Use IMMEDIATE transactions with dedicated connections to fix race condition
where multiple processes creating issues concurrently caused "UNIQUE constraint
failed: issues.id" errors.
Key changes:
- Use BEGIN IMMEDIATE to acquire RESERVED lock early
- Use dedicated connection (sql.Conn) for transaction to ensure all operations
happen on same connection
- Increase busy_timeout from 10s to 30s for better parallel write handling
- Use context.Background() for ROLLBACK to ensure cleanup even if ctx cancelled
Added regression test TestParallelIssueCreation that creates 20 issues in
parallel and verifies no ID collisions occur.

When GetStatistics is called on an empty database, SQL SUM() returns NULL
which causes a scan error when converting to int. Wrap SUM expressions with
COALESCE to return 0 instead of NULL.
Add TestGetStatistics to verify both empty and populated database cases.

The ready_issues VIEW was using old logic that didn't propagate blocking
through parent-child hierarchies. This caused inconsistency with the
GetReadyWork() function for users querying via sqlite3 CLI.
Changes:
- Updated VIEW to use same recursive CTE as GetReadyWork()
- Added test to verify VIEW and function produce identical results
- No migration needed (CREATE VIEW IF NOT EXISTS handles recreation)
The VIEW is documented in WORKFLOW.md for direct SQL queries and is now
consistent with the function-based API.

The hierarchical blocking query recursively joins on dependencies with
a type filter. Without a composite index, SQLite must scan all
dependencies for a given depends_on_id and filter by type afterward.
With 10k+ issues and many dependencies per issue, this could cause
noticeable slowdowns in ready work calculations.
Changes:
- Added idx_dependencies_depends_on_type composite index to schema
- Added automatic migration for existing databases
- Index creation is silent and requires no user intervention
The recursive CTE now efficiently seeks (depends_on_id, type) pairs
directly instead of post-filtering.

When an epic is blocked, all its children should also be considered
blocked in the ready work calculation. Previously, only direct blocking
dependencies were checked, allowing children of blocked epics to appear
as ready work.
Implementation:
- Use recursive CTE to propagate blocking from parents to descendants
- Only 'parent-child' dependencies propagate blocking (not 'related')
- Changed NOT IN to NOT EXISTS for better NULL safety and performance
- Added depth limit of 50 to prevent pathological cases
Test coverage:
- TestParentBlockerBlocksChildren: Basic parent→child propagation
- TestGrandparentBlockerBlocksGrandchildren: Multi-level depth
- TestMultipleParentsOneBlocked: Child blocked if ANY parent blocked
- TestBlockerClosedUnblocksChildren: Dynamic unblocking works
- TestRelatedDoesNotPropagate: Only parent-child propagates

Move counter sync from import to CreateIssue to handle parallel issue creation.
This ensures the counter is always up-to-date before generating new IDs,
preventing collisions when multiple processes create issues concurrently.
Remove unused SyncCounterForPrefix method and its test.
When importing issues with explicit high IDs (e.g., bd-100), the
issue_counters table wasn't being updated. This caused the next
auto-generated issue to collide with existing IDs (bd-4 instead of bd-101).
Changes:
- Add SyncAllCounters() to scan all issues and update counters atomically
- Add SyncCounterForPrefix() for granular counter synchronization
- Call SyncAllCounters() in import command after creating issues
- Add comprehensive tests for counter sync functionality
- Update TestImportCounterSyncAfterHighID to verify fix
The fix uses a single efficient SQL query to prevent ID collisions
with subsequently auto-generated issues.
Replace the in-memory nextID counter with an atomic database-backed
counter using the issue_counters table. This fixes race conditions
when multiple processes create issues concurrently.
Changes:
- Add issue_counters table with atomic INSERT...ON CONFLICT pattern
- Remove in-memory nextID field and sync.Mutex from SQLiteStorage
- Implement getNextIDForPrefix() for atomic ID generation
- Update CreateIssue() to use database counter instead of memory
- Update RemapCollisions() to use database counter for collision resolution
- Clean up old planning and bug documentation files
Fixes the multi-process ID generation race condition tested in
cmd/bd/race_test.go.
Add TestMultiProcessIDGeneration to reproduce the bug where multiple
bd create processes fail with UNIQUE constraint errors when run
simultaneously. Each goroutine opens a separate database connection
to simulate independent processes.
Test currently fails with 17/20 processes getting UNIQUE constraint
errors, confirming the race condition in the in-memory ID counter.
Replace duplicated dirty-marking logic in AddDependency and
RemoveDependency with a new markIssuesDirtyTx helper function.
This improves code maintainability and ensures consistent behavior.
The Problem:
- AddDependency and RemoveDependency had ~20 lines of duplicated code
- Each manually prepared statements and marked issues dirty
- Violation of DRY principle
- Pattern was fragile if preparation failed
The Fix:
- Created markIssuesDirtyTx() helper in dirty.go
- Takes existing transaction and issue IDs
- Both functions now use: markIssuesDirtyTx(ctx, tx, []string{id1, id2})
- Reduced from 20 lines to 3 lines per function
Benefits:
- Eliminates code duplication (DRY)
- Single source of truth for transaction-based dirty marking
- More readable and maintainable
- Easier to modify behavior in future
- Consistent error messages
Changes:
- internal/storage/sqlite/dirty.go:129-154
* Add markIssuesDirtyTx() helper function
- internal/storage/sqlite/dependencies.go:115-117, 147-149
* Replace duplicated code with helper call in both functions
Testing:
- All existing tests pass ✓
- Verified both issues marked dirty with same timestamp ✓
- Dependency add/remove works correctly ✓
Impact:
- Cleaner, more maintainable codebase
- No functional changes, pure refactor
- Foundation for future improvements

SQLite's CAST to INTEGER never returns NULL - it returns 0 for
invalid strings. This meant the malformed ID detection query was
completely broken and never found any malformed IDs.
The Problem:
- Query used: CAST(suffix AS INTEGER) IS NULL
- SQLite behavior: CAST('abc' AS INTEGER) = 0 (not NULL!)
- Result: Malformed IDs were never detected
The Fix:
- Check if CAST returns 0 AND suffix doesn't start with '0'
- This catches non-numeric suffixes like 'abc', 'foo123'
- Avoids false positives on legitimate IDs like 'test-0', 'test-007'
Changes:
- internal/storage/sqlite/sqlite.go:126-131
* Updated malformed ID query logic
* Check: CAST = 0 AND first char != '0'
* Added third parameter for prefix (used 3 times now)
Testing:
- Created test DB with test-abc, test-1, test-foo123
- Warning correctly shows: [test-abc test-foo123] ✓
- Added test-0, test-007 (zero-prefixed IDs)
- No false positives ✓
- All existing tests pass ✓
Impact:
- Malformed IDs are now properly detected and warned about
- Helps maintain data quality
- Prevents confusion when auto-incrementing IDs

Fix critical TOCTOU bug where concurrent operations could lose dirty
issue tracking, causing data loss in incremental exports. Also fixes
bug where export with filters would incorrectly clear all dirty issues.
The Problem:
1. GetDirtyIssues() returns [bd-1, bd-2]
2. Concurrent CRUD marks bd-3 dirty
3. Export writes bd-1, bd-2
4. ClearDirtyIssues() deletes ALL (including bd-3)
5. Result: bd-3 never gets exported!
The Fix:
- Add ClearDirtyIssuesByID() that only clears specific issue IDs
- Track which issues were actually exported
- Clear only those specific IDs, not all dirty issues
- Fixes both race condition and filter export bug
Changes:
- internal/storage/sqlite/dirty.go:
* Add ClearDirtyIssuesByID() method
* Add warning to ClearDirtyIssues() about race condition
- internal/storage/storage.go:
* Add ClearDirtyIssuesByID to interface
- cmd/bd/main.go:
* Update auto-flush to use ClearDirtyIssuesByID()
- cmd/bd/export.go:
* Track exported issue IDs
* Use ClearDirtyIssuesByID() instead of ClearDirtyIssues()
Testing:
- Created test-1, test-2, test-3 (all dirty)
- Updated test-2 to in_progress
- Exported with --status open filter (exports only test-1, test-3)
- Verified only test-2 remains dirty ✓
- All existing tests pass ✓
Impact:
- Race condition eliminated - concurrent operations are safe
- Export with filters now works correctly

Implement automatic database migration to add the dirty_issues table
for existing databases that were created before the incremental export
feature (bd-39) was implemented.
Changes:
- Add migrateDirtyIssuesTable() function in sqlite.go
- Check for dirty_issues table existence on database initialization
- Create table and index if missing (silent migration)
- Call migration after schema initialization in New()
The migration:
- Queries sqlite_master to check if dirty_issues table exists
- If missing, creates the table with proper schema and index
- Happens automatically on first database access after upgrade
- No user intervention required
- Fails safely if table already exists (no-op)
Testing:
- Created test database without dirty_issues table
- Verified table was auto-created on first command
- Verified issue was properly marked dirty
- All existing tests pass
This makes the incremental export feature (bd-39) work seamlessly
with existing databases without requiring manual migration steps.

Optimize auto-flush by tracking which issues have changed instead of
exporting the entire database on every flush. For large projects with
1000+ issues, this provides significant performance improvements.
Changes:
- Add dirty_issues table to schema with issue_id and marked_at columns
- Implement dirty tracking functions in new dirty.go file:
* MarkIssueDirty() - Mark single issue as needing export
* MarkIssuesDirty() - Batch mark multiple issues efficiently
* GetDirtyIssues() - Query which issues need export
* ClearDirtyIssues() - Clear tracking after successful export
* GetDirtyIssueCount() - Monitor dirty issue count
- Update all CRUD operations to mark affected issues as dirty:
* CreateIssue, UpdateIssue, DeleteIssue
* AddDependency, RemoveDependency (marks both issues)
* AddLabel, RemoveLabel, AddEvent
- Modify export to support incremental mode:
* Add --incremental flag to export only dirty issues
* Used by auto-flush for performance
* Full export still available without flag
- Add Storage interface methods for dirty tracking
Performance impact: With incremental export, large databases only write
changed issues instead of regenerating entire JSONL file on every
auto-flush.

- Uses word-boundary regex (\b) to match exact IDs (bd-10 not bd-100)
New tests in collision_test.go:
- TestCountReferences: validates reference counting logic
- TestScoreCollisions: verifies scoring and sorting behavior
- TestCountReferencesWordBoundary: ensures exact ID matching
Reference score = text mentions (desc/design/notes/criteria) + deps

Critical bug fix: getNextID() was using alphabetical MAX instead of
numerical MAX, causing "bd-9" to be treated as max when "bd-10" existed.
