What's Working

45/45 tests pass (31 unit + 14 integration)
Zero clippy warnings, fully formatted
All pre-commit hooks pass
Crate compiles and integrates with workspace

What's Blocked

Nothing is blocked. The crate is complete for Phase 1 MVP.

2. Technical Context

Crate Location

crates/terraphim_orchestrator/ -- 11 files, 2,273 lines (1,796 src + 477 test)

Key Files

| File | Purpose | |------|---------| | src/lib.rs | AgentOrchestrator with tokio::select! reconciliation loop | | src/config.rs | OrchestratorConfig, AgentDefinition, AgentLayer (TOML parsing) | | src/nightwatch.rs | NightwatchMonitor, DriftMetrics, CorrectionLevel, RateLimitTracker | | src/scheduler.rs | TimeScheduler with cron parsing (5-field auto-prepend) | | src/compound.rs | CompoundReviewWorkflow (git log scan, dry-run mode) | | src/handoff.rs | HandoffContext (JSON serialization for agent task transfer) | | src/error.rs | OrchestratorError (9 variants) | | orchestrator.example.toml | 3-agent fleet config (Safety/Core/Growth) | | tests/orchestrator_tests.rs | 8 integration tests | | tests/nightwatch_tests.rs | 3 integration tests | | tests/scheduler_tests.rs | 3 integration tests |

Architecture

OrchestratorConfig (TOML)
        |
        v
AgentOrchestrator
  |-- TimeScheduler -------> cron triggers (Safety=always, Core=cron, Growth=on-demand)
  |-- NightwatchMonitor ----> drift alerts (Normal/Minor/Moderate/Severe/Critical)
  |-- CompoundReview -------> nightly git log scan
  |
  |-- AgentSpawner (existing) --> OS processes
  |-- RoutingEngine (existing) -> keyword-based LLM routing

Dependencies (new to this crate)

cron = "0.13" -- cron expression parsing
toml = "0.8" -- config file parsing

Key Design Decisions

Kubernetes-style reconciliation loop with tokio::select!
Weighted drift calculation: error_rate 0.4 + command_success_rate 0.3 + health_score 0.3
Zero-sample guard: drift returns 0.0 when no data collected
Cron auto-prepends "0" seconds field for 5-field expressions
CostLevel::Cheap (not Low) for spawned agent providers
Edition 2021 (not workspace 2024) for broader compatibility

3. Fixes Applied During Session

| Issue | Resolution | |-------|-----------| | DriftMetrics::default() caused non-zero drift after reset | Added sample_count == 0 guard in calculate_drift() | | TimeScheduler missing Debug trait | Added #[derive(Debug)] | | CostLevel::Low doesn't exist | Changed to CostLevel::Cheap | | Pre-commit hook flaky test (terraphim_update) | Soft-reset and re-committed with hooks passing | | haystack_jmap excluded but now a dep of middleware | Removed from workspace exclude list | | .docs/ in .gitignore | Removed to track design documents | | Trailing whitespace in .docs files | Fixed with sed before commit |

4. Deferred to Phase 2

| Feature | Why Deferred | |---------|-------------| | Meta-Learning Agent | Beyond Phase 1 MVP scope | | Deep context handoff (full session state) | Shallow JSON handoff sufficient for now | | A/B test framework | Not needed for initial deployment | | UI dashboard for monitoring | Programmatic API is sufficient | | Compound review PR creation | Placeholder in code; dry-run default | | NightwatchMonitor periodic evaluation trigger in run loop | VAL-3 advisory | | Multi-project coordination | Phase 3 scope |

5. Validation Advisory Issues

| ID | Description | Severity | |----|-------------|----------| | VAL-1 | Compound review PR creation is placeholder even when create_prs=true | Advisory | | VAL-2 | Reconciliation loop has 2 select! branches vs 4 in design | Advisory | | VAL-3 | NightwatchMonitor.evaluate() needs periodic trigger in run loop | Advisory | | VAL-4 | Actual size (2273 lines) exceeded estimate (950 lines) | Low |

6. Next Steps for Continuation

Integration test with real CLI tools on BigBox -- spawn actual echo/codex/claude processes
Wire evaluate() into the reconciliation loop (VAL-3) -- add a tokio::time::interval branch to select!
Implement PR creation in compound review (VAL-1) -- call gh pr create when create_prs=true
Create GitHub issue to track remaining Phase 2 work
BigBox tmux deployment -- set up tmux sessions per the dark factory architecture
