* 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)

Use flush-only workflow when no git remote is configured
Detects local-only repos (no git remote) and provides appropriate instructions:
- bd sync --flush-only instead of full git workflow
- Clear note about local-only storage
- Prevents confusing git errors for non-git users
Stop existing daemons before binary replacement during install
Prevents file lock race condition by gracefully stopping bd daemons
before replacing the binary. Safe for fresh installs (skips if bd not found).
Fix git hooks failing when daemon is running
Git hooks were calling bd sync without --no-daemon, causing inline import to fail
with 'no database store available' because daemon mode only initializes daemonClient.
Fix: Add --no-daemon to all bd sync calls in git hooks to ensure direct mode.
Add project_id filter for Linear sync
When linear.project_id is configured, bd linear sync will only fetch issues
belonging to that project instead of all team issues.
Closes#937
In contributor mode (bd init --contributor), .beads/ is excluded in
.git/info/exclude to prevent committing upstream issue databases.
However, this exclusion applies to ALL worktrees, including the sync
worktree where .beads/ must be committed.
The fix adds -f flag to git add in commitInWorktree() to force-add
files even when gitignored. This follows the existing pattern in
beads where -f is used for worktree operations (git worktree add -f).
Fixes: bd sync failing with "git add failed in worktree: exit status 1"

Adds --dry-run flag that shows what would be created without actually
creating the issue. Useful for scripting and validation.
- Shows preview in human-readable format by default
- Outputs full issue JSON with --json flag (empty ID, not placeholder string)
- Skips all side effects (hooks, labels, dependencies)
- Works with --rig/--prefix flags (shows target rig)
- Errors gracefully with --file flag (not supported)
- Includes event fields when --type=event
- Add Option 3 to local-install step: build from source with macOS codesigning
- Clarify run-bump-script step: bump-version.sh is the authority for release mechanics
- Document --all flag includes --install --mcp-local --restart-daemons
- Add reference to ./scripts/bump-version.sh --help
When bd gate check encounters a gh:run gate with a non-numeric await_id
(workflow name hint like release.yml), it now auto-discovers the run ID:
- Queries GitHub directly with gh run list --workflow=X
- Takes the most recent run (deterministic: newest-first from API)
- Updates the gates await_id and proceeds with status check
This is ZFC-compliant: most recent run of workflow X is purely mechanical,
no heuristic scoring. Agents no longer need to run bd gate discover manually.
