+# Milestone v1.1: Test Infrastructure
+
+**Status:** SHIPPED 2026-01-31
+**Phases:** 7-9 (including 8.1 inserted)
+**Total Plans:** 8
+
+## Overview
+
+E2E test coverage with mocked agents proving all dispatch/coordination scenarios work end-to-end. MockAgentManager enables testing without real Claude CLI, TestHarness provides full system wiring with database fixtures.
+
+## Phases
+
+### Phase 7: Mock Agent & Test Harness
+
+**Goal**: Mock agent adapter with configurable scenarios + test harness foundation with DB-seeded fixtures
+**Depends on**: v1.0 complete
+**Plans**: 2 plans
+
+Plans:
+- [x] 07-01: MockAgentManager Adapter
+- [x] 07-02: Test Harness with Database Fixtures
+
+**Key deliverables:**
+- MockAgentManager implementing full AgentManager port
+- MockAgentScenario for configurable outcomes (success, crash, waiting)
+- TestHarness with full system wiring (Dispatch, Coordination, Mock agents)
+- Fixture helpers (SIMPLE_FIXTURE, PARALLEL_FIXTURE, COMPLEX_FIXTURE)
+- MockWorktreeManager with configurable merge results
+
+### Phase 8: E2E Scenario Tests
+
+**Goal**: Happy path tests (basic flow, dependencies, merging) + edge case tests (conflicts, interrupts, token limits)
+**Depends on**: Phase 7
+**Plans**: 2 plans
+
+Plans:
+- [x] 08-01: Happy Path E2E Tests
+- [x] 08-02: Edge Case E2E Tests
+
+**Key deliverables:**
+- 6 happy path tests (single task, parallel dispatch, merge flow, complex dependencies)
+- 14 edge case tests (agent crash, merge conflicts, blocked tasks, waiting agents)
+- Test patterns for E2E scenarios with fake timers
+
+### Phase 8.1: Agent Output Schema (INSERTED)
+
+**Goal**: Define structured agent output schema (done/question/error discriminated union) and update ClaudeAgentManager to use `--json-schema` flag for validated output parsing
+**Depends on**: Phase 8
+**Plans**: 2 plans
+
+Plans:
+- [x] 08.1-01: Agent Output Schema & ClaudeAgentManager
+- [x] 08.1-02: MockAgentManager Schema Alignment
+
+**Key deliverables:**
+- Zod schema with discriminated union (done/question/unrecoverable_error)
+- JSON schema export for Claude CLI --json-schema flag
+- ClaudeAgentManager parsing structured output
+- MockAgentManager aligned with schema
+- TestHarness convenience methods (setAgentDone, setAgentQuestion, setAgentError)
+
+### Phase 9: Extended Scenarios
+
+**Goal**: Extended E2E scenario coverage — conflict hand-back round-trip, multi-agent parallel work, recovery/resume flows
+**Depends on**: Phase 8.1
+**Plans**: 2 plans
+
+Plans:
+- [x] 09-01: Conflict & Parallel E2E Tests
+- [x] 09-02: Recovery & Resume E2E Tests
+
+**Key deliverables:**
+- 6 conflict and parallel tests (conflict cycle, resolution, parallel merges)
+- 8 recovery and Q&A tests (state persistence, crash recovery, multi-question flows)
+- Proof that database is source of truth for all state
+
+---
+
+## Milestone Summary
+
+**Decimal Phases:**
+- Phase 8.1: Agent Output Schema (inserted after Phase 8 for structured agent output)
+
+**Key Decisions:**
+- MockAgentManager uses in-memory Map (no database needed)
+- TestHarness pre-seeds idle agents before dispatch
+- Discriminated union on status field for agent output
+- JSON schema passed to Claude CLI via --json-schema flag
+- Database is source of truth for recovery scenarios
+
+**Issues Resolved:**
+- Agent output parsing was hacky string matching — now structured schema
+- No way to test dispatch/coordination without real Claude CLI — MockAgentManager solves this
+
+**Issues Deferred:**
+- None
+
+**Technical Debt Incurred:**
+- None
