3. UAT Scenarios and Results

3.1 Scenario: Create orchestrator from example config

Steps: Load orchestrator.example.toml, create AgentOrchestrator, verify state. Evidence: test_example_config_creates_orchestrator (integration test) Result: PASS -- 3 agents parsed (Safety, Core, Growth), orchestrator created successfully.

3.2 Scenario: Safety agents spawn immediately on startup

Steps: Call run() with Safety-layer agent; verify it is selected for immediate spawn. Evidence: test_scheduler_layer_partitioning confirms Safety agents in immediate_agents(); test_orchestrator_creates_and_initial_state confirms no premature spawning. Result: PASS -- Safety agents correctly identified for immediate spawn.

3.3 Scenario: Core agents scheduled via cron

Steps: Define Core agent with cron schedule; verify scheduler parses and stores it. Evidence: test_schedule_parse_cron validates "0 3 * * *" parses; test_scheduler_fires_at_cron_time validates event injection and retrieval via channel. Result: PASS -- cron expressions parsed and events flow through scheduler.

3.4 Scenario: Invalid cron schedule rejected

Steps: Provide invalid cron expression; verify error. Evidence: test_schedule_invalid_cron -- "not a cron" returns SchedulerError. Result: PASS -- clear error message with original expression.

3.5 Scenario: Nightwatch detects escalating drift levels

Steps: Feed increasing error rates; verify drift classification at each level. Evidence: test_drift_metrics_normal (0% -> Normal), test_drift_metrics_minor (15% -> Minor), test_drift_metrics_moderate (30% -> Moderate), test_drift_metrics_severe (60% + degraded health -> Severe), test_drift_metrics_critical (90% + unhealthy -> Critical). Result: PASS -- all 5 levels correctly classified with expected thresholds.

3.6 Scenario: Nightwatch evaluate() emits alerts

Steps: Accumulate high error rate, call evaluate(), check channel. Evidence: test_evaluate_emits_alerts -- 90% error agent triggers alert via channel with level >= Moderate. Result: PASS -- alerts flow through mpsc channel.

3.7 Scenario: Drift reset after agent restart

Steps: Accumulate errors, reset, verify clean slate. Evidence: test_drift_reset and test_nightwatch_reset_isolated_to_agent (integration test confirming reset affects only target agent). Result: PASS -- reset zeroes out metrics without affecting other agents.

3.8 Scenario: Multiple agents tracked independently

Steps: Create two agents with different error profiles; verify independent scores. Evidence: test_nightwatch_multi_agent_independent_tracking -- agent-a (80% errors) has higher drift than agent-b (5% errors). Result: PASS -- per-agent isolation confirmed.

3.9 Scenario: Context handoff between agents

Steps: Serialize HandoffContext to JSON/file; deserialize; verify round-trip. Evidence: test_handoff_roundtrip_json, test_handoff_roundtrip_file, test_handoff_context_file_roundtrip (integration). Result: PASS -- all fields preserved including timestamps, decisions, files.

3.10 Scenario: Compound review dry run

Steps: Run compound review with create_prs=false. Evidence: test_compound_review_dry_run -- scans real git repo, returns findings, no PR created. Result: PASS -- dry run produces findings list without side effects.

3.11 Scenario: Compound review handles nonexistent repo

Steps: Point compound review at /nonexistent/path. Evidence: test_compound_review_nonexistent_repo -- returns CompoundReviewFailed error. Result: PASS -- graceful error handling.

3.12 Scenario: Orchestrator graceful shutdown

Steps: Request shutdown, verify run() exits cleanly. Evidence: test_orchestrator_shutdown_cleans_up -- shutdown() then run() returns within 5s timeout. Result: PASS -- clean shutdown path works.

3.13 Scenario: Rate limit tracking

Steps: Record calls, set limits, verify exhaustion detection. Evidence: test_rate_limit_tracker_basic (99 remaining after 1 call with limit 100), test_rate_limit_tracker_exhausted (0 remaining, can_call returns false). Result: PASS -- rate limiting functional.

3.14 Scenario: Error messages are descriptive

Steps: Construct each error variant; verify display includes all context. Evidence: test_error_variants_display -- SpawnFailed, AgentNotFound, HandoffFailed all include relevant agent names and reasons. Result: PASS -- actionable error messages.

6. Gap Assessment: Delivered vs Deferred

Fully Delivered

1. AgentOrchestrator reconciliation loop -- tokio::select! over scheduler + nightwatch
2. TimeScheduler with cron expressions -- standard 5-field cron, auto-prepends seconds
3. NightwatchMonitor with drift detection -- weighted algorithm, 5 severity levels, channel-based alerts
4. OrchestratorConfig with TOML parsing -- full schema with defaults
5. HandoffContext for shallow transfers -- JSON serialization + file I/O
6. CompoundReviewWorkflow -- git log scanning, dry-run mode
7. RateLimitTracker -- per-agent per-provider sliding window
8. AgentStatus reporting -- programmatic query for all active agents
9. Error handling -- 9 error variants covering all failure modes
10. Example configuration -- 3-agent fleet (one per layer)

Partially Delivered (Phase 1 scope complete, Phase 2 enhancement needed)

1. SC-5 (KG-based context sharing): Shallow handoff is delivered; deep KG integration needs terraphim_automata integration in Phase 2.
2. SC-6 (PR creation): Git log scan and finding extraction work; actual PR creation via gh CLI is placeholder. This is correct per design -- create_prs=false is the Phase 1 default.
3. SC-7 (Observer dashboard): Programmatic agent_statuses() API exists; no CLI or WebSocket dashboard. Deferred to Phase 2 per design.

Correctly Deferred to Phase 2

| Item | Rationale | |------|-----------| | Meta-Learning Agent | Research doc marks as Phase 2 | | Deep context handoff (full session state) | Research doc marks as Phase 2; requires CLI-specific format parsing | | A/B test framework | Research doc marks as Phase 2 | | Observer dashboard (Svelte/CLI) | Research doc marks as Phase 2; WebSocket exists in server | | Multi-project coordination | Research doc marks as Phase 3 |

Not Delivered (not requested)

| Item | Why Not Required | |------|-----------------| | Rewriting spawner/router/supervisor | Explicitly out of scope -- these are production-ready | | Multi-machine distributed agents | BigBox single-server target | | Custom IPC protocol | Design explicitly rejected | | Database for agent state | Design explicitly rejected |

7. Risk Assessment Post-Implementation

| Risk (from Research) | Mitigation Status | Remaining Risk | |---------------------|-------------------|----------------| | CLI tools not available | spawn_agent() returns SpawnFailed with clear message | Low -- operator verifies during deployment | | Agent process leaks | Delegates to AgentSpawner SIGTERM->SIGKILL; shutdown_all_agents() iterates | Low | | Drift detection false positives | Conservative thresholds (10/20/40/70%); Minor level just logs | Medium -- needs production tuning | | Context handoff data loss | JSON roundtrip verified by 3 tests; file-based persistence | Low | | Compound review bad PRs | create_prs=false by default; dry-run first | Low | | Resource exhaustion | Resource limits delegated to AgentSpawner rlimit | Low | | API rate limits | RateLimitTracker implemented; can_call() gate | Low |

8. Defects and Issues

From Phase 4 (all resolved)

| ID | Description | Resolution | Verified | |----|-------------|------------|----------| | DEF-1 | CompoundReviewWorkflow::run takes no spawner/router args | Simplified to standalone git scan per Phase 1 scope | YES -- compound.rs:40 | | DEF-2 | RateLimitTracker::update_limit takes 2 args not 3 | Fixed to 3-arg signature | YES -- nightwatch.rs:343 | | DEF-3 | Some OrchestratorError variants not exercised | Integration test added | YES -- orchestrator_tests.rs:213-234 | | DEF-4 | Moderate correction maps to RestartAgent | Documented as intentional | YES -- nightwatch.rs:282 |

New Issues Found During Phase 5

| ID | Severity | Description | Phase of Origin | Recommendation | |----|----------|-------------|----------------|----------------| | VAL-1 | Advisory | Compound review PR creation is placeholder (always returns false/None even when create_prs=true) | Phase 3 (Implementation) | Phase 2 should wire to agent spawn for actual PR creation | | VAL-2 | Advisory | Reconciliation loop has only 2 branches in select! (scheduler, nightwatch); design showed 4 branches (scheduler, nightwatch, message_rx, compound_trigger) | Phase 3 | CompoundReview events flow through scheduler channel; message_rx deferred. This is acceptable simplification for Phase 1. | | VAL-3 | Advisory | NightwatchMonitor.evaluate() must be called externally (no background timer task) | Phase 3 | Orchestrator should add a periodic tokio::time::interval arm in the select! loop to call evaluate(). Currently the caller must trigger evaluation. | | VAL-4 | Low | Size exceeded estimate (2273 vs 950 lines) | Phase 2 (Design) | Not a defect -- additional tests and RateLimitTracker (which was added during design refinement) account for the growth. |

9. Production Readiness Assessment

Readiness Checklist

| Criterion | Status | Notes | |-----------|--------|-------| | All tests pass | YES | 45/45 (31 unit + 14 integration) | | Zero clippy warnings | YES | Clean | | Formatting compliant | YES | cargo fmt --check passes | | Example config provided | YES | orchestrator.example.toml | | Error handling covers failure modes | YES | 9 error variants | | No panics in production paths | YES | All panics are in test code only; expect() on channels is guarded by ownership invariant | | Graceful shutdown | YES | shutdown() + shutdown_all_agents() | | Workspace integrated | YES | Auto-included via crates/* glob | | Rollback plan | YES | Remove from workspace exclude list; no other crates modified | | Documentation | PARTIAL | Struct/method doc comments present; no README.md (not requested) |

Production Deployment Prerequisites (outside crate scope)

1. Verify claude/opencode/codex CLIs are installed on BigBox
2. Copy orchestrator.example.toml to orchestrator.toml and adjust paths
3. Set create_prs = false for initial 2-week burn-in period
4. Add periodic evaluate() trigger in orchestrator run loop (VAL-3)

10. Sign-Off Recommendation

PASS -- The terraphim_orchestrator crate meets the Phase 1 MVP requirements as defined in the research document and design document. All 7 success criteria are either fully delivered (SC-1, SC-2, SC-3, SC-4) or delivered to the Phase 1 scope boundary (SC-5, SC-6, SC-7). All 7 gap analysis items are addressed. All non-functional requirements are met. All Phase 4 defects are resolved.

Advisory conditions for Phase 2 planning:

• VAL-1: Wire CompoundReviewWorkflow to actual agent-based PR creation
• VAL-3: Add periodic NightwatchMonitor.evaluate() call in the reconciliation loop
• SC-5: Integrate terraphim_automata for KG-based context sharing
• SC-7: Build Observer CLI or dashboard

The crate is ready for integration testing with real CLI tools on BigBox.
