oh-my-codex v0.12.5

Team-runtime and multi-workflow state hardening, Windows reliability, tmux/shell stability, and HUD session anchoring

0.12.5 is a broad stability patch across 25 PRs and 74 files changed. It resolves a cluster of inter-related session-scoping, team startup/shutdown, Windows worker-path, and tmux cwd bugs that accumulated since 0.12.4, adds current-task baseline branch guardrails for team workers, and tightens multi-workflow state management.

Highlights

• Multi-skill planning state preserved — ralplan/ralph state no longer drops when a mixed-workflow prompt is re-routed mid-flight (#1471).
• Team startup recovery — workers that stall early during boot no longer hang the entire team launch sequence (#1444).
• Windows reliability — split-pane shutdown targeting, psmux launcher resolution, MCP orphan cleanup, and retired-config repair are all fixed (#1470, #1469, #1437, #1436).
• tmux/shell cwd correctness — detached tmux panes, worker shell launches, and Homebrew zsh paths now all honour the requested working directory (#1468, #1460, #1462).
• HUD and session anchoring — HUD state is now strictly scoped to the active OMX session; native session-id drift no longer hides transport failures (#1453, #1458).
• Ralph stop-hook session isolation — stop-hook leakage across sessions is eliminated (#1466).
• Current-task baseline guardrails — new per-task baseline branch tracking keeps team workers anchored to their correct starting commit (#1419).

What's Changed

Added

• Current-task baseline branch guardrails for team workers (PR #1419)
• Approved multi-workflow overlap support in canonical state (PR #1427)
• Windows ps fallback for notify hooks (PR #1457)

Fixed — Team startup / shutdown

• Stalled-worker startup no longer hangs team boot (PR #1444)
• Cross-session stale root team Stop blocking eliminated (PR #1451)
• Linux tmux startup handoff and shutdown-state persistence (PR #1438)
• session.json ownership and fallback semantics tightened (PR #1447)

Fixed — Multi-skill / workflow state

• Planning state preserved in mixed workflow prompt routing (PR #1471)
• Workflow handoff correctness and state-model documentation (PR #1442)
• Flaky hook and HUD state scope alignment (PR #1446)

Fixed — Windows

• Split-pane shutdown stale leader-pane targeting (PR #1470)
• Native psmux worker startup launcher resolution (PR #1469)
• MCP orphan cleanup on parent shutdown (PR #1437)
• Retired team MCP config repair on upgrade (PR #1436)

Fixed — tmux / macOS / shell

• Detached tmux launch cwd loss (PR #1468)
• Worker cwd preserved on supported shell launches (PR #1460)
• Homebrew zsh tmux pane shell normalization on macOS (PR #1462)
• tmux startup PID resolution and copy-mode cleanup hardening (PR #1459)

Fixed — HUD / session anchoring

• HUD state anchored to active OMX session scope (PR #1453)
• Native session-id drift no longer hides team transport failures (PR #1458)

Fixed — deep-interview

• Stop auto-continuation no longer fires during the deep-interview intent-first questioning phase; that phase is now treated as planning for stall detection (PR #1473, issue #1472)

Fixed — Explore harness

• omx explore now emits a clear actionable error when cargo is a rustup shim with no default toolchain, instead of surfacing the raw rustup message (src/cli/explore.ts)

Fixed — Hooks / auth / notify

• Ralph stop-hook leakage across sessions eliminated (PR #1466)
• Auto-nudge authorization leaks for read-only/planning flows (PR #1434)
• Notify hooks stay tracking live teams through coarse state drift (PR #1428)
• Launcher-backed MCP restart stalls now bounded (PR #1408)

Docs

• Removed stale prompts/ invocation guidance (PR #1417)
