release: v0.28.5 — TP-181/183/184/185 bug fixes

[HenryLach]

Release v0.28.5

Bundles four bug fixes that landed since v0.28.4 (April 21).

Fixed

• TP-181 / fix: wire worker model from preferences through to lane runner #522 (@NerfEko) — taskRunner.worker.{model,thinking,tools} from preferences now actually flow through to spawned workers. Previously LaneRunnerConfig.workerModel was hardcoded to "" and the user's worker model config was silently ignored. Mirrors the existing reviewer pipeline (TP-160). +11 tests.

• TP-183 / Improve UX when Taskplane is not configured in current workspace #523 (@mwickens) — Pi no longer hard-blocks startup with a verbose red WORKSPACE_SETUP_REQUIRED error when run in directories without Taskplane configured. Soft-fails to a quiet status indicator (🔀 Orchestrator · disabled (no taskplane config in workspace)). All other WorkspaceConfigErrorCode values still surface loudly so real misconfigurations stay visible. +6 tests.

• TP-184 / Workers cannot call review_step / notify_supervisor / request_segment_expansion — missing from hardcoded tool allowlist #530 — Workers can now invoke review_step, notify_supervisor, escalate_to_supervisor, and request_segment_expansion. Engine-internal coordination tools were missing from the worker --tools allowlist, so plan/code/test reviews silently never fired at Review Level ≥ 1, supervisor steering replies were impossible, and multi-repo segment expansion was unreachable. New ENGINE_BRIDGE_TOOLS constant + buildWorkerToolsAllowlist() helper. +14 tests.

• TP-185 — Preflight pi check no longer misreports cold-start timeouts as "Pi not found". execCheck classifies failures by mode (not-found, timeout, exit-code, signal, unknown). Pi preflight uses 30s timeout (up from 10s) and retries once. Tailored failure hints. Backward compatible. +9 tests.

Validation

• ✅ Tests: 3452 passing / 0 failed / 1 skipped (full fast suite + integration)
• ✅ CLI smokes: taskplane help and taskplane doctor clean
• ✅ Package contents: 75 files, 634 KB packed, 2.5 MB unpacked (npm pack --dry-run)
• ✅ All four fixes confirmed live in global install via local-build verification
• ✅ TP-184 fix validated end-to-end via TP-114 regression run (4 review_step calls, 2 verdict files, Review Counter = 2)
• ✅ Sage code review on TP-184 (1 blocking finding remediated pre-merge: escalate_to_supervisor was missing) and TP-183 (no blockers; 1 optional improvement applied)

Test count growth

• v0.28.4: 3429 passing
• v0.28.5: 3452 passing (+23 across the four fixes)

What's NOT in this release (deferred)

• TP-186 candidates: static-assertion test for lane-runner.ts spawn-site wiring, migration of duplicated literals to a shared lightweight constants module, behavioral helper extraction for TP-183 testability, fix for taskplane doctor empty pi installed () display (pi prints version to stderr; getVersion only reads stdout)
• Two unrelated open external PRs (feat: support multi-repo orchestration in polyrepo workspaces #516 abandoned polyrepo, fix: resolve Pi CLI via process.argv[1] for Nix and non-standard installs #520 Nix CLI fix) and several open issues/discussions in the queue
