# AI-DLC State Tracking

## Project Information
- **Feature Name**: Local Dev Master/Slave Setup
- **Feature Slug**: local-dev-master-slave-setup
- **Project Type**: Brownfield
- **Start Date**: 2026-07-02T00:00:00Z
- **Current Stage**: ✅ CLOSED — feature complete, including post-completion live-testing follow-up fixes (2026-07-04); no further work planned
- **Branch**: unknown

## Workspace State
- **Existing Code**: Yes
- **Reverse Engineering Needed**: No (artifacts exist in `aidlc-docs/_shared/reverse-engineering/`)
- **Workspace Root**: K:\Development\Projects\SlpModularCms

## Code Location Rules
- **Application Code**: Workspace root (NEVER in aidlc-docs/)
- **Feature Documentation**: aidlc-docs/features/local-dev-master-slave-setup/ only
- **Shared Artifacts**: aidlc-docs/_shared/

## Language Configuration
- **Documentation Language**: English
- **Conversation Language**: Dutch (User Language)

## Extension Configuration
[Will be populated during Requirements Analysis]

## Execution Plan Summary
- **Total Stages**: Workspace Detection, Requirements Analysis, User Stories (skipped), Workflow Planning, Application Design, Units Generation, Code Generation (x2 units), Build and Test
- **Stages to Execute**: Workflow Planning, Application Design, Units Generation, Code Generation (Unit 1: Backend dual-instance hosting; Unit 2: Frontend dual-instance tooling & runbook), Build and Test
- **Stages to Skip**: User Stories (dev tooling, no user-facing change); Functional Design, NFR Requirements, NFR Design, Infrastructure Design (all per-unit — no new business logic, NFRs already fully captured in requirements.md, no infrastructure/cloud involved)

## Stage Progress

### 🔵 INCEPTION PHASE
- [x] Workspace Detection — Complete
- [x] Requirements Analysis — Complete (`inception/requirements/requirements.md`)
- [x] User Stories — Skipped (dev tooling, no user-facing functional change)
- [x] Workflow Planning — Complete (`inception/plans/execution-plan.md`)
- [x] Application Design — Complete (`inception/application-design/`)
- [x] Units Generation — Complete (`inception/application-design/unit-of-work*.md`)

### 🟢 CONSTRUCTION PHASE
- [x] Unit 1 (Backend dual-instance hosting) — Code Generation complete (`construction/unit-1-backend-dual-instance-hosting/code/summary.md`); build + full test suite verified green; manual module-discovery check confirms slave excludes Master
- [x] Unit 2 (Frontend dual-instance tooling & runbook) — Code Generation complete (`construction/unit-2-frontend-dual-instance-tooling/code/summary.md`); includes `pnpm dev:all` compound launcher, per-instance tab titles, and module-capability gating (`ModuleGuard`/`useSystemCapabilities`) so the Master-only `/cms` page is hidden on a slave
- [x] Build and Test — Complete (`construction/build-and-test/build-and-test-summary.md`); the earlier "no local SQL Server" assumption was disproven (this environment does have a reachable local instance) — full live master+slave connectivity, migrations, and status push/pull were all verified end-to-end, not just via automated tests

### 🟣 POST-COMPLETION FIXES (2026-07-04, same feature, live-testing follow-ups)
Running master and slave side by side surfaced several real gaps in the underlying master/slave protocol (owned by `master-cms-module`, exercised here for the first time by an actual second instance) and one local-dev-only cookie quirk. All fixed and verified; full detail in `audit.md`:
- Slave connection string / real `appsettings.local.json` for the slave
- Missing Core/Identity migration on the slave DB
- `/cms` page wrongly visible on a slave (→ module-capability gating, see Unit 2 above)
- CMS instance status badge styling now matches the dashboard badge
- Master-gate status not reflected on the slave's own dashboard (`PersistentAvailabilityService` now merges the master gate)
- Slave stuck on stale status after a restart (`IntegrityCheckBackgroundService` startup tick + status re-push)
- Slave stuck on stale status after being set `Inactive` (now releases the gate)
- Added the originally-specified slave-pull + fail-open (`MasterStatusPollingBackgroundService`, `GET /api/v1/SlaveStatus`)
- Local availability changes on a master-controlled slave now rejected (409) and the Settings UI locked, instead of a misleading "success"
- Refresh-token cookie collision between master/slave on `localhost` — explained as expected local-dev behavior (not fixed; production uses separate real domains)
- `pnpm dev:all` compound dev-server launcher added
- `master-cms-module`'s own design docs corrected to match this as-built behavior (see that feature's `audit.md`)

All committed together in `0447993` — "Completes local-dev-master-slave-setup: dual-instance frontend tooling, module-capability gating, and master/slave protocol self-healing fixes" (219/219 backend tests, 213/213 frontend tests, both green).
