# Audit Log — Local Dev Master/Slave Setup

## Initial Request — Feature Created

**Timestamp**: 2026-07-02T00:00:00Z

**User Input**: "Ik wil de tech-debt-backlog feature oppakken, maar ik wil ook nog iets erbij zetten zodat ik lokaal makkelijk een master en een slave cms kan laten draaien om de connectie tussen beide te kunnen testen"

**Follow-up clarification**: "Het is niet per se functioneel. Het is een run config die ik moet kunnen runnen op 2 verschillende poorten. De 1 met de master module en de andere niet. De slave moet allene het doel dienen de connectie op te zetten. De master moet de main CMS blijven waarin alle onderdelen gerunt en getest kunnen worden."

**AI Response**: "Besloten dit als aparte feature 'local-dev-master-slave-setup' te behandelen naast tech-debt-backlog, omdat het een losstaande dev-tooling/run-configuratie behoefte is (twee lokale instances op verschillende poorten — een met Modules.Master geladen, een zonder — om de master/slave connectie lokaal te kunnen testen) en geen tech-debt item. Taalvoorkeur: Engels voor documentatie, Nederlands voor gesprek."

**Context**: Feature aangemaakt; workspace detection uitgevoerd (brownfield, reverse-engineering artifacts uit `_shared/` hergebruikt). Volgende stap: Requirements Analysis.

## Conflict Detection

**Timestamp**: 2026-07-02T00:00:00Z

**User Input**: N/A (automated check)

**AI Response**: "⚠️ Potential Conflict Detected — feature 'local-dev-master-slave-setup' may affect components also touched by active feature 'tech-debt-backlog': shared component is Modules.Master. Resolution: developer handles at merge time; tech-debt-backlog's TD-001 (dead MasterModuleOptions properties) touches the same module this feature will add run configuration for — worth checking TD-001 isn't accidentally reintroduced when adding config for the second instance."

**Context**: Informational only, does not block progress.

## Requirements Analysis — Clarifying Questions Created

**Timestamp**: 2026-07-02T00:00:00Z

**User Input**: N/A (analysis step)

**AI Response**: "Investigated module loading (`ModuleOrchestrator.DiscoverModules` scans the build output folder for `SlpModularCms.Modules.*.dll` and loads every module found — no existing config toggle to exclude Master) and the existing Master/Slave connection mechanism (`Modules.Availability` already exposes the slave-side `MasterController`/`MasterAvailabilityService` used by any instance; `Modules.Master` is the master-side add-on with `CmsInstanceService`/`SlaveApiClient`). Created `inception/requirements/requirement-verification-questions.md` with 6 questions covering: module toggle mechanism, DB isolation, ports, launch method, frontend scope, and slave-registration approach — pre-filled with recommended answers (A) for the user to confirm or override."

**Context**: Requirements Analysis, Step 6 — awaiting user confirmation of clarifying questions before generating requirements.md.

---

## Requirements Analysis — Answers Received, Ambiguity Detected

**Timestamp**: 2026-07-03T00:00:00Z

**User Input**: "Ik heb de vragen beantwoord" — answers recorded in `requirement-verification-questions.md`: Q1=X (separate project sufficient for testing, but also wants a future production model of base API + drop-in module DLLs), Q2=A, Q3=A, Q4=A, Q5=B (frontend should also run against slave), Q6=A (manual, explicitly to test the Add CMS Instance UI flow).

**AI Response**: "Detected scope ambiguity in Q1 — it mixes a local-dev-only need (separate test host project without Modules.Master) with a much larger production packaging/deployment change (restructuring SlpModularCms.Api.csproj to not directly reference module projects, loading module DLLs from a drop-in folder at runtime). Created `requirement-verification-clarification-questions.md` asking whether to keep this feature scoped to local dev only (deferring the production plugin model to a future feature), expand scope to implement the production drop-in-DLL model now, or use the simpler config-driven Modules:Disabled toggle instead."

**Context**: Requirements Analysis, Step 6 — awaiting clarification before generating requirements.md. Other answers (Q2-Q6) accepted as-is, no further ambiguity detected there.

---

## Requirements Analysis — Clarification Resolved

**Timestamp**: 2026-07-03T00:00:00Z

**User Input**: "ik heb de vraag beantwoord" — Clarification Question 1 answered A: keep this feature scoped to local dev only (separate `SlpModularCms.Api.Slave` test host project, no `Modules.Master` reference); defer the "base API + drop-in module DLLs for production" idea to a future feature.

**AI Response**: "Scope confirmed. Proceeding to generate requirements.md with: separate slave host project, separate local databases per instance, master keeps existing ports (5284/7221) and slave gets 5285/7222, two `dotnet run --launch-profile` invocations to start both, frontend also configurable to point at the slave, and manual slave registration via the existing Add CMS Instance UI flow. The production drop-in-DLL plugin model is noted as explicitly out of scope / future work."

**Context**: Requirements Analysis, Step 6 gate passed — all ambiguities resolved. Proceeding to Step 7 (generate requirements.md).

---

## Requirements Analysis — Document Generated

**Timestamp**: 2026-07-03T00:00:00Z

**User Input**: N/A (generation step)

**AI Response**: "Generated `inception/requirements/requirements.md` with 4 functional requirements (slave-only host project `SlpModularCms.Api.Slave`, distinct launch/appsettings config per instance, frontend configurable against either instance, runbook documentation) and 4 non-functional requirements (no bootstrap-code duplication between host projects, DB isolation, local-only scope, secrets hygiene). Recorded the production drop-in-DLL plugin model as explicitly Out of Scope / future work per user's clarification answer."

**Context**: Requirements Analysis, Step 9 — presenting completion message, awaiting user approval before proceeding.

## Workflow Planning - Approval

**Timestamp**: 2026-07-03T00:00:00Z

**AI Prompt**: "Ready to proceed with this plan?"

**AI Response (plan summary)**: "Created `inception/plans/execution-plan.md`. Risk: Low. Recommended: EXECUTE Application Design (minimal — decide shared bootstrap extraction between master/slave hosts) and Units Generation (2 units: Unit 1 Backend dual-instance hosting, Unit 2 Frontend dual-instance tooling & runbook); SKIP User Stories and, per-unit, Functional Design / NFR Requirements / NFR Design / Infrastructure Design (no new business logic, NFRs already captured, no infrastructure involved). Code Generation and Build and Test always execute."

**User Response**: "Approve & Continue naar Workflow Planning" (approval for Workflow Planning stage received prior to plan presentation; awaiting explicit approval of this execution plan next)

**Status**: Plan created, awaiting user approval

**Context**: Workflow plan created with 4 stages to execute in Inception (Workflow Planning, Application Design, Units Generation) + Construction (2 units, Code Generation, Build and Test)

## Application Design — Plan Created

**Timestamp**: 2026-07-03T00:00:00Z

**User Input**: N/A (planning step)

**AI Response**: "Investigated `ModuleOrchestrator`/`ServiceCollectionExtensions`/`ApiPrefixConvention` — all public, all depend only on `SlpModularCms.Core.*` namespaces, none reference `Modules.Master`/`Modules.Identity`/`Modules.Availability` directly, confirming they can be extracted into a shared project. Created `inception/plans/application-design-plan.md` with 2 questions (extraction approach, shared project name/dependencies), pre-filled with recommended answers (A: new `SlpModularCms.Api.Hosting` class library referencing only `SlpModularCms.Core`, referenced by both host projects)."

**Context**: Application Design, Step 6 — awaiting user confirmation of plan questions before generating design artifacts.

---

## Application Design — Answers Received, Contradiction Detected

**Timestamp**: 2026-07-03T00:00:00Z

**User Input**: "Ik heb de vragen beantwoord, ga door" — Q1=C (MSBuild file-linking, wants "1 buildable project for production... no extra overhead for testing"), Q2=B (move shared code directly into existing `SlpModularCms.Core` project instead of a new project).

**AI Response**: "Detected that Q1 (file-linking) and Q2 (move into Core) are two different, mutually exclusive solutions to the same problem. Verified `SlpModularCms.Core.csproj` already has a `FrameworkReference` to `Microsoft.AspNetCore.App` plus JwtBearer/Identity EF packages, so moving the three classes into Core needs only two additional package references (`Asp.Versioning.Mvc`, `Microsoft.AspNetCore.OpenApi`) and no file-linking at all — B fully achieves the user's stated goal (one buildable copy, no overhead) better than C. Created `application-design-clarification-questions.md` asking the user to confirm B supersedes C."

**Context**: Application Design, Step 9 — awaiting clarification before generating design artifacts.

## Application Design — Contradiction Resolved

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: "Ja, A is correct, ga door"

**AI Response**: "Confirmed: move ModuleOrchestrator, ServiceCollectionExtensions, and ApiPrefixConvention into SlpModularCms.Core (new namespace SlpModularCms.Core.Hosting), adding Asp.Versioning.Mvc and Microsoft.AspNetCore.OpenApi package references to Core. No new shared project, no file-linking. Proceeding to generate application design artifacts."

**Context**: Application Design, Step 9 gate passed. Proceeding to Step 10 (generate design artifacts).

## Units Generation — Plan Created

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: N/A (planning step)

**AI Response**: "Confirmed no dedicated test project exists for SlpModularCms.Api today (thin bootstrap code). Created inception/plans/unit-of-work-plan.md with 3 questions (confirm 2-unit split, confirm Unit 1 must be functionally complete before Unit 2 is meaningfully verified, confirm no dedicated test project needed for Api.Slave), pre-filled with recommended answers (A)."

## Code Generation — Unit 1 — Complete

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: N/A (generation step)

**AI Response**: "Executed all 6 plan steps: relocated ModuleOrchestrator/ServiceCollectionExtensions/ApiPrefixConvention into SlpModularCms.Core.Hosting (needed extra usings for Microsoft.Extensions.Configuration/DependencyInjection/AspNetCore.Builder/Http since Core is a plain Sdk project, not Sdk.Web); updated SlpModularCms.Api/Program.cs; created SlpModularCms.Api.Slave project (Core + Modules.Availability + Modules.Identity only, no Master) with its own appsettings/launchSettings (5285/7222) and added it to SlpModularCms.sln. Discovered SlpModularCms.Modules.Identity.Tests referenced SlpModularCms.Api solely to test the two relocated classes — relocated those tests to Core.Tests/Hosting/ and dropped the now-unneeded Api ProjectReference. Verified: dotnet build succeeds; dotnet test passes all 4 existing suites unchanged (54+60+37+42); manually ran both hosts and confirmed via logs that master discovers 3 modules (Availability, Identity, Master) while slave discovers exactly 2 (Availability, Identity) — Master correctly excluded. Wrote construction/unit-1-backend-dual-instance-hosting/code/summary.md."

## Code Generation Plan — Unit 2

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: N/A (planning step)

**AI Response**: "Verified via git check-ignore that frontend/.gitignore's existing *.local pattern already covers a new .env.slave.local file. Created construction/plans/unit-2-frontend-dual-instance-tooling-code-generation-plan.md with 4 steps: env files for slave mode, dev:slave npm script, runbook section in root README.md after 'Master CMS Module', documentation summary."

**Context**: All units complete. Starting Build and Test.

---

## Build and Test Stage

**Timestamp**: 2026-07-04T00:00:00Z

**Build Status**: Success

**Test Status**: Pass (193/193 automated; 1 manual integration scenario documented as developer follow-up — no local SQL Server available in this sandboxed session)

**Files Generated**:
- build-instructions.md
- unit-test-instructions.md
- integration-test-instructions.md
- build-and-test-summary.md

**AI Response**: "Ran dotnet build (success) and dotnet test (193/193 pass across 4 projects). Verified module isolation scenario manually (master loads 3 modules, slave loads 2, no Master). Documented the end-to-end Add CMS Instance connection scenario as a manual follow-up since no container runtime is available in this environment to provision a local SQL Server. Updated active-features.md to ✅ Complete (Operations is a placeholder for this project)."

**Context**: Build and Test complete. Presenting completion message, awaiting final approval.

---

## Build and Test — Change Requested (Recognizable Tab Titles)

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: "Geef de frontend van de slave een herkenbare html title zodta de tabbladen snel herkenbaar maken welk systeem ik bekijk"

**AI Response**: "Added VITE_APP_TITLE env var (optional, defaults to 'SlpModularCms'), wired into frontend/src/lib/config.ts (appTitle field) and set via document.title in main.tsx. Set VITE_APP_TITLE=SlpModularCms (Slave) in frontend/.env.slave.local and VITE_APP_TITLE=SlpModularCms (Master) in the developer's existing frontend/.env.local for symmetry. Updated frontend/.env.example and vite-env.d.ts. Verified: pnpm build succeeds (tsc + vite build), pnpm test 208/209 pass — the 1 failure (AddCmsInstanceDialog.test.tsx timeout) reproduced as a flaky test unrelated to this change (passed 5/5 in isolation). Updated Unit 2's code summary."

**Context**: Small addition to Unit 2 scope during Build and Test review. Re-presenting Build and Test completion message.

---

## Build and Test — Fix Requested (Slave Connection String)

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: "Ik denk dat de connectionstring niet goed is voor de Slave CMS. Maak van de appsettings.local.json.example een implementatie van de appsettings.local.json met dezelfde credentials, maar zijn eigen database"

**AI Response**: "Created the real (gitignored) src/SlpModularCms.Api.Slave/appsettings.local.json, mirroring the master's credentials (Server=127.0.0.1,1433;User ID=sa;...) with Database=SlpModularCmsSlave instead of SlpModularCms. Verified via git check-ignore it's untracked. Ran the slave with --no-build: it successfully connected to the local SQL Server, created the SlpModularCmsSlave database, and applied EF Core migrations — confirming the connection string now works (this environment does have a reachable local SQL Server at 127.0.0.1:1433, contrary to the earlier Build and Test assumption). Attempted to also run master simultaneously to redo the full end-to-end connectivity scenario, but hit 'address already in use' on both :7221 and :7222 from leftover dotnet run child processes surviving earlier timeout-wrapped manual test invocations in this session — a session artifact, not a code defect. Did not force-kill processes broadly per sandbox safety controls; flagged for the user to clear stray processes before their own manual verification. Updated Unit 1's code summary with these findings."

**Context**: Connection string issue resolved and verified via actual DB/migration success. Full simultaneous master+slave connectivity test still pending due to a leftover-process port conflict in this session, not a code issue.

---

## Port Conflict — Resolved

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: "ik heb mijn processen afgesloten. jij mag jouwe afsluiten"

**AI Response**: "Checked via Get-CimInstance for any SlpModularCms-named processes (none found) and via Get-NetTCPConnection for ports 7221/7222/5284/5285 (none listening) — no leftover processes remain on either side; ports are free."

**Context**: Environment clean. Ready for the user to perform their own manual end-to-end master+slave connectivity verification whenever convenient.

---

## Migration Status Check — Gap Found and Fixed

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: "Zijn de nodige migraties gemaakt en zijn beide databases up-to-date?"

**AI Response**: "Checked all DbContext/startup-project combinations via 'dotnet ef migrations list' (read-only). Master DB (SlpModularCms) fully up to date across ApplicationDbContext (Core/Identity), AvailabilityDbContext, and MasterDbContext. Slave DB (SlpModularCmsSlave) had AvailabilityDbContext applied (auto-migrated on startup) but ApplicationDbContext (Core/Identity) had 2 pending migrations — Core's Identity migrations are never auto-applied (only Availability and Master modules call Database.Migrate() in UseModule), and nobody had run the manual dotnet ef database update for the new slave DB yet. Fixed by running 'dotnet ef database update --project src/SlpModularCms.Core --startup-project src/SlpModularCms.Api.Slave --context ApplicationDbContext' — both migrations now applied, verified via a follow-up migrations list showing no pending entries. Added this exact command to the README runbook so it isn't missed again in the future. Updated Unit 1's code summary with the full before/after migration status table."

**Context**: Both databases now confirmed fully up to date across all applicable DbContexts. Runbook documentation updated to prevent recurrence.

---

## Fix — CMS Page Wrongly Visible on Slave

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: "De front-end van de Slave toont nog steeds de CMS-pagina. Deze is dus alleen voor de Master. De CMS-en zonder de Master-module mogen die pagina niet zien"

**AI Response**: "Dispatched an Explore subagent to map how /cms visibility currently works — found it was gated purely by Owner role (router.tsx cmsRoute, Sidebar.tsx NAV_ITEMS), with zero awareness of whether the connected backend actually has Modules.Master loaded (never an issue before this feature, since every instance always had it). Implemented a backend capability check: ModuleOrchestrator.ModuleNames property, new SystemController exposing GET /api/v1/System/capabilities, orchestrator registered as a DI singleton in both Program.cs files. Frontend: useSystemCapabilities hook, new ModuleGuard component (mirrors RoleGuard), applied to both the /cms route and the Sidebar nav item requiring the 'Master' module. Added MSW mock handler (defaults to including Master, so existing tests are unaffected) and i18n strings. Verified: dotnet build/test all pass (193/193); pnpm build succeeds; pnpm test 210/210 in isolation (one pre-existing flaky test in the full run, unrelated). Live-verified against actually running master and slave instances — curled the new endpoint directly: master returns ['Availability','Identity','Master'], slave returns ['Availability','Identity'] only. Cleaned up the two verification processes by their specific PIDs afterward. Documented in a new master-only-cms-page-fix.md under Unit 2's code folder."

**Context**: Genuine functional gap surfaced by this feature (frontend had no way to know backend module composition) now fixed and verified end-to-end, not just conceptually.

---

## Fix — CMS Instance Status Badge Styling & Master-Gate Status Not Reflected on Slave

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: "1: De badge die getoond wordt op de CMS-pagina toont beschikbaar in grijs in plaats van in groen en zonder icoontje. Laat die badge hetzelfde werken als op de availability op de dashboard. Inactive mag wel grijs zijn. 2: Als ik de status van een slave verander gebeurd er niks en er wordt ook geen call gedaan naar de slave om de status te veranderen. Was dit niet wat er was afgesproken dat er zou gebeuren als de master de status veranderd? Als ik naar de slave ga blijft die Beschikbaar ongeacht of de master hem heeft ingesteld op Niet beschikbaar. Ook na refresh en re-login"

**AI Response**: "Fix 1 (badge styling): frontend/src/components/cms/CmsInstanceList.tsx used a plain shadcn Badge (variant-based, no color/icon for Available) instead of the colored-pill + icon pattern used by AvailabilityStatusBadge on the dashboard. Replaced it with the same visual pattern: green+CheckCircle for Available, red+XCircle for NotAvailable, grey+MinusCircle for Inactive (as requested, Inactive stays grey). Fix 2 (master status not reaching slave dashboard): confirmed CmsInstanceService.UpdateStatusAsync (Modules.Master) does correctly call SlaveClient.PushStatusAsync, which does reach MasterController/MasterAvailabilityService.PushStatusAsync (Modules.Availability) on the slave and updates its in-memory MasterGateStatus. However, that master-gate status was only ever consulted by AvailabilityMiddleware to gate/503 *other* API calls — the dashboard's own availability badge queries GET /api/v1/Availability/status, which is deliberately bypassed by the middleware (so admins can still log in and see the app) and is backed by PersistentAvailabilityService, which never looked at the master gate at all. So the push from master WAS working, but its effect was invisible on the slave's own dashboard. Fixed by injecting IMasterAvailabilityService into PersistentAvailabilityService and having GetStatusDetailsAsync() return NotAvailable + the master's disableMessage whenever the master gate reports unavailable, falling back to the locally persisted status otherwise. Added a regression test (GetStatusDetailsAsync_ShouldReturnNotAvailable_WhenMasterGateDisabled) and updated two existing test call sites for the new constructor parameter. Verified: dotnet test on Modules.Availability.Tests — 61/61 pass; pnpm build succeeds; pnpm test — 210/210 pass (no flaky failures this run)."

**Context**: Fix 2 was a real functional gap in the master/slave feature's core promise (this feature exists specifically to let the master's status changes be observable on the slave) — not a new capability, but completing what 'master pushes status to slave' was always supposed to mean end-to-end.

---

## Feature — Combined `pnpm dev:all` Script for Frontend

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: "Kan je voor de front-end een script toevoegen waarmee ik in 1x master en slave kan opstarten. Beetje zoals ik in Rider de Compound configuratie heb"

**AI Response**: "Added 'dev:all' script to frontend/package.json using the new 'concurrently' devDependency: runs 'pnpm dev' (master, :5173) and 'pnpm dev:slave' (slave, :5174) in parallel in one terminal, each line prefixed and colored (blue/magenta) so output stays distinguishable — analogous to a Rider Compound run configuration. Ctrl+C stops both. Verified by actually running 'pnpm dev:all' for ~10s: both Vite dev servers started correctly on their expected ports with correctly labeled/colored output. Updated README with the new command under 'Frontend starten'."

**Context**: Pure dev-ergonomics addition, no behavior change to the app itself.

## Bug Report — Slave Shows Available After Restart Despite Master Having Disabled It

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: "Als ik de master en slave opnieuw opstart dan zegt de slave dat hij beschikbaar is terwijl de master aangeeft dat die onbeschikbaar zou moeten zijn. Hoe komt dat?"

**AI Response**: "Root cause: the slave's master-gate status (MasterAvailabilityService._masterIsAvailable / _masterDisableMessage) is held in static in-memory fields only — never persisted — defaulting to available=true on every process start. The master's CmsInstance.Status IS correctly persisted in its own DB, but nothing re-pushes that persisted status to the slave on startup; a push only happens when an admin explicitly changes status via the UI (CmsInstanceService.UpdateStatusAsync). The existing periodic IntegrityCheckBackgroundService (default: every 60 minutes) only re-verifies/re-registers the slave's registered master URL in VerifyIntegrityAsync — it never re-pushed status, so even the periodic reconciliation wouldn't have caught this within a reasonable time. Fixed both halves: (1) CmsInstanceService.VerifyIntegrityAsync now also re-pushes the master's persisted status (SlaveClient.PushStatusAsync) to every active slave on each integrity check, so a slave that resets to 'available' on restart gets corrected; (2) IntegrityCheckBackgroundService.ExecuteAsync now runs one check immediately on startup instead of waiting for the first PeriodicTimer tick, so this resync happens right after the master (re)starts rather than up to 60 minutes later. Added a regression test (VerifyIntegrityAsync_RePushesPersistedStatus_ToResyncSlaveAfterRestart). Verified: dotnet test on Modules.Master.Tests — 43/43 pass (was 42)."

**Context**: This is the same underlying gap as the earlier CMS-badge/master-gate fix (in-memory state on the slave not being kept in sync with the master's persisted intent), surfacing again specifically around process restarts rather than live status pushes.

## Question — Refresh Tokens Overwritten Between Master and Slave Frontends

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: "Ik kan niet op beide systemen ingelogd zijn. De refresh tokens wordne overschreven. Is dat iets vanwege het lokaal draaien? [...] ik gok dat dat aan de hand van domein is wat lokaal allebei localhost is, klopt dat?"

**AI Response**: "Confirmed the user's hypothesis. AuthController.GetCookieOptions() sets the refreshToken cookie without an explicit Domain, so it's host-scoped to whichever host issued it — but per RFC 6265, cookies are never port-scoped, only domain+path. Master (localhost:7221) and slave (localhost:7222) both set 'refreshToken' for domain 'localhost', path '/api/v1/auth' — identical cookie key, so the last login always overwrites the other. In production this isn't an issue since each CMS instance has its own real domain (properly separated by the browser's cookie jar); this is purely a local-dev artifact of both instances happening to share the 'localhost' hostname. Offered two workarounds (hosts-file entries like master.local/slave.local for a production-like separation, or simply using separate browser profiles/incognito for master vs slave) without recommending any code change, since this isn't a defect."

**Context**: User confirmed the incognito-workaround is sufficient; no code change made. Not a bug — purely local-dev cookie-domain behavior, explicitly ruled out as something to fix in the app.

## Fix — Slave Stuck on Last Pushed Status After Master Sets It to Inactive

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: "Wat ik wel zie is dat de slave op 'Niet Beschikbaar' blijft staan als ik hem in de Master van 'Niet beschikbaar' naar 'Inactief zet'. Als de Master de Slave niet meer beheert moet de Slave gewoon weer Beschikbaar worden. Zat er niet al een systeem in dat Slave bij Master kijkt wat de status is? Daar zouden we het bij kunnen zetten. Ik weet ook niet of dat een periodieke check is?"

**AI Response**: "Confirmed there is no slave-polls-master mechanism at all — the master/slave protocol is entirely push-based from the master side (explicit status pushes on UpdateStatusAsync, plus the periodic IntegrityCheckBackgroundService discussed in the prior fix). Root cause of this specific report: CmsInstanceService.UpdateStatusAsync had an early-return for CmsInstanceStatus.Inactive that skipped SlaveClient.PushStatusAsync entirely ('master no longer manages this slave' was implemented as 'do nothing'), so the slave kept whatever gate state (e.g. NotAvailable) it was last pushed, forever — and since VerifyIntegrityAsync's periodic resync only iterates GetActiveAsync() (which excludes Inactive instances), it would never self-correct either. Fixed by having the Inactive branch explicitly push isAvailable=true, disableMessage=null to the slave — releasing the master gate — before returning, mirroring the same release-on-deactivation logic. Updated the existing UpdateStatusAsync_DoesNotPushToSlave_WhenStatusIsInactive test (renamed/inverted to UpdateStatusAsync_ReleasesMasterGate_WhenStatusIsInactive) and added UpdateStatusAsync_ReturnsSlaveContactFalse_WhenReleasingMasterGateFails. Verified: dotnet test on Modules.Master.Tests — 44/44 pass (was 43)."

**Context**: Third fix in this feature's 'slave in-memory master-gate state must stay in sync with the master's actual intent' theme — this one specifically for the deactivation/detach path, which had simply never pushed anything to the slave at all.

## Feature — Slave Pull-Based Status Polling with Fail-Open

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: "volgens mij was het idee dat de slave ook af en toe bij de master vroef wat de status is zodat lokaal niet de boel zomaar kan worden aangepast en dat de slave af en toe een refreh doet van de status. ook weer om dit soort issues tegen te gaan. Als de master te lang onbeschikbaar is of gewoon niet reageert moet de slave beschikbaar worden zodat het een fail-open is"

**AI Response**: "Dispatched an Explore subagent to check whether this was ever actually specified. Confirmed: the original master-cms-module inception requirements (FR-MASTER-06 'Slave Pull Model: Periodic Master Check', FR-MASTER-07 'Slave Fallback Behavior', NFR-MASTER-01 'Fail-Open Safety') explicitly called for a slave-initiated periodic pull with fail-open, but the later construction-phase design silently switched to a push-only model (master calls slave), keeping only the in-memory fail-open *default* (true on process start) rather than an active reconciling pull. Implemented the originally-specified pull side to complement (not replace) the existing push: (1) new master-side GET /api/v1/SlaveStatus endpoint (SlaveStatusController + ICmsInstanceService.GetStatusForApiKeyAsync), authenticated by matching the caller's plain API key against each active CmsInstance's decrypted key — added to AvailabilityMiddleware's bypass list so it's always reachable regardless of the master's own local status; (2) slave-side MasterStatusPollingBackgroundService (Modules.Availability), polling on a configurable interval (MasterPollingOptions, default 30s / 15s in dev) via new IMasterStatusPollClient, applying successful results through new IMasterAvailabilityService methods (GetPollTargetAsync, ApplyPolledStatusAsync); (3) fail-open: RecordPollFailureAsync forces the gate back to Available if the master has been unreachable for longer than FailOpenAfterMinutes (default 5min / 2min in dev), measured from MasterRegistration.LastPolledAt (new persisted field, new EF migration AddLastPolledAtToMasterRegistration, applied to both master and slave DBs). The existing push mechanism is untouched and still fires instantly on explicit status changes; polling is the self-healing safety net for everything push can miss (restarts, dropped pushes, local tampering). Verified: dotnet test across the whole solution — 216/216 pass (75 Availability + 50 Master + 54 Core + 37 Identity). Live smoke-tested by starting both master and slave: confirmed the new background service starts without crashing the host, correctly detects a connection failure (mismatched port in this quick ad-hoc run, not a code issue) and handles it gracefully through the fail-open path rather than an unhandled exception."

**Context**: This closes a real design regression: the pull+fail-open behavior was part of the original spec but got dropped during construction without anyone flagging it, and its absence was the root cause behind several of today's earlier reports (slave stuck on stale status after restart, after deactivation). Push and pull now both exist and complement each other.

## Fix — Slave Settings Silently Accepted (and 'Succeeded') Local Availability Changes While Master-Controlled

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: "Als de Slave op 'Niet beschikbaar' is gezet door de master en je probeert in de instellingen van de slave het systeem op beschikbaar te zetten dan krijg je wel een succesmelding. dat moet een adere mrlding worden, maar eigenlijk moet je helemaal de beschikbaarheid niet moeten kunnen veranderen in de instellingen en je moet daar dan een melding zien waarom"

**AI Response**: "Root cause: PersistentAvailabilityService.UpdateStatusAsync always wrote the requested status to the local DB unconditionally, while GetStatusDetailsAsync (fixed earlier today) displays the master-gate status whenever the master has disabled the instance — so a local admin's 'Available' write was accepted and even reported as a DB update, but instantly invisible/overridden on the very same GET that renders the Settings page, giving a false success toast for a change that had no observable effect. Fixed by rejecting the change outright instead of silently no-op'ing it: (1) new MasterControlledAvailabilityException (Core.Availability), thrown by PersistentAvailabilityService.UpdateStatusAsync when IMasterAvailabilityService.GetMasterStatus().IsAvailable is false, before touching the DB; (2) AvailabilityController.UpdateStatus catches it and returns 409 Conflict with a ProblemDetails body; (3) AvailabilityStatusDetails gained an IsMasterControlled flag (true whenever GetStatusDetailsAsync short-circuits on the master gate), now included in GET /api/v1/Availability/status; (4) frontend SettingsPage.tsx reads availability.isMasterControlled and disables the mode buttons, the reason textarea, and the save button, showing a locked-state banner explaining that the Master CMS controls this status; a 409 from the mutation (e.g. a race where master disables it mid-edit) shows a specific 'Master CMS controls this status' toast instead of the generic error. Verified: dotnet test — 219/219 pass across the solution (78 Availability, up from 75); pnpm build succeeds; pnpm test — 213/213 pass (up from 210, 3 new SettingsPage tests covering the locked banner, the unlocked default state, and the 409 toast)."

**Context**: Same root theme as the day's earlier fixes (slave-side local state must never silently diverge from the master's actual intent) — this time the gap was a misleading UI: an operation appeared to succeed while being fully overridden, which is worse than an operation that visibly fails.

## Final Verification — README Addition + Full AI-DLC Documentation Cross-Check

**Timestamp**: 2026-07-04T00:00:00Z

**User Input**: "ja zet het erbij en check alles ook tegenover de aidlc documentatie" (following "Volgens mij werkt alles nu zoals verwacht. Doe nog 1 check of functionaliteit overeenkomt met de documentatie en of de tests slagen" and a prior note that the master-controlled-lock UI wasn't mentioned in the README)

**AI Response**: "Added a README section documenting the master-controlled Settings lock (banner, disabled controls, 409 on a bypass attempt, IsMasterControlled field). Then cross-checked the actual master/slave protocol documentation in aidlc-docs/features/master-cms-module/ (the feature that originally built the protocol this session's fixes touched) against the real as-built code — full details logged in that feature's own audit.md, since the corrections landed in its docs, not this feature's. Summary: found and fixed several actively-contradicted statements about Inactive-transition push behavior, VerifyIntegrityAsync's scope, and the master-gate cache's 'no expiry' claim; added new rule-set/flow sections for the slave-pull and master-controlled-lock mechanisms; flagged (via banners, not full rewrite) a larger pre-existing divergence between inception-stage application-design docs and what construction actually built, unrelated to today's changes. Also caught and fixed a real (if minor) config-consistency gap of my own: the new MasterPolling section had only been added to appsettings.Development.json, not the base appsettings.json for either Api or Api.Slave — added there too for both. Re-ran the full solution build + test suite after all changes: 219/219 backend, 213/213 frontend, all green."

**Context**: Closing verification pass for today's whole run of fixes (badge styling, master-controlled availability, slave restart resync, Inactive gate release, slave-pull/fail-open, master-controlled settings lock) — confirms the implementation, its tests, and its documentation are now mutually consistent.
