fix: Resolve race condition in parallel issue creation (bd-89)
Fixed UNIQUE constraint errors when creating multiple issues in parallel. Root cause: The previous two-step approach used INSERT OR IGNORE to pre-initialize counters, followed by an UPSERT to increment. Multiple concurrent transactions could all execute the INSERT OR IGNORE with the same initial value, causing them to generate duplicate IDs. Solution: Replaced with a single atomic UPSERT that: 1. Initializes counter from MAX(existing IDs) if needed 2. Updates counter to MAX(current, max existing) + 1 on conflict 3. Returns the final incremented value This ensures counters are correctly initialized from existing issues (fixing lazy init tests) while preventing race conditions through the BEGIN IMMEDIATE transaction serialization. Tested with 10 parallel processes - all succeeded with unique IDs. Also added comprehensive profiling test suite for import performance investigation (bd-199). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

{"id":"bd-197","title":"Add version mismatch warning for outdated binaries","description":"When bd detects that the database was created/modified by a newer version, warn the user that they may be running an outdated binary.\n\n**Problem:** Users may run old bd binaries without realizing it, leading to confusing behavior (e.g., missing features like auto-export).\n\n**Solution:** Store schema version or bd version in metadata table, check on startup, warn if mismatch.\n\n**Implementation:**\n1. Add `schema_version` or `bd_version` to metadata table during init\n2. Check version in PersistentPreRun (cmd/bd/main.go)\n3. Warn if binary version \u003c DB version\n4. Suggest: 'Your bd binary (v0.9.3) is older than this database (v0.9.5). Rebuild: go build -o bd ./cmd/bd'\n\n**Edge cases:**\n- Dev builds (show commit hash?)\n- Backwards compatibility (older DBs should work with newer binaries)\n- Don't warn on every command (maybe once per session?)\n\n**Related:** Fixes confusion from bd-182 (auto-export not working with old binary)","notes":"**Implementation Complete:**\n\n✅ Added version metadata storage during `bd init` (init.go:59-63)\n✅ Added `checkVersionMismatch()` function (main.go:301-345)\n✅ Integrated version check into PersistentPreRun (main.go:98-99)\n✅ Tested both scenarios:\n - Outdated binary: Clear warning with rebuild instructions\n - Newer binary: Info message that DB will be auto-upgraded\n✅ No warnings on subsequent runs (version updated automatically)\n\n**How it works:**\n1. On `bd init`: Stores current version in metadata table\n2. On every command: Checks stored version vs binary version\n3. If mismatch:\n - Binary \u003c DB version → Warn: outdated binary\n - Binary \u003e DB version → Info: auto-upgrading DB\n4. Always updates stored version to current (future-proof)\n\n**Files modified:**\n- cmd/bd/init.go: Store version on init\n- cmd/bd/main.go: checkVersionMismatch() + integration\n\n**Testing:**\n```bash\n# Simulate old binary\nsqlite3 .beads/default.db \"UPDATE metadata SET value='0.9.99' WHERE key='bd_version';\"\nbd ready # Shows warning\n\n# Normal use (versions match)\nbd ready # No warning\n```\n\n**Edge cases handled:**\n- Empty version (old DB): Silently upgrade\n- Metadata errors: Skip check (defensive)\n- Dev builds: String comparison (works for 0.9.5 vs 0.9.6)\n\nFixes bd-182 confusion (users won't run outdated binaries unknowingly).","status":"closed","priority":2,"issue_type":"feature","created_at":"2025-10-15T01:07:02.012291-07:00","updated_at":"2025-10-15T01:58:30.030043-07:00","dependencies":[{"issue_id":"bd-197","depends_on_id":"bd-182","type":"discovered-from","created_at":"2025-10-15T01:07:02.078326-07:00","created_by":"auto-import"}]}
