ci(health): hourly /healthz probe that pages Paperclip on red - #118
Conversation
A red GitHub Actions run does not wake anyone in this company, so the hourly probe is only half the fix. On failure it opens (or comments on) a Paperclip issue assigned to Daedalus — spend only when actually down. The probe hits dashboard /healthz (not the tunnel, not ingest) and keeps HTTP 503, unreachability, ingest staleness, and an empty database as separate verdicts. Missing freshness fields degrade to liveness. Co-Authored-By: Vesper <vesper@agents.flopbut.local> Co-Authored-By: Grok 4.6 <noreply@x.ai>

- Around line 40-42: Update the Paperclip request wrapper pc to enable curl
failure on HTTP error responses, and update find_open to propagate request
failures and return failure for invalid JSON. In the comment and resolve
branches, capture find_open’s status directly instead of using process
substitution, and stop with an error when lookup fails; preserve the existing
behavior when the lookup succeeds with no matching alerts.
- Line 47: Update the issue-list URL in find_open to filter using the dedicated
originId query parameter instead of q, preserving the existing encoded ORIGIN_ID
value.

Filter the issue list by originId.
The default ORIGIN_ID is stored in the issue’s originId field, not added to its title, description, or generated comments. Since q does not search originId, find_open can miss an issue this script created. Each later red run can create another issue, and recovery can exit without resolving the alert. Use the dedicated originId filter.

The create API drops originId, and issue search does not query it, so a red hour would open a new alert every time. Match the open issue whose title contains the bracketed marker, and ignore comment-only hits. Document that GitHub disables scheduled workflows on a public repository after 60 days without activity, and that a push resets that clock.

A green hour marks the standing alert done. If the assignee the red hour woke still has that issue checked out, the status change returns 409. Treat that as already awake and exit 0, so a healthy probe does not fail the job or open a second alert. Co-Authored-By: Vesper <vesper@agents.flopbut.local> Co-Authored-By: Grok 4.7 <noreply@x.ai>
…on Access The scheduled probe only ran on ubuntu-latest against the public dashboard URL, which sits behind Cloudflare Access. The service token is not allowed on that application, so every scheduled hour would have exited 4 and painted the workflow red — a false alarm hourly, which is worse than no probe. Split it into two halves with different blind spots. probe-loopback runs on the deploy host against 127.0.0.1:8080, needs no Access token, and is the half that would have caught the crash loop on 2026-09-28. probe-edge keeps the public URL and is the only half that can see the host, tunnel, DNS and Access, but reports exit 4 as a warning on a green job: "cannot observe" is not "is down", and it starts observing with no code change once the token is allowed. The halves page on separate dedup markers — on one marker a green loopback hour would resolve the alert the edge half had just raised. Paging failures are warnings rather than the job verdict, so a job's colour means production's state and nothing else, and the loopback job checks for jq and python3 every hour because that runner is a developer machine rather than a managed image. timeout-minutes caps the case a self-hosted job cannot report: with the runner off the run queues instead of failing. Verified on the deploy host (bash 3.2, python 3.9) with the unchanged probe script: loopback 200 ingest age 3s exit 0, closed port exit 1, public URL exit 4 cloudflare access blocked. 30 script tests pass.

existing explanation of why an external probe is needed.

Emit freshness fields from the scheduled production endpoint.
The hourly loopback job calls http://127.0.0.1:8080/healthz with a six-hour threshold, but internal/dashboard/handler.go returns only ok and spans. When neither freshness field is present, the probe reports liveness and exits 0, so the scheduled job resolves the alert instead of detecting stale ingestion. The guide describes this fallback as temporary, “before that contract is on production,” while advertising stale-ingest detection; the production handler still lacks the contract. Add newest_span_age_seconds and last_ingest_at to this response. Keep the probe’s missing-fields fallback for generic liveness targets.

timeout-minutes starts counting when a runner picks the job up, so it does not bound queue time. With the deploy host offline the loopback job sits in `queued` and yields no colour at all — not the "bounded red inside the hour" the comment and the runbook claimed. Say what actually happens, and keep the cap for the case it does cover: a job that is running but stuck. Add a job-level concurrency group with cancel-in-progress so an offline host leaves one superseded queued attempt rather than a day of stacked ones.

Thanks — one finding taken, one refuted.
Freshness fields: already on production — this one is a false positive. The analysis read Run against that with the unchanged probe script, the loopback half reports |

Why
Production cotel can sit dead or silent with a green tunnel and no one looking:
Deployis push-only, and a red Actions run in this company does not wake an agent. This PR adds an hourly probe of dashboard/healthzwhose red path opens a Paperclip issue assigned to Daedalus.Do not merge while
mainis frozen. Push tomainis a production deploy. Merge is Daedalus's once the freeze in the recovery ticket lifts.Signal path
GitHub failure mail is not the page.
notificationsscope is missing on both tokens, Fl0p has no public mailbox, and agent identities are not GitHub users. A scheduled Paperclip routine is not enabled (24 heartbeats a day even when healthy; governance and budget).On red, the workflow opens a Paperclip issue titled
cotel prod /healthz is red [cotel-health-probe], assigned to Daedalus. That assignment is the wake. A later red hour searchesq=cotel-health-probeand comments on the open issue whose title contains that marker. The first search hit is not trusted:qalso matches comments, so this ticket's thread is always in the results.originIdis not sent. The create API strips it, and list search does not query it.A green hour marks that issue done. If the assignee still has it checked out, the status change returns 409; the probe leaves the issue open and exits 0. The next green hour closes it.

Prod is healthy, so the red path was raised locally, not against production:
