v0.25.0

Features

• Gate ledger substrate (t635_1): Tasks can now carry named approval checkpoints ("gates") recorded in a durable ledger — the foundation for gate-aware dependency, archival, and resume behavior.
• Task-workflow checkpoint recording (t635_2): With the new record_gates profile option, the task workflow records its approval checkpoints (plan approved, risk evaluated, build verified, review approved, merge approved) as gate runs. Enabled by default on the fast profile.
• Dependency-unblock semantics (t635_3): A task's dependents are now released as soon as its integration gates pass, rather than waiting for the task to fully complete.
• Gate-guarded archival (t635_4): A task that declares gates won't archive until all of them pass, with an in-session "resolve now & archive" offer and an --ignore-gates escape hatch.
• Ledger-driven re-entry (t635_5): The task workflow is now re-entrant — picking up an in-flight task resumes it at the right point (planning, implementation, or post-implementation) based on its recorded checkpoints.
• Applink WebSocket listener (t822_7): Added the applink control plane — a paired, TLS-secured wss:// listener that lets the mobile companion app connect, plus a Devices screen for viewing and revoking paired devices.
• Shadow context fetch (t986_3): Added a helper that resolves a task's file and most-recent plan (and optionally sibling context) to feed the shadow companion.
• Shadow companion command (t986_4): Added /aitask-shadow, an advisory companion that reads a followed agent's terminal output to explain it, help answer a prompt, or critically challenge its plan.
• Minimonitor shadow trigger (t986_5): The minimonitor can now launch a shadow companion for the followed agent (the e key), with a configurable agent/model and same-window-vs-separate-window placement.

Bug Fixes

• Preserve local models on upgrade (t982): Upgrading now merges new seed models into your model configuration instead of overwriting it — local entries are kept and new ones appended.
• Monitor refresh benchmark (t984): Fixed the monitor-refresh benchmark to patch the current monitor internals instead of a removed symbol.
• Cross-repo deps in board detail (t990): The board detail view now shows cross-repo dependencies, and opening a linked cross-repo task renders its metadata and body correctly instead of raw YAML.
• Project resolver whitelist (t991): Whitelisted the project-resolver helper so code agents can resolve cross-repo project names without a permission prompt.
• Archived tasks in board dialogs (t992): Board relation dialogs (Depends / Verifies) now resolve and open archived tasks read-only instead of failing to find them.
• Narrow-pane sibling dialogs (t998): Fixed cramped rendering of the minimonitor's next-sibling dialogs in narrow panes — they now widen and stack their buttons vertically.

Enhancements

• Minimonitor shadow layout (t994): Improved the minimonitor shadow pane (placement and configurable width), reorganized the footer, added an r refresh binding, and wrapped the task description onto two lines.
• Trim kill-confirm dialog (t995): Trimmed the minimonitor's kill-confirmation dialog so it fits in narrow panes.
• Shadow startup greeting (t997): The shadow companion now greets you with its capabilities at startup and proactively surfaces relevant observations after each capture.

Improvements

• Extract monitor core (t822_6): Extracted a Textual-free headless monitor core module — the shared substrate for the monitor TUIs and the new applink listener (no user-visible behavior change).
• Brainstorm node detail panel (t983_1): Refactored the brainstorm node-detail view into a reusable panel widget.
• Brainstorm node-selection model (t983_2): Added a headless node-selection model (primary cursor + marked set) for the brainstorm TUI.
• Pane-keyed monitor state (t986_1): Re-keyed monitor state by pane so multiple agents per window — and shadow panes — are tracked and excluded correctly.

Tests

• Multi-session monitor test update (t999): Aligned the multi-session monitor test suite with the monitor_core package and the new shadow-target pane field.

Maintenance

• Stale test comment fix (t915): Fixed a stale comment in the skill-render test suite.
• Port shadow to Codex (t988): Ported the /aitask-shadow command to Codex CLI.
• Port shadow to OpenCode (t989): Ported the /aitask-shadow command to OpenCode.
