Ensures cache stays synchronized with dependency and status changes
by calling invalidateBlockedCache() at all mutation points (bd-5qim).
Cache invalidation points:
- AddDependency: when type is 'blocks' or 'parent-child'
- RemoveDependency: when removed dep was 'blocks' or 'parent-child'
- UpdateIssue: when status field changes
- CloseIssue: always (closed issues don't block)
The invalidation strategy is full cache rebuild on any change,
which is fast enough (<1ms for 10K issues) and keeps the logic simple.
Only 'blocks' and 'parent-child' dependency types affect blocking,
so 'relates-to' and other types skip invalidation.

Created internal/storage/sqlite/errors.go with:
- Sentinel errors: ErrNotFound, ErrInvalidID, ErrConflict, ErrCycle
- wrapDBError helpers that auto-convert sql.ErrNoRows to ErrNotFound
- Type-safe error checking with errors.Is() compatibility
Updated error handling across storage layer:
- dirty.go: Added context to error returns, converted sql.ErrNoRows checks
- util.go: Updated withTx to use wrapDBError
- batch_ops.go: Added context wrapping to batch operations
- dependencies.go: Wrapped errors from markIssuesDirtyTx calls
- ids.go: Added error wrapping for ID validation
Also restored sqlite.go that was accidentally deleted in previous commit.
All tests pass. Provides consistent error wrapping with operation context
for better debugging.

All changes follow Go best practices and maintain backward compatibility.
* Add feature request for .beads/README.md generation during init
Created bd-m7ge to automatically generate a promotional/documentation
README in the .beads directory when running 'bd init'. This will help
advertise Beads in open source repositories and provide quick reference
documentation for developers using AI coding agents.
The README will include:
- Brief explanation of Beads (AI-native issue tracking)
- Link to steveyegge/beads repository
- Quick reference of essential commands
- Compelling messaging to encourage adoption
* feat: add performance testing framework foundation
Implements foundation for comprehensive performance testing and user
diagnostics for beads databases at 10K-20K scale.
Components added:
- Fixture generator (internal/testutil/fixtures/) for realistic test data
* LargeSQLite/XLargeSQLite: 10K/20K issues with epic hierarchies
* LargeFromJSONL/XLargeFromJSONL: test JSONL import path
* Realistic cross-linked dependencies, labels, assignees
* Reproducible with seeded RNG
- User diagnostics (bd doctor --perf) for field performance data
* Collects platform info (OS, arch, Go/SQLite versions)
* Measures key operation timings (ready, list, show, search)
* Generates CPU profiles for bug reports
* Clean separation in cmd/bd/doctor/perf.go
Test data characteristics:
- 10% epics, 30% features, 60% tasks
- 4-level hierarchies (Epic → Feature → Task → Subtask)
- 20% cross-epic blocking dependencies
- Realistic status/priority/label distributions
Supports bd-l954 (Performance Testing Framework epic)
Closes bd-6ed8, bd-q59i
* perf: optimize GetReadyWork with compound index (20x speedup)
Add compound index on dependencies(depends_on_id, type, issue_id) to
eliminate performance bottleneck in GetReadyWork recursive CTE query.
Performance improvements (10K issue database):
- GetReadyWork: 752ms → 36.6ms (20.5x faster)
- Target: <50ms ✓ ACHIEVED
- 20K database: ~1500ms → 79.4ms (19x faster)
Benchmark infrastructure enhancements:
- Add dataset caching in /tmp/beads-bench-cache/ to avoid regenerating
10K-20K issues on every benchmark run (first run: ~2min, subsequent: <5s)
- Add progress logging during fixture generation (shows 10%, 20%... completion)
- Add database size logging (17.5 MB for 10K, 35.1 MB for 20K)
- Document rationale for only benchmarking large datasets (>10K issues)
- Add CPU/trace profiling with --profile flag for performance debugging
Schema changes:
- internal/storage/sqlite/schema.go: Add idx_dependencies_depends_on_type_issue
New files:
- internal/storage/sqlite/bench_helpers_test.go: Reusable benchmark setup with caching
- internal/storage/sqlite/sqlite_bench_test.go: Comprehensive benchmarks for critical operations
- Makefile: Convenient benchmark execution (make bench-quick, make bench)
Related:
- Resolves bd-5qim (optimize GetReadyWork performance)
- Builds on bd-6ed8 (fixture generator), bd-q59i (bd doctor --perf)
* perf: add WASM compilation cache to eliminate cold-start overhead
Configure wazero compilation cache for ncruces/go-sqlite3 to avoid
~220ms JIT compilation on every process start.
Cache configuration:
- Location: ~/.cache/beads/wasm/ (platform-specific via os.UserCacheDir)
- Automatic version management: wazero keys entries by its version
- Fallback: in-memory cache if directory creation fails
- No cleanup needed: old versions are harmless (~5-10MB each)
Performance impact:
- First run: ~220ms (populate cache)
- Subsequent runs: ~20ms (load from cache)
- Savings: ~200ms per cold start
Cache invalidation:
- Automatic when wazero version changes (upgrades use new cache dir)
- Manual cleanup: rm -rf ~/.cache/beads/wasm/ (safe to delete anytime)
This complements daemon mode:
- Daemon mode: eliminates startup cost by keeping process alive
- WASM cache: reduces startup cost for one-off commands or daemon restarts
Changes:
- internal/storage/sqlite/sqlite.go: Add init() with cache setup
* refactor: improve maintainability of performance testing code
Extract common patterns and eliminate duplication across benchmarks, fixture generation, and performance diagnostics. Replace magic numbers with explicit configuration to improve readability and make it easier to tune test parameters.
* docs: clarify profiling behavior and add missing documentation
Add explanatory comments for profiling setup to clarify why --profile
forces direct mode (captures actual database operations instead of RPC
overhead) and document the stopCPUProfile function's role in flushing
profile data to disk. Also fix gosec G104 linter warning by explicitly
ignoring Close() error during cleanup.
* fix: prevent bench-quick from running indefinitely
Added //go:build bench tags and skipped timeout-prone benchmarks to
prevent make bench-quick from running for hours.
Changes:
- Add //go:build bench tag to cycle_bench_test.go and compact_bench_test.go
- Skip Dense graph benchmarks (documented to timeout >120s)
- Fix compact benchmark prefix: bd- → bd (validation expects prefix without trailing dash)
Before: make bench-quick ran for 3.5+ hours (12,699s) before manual interrupt
After: make bench-quick completes in ~25 seconds
The Dense graph benchmarks are known to timeout and represent rare edge
cases that don't need optimization for typical workflows.
- Force single connection for all in-memory databases (including file::memory:)
- Close rows before executing statements in external_ref migration
- Prevents connection pool deadlock with MaxOpenConns(1)
- Fixes test failures in syncbranch_test.go
- Implement comprehensive schema probe in sqlite.New() that verifies all
expected tables and columns after migrations
- Add retry logic: if probe fails, retry migrations once
- Return clear fatal error with missing schema elements if probe still fails
- Enhance daemon version gating: refuse RPC if client has newer minor version
- Improve checkVersionMismatch messaging: verify schema before claiming upgrade
- Add schema compatibility check to bd doctor command
- Add comprehensive tests for schema probing
This prevents the silent migration failure bug where:
1. Migrations fail silently
2. Database queries fail with 'no such column' errors
3. Import logic misinterprets as 'not found' and tries INSERT
4. Results in cryptic UNIQUE constraint errors

Fixes panic during import when handleRename passes ExternalRef as *string.
The UpdateIssue function now accepts both string and *string for the
external_ref field to match the type definition in types.Issue.
**Problem:**
Closed issues were silently reopening during git sync/import operations.
When importing an issue update, the importer built an updates map with
status='closed' but NO closed_at timestamp. The UpdateIssue() function's
manageClosedAt() would only set closed_at when status was CHANGING to
closed, not when it was already closed. Result: closed_at got cleared,
effectively reopening issues.
**Root Cause:**
1. Importer built updates map without closed_at field (lines 443-451, 519-528)
2. closed_at was not in allowedUpdateFields whitelist
3. manageClosedAt() only managed closed_at for status TRANSITIONS
4. Import of already-closed issue → closed_at lost → issue reopens
**Impact:**
- WASM issues (bd-44d0, bd-8507, etc.) were closed on Nov 4 (commit 0df9144)
- They reopened as 'open' status during sync on Nov 5 (commit 8c9814a)
- Users had to repeatedly close the same issues
- Data integrity violation: status=closed with closed_at=NULL
**Fix:**
1. Add closed_at to allowedUpdateFields whitelist
2. Add closed_at to importer updates maps (both external_ref and ID paths)
3. Update manageClosedAt() to skip auto-management if closed_at explicitly provided
- Preserves import timestamps while maintaining auto-management for CLI operations
**Testing:**
- All internal/importer tests pass
- All internal/storage/sqlite tests pass
- Explicitly tests timestamp preservation in TestImportWithExternalRef
**Files Changed:**
- internal/importer/importer.go: Add closed_at to updates maps
- internal/storage/sqlite/sqlite.go: Allow closed_at updates, respect explicit values

Refactored resurrection functions to accept optional *sql.Conn parameter:
- Added tryResurrectParentWithConn() internal function
- Added tryResurrectParentChainWithConn() internal function
- Updated CreateIssue to use conn-based resurrection
- Updated EnsureIDs to use conn-based resurrection
This eliminates 'database is locked' errors when resurrection
happens inside an existing transaction.
Fixes bd-58c0
Phase 2 of fixing import failure on missing parent issues (bd-d19a).
Implemented:
- TryResurrectParent: searches JSONL history for deleted parents
- TryResurrectParentChain: recursively resurrects entire parent chains
- Creates tombstones (status=closed) to preserve hierarchical structure
- Modified EnsureIDs and CreateIssue to call resurrection before validation
When importing a child issue with missing parent:
1. Searches .beads/issues.jsonl for parent in git history
2. If found, creates tombstone with status=closed
3. Preserves original title and metadata
4. Appends original description to tombstone
5. Copies dependencies if targets exist
This allows imports to proceed even when parents were deleted,
enabling multi-repo workflows and normal database hygiene operations.
Part of bd-d19a (fix import failure on missing parents).

The previous code had two bugs:
1. Double 'file:' prefix when path was ':memory:'
2. Two '?' separators instead of proper '?...&...' syntax
This caused SQLite errors: 'no such cache mode: shared?_pragma=...'
Fixed by:
- Building connStr directly for :memory: case with proper syntax
- Using '&' to chain query parameters
- Handling filepath.Abs() only for real files, not :memory:

- Removed SyncAllCounters() and all call sites (already no-op with hash IDs)
- Removed AllocateNextID() and getNextIDForPrefix() - sequential ID generation
- Removed collision remapping logic in internal/storage/sqlite/collision.go
- Removed rename collision handling in internal/importer/importer.go
- Removed branch-merge example (collision resolution no longer needed)
- Updated EXTENDING.md to remove counter sync examples
These were all deprecated code paths for sequential IDs that are obsolete
with hash-based IDs. Hash ID collisions are handled by extending the hash,
not by remapping to new sequential IDs.
- Removed nextSequentialID() and getIDMode() functions
- Removed issue_counters table from schema
- Made SyncAllCounters() a no-op for backward compatibility
- Simplified ID generation to hash-only (adaptive length)
- Removed id_mode config setting
- Removed sequential ID tests and migration code
- Updated CONFIG.md and AGENTS.md to remove sequential ID references
Follow-up bd-2a70 will remove obsolete test files and renumber command.
- Start with 4-char IDs for small databases (0-500 issues)
- Scale to 5-char at 500-1500 issues, 6-char at 1500+
- Configurable via max_collision_prob, min/max_hash_length
- Birthday paradox math ensures collision probability stays under threshold
- Comprehensive tests and documentation
- Collision calculator tool for analysis
Also filed bd-aa744b to remove sequential ID code path.
- Changed generateHashID to start with 6 chars (3 bytes), expand to 7/8 on collision
- Updated both CreateIssue and CreateIssues (batch) to use progressive length fallback
- Updated tests to accept 9-11 char IDs (bd- + 6-8 hex chars)
- All new issues now generate with shorter, more readable IDs
- Existing 8-char IDs preserved (no migration needed)

- Add id_mode config (sequential|hash), defaults to sequential
- Update CreateIssue/CreateIssues to check id_mode and generate appropriate IDs
- Implement lazy counter initialization from existing issues
- Update migrate --to-hash-ids to set id_mode=hash after migration
- Fix hash ID tests to set id_mode=hash
- Fix renumber test to use explicit IDs
- All 183 test packages pass
This makes hash IDs backward-compatible opt-in rather than forced default.
- Add GetNextChildID to storage interface for generating child IDs
- Implement in SQLiteStorage with atomic counter using child_counters table
- Implement in MemoryStorage with in-memory counter
- Add --parent flag to bd create command
- Support hierarchical IDs (bd-a3f8e9.1, bd-a3f8e9.1.5) in CreateIssue
- Validate parent exists when creating hierarchical issues
- Enforce max depth of 3 levels
- Update ID validation to accept hierarchical IDs with dots
- Add comprehensive tests for child ID generation
- Manual testing confirms: sequential children, nested hierarchies, depth enforcement
- Add AllocateNextID() public method to SQLiteStorage for cross-package ID allocation
- Enhance handleRename() to handle collision during rename with retry logic
- Fix stale ID map issue by removing deleted IDs from dbByID after rename
- Update edge case tests to use convergence rounds consistently
- All N-way collision tests now pass (TestFiveCloneCollision, TestEdgeCases)
After 2 weeks of collision/stale-data fixes, reviewed all changes to identify
spurious code that is no longer needed after content-hash resolution was implemented.
**Removed:**
1. countReferences() function from collision.go (lines 274-328)
- Was used for reference-count based collision scoring
- Completely unused after switching to content-hash based resolution (commit 2e87329)
- Still exists in duplicates.go for deduplication (different use case)
2. ReferenceScore field from CollisionDetail struct
- Marked as DEPRECATED but never removed
- No longer used by ScoreCollisions() which now uses content hashing
3. TestCountReferences and TestCountReferencesWordBoundary tests
- Tested the now-deleted countReferences() function
- No longer relevant
**Fixed:**
- Updated CheckpointWAL comments to remove misleading "staleness detection" claim
- Staleness detection uses metadata (last_import_time), NOT file mtime
- CheckpointWAL is still valuable for data persistence and WAL size reduction
- Comments now accurately reflect actual benefits
**Verified:**
- All tests pass (internal/storage/sqlite)
- Content-hash collision resolution still works correctly
- No behavioral changes, just cleanup

Critical fix for silent data corruption where database created 173
duplicate issues with wrong prefix (beads- instead of bd-).
Root cause: When issue_prefix config was missing, CreateIssue fell
back to deriving prefix from database filename (beads.db → 'beads'),
while auto-import imported bd- issues from git with SkipPrefixValidation.
This created duplicates.
Changes:
1. Removed derivePrefixFromPath() - never derive prefix from filename
2. CreateIssue/CreateIssues now REJECT if issue_prefix config missing
- Fail-fast with clear error message
3. Auto-import now SETS issue_prefix from first imported issue if missing
- Handles fresh clone scenario safely
4. Added newTestStore() helper that sets issue_prefix for tests
5. Updated test setup in multiple files to prevent test failures
