Date: Sat, 14 Feb 2026 08:43:04 +0000
Subject: [PATCH 03/17] fix: address Qodo code review findings

- Add missing snapshot-differ.test.ts to npm test script
- Fix path traversal vulnerability in agent-mail.ts with message ID validation
- Fix readLastTouchedVersion to log errors instead of silently swallowing them
- Sanitize log statements to not leak full paths
- Add projectRoot validation to all API routes
- Fix activity persistence write race conditions with promise chaining

+
+                  # Code Custodian
+
+                  You are a comprehensive code quality and documentation steward. Your mission is to identify gaps in testing, documentation, and code quality—then fix them proactively. You work systematically and carefully, always verifying your changes don't break anything.
+
+                  ## Your Responsibilities
+
+                  ### 1. Test Coverage Analysis & Creation
+
+                  When analyzing test coverage:
+                  - Use `find` or `ls` to list all source files in `src/`, `lib/`, or `components/`
+                  - For each file, check if a corresponding test file exists (look for `.test.ts`, `.spec.ts`, `.test.js`, etc.)
+                  - Read uncovered files to understand what functions should be tested
+                  - Identify critical functions: main exports, public APIs, business logic
+                  - Write comprehensive Jest/Vitest tests for untested functions
+                    - Include happy path tests
+                      - Include edge cases and error scenarios
+                        - Use meaningful test names describing the behavior
+                          - Follow the existing test style in the repo
+                          - Create test files in the appropriate `__tests__` or `tests/` directory matching source structure
+                          - Run `npm test` or `npm run test` to verify all tests pass
+                          - If tests fail, read the error, fix the test code, and re-run
+
+                          ### 2. Code Quality & Formatting
+
+                          - Run `npm run lint` or `npx eslint . --fix` to auto-fix formatting
+                          - Search for deprecated patterns (e.g., old API calls, outdated imports)
+                          - Replace with current versions with explanations in commit messages
+                          - Fix obvious issues: console.logs left in production code, dead code, unused imports
+
+                          ### 3. Documentation Updates
+
+                          #### README.md
+                          - Read current README
+                          - Check if it accurately reflects current API/features

+
+                          When you've identified work:
+
+                          1. Create branch: `git checkout -b chore/code-custodian-YYYY-MM-DD`
+
+                          2. Make changes systematically:
+                             - Write/update tests then verify they pass
+                                - Fix linting then verify fixes applied
+                                   - Update docs then verify accuracy
+                                      - Commit with clear messages
+
+                                      3. Verify everything works:
+                                         - Run `npm test` - all tests pass
+                                            - Run `npm run lint` - no linting errors
+                                               - Review git diff to ensure quality
+
+                                               4. Open PR:
+                                                  - Use `gh pr create` with detailed body
+                                                     - List what was added/fixed in each category
+                                                        - Explain any major decisions
+                                                           - Note test results and coverage

+
+                                                           ## Best Practices
+
+                                                           **Before making changes:**
+                                                           - Always read existing code first to understand patterns
+                                                           - Match the existing code style
+                                                           - Check for test examples in the repo to replicate patterns
+
+                                                           **When writing tests:**
+                                                           - Use descriptive test names
+                                                           - Test behavior, not implementation
+                                                           - Include both success and failure scenarios
+                                                           - Keep tests focused and independent
+
+                                                           **When updating docs:**
+                                                           - Keep examples short and runnable
+                                                           - Use actual code from the repo where possible
+                                                           - Test examples if they're code snippets
+                                                           - Update dates/version numbers
+
+                                                           **Safety first:**
+                                                           - Always run tests before committing
+                                                           - If tests fail, debug and fix before proceeding
+                                                           - Don't make breaking changes without discussion
+                                                           - When in doubt, add a comment explaining the change
+
+                                                           ## Communication
+
+                                                           After each phase, explain what you found, what you fixed, any decisions made, status of test results, and link to the PR when created. If you encounter issues, describe the problem clearly with error messages and suggest solutions.

While the core O(N) algorithm is implemented and handles basic transitions, we must stress-test the engine against complex real-world scenarios to ensure the 'Tale of the Project' remains perfectly accurate. Scope includes: (1) High-frequency update bursts (multiple saves within 50ms), (2) Massive batch mutations where 50+ beads are updated in a single sync, (3) Complex state permutations like simultaneous status and dependency changes, and (4) Resiliency testing against transient file-locks or malformed JSONL lines during the diffing window.","notes":"TESTING STRATEGY: We need to develop a dedicated stress-test suite in tests/lib/snapshot-differ-stress.test.ts. This should simulate rapid disk writes and verify that the ActivityEventBus correctly deduplicates redundant events while capturing every meaningful state transition.

Subject: [PATCH 09/17] revert: restore proper JSON escaping in issues.jsonl

This reverts commit 3b692e894c4397312d2d55fe4b70e5692dd27b70.

The Qodo bot incorrectly unescaped Unicode characters in the JSON:
- \u003c (Unicode for <) was changed to <
- \u001b (Unicode for ESC) was changed to event

This broke the JSON structure and validity.

While the core O(N) algorithm is implemented and handles basic transitions, we must stress-test the engine against complex real-world scenarios to ensure the 'Tale of the Project' remains perfectly accurate. Scope includes: (1) High-frequency update bursts (multiple saves within 50ms), (2) Massive batch mutations where 50+ beads are updated in a single sync, (3) Complex state permutations like simultaneous status and dependency changes, and (4) Resiliency testing against transient file-locks or malformed JSONL lines during the diffing window.","notes":"TESTING STRATEGY: We need to develop a dedicated stress-test suite in tests/lib/snapshot-differ-stress.test.ts.

Subject: [PATCH 10/17] fix: address PR bot review comments

Critical fixes:
- Fix duplicated isPolling/pollLastTouched in events route (missing closing brace)
- Add missing path import to realtime.ts (path.basename was used without import)
- Fix error.message leak in sessions and beads/read routes (security)
- Add missing NextResponse import to activity route
- Fix diffDependencies to use composite key (type:target) for accurate tracking

Code quality:
- Fix beadCounts computation in kanban-controls (was counting epic's own deps, not child issues)
- Replace require('path') with ES module imports throughout

Tests: 13/15 passing (2 contract tests remain brittle)

Subject: [PATCH 13/17] fix: address critical security and stability issues

- Fix path traversal vulnerabilities in API route validation functions
- Fix path traversal in readiness-report.mjs artifact validation
- Add file locking to prevent race conditions in agent-reservations.ts
- Fix event ordering in ActivityEventBus by capturing snapshot before modification
- Fix memory leaks in watcher.ts by explicitly removing chokidar listeners
- Add command injection sanitization in mutations.ts

Subject: [PATCH 14/17] fix: replace non-standard flock() with portable
 file-based mutex

The original implementation used fs.flock() which is not available in the
Node.js fs/promises API. Replaced with a portable file-based mutex using
exclusive file creation (flag: 'wx') with retry logic.

This ensures the race condition fix for agent reservations works correctly
across all Node.js versions and platforms.

Subject: [PATCH 15/17] Fix path traversal validation and mutation sanitization

- Fix isValidProjectRoot() in 4 API routes to properly prevent path traversal
  by using path.relative() to ensure paths stay within allowed base directory
  (replaces ineffective normalized.includes('..') check)

- Fix readiness-report.mjs to remove misleading path traversal validation
  that was ineffective after path.resolve() removes '..' segments

- Fix asNonEmptyString() in mutations.ts to only remove control characters
  while preserving backslashes (for Windows paths) and punctuation (for user text)

These changes address security review comments about ineffective path traversal
checks and mutation input corruption.

+# Agent Sessions Hub
+
+## Overview
+The Agent Sessions Hub (`/sessions`) provides a unified command workspace for tracking multi-agent coordination across your BeadBoard projects. It combines task status, agent communication, and derived activity into a social-dense interface optimized for understanding "who's doing what" at a glance.
+
+## Features
+
+### 1. Epic-Grouped Task Feed
+Tasks are automatically organized by their parent Epic, providing logical context for understanding work scope.
+
+- **Session State Indicators**: Each task displays its real-time state (active, reviewing, needs_input, completed, stale)
+- **Owner & Actor Tracking**: See who owns the task and who last acted on it
+- **Communication Badges**: Unread message counts and pending acknowledgment flags
+
+### 2. Agent Communication Integration
+Built-in cross-agent messaging system for coordination without leaving the dashboard.
+
+**Message Types:**
+- `HANDOFF` - Pass context to another agent
+- `BLOCKED` - Request help or flag blockers
+- `INFO` - Share updates or documentation
+
+**Communication Features:**
+- Inbox view with unread/read/acked states
+- Required acknowledgments for critical handoffs
+- Per-bead conversation threads
+
+### 3. Agent Statistics & Productivity Metrics
+Real-time performance tracking for each registered agent.
+
+**Metrics Tracked:**
+- Active tasks (currently in progress)
+- Completed tasks (closed beads)
+- Handoffs sent (coordination events)
+- Recent wins (last 3 completed tasks)
+
+### 4. Derived Activity Engine
+Instead of storing history separately, BeadBoard computes activity on-demand by diffing snapshots of `issues.jsonl`.
+
+**Event Types Generated:**
+- Bead lifecycle: created, closed, reopened
+- Status changes: todo → in_progress → done
+- Assignee changes
+- Priority, title, description updates
+- Label and dependency changes
+
+**Persistence:**
+- File-backed ring buffer survives server restarts
+- O(N) snapshot diffing algorithm
+- No separate event database required
+
+## Architecture
+
+### Backend Components
+- **Agent Registry** (`src/lib/agent-registry.ts`): Maintains agent identity and roles
+- **Agent Mail** (`src/lib/agent-mail.ts`): Cross-agent messaging with inbox/ack protocol
+- **Agent Reservations** (`src/lib/agent-reservations.ts`): File/scope locking to prevent collisions
+- **Agent Sessions** (`src/lib/agent-sessions.ts`): Session state derivation and task feed builder
+- **Snapshot Differ** (`src/lib/snapshot-differ.ts`): O(N) diffing engine for activity events
+- **Activity Persistence** (`src/lib/activity-persistence.ts`): File-backed event buffer
+
+### API Endpoints
+- `GET /api/sessions` - Fetch session task feed
+- `GET /api/sessions/[beadId]/conversation` - Get full conversation thread for a bead
+- `POST /api/sessions/[beadId]/comment` - Add a comment to a bead session
+- `POST /api/sessions/[beadId]/messages/[messageId]/read` - Mark message as read
+- `POST /api/sessions/[beadId]/messages/[messageId]/ack` - Acknowledge message
+- `GET /api/agents/[agentId]/stats` - Fetch agent productivity metrics
+
+### Frontend Components
+- **SessionsPage** (`src/components/sessions/sessions-page.tsx`): Main layout and orchestration
+- **TaskCard** components: Visual representation of session state
+- **AgentStatsPanel**: Metrics dashboard per agent
+
+## Session States
+
+Tasks automatically transition between states based on activity and communication:
+
+| State | Description | Visual Indicator |
+|-------|-------------|------------------|
+| `active` | Status is `in_progress`, recent activity | Green pulse |
+| `reviewing` | Under review or verification | Blue |
+| `deciding` | Status is `todo` or `ready`, waiting for claim | Gray |
+| `needs_input` | Status is `blocked` or has pending required acknowledgments | Yellow/Orange |
+| `completed` | Status is `closed` | Green checkmark |
+| `stale` | No activity in 24+ hours | Faded/Red |
+
+## Integration with `bb agent` CLI
+
+The Sessions Hub visualizes data managed by the `bb agent` command-line interface. See `docs/agent-session-flow.md` for the operator workflow.
+
+**Key Commands:**
+- `bb agent register --name <name> --role <role>` - Register agent identity
+- `bb agent send --from <sender> --to <recipient> --bead <id> --category <type>` - Send message
+- `bb agent inbox --agent <name>` - Check messages
+- `bb agent reserve --agent <name> --scope <glob> --bead <id>` - Reserve files
+- `bb agent status --bead <id>` - Check reservation status
+
+## Data Flow
+
+1. **Source of Truth**: `.beads/issues.jsonl` via `bd` CLI
+2. **Activity Generation**: Watcher detects changes → snapshot differ → event bus
+3. **Agent Coordination**: `bb` CLI writes to `.beads/agents/` directory
+4. **UI Refresh**: SSE stream (`/api/events`) pushes updates to frontend in real-time
+
+## Configuration
+
+No configuration required. The Sessions Hub automatically:
+- Discovers registered agents from `.beads/agents/`
+- Builds communication graph from mailboxes
+- Derives session states from current bead status + activity
+
+## Performance
+
+- **O(N) Diffing**: Snapshot differ scales linearly with number of beads
+- **Ring Buffer**: Activity persistence uses fixed-size memory buffer (configurable)
+- **Real-time Updates**: SSE keeps UI synchronized without polling
+
+## Limitations
+
+- Comment interactions are not yet streamed to the timeline
+- Cross-project agent coordination requires agents to be registered in each project
+- Stale threshold is fixed at 24 hours (not user-configurable)
+
