Storage & Events (P1):
- DatabaseManager + MigrationRunner (19 tables, 22 indexes, 5 schema_meta seeds)
- 16 repositories (Repository<T,I,U> pattern, INV-1 status columns via EventStore.project only)
- EventSchemaRegistry (54 durable + 7 ephemeral), EventStore, EventBus, EventIngestor
- Project/Session/Artifact/Evidence stores + 8-step Recovery

Tools & Permission (P2):
- PathClassifier (8 categories), CommandRiskAnalyzer (10 categories), SecretRedactor
- PermissionEngine 6-layer evaluation (capability→profile→task_scope→risk→credential→user_prompt)
- ToolRegistry with 20+ tools across fs/shell/git/project/artifact/context/permission/doctor
- CapabilityManifestValidator + CapabilityRegistry

LLM & Context (P3):
- ModelConfigLoader, CapabilityMatrix, AnthropicCanonicalConverter
- AnthropicAdapter + OpenAICompatibleAdapter
- ProviderManager facade
- PromptLayerLoader (L0/L1/L3/L5), CompactionPolicy, ContextAssembler

Worker IPC & Scheduler (P4):
- WorkerProtocol (NDJSON), WorkerProcess (exit codes 0-5), WorkerManager (spawn/handshake)
- WorkerRuntime (INV-3: IPC only, no direct fs/shell/SQLite)
- 5 worker roles (Executor/Reviewer/Debugger/Compactor/ExperienceMiner)
- TaskGraph, WavePlanner, RetryPlanner, AgentMonitor, WorkspaceManager
- Scheduler (state machine), 8-step Recovery

C++ Toolchain (P5):
- DiagnosticParser, CppProjectDetector, CMakeConfigurator, CppBuilder
- CppTestRunner, CppcheckRunner, ClangdClient
- CppToolRegistrar + capability manifest

Projection & TUI (P6):
- ProjectionStore (hydrate/apply/snapshot/subscribe)
- TuiApp + 8 components (Session/Task/Agent/Tool/Diff/Evidence/Permission/Blocker/Hud)
- ProjectionClient in-process ref

Agents & Knowledge (P7):
- MainAgent, ArchitectureDesigner
- DebugKnowledgeStore + LearnedMemoryStore (single-writer, outbox model)
- Role integration wiring

CLI & Doctor & Release (P8):
- Logger + DeveloperLogEncryptor (AES-256-GCM)
- DoctorService (self_bootstrap first)
- RuntimeApp + ServiceRegistry
- 11 CLI commands: run/init/doctor/provider/resume/compact/history/session/restore/e2e/release
- CliEntrypoint + air<TODO>

Audit (in AirPlan/docs/):
- Deepseek开发阶段审计.md (97 findings)
- Opus开发阶段审计.md (140+ findings, 18 P0 blockers)
- MiniMaxM3开发阶段审计.md (18 P0 blockers, focuses on executability)
- AirPlan/TODO.md (technical debt + 42 TODOs by phase)
