# Project State

## Project Reference

See: .paul/PROJECT.md (updated 2026-07-21)

**Core value:** Operators see live state of every configured machine across heterogeneous protocols in one place, adding machines/protocols without code.
**Current focus:** v0.3 Phase 3 (item selection) shipped → PAUSED. Next: Phase 3.1 theming/UX.

## Current Position

Milestone: v0.3 Data-Item Selection + UX
Phase: 3 (item selection) ✓ SHIPPED — Phase 3.1 (theming/UX) NOT started
Plan: v0.3-backend ✓, v0.3-appui ✓
Status: PAUSED (user requested). Build 0/0, 138 tests + 2 docker-skip.
Last activity: 2026-07-22 — v0.3 item selection: Machine.MonitoredItemIds (opt-in), IProtocolDriver.ProbeAsync, MTConnect probe+filter, Persistence col+migration, monitor.ProbeAsync, config probe→checklist UI (47 items live), detail empty-state.

Progress:
- v0.3: Phase 3 done, Phase 3.1 (theming) pending

## Loop Position

```
PLAN ──▶ APPLY ──▶ UNIFY
  ✓        ✓        ✓     [Phase 3 complete → PAUSED; next PLAN Phase 3.1 theming]
```

## NEXT (on resume)

Phase 3.1 theming/UX (task #34): Fluent light/dark + accent, per-protocol icons (mtconnect/opc/fanuc), curated layout across dashboard/detail/config. App-only. Then v0.4 OPC UA plugin.

## Standing Authorization

Auto-commit + push GREEN chunks (build 0-err + tests pass) to origin/main WITHOUT asking (user-granted 2026-07-22). Never commit red; no force-push; artifact leak-check each time.

## Accumulated Context

### Decisions

| Decision | Phase | Impact |
|----------|-------|--------|
| net48 mandatory (Win7/8 fleet) | 1 | Constrains all deps; Avalonia 11.3.x, Dapper not EF Core |
| App multi-target net48;net8.0 (no DevHead) | 1 | Dev on Linux net8.0, ship net48 |
| Dynamic plugins Assembly.LoadFrom | 1 | Add protocols without touching core |
| Monitor dynamic API (AddOrUpdate/Remove) | 2 | Config changes take effect live, no restart |

### Deferred Issues

| Issue | Origin | Effort | Revisit |
|-------|--------|--------|---------|
| HttpClient created per driver in MTConnect factory | 1 | S | If drivers recreated frequently (socket exhaustion) |
| Robust disconnection UX (state flip nuances) | 2 | S | After config CRUD lands |

### Blockers/Concerns

None.

## Boundaries (Active)

- M2-C touches: src/Junction.App/* (config VM/View, nav, dashboard/detail buttons, Bootstrapper) + src/Junction.Core (AvailableProtocols only) + tests.
- Do NOT touch Domain/Persistence/Protocols in M2-C.

## Session Continuity

Last session: 2026-07-21
Stopped at: M2 complete — 3 screens (dashboard/detail/config), offline detection, dynamic monitor reload. Build 0/0, 125 tests + 2 docker-skip. NOT yet committed.
Next action: commit + push v0.2 (code + .paul/) when user authorizes → then plan v0.3 OPC UA (/paul:plan). Note: OPC UA research Likely (SDK on net48).
Resume context: Manager mode (dotnet-manager), all code delegated to subagents. Full detail in ~/.claude memory/junction-project.md. v0.1 committed 507753f on origin/main; v0.2 uncommitted.
