Closes #506.

Why: the live stack-state block listed every run directory individually — a 120-line wall of done (F=…) entries that buries the signal the onset greeting needs, and no age check on "solving" runs, so an eight-day-old zombie (no FINISHED marker) was reported to the user as "one run still solving".

The fix, in the plugin's runs builder:

  • Live runs (unfinished, younger than 12 h): one line each, with age.
  • Older unfinished runs: STALE — no FINISHED since <date> (probably dead, do not present as live).
  • Finished runs: exactly ONE backlog line — count, best F, latest run — with a pointer to the full history in the runs dir.

Version bumped 0.2.4 → 0.2.5 (shipped plugin content changes; keeps installed-vsix dir resolution unambiguous).

Verification: plugin suite 17/17 (3 new live-runs cases: fresh-live vs zombie, backlog collapse, empty), typecheck clean, extension suite 1209 passed / 5 skipped / 100 files.

Summary by CodeRabbit

  • Improvements

    • Live run status now clearly distinguishes active, stale, and finished runs.
    • Active runs display their age, while unfinished runs older than 12 hours are marked stale.
    • Finished runs are summarized in a compact backlog view with count, fidelity, and latest-run details.
    • Empty run histories are omitted for a cleaner display.
  • Release

    • Updated the extension to version 0.2.5.

The runs block listed every run dir individually: a 120-line wall of
finished entries burying the signal, and any run without FINISHED
reported as 'solving' with no age check — an Aug-14 zombie was
presented to the user as 'one run still solving'.

- live runs (unfinished, < 12h): one line each, with age
- older unfinished: STALE — no FINISHED since <date>, 'probably dead,
  do not present as live'
- finished: ONE backlog line (count · best F · latest) + pointer to
  the full history in the runs dir
- version 0.2.4 -> 0.2.5 (shipped plugin content changes; keeps
  installed-vsix dir resolution unambiguous)

Closes #506.

Review Change Stack

📝 Walkthrough

Walkthrough

The extension now classifies unfinished runs as live or stale, includes age data for live runs, and aggregates finished runs into one backlog summary. Tests cover these states and the package version is now 0.2.5.

Changes

Live-run reporting

Layer / File(s) Summary
Run classification and aggregation
packages/extension/opencode-plugin/stack_state.ts
The stack-state builder applies a 12-hour stale threshold, formats live-run age, parses fidelity values, and summarizes finished runs by count, best fidelity, and latest completion.
Reporting tests and extension version
packages/extension/test/stack_state.test.ts, packages/extension/package.json
Tests cover live, stale, finished, and empty run states. The test seam accepts a custom runs directory. The extension version changes from 0.2.4 to 0.2.5.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 923a6

In an edge case where finished runs have no fidelity data, the backlog summary can omit the required best-fidelity and latest-run fields. The change is otherwise mergeable, but the summary contract should be corrected or explicitly accepted by the owner.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Keep required backlog fields when fidelity is unavailable.

If every finished run lacks result.toml, Line 293 makes withF empty. Lines 297-298 then omit both best F and latest, although the backlog contract requires those fields. Always emit latest, and render an unavailable best fidelity as best F=—. Add a fixture where all finished runs have no fidelity.

Proposed fix
-        const withF = done.filter((d) => d.fidelity !== undefined);
         const latest = done[done.length - 1];
         const bits = [
           `${done.length} finished`,
-          best !== undefined ? `best F=${best.toFixed(6)}` : null,
-          withF.length > 0 ? `latest ${latest.name}${latest.fidelity !== undefined ? ` (F=${latest.fidelity.toFixed(6)})` : ""}` : null,
+          best !== undefined ? `best F=${best.toFixed(6)}` : "best F=—",
+          `latest ${latest.name}${latest.fidelity !== undefined ? ` (F=${latest.fidelity.toFixed(6)})` : ""}`,
         ].filter(Boolean);
