docs(TST-30): new finding — single shared Gitea runner is a CI throughput/availability bottleneck
Surfaced during TST-25 acceptance verification: all CI runs on one shared gitea-runner (maxParallel=1, co-located 10.100.0.35) interleaved with dohertj2/lmxopcua, and Gitea 1.26 has no run cancel/delete API, so queue latency is unbounded under cross-repo contention and the runner is a single point of failure. Design: add a second/labelled runner; document the no-cancel reality and the run-windev-ci.sh queue-bypass. Low/P2. Roll-ups updated.

| 2026-07-13 | TST-25/TST-26 → `In progress` (branch `fix/tst-25-windev-ci`). Added `scripts/ci/{windev-worker-ci.ps1,run-windev-ci.sh,windev.known_hosts}`, `windows-x86` (per-push) + `nightly-windev` (scheduled) jobs in `ci.yml`, and the TST-26 doc/comment fixes (GatewayTesting.md, Contracts.md, check-codegen.ps1). Mechanism hand-verified on windev: `build`→0, bogus-SHA→nonzero (lock released), `test`→356 passed/0 failed in ~50s (per-push stays `test`, no demotion), and run-windev-ci.sh SSH+EncodedCommand exit-code propagation confirmed. |

| 2026-07-13 | Operator bring-up complete: dedicated CI ed25519 key installed in windev `administrators_authorized_keys` (authorized into `dohertj2`, which owns the working MXAccess/toolchain env — a fresh OS account would break the build; the key is independently revocable), Gitea secrets `WINDEV_SSH_KEY`/`WINDEV_SSH_KNOWN_HOSTS` + variable `WINDEV_SSH_USER=dohertj2` stored, runner→`10.100.0.48:22` egress verified on the `traefik` net, issue-write confirmed. **TST-25/TST-26 → `Done`:** credentialed `windows-x86` ran GREEN on `d769244` (Gitea run #37) — Linux runner SSHed windev, checked out the SHA in `C:\build\mxaccessgw-ci` under lock, ran the x86 Worker build + `Worker.Tests`, exit 0; `nightly-windev` correctly skipped on the push event. Branch merged to `main`. Follow-ups (old tracker): revisit **TST-05** (scheduled live smoke — now covered by `nightly-windev`) and **TST-24** (client wire tests) which this unlocks. |

Also **deflaked** `SessionManagerTests` fail-fast timing assertions (absolute `<100ms` wall-clock bound flaked under CI load; now anchored to the configured timeout / dropped for the zero-timeout case). Checks passed: unreachable-host fast-fail (exit 255/15s), deliberate-red propagation (Worker.Tests failure → exit 1), lock concurrency (2nd run waits), no-key-in-logs (masked). Pending: forced-failure nightly issue. Merge target `df7e20d` verified GREEN via the local windev path (Worker build + 356 tests). |
