# State: Flynn Operator DX

## Project Reference

**Core Value:** Make Flynn easier to reason about, configure, and monitor
**Milestone:** Operator DX
**Phases:** 3

## Current Position

**Phase:** 2 — Config Overlays
**Plan:** 1 of 2 complete (02-01 done)
**Status:** in_progress
**Progress:** █████░░░░░ 1/3 phases complete (02-01 of Phase 2 done)

## Phase Status

| Phase | Status | Plans |
|-------|--------|-------|
| 1 — Daemon Decomposition | **complete** | 3/3 plans complete |
| 2 — Config Overlays | **in_progress** | 1/2 plans complete |
| 3 — Live Ops Dashboard | not_started | — |

## Performance Metrics

| Metric | Value |
|--------|-------|
| Test count | 1077 (baseline, verified across all plans) |
| daemon/index.ts lines | 140 (from 1087 baseline, -87%) |
| Total daemon modules | 9 files, 1271 lines |
| Plan 01-01 duration | 9 min |
| Plan 01-01 tasks | 3/3 |
| Plan 01-02 duration | ~25 min |
| Plan 01-02 tasks | 3/3 |
| Plan 01-03 duration | ~8 min |
| Plan 01-03 tasks | 2/2 |
| Plan 02-01 duration | 3 min |
| Plan 02-01 tasks | 2/2 |

## Accumulated Context

### Key Decisions
- Decompose god file incrementally, not rewrite
- Config overlays over separate files
- Extend existing vanilla JS dashboard
- Skip structured logging — dashboard will reveal what metrics matter
- Factory function pattern (initX(deps) → result) for daemon subsystem extraction
- initTools() kept synchronous — only shutdown callbacks are async
- Backward-compatible re-exports from daemon/index.ts for model functions
- Deps-interface factory pattern (ChannelsDeps, AgentsDeps) for explicit dependency injection
- registerChannels returns cronScheduler so Tier 1 cron tools can still be wired in startDaemon
- Lifecycle wiring stays in the module that owns the resource (agents.ts owns sandbox shutdown)
- Grouped skills/MCP/pairing/gateway/startup into services.ts rather than multiple tiny modules
- getChannelAgents callback for late-binding channel agents into gateway token usage reporting
- Type-only imports in index.ts for values only referenced in DaemonContext type definition
- Overlay merge before env expansion and Zod validation — overlays don't need required fields
- Arrays in overlays replace (not concat) — explicit override semantics
- resolveOverlayPath returns path without checking existence — callers decide error handling

### Technical Notes
- daemon/index.ts now 140 lines — thin composition root: imports → init calls → wire → return DaemonContext
- 8 extracted modules: models.ts (251), memory.ts (99), tools.ts (89), routing.ts (239), agents.ts (48), channels.ts (102), services.ts (269), lifecycle.ts (34)
- Factory pattern established for all modules: initX(deps) → result
- Tier 1 agent tools (session, agent list, message send, cron) remain in index.ts — they need deps from multiple init functions
- Web dashboard is vanilla JS SPA at src/gateway/ui/
- Config loader at src/config/loader.ts, schema at src/config/schema.ts (409 lines)
- deepMerge + overlay-aware loadConfig in loader.ts; resolveOverlayPath + overlay-aware loadConfigSafe in cli/shared.ts
- FLYNN_ENV maps to {configDir}/{env}.yaml sibling file; no env = no overlay (backward compatible)

### TODOs
_(none)_

### Blockers
_(none)_

## Session Continuity

**Last session:** Plan 02-01 (core overlay merge) completed
**Stopped at:** Completed 02-01-PLAN.md
**Next action:** Execute Plan 02-02 (doctor overlay validation check)
