## What
Adds a CI→OpenObserve metrics sidecar to the Playwright Regression
workflow. A new terminal job `report_to_openobserve` emits **one summary
JSON document per run** into the `ci_regression` OpenObserve stream, so
we can build reliability/performance dashboards.
This is the OSS half of a cross-repo change — the companion
o2-enterprise PR (`ci/o2-reporting`) instruments the DocGen and E2E
Council engines into `ci_docgen` / `ci_council`.
## How it works (safe by construction)
- **Non-invasive:** derives per-job timings + per-shard pass/fail from
the GitHub jobs API and the merged Playwright stats. The only edit to an
existing job is one additive `stats` output on
`merge_and_upload_reports`.
- **Cannot break CI:** the job is `continue-on-error` and posts through
`.github/scripts/o2-report.sh`, which always `exit 0`s (a missing secret
/ rotated passcode / unreachable host only warns).
- **No-ops until secrets exist** — safe to merge first.
## Metrics captured
Reliability (conclusion, shard pass/fail, test pass/fail/flaky/skipped),
duration & cost (wall-clock, `runner_seconds`, build time, per-shard
durations), throughput (trigger/actor/branch).
## Required secrets (this repo + o2-enterprise)
- `O2_REPORTING_INGEST_BASE` — `https://<host>/api/<org>`
- `O2_REPORTING_AUTH` — `base64("email:passcode")`
Full schema, dashboard SQL, and setup notes:
`.github/scripts/O2-REPORTING.md`.
## Validation
- YAML parse + jq unit tests + `actionlint` clean on the added code.
- Live **HTTP 200** test-ingest into the target instance, both via raw
curl and through the poster script.
