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

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

🟢 CONSTRUCTION PHASE

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
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
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).
