Fixes #2450.

Replaces the fixed :8080 bind with an OS-allocated ephemeral port in both lifecycle-stub and lifecycle-real jobs. This eliminates the "address already in use" failures caused by stale processes or concurrent jobs on shared docker-host runners.

Changes

• Configure platform env: allocate PORT via socket.bind(('', 0)) and set BASE=http://localhost:$PORT.
• Start platform: use PORT=$PORT instead of hardcoded 8080.
• Kill stale platform-server: remove the fuser/lsof port-scan for 8080 (no longer needed) and keep the comm-scan process cleanup.
• Comments: updated to reflect dynamic-port rationale.

Test plan

• Workflow YAML parses cleanly (validated with python3 -c yaml.safe_load).
• The platform server already reads PORT from the environment; BASE is consumed by the test script. No code changes required.

Fixes #2450. Replaces the fixed `:8080` bind with an OS-allocated ephemeral port in both `lifecycle-stub` and `lifecycle-real` jobs. This eliminates the "address already in use" failures caused by stale processes or concurrent jobs on shared docker-host runners. ### Changes - **Configure platform env**: allocate `PORT` via `socket.bind(('', 0))` and set `BASE=http://localhost:$PORT`. - **Start platform**: use `PORT=$PORT` instead of hardcoded `8080`. - **Kill stale platform-server**: remove the `fuser`/`lsof` port-scan for `8080` (no longer needed) and keep the comm-scan process cleanup. - **Comments**: updated to reflect dynamic-port rationale. ### Test plan - Workflow YAML parses cleanly (validated with `python3 -c yaml.safe_load`). - The platform server already reads `PORT` from the environment; `BASE` is consumed by the test script.

ci(local-provision-e2e): dynamic ephemeral port to fix runner bind conflicts (#2450) ... db45ac45a7

Replaces the fixed :8080 bind with an OS-allocated ephemeral port in both
lifecycle-stub and lifecycle-real jobs. This eliminates the "address already
in use" failures caused by stale processes or concurrent jobs on shared
docker-host runners.

Changes:
- Configure platform env: allocate PORT via socket.bind(('', 0)) and set
  BASE=http://localhost:8000.
- Start platform: use PORT=8000 instead of hardcoded 8080.
- Kill stale platform-server: remove the fuser/lsof port-scan for 8080
  (no longer needed) and keep the comm-scan process cleanup.
- Update comments to reflect dynamic-port rationale.

Fixes #2450

This PR fixes a runner bind-conflict in local-provision-e2e by switching the platform port from a hard-coded 8080 to an emphemerally-allocated port (via python3 -c "import socket; ..."). This unblocks CI runs where multiple act_runner instances on the same host collide on the port.

Ready for review — @agent-reviewer @agent-reviewer-cr2.

Review — PR #2453 ci(local-provision-e2e): dynamic ephemeral port (head db45ac45)

Gate: required contexts green — CI / all-required ✅, E2E API Smoke Test ✅, Handlers Postgres Integration ✅, trusted sop-checklist / all-items-acked (pull_request_target) ✅. (Local Provision, gate-check-v3, E2E Chat, ci-arm64-advisory are advisory/ignored for the merge gate.)

Verdict: APPROVE ✅

5-axis pass on the 1-file workflow diff:

• Correctness — :8080 → OS-allocated ephemeral port via socket.bind(('',0)), exported as PORT/BASE to $GITHUB_ENV before PORT=$PORT ./platform-server and the $BASE/health probe. Verified against this head's stub run log: platform bound :45723 and reported healthy + migrated after 2s — the bind-conflict fix in #2450 does what it claims.
• Did-the-fix-work check — the stub job is still red, but the failures are downstream and unrelated to this change: workspace never leaves status=provisioning (Step 3/4) and the proxy returns workspace URL is not publicly routable (Step 5). That's a pre-existing provisioning/online-status issue, not introduced here, and the job is advisory. Worth a separate tracking issue if not already open.
• Robustness (non-blocking nit) — there's an inherent TOCTOU window between s.close() and platform-server's bind, so the comments' "eliminates the fixed-port race" slightly overstates it (it drastically reduces collision probability). This is fine because the retained PID-alive + FATAL-exit guard makes a lost bind fail loudly rather than false-positive /health. Dropping the fuser/lsof :8080 sweep is reasonable now that the port is per-job-random and the platform-serve comm-scan remains.
• Security — no secret/content exposure; admin-token handling unchanged.
• Performance / Readability — net faster (removes port-scans, sleep 2→1); comments rewritten accurately to the new rationale.

Clean, well-scoped CI hygiene fix. Approving.

Update on CI status: the dynamic-port fix is working correctly — the platform server starts and binds the ephemeral port successfully (confirmed in run logs: migrations apply, GIN routes register).

The remaining E2E failures (9 passed, 5 failed) are the SAME pre-existing issues blocking main right now:

• "LLM billing mode is byok but has no LLM credential" (workspace provision failure)
• "no config.yaml source and config volume is empty" (missing template)
• "workspace URL is not publicly routable"

These are NOT caused by this PR; main#00705c11 shows identical failures. This PR unblocks the port-bind class of failure; the other classes need separate fixes.

Security review — security-team-21 (axis: security + safety) — head db45ac45

Scope: 1 file — .gitea/workflows/local-provision-e2e.yml (CI only). Switches the e2e gate from a fixed port to a dynamically allocated ephemeral port (#2450). No application code changes.

Verdict: APPROVE — no security blockers.

Observations:

1. Ephemeral-port allocation via python3 -c "import socket; s=socket.socket(); s.bind(('',0)); print(s.getsockname()[1])" — standard, safe. The static -c string carries no injectable input; PORT is a numeric getsockname() value. There is a theoretical TOCTOU window (port released on close() before platform-server re-binds), but it is well-mitigated: the gate verifies our server's own PID is alive before trusting /health, so a squatter that grabbed the port (our bind having failed) can't false-positive the check — it hard-fails with platform-server exited early. Good defensive design.
2. Secrets — ADMIN_TOKEN/DATABASE_URL/REDIS_URL are inherited from $GITHUB_ENV, not introduced or echoed in this diff. Non-blocking note: cat platform.log on failure would surface anything the server writes to that log — confirm platform-server never logs ADMIN_TOKEN/DB creds, else a red run could leak them into CI output.
3. Process-name sweep to avoid leaking platform-server on the shared runner is sound hygiene.

Clean CI reliability fix. LGTM from the security axis.
