README.md\nAdd section explaining hash IDs:\n```markdown\n## Issue IDs\n\nBeads uses **hash-based IDs** for collision-free distributed issue tracking:\n\n- **Hash ID**: `bd-af78e9a2` (8-char SHA256 prefix, immutable, globally unique)\n- **Alias**: `#42` (sequential number, mutable, human-friendly)\n\n### Using IDs\n```bash\nbd show bd-af78e9a2 # Use hash ID\nbd show #42 # Use alias\nbd show 42 # Use alias (shorthand)\n```\n\n### Why Hash IDs?\n- **Collision-free**: Work offline without ID conflicts\n- **Distributed**: No coordination needed between clones\n- **Git-friendly**: Different IDs = different JSONL lines, fewer merge conflicts\n\n### Aliases\nAliases are workspace-local shortcuts for hash IDs. They're:\n- Automatically assigned on issue creation\n- Reassigned deterministically on sync (if conflicts)\n- Can be manually controlled with `bd alias` commands\n```\n\n### 2. AGENTS.md\nUpdate agent workflow:\n```markdown\n## Hash-Based IDs (v2.0+)\n\nBeads v2.0 uses hash-based IDs to eliminate collision problems:\n\n**When creating issues**:\n```bash\nbd create \"Fix bug\" -p 1\n# → Creates bd-af78e9a2 with alias #1\n```\n\n**When referencing issues**:\n- In text: Use hash IDs (stable): \"See bd-af78e9a2 for details\"\n- In CLI: Use aliases (readable): `bd update #42 --status done`\n\n**After sync**:\n- Alias conflicts resolved automatically (content-hash ordering)\n- No ID collisions possible\n- No remapping needed\n\n**Migration from v1.x**:\n```bash\nbd migrate --hash-ids # One-time migration\n```\n```\n\n### 3. QUICKSTART.md (if exists)\nShow alias usage in examples:\n```bash\n# Create issue (gets hash ID + alias)\nbd create \"Fix authentication bug\" -p 1\n# → Created bd-af78e9a2 (alias: #1)\n\n# Reference by alias\nbd show #1\nbd update #1 --status in_progress\nbd close #1 --reason \"Fixed\"\n```\n\n### 4. ADVANCED.md\nAdd section on hash ID internals:\n```markdown\n## Hash ID Generation\n\nHash IDs are generated deterministically:\n\n```go\nSHA256(title || description || timestamp || workspace_id)[:8]\n```\n\n**Collision probability**:\n- 8 hex chars = 2^32 space = ~4 billion IDs\n- Birthday paradox: 50% collision probability at ~65,000 issues\n- For typical projects (\u003c10,000 issues), collision risk is negligible\n\n**Collision detection**:\nIf a hash collision occurs (extremely rare), beads:\n1. Detects on insert (UNIQUE constraint)\n2. Appends random suffix: `bd-af78e9a2-a1b2`\n3. Retries insert\n\n## Alias Conflict Resolution\n\nWhen multiple clones assign same alias to different issues:\n\n**Strategy**: Content-hash ordering (deterministic)\n- Sort conflicting issue IDs lexicographically\n- Lowest hash ID keeps the alias\n- Others reassigned to next available aliases\n\n**Example**:\n```\nClone A: Assigns #42 to bd-a1b2c3d4\nClone B: Assigns #42 to bd-e5f6a7b8\nAfter sync: bd-a1b2c3d4 keeps #42 (lower hash)\n bd-e5f6a7b8 gets #100 (next available)\n```\n```\n\n### 5. MIGRATION.md (new file)\n```markdown\n# Migrating to Hash-Based IDs (v2.0)\n\n## Overview\nBeads v2.0 introduces hash-based IDs to eliminate collision problems. This is a **breaking change** requiring migration.\n\n## Migration Steps\n\n### 1. Backup\n```bash\ncp -r .beads .beads.backup\ngit commit -am \"Pre-migration backup\"\n```\n\n### 2. Run Migration\n```bash\n# Dry run first\nbd migrate --hash-ids --dry-run\n\n# Apply migration\nbd migrate --hash-ids\n```\n\n### 3. Commit Changes\n```bash\ngit add .beads/issues.jsonl\ngit commit -m \"Migrate to hash-based IDs (v2.0)\"\ngit push origin main\n```\n\n### 4. Coordinate with Collaborators\nAll clones must migrate before syncing:\n1. Notify team: \"Migrating to v2.0 on [date]\"\n2. All collaborators pull latest\n3. All run `bd migrate --hash-ids`\n4.

MCP Function Signatures (No Change)\nFunctions already use issue IDs as strings, so they work with hash IDs:\n\n```python\n# These already work!\nbeads_show(issue_id: str) # Accepts bd-af78e9a2 or #42\nbeads_update(issue_id: str, ...) # Accepts both formats\nbeads_close(issue_ids: List[str]) # Accepts both formats\n```\n\n### 2. Add Alias Resolution Helper\nFile: integrations/beads-mcp/src/beads_mcp/server.py\n\n```python\ndef resolve_issue_id(issue_id: str) -\u003e str:\n \"\"\"Resolve alias to hash ID if needed.\"\"\"\n # Hash ID: pass through\n if issue_id.startswith('bd-') and len(issue_id) == 11:\n return issue_id\n \n # Alias: #42 or 42\n alias_str = issue_id.lstrip('#')\n try:\n alias = int(alias_str)\n # Call bd to resolve\n result = subprocess.run(\n ['bd', 'alias', 'find', f'bd-{alias}'],\n capture_output=True, text=True\n )\n if result.returncode == 0:\n return result.stdout.strip()\n except ValueError:\n pass\n \n # Invalid format\n raise ValueError(f\"Invalid issue ID: {issue_id}\")\n```\n\n### 3. Update Response Formatting\nShow aliases in responses:\n\n```python\n@server.call_tool()\nasync def beads_show(issue_id: str) -\u003e List[TextContent]:\n resolved_id = resolve_issue_id(issue_id)\n \n result = subprocess.run(['bd', 'show', resolved_id], ...)\n \n # Parse response and add alias info\n # Format: \"bd-af78e9a2 (alias: #42)\"\n ...\n```\n\n### 4.

Update beads-mcp: `pip install --upgrade beads-mcp`\n2. Restart MCP server\n3. All existing workflows continue to work\n```\n\n### 6. Version Compatibility\nDetect and handle both v1.x and v2.0 formats:\n\n```python\ndef detect_beads_version() -\u003e str:\n \"\"\"Detect if beads is using sequential or hash IDs.\"\"\"\n result = subprocess.run(['bd', 'list', '-n', '1'], ...)\n first_id = parse_first_issue_id(result.stdout)\n \n if first_id.startswith('bd-') and len(first_id) \u003e 11:\n return '2.0' # Hash ID\n else:\n return '1.x' # Sequential ID\n\n# On startup\nbeads_version = detect_beads_version()\nlogger.info(f\"Detected beads version: {beads_version}\")\n```\n\n## Testing\n\n### Unit Tests\nFile: integrations/beads-mcp/tests/test_hash_ids.py\n\n```python\ndef test_resolve_hash_id():\n \"\"\"Hash IDs pass through unchanged.\"\"\"\n assert resolve_issue_id(\"bd-af78e9a2\") == \"bd-af78e9a2\"\n\ndef test_resolve_alias():\n \"\"\"Aliases resolve to hash IDs.\"\"\"\n # Mock bd alias find command\n assert resolve_issue_id(\"#42\") == \"bd-af78e9a2\"\n assert resolve_issue_id(\"42\") == \"bd-af78e9a2\"\n\ndef test_invalid_id():\n \"\"\"Invalid IDs raise ValueError.\"\"\"\n with pytest.raises(ValueError):\n resolve_issue_id(\"invalid\")\n```\n\n### Integration Tests\n```python\nasync def test_show_with_hash_id(mcp_server):\n result = await mcp_server.beads_show(issue_id=\"bd-af78e9a2\")\n assert \"bd-af78e9a2\" in result[0].text\n\nasync def test_show_with_alias(mcp_server):\n result = await mcp_server.beads_show(issue_id=\"#42\")\n assert \"bd-af78e9a2\" in result[0].text # Resolved\n```\n\n## Backward Compatibility\nThe MCP server should work with both:\n- Beads v1.x (sequential IDs)\n- Beads v2.0+ (hash IDs)\n\nDetection happens at runtime based on issue ID format.\n\n## Files to Modify\n- integrations/beads-mcp/src/beads_mcp/server.py\n- integrations/beads-mcp/README.md\n- integrations/beads-mcp/tests/test_hash_ids.py (new)\n- integrations/beads-mcp/pyproject.toml (bump version)\n\n## Deployment\n```bash\ncd integrations/beads-mcp\n# Bump version to 2.0.0\npoetry version 2.0.0\n# Publish to PyPI\npoetry publish --build\n```","status":"open","priority":1,"issue_type":"task","created_at":"2025-10-29T21:28:45.256074-07:00","updated_at":"2025-10-30T17:12:58.205384-07:00","dependencies":[{"issue_id":"bd-f8b764c9.2","depends_on_id":"bd-f8b764c9","type":"parent-child","created_at":"2025-10-29T21:28:45.257315-07:00","created_by":"stevey"},{"issue_id":"bd-f8b764c9.2","depends_on_id":"bd-f8b764c9.7","type":"blocks","created_at":"2025-10-29T21:28:45.258057-07:00","created_by":"stevey"}]} -{"id":"bd-f8b764c9.3","content_hash":"56929e57c09610ede74cd5d6f9e8dfa71c74412183cc53e646f72a2324025ad0","title":"Test: N-clone scenario with hash IDs (no collisions)","description":"Comprehensive test to verify hash IDs eliminate collision problems.\n\n## Test: TestHashIDsNClones\n\n### Purpose\nVerify that N clones can work offline and sync without ID collisions using hash IDs.\n\n### Test Scenario\n```\nSetup:\n- 1 bare remote repo\n- 5 clones (A, B, C, D, E)\n\nOffline Work:\n- Each clone creates 10 issues with different titles\n- No coordination, no network access\n- Total: 50 unique issues\n\nSync:\n- Clones sync in random order\n- Each pull/import other clones' issues\n\nExpected Result:\n- All 5 clones converge to 50 issues\n- Zero ID collisions\n- Zero remapping needed\n- Alias conflicts resolved deterministically\n```\n\n### Implementation\nFile: cmd/bd/beads_hashid_test.go (new)\n\n```go\nfunc TestHashIDsFiveClones(t *testing.T) {\n tmpDir := t.TempDir()\n remoteDir := setupBareRepo(t, tmpDir)\n \n // Setup 5 clones\n clones := make(map[string]string)\n for _, name := range []string{\"A\", \"B\", \"C\", \"D\", \"E\"} {\n clones[name] = setupClone(t, tmpDir, remoteDir, name)\n }\n \n // Each clone creates 10 issues offline\n for name, dir := range clones {\n for i := 0;

README.md\nAdd section explaining hash IDs:\n```markdown\n## Issue IDs\n\nBeads uses **hash-based IDs** for collision-free distributed issue tracking:\n\n- **Hash ID**: `bd-af78e9a2` (8-char SHA256 prefix, immutable, globally unique)\n- **Alias**: `#42` (sequential number, mutable, human-friendly)\n\n### Using IDs\n```bash\nbd show bd-af78e9a2 # Use hash ID\nbd show #42 # Use alias\nbd show 42 # Use alias (shorthand)\n```\n\n### Why Hash IDs?\n- **Collision-free**: Work offline without ID conflicts\n- **Distributed**: No coordination needed between clones\n- **Git-friendly**: Different IDs = different JSONL lines, fewer merge conflicts\n\n### Aliases\nAliases are workspace-local shortcuts for hash IDs. They're:\n- Automatically assigned on issue creation\n- Reassigned deterministically on sync (if conflicts)\n- Can be manually controlled with `bd alias` commands\n```\n\n### 2. AGENTS.md\nUpdate agent workflow:\n```markdown\n## Hash-Based IDs (v2.0+)\n\nBeads v2.0 uses hash-based IDs to eliminate collision problems:\n\n**When creating issues**:\n```bash\nbd create \"Fix bug\" -p 1\n# → Creates bd-af78e9a2 with alias #1\n```\n\n**When referencing issues**:\n- In text: Use hash IDs (stable): \"See bd-af78e9a2 for details\"\n- In CLI: Use aliases (readable): `bd update #42 --status done`\n\n**After sync**:\n- Alias conflicts resolved automatically (content-hash ordering)\n- No ID collisions possible\n- No remapping needed\n\n**Migration from v1.x**:\n```bash\nbd migrate --hash-ids # One-time migration\n```\n```\n\n### 3. QUICKSTART.md (if exists)\nShow alias usage in examples:\n```bash\n# Create issue (gets hash ID + alias)\nbd create \"Fix authentication bug\" -p 1\n# → Created bd-af78e9a2 (alias: #1)\n\n# Reference by alias\nbd show #1\nbd update #1 --status in_progress\nbd close #1 --reason \"Fixed\"\n```\n\n### 4. ADVANCED.md\nAdd section on hash ID internals:\n```markdown\n## Hash ID Generation\n\nHash IDs are generated deterministically:\n\n```go\nSHA256(title || description || timestamp || workspace_id)[:8]\n```\n\n**Collision probability**:\n- 8 hex chars = 2^32 space = ~4 billion IDs\n- Birthday paradox: 50% collision probability at ~65,000 issues\n- For typical projects (\u003c10,000 issues), collision risk is negligible\n\n**Collision detection**:\nIf a hash collision occurs (extremely rare), beads:\n1. Detects on insert (UNIQUE constraint)\n2. Appends random suffix: `bd-af78e9a2-a1b2`\n3. Retries insert\n\n## Alias Conflict Resolution\n\nWhen multiple clones assign same alias to different issues:\n\n**Strategy**: Content-hash ordering (deterministic)\n- Sort conflicting issue IDs lexicographically\n- Lowest hash ID keeps the alias\n- Others reassigned to next available aliases\n\n**Example**:\n```\nClone A: Assigns #42 to bd-a1b2c3d4\nClone B: Assigns #42 to bd-e5f6a7b8\nAfter sync: bd-a1b2c3d4 keeps #42 (lower hash)\n bd-e5f6a7b8 gets #100 (next available)\n```\n```\n\n### 5. MIGRATION.md (new file)\n```markdown\n# Migrating to Hash-Based IDs (v2.0)\n\n## Overview\nBeads v2.0 introduces hash-based IDs to eliminate collision problems. This is a **breaking change** requiring migration.\n\n## Migration Steps\n\n### 1. Backup\n```bash\ncp -r .beads .beads.backup\ngit commit -am \"Pre-migration backup\"\n```\n\n### 2. Run Migration\n```bash\n# Dry run first\nbd migrate --hash-ids --dry-run\n\n# Apply migration\nbd migrate --hash-ids\n```\n\n### 3. Commit Changes\n```bash\ngit add .beads/issues.jsonl\ngit commit -m \"Migrate to hash-based IDs (v2.0)\"\ngit push origin main\n```\n\n### 4. Coordinate with Collaborators\nAll clones must migrate before syncing:\n1. Notify team: \"Migrating to v2.0 on [date]\"\n2. All collaborators pull latest\n3. All run `bd migrate --hash-ids`\n4. All push changes\n5. Resume normal work\n\n## Rollback\n```bash\n# Restore backup\nmv .beads.backup .beads\nbd export # Regenerate JSONL\ngit checkout .beads/issues.jsonl\n```\n\n## FAQ\n\n**Q: Can I mix v1.x and v2.0 clones?**\nA: No. All clones must be on same version.\n\n**Q: Will my old issue IDs work?**\nA: No, but aliases preserve the numbers: bd-1c63eb84 → #1\n\n**Q: What happens to links like \"see bd-cb64c226.3\"?**\nA: Migration updates all text references automatically.\n```\n\n### 6.

Add Alias Resolution Helper\nFile: integrations/beads-mcp/src/beads_mcp/server.py\n\n```python\ndef resolve_issue_id(issue_id: str) -\u003e str:\n \"\"\"Resolve alias to hash ID if needed.\"\"\"\n # Hash ID: pass through\n if issue_id.startswith('bd-') and len(issue_id) == 11:\n return issue_id\n \n # Alias: #42 or 42\n alias_str = issue_id.lstrip('#')\n try:\n alias = int(alias_str)\n # Call bd to resolve\n result = subprocess.run(\n ['bd', 'alias', 'find', f'bd-{alias}'],\n capture_output=True, text=True\n )\n if result.returncode == 0:\n return result.stdout.strip()\n except ValueError:\n pass\n \n # Invalid format\n raise ValueError(f\"Invalid issue ID: {issue_id}\")\n```\n\n### 3. Update Response Formatting\nShow aliases in responses:\n\n```python\n@server.call_tool()\nasync def beads_show(issue_id: str) -\u003e List[TextContent]:\n resolved_id = resolve_issue_id(issue_id)\n \n result = subprocess.run(['bd', 'show', resolved_id], ...)\n \n # Parse response and add alias info\n # Format: \"bd-af78e9a2 (alias: #42)\"\n ...\n```\n\n### 4. Add beads_alias_* Functions\n\n```python\n@server.call_tool()\nasync def beads_alias_list() -\u003e List[TextContent]:\n \"\"\"List all alias mappings.\"\"\"\n result = subprocess.run(['bd', 'alias', 'list'], ...)\n return [TextContent(type=\"text\", text=result.stdout)]\n\n@server.call_tool()\nasync def beads_alias_set(alias: int, issue_id: str) -\u003e List[TextContent]:\n \"\"\"Manually assign alias to issue.\"\"\"\n result = subprocess.run(['bd', 'alias', 'set', str(alias), issue_id], ...)\n return [TextContent(type=\"text\", text=result.stdout)]\n\n@server.call_tool()\nasync def beads_alias_compact() -\u003e List[TextContent]:\n \"\"\"Compact aliases to fill gaps.\"\"\"\n result = subprocess.run(['bd', 'alias', 'compact'], ...)\n return [TextContent(type=\"text\", text=result.stdout)]\n```\n\n### 5. Update Documentation\nFile: integrations/beads-mcp/README.md\n\n```markdown\n## Issue IDs (v2.0+)\n\nThe MCP server accepts both hash IDs and aliases:\n\n```python\n# Using hash IDs\nawait beads_show(issue_id=\"bd-af78e9a2\")\n\n# Using aliases\nawait beads_show(issue_id=\"#42\")\nawait beads_show(issue_id=\"42\") # Shorthand\n```\n\n## Alias Management\n\nNew functions for alias control:\n\n- `beads_alias_list()` - List all alias mappings\n- `beads_alias_set(alias, issue_id)` - Manually assign alias\n- `beads_alias_compact()` - Compact aliases to fill gaps\n\n## Migration\n\nAfter migrating to hash IDs:\n1. Update beads-mcp: `pip install --upgrade beads-mcp`\n2. Restart MCP server\n3. All existing workflows continue to work\n```\n\n### 6. Version Compatibility\nDetect and handle both v1.x and v2.0 formats:\n\n```python\ndef detect_beads_version() -\u003e str:\n \"\"\"Detect if beads is using sequential or hash IDs.\"\"\"\n result = subprocess.run(['bd', 'list', '-n', '1'], ...)\n first_id = parse_first_issue_id(result.stdout)\n \n if first_id.startswith('bd-') and len(first_id) \u003e 11:\n return '2.0' # Hash ID\n else:\n return '1.x' # Sequential ID\n\n# On startup\nbeads_version = detect_beads_version()\nlogger.info(f\"Detected beads version: {beads_version}\")\n```\n\n## Testing\n\n### Unit Tests\nFile: integrations/beads-mcp/tests/test_hash_ids.py\n\n```python\ndef test_resolve_hash_id():\n \"\"\"Hash IDs pass through unchanged.\"\"\"\n assert resolve_issue_id(\"bd-af78e9a2\") == \"bd-af78e9a2\"\n\ndef test_resolve_alias():\n \"\"\"Aliases resolve to hash IDs.\"\"\"\n # Mock bd alias find command\n assert resolve_issue_id(\"#42\") == \"bd-af78e9a2\"\n assert resolve_issue_id(\"42\") == \"bd-af78e9a2\"\n\ndef test_invalid_id():\n \"\"\"Invalid IDs raise ValueError.\"\"\"\n with pytest.raises(ValueError):\n resolve_issue_id(\"invalid\")\n```\n\n### Integration Tests\n```python\nasync def test_show_with_hash_id(mcp_server):\n result = await mcp_server.beads_show(issue_id=\"bd-af78e9a2\")\n assert \"bd-af78e9a2\" in result[0].text\n\nasync def test_show_with_alias(mcp_server):\n result = await mcp_server.beads_show(issue_id=\"#42\")\n assert \"bd-af78e9a2\" in result[0].text # Resolved\n```\n\n## Backward Compatibility\nThe MCP server should work with both:\n- Beads v1.x (sequential IDs)\n- Beads v2.0+ (hash IDs)\n\nDetection happens at runtime based on issue ID format.\n\n## Files to Modify\n- integrations/beads-mcp/src/beads_mcp/server.py\n- integrations/beads-mcp/README.md\n- integrations/beads-mcp/tests/test_hash_ids.py (new)\n- integrations/beads-mcp/pyproject.toml (bump version)\n\n## Deployment\n```bash\ncd integrations/beads-mcp\n# Bump version to 2.0.0\npoetry version 2.0.0\n# Publish to PyPI\npoetry publish --build\n```","status":"closed","priority":1,"issue_type":"task","created_at":"2025-10-29T21:28:45.256074-07:00","updated_at":"2025-10-31T12:32:32.60786-07:00","closed_at":"2025-10-31T12:32:32.60786-07:00","dependencies":[{"issue_id":"bd-f8b764c9.2","depends_on_id":"bd-f8b764c9","type":"parent-child","created_at":"2025-10-29T21:28:45.257315-07:00","created_by":"stevey"},{"issue_id":"bd-f8b764c9.2","depends_on_id":"bd-f8b764c9.7","type":"blocks","created_at":"2025-10-29T21:28:45.258057-07:00","created_by":"stevey"}]} +{"id":"bd-f8b764c9.3","content_hash":"56929e57c09610ede74cd5d6f9e8dfa71c74412183cc53e646f72a2324025ad0","title":"Test: N-clone scenario with hash IDs (no collisions)","description":"Comprehensive test to verify hash IDs eliminate collision problems.\n\n## Test: TestHashIDsNClones\n\n### Purpose\nVerify that N clones can work offline and sync without ID collisions using hash IDs.\n\n### Test Scenario\n```\nSetup:\n- 1 bare remote repo\n- 5 clones (A, B, C, D, E)\n\nOffline Work:\n- Each clone creates 10 issues with different titles\n- No coordination, no network access\n- Total: 50 unique issues\n\nSync:\n- Clones sync in random order\n- Each pull/import other clones' issues\n\nExpected Result:\n- All 5 clones converge to 50 issues\n- Zero ID collisions\n- Zero remapping needed\n- Alias conflicts resolved deterministically\n```\n\n### Implementation\nFile: cmd/bd/beads_hashid_test.go (new)\n\n```go\nfunc TestHashIDsFiveClones(t *testing.T) {\n tmpDir := t.TempDir()\n remoteDir := setupBareRepo(t, tmpDir)\n \n // Setup 5 clones\n clones := make(map[string]string)\n for _, name := range []string{\"A\", \"B\", \"C\", \"D\", \"E\"} {\n clones[name] = setupClone(t, tmpDir, remoteDir, name)\n }\n \n // Each clone creates 10 issues offline\n for name, dir := range clones {\n for i := 0;
