[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

  • 17/17 Tests passing

  • Block 2: State Projection (src/state_projection.js)

  • 27 Event Reducers for all event types
  • project(events[]) → State (pure functions)
  • rebuild() from Event Store (deterministic)
  • incrementalUpdate() for live updates

  • 19/19 Tests passing

  • Block 3: Risk Engine (src/risk_engine.js)

  • 6 Gates: Sizing, Hyperliquid Rules, Whitelist, Watchdog, Reconcile, Unmanaged
  • Safety → BLOCK / Observability → WARN (never blocks)
  • checkAll() returns events + decisions
  • 39/39 Tests passing

Architecture Decisions

  • ADR-003: State Model (Event Sourcing)
  • ADR-004: Risk Controls (6 Gates)
  • Sequence-based ordering (not just timestamp)
  • Pure functions: no side effects in state projection

Commits

  • 1e46885 Block 1 Complete: Event Store
  • b64ff9a Block 2 COMPLETE: State Projection (100% green)
  • ??????? Block 3 COMPLETE: Risk Engine (100% green)

Security

  • Safety:Gates may BLOCK trading
  • Observability:Gates may NEVER block trading
  • Hyperliquid-only (paper/mock)
  • All modules: test-first, deterministic
