[v5.0.0-phase4-complete] - 2026-03-27

✅ Phase 4 COMPLETE — System Boundaries (10/10 Tests)

Phase 4 Summary: | Block | Deliverable | Tests | |-------|-------------|-------| | Block 4.1 | Safety Boundary docs | — | | Block 4.2 | Observability Boundary docs | — | | Block 4.3 | Incident Response runbooks | — | | Block 4.4 | Circuit Breaker MVP | 10/10 ✅ | | Block 4.5 | Integration Tests | 10/10 ✅ | | Total | | 10/10 ✅ |

Circuit Breaker States: - CLOSED → Normal operation, trading allowed - OPEN → SAFETY failure, trading BLOCKED - HALF_OPEN → Recovery validation

Key Guarantees: - SAFETY failures → Circuit Breaker OPEN (trading halts) - OBSERVABILITY failures → Log only (NEVER blocks) - Manual reset required: attemptReset() → confirmReset() - All mutations via explicit events

Integration Tests: - IT1-10: Full end-to-end SAFETY/OBSERVABILITY boundary - Event chain verified - Documentation matches runtime behavior

[v5.0.0-phase3-complete] - 2026-03-27

✅ Phase 3 COMPLETE — Observability (68/68 Tests)

Phase 3 Summary: | Block | Deliverable | Tests | |-------|-------------|-------| | Block 3.1 | Logger (structured JSON) | 14/14 ✅ | | Block 3.2 | Health Service + Boundary | 30/30 ✅ | | Block 3.4 | Rebuild CLI | 10/10 ✅ | | Block 3.3 | Report Service | 14/14 ✅ | | Total | | 68/68 ✅ |

Block 3.1: Logger - 5 log levels: DEBUG, INFO, WARN, ERROR, FATAL - Structured JSON output with correlation IDs - Size-based rotation with retention - Console fallback on file errors - Never throws (fail-safe)

Block 3.2: Health Service - Continuous health monitoring (30s interval) - SAFETY/OBSERVABILITY strict boundary - SAFETY failure → BLOCK/PAUSE + Event + Log - OBSERVABILITY failure → WARN + Log (never blocks) - Discord webhook integration - isPaused tracking with resumeTrading()

Block 3.4: Rebuild CLI - rebuild_state.js CLI tool - --dry-run mode (show diff) - --force mode (apply with backup) - State validation: Rebuild == Live - Automatic backup before force

Block 3.3: Report Service - Hourly reports: Positions, PnL, Trades, Health - Daily session recaps - Queue on Discord failure - Retry with exponential backoff (5s, 15s, 30s, 60s) - Dedup against spam (5 min cooldown) - Health pause visibility

[v5.0.0-phase2-complete] - 2026-03-08

✅ Phase 2 COMPLETE — Core Reliability (103/103 Tests)

Block 4: Reconcile Engine - src/reconcile.js — 4 Mismatch Detectors - Ghost Position: Internal exists, External missing → BLOCK - Unmanaged Position: External exists, Internal missing → BLOCK/WARN - Size Mismatch: Tolerance-based (10 bps = 0.1%) - Side Mismatch: Direction conflict → BLOCK - Pure functions, deterministic - Tests: 28/28 passing

Phase 2 Stats: | Block | Module | Tests | |-------|--------|-------| | Block 1 | Event Store | 17/17 ✅ | | Block 2 | State Projection | 19/19 ✅ | | Block 3 | Risk Engine | 39/39 ✅ | | Block 4 | Reconcile | 28/28 ✅ | | Total | | 103/103 ✅ |

Architecture Decisions - Sequence-based ordering (deterministic) - Safety gates BLOCK, Observability gates WARN - Tolerance-based severity (Size mismatch) - Pure functions throughout

Safety - All gates tested, no live trading paths - Hyperliquid paper/mock only - Deterministic: same input → same output

Tag: v5-phase2-block4-complete

Added

  • Block 1: Event Store (src/event_store.js)
  • SQLite Events table with sequence for deterministic ordering
  • Idempotent append via ON CONFLICT(event_id) DO NOTHING
  • Query interface with pagination
