+## [0.9.1] - 2026-07-28
+
+### Added
+
+- Change status CLI: query and mutate workflow state locally (#43)
+- Emergent work spin-off (#9)
+- **Repo resolution is now explicit.** specsync resolves the target repository deterministically and always passes `--repo` to every `gh` invocation. Resolution order: `-repo` flag → `gh repo set-default` → `origin`. Fork-parent writes are refused by default; use `-repo` to override. Board resolution also gained a repository-local declaration: `openspec/specsync.yml` with `board: owner/number`. The `-project` flag and this config file are the only ways to set a board; the `SPECSYNC_PROJECT` env var is no longer used. (#76)
+- Added `specsync audit-tasks` to detect unchecked tasks where code exists, enforced via CI. Reconciled 47 changes — checked off done tasks, spun off follow-ups, fixed design docs that didn't match code. (#60)
+- Multi-provider sync (fan-out) (#24)
+- Auto-detect Beads provider (#62)
+- Claim work in flight so concurrent agents don't collide (#78)
+- Link existing issues by reference, without scaffolding specs (#18)
+- convergence check for 3-way board merge (#42) (#74) (04ea25a6)
+- linker cleanup — LinkerResult, slug-matching, dead code removal (#97) (079b9132)
+- add --worktree flag to pull — create or reuse worktree (#51) (#72) (18c09518)
+- add specsync validate command for change structure (#64) (#67) (22cfa581)
+- spec-issue-linker — pull integration, Linker context resolution, skill doc (#95) (47cedb84)
+- spec-issue-linker — Linker interface, resolvers, sync integration (8b752045)
+- stable task ID — position-based mapping for rewritten task detection (#65) (#73) (b542d927)
+- slug validation, archived priority support (#43) (#75) (f0d8d40e)

+### Changed

+- Work graph (#19)
+
+### Fixed

+- Add `specsync audit` — a read-only command that cross-references archived OpenSpec changes against GitHub PRs to find archived changes whose PR was never merged. Also add a new `shipped` stage that represents the final step in the lifecycle: the PR has landed. (#59)

+# Linker cleanup: LinkerResult, slug-matching, dead code removal
+
+## Why
+
+The linker from the spec-issue-linker change needed hardening and cleanup after
+the initial merge. The branch resolver resolved all changes to the same issue
+when syncing multiple changes, MarkerResolver was too expensive, and
+ExternalResolver was dead placeholder code.
+
+## What
+
+- Add `LinkerResult` struct with `Source` field (e.g. "branch", "cache") for
+  dry-run visibility.
+- Fix BranchResolver slug-matching: `feat/42-my-change` only resolves when
+  syncing `my-change`, preventing all-changes-to-same-issue.
+- Remove MarkerResolver (API call per change, never needed in practice).
+- Remove ExternalResolver (dead placeholder code).
+- Simplify Pull to use BranchResolver directly instead of the full Linker chain.
+
+## Release note
+
+Linker resolves issue refs with source visibility (branch, cache) and slug-aware
+branch matching to prevent cross-change resolution.

+# Tasks: Linker cleanup
+
+## 1. LinkerResult with Source
+
+- [x] 1.1 Add `LinkerResult` struct with `Ref` and `Source` fields
+- [x] 1.2 Update `Linker` interface to return `*LinkerResult`
+
+## 2. BranchResolver slug-matching
+
+- [x] 2.1 Capture slug from branch name (`feat/42-slug` → slug = "slug")
+- [x] 2.2 Verify slug matches `changeDir` when resolving for a specific change
+
+## 3. Dead code removal
+
+- [x] 3.1 Remove MarkerResolver
+- [x] 3.2 Remove ExternalResolver
+- [x] 3.3 Update tests to remove dead resolver tests
+
+## 4. Pull simplification
+
+- [x] 4.1 Pull uses BranchResolver directly (no Linker chain)
+- [x] 4.2 Remove Linker field from PullOptions
+
+## 5. BuildSyncLinker
+
+- [x] 5.1 Only BranchResolver in sync linker (cache handled per-provider)
+
+## 6. Tests
+
+- [x] 6.1 All linker tests use `*LinkerResult`
+- [x] 6.2 Full test suite passes
