Draft — item 12 (parallel e2e slots) plus the always-dumped lane logs from item 9.

What changed

• E2E_SLOT=: slot 0 is exactly today's lane (byte-identical rendered compose config, verified by diff); each n>0 gets its own compose project (noite-e2e-<n>), container/volume/network names, bucket and a non-overlapping port block (API/Caddy/store/fleet range). E2E_SLOT=auto takes the first free slot lock (1-8).
• Lock moves into the script: flock -o on /tmp/noite-e2e-lane-<slot>.lock with bounded wait (E2E_LOCK_WAIT, default 300 s). Old outer wrappers keep working on slot 0 (different file, no deadlock); that wrapper no longer excludes other slot-0 runs.
• E2E_KEEP=1 holds the slot via a keep sentinel until E2E_SLOT=<n> make e2e-down stops that slot's stack.
• Always-dump lane logs: lane-containers.log, lane-caddy-access.log, lane-stats.txt land in the report dir on every run (container log tail-limited: 100 lines green, 1000 red; Caddy access capped at 2 MB).
• Playwright auth/report/test-results dirs are slot-scoped so two lanes share one checkout; specs no longer hard-code lane ports/hosts (edge, app-lifecycle, env-telemetry, worker-errors follow the slot env).

Measured

• Slot-0 compose config diff vs main: identical (no output).
• Two-lane concurrency + CI results: see final report.

Summary by CodeRabbit

• Tests
  • End-to-end test runs can now use separate slots, allowing multiple lanes to run in parallel with isolated ports and test artifacts.
  • Select a slot to keep its services running for later use, or stop that slot explicitly. Slot locks wait for availability up to a configurable limit.
  • Test endpoints and artifact locations can be configured per lane, while existing defaults remain unchanged.
  • Run diagnostics now capture container logs and resource usage on success and failure, with additional host-process details on failure.

📝 Walkthrough

The E2E runner now supports parallel, slot-specific lanes with separate resources, directories, and locks. Playwright tests use configurable lane endpoints and paths. The runner also adds slot-specific teardown and retained-session handling, and saves run artifacts in the selected report directory.

Changes: Parallel E2E lanes

Layer / File(s)	Summary
Slot selection and resource configuration docker/e2e-local.sh, docker/compose.e2e.yaml, docker/compose.slot.yaml, docker/doctor.sh	The runner selects slots, acquires slot locks, and derives project, port, bucket, fleet, and directory settings. Compose and doctor configuration use the selected lane values.
Lane-specific Playwright paths and endpoints apps/noite/playwright.config.ts, apps/noite/e2e/*, apps/noite/.gitignore	Playwright state and artifacts can use lane-specific directories. E2E tests use configurable API and base URLs, and the invite lock uses the configured auth directory. The ignore rules cover numbered lane directories.
Lane teardown, retention, and artifacts docker/e2e-local.sh, Makefile, AGENTS.md	Teardown, retained-session handling, cleanup, and run artifacts are scoped to the selected slot. The Makefile adds e2e-down and includes numbered E2E projects in nuke; the instructions describe slot selection and release.

Merge Risk: 🟡 Moderate · up to b6285

The parallel-lane runner has two defects in its slot handling. A kept stack is not actually protected or released through its slot, and E2E_SLOT=auto can stop at the first busy slot instead of trying the next one. These affect local developer E2E workflows only, but they should be fixed before merge.

Parent: squashed and rebased onto ebaecbb, which brings in #81 (fleet peaks), #83, #89 and #90.

• Lane and doctor polish: snapshot wording, per-fleet peaks, D3 basis #81 conflicts:
  • hostile.spec.ts keeps main's version: Lane and doctor polish: snapshot wording, per-fleet peaks, D3 basis #81 removed the build-time fleet-peaks.json write, so the slot-scoped peaksFile is dropped too.
  • e2e-local.sh keeps Lane and doctor polish: snapshot wording, per-fleet peaks, D3 basis #81's runner-log peak aggregation, but writes fleet-peak-lines.txt, fleet-stop-lines.txt, fleet-peaks.json and lane-stats.txt into $E2E_REPORT_DIR. That's the slot's report dir; slot 0 is unchanged.
• CI: build lane image once, shard e2e lanes, nightly flake hunt #90 conflicts:
  • playwright.config.ts keeps CI: build lane image once, shard e2e lanes, nightly flake hunt #90's json reporter and shard. The html report and e2e-results.json both go to E2E_REPORT_DIR ?? playwright-report.
  • AGENTS.md combines both e2e bullets.
• Also: the CHANGELOG entry is now changelog.d/e2e-parallel-slots.md, and my make nuke fix is included (-@for, so one failing slot teardown can't abort the rest).
• Checks: bun run check, tsc, sh -n and check-changelog are clean.
• Review: the parent reviewed the slot and compose changes (compose.e2e.yaml env defaults keep slot 0 byte-identical; compose.slot.yaml only applies when the slot is above 0). Labelled security-reviewed; auto-merge on.

[ryuzdev]

Parent: rebased onto c2b4ab3 (#101). playwright.config.ts keeps #101's globalTimeout plus this PR's slot-scoped outputDir. In e2e-local.sh, a red lane still dumps the host process tree (#101) into $E2E_REPORT_DIR, alongside the always-dumped container logs. sh -n, check, tsc, check-tests and check-changelog are clean. The earlier red run (flake H, admin.spec:521) was the control-plane stall fixed in #100, not this diff. Re-labelled; auto-merge on.

- Around line 121-125: Update the `flock` invocation and status handling so lock
timeouts use a dedicated exit status and are captured without triggering `set
-e`. Print the “slot is busy” message only when that timeout status is returned,
while preserving the wrapped lane’s nonzero status without labeling it as a lock
timeout.
- Around line 444-445: Update the E2E_KEEP=1 branch in docker/e2e-local.sh to
write the background sleeper’s PID to KEEP_FILE before the branch exits, so
later runs and the down command can manage the kept stack.
- Around line 107-108: Update the flock invocations in the automatic-slot and
named-slot paths so their nonzero status is captured without triggering set -e
before error handling runs. Initialize rc before each invocation and assign the
command’s failure status to rc, preserving the existing slot-retry and
named-slot handling behavior.
