> Single source of truth for resuming work. Read this FIRST when starting a session.
|

> Update at the end of every work phase so the next `/clear` resumes in 1 read.

## ✅ Done (2026-10-03..08, all pushed on `scheduler-framework`)
|
||
|
||
- **HA fixes** (Gitea #338-#340): bug-1915 (a PreVote round is decided once; a leader promotes only with its own election's votes), bug-1919 (promotion fence released once a RECOVER_TRUNCATED node has caught up), bug-1920 (replicated WAL writes refused before this boot's `persist_recover`; catch-up streams from min(join position, standby report)).
|
||
- **bug-1914/1917/1918** (Gitea #341-#343): config-push barrier 2000 ms under the commit-wait admission reservation; `xce_ctx_reconnect` quiesces the old endpoint (follow-up `f26a2d45`: from its own task it skips the wait, and stale-generation tasks are dropped); refused inbound packets are no longer leaked.
|
||
- **bug-1736 exposure** (Gitea #344, `1cedd7f7`): capnp `Job.runUsage` carries the controller's run usage to the apiserver and into snapshots (checkpoints used to drop it); REST columns `max_mem`, `avg_mem`, `used_mem`, `cpu_time`, `peak_cpu`, `peak_cpu_time`, `peak_cpu_duration`, `mem_efficiency`, `avg_cpu_efficiency`, `peak_cpu_efficiency`; xcecli `-o` fields `MAX_MEM`, `AVG_MEM`, `MEM_EFFICIENCY`, `CPU_PEAK`, `CPU_PEAK_DURATION`, `CPU_EFFICIENCY`, `CPU_PEAK_EFFICIENCY` and an LSF-style usage block in `jobs list -l`.
|
||
- **Harness fake worker** (Gitea #345, #346): bug-1921 (handler notifications deferred to the delay-manager thread; re-join after a reconnect), bug-1922 (answers the worker-rejoin-resync job-state query).
|
||
- **Soak** (`5cf92335`): `wal-layout-check.py` gate before PASS (sequential/chaotic/truncated-fence) and the `--truncated-fence` mode (truncated boot -> refused promotion -> fence released -> leads).
|
||
- Verification across these: 127/127 suites; soaks sequential 4x20 + 50 + 20, chaotic 50, loaded 30 (40 spinners on 32 cores), truncated-fence -- all PASS; 80/80 live HA config pushes under load; live run-usage check (fake worker -> controller -> apiserver -> xcecli).

## 🚀 Next phase
|
||
|
||
**Goal:** _None active._ Pick from the open items below.
|
||
|
||
### Open items (not yet actioned)
|
||
- **Review + merge PR #347** (https://gitea.shenrs.eu/nexa/xce/pulls/347, `rshen:scheduler-framework` -> `nexa/xce` `develop`, the repo's first PR): 2,140 commits, fast-forward onto `develop`; most of the +2 M lines are vendored Go modules. `master` (`fdfc42f1`) is 2 commits ahead of `develop` and was not merged into the branch.
|
||
- **Checks needing a host with systemd/dbus** (this container has none): a running array element prints the right `XCE_JOBINDEX`; bug-1908's kept signal reaches a real (non-virtual) worker over IPC at RUNNING; real `xcecd` (cgroup-measured) run usage in `xcecli jobs list -l` end to end.
|
||
- **Specs awaiting the next phase:** design review -- `xce-node-manager`; requirements written -- `job-status-detail-display`, `scheduler-preemption`, `scheduler-sim-decision-trace`; initialized -- `commit-batch-window`, `resource-distribution-mapping`; brief -- `component-rejoin-resync`.
|
||
- **Roadmap backlog (briefs only):** application-profile → job-sandbox-execution → job-sandbox-multinode; job-time-window → job-dependency → job-dependency-insight; rbac-persistence; scheduler-alter-pend-reasons; controller-job-cleanup.
|
||
- Small, optional: the fake worker reports finished jobs as `unrecognized` in its resync answer (no finished-job retention); `--truncated-fence` is opt-in (could join a default soak, ~3 min).
|
||
|
||
### Files to create / edit
|
||
- _none pending_
|
||
|
||
### Open decisions
|
||
- **REST job output for jobs with a custom `out_file`/`err_file`**: the worker never writes those paths (always `/tmp/job_<id>_task<N>.out`), so since bug-1508 `GET /jobs/:id/output` for such a job returns a permission error from the worker. Either the apiserver's `resolveOutputPath()` (controllers/output.go) always targets the worker's own output file, or the worker starts honouring `out_file`. Waiting on the user.
|
||
- **Bug records not mirrored to Gitea:** ~400 older records plus bug-1885–bug-1908 (bug-1736 and bug-1914/1915/1917-1922 are mirrored). A sync without `--since`/`--ids` would create an issue for each. Default: leave them off Gitea.

|
||
## 📁 Active architecture
|
||
|
||
- **Stack:** Go API/CLI tier (`src/frontend/apiserver`) fronting C daemons (`src/controller`, `src/worker`, `src/scheduler`); Meson-based build via `src/tools/xce-build.sh`, hermetic nix dev shell.
|
||
- **Bug tracking:** `.wolf/bugs/*.md` (records) → `scripts/buglog.py` (CLI + checks) → `.wolf/buglog.json` (generated index) → `scripts/gitea-sync.py` (Gitea issues in `nexa/xce`).
|
||
- **Local-only, never committed:** `.claude/settings.json` (hook paths rewritten for this machine), `data/` (450 MB replays/logs).
