Phase 2 Context

• Date: 2026-03-09 to 2026-03-11 (8h, parallel with Dev A + B)
• Team: Dev A (error handling, 6h), Dev B (performance, 5h), Dev C (documentation, 8h)
• Standup: 09:00, 12:00, 18:00 UTC daily
• Merge Gate: 12:00 UTC on 2026-03-11 (documentation finalized)
• Critical Path: Dev C (8h) determines final Phase 2 delivery date

🎯 Your Mission

Finalize EPIC-10 documentation and knowledge transfer materials:

1. Publish bootstrap_agent Tool Guide (API spec + examples + SLA)
2. Write Implementation Summaries for Dev A & B (TASK-10-06 + TASK-10-07 recap)
3. Author EPIC-10 Architecture Decision Record (5 key design decisions + rationale)
4. Create Operations Runbook (SLA monitoring, incident response, disaster recovery)

Outcome: Self-contained, production-ready documentation package for operators + future maintainers.

Deliverable 2: Implementation Summary — TASK-10-06 (AC-3)

File: Docs/mcp-context-server/delivery/mcp-maintenance/milestones/milestone_02/epic_10/implementation-summary/TASK-10-06-ErrorHandling-2026-03-10.md

• AC-3: Error Handling Summary

    • Why HTTP 400 for client errors (standard, clear)
    • Why prepared statements (SQL injection prevention)
  • Performance impact: Validation < 5ms per call (negligible)
  • Dependencies: None (standalone validation layer)

Deliverable 3: Implementation Summary — TASK-10-07 (AC-4)

File: Docs/mcp-context-server/delivery/mcp-maintenance/milestones/milestone_02/epic_10/implementation-summary/TASK-10-07-Performance-2026-03-11.md

    • Concurrency: 50 agents, 1000 queries, 100% success
  • Performance decisions:
    • Why Promise.all() (true parallelism for load sim)
    • Why 10% degradation threshold (balance perf + noise)
    • Why SQLite WAL mode (read performance under load)
  • CI/CD integration: Regression gate fails if p95 > baseline × 1.1

Deliverable 4: EPIC-10 Architecture Decision Record (AC-5)

File: database/standards/adrs/EPIC-10-ADR.md

• AC-5: 5 ADR Decisions Documented

  Decision 1: Session IDs = UUID v4 (crypto-strong)

  • Context: Agents need unique, collision-free session identifiers
  • Decision: Use crypto-strength UUID v4 (not sequential)
  • Rationale: No central coordination needed, scales to billions
  • Trade-off: Not temporally ordered (can sort by timestamp instead)
  • Evidence: 10,000 generation tests, 0 collisions

  Decision 2: Error Response = Standardized Format

  • Context: Different error sources (validation, DB, timeout) need unified handling
  • Decision: All errors follow { success: false, error_code, error_message, details }
  • Rationale: Clients parse consistently, reduces error handling complexity
  • Trade-off: Minimal overhead on response size
  • Implementation: ErrorResponses builder class

  Decision 3: Input Validation = Strict Regex

  • Context: Prevent injection attacks at input boundary
  • Decision: Use regex /^[a-z-]+$/ for domain, /^[a-z_]+$/ for role
  • Rationale: Simple, fast, safe for known patterns; avoids parser complexity
  • Trade-off: Limited naming flexibility (no caps, special chars)
  • Evidence: OWASP test matrix, 0 injection bypasses

  Decision 4: Performance Baseline = 50ms p95

  • Context: bootstrap_agent must be fast (entry point for all agents)
  • Decision: SLA target p95 < 50ms @ 50 concurrent
  • Rationale: User perceives instant (<50ms), scales to 50 agents
  • Trade-off: Must optimize queries, indexing, connection pooling
  • Evidence: Baseline established, actual p95 ≈ 35ms (exceeds target)

  Decision 5: Graceful Degradation = Cache Fallback

  • Context: If optional data (runbook, schema) unavailable, still serve session
  • Decision: Return valid but reduced payload instead of error
  • Rationale: Higher availability (serve something > serve nothing)
  • Trade-off: Agents must handle optional fields
  • Future: Implement fallback cache for offline resilience

Structure:

# ADR-005: EPIC-10 bootstrap_agent Design Decisions

## 1. Context
(Problem we were solving)

## 2. Decisions

- Trade-offs: Requires optimization
- Evidence: Actual p95 ≈ 35ms (exceeds target)

### Decision 5: Graceful Degradation Fallback
- Rationale: Availability > Freshness
- Trade-offs: Agents must handle optional fields
