* feat(sync): implement pull-first synchronization strategy
- Add --pull-first flag and logic to sync command
- Introduce 3-way merge stub for issue synchronization
- Add concurrent edit tests for the pull-first flow
Ensures local changes are reconciled with remote updates before pushing to prevent data loss.
* feat(sync): implement 3-way merge and state tracking
- Implement 3-way merge algorithm for issue synchronization
- Add base state storage to track changes between syncs
- Add comprehensive tests for merge logic and persistence
Ensures data consistency and prevents data loss during concurrent
issue updates.
* feat(sync): implement field-level conflict merging
- Implement field-level merge logic for issue conflicts
- Add unit tests for field-level merge strategies
Reduces manual intervention by automatically resolving overlapping updates at the field level.
* refactor(sync): simplify sync flow by removing ZFC checks
The previous sync implementation relied on Zero-False-Convergence (ZFC)
staleness checks which are redundant following the transition to
structural 3-way merging. This legacy logic added complexity and
maintenance overhead without providing additional safety.
This commit introduces a streamlined sync pipeline:
- Remove ZFC staleness validation from primary sync flow
- Update safety documentation to reflect current merge strategy
- Eliminate deprecated unit tests associated with ZFC logic
These changes reduce codebase complexity while maintaining data
integrity through the robust structural 3-way merge implementation.
* feat(sync): default to pull-first sync workflow
- Set pull-first as the primary synchronization workflow
- Refactor core sync logic for better maintainability
- Update concurrent edit tests to validate 3-way merge logic
Reduces merge conflicts by ensuring local state is current before pushing changes.
* refactor(sync): clean up lint issues in merge code
- Remove unused error return from MergeIssues (never returned error)
- Use _ prefix for unused _base parameter in mergeFieldLevel
- Update callers to not expect error from MergeIssues
- Keep nolint:gosec for trusted internal file path
* test(sync): add mode compatibility and upgrade safety tests
Add tests addressing Steve's PR #918 review concerns:
- TestSyncBranchModeWithPullFirst: Verifies sync-branch config
storage and git branch creation work with pull-first
- TestExternalBeadsDirWithPullFirst: Verifies external BEADS_DIR
detection and pullFromExternalBeadsRepo
- TestUpgradeFromOldSync: Validates upgrade safety when
sync_base.jsonl doesn't exist (first sync after upgrade)
- TestMergeIssuesWithBaseState: Comprehensive 3-way merge cases
- TestLabelUnionMerge: Verifies labels use union (no data loss)
Key upgrade behavior validated:
- base=nil (no sync_base.jsonl) safely handles all cases
- Local-only issues kept (StrategyLocal)
- Remote-only issues kept (StrategyRemote)
- Overlapping issues merged (LWW scalars, union labels)
* fix(sync): report line numbers for malformed JSON
Problem:
- JSON decoding errors when loading sync base state lacked line numbers
- Difficult to identify location of syntax errors in large state files
Solution:
- Include line number reporting in JSON decoder errors during state loading
- Add regression tests for malformed sync base file scenarios
Impact:
- Users receive actionable feedback for corrupted state files
- Faster troubleshooting of manual configuration errors
* fix(sync): warn on large clock skew during sync
Problem:
- Unsynchronized clocks between systems could lead to silent merge errors
- No mechanism existed to alert users of significant timestamp drift
Solution:
- Implement clock skew detection during sync merge
- Log a warning when large timestamp differences are found
- Add comprehensive unit tests for skew reporting
Impact:
- Users are alerted to potential synchronization risks
- Easier debugging of time-related merge issues
* fix(sync): defer state update until remote push succeeds
Problem:
- Base state updated before confirming remote push completion
- Failed pushes resulted in inconsistent local state tracking
Solution:
- Defer base state update until after the remote push succeeds
Impact:
- Ensures local state accurately reflects remote repository status
- Prevents state desynchronization during network or push failures
* fix(sync): prevent concurrent sync operations
Problem:
- Multiple sync processes could run simultaneously
- Overlapping operations risk data corruption and race conditions
Solution:
- Implement file-based locking using gofrs/flock
- Add integration tests to verify locking behavior
Impact:
- Guarantees execution of a single sync process at a time
- Eliminates potential for data inconsistency during sync
* docs: document sync architecture and merge model
- Detail the 3-way merge model logic
- Describe the core synchronization architecture principles
* fix(lint): explicitly ignore lock.Unlock return value
errcheck linter flagged bare defer lock.Unlock() calls. Wrap in
anonymous function with explicit _ assignment to acknowledge
intentional ignore of unlock errors during cleanup.
* fix(lint): add sync_merge.go to G304 exclusions
The loadBaseState and saveBaseState functions use file paths derived
from trusted internal sources (beadsDir parameter from config). Add
to existing G304 exclusion list for safe JSONL file operations.
* feat(sync): integrate sync-branch into pull-first flow
When sync.branch is configured, doPullFirstSync now:
- Calls PullFromSyncBranch before merge
- Calls CommitToSyncBranch after export
This ensures sync-branch mode uses the correct branch for
pull/push operations.
* test(sync): add E2E tests for sync-branch and external BEADS_DIR
Adds comprehensive end-to-end tests:
- TestSyncBranchE2E: verifies pull→merge→commit flow with remote changes
- TestExternalBeadsDirE2E: verifies sync with separate beads repository
- TestExternalBeadsDirDetection: edge cases for repo detection
- TestCommitToExternalBeadsRepo: commit handling
* refactor(sync): remove unused rollbackJSONLFromGit
Function was defined but never called. Pull-first flow saves base
state after successful push, making this safety net unnecessary.
* test(sync): add export-only mode E2E test
Add TestExportOnlySync to cover --no-pull flag which was the only
untested sync mode. This completes full mode coverage:
- Normal (pull-first): sync_test.go, sync_merge_test.go
- Sync-branch: sync_modes_test.go:TestSyncBranchE2E (PR#918)
- External BEADS_DIR: sync_external_test.go (PR#918)
- From-main: sync_branch_priority_test.go
- Local-only: sync_local_only_test.go
- Export-only: sync_modes_test.go:TestExportOnlySync (this commit)

* fix(daemon): handle diverged sync branch with fetch-rebase-retry on push
When pushing to the sync branch, if the remote has newer commits that
the local worktree doesn't have, the push would fail with "fetch first"
error and the daemon would log the failure without recovery.
Bug scenario:
1. Clone A pushes commit X to sync branch
2. Clone B has local commit Y (not based on X)
3. Clone B's push fails with "fetch first" error
4. Without this fix: daemon logs failure and stops
5. With this fix: daemon fetches, rebases Y on X, and retries push
This fix adds fetch-rebase-retry logic to gitPushFromWorktree():
1. Detect push rejection due to remote having newer commits
2. Fetch the latest remote sync branch
3. Rebase local commits on top of remote
4. Retry the push
If rebase fails (e.g., due to conflicts), the rebase is aborted and
an error is returned with helpful context.
This allows multiple clones to push to the same sync branch without
manual intervention, as long as the changes don't conflict.
Adds integration test TestGitPushFromWorktree_FetchRebaseRetry that
verifies the fetch-rebase-retry behavior with diverged branches.
* fix: resolve all golangci-lint errors (cherry-pick from fix/linting-errors)
Cherry-picked linting fixes to ensure CI passes.

The TestSyncBranchCommitAndPush_WithPreCommitHook test needed fixes
to run correctly in isolation:
1. Set global dbPath variable so findJSONLPath() can locate the JSONL
file during sync operations. Without this, the test failed with
"JSONL path not found".
2. Add dummy git remote so hasGitRemote() returns true. The
syncBranchCommitAndPush function skips sync branch operations
when no remote is configured (local-only mode support).
3. Relax commit count assertion to check for "multiple commits"
rather than exact count of 4, since sync branch initialization
may add an extra commit depending on timing.
These changes ensure the regression test properly validates that
--no-verify bypasses pre-commit hooks in worktree commits.
Test verified:
- FAILS without --no-verify fix (confirms bug detection)
- PASSES with --no-verify fix (confirms fix works)
When pre-commit hooks are installed (via "bd hooks install"), daemon auto-sync
to sync branches fails with "git commit failed in worktree: exit status 1".
Root cause:
- gitCommitInWorktree() was missing --no-verify flag
- Pre-commit hook runs "bd sync --flush-only" which fails in worktree context
- Worktree has .beads directory, triggering hook execution
- Hook fails because bd cannot find proper database in worktree path
The fix adds --no-verify to git commit in gitCommitInWorktree(), matching
the existing implementation in internal/syncbranch/worktree.go line 684.
This is correct because:
- Worktree commits are internal to bd sync operations
- Running pre-commit hooks in worktree context is semantically wrong
- The library function already skips hooks for this reason
Includes regression test that:
- Creates a repo with sync branch configured
- Installs a failing pre-commit hook (simulating bd hook behavior)
- Verifies commits succeed because --no-verify bypasses the hook
- Tests multiple consecutive commits to ensure consistent behavior
Tested manually by:
1. Creating issue with "bd create" (triggers mutation event)
2. Verifying daemon logs show successful commit to sync branch
3. Confirming push to remote sync branch completes
Replaces manual working directory save/restore patterns
with Go's built-in `t.Chdir()` helper across 23 test files.
The manual pattern involved calling `os.Getwd()` to save
the original directory, using `defer os.Chdir(origWd)` for
restoration, and manually handling errors during directory
changes. This boilerplate has been replaced with single
`t.Chdir(path)` calls that handle cleanup automatically.
The `t.Chdir()` method automatically restores the working
directory when the test completes, eliminating the need for
manual defer statements and error handling.
Total:
~75 instances replaced (assuming Claude's math is right)

Fixes daemon and bd sync to honor BEADS_SYNC_BRANCH environment variable
as documented in PROTECTED_BRANCHES.md for CI/CD temporary overrides.
Changes:
- Updated internal/syncbranch.Get() to prioritize env var over DB config
- Both daemon sync and bd sync CLI now use syncbranch.Get()
- Added comprehensive tests for env var override behavior
- Validates branch names using git-style rules
This enables CI/CD workflows to override sync branch per-job without
mutating database config.

Complete implementation of signal-aware context propagation for graceful
cancellation across all commands and storage operations.
Key changes:
1. Signal-aware contexts (bd-rtp):
- Added rootCtx/rootCancel in main.go using signal.NotifyContext()
- Set up in PersistentPreRun, cancelled in PersistentPostRun
- Daemon uses same pattern in runDaemonLoop()
- Handles SIGINT/SIGTERM for graceful shutdown
2. Context propagation (bd-yb8):
- All commands now use rootCtx instead of context.Background()
- sqlite.New() receives context for cancellable operations
- Database operations respect context cancellation
- Storage layer propagates context through all queries
3. Cancellation tests (bd-2o2):
- Added import_cancellation_test.go with comprehensive tests
- Added export cancellation test in export_test.go
- Tests verify database integrity after cancellation
- All cancellation tests passing
Fixes applied during review:
- Fixed rootCtx lifecycle (removed premature defer from PersistentPreRun)
- Fixed test context contamination (reset rootCtx in test cleanup)
- Fixed export tests missing context setup
Impact:
- Pressing Ctrl+C during import/export now cancels gracefully
- No database corruption or hanging transactions
- Clean shutdown of all operations
Tested:
- go build ./cmd/bd ✓
- go test ./cmd/bd -run TestImportCancellation ✓
- go test ./cmd/bd -run TestExportCommand ✓
- Manual Ctrl+C testing verified
