# 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:** v0.2 complete (commit pending) → next v0.3 OPC UA

## Current Position

Milestone: v0.2 Machine Management UX
Phase: 2 of 2 (Machine Management UX) — COMPLETE
Plan: 02-A ✓ 02-B ✓ 02-C ✓

## 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.
