 ## [Unreleased]
 
+## [2.13.1] - 2026-03-15
+
+### Fixed
+- Windows: multi-line commit messages in `mergeSliceToMilestone` broke shell parsing — switched to `execFileSync` with argument arrays
+- Windows: single-quoted git arguments and bash-only redirects in test files
+- Windows: worktree path normalization for `shouldUseWorktreeIsolation` and stale branch detection
+
+## [2.13.0] - 2026-03-15
+
+### Added
+- **Worktree isolation for auto-mode** — auto-mode creates isolated git worktrees per milestone, with `--no-ff` slice merges preserving commit history and squash merge to main on milestone completion
+- **Self-healing git repair** — automatic recovery from detached HEAD, stale locks, and orphaned worktrees
+- **Worktree-aware doctor** — git health diagnostics and worktree integrity checks
+- **Isolation preferences** — choose between worktree and branch isolation modes
+
+### Fixed
+- **Dispatch loop: parse cache stale data** — `dispatchNextUnit()` cleared path cache but not parse cache, allowing stale roadmap checkbox state to persist through doctor→dispatch transitions (#462)
+- **Dispatch loop: completion not persisted after agent session** — `handleAgentEnd()` now verifies artifacts and persists the completion key before re-entering the dispatch loop, preventing re-dispatch when `deriveState()` sees pre-merge branch state (#462)
+- **Dispatch loop: recovery counter reset without persistence** — loop-recovery and self-repair paths now persist completion keys and include a hard lifetime dispatch cap of 6 (#462, #463)
+- **Dispatch loop: non-execute-task units had no artifact verification** — `complete-slice`, `plan-slice`, and other unit types now verify artifacts on disk before bail-out (#465)
+- `@` file autocomplete debounced to prevent TUI freeze on large codebases (#452)
+- Guard against newer synced resources from future versions (#445)
+- Prevent `web_search` tool injection for non-Anthropic providers serving Claude models (#446)

 Each context file (full or draft) should be rich enough that a future agent encountering it fresh — with no memory of this conversation — can understand the intent, constraints, dependencies, what this milestone unlocks, and what "done" looks like.
 
+#### Milestone Gate Tracking (MANDATORY for multi-milestone)
+
+After EVERY Phase 3 gate decision, immediately write or update `.gsd/DISCUSSION-MANIFEST.json` with the cumulative state. This file is mechanically validated by the system before auto-mode starts — if gates are incomplete, auto-mode will NOT start.
+
+```json
+{
+  "primary": "M001",
+  "milestones": {
+    "M001": { "gate": "discussed", "context": "full" },
+    "M002": { "gate": "discussed", "context": "full" },

+  },
+  "total": 3,
+  "gates_completed": 3
+}
+```
+
+Write this file AFTER each gate decision, not just at the end. Update `gates_completed` incrementally. The system reads this file and BLOCKS auto-start if `gates_completed < total`.
+
+For single-milestone projects, do NOT write this file — it is only for multi-milestone discussions.
