❯ AUDIT TIME: Inspect the git repo for HEXAGONAL ARCHITECTURE violations,   
  SOLID violations DRY violations. Inspect the tests for BRITTLE,           
  randomness, timing, or non-determinism. Check                             
      that tests are verifying behavior and not implementation details.     

⏺ I'll run parallel audits across the codebase for each concern area.

⏺ Launched 4 parallel audit agents:

  1. Hexagonal architecture violations — scanning domain layer for illegal
  imports from infrastructure/CLI
  2. SOLID + DRY violations — checking SRP, OCP, LSP, ISP, DIP across services;
  hunting duplicated logic
  3. Brittle tests — searching for timing deps, non-determinism, order coupling,
   implementation-detail testing
  4. Port/adapter contract integrity — verifying all ports are fully implemented
   and no adapter-specific leakage

  I'll compile the findings once all agents report back.

  Codebase Audit Report

  1. Hexagonal Architecture — CLEAN

  No violations found across 136+ domain files, 15 infrastructure files, and 14
  port files. The dependency rules are strictly enforced:

  - Domain never imports infrastructure or CLI
  - Infrastructure never imports CLI
  - All I/O dependencies are injected via ports

  4 documented node:crypto usages in domain are justified and explicitly
  annotated (trust crypto, seek cache keys, default crypto port fallback).

  2. Port/Adapter Contracts — CLEAN

  All 14 ports are fully implemented by their adapters. No stubs, no "not
  implemented" throws, no contract violations. One intentional adapter-specific
  method (isAncestor() on GitGraphAdapter) is guarded by a runtime typeof check
  in SyncProtocol.

  2 deprecated adapter re-exports remain: PerformanceClockAdapter and
  GlobalClockAdapter (both alias ClockAdapter).

  3. SOLID Violations

  SRP — 7 files with mixed concerns

  └────────────────────┴──────┴──────────────────────────────────────────────┘

  OCP — 3 patterns

  - 4 message codecs repeat identical trailer extraction + validation switch
  logic (~200 lines total)
  - JoinReducer.validateOp() — switch on op.type requires modification for new
  op types
  - GitGraphAdapter — no extensibility hook for new Git commands

  LSP — 1 minor

  - BitmapNeighborProvider constructor throws if missing deps, rather than
  failing lazily at method invocation

  ISP — 1 notable

  - GraphPersistencePort is a 23-method composite of 5 focused ports. Services
  needing only blob I/O must accept the full interface. (Mitigated by focused
  ports existing separately.)

  DIP — 1 pattern

  - WarpGraph directly instantiates SyncController, MaterializedViewService,
  TemporalQuery instead of accepting them via injection

  LOW-MEDIUM — Error message string matching

  Multiple tests use exact .toThrow('message text') instead of error type or
  regex patterns. Minor message rewording breaks them.

  Positive: Golden vector hashes

  AuditReceiptService.test.js:104 hardcodes expected SHA-256 digests. While
  technically brittle to algorithm changes, these are correct for a 
  cryptographic system — they catch accidental canonicalization regressions.
  Keep these.

  Priority Recommendations

  1. Test refactoring (highest ROI): Replace private-field access with behavior
  assertions. Move fake timers to beforeEach/afterEach. Add seeds to property
  tests.
  2. Extract message codec template: ~200 lines of identical trailer validation
  across 4 files.
  3. Extract readBoundedStream(): ~90 lines duplicated across 3 HTTP adapters +
  shared MAX_BODY_BYTES.
  4. WarpGraph decomposition: Extract SubscriptionManager, CacheCoordinator,
  ProvenanceManager to reduce the god object.
  5. JoinReducer split: Move validateOp + state factory + diff helpers to
  separate modules.
