feat: Phase Q — Merge Queue & Automation System

Implement comprehensive GitHub automation infrastructure to handle 50+ concurrent PRs
through intelligent auto-merge, workflow bucketing, and merge queue management.

## Documentation (5 files)
- MERGE_QUEUE_PLAN.md - Master plan for merge queue implementation
- GITHUB_AUTOMATION_RULES.md - Complete automation policies and rules
- AUTO_MERGE_POLICY.md - 8-tier auto-merge decision framework
- WORKFLOW_BUCKETING_EXPLAINED.md - Module-specific CI documentation
- OPERATOR_PR_EVENT_HANDLERS.md - GitHub webhook integration guide
- docs/architecture/merge-flow.md - Event flow architecture

## GitHub Workflows (13 files)
Auto-Labeling:
- .github/labeler.yml - File-based automatic PR labeling
- .github/workflows/label-pr.yml - PR labeling workflow

Auto-Approval (3 tiers):
- .github/workflows/auto-approve-docs.yml - Tier 1 (docs-only)
- .github/workflows/auto-approve-tests.yml - Tier 2 (tests-only)
- .github/workflows/auto-approve-ai.yml - Tier 4 (AI-generated)

Auto-Merge:
- .github/workflows/auto-merge.yml - Main auto-merge orchestration

Bucketed CI (6 modules):
- .github/workflows/backend-ci-bucketed.yml - Backend tests
- .github/workflows/frontend-ci-bucketed.yml - Frontend validation
- .github/workflows/agents-ci-bucketed.yml - Agent tests
- .github/workflows/docs-ci-bucketed.yml - Documentation linting
- .github/workflows/infra-ci-bucketed.yml - Infrastructure validation
- .github/workflows/sdk-ci-bucketed.yml - SDK tests (Python & TypeScript)

## Configuration
- .github/CODEOWNERS - Rewritten with module-based ownership + team aliases
- .github/pull_request_template.md - PR template with auto-merge indicators

## Backend Implementation
- backend/app/services/github_events.py - GitHub webhook event handlers
  - Routes events to appropriate handlers
  - Logs to database for audit trail
  - Emits OS events to Operator Engine
  - Notifies Prism Console via WebSocket

## Frontend Implementation
- blackroad-os/js/apps/prism-merge-dashboard.js - Real-time merge queue dashboard
  - WebSocket-based live updates
  - Queue visualization
  - Metrics tracking (PRs/day, avg time, auto-merge rate)
  - User actions (refresh, export, GitHub link)

## Key Features
✅ 8-tier auto-merge system (docs → tests → scaffolds → AI → deps → infra → breaking → security)
✅ Module-specific CI (only run relevant tests, 60% cost reduction)
✅ Automatic PR labeling (file-based, size-based, author-based)
✅ Merge queue management (prevents race conditions)
✅ Real-time dashboard (Prism Console integration)
✅ Full audit trail (database logging)
✅ Soak time for AI PRs (5-minute human review window)
✅ Comprehensive CODEOWNERS (module ownership + auto-approve semantics)

## Expected Impact
- 10x PR throughput (5 → 50 PRs/day)
- 90% automation rate (only complex PRs need human review)
- 3-5x faster CI (workflow bucketing)
- Zero merge conflicts (queue manages sequential merging)
- Full visibility (Prism dashboard)

## Next Steps for Alexa
1. Enable merge queue on main branch (GitHub UI → Settings → Branches)
2. Configure branch protection rules (require status checks)
3. Set GITHUB_WEBHOOK_SECRET environment variable (for webhook validation)
4. Test with sample PRs (docs-only, AI-generated)
5. Monitor Prism dashboard for queue status
6. Adjust policies based on metrics

See MERGE_QUEUE_PLAN.md for complete implementation checklist.

Phase Q complete, Operator. Your merge queues are online. 🚀

+# 🔀 AUTO-MERGE POLICY
+
+> **BlackRoad Operating System — Phase Q**
+> **Purpose**: Define when and how PRs automatically merge
+> **Owner**: Operator Alexa (Cadillac)
+> **Last Updated**: 2025-11-18
+
+---
+
+## Policy Overview
+
+This document defines the **official policy** for automatic PR merging in the BlackRoad GitHub organization.
+
+**Philosophy**: **Automate the safe, delegate the complex, escalate the critical**
+
+---
+
+## Auto-Merge Decision Tree
+
+```
+PR Created
+    │
+    ├─> Has 'do-not-merge' label? ─────> ❌ BLOCK (manual only)
+    │
+    ├─> Has 'breaking-change' label? ──> ❌ BLOCK (human review required)
+    │
+    ├─> Has 'security' label? ─────────> ❌ BLOCK (security review required)
+    │
+    ├─> Has 'wip' label? ──────────────> ❌ BLOCK (work in progress)

+
+## Auto-Merge Tiers
+
+### Tier 1: Documentation (Immediate Auto-Merge)
+
+**Criteria**:
+- ✅ Only files in `docs/`, `*.md` (excluding `SECURITY.md`)
+- ✅ Markdown linting passes
+- ✅ No `breaking-change` label
+- ✅ No `security` label
+
+**Approval**: Automatic (docs-bot)
+**Soak Time**: 0 minutes
+**Merge Method**: Squash
+**Rationale**: Documentation changes are low-risk and high-value
+
+**Example PRs**:
+- Fix typo in README
+- Add API documentation
+- Update architecture diagrams
+- Expand user guide
+
+**Blockers**:
+- ❌ Changes to `SECURITY.md` (requires human review)
+- ❌ Changes to `.github/` workflows (infra, not docs)
+
+---
+
+### Tier 2: Tests (Immediate Auto-Merge)
+
+**Criteria**:
+- ✅ Only files in `**/tests/`, `**/*test*.py`, `**/*.test.js`
+- ✅ All existing tests pass
+- ✅ New tests pass (if added)
+- ✅ Code coverage does not decrease
+- ✅ No `breaking-change` label
+
+**Approval**: Automatic (test-bot)
+**Soak Time**: 0 minutes
+**Merge Method**: Squash
+**Rationale**: More tests = better quality, hard to break prod with tests
+
+**Example PRs**:
+- Add unit tests for auth module
+- Add integration tests for API
+- Add E2E tests for UI flow
+- Improve test coverage
+
+**Blockers**:
+- ❌ Tests fail
+- ❌ Code coverage decreases
+- ❌ Test files + production code (mixed change)
+
+---
+
+### Tier 3: Scaffolding (5-Minute Soak, Auto-Merge)
+
+**Criteria**:
+- ✅ New files only (no modifications to existing files)
+- ✅ Mostly comments, type stubs, TODOs, or template code
+- ✅ Linting/type checking passes
+- ✅ Size: < 200 lines
+- ✅ No logic errors (syntax errors fail CI)
+
+**Approval**: Automatic (scaffold-bot)
+**Soak Time**: 5 minutes
+**Merge Method**: Squash
+**Rationale**: Scaffolds are placeholders, reviewed during implementation
+
+**Example PRs**:
+- Create empty route handlers
+- Add type definitions
+- Create database model stubs
+- Add placeholder components
+
+**Blockers**:
+- ❌ Modifies existing files
+- ❌ Contains complex logic
+- ❌ Size > 200 lines
+
+---
+
+### Tier 4: AI-Generated (5-Minute Soak, Auto-Merge)
+
+**Criteria**:
+- ✅ Label: `claude-auto`, `atlas-auto`, or `codex-auto`
+- ✅ **All** CI checks pass (backend, frontend, security, linting)
+- ✅ Size: < 500 lines (larger PRs need human review)
+- ✅ No `breaking-change` label
+- ✅ No `security` label
+- ✅ No changes to `.github/workflows/` (workflow changes need review)
+
+**Approval**: Automatic (ai-review-bot) after all checks pass
+**Soak Time**: 5 minutes (allows human override)
+**Merge Method**: Squash
+**Rationale**: AI agents write good code, tests validate correctness
+
+**Example PRs**:
+- Claude adds new API endpoint
+- Atlas implements UI component
+- Codex refactors module
+- Agent fixes bug
+
+**Blockers**:
+- ❌ Any CI check fails
+- ❌ Breaking change detected
+- ❌ Security vulnerability found
+- ❌ PR size > 500 lines
+- ❌ Modifies workflows or infrastructure
+
+**Soak Time Rationale**:
+- Gives humans 5 minutes to review PR if they want
+- Allows manual merge or changes before auto-merge
+- Prevents immediate deployment of potentially risky changes
+
+---
+
+### Tier 5: Dependencies (30-Minute Soak, Auto-Merge)
+
+**Criteria**:
+- ✅ Author: `dependabot[bot]`
+- ✅ Change type: Patch or minor version bump (not major)
+- ✅ Security scan passes (no new vulnerabilities)
+- ✅ All tests pass with new dependency version
+- ✅ No breaking changes in dependency changelog
+
+**Approval**: Automatic (dependabot-auto-approve) after checks pass
+**Soak Time**: 30 minutes (security review window)
+**Merge Method**: Squash
+**Rationale**: Patch/minor bumps are usually safe, tests catch regressions
+
+**Example PRs**:
+- Bump fastapi from 0.104.1 to 0.104.2 (patch)
+- Bump pytest from 7.4.3 to 7.5.0 (minor)
+- Bump eslint from 8.50.0 to 8.51.0 (minor)
+
+**Blockers**:
+- ❌ Major version bump (e.g., 1.0.0 → 2.0.0)
+- ❌ Security vulnerability in new version
+- ❌ Tests fail with new version
+- ❌ Breaking changes in changelog
+
+**Major Version Bumps**:
+- Require human review (may have breaking changes)
+- Need changelog review
+- May require code changes
+
+---
+
+## Manual Merge Required
+
+### Tier 6: Infrastructure (No Auto-Merge)
+
+**Files**:
+- `.github/workflows/**`
+- `infra/**`
+- `ops/**`
+- `Dockerfile`, `docker-compose.yml`
+- `railway.toml`, `railway.json`
+- `.github/CODEOWNERS`
+
+**Approval**: Human required
+**Merge**: Human clicks merge button
+**Rationale**: Infrastructure changes have high blast radius
+
+**Example PRs**:
+- Modify CI/CD pipeline
+- Change deployment configuration
+- Update Docker image
+- Modify branch protection rules
+
+**Exception**:
+- Small docs changes in workflow files (e.g., comments) may auto-merge if clearly non-functional
+
+---
+
+### Tier 7: Breaking Changes (No Auto-Merge)
+
+**Indicators**:
+- Label: `breaking-change` (manually applied)
+- API contract changes
+- Database schema migrations (destructive)
+- Configuration format changes
+- Major dependency version bumps
+
+**Approval**: Human required + stakeholder notification
+**Merge**: Human clicks merge button
+**Rationale**: Breaking changes need coordination across team/users
+
+**Example PRs**:
+- Remove deprecated API endpoint
+- Change required environment variables
+- Modify database column types
+- Rename public functions
+
+**Process**:
+1. PR author applies `breaking-change` label
+2. PR author documents migration path
+3. Stakeholders review and approve
+4. Announce to team before merge
+5. Human manually merges
+6. Monitor for issues post-merge
+
+---
+
+### Tier 8: Security (No Auto-Merge)
+
+**Indicators**:
+- Label: `security` (manually applied)
+- Security scan detects issues
+- Changes to authentication/authorization
+- Changes to encryption/secrets handling
+- Changes to `SECURITY.md`
+
+**Approval**: Security reviewer required (human)
+**Merge**: Human clicks merge button after security review
+**Rationale**: Security issues need expert review
+
+**Example PRs**:
+- Fix SQL injection vulnerability
+- Update JWT secret rotation
+- Patch XSS vulnerability
+- Change password hashing algorithm
+
+**Process**:
+1. PR author applies `security` label
+2. Security reviewer audits code
+3. Security reviewer approves
+4. Human manually merges
+5. Security team monitors deployment
+
+---
+
+## Auto-Merge Configuration
+
+### GitHub Actions Workflow
+
+**File**: `.github/workflows/auto-merge.yml`
+
+**Trigger Events**:
+```yaml
+on:
+  pull_request_review:
+    types: [submitted]       # When PR is approved
+  status: {}                 # When status checks update
+  check_run:
+    types: [completed]       # When individual check completes
+  pull_request:
+    types: [labeled]         # When label added (e.g., 'auto-merge')

+
+## Safeguards
+
+### Pre-Merge Checks
+
+Before any auto-merge:
+
+1. ✅ **All required status checks pass**
+   - Backend tests
+   - Frontend validation
+   - Security scan
+   - Linting
+
+2. ✅ **At least 1 approval** (can be bot)
+   - Auto-approval for Tier 1-5
+   - Human approval for Tier 6-8
+
+3. ✅ **No blocking labels**
+   - No `do-not-merge`
+   - No `wip`
+   - No `needs-review` (unless auto-approved)
+
+4. ✅ **No merge conflicts**
+   - Branch is up to date
+   - Or in merge queue (will rebase)
+
+5. ✅ **Conversations resolved**
+   - All review comments addressed
+   - No outstanding questions
+
+### Post-Merge Actions
+
+After auto-merge:
+
+1. 📝 **Log event** to database
+   - PR number, title, author
+   - Merge time, merge method
+   - Approval source (bot or human)
+   - Labels present at merge time
+
+2. 📢 **Notify stakeholders**
+   - PR author (GitHub comment)
+   - CODEOWNERS (GitHub mention)
+   - Operator dashboard (event)
+
+3. 🗑️ **Delete branch**
+   - Auto-delete feature branch
+   - Keep main/production branches
+
+4. 📊 **Update metrics**
+   - Throughput counter
+   - Time-to-merge average
+   - Auto-merge success rate
+
+---
+
+## Override Mechanisms
+
+### Disabling Auto-Merge
+
+**For a specific PR**:
+```bash
+# Add blocking label
+gh pr edit <PR_NUMBER> --add-label "do-not-merge"
+
+# Remove auto-merge label
+gh pr edit <PR_NUMBER> --remove-label "auto-merge"
+```
+
+**For all PRs temporarily**:
+```bash
+# Disable auto-merge workflow
+gh workflow disable auto-merge.yml
+
+# Re-enable later
+gh workflow enable auto-merge.yml
+```
+
+### Emergency Stop
+
+If auto-merge causes issues:
+
+1. **Immediately disable workflow**:
+   ```bash
+   gh workflow disable auto-merge.yml
+   ```
+
+2. **Revert problematic merge**:
+   ```bash
+   git revert <commit-sha>
+   git push origin main
+   ```
+
+3. **Investigate root cause**:
+   - Which tier allowed the merge?
+   - What checks should have caught it?
+   - Update policy to prevent recurrence
+
+4. **Re-enable with updated rules**:
+   ```bash
+   gh workflow enable auto-merge.yml
+   ```
+
+---
+
+## Metrics & KPIs
+
+### Success Metrics
+
+| Metric | Target | Measurement |
+|--------|--------|-------------|
+| **Auto-merge success rate** | > 95% | (Successful merges / Total attempts) |
+| **False positive rate** | < 2% | (Reverted PRs / Auto-merged PRs) |
+| **Time-to-merge (auto)** | < 30 min | From PR open to merge |
+| **Time-to-merge (manual)** | < 4 hours | From PR open to merge |
+| **Auto-merge adoption** | > 80% | (Auto-merged PRs / Total PRs) |
+
+### Failure Modes
+
+Track reasons for auto-merge failures:
+- Merge conflicts
+- Check failures
+- Queue timeouts
+- GitHub API errors
+
+**Action**: Optimize most common failure mode
+
+---
+
+## Policy Evolution
+
+### Review Cadence
+
+**Weekly**:
+- Review auto-merged PRs (spot check)
+- Check metrics (success rate, time-to-merge)
+- Identify issues
+
+**Monthly**:
+- Analyze failure modes
+- Adjust tier criteria if needed
+- Expand auto-merge to new categories (if safe)
+
+**Quarterly**:
+- Comprehensive policy review
+- Update based on learnings
+- Adjust soak times based on data
+
+### Adding New Categories
+
+To add a new auto-merge category:
+
+1. **Propose criteria** (be conservative)
+2. **Test with manual approval first** (1 week)
+3. **Enable auto-approval with long soak time** (1 week)
+4. **Reduce soak time if successful** (gradual)
+5. **Document as new tier** (update this doc)
+
+### Removing Categories
+
+If a tier has high false positive rate:
+
+1. **Increase soak time** (give more review window)
+2. **Tighten criteria** (make rules more strict)
+3. **Require human approval** (disable auto-approval)
+4. **Remove from auto-merge** (manual merge only)
+

+8. [Exception Handling](#exception-handling)
+
+---
+
+## Overview
+
+This document defines **all automation rules** for the BlackRoad GitHub organization. These rules govern:
+
+- **When** PRs are automatically labeled
+- **Which** PRs can be auto-approved
+- **What** conditions trigger auto-merge
+- **How** workflows are triggered
+- **Who** gets notified about what
+
+**Guiding Principles**:
+1. **Safety First** — When in doubt, require human review
+2. **Progressive Enhancement** — Start conservative, expand as confidence grows
+3. **Transparency** — All automation actions are logged and visible
+4. **Escape Hatches** — Humans can always override automation
+5. **Fail Safe** — Errors block automation, don't proceed blindly
+
+---
+
+## Labeling Rules

+      github.event.state == 'success' &&
+      !contains(github.event.pull_request.labels.*.name, 'breaking-change')
+    runs-on: ubuntu-latest
+    steps:
+      - name: Check PR size

+
+✅ **Action**: Auto-approve patch/minor, require review for major
+✅ **Approver**: `dependabot-auto-approve`
+
+### When NOT to Auto-Approve
+
+❌ **NEVER** auto-approve if:
+- Contains `breaking-change` label
+- Contains `security` label
+- Contains `needs-review` label
+- Contains `do-not-merge` label
+- Changes `.github/workflows/` (workflow changes need human review)
+- Changes `infra/` (infrastructure changes need human review)
+- Changes CODEOWNERS (ownership changes need human review)
+- Changes Dockerfile or docker-compose.yml (container changes need review)
+- PR author is not recognized (unknown bot or user)
+- Any required check fails
+- PR has conflicts with main branch
+
+---
+
+## Auto-Merge Rules
+
+### When to Auto-Merge
+
+A PR is **automatically merged** if it meets **ALL** of these criteria:
+
+#### Required Conditions (All Tiers)
+
+1. ✅ **Approved**: At least 1 approval (can be auto-approval bot)
+2. ✅ **Checks Passing**: All required status checks pass
+3. ✅ **Up to Date**: Branch is current (or in merge queue)
+4. ✅ **No Conflicts**: No merge conflicts
+5. ✅ **Labeled**: Has one of: `auto-merge`, `claude-auto`, `docs-only`, `merge-ready`
+6. ✅ **Not Blocked**: No `do-not-merge`, `wip`, `needs-review` labels
+
+#### Tier-Specific Conditions
+
+**Docs-Only PRs**:
+- ✅ Auto-approve + auto-merge enabled
+- ✅ Markdown linting passes
+- ⏱️ Merge immediately
+
+**Test-Only PRs**:
+- ✅ Auto-approve + auto-merge enabled
+- ✅ All tests pass (including new tests)
+- ⏱️ Merge immediately
+
+**AI-Generated PRs** (`claude-auto`, `atlas-auto`):
+- ✅ Auto-approve + auto-merge enabled
+- ✅ **All** CI checks pass (backend, frontend, security)
+- ✅ No `breaking-change` label
+- ⏱️ Merge after 5-minute soak time (allows human override)
+
+**Infrastructure PRs**:
+- ⚠️ **Manual merge required** (even if approved)
+- Rationale: High-risk changes need human verification
+
+**Breaking Changes**:
+- ❌ **Never auto-merge**
+- Rationale: API changes need human coordination
+
+### Merge Method
+
+**Default**: `squash`
+- Keeps clean history
+- Easy to revert
+- Good commit messages
+
+**Exceptions**:
+- `merge` for feature branches with detailed history
+- `rebase` for single-commit PRs (rare)
+
+**Configuration**:
+```yaml
+# .github/auto-merge.yml
+env:
+  MERGE_METHOD: squash
+  MERGE_COMMIT_MESSAGE: PR_TITLE
+  MERGE_DELETE_BRANCH: true
+```
+
+### Soak Time
+
+**Purpose**: Give humans a window to intervene before auto-merge
+
+| PR Type | Soak Time | Rationale |
+|---------|-----------|-----------|
+| Docs-only | 0 min | Very low risk |
+| Tests-only | 0 min | Low risk |
+| Scaffolding | 5 min | Human can spot-check |
+| AI-generated | 5 min | Human can review if needed |
+| Dependencies | 30 min | Security review window |
+
+**Implementation**:
+```yaml
+# .github/workflows/auto-merge.yml
+- name: Wait soak time
+  if: contains(github.event.pull_request.labels.*.name, 'claude-auto')
+  run: sleep 300  # 5 minutes
+```
+
+---
+
+## Branch Protection Rules
+
+### Main Branch Protection
+
+**Branch**: `main` (production)
+
+**Rules**:
+- ✅ **Require pull request** before merging
+- ✅ **Require approvals**: 1 (can be auto-approval bot)
+- ✅ **Require status checks** to pass before merging
+  - Backend Tests
+  - Frontend Validation
+  - Security Scan
+  - Markdown Linting (for docs changes)
+- ✅ **Require branches to be up to date** before merging
+- ✅ **Require merge queue** (prevents race conditions)
+- ✅ **Require conversation resolution** before merging
+- ❌ **Do not allow force pushes** (even admins)
+- ❌ **Do not allow deletions**
+
+**Bypass Allowed**: Only in emergencies, with audit log
+
+### Feature Branch Protection
+
+**Branches**: `feature/*`, `claude/*`, `atlas/*`
+
+**Rules**:
+- ⚠️ No protection (development branches)
+- ✅ Auto-delete after merge
+
+---
+
+## Workflow Trigger Rules
+
+### Path-Based Triggers
+
+Workflows only run when relevant files change.
+
+**Backend CI** (`backend-ci.yml`):
+```yaml
+on:
+  pull_request:
+    paths:
+      - 'backend/**'
+      - 'requirements.txt'
+      - 'Dockerfile'
+      - 'docker-compose.yml'
+  push:
+    branches: [main]
+    paths:
+      - 'backend/**'
+```
+
+**Frontend CI** (`frontend-ci.yml`):
+```yaml
+on:
+  pull_request:
+    paths:
+      - 'blackroad-os/**'
+      - 'backend/static/**'
+  push:
+    branches: [main]
+    paths:
+      - 'blackroad-os/**'
+      - 'backend/static/**'
+```
+
+**Docs CI** (`docs-ci.yml`):
+```yaml
+on:
+  pull_request:
+    paths:
+      - 'docs/**'
+      - '*.md'
+  push:
+    branches: [main]
+    paths:
+      - 'docs/**'
+      - '*.md'
+```
+
+**Agents CI** (`agents-ci.yml`):
+```yaml
+on:
+  pull_request:
+    paths:
+      - 'agents/**'
+  push:
+    branches: [main]
+    paths:
+      - 'agents/**'
+```
+
+**Infrastructure CI** (`infra-ci.yml`):
+```yaml
+on:
+  pull_request:
+    paths:
+      - 'infra/**'
+      - 'ops/**'
+      - '.github/**'
+      - '*.toml'
+      - '*.json'
+  push:
+    branches: [main]
+    paths:
+      - 'infra/**'
+      - '.github/**'
+```
+
+### Event-Based Triggers
+
+**Auto-Merge Workflow**:
+```yaml
+on:
+  pull_request_review:
+    types: [submitted]  # Triggered when PR is approved
+  status: {}            # Triggered when CI checks complete
+  check_run:
+    types: [completed]  # Triggered when individual check completes
+```
+
+**Auto-Labeling Workflow**:
+```yaml
+on:
+  pull_request:
+    types: [opened, synchronize, reopened]  # Triggered on PR create/update
+```
+
+**Notification Workflow**:
+```yaml
+on:
+  pull_request:
+    types: [opened, closed, merged]  # Triggered on PR lifecycle events
+```
+
+---
+
+## Notification Rules
+
+### Who Gets Notified When
+
+**PR Opened**:
+- 📢 **CODEOWNERS** for affected paths
+- 📢 **Operator Team** (via Prism Console)
+- 📧 **Email** (if subscribed)
+
+**PR Approved**:
+- 📢 **PR Author**
+- 📢 **Reviewers** (FYI)
+
+**PR Auto-Merged**:
+- 📢 **PR Author** (GitHub comment)
+- 📢 **CODEOWNERS** (GitHub comment)
+- 📢 **Operator Dashboard** (event log)
+- 📧 **Daily Digest** (all auto-merges)
+
+**PR Failed Checks**:
+- 🚨 **PR Author** (GitHub comment with details)
+- 📢 **Reviewers** (if already reviewing)
+- 📊 **Prism Console** (failure dashboard)
+
+**Queue Stuck**:
+- 🚨 **Operator Team** (Slack alert)
+- 📢 **Prism Console** (warning banner)
+
+### Notification Channels
+
+| Event | GitHub | Email | Slack | Prism | Urgency |
+|-------|--------|-------|-------|-------|---------|
+| PR opened | ✅ | ⚠️ | ❌ | ✅ | Low |
+| PR approved | ✅ | ❌ | ❌ | ✅ | Low |

+| Breaking change | ✅ | ✅ | ✅ | ✅ | High |
+
+**Legend**:
+- ✅ Always notify
+- ⚠️ Notify if subscribed/configured
+- ❌ Never notify
+
+---
+
+## Exception Handling
+
+### What Happens When Automation Fails?
+
+#### Auto-Approval Fails
+
+**Causes**:
+- PR does not meet criteria
+- Required checks fail
+- Labels indicate human review needed
+
+**Action**:
+- ⏸️ Pause automation
+- 📌 Add `needs-review` label
+- 📧 Notify CODEOWNERS
+- 🔄 Wait for human approval
+
+#### Auto-Merge Fails
+
+**Causes**:
+- Merge conflicts
+- Queue timeout
+- Checks fail after approval
+- GitHub API error
+
+**Action**:
+- ⏸️ Pause automation
+- 📌 Add `needs-rebase` or `needs-review` label
+- 📧 Notify PR author and reviewers
+- 📊 Log failure in Prism Console
+- 🔄 Wait for human intervention
+
+**Retry Logic**:
+```yaml
+- name: Auto-merge with retry
+  uses: pascalgn/automerge-action@v0.16.2
+  with:
+    github-token: ${{ secrets.GITHUB_TOKEN }}
+    merge-retries: 3
+    merge-retry-sleep: 60000  # 1 minute
+```
+
+#### Queue Gets Stuck
+
+**Causes**:
+- PR takes too long to run checks
+- Circular dependencies
+- Infrastructure outage
+
+**Action**:
+- 🚨 Alert Operator Team
+- 📊 Display warning in Prism Console
+- ⏱️ Wait for timeout (60 minutes default)
+- 🔄 After timeout, remove PR from queue
+- 📧 Notify PR author to investigate
+
+**Manual Override**:
+```bash
+# Remove PR from queue (GitHub CLI)
+gh pr merge <PR_NUMBER> --admin --merge
+```
+
+#### False Positive Auto-Merge
+
+**Scenario**: A PR auto-merged that shouldn't have
+
+**Action**:
+1. 🚨 Operator notices issue
+2. 🔄 Immediately revert merge
+3. 📌 Add `do-not-merge` label to original PR
+4. 📝 Document what went wrong
+5. 🔧 Update automation rules to prevent recurrence
+6. 📧 Notify team about the incident
+
+**Prevention**:
+- Conservative initial rules
+- Gradual expansion of auto-merge categories
+- Regular audits of auto-merged PRs
+- Soak time for AI-generated PRs
+
+---
+
+## Escalation Path
+
+### Level 1: Automation
+
+- Auto-label → Auto-approve → Auto-merge
+- **Duration**: 5-45 minutes
+- **Human involvement**: 0%
+
+### Level 2: Bot Review
+
+- Automation fails a check
+- Bot adds `needs-review` label
+- Bot notifies CODEOWNERS
+- **Duration**: 1-4 hours (human review SLA)
+- **Human involvement**: 10%
+
+### Level 3: Human Review
+
+- Complex PR, breaking change, or security issue
+- Human manually reviews and approves
+- May still auto-merge after approval
+- **Duration**: 4-24 hours
+- **Human involvement**: 50%
+
+### Level 4: Manual Merge
+
+- High-risk change (infra, workflows, CODEOWNERS)
+- Human approves AND manually merges
+- **Duration**: 24-72 hours
+- **Human involvement**: 100%
+
+---
+
+## Audit & Compliance
+
+### Logging
+
+All automation actions are logged:
+- **GitHub**: Pull request timeline (comments, labels, approvals)
+- **Database**: `github_events` table (via Operator)
+- **Prism**: Merge queue dashboard (real-time view)
+
+### Audit Trail
+
+Each auto-merge includes:
+```markdown
+<!-- Auto-Merge Bot Comment -->
+🤖 **Auto-Merge Report**
+
+**Approved By**: docs-bot (automated)
+**Merge Method**: squash
+**Checks Passed**: ✅ Markdown Lint
+**Labels**: docs-only, auto-merge
+**Soak Time**: 0 minutes
+**Merged At**: 2025-11-18 14:32:15 UTC
+
+**Automation Rule**: Tier 1 (Docs-Only)
+**Reference**: GITHUB_AUTOMATION_RULES.md#tier-1-docs-only
+```
+
+### Weekly Review
+
+**Every Monday**:
+- 📊 Review all auto-merged PRs from previous week
+- 📈 Analyze metrics (success rate, failure modes)
+- 🔧 Adjust rules as needed
+- 📝 Document learnings
+
+---
+
+## Summary
+
+**Phase Q Automation Rules** provide a **comprehensive framework** for managing PRs at scale:
+
+- ✅ **5 Tiers of Auto-Approval** (Docs → Tests → Scaffolds → AI → Dependencies)
+- ✅ **Path-Based Workflow Triggers** (Only run relevant CI)
+- ✅ **Intelligent Auto-Merge** (With soak time and safety checks)
+- ✅ **Comprehensive Labeling** (File-based, size-based, author-based)

+# 🌌 MERGE QUEUE PLAN — Phase Q
+
+> **BlackRoad Operating System**
+> **Phase**: Q — Merge Queue & Automation Strategy
+> **Owner**: Operator Alexa (Cadillac)
+> **Status**: Implementation Ready
+> **Last Updated**: 2025-11-18
+
+---
+
+## Executive Summary
+
+Phase Q transforms the BlackRoad GitHub organization from a **merge bottleneck** into a **flowing automation pipeline** capable of handling 50+ concurrent PRs from AI agents, human developers, and automated systems.
+
+This plan implements:
+- ✅ **Merge Queue System** — Race-condition-free sequential merging
+- ✅ **Auto-Merge Logic** — Zero-touch merging for safe PR categories
+- ✅ **Workflow Bucketing** — Module-specific CI to reduce build times
+- ✅ **Smart Labeling** — Automatic categorization and routing
+- ✅ **CODEOWNERS v2** — Module-based ownership with automation awareness
+- ✅ **Operator Integration** — PR events flowing into the OS
+- ✅ **Prism Dashboard** — Real-time queue visualization
+
+---
+
+## Problem Statement
+
+### Current Pain Points
+
+**Before Phase Q**:
+```
+50+ PRs waiting → Manual reviews → CI conflicts → Stale branches → Wasted time
+```
+
+**Issues**:
+1. **Race conditions** — Merges invalidate each other's tests
+2. **Stale branches** — PRs fall behind main rapidly
+3. **CI congestion** — All workflows run on every PR
+4. **Manual overhead** — Humans gate trivial PRs
+5. **Context switching** — Operators lose flow state
+6. **No visibility** — Queue status is opaque
+
+### After Phase Q
+
+```
+PR created → Auto-labeled → Queued → Tests run → Auto-merged → Operator notified
+```
+
+**Outcomes**:
+- ⚡ **10x throughput** — Handle 50+ PRs/day
+- 🤖 **90% automation** — Only complex PRs need human review
+- 🎯 **Zero conflicts** — Queue manages sequential merging
+- 📊 **Full visibility** — Prism dashboard shows queue state
+- 🚀 **Fast CI** — Only affected modules run tests
+- 🧠 **Operator-aware** — GitHub events feed into BlackRoad OS

+## Merge Queue Configuration
+
+### What is a Merge Queue?
+
+A **merge queue** is GitHub's solution to the "stale PR" problem:
+
+**Traditional Workflow**:
+1. PR #1 passes tests on branch `feature-a`
+2. PR #1 merges to `main`
+3. PR #2 (based on old `main`) is now stale
+4. PR #2 must rebase and re-run tests
+5. Repeat for every PR → exponential waiting
+
+**Merge Queue Workflow**:
+1. Approved PRs enter a queue
+2. GitHub creates temporary merge commits
+3. Tests run on the *merged state*
+4. Only green PRs merge sequentially
+5. No stale branches, no race conditions
+
+### Queue Rules
+
+**Merge Queue Settings** (`.github/merge_queue.yml`):
+
+```yaml
+merge_method: squash           # or merge, rebase
+merge_commit_message: PR_TITLE
+merge_commit_title_pattern: "[%number%] %title%"
+
+# Required status checks (must pass before entering queue)
+required_checks:
+  - Backend Tests
+  - Frontend Validation
+  - Security Scan
+
+# Queue behavior
+min_entries_to_merge: 0        # Merge immediately when ready
+max_entries_to_merge: 5        # Merge up to 5 PRs at once
+merge_timeout_minutes: 60      # Fail if stuck for 1 hour
+
+# Branch update method
+update_method: rebase          # Keep clean history
+```
+
+**Branch Protection Rules** (applied via GitHub UI):
+- ✅ Require pull request before merging
+- ✅ Require status checks to pass
+- ✅ Require branches to be up to date
+- ✅ Require merge queue
+- ✅ Do not allow bypassing (even admins)
+
+---
+
+## Auto-Merge Policy
+
+See `AUTO_MERGE_POLICY.md` for full details.
+
+### Safe-to-Merge Categories
+
+| Category | Auto-Approve | Auto-Merge | Rationale |
+|----------|--------------|------------|-----------|
+| **Docs-only** | ✅ | ✅ | No code changes, low risk |
+| **Tests-only** | ✅ | ✅ | Improves coverage, no prod impact |
+| **Scaffold/Stubs** | ✅ | ✅ | Template code, reviewed later |
+| **CI/Workflow updates** | ✅ | ⚠️ Manual | High impact, human check |
+| **Dependency bumps** | ⚠️ Dependabot | ⚠️ Manual | Security check required |
+| **Chore (formatting, etc.)** | ✅ | ✅ | Linters enforce standards |
+| **Claude-generated** | ✅ (if tests pass) | ✅ | AI-authored, tests validate |
+| **Breaking changes** | ❌ | ❌ | Always human review |
+| **Security fixes** | ❌ | ❌ | Always human review |
+
+### Auto-Merge Triggers
+
+A PR auto-merges if:
+1. ✅ Has label: `auto-merge` OR `claude-auto` OR `docs-only`
+2. ✅ All required checks pass
+3. ✅ At least one approval (can be bot)
+4. ✅ No `breaking-change` or `security` labels
+5. ✅ Branch is up to date (or in merge queue)
+
+**Implementation**:
+```yaml
+# .github/auto-merge.yml
+name: Auto-Merge
+on:
+  pull_request_review:
+    types: [submitted]
+  status: {}
+
+jobs:
+  auto-merge:
+    if: |
+      github.event.review.state == 'approved' &&
+      contains(github.event.pull_request.labels.*.name, 'auto-merge')
+    runs-on: ubuntu-latest
+    steps:
+      - uses: pascalgn/automerge-action@v0.16.2
+        env:
+          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+          MERGE_LABELS: auto-merge,claude-auto,docs-only
+          MERGE_METHOD: squash
+```
+
+---
+
+## Workflow Bucketing
+
+### Problem
+
+**Before**:
+- Every PR triggers all CI workflows
+- Backend changes run frontend tests
+- Docs changes run full test suite
+- Result: Wasted CI minutes, slow feedback
+
+### Solution
+
+**Module-Specific Workflows**:
+
+| Workflow | Trigger Paths | Jobs |
+|----------|---------------|------|
+| `backend-ci.yml` | `backend/**`, `requirements.txt` | pytest, type check, lint |
+| `frontend-ci.yml` | `blackroad-os/**`, `backend/static/**` | HTML validation, JS syntax |
+| `agents-ci.yml` | `agents/**` | Agent tests, template validation |
+| `docs-ci.yml` | `docs/**`, `*.md` | Markdown lint, link check |
+| `infra-ci.yml` | `infra/**`, `.github/**`, `ops/**` | Config validation, Terraform plan |
+| `sdk-ci.yml` | `sdk/**` | Python SDK tests, TypeScript build |
+
+**Example** (`backend-ci.yml`):
+```yaml
+name: Backend CI
+on:
+  pull_request:
+    paths:
+      - 'backend/**'
+      - 'requirements.txt'
+      - 'Dockerfile'
+  push:
+    branches: [main]
+    paths:
+      - 'backend/**'
+
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - uses: actions/setup-python@v5
+        with:
+          python-version: '3.11'
+      - name: Install dependencies
+        run: |
+          cd backend
+          pip install -r requirements.txt
+      - name: Run tests
+        run: |
+          cd backend
+          pytest -v --cov
+```
+
+**Benefits**:
+- ⚡ **3-5x faster** CI for most PRs
+- 💰 **60% cost reduction** in CI minutes
+- 🎯 **Targeted feedback** — Only relevant tests run
+- 🔄 **Parallel execution** — Multiple workflows run simultaneously
+
+---
+
+## Labeling Strategy
+
+### Auto-Labeling
+
+**Configuration** (`.github/labeler.yml`):
+```yaml
+# Documentation
+docs:
+  - changed-files:
+    - any-glob-to-any-file: ['docs/**/*', '*.md', 'README.*']
+
+# Backend
+backend:

+
+# Infrastructure
+infra:
+  - changed-files:
+    - any-glob-to-any-file: ['.github/**/*', 'infra/**/*', 'ops/**/*', '*.toml', '*.json']
+
+# Agents
+agents:
+  - changed-files:
+    - any-glob-to-any-file: 'agents/**/*'
+
+# Tests
+tests:
+  - changed-files:
+    - any-glob-to-any-file: ['**/tests/**/*', '**/*test*.py', '**/*.test.js']
+
+# Dependencies
+dependencies:
+  - changed-files:
+    - any-glob-to-any-file: ['requirements.txt', 'package*.json', 'Pipfile*']
+```
+
+### Manual Labels
+
+Applied by humans or bots:
+
+| Label | Purpose | Auto-Merge? |
+|-------|---------|-------------|
+| `claude-auto` | Claude-generated PR | ✅ (if tests pass) |
+| `atlas-auto` | Atlas-generated PR | ✅ (if tests pass) |
+| `merge-ready` | Human approved, safe to merge | ✅ |
+| `needs-review` | Requires human eyes | ❌ |
+| `breaking-change` | API or behavior change | ❌ |
+| `security` | Security-related change | ❌ |
+| `critical` | Urgent fix, prioritize | ⚠️ Human decides |
+| `wip` | Work in progress, do not merge | ❌ |

+
+## Operator Integration
+
+### GitHub Event Handler
+
+**Location**: `backend/app/services/github_events.py`
+
+**Functionality**:
+- Receives GitHub webhook events
+- Filters for PR events (opened, merged, closed, labeled)
+- Logs to database (`github_events` table)
+- Emits events to Operator Engine
+- Notifies Prism Console for dashboard updates
+
+**Event Flow**:
+```
+GitHub Webhook → FastAPI Endpoint → Event Handler → Database + Operator → Prism UI
+```
+
+**Example Events**:
+- `pr.opened` → Show notification in OS
+- `pr.merged` → Update team metrics
+- `pr.failed_checks` → Alert Operator
+- `pr.queue_entered` → Update dashboard
+
+---
+
+## Prism Dashboard
+
+### Merge Queue Visualizer
+
+**Location**: `blackroad-os/js/apps/prism-merge-dashboard.js`
+
+**Features**:
+- Real-time queue status
+- PR list with labels, checks, ETA
+- Throughput metrics (PRs/day, avg time-to-merge)
+- Failure analysis (which checks fail most)
+- Operator actions (approve, merge, close)
+
+**UI Mockup**:
+```

+## Risk Mitigation
+
+### Identified Risks
+
+| Risk | Impact | Likelihood | Mitigation |
+|------|--------|------------|------------|
+| **Queue gets stuck** | High | Medium | Timeout + manual override |
+| **False auto-merges** | High | Low | Conservative initial policy |
+| **CI failures increase** | Medium | Medium | Gradual rollout, monitor closely |
+| **Operator overload** | Low | Medium | Rate limiting on webhooks |
+| **Breaking changes slip through** | High | Low | Required `breaking-change` label |
+
+### Rollback Plan
+
+If Phase Q causes issues:
+1. **Disable merge queue** (GitHub UI → branch protection)
+2. **Disable auto-merge** (pause workflow)
+3. **Revert to manual approval** (CODEOWNERS update)
+4. **Keep bucketed workflows** (they're strictly better)
+5. **Investigate and fix** before re-enabling
+
+**Rollback Time**: <5 minutes
+
+---
+
+## Maintenance & Evolution
+
+### Regular Tasks
+
+**Daily**:
+- Check Prism dashboard for queue anomalies
+- Review auto-merged PRs (spot check)
+
+**Weekly**:
+- Analyze throughput metrics
+- Identify slowest CI checks
+- Update labeler patterns as needed
+
+**Monthly**:
+- Review auto-merge policy
+- Adjust CODEOWNERS for new modules
+- Optimize workflow bucket paths
+- Audit GitHub Actions usage
+
+### Future Enhancements
+
+**Phase Q.7 — Multi-Repo Queues**:
+- Coordinate merges across blackroad-api, blackroad-operator, etc.
+- Prevent dependency conflicts
+
+**Phase Q.8 — AI-Powered Triage**:
+- Lucidia agents auto-review PRs
+- Suggest reviewers based on code changes
+- Predict merge time
+
+**Phase Q.9 — Merge Forecasting**:
+- ML model predicts queue wait time
+- Alerts Operators about upcoming bottlenecks
+- Recommends workflow optimizations
+
+---
+
+## Conclusion
+
+Phase Q transforms GitHub from a manual, bottleneck-prone system into an **automated merge pipeline** that scales with your AI-powered development velocity.
+
+By combining **merge queues**, **auto-merge logic**, **workflow bucketing**, and **Operator integration**, we achieve:
+
+- ✅ **10x throughput** without sacrificing quality
+- ✅ **90% automation** for safe PR categories
+- ✅ **Full visibility** via Prism Dashboard
+- ✅ **Zero conflicts** through queue management
+- ✅ **Fast feedback** via targeted CI
+
+This is the foundation for a **self-governing engineering organization** where AI and humans collaborate seamlessly.
+

+## Webhook Configuration
+
+### GitHub Setup
+
+**Location**: Repository Settings → Webhooks → Add webhook
+
+**Configuration**:
+- **Payload URL**: `https://blackroad.app/api/webhooks/github`
+- **Content type**: `application/json`
+- **Secret**: (set in GitHub, store in env as `GITHUB_WEBHOOK_SECRET`)
+- **Events**: Select individual events:
+  - Pull requests
+  - Pull request reviews
+  - Pull request review comments
+  - Statuses
+  - Check runs
+  - Check suites
+
+**Security**:
+- GitHub signs payloads with HMAC-SHA256
+- FastAPI validates signature before processing
+- Rejects unsigned or invalid webhooks

+        case 'github:pr_entered_queue':
+            onPREnteredQueue(message.data);
+            break;
+        case 'github:pr_check_completed':
+            onCheckCompleted(message.data);
+            break;

+};
+
+function onPROpened(data) {
+    console.log(`PR #${data.pr_number} opened: ${data.title}`);
+    // Update dashboard UI
+}
+
+function onPREnteredQueue(data) {
+    console.log(`PR #${data.pr_number} entered queue at position ${data.position}`);
+    // Update queue visualization
+}
+```

+
+## Operator Engine Integration
+
+### OS-Level Events
+
+**Operator Engine** can react to GitHub events:
+
+```python
+# Example: backend/app/services/operator_engine.py
+
+from typing import Callable, Dict, Any
+
+class OperatorEngine:
+    """BlackRoad Operator Engine"""
+
+    def __init__(self):
+        self.event_handlers: Dict[str, list[Callable]] = {}
+
+    def on(self, event_name: str, handler: Callable):
+        """Register event handler"""
+        if event_name not in self.event_handlers:
+            self.event_handlers[event_name] = []
+        self.event_handlers[event_name].append(handler)
+
+    def emit(self, event_name: str, data: Dict[str, Any]):
+        """Emit event to all registered handlers"""
+        handlers = self.event_handlers.get(event_name, [])
+        for handler in handlers:
+            handler(data)
+
+# Global operator instance
+operator = OperatorEngine()
+
+# Register GitHub event handlers
+operator.on('github:pr:opened', lambda data: print(f"PR opened: {data}"))
+operator.on('github:pr:merged', lambda data: print(f"PR merged: {data}"))
+```
+
+---
+
+## Automation Rules
+
+### Auto-Labeling on PR Open
+
+```python
+async def on_pr_opened(pr_data: Dict[str, Any], db: AsyncSession):
+    """Auto-label PR based on files changed"""
+
+    # Get changed files
+    files_changed = await get_pr_files(pr_data["number"])
+
+    # Determine labels
+    labels = []
+
+    if all(f.startswith("docs/") or f.endswith(".md") for f in files_changed):
+        labels.append("docs-only")
+
+    if all(f.startswith("backend/tests/") for f in files_changed):
+        labels.append("tests-only")
+
+    if pr_data["head"]["ref"].startswith("claude/"):
+        labels.append("claude-auto")
+
+    # Apply labels
+    if labels:
+        await apply_labels(pr_data["number"], labels)
+```

+# ⚡ WORKFLOW BUCKETING EXPLAINED
+
+> **BlackRoad Operating System — Phase Q**
+> **Purpose**: Module-specific CI for faster, cheaper builds
+> **Owner**: Operator Alexa (Cadillac)
+> **Last Updated**: 2025-11-18
+
+---
+
+## What is Workflow Bucketing?
+
+**Workflow Bucketing** is the practice of splitting a monolithic CI pipeline into **module-specific workflows** that only run when relevant files change.
+
+### Before Bucketing (Monolithic CI)
+
+```yaml
+# .github/workflows/ci.yml
+name: CI
+on: [pull_request]
+
+jobs:
+  test-everything:
+    runs-on: ubuntu-latest
+    steps:
+      - Backend tests (5 min)
+      - Frontend tests (3 min)
+      - Agent tests (2 min)
+      - Docs linting (1 min)
+      - Infra validation (2 min)
+      # Total: 13 minutes PER PR
+```
+
+**Problems**:
+- 📝 Docs-only PR runs backend tests (unnecessary)
+- 🎨 Frontend PR runs agent tests (waste of time)
+- 💰 Every PR costs 13 CI minutes (expensive)
+- ⏱️ Slow feedback (wait for irrelevant tests)
+
+### After Bucketing (Module-Specific CI)
+
+```yaml
+# .github/workflows/backend-ci.yml
+name: Backend CI
+on:
+  pull_request:
+    paths: ['backend/**']  # Only run when backend changes
+
+jobs:
+  test-backend:
+    runs-on: ubuntu-latest
+    steps:
+      - Backend tests (5 min)
+      # Total: 5 minutes for backend PRs
+```
+
+```yaml
+# .github/workflows/docs-ci.yml
+name: Docs CI
+on:
+  pull_request:
+    paths: ['docs/**', '*.md']  # Only run when docs change
+
+jobs:
+  lint-docs:
+    runs-on: ubuntu-latest
+    steps:
+      - Docs linting (1 min)
+      # Total: 1 minute for docs PRs
+```
+
+**Benefits**:
+- ⚡ **3-5x faster** CI (only relevant tests run)
+- 💰 **60% cost reduction** (fewer wasted minutes)
+- 🎯 **Targeted feedback** (see relevant results first)
+- 🔄 **Parallel execution** (multiple buckets run simultaneously)

+
+---
+
+## Path-Based Triggering
+
+### How it Works
+
+GitHub Actions supports path filtering:
+
+```yaml
+on:
+  pull_request:
+    paths:
+      - 'backend/**'           # All files in backend/
+      - '!backend/README.md'   # Except backend README
+      - 'requirements.txt'     # Specific file
+      - '**/*.py'              # All Python files anywhere
+```
+
+**Operators**:
+- `**` — Match any number of directories
+- `*` — Match any characters except `/`
+- `!` — Negation (exclude pattern)
+
+### Path Patterns by Bucket
+
+**Backend**:
+```yaml
+paths:
+  - 'backend/**'
+  - 'requirements.txt'
+  - 'Dockerfile'
+  - 'docker-compose.yml'
+```
+
+**Frontend**:
+```yaml
+paths:
+  - 'blackroad-os/**'
+  - 'backend/static/**'
+```
+
+**Agents**:
+```yaml
+paths:
+  - 'agents/**'
+```
+
+**Docs**:
+```yaml
+paths:
+  - 'docs/**'
+  - '*.md'
+  - 'README.*'
+  - '!backend/README.md'  # Exclude backend README (triggers backend CI)
+```
+
+**Infrastructure**:
+```yaml
+paths:
+  - 'infra/**'
+  - 'ops/**'
+  - '.github/**'
+  - '*.toml'
+  - '*.json'
+  - '!package.json'  # Exclude package.json (triggers SDK CI)
+```
+
+**SDK**:
+```yaml
+paths:
+  - 'sdk/python/**'
+  - 'sdk/typescript/**'
+```
+
+---
+
+## Multi-Module PRs
+
+### What if a PR changes multiple modules?
+
+**Example**: PR changes both backend and frontend
+
+**Result**: Both workflows run
+
+```
+PR #123: Add user profile page
+- backend/app/routers/profile.py
+- blackroad-os/js/apps/profile.js
+
+Workflows triggered:
+✅ backend-ci.yml (5 min)
+✅ frontend-ci.yml (3 min)
+Total: 8 min (runs in parallel)
+```
+
+**Without bucketing**:
+- Would run 13-minute monolithic CI
+- Savings: 5 minutes (38% faster)
+
+### Overlapping Changes
+
+**Example**: PR changes docs in backend README
+
+```
+PR #124: Update backend README
+- backend/README.md
+
+Workflows triggered:
+✅ backend-ci.yml (backend/** matches)
+✅ docs-ci.yml (*.md matches)
+```
+
+**Solution**: Use negation to exclude overlaps
+
+```yaml
+# docs-ci.yml
+paths:
+  - 'docs/**'
+  - '*.md'
+  - '!backend/README.md'  # Let backend CI handle this
+  - '!sdk/python/README.md'  # Let SDK CI handle this
+```
+
+**Result**: Only `backend-ci.yml` runs
+
+---
+
+## Cost Savings Analysis
+
+### Assumptions
+
+- **PRs per day**: 50
+- **Distribution**:
+  - 30% docs-only
+  - 20% backend-only
+  - 15% frontend-only
+  - 10% agents-only
+  - 10% infra-only
+  - 15% multi-module
+
+### Before Bucketing
+
+| PR Type | Count | CI Time | Total Time |
+|---------|-------|---------|------------|
+| Docs | 15 | 13 min | 195 min |
+| Backend | 10 | 13 min | 130 min |
+| Frontend | 7.5 | 13 min | 97.5 min |
+| Agents | 5 | 13 min | 65 min |
+| Infra | 5 | 13 min | 65 min |
+| Multi | 7.5 | 13 min | 97.5 min |
+| **Total** | **50** | — | **650 min/day** |
+
+**Monthly cost**: 650 min/day × 30 days = **19,500 minutes**
+
+### After Bucketing
+
+| PR Type | Count | CI Time | Total Time |
+|---------|-------|---------|------------|
+| Docs | 15 | 1 min | 15 min |
+| Backend | 10 | 5 min | 50 min |
+| Frontend | 7.5 | 3 min | 22.5 min |
+| Agents | 5 | 2 min | 10 min |
+| Infra | 5 | 2 min | 10 min |
+| Multi | 7.5 | 8 min | 60 min |
+| **Total** | **50** | — | **167.5 min/day** |
+
+**Monthly cost**: 167.5 min/day × 30 days = **5,025 minutes**
+
+**Savings**: 19,500 - 5,025 = **14,475 minutes/month** (74% reduction)
+
+**Dollar Savings** (at $0.008/min for GitHub Actions):
+- Before: $156/month
+- After: $40/month
+- **Savings: $116/month**
+
+---
+
+## Implementation Best Practices
+
+### 1. Overlapping Paths
+
+**Problem**: Some paths trigger multiple workflows
+
+**Solution**: Use negation to assign ownership
+
+```yaml
+# docs-ci.yml - Only general docs
+paths:
+  - 'docs/**'
+  - '*.md'
+  - '!backend/**/*.md'
+  - '!sdk/**/*.md'
+
+# backend-ci.yml - Backend + backend docs
+paths:
+  - 'backend/**'  # Includes backend/**/*.md
+```
+
+### 2. Shared Dependencies
+
+**Problem**: `requirements.txt` affects backend, agents, SDK
+
+**Solution**: Trigger all affected buckets
+
+```yaml
+# backend-ci.yml
+paths:
+  - 'backend/**'
+  - 'requirements.txt'
+
+# agents-ci.yml
+paths:
+  - 'agents/**'
+  - 'requirements.txt'
+
+# sdk-ci.yml
+paths:
+  - 'sdk/python/**'
+  - 'requirements.txt'
+```
+
+### 3. Global Files
+
+**Problem**: `.gitignore`, `LICENSE`, `.env.example` don't fit in buckets
+
+**Solution**: Create a separate "meta" workflow (or skip CI)
+
+```yaml
+# meta-ci.yml (optional)
+on:
+  pull_request:
+    paths:
+      - '.gitignore'
+      - 'LICENSE'
+      - '.env.example'
+
+jobs:
+  validate-meta:
+    runs-on: ubuntu-latest
+    steps:
+      - name: Validate .env.example
+        run: python scripts/validate_env.py
+```
+
+**Alternative**: Docs-only changes (like LICENSE) can skip CI entirely
+
+### 4. Required Checks
+
+**Problem**: Branch protection requires specific check names
+
+**Solution**: Make bucket names consistent
+
+```yaml
+# backend-ci.yml
+jobs:
+  test:  # Always call it 'test'
+    name: Backend Tests  # Display name
+
+# frontend-ci.yml
+jobs:
+  test:  # Same job name
+    name: Frontend Tests  # Different display name
+```
+
+**Branch protection**:
+```
+Required status checks:
+- Backend Tests
+- Frontend Tests
+- Security Scan
+```
+
+**Smart behavior**: Only require checks that ran (based on paths)
+
+---
+
+## Parallel Execution
+
+### How Parallelism Works
+
+GitHub Actions runs workflows **in parallel** by default.
+
+**Example**: PR changes backend + frontend
+
+```
+PR opened at 14:00:00
+├─> backend-ci.yml starts at 14:00:05 (5 min duration)
+└─> frontend-ci.yml starts at 14:00:06 (3 min duration)
+
+Both finish by 14:05:06 (5 min total wall time)
+```
+
+**Without parallelism**: 5 min + 3 min = 8 min
+
+**With parallelism**: max(5 min, 3 min) = 5 min
+
+**Time savings**: 37.5%
+
+### Matrix Strategies
+
+For even more parallelism:
+
+```yaml
+# backend-ci.yml
+jobs:
+  test:
+    strategy:
+      matrix:
+        python-version: ['3.10', '3.11', '3.12']
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/setup-python@v5
+        with:
+          python-version: ${{ matrix.python-version }}
+      - run: pytest
+```
+
+**Result**: 3 jobs run in parallel (Python 3.10, 3.11, 3.12)
+
+---
+
+## Monitoring & Metrics
+
+### Track Workflow Performance
+
+**Metrics to monitor**:
+- Average CI time per bucket
+- Failure rate per bucket
+- Cost per bucket (CI minutes used)
+- Coverage of path patterns (any PRs skipping CI?)
+
+**Tools**:
+- GitHub Actions usage reports
+- Prism Console metrics dashboard
+- Custom analytics (log workflow runs to database)
+
+### Optimize Slow Buckets
+
+**If backend-ci.yml is slow (> 10 min)**:
+- Split into smaller jobs (lint, test, type-check in parallel)
+- Cache dependencies aggressively
+- Use matrix to parallelize tests
+- Remove redundant checks
+
+**Example**:
+```yaml
+# Before: Sequential (10 min total)
+jobs:
+  test-backend:
+    steps:
+      - Install deps (2 min)
+      - Lint (2 min)
+      - Type check (2 min)
+      - Tests (4 min)
+
+# After: Parallel (4 min total)
+jobs:
+  lint:
+    steps:
+      - Install deps (2 min)
+      - Lint (2 min)
+  type-check:
+    steps:
+      - Install deps (2 min)
+      - Type check (2 min)
+  test:
+    steps:
+      - Install deps (2 min)
+      - Tests (4 min)
+```
+
+---
+
+## Migration from Monolithic CI
+
+### Step 1: Analyze Current CI
+
+**Questions**:
+- Which tests take longest?
+- Which tests fail most often?
+- What are logical module boundaries?
+
+### Step 2: Create Buckets
+
+Start with obvious buckets:
+- Backend
+- Frontend
+- Docs
+
+### Step 3: Run in Parallel (Validation)
+
+Run both monolithic CI and bucketed CI:
+
+```yaml
+# ci.yml (keep existing)
+name: CI (Legacy)
+on: [pull_request]
+
+# backend-ci.yml (new)
+name: Backend CI
+on:
+  pull_request:
+    paths: ['backend/**']
+```
+
+**Compare results**:
+- Do both pass/fail consistently?
+- Is bucketed CI faster?
+- Are there gaps (PRs that skip CI)?
+
+### Step 4: Migrate Branch Protection
+
+Update required checks:
+
+```
+Before:
+- CI (Legacy)
+
+After:
+- Backend Tests
+- Frontend Tests
+- Docs Lint
+```
+
+### Step 5: Remove Monolithic CI
+
+Once confident, delete `ci.yml`
+
+---
+
+## Summary
+
+**Workflow Bucketing** achieves:
+
+- ⚡ **3-5x faster CI** (only relevant tests run)
+- 💰 **74% cost reduction** (fewer CI minutes)
+- 🎯 **Targeted feedback** (see results faster)
+- 🔄 **Parallel execution** (multiple buckets simultaneously)
+- 📊 **Better metrics** (per-module failure rates)
+
+**Implementation**:
+- Define module boundaries (backend, frontend, agents, docs, infra, SDK)
+- Create workflow per module with path filters
+- Handle overlaps with negation
+- Monitor and optimize slow buckets
+
+**Result**: **Faster, cheaper, smarter CI pipeline**

+
+## Event Flow Sequences
+
+### Sequence 1: PR Opened
+
+1. **GitHub**: User opens PR
+2. **GitHub**: Sends webhook to `/api/webhooks/github`
+3. **FastAPI**: Validates signature, parses event
+4. **Event Handler**: Calls `handle_pull_request()`
+5. **Event Handler**: Calls `on_pr_opened(pr_data)`
+6. **Database**: Inserts row in `pull_requests` table
+7. **Event Handler**: Calls `emit_os_event("github:pr:opened")`
+8. **Event Handler**: Calls `notify_prism("pr_opened")`
+9. **Prism Console**: Receives WebSocket message
+10. **Prism Console**: Updates dashboard UI
+11. **Operator Engine**: Receives OS event
+12. **Operator Engine**: Logs to operator dashboard
+
+### Sequence 2: PR Approved → Auto-Merge
+
+1. **GitHub**: Reviewer approves PR
+2. **GitHub**: Sends `pull_request_review` webhook
+3. **FastAPI**: Routes to `handle_pr_review()`
+4. **Event Handler**: Checks if `state == "approved"`
+5. **Database**: Updates `pull_requests.approved = true`
+6. **Event Handler**: Calls `check_merge_queue_eligibility()`
+7. **Event Handler**: Checks:
+   - Has auto-merge label? ✅
+   - Approved? ✅
+   - All checks pass? ✅
+   - No conflicts? ✅
+8. **Database**: Inserts row in `merge_queue` table
+9. **Event Handler**: Calls `notify_prism("pr_entered_queue")`
+10. **Prism Console**: Shows "PR entered queue" notification
+11. **GitHub Actions**: Auto-merge workflow triggers
+12. **GitHub Actions**: Waits soak time (5 min for AI PRs)
+13. **GitHub Actions**: Merges PR
+14. **GitHub**: Sends `pull_request` (action: closed, merged: true)
+15. **Event Handler**: Calls `on_pr_closed()` with `merged=true`
+16. **Database**: Updates `pull_requests.merged_at`
+17. **Database**: Updates `merge_queue.status = "completed"`
+18. **Prism Console**: Shows "PR merged" notification
+19. **Prism Console**: Removes PR from queue UI
+
+### Sequence 3: Check Run Completed
+
+1. **GitHub**: CI check completes
+2. **GitHub**: Sends `check_run` webhook
+3. **FastAPI**: Routes to `handle_check_run()`
+4. **Event Handler**: Extracts `conclusion` (success/failure)
+5. **Event Handler**: Finds associated PRs
+6. **Database**: Updates `pull_requests.checks` JSON field
+7. **Event Handler**: If all checks pass:
+   - Calls `check_merge_queue_eligibility()`
+8. **Event Handler**: Calls `notify_prism("pr_check_completed")`
+9. **Prism Console**: Updates check status in UI
+10. **Operator Engine**: Logs check result

+    completed_at TIMESTAMP,
+    error_message TEXT,
+    FOREIGN KEY (pr_number) REFERENCES pull_requests(number)
+);
+```
+
+---
+
+## WebSocket Protocol
+
+### Client → Server (Subscribe)
+
+```json
+{
+  "type": "subscribe",
+  "channel": "github:events"
+}
+```
+
+### Server → Client (Event)
+
+```json
+{
+  "type": "github:pr_opened",
+  "data": {
+    "pr_number": 123,
+    "title": "Add user authentication",
+    "author": "claude-code[bot]",
+    "url": "https://github.com/.../pull/123"
+  },
+  "timestamp": "2025-11-18T14:32:15Z"
+}
+```
+
+### Event Types
+
+- `github:pr_opened`
+- `github:pr_approved`
+- `github:pr_entered_queue`
+- `github:pr_check_completed`
+- `github:pr_closed`
+- `github:pr_updated`
+- `github:pr_auto_merge_enabled`
+
+---
+
+## Security
+
+### Webhook Signature Validation
+
+```python
+import hmac
+import hashlib
+
+def validate_signature(payload_body: bytes, signature: str, secret: str) -> bool:
+    expected_signature = "sha256=" + hmac.new(
+        secret.encode(),
+        payload_body,
+        hashlib.sha256
+    ).hexdigest()
+
+    return hmac.compare_digest(signature, expected_signature)
+```
+
+### Required Headers
+
+- `X-Hub-Signature-256`: HMAC-SHA256 signature
+- `X-GitHub-Event`: Event type (e.g., "pull_request")
+- `X-GitHub-Delivery`: Unique delivery ID
+- `Content-Type`: `application/json`
+
+---
+
+## API Endpoints
+
+### Webhook Endpoint
+
+```
+POST /api/webhooks/github
+Authorization: None (validates signature instead)
+Content-Type: application/json
+X-Hub-Signature-256: sha256=<signature>
+X-GitHub-Event: <event_type>
+
+Body: GitHub webhook payload
+```
+
+### Query Endpoints
+
+```
+GET /api/github/merge-queue
+Returns current queue state
+
+GET /api/github/metrics
+Returns merge metrics (PRs/day, avg time, etc.)
+
+GET /api/github/events?pr_number=123
+Returns event history for PR #123
+```
+
+---
+
+## Monitoring
+
+### Metrics to Track
+
+- **Events received per hour**
+- **Event processing time**
+- **WebSocket connection count**
+- **Database query performance**
+- **Queue depth over time**
+- **Merge success rate**
+
+### Alerting
+
+- Alert if event processing time > 5 seconds
+- Alert if queue depth > 20 PRs
+- Alert if WebSocket disconnects frequently
+- Alert if database writes fail
+
