "This operation was aborted" while Caddy admin was actually
healthy. Two underlying issues:
1. Native undici fetch() rejects connections to :2019 (Caddy admin). Use
fetchT() which falls back to raw http.request for the admin port.
2. /config/ is heavy and head-of-line blocks when /load is in flight.
Switch to /config/apps/http/servers/srv0/listen (9 bytes) and bump
timeout to 10s.
Verified on DNS2 2026-07-09: direct Caddy admin curl 200 in 3ms,
/health/ready was aborting at 3s. After fix: /health/ready caddy.ok
true in <100ms.
Caddyfile change (/etc/caddy/Caddyfile) added /dashcaddy-login to the
@needsAuth not path exclude so direct hits to the auto-login landing
page render the page instead of getting gate-redirected to a blank
302 — applied and reloaded via POST /load earlier this session.
The readiness probe was crashing with 'res.status is not a function' because
asyncHandler(async (req, res) => {...}, 'health-ready') was called directly,
but asyncHandler's signature is (logError, fn, context) — first arg is the
logger, not the handler. The fix uses boundAsyncHandler like all other routes
in the file do.
Added 8 unit tests for both /health/live and /health/ready:
- live always 200 (liveness ≠ readiness)
- ready returns 503 when config/services/docker fail
- no 'res.status is not a function' crash when dependencies fail
- all 4 check keys present in response
Also added MONITORING_PUBLIC env var (defaults true) and the new health
endpoints to PUBLIC_ROUTES so k8s probes can hit them without auth.
