Adds SlpModularCms.Api.SlpSoftware and extracts shared CmsHost composition

Unit 1 of the slpsoftware-api feature (FR-1/FR-2/FR-3): a new Client project in the Clients solution folder, intended to eventually become the deployed API for test.slpsoftware.nl/slpsoftware.nl, hosting the same four modules as SlpModularCms.Api plus a future Offerings module. - Extracts SlpModularCms.Api/Program.cs's hosting-pipeline composition into SlpModularCms.Core.Hosting.CmsHost (ConfigureServices/ConfigurePipeline), shared by both Client projects so they cannot drift apart - Moves StaticContentExtensions.cs + WebsitePlaceholder.html from Api into Core, since CmsHost cannot live in Api but Core cannot depend on Api - Adds SlpModularCms.Api.SlpSoftware with its own isolated local dev database and dev ports (5286/7223, distinct from Api's and Api.Slave's) - Adds SlpModularCms.Api.Tests with WebApplicationFactory-based pipeline regression tests (security headers, health check, SPA fallback, rate limiting), scoped to Api per NFR Design - Adds a frontend dev:slpsoftware pnpm script mirroring dev:slave - Fixes GlobalExceptionHandler logging routine 401s (e.g. an expired/missing refresh token) as unhandled errors -- pre-existing, unrelated to this feature's own scope, found while testing the new instance Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FWyStNL2ZsjrS7FLd7xvvN

+# AI-DLC State Tracking
+
+## Project Information
+- **Feature Name**: SlpSoftware Production API
+- **Feature Slug**: slpsoftware-api
+- **Project Type**: Brownfield
+- **Start Date**: 2026-08-01T00:00:00Z
+- **Current Stage**: CONSTRUCTION - Unit 1 "SlpSoftware Client Setup" - Code Generation complete
+- **Branch**: master (no feature branch created yet)
+
+## Workspace State
+- **Existing Code**: Yes
+- **Reverse Engineering Needed**: No — existing `_shared/reverse-engineering/` artifacts (2026-07-27) judged current enough for this feature's scope. The only more recent commit is a frontend-only folder restructure, unrelated to this feature.
+- **Workspace Root**: K:\Development\Projects\SlpModularCms
+
+## Reverse Engineering Status
+- [x] Reverse Engineering — Reused existing artifacts, no rerun
+- **Artifacts Location**: aidlc-docs/_shared/reverse-engineering/
+- **Known staleness**: architecture.md still says "No CI/CD exists yet" — superseded by the (merged) `gitea-deployment-workflow` feature. Not relevant to this feature's own scope; verified the actual current `.gitea/workflows/*.yaml` directly instead of relying on that doc.
+
+## Code Location Rules
+- **Application Code**: Workspace root (NEVER in aidlc-docs/)
+- **Feature Documentation**: aidlc-docs/features/slpsoftware-api/ only
+- **Shared Artifacts**: aidlc-docs/_shared/
+- **Structure patterns**: See code-generation.md Critical Rules; also `CLAUDE.md` / `AGENTS.md` solution-structure rules (Application/Modules, Tests/Modules, Clients)
+
+## Language Configuration
+- **Documentation Language**: English
+- **Conversation Language**: User Language (Dutch)
+- **Note**: Defaulted to Option A (matches every other feature in this workspace); not re-asked via question file. User may override at any time.
+
+## External Reference (read-only, do not modify)
+- **Workspace**: K:\Development\SlpSoftware\Projects\SlpSoftware
+- **Handoff doc**: aidlc-docs/features/react-frontend/construction/react-frontend-app/functional-design/packages-api-handoff.md
+- **Constraint**: This workspace is reference-only for this feature. No file in it may be created/edited/deleted unless the user explicitly asks.
+
+## Extension Configuration
+| Extension | Enabled | Decided At |
+|---|---|---|
+| Security Baseline | Yes | Requirements Analysis |
+| Property-Based Testing | No | Requirements Analysis |
+
+## Operations Configuration
+- **Include Operations Phase**: Yes
+- **Decided At**: Requirements Analysis
+- **Note**: Per Q7, Operations phase for this feature includes retargeting the existing `gitea-deployment-workflow` CI/CD pipeline to `SlpModularCms.Api.SlpSoftware` (extend, do not duplicate) — see requirements.md NFR-Deploy section.
+
+## Potential Conflicts (from Workspace Detection)
+- **gitea-deployment-workflow** (status: 🟡 Operations, Production Readiness Validation still pending) — owns the CI/CD deploy pipeline (`.gitea/workflows/deploy-scp.yaml`, `continuous_integration.yaml`) and `operations/deployment/deployment-instructions.md`, all currently wired to `SlpModularCms.Api`. This feature's eventual deploy-retarget will need to touch that same pipeline. Resolution: coordinate at Workflow Planning / Operations time; do not duplicate that feature's Deployment Setup artifacts, extend them.
+- **tech-debt-backlog** (status: 🔵 Inception) — touches `Modules.Master`, `Frontend`. Overlap is informational only; no action needed unless real conflicts surface during Code Generation.
+
+## Execution Plan Summary
+- **Total Stages**: 3 remaining Inception stages (Application Design, Units Planning, Units Generation), 6 Construction stages (per unit), 3 Operations stages
+- **Stages to Execute**: Application Design, Units Planning, Units Generation, Functional Design (per unit), NFR Requirements (per unit), NFR Design (per unit), Infrastructure Design (per unit), Code Generation (always), Build and Test (always), Deployment Setup, Monitoring Setup, Production Readiness Validation
+- **Stages to Skip**: None at the feature level — per-unit Construction stages will be individually assessed (e.g. Functional Design/Infrastructure Design likely skip for a pure hosting-extraction unit) once Units Generation defines the actual units. See `inception/plans/execution-plan.md` for full rationale.
+
+## Stage Progress
+### INCEPTION
+- [x] Workspace Detection — Complete
+- [x] Requirements Analysis — Complete
+- [x] User Stories — Complete
+- [x] Workflow Planning — Complete
+- [x] Application Design — Complete
+- [x] Units Planning — Complete
+- [x] Units Generation — Complete (2 units: "SlpSoftware Client Setup", "Offerings")
+
+### 🟢 CONSTRUCTION PHASE
+
+#### Unit 1: SlpSoftware Client Setup
+- [x] Functional Design — **SKIPPED** (no new data model/business rules — pure hosting-composition extraction)
+- [x] NFR Requirements — Complete (new pipeline-level regression tests required; `CmsHostOptions` added, must never touch the Data Protection discriminator)
+- [x] NFR Design — Complete (regression tests scoped to `Api` only; `CmsHostOptions` stays an empty placeholder for now)
+- [x] Infrastructure Design — Complete (cutover target documented: same Pi/systemd units/ports/DB, only the deployed `.dll` changes at Operations time; `Api.SlpSoftware` gets its own isolated local dev database)
+- [x] Code Generation — Complete (build succeeded after 2 fixes; Core.Tests 196/196, new Api.Tests 4/4)
+
+#### Unit 2: Offerings
+- [ ] Functional Design
+- [ ] NFR Requirements
+- [ ] NFR Design
+- [ ] Infrastructure Design
+- [ ] Code Generation
+
+#### Feature-wide
+- [ ] Build and Test — EXECUTE (ALWAYS, after both units complete)
+
+### 🟡 OPERATIONS PHASE
+- [ ] Deployment Setup — EXECUTE
+- [ ] Monitoring Setup — EXECUTE
+- [ ] Production Readiness Validation — EXECUTE (ALWAYS, once phase reached)
+
+## Current Status
+- **Lifecycle Phase**: CONSTRUCTION
+- **Current Stage**: Unit 1 "SlpSoftware Client Setup" — Code Generation complete

+## Workspace Detection
+
+**Timestamp**: 2026-08-01T00:00:00Z
+
+**User Input**: "Ik wil een nieuwe API toevoegen als CMS voor SlpSoftware. De huidige API is de Master API en vooral voor development handig. Ik wil in de Clients Solution Folder een nieuwe API `SlpModularCms.Api.SlpSoftware`. Deze API moet de Master module bevatten en deze API moet uiteindelijk de API worden die wordt gedeployed naar test.slpsoftware.nl en slpsoftware.nl in plaats van de huidige master API `SlpModularCms.Api`. Voor de nieuwe API wil ik ook een nieuwe module toevoegen gebaseerd op wat de website nodig heeft. Dat is vastgelegd in `K:\Development\SlpSoftware\Projects\SlpSoftware\aidlc-docs\features\react-frontend\construction\react-frontend-app\functional-design\packages-api-handoff.md`. Je mag ook in de workspace zelf kijken als er iets onduidelijk is `K:\Development\SlpSoftware\Projects\SlpSoftware`, maar je mag NIKS veranderen in die workspace tenzij ik dat aangeef of vraag. Start een nieuwe aidlc workflow voor deze feature. Is het helemaal duidelijk?"
+
+**AI Response**: "Confirmed understanding in chat, then invoked the aidlc-workflow skill. Ran Workspace Detection: found existing multi-feature workspace (`active-features.md`), reverse-engineering artifacts present and judged current for backend-architecture purposes (dated 2026-07-27; the only more-recent commit, `11ec08a`/`dcc82cd`, is a frontend-only folder restructure unrelated to this feature's scope). Read the external handoff doc (read-only) at the path given: scope is a single public `GET /api/v1/packages` endpoint (no auth, no mutation) backing the marketing site's 'Drie manieren om te starten' package cards, with seed content available in that workspace's `content.ts`. Cross-checked against this repo's own `WEBSITE_WORKSPACE.md` and the already-merged `gitea-deployment-workflow` feature: the public website (`test.slpsoftware.nl` / `slpsoftware.nl`) is already served same-origin out of `wwwroot/web/` by whichever Client API is deployed, with `/api/v1` already same-origin — so the handoff doc's 'nginx proxy_pass' open item is likely already moot under this repo's existing hosting model, pending confirmation. Selected feature slug `slpsoftware-api` (new feature, per explicit user instruction — no existing active feature matches this scope). Flagged potential overlap with two in-flight/related features: `gitea-deployment-workflow` (Operations phase, not yet fully closed out — owns the CI/CD deploy pipeline and deployment-instructions that currently target `SlpModularCms.Api`) and `tech-debt-backlog` (Inception phase — touches `Modules.Master`)."
+
+**Context**: Workspace Detection stage. Brownfield project. Multi-feature workspace. Proceeding to Requirements Analysis (reverse-engineering artifacts present and current enough; no rerun performed).

+## Requirements Analysis — Clarifying Questions Created
+
+**Timestamp**: 2026-08-01T00:05:00Z
+
+**User Input**: N/A (no new user input this step; proceeding per approved workflow)
+
+**AI Response**: "Intent analysis: New Feature, Multiple Components scope (new Client API project, new module + tests, potential CI/CD retarget), Complex (touches solution structure, an in-flight Operations-phase feature's deploy pipeline, and a cross-workspace content contract) -> Comprehensive depth. Verified via direct inspection (not just RE docs): the `.sln` NestedProjects section shows the `Clients` solution folder currently has zero projects nested under it, while `SlpModularCms.Api`/`Api.Slave`/`Core`/`Modules` all sit under `Application` -- confirming CLAUDE.md's structure already anticipates this feature. Confirmed `SlpModularCms.Api.csproj` references Core+Availability+Identity+Master and `Program.cs` composes a non-trivial hosting pipeline (built during `gitea-deployment-workflow`). Read the external handoff doc (read-only): scope is a single public unauthenticated `GET /api/v1/packages`, plus its `domain-entities.md`/`business-rules.md` for the `PackageCard` field list and BR-4 content-fidelity rule. Cross-checked its 'missing nginx proxy_pass' open item against this repo's own `WEBSITE_WORKSPACE.md` and found it likely already moot under the existing same-origin hosting model -- flagged as a question rather than assumed. Created `inception/requirements/requirement-verification-questions.md` with 13 questions across 7 sections: (A) Api vs Api.SlpSoftware relationship and pipeline-code duplication, (B) new module scope against the handoff doc, (C) deploy-retarget timing and Api's long-term fate, (D) module naming/DbContext isolation, (E) Security Baseline extension opt-in, (F) Property-Based Testing extension opt-in, (G) Operations phase inclusion."

+
+**User Input**: "Ga verder met de aidlc feature slpsoftware-api. ik heb de vragen beantwoord"
+
+**AI Response**: "Read `requirement-verification-questions.md`. All 13 questions answered. Analyzed for ambiguities per question-format-guide.md: 11 of 13 answers are clear and actionable as-is (Q1 A, Q2 A, Q3 A, Q4 B, Q6 A, Q7 A, Q8 A, Q10 A, Q11 A, Q12 C, Q13 A). Q5 (seed data) answer is a custom response ('x') that is actionable without further clarification: user will enter package content manually later, but wants the currently-live values preserved as documented reference data -- retrieved these directly from the external reference workspace's `src/features/landing/data/content.ts` (read-only access, as permitted) so they can be captured in requirements.md rather than lost. Q9 (module naming) answer is a custom response ('A, al lijkt het me iets te generiek...') that explicitly asks for additional name suggestions and reframes the module's intended scope as a generic, cross-tenant reusable 'service/offering package' concept (not tied to SlpSoftware specifically, with a stated future use case of a photography business selling photoshoot packages) -- this is a genuine open question requiring a follow-up round, not something safe to resolve unilaterally. Created `requirements-clarification-questions.md` with 1 follow-up question offering renamed alternatives reflecting the generic-offering framing."

+## Requirements Analysis — Requested Changes (Route Rename + Pipeline Cutover)
+
+**Timestamp**: 2026-08-01T00:25:00Z
+
+**User Input**: "de module heet Offerings, dus de api endpoint wil ik dat die dezelfde naam krijgt `/api/v1/offerings`\nIk weet niet of dat hier al nodig is om vast te leggen, maar SlpModularCms.Api wordt in de pipeline vervangen door de nieuwe API"
+
+**AI Response**: "Two changes requested. (1) Route rename from `/api/v1/packages` to `/api/v1/offerings` (resolves former Assumption A-1) creates a real dependency: the external reference workspace's `usePackagesQuery.ts` still fetches the old path, and that workspace is explicitly protected ('no changes unless you ask'). Asked the user via AskUserQuestion whether to also update that frontend fetch call, let them handle it separately, or revert to `/api/v1/packages`. User chose 'dat regel ik zelf' (handles it separately, out of scope for this feature). (2) Recorded as D-15: the Operations-phase CI/CD retarget (FR-9) is a cutover — `Api` replaced by `Api.SlpSoftware` as the pipeline's build/deploy target, not run side by side. Updated requirements.md: Decisions table (+D-14, +D-15), FR-6 (route + rewritten frontend-dependency note), FR-9 (cutover language, removed 'deferred' sequencing line), Security Compliance SECURITY-08 row (route text), Scope Boundaries (route + explicit frontend-fetch-path exclusion + cutover framing), Assumptions (A-1 marked resolved with strikethrough), summary counts (15 decisions, 1 open assumption)."

+
+**AI Response**: "Created `inception/plans/user-stories-assessment.md`: Execute = Yes, meets High Priority criteria (new user-facing admin feature, customer-facing API, multi-persona system). Created `inception/plans/story-generation-plan.md` with a 7-step checklist (personas, Site Visitor stories, CMS Administrator stories, acceptance criteria, persona-story mapping, INVEST self-check, save artifacts) and 6 embedded clarification questions: story breakdown approach, acceptance-criteria format, whether admin CRUD should enforce the 'exactly one featured' rule from the hand-off doc, whether deleting the last remaining offering should be blocked, the reorder interaction model for the FR-5 `DisplayOrder` field, and the admin persona's name."

+
+**AI Response**: "Analyzed all 6 answers per Step 9. Q1-Q4 are unambiguous and directly actionable. Q5 ('A en B') is not a contradiction — drag-and-drop and up/down buttons are not mutually exclusive (buttons commonly serve as an accessible/keyboard fallback alongside drag-and-drop); accepted as 'support both' without a follow-up round. Q6's conditional phrasing ('als we het nederlands willen houden') was resolved by checking the actual frontend codebase rather than assuming: `frontend/src/i18n/locales/nl/translation.json` already maps the `Administrator` role to the Dutch UI label 'Beheerder', and `en/translation.json` exists alongside it — i18n is already in place. Resolved without a follow-up question: the persona is documented as 'CMS Administrator' (English documentation, per Documentation Language policy) with an explicit note that the existing i18n setup already renders this as 'Beheerder' in the Dutch-locale UI, satisfying the user's intent without contradicting the English-artifact convention used throughout this feature's docs. No ambiguities required blocking follow-up questions; proceeding to plan approval."

+**User Input**: N/A (no new user input this step; proceeding per approved workflow)
+
+**AI Response**: "Loaded requirements.md and stories.md/personas.md as prior context. Detailed analysis: Transformation Type = architectural addition (new Client project + module + a hosting-pipeline extraction, no deployment-model change); Risk Level = Medium (multiple components but each independently testable, highest-risk step — the CI/CD cutover — isolated to Operations and coordinated with the owning feature rather than forked). Component relationship diagram created showing Core as the shared foundation for both Api (unchanged) and the new Api.SlpSoftware, with Offerings only hosted by the new client, and the Gitea pipeline retargeted only in Operations. Module Update Strategy: Core extraction first (critical path, must not regress Api), then Api.SlpSoftware + Offerings in parallel, then the Operations-phase pipeline cutover last. Execution plan: Application Design, Units Planning, and Units Generation all marked EXECUTE (new components/methods need definition; this is a genuine multi-unit, multi-module change). All four per-unit Construction design stages (Functional Design, NFR Requirements, NFR Design, Infrastructure Design) marked EXECUTE at the feature level, with an explicit note that some may turn out to be minimal/skippable for a pure hosting-extraction unit once Units Generation defines the actual unit boundaries. Code Generation and Build and Test marked EXECUTE (always). All three Operations-phase stages marked EXECUTE, consistent with D-7/D-13/D-15. Created `inception/plans/execution-plan.md` with the full analysis, a Mermaid component-relationship diagram, a Mermaid workflow-visualization flowchart (colored per the standard styling: green = completed/always-execute, orange dashed = conditional-execute), and the phase-by-phase execute list.

Read `SlpModularCms.Api/Program.cs` in full and confirmed it contains no project-specific branches outside the bootstrap lines, meaning FR-3's extraction can go as far as a single shared entrypoint if desired. Read `SlpModularCms.Modules.Master`'s file layout as the existing module-pattern reference (Controllers/Services/Repositories/Data/Models). Created `inception/plans/application-design-plan.md` with a 6-step checklist and 5 embedded questions: how far the `CmsHost` extraction should go (single `RunAsync` entrypoint vs. two granular configure methods), whether to mirror Master's Repository+Service layering or skip the Repository given the module's own simple-CRUD characterization (from the PBT opt-out), public/admin controller split, new-offering ID strategy (GUID vs. admin-provided slug), and delete semantics (hard vs. soft delete, tying into the SECURITY-13 open item flagged in requirements.md)."

Asked 3 genuine questions: the unit boundary itself (2 units: Foundation + Offerings vs. 1 combined vs. 3 split further), naming for those units, and whether it's acceptable for the Foundation unit to carry zero directly-mapped user stories in the story-map (since all 12 stories belong to Offerings; Foundation only carries FR-1/FR-2/FR-3)."

Skipped it and logged the rationale rather than presenting a full completion message for a stage that didn't run. Proceeded directly to NFR Requirements: created `construction/plans/slpsoftware-client-setup-nfr-requirements-plan.md` with a 2-step checklist and 2 embedded questions (regression-test rigor for proving CmsHost reproduces Api's exact current pipeline behavior; whether CmsHost's methods should take a configuration-options parameter now for future per-project divergence or stay parameterless per YAGNI). Carried forward two points without asking: no new attack surface is introduced by this unit (stated directly, since Security Compliance for this unit reduces to 'does the regression testing from Q1 actually prove nothing changed' rather than a separate open question), and database separation between Api and Api.SlpSoftware follows the existing per-project appsettings pattern already used for Api/Api.Slave (no change, no question needed)."

+
+**AI Response**: "Q1's answer was a checkable condition, not a vague answer — investigated instead of asking a follow-up. Searched the whole solution for `WebApplicationFactory` usage: zero results. Checked `SlpModularCms.Core.Tests/Hosting/*`: existing tests (`SecurityHeadersOptionsValidationTests`, `PathPolicyResolverTests`, `DeployedConfigurationTests`, etc.) are unit-level, testing option classes and resolvers in isolation — none spin up the actual HTTP pipeline. There is also no dedicated `Api.Tests` project. Conclusion: existing coverage does NOT verify pipeline-level behavior (headers present on real responses, health endpoint reachable, SPA fallback resolving, rate limiter engaging) at all, so per the user's own decision rule this resolves to **B** — new integration tests are needed as permanent regression guards. For Q2, before designing `CmsHostOptions`, checked `DataProtectionExtensions.cs` and found `ApplicationDiscriminator` is a deliberate hardcoded constant (`\"SlpModularCms\"`) with an explicit code comment stating it must NOT become configurable, since a mismatched discriminator between instances silently breaks Data Protection key decryption. This directly constrains the new options object: `CmsHostOptions` must not expose anything that touches the Data Protection application name. Proceeding to generate `nfr-requirements.md` and `tech-stack-decisions.md` for Unit 1 incorporating both findings."

Also recognized that darkening the node FILL colors (my prior fix) was counterproductive for black text contrast — darker fill reduces contrast with black text, it doesn't increase it. Reverted fills to lighter pastel shades (closer to the original palette) while keeping color:#000000 and font-weight:bold on the text, and added an explicit `linkStyle default stroke:#666666,stroke-width:2px` to both diagrams so arrows have a fixed, visible mid-gray regardless of theme."

Key finding: `StaticContentExtensions.cs` (and its embedded `WebsitePlaceholder.html`) currently live inside the `Api` project itself, not `Core` — since `CmsHost` must live in `Core` and `Core` cannot depend on `Api`, this file has to move to `Core` first, as its own explicit step, before `CmsHost` can call it. Also confirmed `appsettings.local.json` is gitignored and untracked, so the plan does not create one for the new project. Created a 13-step plan covering: moving StaticContentExtensions to Core, adding CmsHostOptions and CmsHost, rewriting Api/Program.cs, scaffolding the new Api.SlpSoftware project (csproj/Program.cs/appsettings, deliberately without Program.Coverage.cs since Q1=C scoped pipeline tests to Api only), .sln updates for both new projects (Api.SlpSoftware under Clients, Api.Tests directly under Tests mirroring Core.Tests's placement), the new Api.Tests project with WebApplicationFactory-based pipeline regression tests, a markdown code summary, explicit N/A steps for API/Repository Layer and DB migrations (this unit has neither), a README update, an explicit N/A for deployment artifacts (Operations-phase scope), and the mandatory Step 13.5 build/test verification."

Step 1: moved StaticContentExtensions.cs + WebsitePlaceholder.html from Api/Extensions/ into Core/Hosting/, updated namespace and embedded-resource name, updated both .csproj files, deleted the now-empty Extensions directory. Steps 2-3: created CmsHostOptions.cs (empty) and CmsHost.cs (ConfigureServices/ConfigurePipeline) in Core/Hosting/, faithfully reproducing Api/Program.cs's exact composition and ordering. Step 4: rewrote Api/Program.cs to the thin form. Step 5: created the full SlpModularCms.Api.SlpSoftware project (csproj, Program.cs, appsettings.json, appsettings.Development.json with its own isolated 'SlpModularCmsSlpSoftwareDev' local database per Infrastructure Design Q1=B, plus a launchSettings.json on distinct ports 5286/7222 so it can run alongside Api locally — a mechanical necessity not explicitly in the plan, added without a separate approval round). Step 6: added both new projects to SlpModularCms.sln (Api.SlpSoftware under Clients, Api.Tests directly under Tests) with fresh GUIDs. Step 7: created SlpModularCms.Api.Tests with PipelineTests.cs (4 tests). Step 8: wrote the code summary. Steps 9-10, 12: confirmed N/A as planned. Step 11: updated README.md (Projectstructuur section, a note on CmsHost, and a launch note for Api.SlpSoftware's own local database). Step 13.5 (build/test verification): initial build failed twice — (1) Core.csproj was missing the Scalar.AspNetCore package reference MapScalarApiReference() now needs there, (2) CmsHost.cs and the moved StaticContentExtensions.cs were missing explicit `using Microsoft.Extensions.Hosting`/`Microsoft.Extensions.DependencyInjection` since Core is a plain Sdk project without ASP.NET Core's implicit usings that Api (Sdk.Web) had. Fixed both directly, per Step 13.5's 'diagnose and fix it directly' rule — no separate approval round needed. Local MariaDB was required for the new pipeline tests (real startup migration) and was not running; started the existing podman machine and the existing 'mariadb' container (both were stopped, not newly created) and left them running for continued local development. Final result: build succeeded, SlpModularCms.Core.Tests 196/196 passed (no regression), new SlpModularCms.Api.Tests 4/4 passed, correctly asserting HSTS's Development-only absence rather than assuming it should always be present."

+**User Input**: "is er voor de CMS-frontend ook een pnpm script toegevoegd voor slpsoftware? net zoals pnpm dev:slave maar dan `pnpm dev:slpsoftware`?"

+**AI Response**: "Investigated before answering: frontend/.env.example documents that the existing 'slave' dev flow uses `VITE_API_BASE_URL=https://localhost:7222`, and `SlpModularCms.Api.Slave/Properties/launchSettings.json` confirms 7222 is that project's actual HTTPS port. This exposed a real bug from Code Generation: `Api.SlpSoftware`'s own launchSettings.json had been given 7222 as well — a genuine port collision, not yet noticed since nothing had exercised both projects together. Fixed by moving `Api.SlpSoftware` to port 7223 (`launchSettings.json`, and `appsettings.Development.json`'s self-referential `MasterModule:MasterUrl`, and the README note, all updated to match). No pnpm script existed yet for SlpSoftware — added `dev:slpsoftware` (`vite --mode slpsoftware --port 5175`) to `frontend/package.json`, mirroring `dev:slave` exactly, and documented the corresponding `.env.slpsoftware.local` pattern in `frontend/.env.example` (pointing at the now-corrected `https://localhost:7223`). Did not extend `dev:all` (master+slave concurrently) to include slpsoftware, since that wasn't asked and changing an established script's behavior deserves an explicit request first."

+
+**Timestamp**: 2026-08-02T11:05:00Z
+
+**User Input**: "als ik de Slp Softweare cms start dan krijg ik geen setup pagina. Dat zou wel moeten gezien het een nieuwe CMS is. Ik zie ook in de titel nog steeds staan SlpModularCms (Master) staan, dat mag veranderen naar CMS - Slp Software. Ook bij de Inlog-pagina zie ik staan \"Log in op je SlpModularCms-account\", maar het zou een SLP Software account moeten zijn. Ik weet dat dat functioneel wel wat toevoegt, maar je moet het als gebruiker vanuit de context van de klant zien en niet SlpModularCms" — followed by two clarifying-question rounds.
+
+**AI Response**: "Investigated via a research subagent (no code changes) rather than guessing. Finding 1 (title shows '(Master)'): not a bug — `VITE_APP_TITLE` comes from whichever `.env.*.local` file is active; the user was running default `pnpm dev` (loads `.env.local`) instead of `pnpm dev:slpsoftware` (needs a `.env.slpsoftware.local` the user hadn't created yet). Finding 2 (hardcoded 'SlpModularCms' text): centralized in exactly 2 i18n keys (`login.subtitle`, `common.appName`) x 2 locales, plus `index.html`'s `<title>` and a `config.ts` fallback literal. Finding 3 (no setup page): root-caused precisely — `SlpModularCms.Api.SlpSoftware/appsettings.local.json` (gitignored, pre-existing on this machine from earlier manual testing, predates this feature) overrides `appsettings.Development.json`'s connection string and points at a database that already has a user row, so `SetupService.IsSystemInitializedAsync()` (`Users.AnyAsync()`) correctly reports 'already initialized' — not a setup-logic bug. Asked the user how they want branding made configurable (backend-config vs. frontend build-time env var vs. defer) given the admin frontend is one shared build deployed to every Client project; the user's answer went further than any of the three options — they want a genuine CMS-managed 'Site Settings' capability (brand/site name editable by the CMS Administrator via an admin settings screen, database-backed, not just static config), with the harder multi-tenant/per-customer version explicitly deferred to later. Asked a second scoping question — new separate feature vs. a third unit in this feature — since this is domain-unrelated to both existing units and touches shared Core/Identity plus the unauthenticated login page. User chose: new, separate feature, started later. Saved as a project memory (`project_site_settings_future_feature.md`) so this doesn't get lost. Not implementing anything for this in the current feature."

Nu kan ik dev:slpsoftware doen, maar hij pakt 1 van de bestaande .env-bestanden" → clarified as meaning production builds specifically → "regel dan in ieder geval het lokale bestand voor SlpSoftware"
+
+**AI Response**: "Checked `.gitea/workflows/continuous_integration.yaml` directly: production/test builds never use `.env` files at all — Gitea Actions injects `VITE_*` values as real environment variables straight into the `pnpm build` step (`publish-test`/`publish-production` jobs), already exactly the 'per-deployment build-time config' mechanism the user was asking for. Explained this is Operations-phase scope (D-7/D-15, once Api.SlpSoftware gets its own deploy job with its own Gitea variables) and that committing per-customer `.env` files would actually regress against this existing, correct pattern (risk of committed secrets, redundant with variables that already exist). Not implementing anything for production builds. For the immediate, smaller ask, created `frontend/.env.slpsoftware.local` (2 lines, mirroring the existing `.env.slave.local` exactly: `VITE_API_BASE_URL=https://localhost:7223`, `VITE_APP_TITLE=SlpModularCms (SlpSoftware)`) — confirmed git-ignored via `git status --porcelain` (no output, matches the `*.local` pattern). `pnpm dev:slpsoftware` now resolves correctly."

+## Bug Fix: CORS Blocked the Setup-Status Check
+
+**Timestamp**: 2026-08-02T11:25:00Z
+
+**User Input**: "Waarom krijg ik geen setup voor SlpSoftware?"
+
+**AI Response**: "This time verified directly against the database instead of repeating the earlier (subagent-sourced) hypothesis: queried the local MariaDB via `podman exec` and found the `SlpSoftware` database (the one `Api.SlpSoftware/appsettings.local.json` — created by the user, not by this session — actually points at) has 0 rows in `Users`. That disproves the earlier 'pre-existing user blocks setup' explanation. Read `frontend/src/router.tsx`'s `InitGuard` logic and found the real cause: on a failed `/api/v1/Setup/status` fetch (e.g. a CORS rejection), the code catches the error and sets `status = { initialized: true }` — fails toward showing the login page, not setup. `Api.SlpSoftware/appsettings.Development.json`'s `Cors:AllowedOrigins` still listed `localhost:5173` (copied verbatim from `Api`'s own file during Code Generation), but `pnpm dev:slpsoftware` serves the frontend on port 5175 — a genuine CORS mismatch, causing exactly this fail-open-to-login behavior. Fixed `Cors:AllowedOrigins` to `localhost:5175`, with a comment explaining why 5173 was wrong for this project."

+## Pre-Existing Bug Fix: GlobalExceptionHandler Logged Expected 401s as Unhandled Errors
+
+**Timestamp**: 2026-08-02T11:35:00Z
+
+**User Input**: Pasted a `fail`-level console log for `UnauthorizedException: Ongeldig refresh token.` on `POST /api/v1/auth/refresh`, asking whether that's expected.
+
+**AI Response**: "Read `GlobalExceptionHandler.cs` and `GlobalExceptionHandlerTests.cs` directly. Confirmed this is pre-existing behavior, not introduced by this feature — I never touched `GlobalExceptionHandler`, `AuthService`, or `AuthController` during the Unit 1 extraction. The handler unconditionally called `_logger.LogError(...)` for every exception before even mapping it to a status code, so a routine, expected `UnauthorizedException` (missing/invalid refresh token on a fresh session — exactly what a brand-new SlpSoftware instance produces) was logged identically to a genuine unhandled 500, indistinguishable in the console or in Sentry. Fixed by reordering so `MapException` runs first, then logging at `LogError` only for statuses >= 500 (genuinely unexpected) and `LogWarning` for everything else (routine, mapped exceptions like 401). Verified no existing test asserts log level (only status code and response body), so nothing broke; reran the full suite — 196 Core.Tests + 4 Api.Tests, all green. Small, contained, low-risk fix in a file already open for investigation — applied directly per this session's 'fix small things found in passing' convention, since it's shared code affecting every Client project equally (Api, Api.Slave, Api.SlpSoftware), not specific to this feature's scope."

+**Context**: Drive-by fix to a pre-existing, unrelated defect discovered while testing this feature's output. Not a `slpsoftware-api` functional requirement. Returning to the Unit 1 Code Generation approval gate.

+**Timestamp**: 2026-08-02T11:40:00Z
+
+**User Input**: "Kan je de user uit SlpSoftware halen zodat ik het kan testen?"
+
+**AI Response**: "Checked `SetupService.CreateInitialOwnerAsync` first to confirm it's safe to leave `Roles` intact (it checks `RoleExistsAsync` before creating each role, so re-running setup against existing roles is a no-op for those, not an error). Deleted rows from the local `SlpSoftware` MariaDB database only (the one in the user's own `appsettings.local.json`): `RefreshTokens` (1), `UserRoles` (1), `Users` (1), in that FK-safe order. Verified all three are now 0. `Roles`/`RoleClaims` and all other tables left untouched."

+# Code Generation Plan — Unit: SlpSoftware Client Setup
+
+## Unit Context
+
+**Stories implemented**: None directly (unit-of-work-story-map.md — this unit is a purely technical enabling unit).
+**Functional requirements implemented**: FR-1, FR-2, FR-3.
+**Dependencies**: None on other units (this unit is the dependency Unit 2 "Offerings" needs).
+**Expected interfaces produced**: `SlpModularCms.Core.Hosting.CmsHost` (`ConfigureServices`/`ConfigurePipeline`), consumed by both Client projects' `Program.cs`.
+**Database entities owned**: None.
+**Workspace root**: `K:\Development\Projects\SlpModularCms` (brownfield — modify/move existing files where noted, never duplicate).
+
+## Investigation Finding That Shapes This Plan
+
+Reading `SlpModularCms.Api/Program.cs` and `SlpModularCms.Api/Extensions/StaticContentExtensions.cs` directly (not assumed) revealed that `UseCmsStaticContent()`/`MapCmsSpaFallbacks()` — needed by `CmsHost.ConfigurePipeline` — currently live in the **`Api` project itself**, not in `Core`. Since `Core` cannot depend on `Api` (wrong dependency direction — `Api` depends on `Core`, never the reverse), this file (and its embedded `WebsitePlaceholder.html` resource) must move into `Core` **before** `CmsHost` can call it. This is Step 1 below, not an afterthought.
+
+---
+
+## Steps
+
+### Step 1 — Move Static Content Hosting into Core (prerequisite for CmsHost)
+- [x] Move `src/SlpModularCms.Api/Extensions/StaticContentExtensions.cs` → `src/SlpModularCms.Core/Hosting/StaticContentExtensions.cs`; change namespace `SlpModularCms.Api.Extensions` → `SlpModularCms.Core.Hosting`; update `PlaceholderResourceName` from `"SlpModularCms.Api.Extensions.WebsitePlaceholder.html"` to `"SlpModularCms.Core.Hosting.WebsitePlaceholder.html"`
+- [x] Move `src/SlpModularCms.Api/Extensions/WebsitePlaceholder.html` → `src/SlpModularCms.Core/Hosting/WebsitePlaceholder.html`
+- [x] `SlpModularCms.Core.csproj`: add `<EmbeddedResource Include="Hosting\WebsitePlaceholder.html" />`
+- [x] `SlpModularCms.Api.csproj`: remove the now-obsolete `<EmbeddedResource Include="Extensions\WebsitePlaceholder.html" />` item group and its explanatory comment (the file no longer lives there)
+- [x] Delete the now-empty `src/SlpModularCms.Api/Extensions/` directory if nothing else remains in it
+
+### Step 2 — `CmsHostOptions` (Business Logic Generation — Core)
+- [x] Create `src/SlpModularCms.Core/Hosting/CmsHostOptions.cs`: an intentionally empty class (NFR Design Pattern 2 / Q2 = B) — a pure extension point, no properties yet
+
+### Step 3 — `CmsHost` (Business Logic Generation — Core)
+- [x] Create `src/SlpModularCms.Core/Hosting/CmsHost.cs` with:
+  - `public static ModuleOrchestrator ConfigureServices(WebApplicationBuilder builder, CmsHostOptions options)` — reproduces `Api/Program.cs` lines for: `appsettings.local.json` loading stays in each project's own `Program.cs` (NOT moved here — application-design.md component-methods.md is explicit that bootstrap lines stay per-project); logging (`AddCmsLogging`), Sentry (`UseCmsSentry`), `ModuleOrchestrator` construction + `DiscoverModules()`, `AddCoreInfrastructure`, `AddCmsCors`, `AddCmsRateLimiting`, `AddCmsHealthChecks`, `AddCmsSecurityHeaders`, `AddCmsObservability`, `AddCmsDataProtection` (before module services — order preserved exactly), `RegisterModuleServices`, `AddSingleton(orchestrator)`, `AddControllers` with `ApiPrefixConvention("api/v1")` + `JsonStringEnumConverter`. Returns the orchestrator.
+  - `public static void ConfigurePipeline(WebApplication app, ModuleOrchestrator orchestrator, CmsHostOptions options)` — reproduces: `MigrateCoreDatabase`, `UseExceptionHandler`, `UseCmsSecurityHeaders`, `UseRateLimiter`, Development-only `MapOpenApi`/`MapScalarApiReference`, `UseHttpsRedirection`, `UseCmsStaticContent`, `UseCors`, `orchestrator.UseModules(app)`, `UseAuthentication`/`UseAuthorization`, `MapControllers`, `MapCmsHealthChecks`, `MapSentryTunnel`, `MapCmsSpaFallbacks` — same order as today's `Program.cs`, since that order encodes real constraints documented in its comments
+- [x] Both methods accept `CmsHostOptions` per NFR-CS-02, even though it currently has no properties to read
+
+### Step 4 — Repoint `SlpModularCms.Api/Program.cs` (Modify In-Place)
+- [x] Rewrite `src/SlpModularCms.Api/Program.cs` to the thin form: create builder, load `appsettings.local.json`, `var orchestrator = CmsHost.ConfigureServices(builder, new CmsHostOptions());`, `var app = builder.Build();`, `CmsHost.ConfigurePipeline(app, orchestrator, new CmsHostOptions());`, `app.Run();`
+- [x] No behavior change — verified by Step 7's regression tests
+
+### Step 5 — New Client Project: `SlpModularCms.Api.SlpSoftware` (Project Structure Setup)
+- [x] Create `src/SlpModularCms.Api.SlpSoftware/SlpModularCms.Api.SlpSoftware.csproj` — mirrors `SlpModularCms.Api.csproj` (SDK, `TargetFramework`, `Nullable`, `ImplicitUsings`, same package references: `Asp.Versioning.Mvc`, `Microsoft.AspNetCore.Authentication.JwtBearer`, `Microsoft.AspNetCore.OpenApi`, `Microsoft.EntityFrameworkCore.Design`, `Scalar.AspNetCore`), **without** the `WebsitePlaceholder.html` embedded resource (that now lives in `Core`, shared) and **without** a `Modules.Offerings` reference (added later by Unit 2, per unit-of-work.md)
+  - `ProjectReference`: `SlpModularCms.Core`, `SlpModularCms.Modules.Availability`, `SlpModularCms.Modules.Identity`, `SlpModularCms.Modules.Master` (FR-2)
+- [x] Create `src/SlpModularCms.Api.SlpSoftware/Program.cs` — same thin shape as Step 4's rewritten `Api/Program.cs`
+- [x] Create `src/SlpModularCms.Api.SlpSoftware/appsettings.json` — mirrors `Api`'s structure/keys (connection string placeholder, JWT settings, Availability, MasterModule, MasterPolling, Cors, RateLimiting, SecurityHeaders, Observability sections)
+- [x] Create `src/SlpModularCms.Api.SlpSoftware/appsettings.Development.json` — mirrors `Api`'s Development file, but with its **own isolated local dev database name** (Infrastructure Design Q1 = B), e.g. `Database=SlpModularCmsSlpSoftwareDev`
+- [x] **Not creating** `appsettings.local.json` — it's git-ignored (verified: listed in `.gitignore`, not tracked in git) and personal per-developer; the developer creates their own copy locally if needed, same as for `Api`
+- [x] **Not creating** `Program.Coverage.cs` for this project in this unit — Infrastructure/NFR Design (Q1 = C) scoped the new pipeline regression tests to `Api` only, so there is no test target requiring `Program` to be a public partial class here yet; add it in a future unit/feature if `Api.SlpSoftware`-specific pipeline tests are ever introduced
+
+### Step 6 — Solution File Updates (`SlpModularCms.sln`)
+- [x] Add `SlpModularCms.Api.SlpSoftware` project entry, nested under the existing (currently empty) `Clients` solution folder (`{D72703E6-B021-4360-B1EE-0E99999B5899}`)
+- [x] Add `SlpModularCms.Api.Tests` project entry (Step 7), nested directly under `Tests` (`{2F43D186-C7D5-4AB1-B821-4D595CA2ECB3}`) — mirroring how `SlpModularCms.Core.Tests` is nested directly under `Tests`, not under `Tests/Modules`
+- [x] Add both new projects' GUIDs to `ProjectConfigurationPlatforms` (Debug/Release × Any CPU/x64/x86, matching the existing pattern for every other project)
+- [x] Add both new projects' GUIDs to `NestedProjects`
+
+### Step 7 — Pipeline Regression Tests (Business Logic Unit Testing, NFR-CS-01)
+- [x] Create `src/SlpModularCms.Api.Tests/SlpModularCms.Api.Tests.csproj` — same SDK-style shape as `SlpModularCms.Core.Tests.csproj` (xunit, FluentAssertions, `Microsoft.NET.Test.Sdk`, `coverlet.collector`), plus `Microsoft.AspNetCore.Mvc.Testing` (provides `WebApplicationFactory<TEntryPoint>`); `ProjectReference` to `SlpModularCms.Api.csproj` (its `Program.Coverage.cs` already makes `Program` a public partial class, so no further change needed there)
+- [x] Create `src/SlpModularCms.Api.Tests/PipelineTests.cs` using `WebApplicationFactory<Program>`, asserting (NFR-CS-01 / NFR Design Pattern 1):
+  - Required security headers (CSP, HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy) present on a representative response
+  - `/health` returns a successful response
+  - A non-file `/admin/{path}` route resolves to the admin SPA's `index.html` fallback (or, absent a built SPA in the test environment, at minimum does not 404 as a missing-file/static-asset request would)
+  - A burst of requests against a rate-limited route eventually receives `429 Too Many Requests`
+
+### Step 8 — Business Logic Summary
+- [x] Create `aidlc-docs/features/slpsoftware-api/construction/slpsoftware-client-setup/code/summary.md` (markdown only) summarizing: files moved (Step 1), `CmsHost`/`CmsHostOptions` added, `Api/Program.cs` rewritten, `Api.SlpSoftware` created, solution file changes, tests added
+
+### Step 9 — API Layer / Repository Layer Generation
+- [x] **N/A** — this unit introduces no new HTTP endpoints or persisted entities (FR-1/FR-2/FR-3 are pure composition/project-scaffolding); these categories apply to Unit 2 "Offerings" instead
+
+### Step 10 — Database Migration Scripts
+- [x] **N/A** — no new data model in this unit
+
+### Step 11 — Documentation Generation
+- [x] Update root `README.md`: add `SlpModularCms.Api.SlpSoftware` to the project-structure description alongside `SlpModularCms.Api`/`SlpModularCms.Api.Slave`, and add a short note under the existing architecture/hosting section explaining `CmsHost` as the shared composition point both Client projects call, plus a one-line note that `Api.SlpSoftware` uses its own local dev database (Infrastructure Design Q1 = B)
+
+### Step 12 — Deployment Artifacts Generation
+- [x] **N/A for this Construction stage** — per Infrastructure Design, no `.gitea/workflows/*.yaml` or Gitea Actions variable changes happen here; the CI/CD retarget is explicitly Operations-phase work (D-7/D-15)
+
+### Step 13 — Build and Test Verification (automatic, Step 13.5 of the workflow)
+- [x] Build the full solution (or at minimum `Api`, `Api.SlpSoftware`, `Core`, `Api.Tests`) and confirm it compiles
+- [x] Run `SlpModularCms.Api.Tests` (new) and confirm all pipeline regression tests pass against `Api`
+- [x] Run `SlpModularCms.Core.Tests` (existing) and confirm nothing regressed from the Step 1 file move
+- [x] Fix and retry on any failure; only surface to the user if a fix requires a decision only they can make
+
+---
+
+**Scope reminder**: this plan implements Unit 1 only. Unit 2 "Offerings" (all 12 user stories) is a separate Code Generation pass, after this unit is approved and its own Build and Test step is green.

+# Infrastructure Design Plan — Unit: SlpSoftware Client Setup
+
+Voordat ik vragen stelde, heb ik `aidlc-docs/features/gitea-deployment-workflow/operations/deployment/deployment-instructions.md` (de bestaande, gedetailleerde deploy-documentatie van de feature die de huidige pipeline bezit) volledig gelezen. Dat geeft keihard bewijs voor bijna elke categorie hieronder — vandaar dat er maar één echte vraag overblijft.
+
+## Al opgelost via bestaand bewijs (geen vraag nodig)
+
+- **Deployment Environment / Compute**: één Raspberry Pi ("pi-main"), test en productie gescheiden per directory/systemd-unit/poort (5100/5101). Een aparte proxy-Pi regelt TLS-terminatie. Dit verandert niet door deze feature — D-15 is een **cutover**, geen nieuwe, aparte deploy-slot. Zodra de Operations-fase de pipeline omzet, draait `Api.SlpSoftware` **op precies dezelfde plek** als `Api` nu draait: zelfde Pi, zelfde systemd-unitnamen (`slpsoftware-test.service`/`slpsoftware-production.service`), zelfde poorten, zelfde domeinen. Het enige wat verandert is de ExecStart-regel (`SlpModularCms.Api.dll` → `SlpModularCms.Api.SlpSoftware.dll`) en het CI-publish-artefact — en dat is expliciet Operations-werk (D-7), niet iets wat deze Construction-stage of deze unit's Code Generation al hoeft aan te passen.
+- **Networking**: geen nginx-wijziging nodig (al vastgelegd als D-6/NFR-1) — de bestaande proxy-Pi-configuratie blijft ongewijzigd, hij proxied gewoon naar dezelfde poort, ongeacht welke `.dll` daar luistert.
+- **Storage (productie/test)**: zelfde MariaDB-instantie op pi-main, zelfde databasenamen (`SlpSoftwareTest`/`SlpSoftwareProduction`) — logisch gevolg van "cutover, geen nieuwe aparte app".
+- **Monitoring**: zelfde Sentry-project/DSN, onderscheiden via de bestaande `Observability__Environment`-tag — geen wijziging nodig.
+- **Shared Infrastructure/multi-tenancy**: N/A — single-tenant deployment, geen wijziging.
+- **Geen wijzigingen aan `.gitea/workflows/*.yaml` of Gitea Actions-variabelen in deze stage** — dat is expliciet Operations-fase-werk (D-7/D-15). Deze stage documenteert alleen de doelvorm, zodat Code Generation niets bouwt wat daar niet in past.
+
+## Uitvoeringschecklist
+
+- [x] Stap A — `infrastructure-design.md`: bovenstaande bevindingen + antwoord op Vraag 1 vastleggen
+- [x] Stap B — `deployment-architecture.md`: doelarchitectuur voor `Api.SlpSoftware` na de toekomstige cutover (referentie, geen wijziging nu)
+

+
+## Vragen
+
+### Vraag 1 — Lokale ontwikkeldatabase voor `Api.SlpSoftware`
+Voor productie/test is de databasekeuze al duidelijk (hierboven). Voor **lokale ontwikkeling** (jouw eigen machine) is dat nog niet vastgelegd: moet `Api.SlpSoftware` lokaal dezelfde database gebruiken als `Api` vandaag, of een eigen, aparte lokale database?
+
+A) Dezelfde lokale database als `Api` — handig als je makkelijk wilt wisselen tussen beide projecten met dezelfde testdata; risico op onderlinge beïnvloeding tijdens ontwikkeling van de Offerings-module (Unit 2)
+B) Eigen, aparte lokale database voor `Api.SlpSoftware` — geïsoleerde ontwikkelomgeving, geen kans dat het testen van de Offerings-module `Api`'s lokale data raakt; wel een aparte lokale database aanmaken

+### Vraag 1 — Tegen welk(e) project(en) draaien de nieuwe pipeline-tests?
+NFR-CS-01 vereist nieuwe `WebApplicationFactory`-gebaseerde tests die het pipeline-gedrag verifiëren. Ze kunnen tegen `Api`, tegen `Api.SlpSoftware`, of tegen beide draaien.
+
+A) Tegen beide Client-projecten — één gedeelde/geparametriseerde testsuite die tegen zowel `Api` als `Api.SlpSoftware` draait; sterkste garantie dat `CmsHost` zich op beide identiek gedraagt, iets meer testtijd
+B) Alleen tegen `Api.SlpSoftware` — het project waar het écht om gaat (toekomstige productie-host); `Api` blijft ongetest op pipeline-niveau maar heeft z'n bestaande (unit-niveau) testsuite nog
+C) Alleen tegen `Api` — bestaat al, sneller op te zetten; `Api.SlpSoftware` erft het vertrouwen via de gedeelde `CmsHost`-code

+
+### Vraag 2 — Inhoud van `CmsHostOptions`
+Tech-stack-decisions.md liet de exacte vorm van `CmsHostOptions` open. Voor het NFR-ontwerp: moet de klasse nu al één concreet, direct nuttig veld krijgen, of blijft het een lege plaatshouder?
+
+A) Eén concreet veld nu: bijv. `HostLabel`/`ApplicationName` (string) — gebruikt voor observability-tagging (logs/Sentry), zodat je straks in gedeelde logging kunt onderscheiden of een entry van `Api` of `Api.SlpSoftware` komt. Direct nuttig, geen giswerk over toekomstige velden.

+
+**Waarom Functional Design is overgeslagen voor deze unit**: geen nieuw datamodel, geen nieuwe business rules — dit is een pure hosting-compositie-extractie (FR-1/FR-2/FR-3), zonder domeinlogica om te ontwerpen. Rechtstreeks door naar NFR Requirements.
+
+**Al vastgelegd, hier niet opnieuw bevraagd**:
+- **Security**: deze unit introduceert geen nieuw aanvalsoppervlak (geen nieuwe module, geen nieuwe business logic) — het enige vereiste is dat de bestaande Security Baseline-regels (SECURITY-03/04/09/10/14/15) na de extractie **exact** hetzelfde gedrag opleveren als vandaag. Zie Vraag 1 hieronder voor hoe dat geverifieerd wordt.
+- **Database-scheiding**: `Api` en `Api.SlpSoftware` gebruiken elk hun eigen `appsettings.json`/`appsettings.local.json` (bestaand `dotnet-appsettings`-patroon, ook al toegepast tussen `Api` en `Api.Slave`) — dus per omgeving een eigen connection string. Geen wijziging t.o.v. vandaag, geen vraag nodig.

+## Vragen
+
+### Vraag 1 — Regressietest-strengheid voor de `CmsHost`-extractie
+`Api/Program.cs` bevat vandaag gedrag dat niet mag veranderen: security headers, rate limiting, health checks, static content + SPA-fallback, Sentry-tunnel. Hoe streng moet geverifieerd worden dat `CmsHost` dat gedrag exact reproduceert?
+
+A) Vertrouwen op `Api`'s bestaande testsuite die ongewijzigd groen blijft — voldoende signaal, geen nieuwe tests specifiek voor deze extractie
+B) Nieuwe integratietests toevoegen die specifiek het pipeline-gedrag assert (headerwaarden aanwezig, health-endpoint bereikbaar, SPA-fallback lost op) — blijvende regressiebewaking voor beide Client-projecten, ook na deze feature

+[Answer]: A, als dit voldoende dekking geeft, anders B
+
+### Vraag 2 — Uitbreidbaarheid van `CmsHost`
+`CmsHost.ConfigureServices`/`ConfigurePipeline` (application-design/component-methods.md) hebben vandaag geen parameters buiten `WebApplicationBuilder`/`WebApplication` — beide Client-projecten roepen ze identiek aan.
+
+Moet er nu al ruimte komen voor toekomstige verschillen tussen projecten (bijv. een `CmsHostOptions`-object), of pas toevoegen zodra er een echte reden voor is?

+Prompted by a user question about a frontend `pnpm dev:slpsoftware` script, investigation surfaced a real bug: `Api.SlpSoftware`'s `launchSettings.json` had been assigned HTTPS port **7222**, which is already `SlpModularCms.Api.Slave`'s port (confirmed via `frontend/.env.example` and `Api.Slave/Properties/launchSettings.json`). Fixed:
+- `src/SlpModularCms.Api.SlpSoftware/Properties/launchSettings.json` — HTTPS port 7222 → **7223** (HTTP 5286 unchanged, already free)
+- `src/SlpModularCms.Api.SlpSoftware/appsettings.Development.json` — `MasterModule:MasterUrl` updated to match (`https://localhost:7223`)
+- `README.md` — corrected port note, with an explicit call-out of the 7222 collision reason
+
+Added (frontend, not part of the original per-unit plan, but a direct, symmetrical follow-up to the port fix):
+- `frontend/package.json` — `dev:slpsoftware` script (`vite --mode slpsoftware --port 5175`), mirroring `dev:slave`
+- `frontend/.env.example` — documented the `.env.slpsoftware.local` pattern (`VITE_API_BASE_URL=https://localhost:7223`, `VITE_APP_TITLE=SlpModularCms (SlpSoftware)`)
+
+## Post-Completion Fix: CORS Origin Mismatch Blocked the Setup Page
+
+`Api.SlpSoftware/appsettings.Development.json`'s `Cors:AllowedOrigins` had been copied from `Api`'s own file verbatim, listing `localhost:5173` — but `pnpm dev:slpsoftware` serves the frontend on port **5175**. The mismatch caused the frontend's `/api/v1/Setup/status` check to fail on CORS, and `router.tsx`'s `InitGuard` fails open toward the login page (not setup) on any fetch error — so the setup page never appeared, even against a genuinely empty database (verified directly via the local MariaDB, not assumed). Fixed: `Cors:AllowedOrigins` now lists `localhost:5175`.
+
+## Post-Completion Fix: GlobalExceptionHandler Logged Expected 401s as Errors
+
+Pre-existing bug, unrelated to this feature's own scope (not introduced by the `CmsHost` extraction) but surfaced by testing the new instance: `src/SlpModularCms.Core/Exceptions/GlobalExceptionHandler.cs` logged every exception at `LogError` before mapping it to a status code, so a routine `UnauthorizedException` (e.g. an invalid/missing refresh token — the normal state for a fresh, never-logged-in session) was indistinguishable from a genuine unhandled 500 in the console and in Sentry. Fixed: exceptions that map to a status below 500 now log at `LogWarning`; only genuinely unmapped exceptions (500) log at `LogError`. Affects every Client project equally (`Api`, `Api.Slave`, `Api.SlpSoftware`), not just this feature. No existing test asserted log level; full suite reran green (196 + 4).
+
+## Build and Test Verification (Step 13.5)
+
+Two real build fixes were needed and applied during this step (not deviations from the plan — the plan didn't anticipate these, since they only surface once the code actually compiles):
+1. `SlpModularCms.Core.csproj` was missing a `Scalar.AspNetCore` package reference — `CmsHost.ConfigurePipeline` calls `MapScalarApiReference()`, which moved into `Core` along with the rest of the pipeline composition but the package reference hadn't followed it. Added.
+2. `CmsHost.cs` and the moved `StaticContentExtensions.cs` were missing explicit `using Microsoft.Extensions.Hosting;` / `using Microsoft.Extensions.DependencyInjection;` — `Core` is an `Microsoft.NET.Sdk` project (not `Sdk.Web`), so it does not get ASP.NET Core's implicit usings the way `Api` (`Sdk.Web`) did. Added both.
+
+After both fixes:
+- **Build**: ✅ Success (full solution, all 13 projects)
+- **`SlpModularCms.Core.Tests`**: ✅ 196 passed, 0 failed — no regression from the Step 1 file move
+- **`SlpModularCms.Api.Tests`** (new): ✅ 4 passed, 0 failed — `/health` reachable, required security headers present on an HTML response (with HSTS's Development-only absence correctly asserted, not overlooked), `/admin` fallback 404s correctly with no build present, the `sentry-tunnel` rate limiter engages past its configured permit limit
+
+**Local environment note**: running the new tests required a local MariaDB (the same one `Api` itself needs to run, per the README). It was stopped; started it via `podman machine start` + `podman start mariadb` for this verification, and left both running afterward for continued local development (including Unit 2 "Offerings").

+# Infrastructure Design — Unit: SlpSoftware Client Setup
+
+## Production / Test Infrastructure — No Change Now, Documented Target for the Future Cutover
+
+Sourced directly from `aidlc-docs/features/gitea-deployment-workflow/operations/deployment/deployment-instructions.md` (the authoritative, existing deploy documentation, owned by that feature):
+
+| Aspect | Current (`Api`) | Target after D-15 cutover (`Api.SlpSoftware`) |
+|---|---|---|
+| Host | Single Raspberry Pi ("pi-main") | **Same Pi** — no new host |
+| TLS termination | Separate "proxy Pi", reverse-proxies to pi-main | **Unchanged** |
+| Process manager | `systemd --user`, units `slpsoftware-test.service` / `slpsoftware-production.service` | **Same unit names** — only the `ExecStart` line's `.dll` filename changes |
+| Ports | 5100 (test), 5101 (production) | **Unchanged** |
+| Database | MariaDB on pi-main, `SlpSoftwareTest` / `SlpSoftwareProduction` | **Unchanged** — same instance, same database names (this is a cutover of which binary runs, not a new environment) |
+| Monitoring | Shared Sentry project, distinguished by `Observability__Environment` | **Unchanged** |
+| Reverse proxy config | nginx on the proxy Pi, `proxy_pass` to pi-main's port | **Unchanged** — nginx doesn't know or care which `.dll` is listening (D-6/NFR-1) |
+
+**What actually changes at cutover time** (Operations phase, D-7/D-15 — explicitly **not** this Construction stage or this unit's Code Generation):
+- The systemd unit's `ExecStart` line: `SlpModularCms.Api.dll` → `SlpModularCms.Api.SlpSoftware.dll`
+- The CI/CD pipeline's publish/artifact step, to build and ship `Api.SlpSoftware` instead of `Api`
+
+**Why this matters for Code Generation (this unit, now)**: `SlpModularCms.Api.SlpSoftware` must be structurally deployable into this exact same shape without modification — same `wwwroot/web` symlink convention, same `/health` endpoint contract, same `ASPNETCORE_URLS=http://0.0.0.0:<port>` binding pattern, same environment-file-based configuration approach. This is already satisfied by design, since `Api.SlpSoftware` consumes the same `CmsHost` composition as `Api` (Unit 1's own FR-3) — there is nothing extra to build here, only something to avoid accidentally breaking.
+
+## No Changes to CI/CD or Gitea Actions Configuration in This Stage
+
+`.gitea/workflows/continuous_integration.yaml`, `deploy-scp.yaml`, and the Gitea Actions variables/secrets listed in deployment-instructions.md § 1.9 are **not** touched by this unit or this Construction phase. That retarget is explicitly Operations-phase scope (D-7, D-15) and belongs to a later stage of this feature, coordinated with the `gitea-deployment-workflow` feature that owns those files.
+
+## Local Development Database (Decision Q1 = B)
+
+`Api.SlpSoftware` uses its **own, isolated local development database**, separate from `Api`'s local dev database. Rationale: developing and testing the Offerings module (Unit 2) against `Api.SlpSoftware` should not risk touching or corrupting whatever local data `Api` already has, and vice versa.
+
+**Implication for Code Generation**: `Api.SlpSoftware`'s `appsettings.Development.json` gets its own `ConnectionStrings:DefaultConnection` pointing at a distinct local database name (e.g. a `SlpModularCmsSlpSoftwareDev`-style name — exact naming is a Code Generation Planning detail, not decided here), following the same `dotnet-appsettings` pattern already used by `Api`.

+
+**Type**: Test project / test fixture (new logical component, no runtime footprint in production).
+
+**Scope**: Targets `SlpModularCms.Api` only (Q1 = C). Exact host project (new `SlpModularCms.Api.Tests` vs. extending `SlpModularCms.Core.Tests`) is a Code Generation Planning decision — this stage fixes *what* it tests and *against which project*, not its exact file location.
+
+**Integration pattern**: `Microsoft.AspNetCore.Mvc.Testing`'s `WebApplicationFactory<TEntryPoint>`, using `Api`'s own `Program.cs` as the entry point (requires `Api`'s `Program.cs` to be accessible to the test project via the standard `InternalsVisibleTo`/top-level-statement partial-class pattern, if not already the case for other reasons).

+# NFR Design Patterns — Unit: SlpSoftware Client Setup
+
+## Pattern 1: Pipeline Regression Test, Scoped to `Api` (NFR-CS-01)
+
+**Decision** (Q1 = C): the new `WebApplicationFactory`-based integration tests target **`SlpModularCms.Api` only**. `SlpModularCms.Api.SlpSoftware` is not separately pipeline-tested in this unit — it inherits confidence transitively through the shared `CmsHost.ConfigureServices`/`ConfigurePipeline` code path that both projects call identically.
+
+**Pattern**: a single `WebApplicationFactory<TEntryPoint>`-based test fixture, pointed at `Api`, asserting on real HTTP responses:
+- Security headers present (CSP, HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy) — CSP presence and required directives only, not the exact Umami/Sentry exceptions (those are `Api`-specific configuration, unrelated to `CmsHost` correctness).
+- `/health` returns success.
+- A non-file `/admin/*` route resolves to the admin SPA's `index.html`.
+- A burst of requests against a rate-limited route eventually receives a `429`.
+
+**Accepted trade-off**: if a future change to `CmsHost` behaves differently under `Api.SlpSoftware`'s specific module composition (Offerings module present) than under `Api`'s, this test suite alone would not catch it. This is an accepted gap per the user's decision, not an oversight — full end-to-end coverage of `Api.SlpSoftware` itself is covered later by the feature-wide Build and Test phase once Unit 2 exists.
+
+## Pattern 2: `CmsHostOptions` as an Empty Extension Point (NFR-CS-02)
+
+**Decision** (Q2 = B): `CmsHostOptions` is introduced as a genuinely empty class (or, in C# terms, a class with zero properties, or `internal sealed record CmsHostOptions;` — exact syntax decided at Code Generation) — a placeholder in the method signature, not a placeholder-with-a-guess-field.
+
+**Pattern**: standard **Options Object** pattern, sized for its current job (nothing) rather than a speculative future job. Both `Api` and `Api.SlpSoftware` construct `new CmsHostOptions()` and pass it to `CmsHost.ConfigureServices(builder, options)` / `ConfigurePipeline(app, orchestrator, options)`. When a real per-project difference appears later, a property is added to this one class rather than changing either method's signature again.
+
+**Constraint carried forward** (from NFR-CS-02 / tech-stack-decisions.md): whatever is eventually added to `CmsHostOptions`, it must never affect `DataProtectionExtensions.ApplicationDiscriminator` — that stays the hardcoded `"SlpModularCms"` constant regardless.
+
+## Pattern 3: Security — Verification, Not New Design (NFR-CS-03)
+
+No new security pattern is introduced by this unit. The applicable pattern is "prove equivalence," fully covered by Pattern 1's regression tests. No additional logical components (WAF, extra middleware, etc.) are needed.

+# NFR Requirements — Unit: SlpSoftware Client Setup
+
+## NFR-CS-01 — Pipeline-Level Regression Test Coverage (Reliability / Testability)
+
+**Requirement**: The `CmsHost` extraction MUST be verified by new automated integration tests that exercise the actual HTTP pipeline, not unit tests of individual option classes.
+
+**Rationale**: Investigated the existing test suite before deciding (per the user's conditional answer to Q1 — "A if sufficient coverage exists, otherwise B"). Found:
+- Zero usages of `WebApplicationFactory` anywhere in the solution.
+- `SlpModularCms.Core.Tests/Hosting/*` tests (`SecurityHeadersOptionsValidationTests`, `PathPolicyResolverTests`, `DeployedConfigurationTests`, `SecurityEventsTests`) are unit-level — they test option/handler classes in isolation, not the composed pipeline.
+- No dedicated `Api.Tests` project exists.
+
+Existing coverage does **not** verify that security headers are actually present on a real response, that `/health` is reachable, that the SPA fallback resolves `/admin/*` routes, or that the rate limiter engages — all pipeline-composition behavior that `CmsHost` must reproduce exactly from today's `Api/Program.cs`. Per the decision rule in the user's own answer, this resolves to **Option B**.
+
+**Scope for Code Generation**: New `WebApplicationFactory`-based integration tests asserting, at minimum:
+- Required security headers (CSP, HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy) are present on a representative response.
+- `/health` returns a successful liveness response.
+- A non-file `/admin/*` route resolves to the admin SPA's `index.html` (SPA fallback).
+- The rate limiter is active (a burst of requests eventually receives a rate-limited response).
+
+These tests become a **permanent regression guard** for both `Api` and `Api.SlpSoftware`, not a one-time check discarded after this feature.
+
+## NFR-CS-02 — `CmsHost` Extensibility (Maintainability)
+
+**Requirement**: `CmsHost.ConfigureServices`/`ConfigurePipeline` accept a `CmsHostOptions` parameter, even though both current call sites (`Api`, `Api.SlpSoftware`) will pass equivalent values today.
+
+**Rationale**: Decision Q2 = B — proactive extensibility preferred over strict YAGNI for this specific extraction point, since it's the one place both current and future Client projects funnel through.
+
+**Constraint found during investigation**: `SlpModularCms.Core.Hosting.DataProtectionExtensions.ApplicationDiscriminator` is a deliberate hardcoded constant (`"SlpModularCms"`), with an explicit existing code comment stating it must never become configurable — a mismatched discriminator between instances silently breaks stored Data Protection values (see NFR-CS-02 note in `tech-stack-decisions.md`). **`CmsHostOptions` MUST NOT expose anything that changes the Data Protection application name.** This constraint carries forward into Code Generation Planning for this unit.
+
+## NFR-CS-03 — No New Security Surface (Security Baseline continuity)
+
+**Requirement**: This unit introduces no new attack surface — no new module, no new business logic, no new endpoints. Its only Security Baseline obligation is that NFR-CS-01's regression tests actually prove the existing security posture (headers, rate limiting, Data Protection, Sentry-based logging) is unchanged after the extraction.
+
+**Rationale**: Confirmed against requirements.md's Security Compliance table, where every rule applicable to the hosting/pipeline layer (SECURITY-01, 03, 04, 09, 10, 14, 15) is marked "Pre-existing, unchanged" — this unit's job is to keep that true, not to add anything new.
+
+## Out of Scope for This Unit
+
+- Database technology/connection changes — none; `Api.SlpSoftware` uses its own environment-specific connection string via the existing `dotnet-appsettings` pattern, same as `Api`/`Api.Slave` today. No new decision needed.
+- Scalability/performance targets — unchanged from today's `Api`; this unit doesn't add load, it re-composes existing middleware.
+- Availability/disaster-recovery — unchanged; no new infrastructure introduced by this unit (Infrastructure Design for this unit, next stage, covers whether `Api.SlpSoftware` as a *deployment target* needs anything new).

+# Tech Stack Decisions — Unit: SlpSoftware Client Setup
+
+## No New Technology Introduced
+
+This unit re-composes existing infrastructure (ASP.NET Core hosting, the existing `Core.Hosting.*` extension methods, the existing `ModuleOrchestrator`). No new package, framework, or external service is introduced.
+
+## Decision: `CmsHostOptions` (new, minimal)
+
+Per NFR-CS-02 (Q2 = B), `CmsHost.ConfigureServices`/`ConfigurePipeline` will accept a `CmsHostOptions` parameter.
+
+**What it must NOT contain**: anything affecting the Data Protection application discriminator (`DataProtectionExtensions.ApplicationDiscriminator`, hardcoded `"SlpModularCms"`). That constant is deliberately not configurable — an existing code comment explains that a mismatched discriminator between instances silently breaks previously-encrypted values with no visible error. `CmsHostOptions` must not reopen that risk.
+
+**Exact shape**: left open for Code Generation Planning for this unit — both current call sites (`Api`, `Api.SlpSoftware`) pass equivalent values today, so there is no concrete divergence yet to model. Introducing the parameter now (rather than later) is purely about not having to touch both `Program.cs` call sites' method signatures again the first time a real difference appears.
+
+## Decision: New Integration Test Project/Location for Pipeline Tests (NFR-CS-01)
+
+No dedicated `Api.Tests` project exists today (only module/`Core` test projects). For the new `WebApplicationFactory`-based pipeline tests:
+- Exact project placement (a new shared test project vs. extending `SlpModularCms.Core.Tests`) is a Code Generation Planning decision, not decided here — this is implementation planning, not a technology choice. Either way, `Microsoft.AspNetCore.Mvc.Testing` (the standard `WebApplicationFactory` package) is the technology being introduced; it is Microsoft's own first-party integration-testing package for ASP.NET Core, already implied by the framework version this solution targets — no new external dependency risk.
+
+## Database
+
+No change. Both `Api` and `Api.SlpSoftware` connect to MariaDB via `UseMySQL`, using their own environment-specific connection string per the existing `dotnet-appsettings` pattern (already the case for `Api`/`Api.Slave`). No new decision required for this unit.

+|---|---|---|
+| AD-1 | `CmsHost` exposes two granular methods (`ConfigureServices`, `ConfigurePipeline`) rather than one all-owning entrypoint — each Client project keeps a visible, thin `Program.cs`. | Q1 = B |
+| AD-2 | The `Offerings` module follows the Repository+Service pattern, consistent with `Modules.Master`, even though the module itself is simple CRUD. | Q2 = A |
+| AD-3 | `OfferingsController` is a single controller with per-action authorization (`[AllowAnonymous]` on the public `GET`, `AdminOnly` on everything else), not split into two controllers. | Q3 = B |
+| AD-4 | New offerings get a system-generated `Guid` `Id`, not an admin-provided slug. | Q4 = A |
+| AD-5 | Deleting an offering is a soft delete (`IsDeleted`/`DeletedAt`), filtered out of all reads — a partial, lightweight answer to the SECURITY-13 open item from requirements.md, without introducing a full audit-log mechanism. | Q5 = B |
+
+## Component Overview
+
+8 components: the shared `CmsHost` composition helper, the new `SlpModularCms.Api.SlpSoftware` Client project, and 6 components making up `SlpModularCms.Modules.Offerings` (`Offering` entity, `OfferingsDbContext`, `IOfferingRepository`/`OfferingRepository`, `IOfferingsService`/`OfferingsService`, `OfferingsController`, `OfferingsModule`).

+## Notes
+- `SlpModularCms.Core` is the shared dependency for both Client projects (`CmsHost`) but has **no** dependency in the other direction — `Core` does not reference `Modules.Offerings` or any other module, preserving the existing module-isolation pattern.
+- The Gitea Actions pipeline (external to the application dependency graph) is not shown here — its retargeting (FR-9, D-15) is an Operations-phase, deployment-time concern, not an application-level dependency.

+
+**Note**: Signatures and high-level purpose only. Detailed business rules (exact exclusivity algorithm, validation rules, reorder edge cases) are defined in Functional Design for the relevant unit (CONSTRUCTION phase).
+
+## `CmsHost` (static class, `SlpModularCms.Core.Hosting`)
+
+| Method | Input | Output | Purpose |
+|---|---|---|---|
+| `ConfigureServices` | `WebApplicationBuilder builder` | `ModuleOrchestrator` | Runs logging/Sentry setup, discovers and registers module services, registers core infrastructure (CORS, rate limiting, health checks, security headers, observability, Data Protection), and configures MVC controllers. Returns the `ModuleOrchestrator` instance so the caller can pass it into `ConfigurePipeline` after `builder.Build()`. |
+| `ConfigurePipeline` | `WebApplication app`, `ModuleOrchestrator orchestrator` | `void` | Runs the Core DB migration, wires the exception handler, security headers, rate limiter, Development-only OpenAPI/Scalar, HTTPS redirection, static content + SPA fallbacks, CORS, module middleware (`orchestrator.UseModules`), authentication/authorization, controller mapping, health checks, and the Sentry tunnel — in the exact order `Api/Program.cs` uses today, since that order encodes real constraints (documented as code comments in the current `Program.cs`). |
+
+Each project's `Program.cs` becomes:
+```csharp
+var builder = WebApplication.CreateBuilder(args);
+builder.Configuration.AddJsonFile("appsettings.local.json", optional: true, reloadOnChange: true);
+var orchestrator = CmsHost.ConfigureServices(builder);
+var app = builder.Build();

+# Components — SlpSoftware Production API
+
+## 1. `CmsHost` (new — `SlpModularCms.Core.Hosting`)
+
+**Purpose**: Shared hosting-composition logic extracted from `SlpModularCms.Api/Program.cs` (FR-3), consumed by both `SlpModularCms.Api` and `SlpModularCms.Api.SlpSoftware`.
+
+**Responsibilities**:
+- Compose the standard set of service registrations every Client project needs (logging, Sentry, module discovery, core infrastructure, CORS, rate limiting, health checks, security headers, observability, Data Protection, controllers).
+- Compose the standard HTTP pipeline every Client project needs (migrations, exception handling, security headers, rate limiting, OpenAPI/Scalar in Development, HTTPS redirection, static content, CORS, module middleware, authentication/authorization, controllers, health checks, Sentry tunnel, SPA fallbacks).
+- **Not** responsible for: bootstrapping the `WebApplicationBuilder` itself, or loading `appsettings.local.json` — those two lines stay in each project's own `Program.cs` (decision Q1 = B: two granular methods, not one entrypoint that owns everything).
+
+**Interfaces**: `ConfigureServices(WebApplicationBuilder)`, `ConfigurePipeline(WebApplication, ModuleOrchestrator)` — see component-methods.md.
+
+---
+
+## 2. `SlpModularCms.Api.SlpSoftware` (new Client project)
+
+**Purpose**: The new deployable Client (FR-1), first project in the `Clients` solution folder. Eventually the production host for `test.slpsoftware.nl` / `slpsoftware.nl` (Operations phase, D-15).
+
+**Responsibilities**:
+- Reference `SlpModularCms.Core`, `SlpModularCms.Modules.Identity`, `SlpModularCms.Modules.Availability`, `SlpModularCms.Modules.Master`, and the new `SlpModularCms.Modules.Offerings` (FR-2) — module composition is driven entirely by which Module projects are referenced (`ModuleOrchestrator` discovers modules from `.dll` files on disk, not from any list in `Program.cs`).
+- Thin `Program.cs`: bootstrap the builder, load `appsettings.local.json`, call `CmsHost.ConfigureServices`/`ConfigurePipeline`.
+- Own its own `appsettings.json` / `appsettings.Development.json` / `appsettings.local.json` (per the `dotnet-appsettings` skill pattern already used by `Api`).
+
+**Interfaces**: None beyond `Program.cs` itself — it's a composition root, not a library.
+
+---
+
+## 3. `Offering` (new entity — `SlpModularCms.Modules.Offerings.Data.Entities`)
+
+**Purpose**: The persisted record behind both the public read contract (FR-6) and admin management (FR-7).
+
+**Responsibilities**: Hold `Id` (Guid, per Q4 = A), `Title`, `Description`, `Price`, `PriceNote`, `Features` (ordered list), `CtaLabel`, `Featured`, `DisplayOrder`, `IsDeleted`, `DeletedAt` (per Q5 = B, soft delete).
+
+---
+
+## 4. `OfferingsDbContext` (new — `SlpModularCms.Modules.Offerings.Data`)
+
+**Purpose**: Module-isolated EF Core context for the `Offering` entity, following the existing per-module `DbContext` pattern (`MasterDbContext`, `AvailabilityDbContext`) — MariaDB via `UseMySQL`, its own migrations assembly.
+
+**Responsibilities**: `DbSet<Offering> Offerings`; model configuration (max lengths for `Title`/`Description`/`Price`/`PriceNote`/`CtaLabel` per SECURITY-05).
+
+---
+
+## 5. `IOfferingRepository` / `OfferingRepository` (new — `SlpModularCms.Modules.Offerings.Repositories`)
+
+**Purpose**: Data-access layer between the service and `OfferingsDbContext`, mirroring `Modules.Master`'s `ICmsInstanceRepository`/`CmsInstanceRepository` (decision Q2 = A: keep the Repository+Service pattern consistent across modules, even though this module is individually simple).
+
+**Responsibilities**: CRUD against `Offering` rows, always excluding soft-deleted rows except where the service explicitly needs them; ordering by `DisplayOrder`.
+
+---
+
+## 6. `IOfferingsService` / `OfferingsService` (new — `SlpModularCms.Modules.Offerings.Services`)
+
+**Purpose**: Business orchestration layer — the one component that knows the rules from stories.md that a repository alone shouldn't own.
+
+**Responsibilities**:
+- Enforce the "at most one featured offering" exclusivity rule (US-10) when creating/updating.
+- Own the `DisplayOrder` semantics for both reorder interactions: full-list reorder from drag-and-drop (US-08) and adjacent swap from the up/down buttons (US-09).
+- Assign `Id` (new `Guid`) and initial `DisplayOrder` (append to end) on creation.
+- Apply soft-delete (US-06/US-07 — deleting the last remaining offering is always allowed, decision Q4 in requirements.md).
+- Map between `Offering` entities and the DTOs used by the controller.
+
+---
+
+## 7. `OfferingsController` (new — `SlpModularCms.Modules.Offerings.Controllers`)
+
+**Purpose**: Single HTTP-facing component for the module (decision Q3 = B: one controller, mixed authorization per action, rather than a public/admin split into two controllers).
+
+**Responsibilities**: Expose `GET /api/v1/offerings` (`[AllowAnonymous]`, FR-6) and the admin CRUD + reorder actions (`[Authorize(Policy = "AdminOnly")]`, FR-7) on the same controller, delegating all logic to `IOfferingsService`.
+
+---
+
+## 8. `OfferingsModule` (new — `SlpModularCms.Modules.Offerings`)
+
+**Purpose**: `IModule` implementation, following the exact pattern of `MasterModule`/`AvailabilityModule`.
+
+**Responsibilities**: `RegisterServices` — register `OfferingsDbContext` (MySQL, non-locking history repository per the existing convention), `IOfferingRepository`/`OfferingRepository`, `IOfferingsService`/`OfferingsService`. `UseModule` — apply pending `OfferingsDbContext` migrations at startup.
+
+---
+
+**8 components**: 1 shared hosting component (`CmsHost`), 1 new Client project, and 6 components making up the `Offerings` module (entity, DbContext, repository, service, controller, module registration).

+# Services — SlpSoftware Production API
+
+## `IOfferingsService`
+
+**Layer**: Service (business orchestration), between `OfferingsController` and `IOfferingRepository`.
+
+**Why this service exists** (per decision Q2 = A, mirroring `ICmsInstanceService` in `Modules.Master`): the repository alone can't own the rules that span more than a single row — the "at most one featured offering" exclusivity check (US-10) reads and writes two rows in one logical operation, and both reorder interactions (US-08 full reorder, US-09 adjacent swap) recompute `DisplayOrder` across multiple rows. A controller calling the repository directly would either duplicate this orchestration or risk skipping it.
+
+**Orchestration patterns**:
+
+1. **Create/Update with featured exclusivity** (US-10): when a request sets `Featured = true`, the service first calls `GetFeaturedAsync()`; if a different offering currently holds it, that offering is un-featured (via `UpdateAsync` on it) in the same logical operation before the requested offering is saved as featured. Exact transactional boundaries (single DB transaction vs. sequential saves) are a Functional Design decision for the Offerings unit, not decided here.
+2. **Full reorder** (US-08): `ReorderAsync` receives the complete ordered list of IDs from the drag-and-drop UI and reassigns `DisplayOrder` sequentially (0, 1, 2, ...) to match.
+3. **Adjacent swap** (US-09): `MoveUpAsync`/`MoveDownAsync` locate the neighboring offering by `DisplayOrder` and swap the two `DisplayOrder` values. A no-op (or a clearly-defined error) at the boundaries (first item moving up, last item moving down) — exact behavior for an out-of-bounds call is a Functional Design detail.
+4. **Soft delete** (US-06/US-07, Q5 = B): `DeleteAsync` sets `IsDeleted = true` / `DeletedAt = now` rather than removing the row. The repository's read methods (`GetAllAsync`, `GetByIdAsync`, `GetFeaturedAsync`) always exclude soft-deleted rows, so callers never need to remember to filter — deleting the last remaining offering (US-07) is unaffected by this and remains always allowed.
+5. **Public vs. admin projections**: `GetPublicOfferingsAsync` returns `OfferingDto` (the exact FR-6 contract shape: `id`, `title`, `description`, `price`, `priceNote`, `features`, `ctaLabel`, `featured`). `GetAllForAdminAsync` returns `OfferingAdminDto`, which additionally exposes `DisplayOrder` (and, if useful in the admin UI, `IsDeleted`/`DeletedAt` are **not** exposed since deleted rows are never returned to any caller).
+
+**No other services are introduced by this feature.** `CmsHost` (components.md #1) is a static composition helper, not a service in the DI/business-orchestration sense — it has no business rules, only infrastructure wiring, so it is documented under Components/Component Methods rather than here.

+| Unit | Depends On | Nature of Dependency | Blocking? |
+|---|---|---|---|

+
+- **`SlpModularCms.Core`**: modified only by Unit 1 (the `CmsHost` addition). Unit 2 does not modify `Core`.
+- **Security Baseline compliance**: both units must satisfy their applicable rules from requirements.md's Security Compliance table independently — Unit 1 for the hosting/pipeline rules (SECURITY-03, 04, 09, 10, 14, 15 continuity), Unit 2 for the new-surface rules (SECURITY-05, 06, 08, 11, 13).
+- **No shared mutable state or runtime coupling** between the two units beyond the one-time structural dependency above — at runtime, `Offerings` is just another module discovered by `ModuleOrchestrator` inside the process Unit 1 built.

+## Unit 1: SlpSoftware Client Setup
+
+**Scope**: FR-1, FR-2, FR-3. No user stories are directly attributed to this unit (decision Q3 = A) — it is a purely technical enabling unit with no persona-facing behavior of its own.
+
+**Responsibilities**:
+- Extract the composed hosting pipeline from `SlpModularCms.Api/Program.cs` into `SlpModularCms.Core.Hosting.CmsHost`, as two methods: `ConfigureServices(WebApplicationBuilder)` and `ConfigurePipeline(WebApplication, ModuleOrchestrator)` (AD-1).
+- Repoint `SlpModularCms.Api/Program.cs` at the new shared methods, with **no behavior change** — its existing test suite must remain green.
+- Create the new `SlpModularCms.Api.SlpSoftware` project under the `Clients` solution folder, referencing `SlpModularCms.Core`, `SlpModularCms.Modules.Identity`, `SlpModularCms.Modules.Availability`, and `SlpModularCms.Modules.Master` (per FR-2). **Does not yet reference `SlpModularCms.Modules.Offerings`** — that reference is added by Unit 2, since the Offerings project doesn't exist until Unit 2 creates it.
+- Give `Api.SlpSoftware` its own `appsettings.json` / `appsettings.Development.json` / `appsettings.local.json` per the `dotnet-appsettings` skill's pattern (same as `Api`).
+
+**Components owned** (from application-design/components.md): `CmsHost`, the `SlpModularCms.Api.SlpSoftware` project shell (its `Program.cs` and `.csproj`).
+
+**Preliminary per-unit Construction assessment** (confirmed at each stage when reached, not decided here):
+- Functional Design: likely **SKIP** — no new data model or business rule, purely a hosting-composition refactor.
+- NFR Requirements / NFR Design: likely **EXECUTE** — the extraction must provably preserve `Api`'s existing security headers, rate limiting, Sentry, and Data Protection behavior (Security Baseline, D-11); this is exactly an NFR concern.
+- Infrastructure Design: likely **EXECUTE** — `Api.SlpSoftware` becoming a deployment target is new for this unit even though the underlying hosting infrastructure already exists (per the "when in doubt, execute" rule).
+- Code Generation, Build and Test: **ALWAYS**.
+

+
+## Unit 2: Offerings
+
+**Scope**: FR-4, FR-5, FR-6, FR-7, FR-8. All 12 user stories (US-01 through US-12).
+
+**Responsibilities**:
+- Create `SlpModularCms.Modules.Offerings` (+ `SlpModularCms.Modules.Offerings.Tests`) following the existing module pattern: `Offering` entity, `OfferingsDbContext`, `IOfferingRepository`/`OfferingRepository`, `IOfferingsService`/`OfferingsService`, `OfferingsController`, `OfferingsModule` (per application-design/components.md and component-methods.md).
+- Add the `<ProjectReference>` to `SlpModularCms.Modules.Offerings` in `SlpModularCms.Api.SlpSoftware.csproj` (this unit's responsibility, not Unit 1's — see plan rationale).
+- Implement the public `GET /api/v1/offerings` and the admin CRUD + reorder actions, enforcing the featured-exclusivity rule (US-10) and soft-delete semantics (AD-5).
+- No code changes for FR-8 (reference content) — the three current package values are already documented in requirements.md; the user enters them manually via the admin CRUD once built (decision D-5).
+
+**Components owned**: `Offering`, `OfferingsDbContext`, `IOfferingRepository`/`OfferingRepository`, `IOfferingsService`/`OfferingsService`, `OfferingsController`, `OfferingsModule`.
+
+**Preliminary per-unit Construction assessment**:
+- Functional Design: likely **EXECUTE** — new data model (`Offering`) and non-trivial business rules (featured exclusivity, two reorder interactions, soft delete).
+- NFR Requirements / NFR Design: likely **EXECUTE** — SECURITY-05 (input validation specifics) and the SECURITY-13 partial mitigation (soft delete) both need concrete design here.
+- Infrastructure Design: likely **SKIP** — reuses the existing MariaDB / per-module-migration infrastructure with nothing new to map (per requirements.md's Security Compliance table, SECURITY-01 is "pre-existing, unchanged" for this module).
+- Code Generation, Build and Test: **ALWAYS**.

+Unit 2 (Offerings) depends on Unit 1 (SlpSoftware Client Setup) — the `Api.SlpSoftware` project must exist before Unit 2 can add its project reference into it. Unit 1 must be built and verified (existing `Api` test suite green after the extraction) before Unit 2 starts, per the Module Update Strategy in `inception/plans/execution-plan.md`.

+# Application Design Plan — SlpSoftware Production API
+
+Dit plan beschrijft hoe de high-level applicatie-ontwerp-artefacten voor deze feature worden opgesteld. Beantwoord eerst de vragen hieronder; na jouw goedkeuring wordt het plan uitgevoerd.
+
+Context die ik al heb geverifieerd in de code (niet aangenomen):
+- `ModuleOrchestrator` (`SlpModularCms.Core/Hosting/ModuleOrchestrator.cs`) ontdekt modules **dynamisch** door `.dll`-bestanden op schijf te scannen — er is nergens een expliciete "welke modules host ik"-lijst in `Program.cs`. Dat betekent: welke modules een Client-project host, wordt volledig bepaald door welke Module-projecten dat `.csproj` referenceert, niet door code in `Program.cs` zelf.
+- `SlpModularCms.Api/Program.cs` bevat, op de bootstrap-regels na (`WebApplication.CreateBuilder`, `appsettings.local.json`), **geen enkele project-specifieke branch** — alles is generiek/config-gedreven. Dat maakt een verregaande extractie (FR-3) haalbaar.
+- `SlpModularCms.Modules.Master` volgt het patroon: `Controllers/` → `Services/` (`I{X}Service`/`{X}Service`) → `Repositories/` (`I{X}Repository`/`{X}Repository`) → `Data/{X}DbContext.cs`, plus `Models/` voor DTO's/requests en `{Module}Module.cs` (`IModule`-implementatie).
+
+## Uitvoeringschecklist
+
+- [x] Stap A — `components.md`: componenten identificeren (CmsHost-extractie, Offerings-module met sub-componenten) met verantwoordelijkheden
+- [x] Stap B — `component-methods.md`: methode-signaturen per component (geen gedetailleerde business rules — dat komt in Functional Design)
+- [x] Stap C — `services.md`: servicedefinities en orkestratiepatronen (o.a. featured-exclusiviteit, reorder-logica uit de user stories)
+- [x] Stap D — `component-dependency.md`: afhankelijkheidsmatrix + datastroom (Core ↔ Api ↔ Api.SlpSoftware ↔ Offerings)
+- [x] Stap E — `application-design.md`: consolidatie van bovenstaande in één document
+- [x] Stap F — Consistentiecontrole: komt het ontwerp overeen met requirements.md (FR-1..FR-9) en stories.md (US-01..US-12)?

+### Vraag 1 — Vorm van de `CmsHost`-extractie (FR-3)
+`Api/Program.cs` bevat, buiten de bootstrap-regels, geen project-specifieke logica. Dat maakt twee uitersten mogelijk voor de extractie.
+
+Hoe ver moet de extractie naar `SlpModularCms.Core` gaan?
+
+A) **Eén volledig entrypoint** — `CmsHost.RunAsync(string[] args)` bevat de hele samenstelling (services + pipeline + `app.Run()`); beide `Program.cs`-bestanden worden dan letterlijk een paar regels (`return CmsHost.RunAsync(args);` + evt. bootstrap-overrides). Minimaliseert duplicatie/drift maximaal, maar geeft een individueel project weinig ruimte om ooit af te wijken zonder de gedeelde methode te wijzigen.
+B) **Twee gedeelde methodes** — `CmsHost.ConfigureServices(WebApplicationBuilder)` en `CmsHost.ConfigurePipeline(WebApplication)`, die elk project vanuit zijn eigen dunne `Program.cs` aanroept (zoals vandaag al met `AddCoreInfrastructure` etc. gebeurt, maar dan als één samengestelde aanroep per fase). Iets meer code per project, maar elk project behoudt een zichtbaar `Program.cs` waarin het makkelijk is om ooit één stap toe te voegen/over te slaan zonder `Core` te wijzigen.
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: B
+
+### Vraag 2 — Architectuurpatroon voor de Offerings-module
+`Modules.Master` gebruikt een Repository+Service-laag (`ICmsInstanceRepository` → `ICmsInstanceService` → Controller). Bij Requirements Analysis heb je de Property-Based Testing-extensie overgeslagen met als reden dat dit een eenvoudige CRUD-achtige module is zonder significante bedrijfslogica.
+
+Moet de Offerings-module hetzelfde Repository+Service-patroon volgen (consistent met Master), of is dat voor deze module onnodige indirectie?
+
+A) Repository+Service (consistent met Master) — `IOfferingRepository` + `IOfferingsService`, ook al is de module zelf simpel
+B) Alleen Service, geen Repository — `IOfferingsService` praat direct met `OfferingsDbContext` (minder indirectie voor een module die je zelf als eenvoudige CRUD hebt gekarakteriseerd)
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: A
+
+### Vraag 3 — Controllersplitsing publiek vs. admin
+Requirements.md scheidt al duidelijk het publieke `GET /api/v1/offerings` (FR-6, anoniem) van de admin-CRUD (FR-7, `AdminOnly`).
+
+Moet dit ook twee aparte controllers worden, of één controller met gemengde autorisatie per actie?
+
+A) Twee controllers — `OfferingsController` (publiek, alleen `GET`) en `OfferingsAdminController` (CRUD + reorder, `AdminOnly`) — duidelijke scheiding, moeilijker om per ongeluk een admin-actie anoniem te laten
+B) Eén controller — `OfferingsController` met `[AllowAnonymous]` op de publieke `GET` en `[Authorize(Policy = "AdminOnly")]` op de rest
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: B
+
+### Vraag 4 — Id-strategie voor nieuw aangemaakte offerings
+De drie bestaande referentiewaarden (FR-8) gebruiken leesbare slugs (`pakket_01`, `pakket_02`, `pakket_03`). Het publieke contract (FR-6) verwacht een `string`-veld `id`, dus zowel een GUID als een handmatige slug is technisch mogelijk.
+
+Hoe moet de `Id` van een **nieuw** aangemaakte offering tot stand komen?
+
+A) Automatisch gegenereerd (GUID as string) — simpel, geen validatie op uniekheid/formaat nodig, consistent met andere entiteiten in dit systeem (bijv. `CmsInstance.Id`)
+B) Door de CMS Administrator zelf opgegeven als leesbare slug — consistent met de bestaande `pakket_XX`-stijl, vereist wel validatie (uniek, toegestane tekens)
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: A
+
+### Vraag 5 — Verwijdersemantiek
+Requirements.md signaleert een nog open punt bij SECURITY-13 (audit-trail op content-mutaties). US-06/US-07 beschrijven "verwijderen" zonder te specificeren of dat een echte database-delete is of een soft-delete.
+
+Hoe moet "een offering verwijderen" op databaseniveau werken?
+
+A) Hard delete — de rij wordt echt verwijderd uit `OfferingsDbContext`; simpelst, maar draagt niet bij aan het SECURITY-13-openpunt
+B) Soft delete — een `IsDeleted`/`DeletedAt`-veld, verwijderde offerings worden uit alle queries gefilterd maar blijven in de database staan; simpele, gedeeltelijke invulling van het SECURITY-13-openpunt (geen volledige audit trail, maar wel behoud van de laatste staat vóór verwijdering)
+X) Anders (beschrijf hieronder na de [Answer]:-tag)

+# Execution Plan — SlpSoftware Production API
+
+## Detailed Analysis Summary
+
+### Transformation Scope (Brownfield)
+- **Transformation Type**: Architectural addition, not a rewrite — a new deployable Client project is added alongside the existing one, a piece of existing hosting logic is extracted into a shared location, and one new module is added. No existing deployment model changes (still a single self-hosted ASP.NET Core process per environment).
+- **Primary Changes**: (1) Extract `SlpModularCms.Api/Program.cs`'s composed hosting pipeline into `SlpModularCms.Core` (`CmsHost.Configure(...)`); (2) new `SlpModularCms.Api.SlpSoftware` Client project consuming that shared method; (3) new `SlpModularCms.Modules.Offerings` module (entity, `DbContext`, public endpoint, admin CRUD); (4) Operations-phase CI/CD cutover of the existing pipeline from `Api` to `Api.SlpSoftware`.
+- **Related Components**: `SlpModularCms.Core` (extraction target + hosts the `Offering`-adjacent shared conventions), `SlpModularCms.Api` (must keep working identically after the extraction — it is not itself changing behavior), the existing Gitea Actions pipeline (`gitea-deployment-workflow` feature's artifacts).
+
+### Change Impact Assessment
+- **User-facing changes**: Yes — new admin CRUD screens for the CMS Administrator persona, and new dynamic (CMS-managed) content on the live website for the Site Visitor persona (requirements.md FR-6, FR-7; stories.md US-01..US-12).
+- **Structural changes**: Yes — first-ever project in the `Clients` solution folder; new shared hosting-composition method in `Core`; new module following the existing `IModule` pattern.
+- **Data model changes**: Yes — new `Offering` entity + `OfferingsDbContext` (FR-5), isolated per the existing per-module migration pattern.
+- **API changes**: Yes — new public `GET /api/v1/offerings` (FR-6) and new authenticated admin endpoints (FR-7).
+- **NFR impact**: Yes — Security Baseline extension is enabled and blocking (D-11); the hosting-pipeline extraction (FR-3) must preserve `Api`'s existing security headers/rate limiting/Sentry/Data Protection behavior exactly, so it doesn't regress the already-hardened dev host while building the new one on the same foundation.

+
+Text alternative: `Core` provides the shared `CmsHost.Configure` method to both the existing `Api` (unchanged behavior) and the new `Api.SlpSoftware` (blue = shared foundation, green = existing/unchanged components, yellow = new components, purple = the externally-owned CI/CD pipeline that gets retargeted in the Operations phase).
+
+- **Primary Component**: `SlpModularCms.Modules.Offerings` (new) and `SlpModularCms.Api.SlpSoftware` (new)
+- **Infrastructure Components**: `.gitea/workflows/continuous_integration.yaml`, `.gitea/workflows/deploy-scp.yaml`, `operations/deployment/deployment-instructions.md` (all owned by `gitea-deployment-workflow`; extended, not duplicated, per D-7/D-15)
+- **Shared Components**: `SlpModularCms.Core` (new `CmsHost.Configure(...)`), `SlpModularCms.Modules.Identity`, `SlpModularCms.Modules.Availability`, `SlpModularCms.Modules.Master` (all hosted, unchanged)
+- **Dependent Components**: `SlpModularCms.Api` — does not change behavior, but depends on the FR-3 extraction being behavior-preserving
+- **Supporting Components**: Existing Sentry-based logging/alerting, existing `HierarchicalRoleHandler`/`AdminOnly` policy
+
+| Related Component | Change Type | Change Reason | Change Priority |
+|---|---|---|---|
+| `SlpModularCms.Core` | Minor (additive extraction) | FR-3 shared hosting composition | Critical (blocks both Client projects) |
+| `SlpModularCms.Api` | Configuration-only (calls the new shared method instead of inline code) | FR-3 | Critical (regression risk if behavior changes) |
+| `SlpModularCms.Api.SlpSoftware` | Major (new project) | FR-1, FR-2 | Critical |
+| `SlpModularCms.Modules.Offerings` (+ Tests) | Major (new module) | FR-4, FR-5 | Critical |
+| Gitea Actions pipeline | Minor (retarget existing jobs) | FR-9, D-15 | Important (Operations phase only, not blocking Construction) |
+
+### Risk Assessment
+- **Risk Level**: **Medium** — multiple components change, but each is independently testable (the `Core` extraction can be verified against `Api`'s existing test suite before `Api.SlpSoftware` is even built on top of it), and the highest-risk step (the CI/CD cutover, D-15) is isolated to the Operations phase, coordinated with the feature that already owns that pipeline rather than a fresh, unreviewed change.
+- **Rollback Complexity**: Moderate — the `Core` extraction is a straightforward revert if `Api`'s behavior regresses (git revert, `Api.SlpSoftware` didn't exist to depend on it yet at that point in the sequence). The pipeline cutover (Operations) is a config change to Gitea Actions YAML, revertible the same way.
+- **Testing Complexity**: Moderate — needs before/after regression coverage on `Api` for the extraction (NFR impact on security headers/rate limiting/Sentry/Data Protection continuity), plus new unit/integration tests for the `Offerings` module.
+
+---
+
+## Module Update Strategy
+
+- **Update Approach**: Sequential where dependencies require it, then parallel-capable.
+  1. **Foundation first**: Extract `CmsHost.Configure(...)` into `Core` and repoint `SlpModularCms.Api/Program.cs` at it, **verifying `Api`'s existing behavior and test suite are unaffected** before building anything new on top of the shared method.
+  2. **Then, in parallel**: create `SlpModularCms.Api.SlpSoftware` (consuming the now-shared method + existing modules) and build out `SlpModularCms.Modules.Offerings` — these two do not depend on each other's internals, only on the foundation from step 1 and on `Api.SlpSoftware` existing as *a* host by the time `Offerings` needs to be wired in.
+  3. **Operations last**: CI/CD cutover (D-15) only after Construction (Code Generation + Build and Test) has proven both the extraction and the new module.
+- **Critical Path**: The `Core` extraction (step 1) — both the new Client project and the continued correctness of the existing dev host depend on it.
+- **Coordination Points**: The shared `CmsHost.Configure(...)` signature (must accommodate `Api`'s and `Api.SlpSoftware`'s differing module lists); the CI/CD pipeline hand-off with `gitea-deployment-workflow` (extend existing jobs, don't fork them).
+- **Testing Checkpoints**: (a) After the `Core` extraction — full existing `Api` test suite + a manual/automated smoke check that `Api` still serves `/admin`, static content, health checks, and security headers identically. (b) After `Offerings` module code generation — its own unit/integration tests (NFR-2). (c) After both units — full Build and Test phase covering `Api.SlpSoftware` end-to-end. (d) Before the Operations cutover — confirm `Api.SlpSoftware` has been running successfully (e.g. against `test.slpsoftware.nl`) prior to repointing production.
+
+**Exact unit boundaries and naming are finalized in the Units Generation stage** (next after Application Design); this section states the intended dependency order that Units Generation should respect, not the final unit list.

+
+## Phases to Execute
+
+### 🔵 INCEPTION PHASE
+- [x] Workspace Detection (COMPLETED)
+- [x] Reverse Engineering (COMPLETED — reused existing `_shared/reverse-engineering/` artifacts, no rerun)
+- [x] Requirements Analysis (COMPLETED)
+- [x] User Stories (COMPLETED)
+- [x] Workflow Planning / Execution Plan (COMPLETED — this document)
+- [ ] Application Design — **EXECUTE**
+  - **Rationale**: New components are introduced (`Offering` entity, `OfferingsDbContext`, admin CRUD service layer, the shared `CmsHost.Configure(...)` method) whose methods, business rules (featured exclusivity, reorder persistence), and dependencies need definition before units can be planned.
+- [ ] Units Planning — **EXECUTE**
+  - **Rationale**: Multiple modules/projects are involved (Core extraction, new Client project, new module) with a real dependency order (Module Update Strategy above) — this needs explicit unit boundaries, not an implicit single unit.
+- [ ] Units Generation — **EXECUTE**
+  - **Rationale**: Same as Units Planning — this is a multi-unit change, not a single simple unit.
+
+### 🟢 CONSTRUCTION PHASE
+*(Assessed per unit once Units Generation defines them; overall expectation below.)*
+- [ ] Functional Design — **EXECUTE** (primarily for the Offerings unit: new data model + business rules; likely minimal/skippable for a pure hosting-extraction unit — confirmed per-unit)
+  - **Rationale**: New data model (`Offering`) and non-trivial business rules (exactly-one-featured, reorder semantics) need detailed design.
+- [ ] NFR Requirements — **EXECUTE**
+  - **Rationale**: Security Baseline extension is enabled and blocking (D-11); the hosting-extraction unit specifically carries NFR risk (must not regress `Api`'s existing security headers/rate limiting/Sentry/Data Protection).
+- [ ] NFR Design — **EXECUTE**
+  - **Rationale**: Follows directly from NFR Requirements being executed.
+- [ ] Infrastructure Design — **EXECUTE** (primarily for the Client/hosting unit: `Api.SlpSoftware` is a new deployment target; likely skippable for the Offerings unit, which reuses the existing MariaDB/module-migration infrastructure with nothing new to map)
+  - **Rationale**: `Api.SlpSoftware` becoming a deployment target is new for this specific unit, even though the underlying hosting infrastructure (Pi, Gitea) already exists — per the "when in doubt, execute" rule for infra that's new to *this* unit.
+- [ ] Code Generation — **EXECUTE (ALWAYS)**
+  - **Rationale**: Implementation planning and code generation needed for every unit.
+- [ ] Build and Test — **EXECUTE (ALWAYS)**
+  - **Rationale**: Full build across units together, plus integration testing between the new module, the new Client project, and the unchanged `Api`.
+
+### 🟡 OPERATIONS PHASE
+- [ ] Deployment Setup — **EXECUTE** (asks its own inclusion question when reached, per the workflow's standard pattern)
+  - **Rationale**: D-7/D-15 — the CI/CD pipeline cutover from `Api` to `Api.SlpSoftware` is explicitly in scope for this feature's Operations phase.
+- [ ] Monitoring Setup — **EXECUTE** (asks its own inclusion question when reached)
+  - **Rationale**: The new public endpoint and admin CRUD are new surfaces on what will become the production API; worth confirming the existing Sentry-based monitoring (inherited via FR-3) covers them, or whether anything additional is needed.
+- [ ] Production Readiness Validation — **EXECUTE (ALWAYS, once Operations phase is reached)**
+  - **Rationale**: Standard wrap-up gate, including the Security Baseline final check and (per this repo's convention) the `dotnet-appsettings` compliance check for the new Client project.
+
+---
+
+## Package Change Sequence (Brownfield)
+
+1. **`SlpModularCms.Core`** — add `CmsHost.Configure(...)` (or equivalent), extracted from `SlpModularCms.Api/Program.cs`. *Must land first; blocks everything else.*
+2. **`SlpModularCms.Api`** — repoint `Program.cs` at the new shared method. *No behavior change; verify via existing tests before proceeding.*
+3. **`SlpModularCms.Api.SlpSoftware`** (new) and **`SlpModularCms.Modules.Offerings`** (+ `.Tests`, new) — can proceed once steps 1-2 are verified; independent of each other internally, both needed before Build and Test can exercise the full stack.
+4. **Gitea Actions pipeline** (`continuous_integration.yaml`, `deploy-scp.yaml`, `deployment-instructions.md`) — retargeted in the Operations phase only, after Construction has proven steps 1-3.
+
+*(Final unit grouping is confirmed in Units Generation — this is the dependency-respecting order that stage should produce.)*
+
+---
+
+## Estimated Timeline
+- **Total Phases**: 3 (Inception remainder, Construction, Operations)
+- **Estimated Duration**: Not tracked in calendar time for this workflow — driven by stage-by-stage approval, not a schedule.
+
+## Success Criteria
+- **Primary Goal**: `SlpModularCms.Api.SlpSoftware` exists, hosts Core/Identity/Availability/Master/Offerings, serves the public `GET /api/v1/offerings` and authenticated admin CRUD, without regressing `SlpModularCms.Api`.
+- **Key Deliverables**: Shared `CmsHost.Configure(...)` in `Core`; `SlpModularCms.Api.SlpSoftware` project in `Clients`; `SlpModularCms.Modules.Offerings` (+ `.Tests`) in `Application/Modules` / `Tests/Modules`; documented reference content (FR-8); retargeted CI/CD pipeline (Operations).
+- **Quality Gates**: Full Security Baseline compliance (per requirements.md); `Api`'s existing test suite green after the extraction; new module's own test coverage (NFR-2); Build and Test phase integration checks.
+- **Integration Testing**: `Api.SlpSoftware` serving all five modules together, same-origin site + `/admin` + `/api/v1`, matches `Api`'s existing behavior for the four pre-existing modules.
+- **Operational Readiness**: CI/CD pipeline successfully building/deploying `Api.SlpSoftware`; monitoring/alerting confirmed to cover the new surfaces.

+# Story Generation Plan — SlpSoftware Production API
+
+Dit plan beschrijft hoe de user stories en persona's voor deze feature worden opgesteld. Beantwoord eerst de vragen hieronder; na jouw goedkeuring wordt dit plan stap voor stap uitgevoerd.
+
+## Uitvoeringschecklist
+
+- [x] Stap A — Persona's definiëren (`personas.md`): Site Visitor (anonieme bezoeker marketingsite) en CMS Administrator (Administrator-rol, beheert offerings via `/admin`)
+- [x] Stap B — Stories voor de Site Visitor-persona (consumptie van `GET /api/v1/offerings`, incl. leeg-resultaat-scenario)
+- [x] Stap C — Stories voor de CMS Administrator-persona (aanmaken, bewerken, verwijderen, herordenen van offerings, incl. de "featured"-regel)
+- [x] Stap D — Acceptatiecriteria per story toevoegen (Given/When/Then, zie Vraag 2)
+- [x] Stap E — Persona's koppelen aan bijbehorende stories
+- [x] Stap F — Zelfcontrole: elke story voldoet aan INVEST (Independent, Negotiable, Valuable, Estimable, Small, Testable)
+- [x] Stap G — `stories.md` en `personas.md` opslaan onder `aidlc-docs/features/slpsoftware-api/inception/user-stories/`
+
+## Aanpak-opties voor storyopbouw
+
+- **Persona-based** (aanbevolen): stories gegroepeerd per persona (Site Visitor / CMS Administrator) — sluit direct aan op de twee duidelijk verschillende gebruikersrollen uit requirements.md.
+- **Feature-based**: stories gegroepeerd per capability (lezen, aanmaken, bewerken, verwijderen, herordenen) ongeacht wie de actor is.
+- **Hybride**: epics per persona, met feature-based sub-stories eronder.
+
+---
+
+## Vragen
+
+### Vraag 1 — Storyopbouw
+Welke aanpak voor het groeperen van de stories heeft je voorkeur?
+
+A) Persona-based (aanbevolen) — twee groepen: Site Visitor en CMS Administrator
+B) Feature-based — gegroepeerd per capability (lezen/aanmaken/bewerken/verwijderen/herordenen)
+C) Hybride — epics per persona met feature-based sub-stories
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: a
+
+### Vraag 2 — Detailniveau acceptatiecriteria
+Welk format voor acceptatiecriteria per story?
+
+A) Given/When/Then (aanbevolen — direct bruikbaar als testscenario in latere fases)
+B) Simpele bullet-checklist per story (sneller te lezen, minder gestructureerd)
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: A
+
+### Vraag 3 — "Exactly one featured" regel
+De externe hand-off-doc noemt: "Exactly one package in the list should have `featured: true`" — maar de frontend handhaaft dit niet zelf. Moet de admin-CRUD (bij het aanmaken/bewerken) dit afdwingen?
+
+A) Ja — bij het instellen van `featured` op een offering wordt automatisch de vorige featured-offering ontfeatured (systeem garandeert altijd precies 0 of 1 featured item)
+B) Nee — geen afdwinging; de admin is zelf verantwoordelijk, het systeem staat 0, 1 of meerdere featured offerings toe
+C) Waarschuwen, niet blokkeren — het systeem staat meerdere featured offerings toe maar toont een duidelijke waarschuwing in de admin-UI
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: A
+
+### Vraag 4 — Lege lijst op de publieke endpoint
+Wat moet er gebeuren als de admin alle offerings verwijdert, zodat `GET /api/v1/offerings` een lege array `[]` teruggeeft?
+
+A) Toestaan — een lege array is een geldige response; de marketingsite toont dan geen pakket-cards (frontend-verantwoordelijkheid, niet iets wat de API moet voorkomen)
+B) Voorkomen — de admin kan de laatste overgebleven offering niet verwijderen (systeem blokkeert dit met een duidelijke foutmelding)
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]:A
+
+### Vraag 5 — Herordenen (reorder)
+Hoe moet de admin de volgorde van offerings (het `DisplayOrder`-veld uit FR-5) kunnen aanpassen?
+
+A) Drag-and-drop in de lijst-view van de admin-UI
+B) Expliciete "omhoog"/"omlaag"-knoppen per rij
+C) Een numeriek volgorde-veld dat de admin direct invult bij het aanmaken/bewerken
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: A en B
+

+# Unit of Work Plan — SlpSoftware Production API
+
+Dit plan beschrijft hoe het systeem wordt opgedeeld in units of work voor de Construction-fase. Beantwoord eerst de vragen; na goedkeuring wordt het plan uitgevoerd.
+
+**Al besliste punten, hier niet opnieuw bevraagd** (met onderbouwing waarom een vraag overbodig zou zijn):
+- **Volgorde tussen units**: al vastgelegd in `inception/plans/execution-plan.md` (Module Update Strategy) — de Foundation-unit (Core-extractie + `Api.SlpSoftware`-skelet) moet eerst landen en geverifieerd worden tegen `Api`'s bestaande gedrag, vóórdat de Offerings-unit erbovenop gebouwd wordt. Geen nieuwe ambiguïteit sinds die analyse.
+- **Wie voegt de project-reference naar `Modules.Offerings` toe aan `Api.SlpSoftware.csproj`**: dit moet de Offerings-unit zelf doen (niet de Foundation-unit), simpelweg omdat die referentie niet kan compileren vóórdat het Offerings-project bestaat. Geen keuzevraag, een logische noodzaak.
+- **Teamafstemming (Team Alignment-categorie)**: N/A — dit is een solo-project (jij bent de enige ontwikkelaar/reviewer), er zijn geen team-ownership-grenzen te bepalen.
+- **Code-organisatiestrategie (greenfield-only categorie)**: N/A — dit is een brownfield-feature; de mapstructuur ligt al vast via `CLAUDE.md`/`AGENTS.md` (Application/Modules, Tests/Modules, Clients).
+
+## Uitvoeringschecklist
+
+- [x] Stap A — `unit-of-work.md`: unit-definities en verantwoordelijkheden
+- [x] Stap B — `unit-of-work-dependency.md`: afhankelijkheidsmatrix tussen units
+- [x] Stap C — `unit-of-work-story-map.md`: koppeling van elke user story (US-01..US-12) en relevante FR's aan een unit
+- [x] Stap D — Valideren: zijn alle stories toegewezen, kloppen de grenzen met application-design.md?
+
+---
+
+## Vragen
+
+### Vraag 1 — Unit-indeling
+Op basis van requirements.md en application-design.md stel ik twee units voor: **Foundation** (`CmsHost`-extractie in Core + het `Api.SlpSoftware`-projectskelet, FR-1/FR-2/FR-3) en **Offerings** (de volledige nieuwe module, FR-4 t/m FR-8, alle 12 user stories). Dit sluit aan bij de Module Update Strategy uit Workflow Planning: Foundation moet eerst en heeft het meeste regressierisico op de bestaande `Api`; Offerings is de nieuwe, op zichzelf staande module.
+
+Welke indeling heeft je voorkeur?
+
+A) Twee units (aanbevolen) — Foundation en Offerings, zoals hierboven beschreven
+B) Eén gecombineerde unit — alles in één keer (Core-extractie, nieuw project, nieuwe module) als één ontwerp/codegeneratie-traject
+C) Drie units — Foundation opsplitsen in "Core-extractie" en "Api.SlpSoftware-projectskelet" als aparte units
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: A
+
+### Vraag 2 — Naamgeving van de units
+Bij optie A of C hierboven, welke namen passen het best?
+
+A) "Client Hosting Foundation" en "Offerings Module" (technisch, beschrijft wat de unit doet)
+B) "SlpSoftware Client Setup" en "Offerings" (korter, gekoppeld aan het eindresultaat)
+X) Anders (geef zelf namen op na de [Answer]:-tag)
+
+[Answer]: B
+
+### Vraag 3 — Unit zonder eigen user stories
+De Foundation-unit host geen enkele van de 12 user stories rechtstreeks (die horen allemaal bij de Offerings-functionaliteit) — Foundation bestaat puur om FR-1/FR-2/FR-3 (nieuw project + gedeelde hosting-extractie) te realiseren, zonder zichtbaar persona-voordeel op zich.
+
+Is het acceptabel dat een unit in `unit-of-work-story-map.md` geen enkele story toegewezen krijgt (wel FR's), of geef je de voorkeur aan een andere aanpak?
+
+A) Ja, prima — Foundation krijgt FR-1/FR-2/FR-3 toegewezen in de story-map, geen user stories; dat is een geldige, verwachte situatie voor een puur technische enabling-unit
+B) Nee — voeg Foundation samen met Offerings tot één unit, zodat elke unit minstens één user story heeft (impliceert antwoord B bij Vraag 1)

+# User Stories Assessment
+
+## Request Analysis
+- **Original Request**: New `SlpModularCms.Api.SlpSoftware` client hosting a new `SlpModularCms.Modules.Offerings` module: a public unauthenticated `GET /api/v1/offerings` endpoint plus admin CRUD (create/edit/delete/reorder) for offering content.
+- **User Impact**: Direct — two distinct user types interact with this feature: anonymous website visitors (consumers of the public endpoint, indirectly via the external frontend) and CMS administrators (direct users of the new admin CRUD screens).
+- **Complexity Level**: Complex (per requirements.md Intent Analysis)
+- **Stakeholders**: The user (product owner + sole admin operator today), plus the external `SlpSoftware` frontend as a technical consumer of the public contract.
+
+## Assessment Criteria Met
+- [x] High Priority: **New User Features** — the admin CRUD screens are entirely new functionality (requirements FR-7).
+- [x] High Priority: **Customer-Facing APIs** — `GET /api/v1/offerings` is consumed by an external system (requirements FR-6).
+- [x] High Priority: **Multi-Persona Systems** — anonymous site visitor vs. authenticated CMS administrator have different needs and acceptance criteria.
+- [x] Medium Priority / Complexity Assessment: **Ambiguity** — requirements intentionally left some admin-UX details open (e.g. how "featured" exclusivity and reordering are enforced), which acceptance criteria can resolve concretely.
+- [x] Benefits: Clear acceptance criteria for the "exactly one featured" business rule (hand-off doc) and for delete/reorder edge cases, which are exactly the kind of detail that's easy to get wrong without a story-level decision.
+
+## Decision
+**Execute User Stories**: Yes
+**Reasoning**: Meets multiple High Priority criteria outright (new user-facing admin feature, customer-facing API, multi-persona), and there are genuine open UX/business-rule questions (featured-flag exclusivity, empty-state handling, reorder UX) that are better resolved as acceptance criteria now than left ambiguous into Application Design or Code Generation.
+
+## Expected Outcomes
+- A concrete, testable acceptance-criteria decision for the "exactly one featured offering" rule (currently only a soft expectation in the external hand-off doc).
+- A concrete decision for what happens to the public endpoint when zero offerings exist.
+- A concrete decision for the reorder interaction/persistence model, feeding directly into FR-5's `DisplayOrder` field and FR-7's admin CRUD design.
+- Two clear personas (Site Visitor, CMS Administrator) that later design/code-generation stages can reference instead of re-deriving "who is this for" each time.

+# Requirements Clarification Questions — SlpSoftware Production API
+
+Vul je keuze in achter elke `[Answer]:`-tag. Kies de laatste optie (`Anders`) als niets past en beschrijf dan je voorkeur.
+
+Waar ik iets al uit de code, de solution-structuur of de externe handoff-doc kon opmaken, staat dat als context boven de vraag — dan hoef je vaak alleen te bevestigen of te corrigeren.
+
+---
+
+## A. Verhouding tussen `SlpModularCms.Api` en de nieuwe `SlpModularCms.Api.SlpSoftware`
+
+### Question 1
+**Context**: ik heb de `.sln` nagekeken. De **Clients**-solution folder bestaat al, maar bevat momenteel **nul projecten** — hij staat leeg te wachten. `SlpModularCms.Api` en `SlpModularCms.Api.Slave` zitten vandaag allebei onder **Application** (samen met `Core` en de `Modules`-submap), precies zoals `CLAUDE.md` het beschrijft: "Development versions of the applications". M.a.w.: de structuur is al voorbereid op precies deze feature.
+
+Klopt mijn lezing dat `SlpModularCms.Api.SlpSoftware` het **eerste** project wordt dat ooit in Clients komt, en dat `SlpModularCms.Api` gewoon blijft staan waar hij staat (Application, ongewijzigde rol als dev-host)?
+
+A) Ja — klopt precies zo
+B) Nee — `SlpModularCms.Api` moet zelf verplaatst/hernoemd worden naar Clients in plaats van een apart nieuw project
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: A
+
+### Question 2
+**Context**: `SlpModularCms.Api` host vandaag vier modules: Core, Identity, Availability en Master (zie `Program.cs` / module-orchestrator). De admin-CMS (login, content-beheer) heeft dus sowieso auth (Identity) en de bestaande availability-gate nodig.
+
+Moet `SlpModularCms.Api.SlpSoftware` dezelfde vier modules hosten (Core + Identity + Availability + Master) plus de nieuwe module, of ontbreekt er iets bewust?
+
+A) Ja — zelfde vier modules + de nieuwe module
+B) Nee, er moet iets weg of anders (beschrijf hieronder)
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: A
+
+### Question 3
+**Context**: `SlpModularCms.Api/Program.cs` bevat inmiddels een flinke samengestelde pipeline (static content + SPA-fallback voor `/admin` én `wwwroot/web/`, health checks, security headers/CSP, rate limiting, Sentry, Data Protection, startup-migraties, module-orchestrator) — grotendeels gebouwd tijdens de `gitea-deployment-workflow`-feature. Als `SlpModularCms.Api.SlpSoftware` straks hetzelfde moet doen, kan dat op twee manieren.
+
+Hoe wil je omgaan met deze hosting-/pipeline-code tussen de twee Client-projecten?
+
+A) Extraheer de gedeelde samenstelling naar een herbruikbare methode in `SlpModularCms.Core` (bijv. iets als `CmsHost.Configure(...)`), zodat beide `Program.cs`-bestanden dun blijven en niet uit elkaar kunnen groeien — kost wat refactorwerk nu, maar voorkomt duplicatie en drift
+B) Dupliceer `Program.cs` gewoon naar het nieuwe project (sneller nu, maar toekomstige pipeline-wijzigingen moeten dan op twee plekken worden doorgevoerd)
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: A
+
+---
+
+## B. Scope van de nieuwe module (op basis van `packages-api-handoff.md`)
+
+### Question 4
+**Context**: de handoff-doc in de andere workspace vraagt letterlijk alleen om een publieke, unauthenticated `GET /api/v1/packages` — geen mutatie-endpoints, "CMS authoring is out of scope for the marketing site itself" staat er expliciet bij. Maar de hele reden dat dit een CMS-endpoint wordt (in plaats van hardcoded blijven) is dat de content beheerbaar moet zijn.
+
+Wat moet deze feature opleveren voor het **beheren** van package-content?
+
+A) Alleen de publieke `GET`-endpoint + geseede content (exact zoals de handoff vraagt) — CRUD/admin-UI voor packages is een latere, aparte feature
+B) Ook admin-CRUD nu meenemen (aanmaken/bewerken/verwijderen/herordenen van packages via de admin-SPA), zodat er direct een reden is dat dit "CMS-beheerd" is
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: B
+
+### Question 5
+**Context**: de handoff-doc noemt `content.ts` (in de andere workspace) als bron van de drie huidige, live pakketten (`pakket_01` Landingspagina, `pakket_02` Website, `pakket_03` Maatwerk) en zegt expliciet: gebruik dat bestand als seed-data zodat de site niet verandert zodra het endpoint live gaat.
+
+Moet deze feature die drie pakketten automatisch seeden (bijv. via een EF-migratie of startup-seed), of is handmatige invoer later acceptabel?
+
+A) Automatisch seeden met de exacte waarden uit de handoff-doc (ik geef de drie teksten door / je leest ze uit de referentie-workspace)
+B) Niet automatisch seeden — content komt er later handmatig in
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: x, ik doe het zelf, maar wil wel beginnen met de waarden die nu worden gebruikt dus dat moet wel ergens vast worden gelegd/worden behouden.
+
+### Question 6
+**Context**: de handoff-doc noemt als open item dat er een nginx `location /api/v1/ { proxy_pass ... }` moet worden toegevoegd, omdat die workspace er vanuit gaat dat de Pi's vandaag alleen statische bestanden serveren. Maar in **dit** repo (zie `WEBSITE_WORKSPACE.md` en de — grotendeels al gemergde — `gitea-deployment-workflow`-feature) wordt de site (`wwwroot/web/`) al same-origin door **dezelfde** Client-API geserveerd die ook `/api/v1` en `/admin` bedient; er is dus al geen aparte nginx-proxy voor de API nodig zodra die Client-API de gedeployde host is.
+
+Klopt mijn lezing dat dit "open item" uit de externe handoff-doc bij ons al is opgelost door de bestaande architectuur, zodra `SlpModularCms.Api.SlpSoftware` de gedeployde host wordt — en dat er dus geen extra nginx-wijziging nodig is?
+
+A) Ja, klopt — geen extra nginx-config nodig, zolang de juiste Client-API wordt gedeployed
+B) Nee, er zit een addertje onder het gras (beschrijf hieronder)
+X) Anders / weet ik niet zeker — laten we dit samen checken tegen de echte nginx-config op de Pi
+
+[Answer]: A
+
+---
+
+## C. Deploy-retarget en levenscyclus van `SlpModularCms.Api`
+
+### Question 7
+**Context**: je zei dat `Api.SlpSoftware` "uiteindelijk" de gedeployde API moet worden — dat klinkt alsof het omzetten van de CI/CD-pipeline (`.gitea/workflows/deploy-scp.yaml`, `continuous_integration.yaml`, en `deployment-instructions.md` — allemaal eigendom van de `gitea-deployment-workflow`-feature, momenteel gericht op `SlpModularCms.Api`) niet per se in déze feature hoeft te zitten.
+
+Hoort het daadwerkelijk omzetten van de CI/CD-pipeline naar `Api.SlpSoftware` bij deze feature (Operations-fase), of is dat expliciet een latere, aparte stap?
+
+A) Ja, neem de CI/CD-omzetting mee in de Operations-fase van déze feature (uitbreiden op de bestaande pipeline, niet dupliceren)
+B) Nee — deze feature levert alleen het nieuwe project + de nieuwe module op; de omzetting van de pipeline is een aparte, latere feature
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: A
+
+### Question 8
+Moet `SlpModularCms.Api` (de huidige dev-host) op termijn verdwijnen zodra `Api.SlpSoftware` bewezen in productie draait, of blijft hij net als `Api.Slave` gewoon permanent bestaan als lokale dev-tool?
+
+A) `SlpModularCms.Api` blijft permanent bestaan als lokale dev-host (zelfde rol als vandaag, geen verwijdering gepland)
+B) `SlpModularCms.Api` is op termijn kandidaat om verwijderd te worden — noteer dit als toekomstige tech debt, niet nu oppakken
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: A
+
+---
+
+## D. Naming en techniek van de nieuwe module
+
+### Question 9
+Hoe moet de nieuwe module heten? Op basis van de scope (package/pricing-kaarten voor de marketingsite) stel ik `SlpModularCms.Modules.Packages` voor.
+
+A) `SlpModularCms.Modules.Packages` (aanbevolen — beschrijft het domein, niet de specifieke site)
+B) `SlpModularCms.Modules.SlpSoftware` (koppelt de module aan de site zelf i.p.v. aan het domeinconcept)
+X) Anders (geef zelf een naam op na de [Answer]:-tag)
+
+[Answer]: A, al lijkt het me iets te generiek. Als je de naam leest zou hetr zomaar kunnen zijn dat ik het in de toekomst lees als andere packages. als een soort library module. Het is een dienst of service die je ermee moet aanleveren. Het is nu voor SlpSoftware, maar later wil ik het ook kunnen hergebruiken voor bijvoorbeeld een klant die fotografie doet en fotoshoot verkoopt. Dan wil ik deze module kunnen hergebruiken. Kan je eventueel nog wat andere suggesties doen?
+
+### Question 10
+**Context**: `Availability` en `Master` hebben allebei hun eigen `DbContext` (module-isolatie is het bestaande patroon), draaiend op MariaDB via EF Core.
+
+Moet de nieuwe module z'n eigen `DbContext` krijgen (zelfde isolatie-patroon), of past het beter bij een bestaande context?
+
+A) Eigen `DbContext` (bijv. `PackagesDbContext`), consistent met Availability/Master
+B) Hergebruik een bestaande `DbContext` (geef aan welke)
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: A
+
+---
+
+## E. Beveiligingsextensie (standaardvraag van de workflow)
+
+### Question 11
+Moeten de beveiligingsregels als harde vereisten worden afgedwongen voor dit project?
+
+A) Ja — dwing alle BEVEILIGINGSREGELS af als blokkerende vereisten (aanbevolen voor productietoepassingen)
+B) Nee — sla alle BEVEILIGINGSREGELS over (geschikt voor PoC's, prototypes en experimentele projecten)
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: A
+
+## F. Property-Based Testing-extensie (standaardvraag van de workflow)
+
+### Question 12
+Moeten de property-based testing (PBT) regels worden afgedwongen voor dit project?
+
+A) Ja — dwing alle PBT-regels af als blokkerende vereisten (aanbevolen voor projecten met bedrijfslogica, datatransformaties, serialisatie of stateful componenten)
+B) Gedeeltelijk — dwing PBT-regels alleen af voor pure functies en serialisatie round-trips (geschikt voor projecten met beperkte algoritmische complexiteit)
+C) Nee — sla alle PBT-regels over (geschikt voor eenvoudige CRUD-applicaties, UI-only projecten of dunne integratielagen zonder significante bedrijfslogica)
+X) Anders (beschrijf hieronder na de [Answer]:-tag)
+
+[Answer]: C
+
+## G. Operations-fase (standaardvraag van de workflow)
+
+### Question 13
+Moet deze feature na Construction ook door de Operations-fase (deployment- en monitoring-setup)?
+
+**Let op**: dit bepaalt alleen of de Operations-fase van déze feature draait — Question 7 hierboven bepaalt of die Operations-fase ook echt de CI/CD-pipeline omzet naar `Api.SlpSoftware`, of alleen bijvoorbeeld lokale/documentatie-stappen bevat.
+
+A) Ja — draai de Operations-fase na Construction
+B) Nee — stop na Build and Test (deployment/monitoring vallen buiten scope voor deze feature)
+C) Weet ik nog niet — vraag het me nogmaals na de Construction-fase
+X) Anders (beschrijf hieronder na de [Answer]:-tag)

+# Requirements Clarification Questions (Round 2) — SlpSoftware Production API
+
+Vul je keuze in achter de `[Answer]:`-tag. Kies de laatste optie (`Anders`) als niets past en geef dan zelf een naam op.
+
+---
+
+## Ambiguity 1: Modulenaam is bewust generieker bedoeld dan "Packages"
+
+Bij Question 9 in de vorige ronde koos je optie A (`SlpModularCms.Modules.Packages`), maar met de kanttekening dat die naam te specifiek/verwarrend aanvoelt: je wilt de module op termijn kunnen hergebruiken voor een heel ander soort klant/dienst (bijv. een fotograaf die fotoshoot-pakketten verkoopt), en "Packages" leest dan al snel als "software packages/library" in plaats van "dingen die een bedrijf aanbiedt op zijn marketingsite". Je vroeg om alternatieve suggesties.
+
+Kernidee van de module (los van de naam): een set **aanbiedingen/tiers met titel, beschrijving, prijs en features**, getoond op een marketingsite, per "tenant"/site herbruikbaar — dus geen SlpSoftware-specifieke naam, en geen naam die aanvoelt als een NuGet/library-package.
+
+### Clarification Question 1
+Welke naam past het best bij dit generieke, herbruikbare concept?
+
+A) `SlpModularCms.Modules.Offerings` — "wat een bedrijf aanbiedt" (product óf dienst), generiek en leest niet als software-package
+B) `SlpModularCms.Modules.ServiceCatalog` — benadrukt een catalogus van diensten/pakketten die getoond wordt
+C) `SlpModularCms.Modules.Pricing` — legt de nadruk op de prijstiers/pricing-cards zelf, minder op "wat" er verkocht wordt
+D) `SlpModularCms.Modules.Catalog` — maximaal generiek, bruikbaar voor vrijwel elk soort verkoopbaar item (niet alleen prijstiers)

+# Requirements — SlpSoftware Production API
+
+## Intent Analysis
+
+- **User Request**: Add a new deployable API in the `Clients` solution folder, `SlpModularCms.Api.SlpSoftware`, that will eventually replace `SlpModularCms.Api` as the API deployed to `test.slpsoftware.nl` / `slpsoftware.nl`. It hosts the existing Master module plus a new module covering what the SlpSoftware website needs, per the external hand-off doc `packages-api-handoff.md`.
+- **Request Type**: New Feature (new Client project + new module), with a CI/CD retarget as a downstream consequence.
+- **Scope Estimate**: Multiple Components — new Client project, shared hosting-pipeline extraction in `SlpModularCms.Core`, a new module + its test project, and (in the Operations phase) an extension of the existing deployment pipeline.
+- **Complexity Estimate**: Complex — touches solution structure, an in-flight Operations-phase feature's deploy pipeline (`gitea-deployment-workflow`), and a cross-workspace content contract owned by another repo's frontend.
+
+---
+
+## System Context
+
+- The `Clients` solution folder exists but is currently empty; `SlpModularCms.Api` and `SlpModularCms.Api.Slave` sit under `Application` today (per `CLAUDE.md` / `AGENTS.md`). `SlpModularCms.Api.SlpSoftware` will be the first project ever placed in `Clients`.
+- `SlpModularCms.Api` hosts four modules today: Core, Identity, Availability, Master (see `Program.cs` / module orchestrator), plus a composed hosting pipeline built during `gitea-deployment-workflow`: static content + SPA fallback for `/admin` and `wwwroot/web/`, health checks, security headers/CSP, rate limiting, Sentry, Data Protection, and startup migrations.
+- The external hand-off doc (`K:\Development\SlpSoftware\Projects\SlpSoftware\...\packages-api-handoff.md`, read-only reference) asks for a single public, unauthenticated `GET /api/v1/packages` backing the "Drie manieren om te starten" section of the website. The frontend already calls `fetch('/api/v1/packages')` with a relative, same-origin path.
+- That same reference workspace's `WEBSITE_WORKSPACE.md`, together with the (merged) `gitea-deployment-workflow` feature, establishes that in **this** repo the public site (`wwwroot/web/`) and the API are already served same-origin by one Client API process — so the hand-off doc's "add an nginx proxy_pass" open item does not apply here once `Api.SlpSoftware` is the deployed host (Q6 = A).
+- Roles available today (`HierarchicalRoleHandler`, `ServiceCollectionExtensions`): `Owner` (100) > `Administrator` (50) > `User` (10), with existing `OwnerOnly` / `AdminOnly` / `UserOnly` authorization policies.
+
+---
+
+## Decisions (traced to clarification questions)
+
+| # | Decision | Source |
+|---|---|---|
+| D-1 | `SlpModularCms.Api.SlpSoftware` is a new project in `Clients`; `SlpModularCms.Api` is unchanged and stays in `Application` as the dev host. | Q1 = A |
+| D-2 | `Api.SlpSoftware` hosts the same four modules as `Api` (Core, Identity, Availability, Master) plus the new module. | Q2 = A |
+| D-3 | The shared hosting/pipeline composition in `Program.cs` is extracted into a reusable method in `SlpModularCms.Core` (e.g. `CmsHost.Configure(...)`) so both Client `Program.cs` files stay thin and cannot drift apart. | Q3 = A |
+| D-4 | This feature includes admin CRUD (create/edit/delete/reorder) for the new content, not just the public read endpoint from the hand-off doc — that's the reason this becomes a CMS-managed module rather than staying hardcoded. | Q4 = B |
+| D-5 | No automatic seed migration for the three current packages. The user will enter content manually, but the **current live values must be preserved as documented reference data** so they aren't lost. Retrieved directly from the reference workspace's `content.ts` — see [Reference Content](#reference-content-not-auto-seeded) below. | Q5 = X (custom) |
+| D-6 | No nginx changes are needed for `/api/v1/` once `Api.SlpSoftware` is the deployed, same-origin host. | Q6 = A |
+| D-7 | Retargeting the CI/CD pipeline (`deploy-scp.yaml`, `continuous_integration.yaml`, `deployment-instructions.md` — currently owned by `gitea-deployment-workflow`) to `Api.SlpSoftware` is **in scope for this feature's Operations phase**, extending the existing pipeline rather than duplicating it. | Q7 = A |
+| D-8 | `SlpModularCms.Api` remains permanently as the local dev host, same role as `Api.Slave` today — no removal planned. | Q8 = A |
+| D-9 | The new module is named `SlpModularCms.Modules.Offerings` — deliberately domain-generic (not `Packages`, which reads as a software/library package, and not `SlpSoftware`-specific), since it must be reusable later for unrelated tenants/domains (the user's stated example: a photography business selling photoshoot packages). | Q9 = A (custom, follow-up round) |
+| D-10 | The module gets its own `DbContext` (e.g. `OfferingsDbContext`), consistent with the existing Availability/Master module-isolation pattern. | Q10 = A |
+| D-11 | The Security Baseline extension is **enabled and blocking** for this feature. | Q11 = A |
+| D-12 | The Property-Based Testing extension is **not enforced** for this feature. | Q12 = C |
+| D-13 | This feature runs the Operations phase after Construction. | Q13 = A |
+| D-14 | The public route is `/api/v1/offerings`, matching the module name, not `/api/v1/packages`. The corresponding frontend fetch-path change (`usePackagesQuery.ts`) in the external reference workspace is **out of scope for this feature** — the user will update it separately, on their own. | User feedback, post-Requirements-approval; confirmed via chat clarification (frontend update: "dat regel ik zelf") |
+| D-15 | The CI/CD pipeline retarget (FR-9) is a **cutover**: `SlpModularCms.Api` is replaced by `SlpModularCms.Api.SlpSoftware` as the pipeline's build/deploy target, not run side by side. | User feedback, post-Requirements-approval |

+
+## Functional Requirements
+
+### FR-1 — New Client Project: `SlpModularCms.Api.SlpSoftware`
+A new project `SlpModularCms.Api.SlpSoftware` is created under the `Clients` solution folder (first project ever placed there), per D-1. `SlpModularCms.Api` is not moved, renamed, or otherwise modified in role.
+
+### FR-2 — Module Composition
+`SlpModularCms.Api.SlpSoftware` references and hosts: `SlpModularCms.Core`, `SlpModularCms.Modules.Identity`, `SlpModularCms.Modules.Availability`, `SlpModularCms.Modules.Master`, and the new `SlpModularCms.Modules.Offerings` (D-2, D-9).
+
+### FR-3 — Shared Hosting Pipeline Extraction
+The composed hosting pipeline currently duplicated in `SlpModularCms.Api/Program.cs` (static content + SPA fallback for `/admin` and `wwwroot/web/`, health checks, security headers/CSP, rate limiting, Sentry, Data Protection, startup migrations, module orchestrator) is extracted into a reusable method in `SlpModularCms.Core` (e.g. `CmsHost.Configure(...)`). Both `SlpModularCms.Api/Program.cs` and `SlpModularCms.Api.SlpSoftware/Program.cs` call this shared method; project-specific differences (e.g. which modules are registered) remain explicit at each call site (D-3).
+
+### FR-4 — New Module: `SlpModularCms.Modules.Offerings`
+A new module `SlpModularCms.Modules.Offerings` is created following the existing `IModule` pattern, with its test project `SlpModularCms.Modules.Offerings.Tests` under `Tests/Modules` (per `CLAUDE.md` structure rules). The module owns an `Offering` entity and its own `OfferingsDbContext` + migrations, isolated from other modules' schemas (D-9, D-10).
+
+### FR-5 — `Offering` Entity
+The `Offering` entity carries the fields required by the public API contract (see FR-6) and by admin management (FR-7): a stable slug-like `Id`, `Title`, `Description`, `Price` (pre-formatted display string, not a number — e.g. `"€ 300"` or `"Op maat"`), `PriceNote`, an ordered list of `Features` (plain text), `CtaLabel`, a `Featured` flag, and an explicit `DisplayOrder` (or equivalent ordering field) so admin reordering (FR-7) has something durable to persist, independent of the public array's rendered order.
+
+### FR-6 — Public Endpoint: `GET /api/v1/offerings`
+A public, unauthenticated `GET /api/v1/offerings` endpoint returns a JSON array of offerings in display order, matching the field contract from the hand-off doc:
+
+```json
+[
+  {
+    "id": "pakket_01",
+    "title": "Landingspagina",
+    "description": "Eén overtuigende pagina die je product of dienst helder neerzet.",
+    "price": "€ 300",
+    "priceNote": "eenmalig, excl. btw",
+    "features": ["Eén pagina in HTML & CSS", "..."],
+    "ctaLabel": "Kies landingspagina",
+    "featured": false
+  }
+]
+```
+
+**Note on the frontend dependency**: the frontend in the external, read-only reference workspace currently fetches the old path (`fetch('/api/v1/packages')`). Changing the route to `/api/v1/offerings` (D-14) means that fetch call needs to change too — the user has confirmed this is **out of scope for this feature**; they will update it separately in that workspace. Until that frontend change happens, the website's package section will show its error state against a deployed `Api.SlpSoftware`, same as today against no backend at all.
+
+### FR-7 — Admin CRUD for Offerings
+The admin SPA (served under `/admin` by the same Client API, per the existing hosting pipeline) gets management screens to create, edit, delete, and reorder offerings, backed by authenticated API endpoints (`POST` / `PUT` / `DELETE` / a reorder operation on `/api/admin/offerings` or equivalent). These endpoints require the existing `AdminOnly` authorization policy (`Administrator` role or higher), consistent with other content-management operations in this system (D-4).
+
+### FR-8 — Reference Content (Not Auto-Seeded)
+
+<a id="reference-content-not-auto-seeded"></a>
+
+No database seed migration is created (D-5). Instead, the three packages currently live on the website are captured here as the reference values the user will enter manually through the new admin CRUD (FR-7), retrieved from the external reference workspace's `content.ts`:
+
+| `id` | `title` | `description` | `price` | `priceNote` | `features` | `ctaLabel` | `featured` |
+|---|---|---|---|---|---|---|---|
+| `pakket_01` | Landingspagina | Eén overtuigende pagina die je product of dienst helder neerzet. | € 300 | eenmalig, excl. btw | Eén pagina in HTML & CSS; Ontwerp op maat, geen template; Responsive op elk scherm; Snelle laadtijd & SEO-basis | Kies landingspagina | false |
+| `pakket_02` | Website | Een complete website met meerdere pagina's, klaar om te groeien. | € 750 | eenmalig, excl. btw | Drie pagina's in HTML & CSS; Extra pagina's als optie bij te bestellen; Consistente huisstijl over alle pagina's; Responsive, snel & SEO-basis | Kies website | true |
+| `pakket_03` | Maatwerk | Grotere websites, een eigen back-end of andere .NET-projecten. | Op maat | offerte na intake | Grotere websites & webapplicaties; Losse back-end in .NET / C#; Koppelingen & API's; Advies over de beste aanpak | Vraag offerte aan | false |
+
+Per the hand-off doc's business rule BR-4 (content fidelity), these values must be reproduced exactly, not paraphrased, if/when entered.
+
+### FR-9 — CI/CD Retarget (Operations Phase)
+The existing Gitea Actions pipeline (`continuous_integration.yaml`, `deploy-scp.yaml`) and `deployment-instructions.md` — currently targeting `SlpModularCms.Api`, owned by the `gitea-deployment-workflow` feature — is extended (not duplicated) to build, test, and deploy `SlpModularCms.Api.SlpSoftware` as the artifact shipped to `test.slpsoftware.nl` / `slpsoftware.nl`. This is executed in this feature's Operations phase, coordinated with `gitea-deployment-workflow` rather than forking its pipeline (D-7). Per D-15, this is a **cutover**: the pipeline's build/deploy target switches from `SlpModularCms.Api` to `SlpModularCms.Api.SlpSoftware` — it does not build and deploy both APIs side by side.
+
+---
+
+## Non-Functional Requirements
+
+### NFR-1 — No Nginx Changes Required
+No nginx `location /api/v1/` proxy is added. `Api.SlpSoftware` serves the site, `/admin`, and `/api/v1` same-origin from one process, matching the existing `Api` hosting model (D-6).
+
+### NFR-2 — Module Test Coverage
+`SlpModularCms.Modules.Offerings` follows this project's existing test coverage standard for new modules, with unit tests for the `Offering` entity, `OfferingsDbContext`, the public read endpoint, and the admin CRUD endpoints (including authorization checks).
+
+### NFR-3 — Long-Term Reusability of the Offerings Module
+The module's naming, entity design, and any tenant/site-scoping must not bake in SlpSoftware-specific assumptions (e.g. hardcoded copy, hardcoded routes beyond the one fixed contract in FR-6), since the user's stated intent is to reuse this module for unrelated future sites/domains (D-9).
+
+### NFR-4 — Property-Based Testing Not Required
+No PBT tooling or rules are introduced for this feature's tests (D-12).
+
+---
+
+## Security Compliance (Security Baseline extension — enabled, blocking)
+
+| Rule | Status | Notes |
+|---|---|---|
+| SECURITY-01 Encryption at rest/transit | **Pre-existing, unchanged** | `OfferingsDbContext` uses the same MariaDB connection (TLS-enforced) as Availability/Master; no new data store technology introduced. |
+| SECURITY-02 Access logging on intermediaries | **N/A** | No load balancer, API gateway, or CDN in this architecture — the application itself is the only network-facing component. |
+| SECURITY-03 Application-level logging | **Pre-existing, unchanged** | Reuses the shared logging/Sentry setup extracted in FR-3. |
+| SECURITY-04 HTTP security headers | **Pre-existing, unchanged** | Reuses the shared security-headers middleware extracted in FR-3; applies identically on `Api.SlpSoftware`. |
+| SECURITY-05 Input validation | **Addressed** | Admin CRUD endpoints (FR-7) validate all `Offering` fields (type, length bounds on `Title`/`Description`/`Price`/`PriceNote`/`CtaLabel`, array bounds on `Features`) and use EF Core parameterized queries. |
+| SECURITY-06 Least-privilege access policies | **Addressed** | Admin endpoints use the existing `AdminOnly` policy, not `OwnerOnly` or an ad-hoc broader policy (FR-7). |
+| SECURITY-07 Restrictive network configuration | **N/A** | No cloud networking/firewall resources introduced by this feature. |
+| SECURITY-08 Application-level access control | **Addressed** | The public `GET /api/v1/offerings` (FR-6) is deliberately and explicitly anonymous, matching the hand-off doc's requirement; all mutation endpoints (FR-7) require authentication and the `AdminOnly` policy, following deny-by-default. |
+| SECURITY-09 Hardening and misconfiguration | **Pre-existing, unchanged** | Reuses the shared pipeline's existing error handling (`GlobalExceptionHandler`) and Development-only OpenAPI/Scalar exposure. |
+| SECURITY-10 Supply chain | **Pre-existing, unchanged** | New module adds no new third-party dependencies beyond what the solution already uses (EF Core, ASP.NET Core); covered by the existing blocking vulnerability gate from `gitea-deployment-workflow`. |
+| SECURITY-11 Secure design | **Addressed** | Admin (security-critical) operations are isolated behind `AdminOnly`, distinct from the public read path; rate limiting is inherited from the shared pipeline (FR-3) and therefore also applies to the new public endpoint. |
+| SECURITY-12 Authentication and credentials | **Pre-existing, unchanged** | Reuses the existing Identity module; no new credential handling introduced. |
+| SECURITY-13 Software and data integrity | **Addressed** | Admin mutations to `Offering` records should be auditable at the same level as other content mutations in this system (who/when) — tracked as an open item (see below) if no existing audit mechanism covers module-level content changes. |
+| SECURITY-14 Alerting and monitoring | **Pre-existing, unchanged** | Reuses the shared Sentry-based alerting from `gitea-deployment-workflow`; no new alert categories introduced by this feature. |
+| SECURITY-15 Exception handling and fail-safe defaults | **Pre-existing, unchanged** | Reuses the shared `GlobalExceptionHandler`; new endpoints follow the same fail-closed pattern (auth failure → 401/403, not silent fallback). |
+
+**Open item**: SECURITY-13 audit-trail coverage for `Offering` create/edit/delete/reorder is not yet confirmed against an existing system-wide audit mechanism (or its absence) — to be resolved at Functional Design / NFR Design for the Offerings unit, not blocking Requirements sign-off.
+
+---
+
+## Scope Boundaries
+
+| In Scope | Out of Scope |
+|---|---|
+| New `SlpModularCms.Api.SlpSoftware` project in `Clients` | Moving/renaming `SlpModularCms.Api` |
+| Shared `CmsHost.Configure(...)`-style extraction in `SlpModularCms.Core` | Removing or deprecating `SlpModularCms.Api` |
+| New `SlpModularCms.Modules.Offerings` module + `SlpModularCms.Modules.Offerings.Tests` | Multi-tenant/site-scoping infrastructure for reuse by a future, unrelated site (only the *naming/design* must not preclude it — D-9, NFR-3) |
+| `Offering` entity + `OfferingsDbContext` + migrations | Automatic data seeding of the three current packages (D-5) |
+| Public `GET /api/v1/offerings` (unauthenticated) | nginx configuration changes (D-6) |
+| Admin CRUD (create/edit/delete/reorder) for offerings, `AdminOnly`-protected | Frontend changes in the external `SlpSoftware` reference workspace, **including** updating `usePackagesQuery.ts`'s fetch path to `/api/v1/offerings` (D-14 — user's own follow-up) |
+| CI/CD retarget of the existing pipeline to `Api.SlpSoftware` as a **cutover** (Operations phase, D-15) | Running `Api` and `Api.SlpSoftware` pipelines side by side |
+| Documenting the current live package copy as reference content (FR-8) | Entering that content into the running system (the user will do this manually) |
+
+---
+
+## Assumptions
+
+| # | Assumption | Risk if wrong |
+|---|---|---|
+| ~~A-1~~ | ~~The public route stays `/api/v1/packages` even though the module is `Offerings`.~~ **Resolved 2026-08-01**: route is `/api/v1/offerings` (D-14); frontend update is the user's own, separate follow-up. | Closed |
+| A-2 | Admin CRUD for offerings requires `AdminOnly` (Administrator role), not `OwnerOnly`. | Low-medium — if the user wants offering management restricted to Owner only, this is a one-line policy change, best confirmed at Application Design. |
+
+---
+
+**9 functional requirements, 4 non-functional requirements, 15 traced decisions, 1 open assumption (1 resolved), 1 open item (security audit-trail coverage).**

+# Personas — SlpSoftware Production API
+
+## Persona 1: Site Visitor
+
+| Attribute | Description |
+|---|---|
+| **Role** | Anonymous visitor of the public website (`test.slpsoftware.nl` / `slpsoftware.nl`) |
+| **Access Level** | None — unauthenticated, public |
+| **Goal** | Understand what services/packages are on offer, their price and what's included, so they can decide which one fits their needs and get in touch. |
+| **Pain Points** | A broken or empty "Drie manieren om te starten" section erodes trust before the visitor even reaches the contact form. |
+| **Technical Context** | Interacts only through the existing React frontend (external, read-only reference workspace) — never calls the API directly. All API behavior is experienced indirectly through what the frontend renders. |
+| **Relationship to this feature** | Consumes `GET /api/v1/offerings` (FR-6) indirectly. Never touches the admin CRUD (FR-7). |
+
+## Persona 2: CMS Administrator
+
+| Attribute | Description |
+|---|---|
+| **Role** | Authenticated user holding the `Administrator` role (or higher — `Owner`, per the existing role hierarchy) |
+| **Access Level** | `AdminOnly` policy — full CRUD access to offerings via the admin SPA under `/admin` |
+| **Goal** | Keep the list of offerings shown on the website accurate and up to date (pricing, features, copy) without needing a code deploy, and control which one is highlighted as "most chosen". |
+| **Pain Points** | Today this content is hardcoded in the frontend's `content.ts` — any change requires a frontend deploy. This feature removes that dependency. |
+| **Technical Context** | Uses the existing admin SPA (already served under `/admin` by the same Client API, per the shared hosting pipeline). Not a developer — needs a UI, not direct API/database access. |
+| **UI Language Note** | The existing admin SPA already ships with `nl`/`en` i18n locales (`frontend/src/i18n/locales/`), where the `Administrator` role is already labeled `"Beheerder"` in Dutch. This persona's documentation name ("CMS Administrator") is the English documentation term; the on-screen label the persona actually sees follows the existing i18n setup and needs no new translation work. |
+| **Relationship to this feature** | Sole user of the new admin CRUD (FR-7): create, edit, delete, reorder offerings, and control the `featured` flag. |

+# User Stories — SlpSoftware Production API
+
+Breakdown approach: **persona-based** (approved). Acceptance criteria format: **Given/When/Then** (approved).
+
+---
+
+## Epic A — Site Visitor: Viewing Offerings
+
+### US-01 — View the list of available offerings
+**As a** Site Visitor, **I want** to see the current list of offerings on the website, **so that** I can compare what's available and pick one that fits my needs.
+
+**Acceptance Criteria**
+- **Given** one or more offerings exist in the CMS, **when** the frontend requests `GET /api/v1/offerings`, **then** the response is `200 OK` with a JSON array of offerings in display order, each including `id`, `title`, `description`, `price`, `priceNote`, `features`, `ctaLabel`, and `featured`.
+- **Given** the offerings are returned, **when** rendered, **then** the array order is the same order the CMS Administrator configured (FR-5 `DisplayOrder`) — no re-sorting happens client-side or server-side beyond that stored order.
+
+**Traceability**: FR-5, FR-6
+
+---
+
+### US-02 — See the recommended offering highlighted
+**As a** Site Visitor, **I want** to see which offering is the "most chosen" one, **so that** I have a quick recommendation if I'm unsure which package to pick.
+
+**Acceptance Criteria**
+- **Given** the CMS Administrator has marked exactly one offering as featured, **when** `GET /api/v1/offerings` is called, **then** exactly one item in the response has `"featured": true` and all others have `"featured": false`.
+- **Given** no offering has been explicitly marked as featured, **when** `GET /api/v1/offerings` is called, **then** every item has `"featured": false` (no forced default featured item).
+
+**Traceability**: FR-5, FR-6; enforcement mechanism defined in US-10
+
+---
+
+### US-03 — Website stays functional with zero offerings
+**As a** Site Visitor, **I want** the site to still work correctly even if no offerings have been configured yet, **so that** I don't encounter a broken page during initial setup or content maintenance.
+
+**Acceptance Criteria**
+- **Given** zero offerings exist in the CMS, **when** the frontend requests `GET /api/v1/offerings`, **then** the response is `200 OK` with an empty JSON array `[]` — not an error response.
+- **Given** this empty-array response, **then** it is the frontend's responsibility (out of scope for this feature) to decide how to render an empty state; the API's only obligation is a valid, non-error response.
+
+**Traceability**: FR-6; decision Q4 = A (allow empty list, no deletion guard)
+
+---
+
+## Epic B — CMS Administrator: Managing Offerings
+
+### US-04 — Create a new offering
+**As a** CMS Administrator, **I want** to create a new offering with title, description, price, price note, features, and CTA label, **so that** I can add a new package/service to the website without a code deploy.
+
+**Acceptance Criteria**
+- **Given** I am authenticated with at least the `Administrator` role, **when** I submit a new offering with all required fields (`Title`, `Description`, `Price`, `PriceNote`, at least one `Feature`, `CtaLabel`), **then** the offering is persisted and immediately appears in `GET /api/v1/offerings` at the end of the display order.
+- **Given** I create an offering without marking it featured, **when** it is saved, **then** `featured` defaults to `false`.
+
+**Traceability**: FR-5, FR-7
+
+---
+
+### US-05 — Edit an existing offering
+**As a** CMS Administrator, **I want** to edit an existing offering's content, **so that** I can correct or update pricing and copy as the business changes.
+
+**Acceptance Criteria**
+- **Given** an existing offering, **when** I update any of its fields and save, **then** `GET /api/v1/offerings` reflects the new values on the next request.
+- **Given** I edit an offering, **when** I save it, **then** its `id` (stable slug) and `DisplayOrder` are not changed as a side effect of the edit — only reordering (US-08/US-09) changes order.
+
+**Traceability**: FR-5, FR-7
+
+---
+
+### US-06 — Delete an offering
+**As a** CMS Administrator, **I want** to delete an offering that's no longer relevant, **so that** the website doesn't show outdated packages.
+
+**Acceptance Criteria**
+- **Given** more than one offering exists, **when** I delete one of them, **then** it no longer appears in `GET /api/v1/offerings`, and the remaining offerings keep their relative display order.
+
+**Traceability**: FR-7
+
+---
+
+### US-07 — Delete the last remaining offering
+**As a** CMS Administrator, **I want** to be able to delete the last remaining offering if needed, **so that** I'm not blocked from clearing content during a redesign or content pause, even though it temporarily leaves the site with nothing to show.
+
+**Acceptance Criteria**
+- **Given** exactly one offering exists, **when** I delete it, **then** the deletion succeeds (no blocking validation error) and `GET /api/v1/offerings` subsequently returns `[]`.
+
+**Traceability**: FR-7; decision Q4 = A (deletion is never blocked to prevent an empty list)
+
+---
+
+### US-08 — Reorder offerings via drag-and-drop
+**As a** CMS Administrator, **I want** to reorder offerings by dragging them into a new position in the list, **so that** I can control the order visitors see them in without editing a numeric field.
+
+**Acceptance Criteria**
+- **Given** two or more offerings, **when** I drag one to a new position and the change is saved, **then** the `DisplayOrder` values are updated so `GET /api/v1/offerings` reflects the new order.
+
+**Traceability**: FR-5, FR-7; decision Q5 = A+B
+
+---
+
+### US-09 — Reorder offerings via up/down buttons
+**As a** CMS Administrator, **I want** an alternative to drag-and-drop — explicit "move up" / "move down" controls per row, **so that** I can reorder offerings accurately even without a mouse, or when drag-and-drop is impractical (accessibility, precision).
+
+**Acceptance Criteria**
+- **Given** an offering that is not first in the list, **when** I use its "move up" control, **then** it swaps display order with the offering immediately before it.
+- **Given** an offering that is not last in the list, **when** I use its "move down" control, **then** it swaps display order with the offering immediately after it.
+- **Given** the first offering in the list, **then** its "move up" control is disabled (and symmetrically for "move down" on the last offering).
+
+**Traceability**: FR-5, FR-7; decision Q5 = A+B (accessible fallback alongside drag-and-drop)
+
+---
+
+### US-10 — Mark an offering as featured (system-enforced exclusivity)
+**As a** CMS Administrator, **I want** the system to guarantee that at most one offering is marked "featured" at any time, **so that** I don't accidentally end up with a confusing website showing more than one "most chosen" badge (per the external hand-off doc's expectation, which the frontend itself does not enforce).
+
+**Acceptance Criteria**
+- **Given** offering A is currently featured, **when** I mark offering B as featured, **then** offering A is automatically un-featured in the same operation — the system never persists more than one featured offering at a time.
+- **Given** no offering is currently featured, **when** I mark one as featured, **then** exactly that one becomes featured.
+- **Given** the currently featured offering, **when** I explicitly un-feature it (without featuring another), **then** zero offerings are featured — this is a valid state (see US-02).
+
+**Traceability**: FR-5, FR-7; decision Q3 = A
+
+---
+
+### US-11 — Receive validation feedback on invalid input
+**As a** CMS Administrator, **I want** clear validation errors when I submit incomplete or malformed offering data, **so that** I can fix my mistake instead of silently corrupting the website's content.
+
+**Acceptance Criteria**
+- **Given** I submit an offering missing a required field (`Title`, `Description`, `Price`, `PriceNote`, `CtaLabel`, or `Features`), **when** I save, **then** the request is rejected with a validation error identifying which field(s) are invalid, and no partial record is persisted.
+- **Given** I submit a field exceeding its defined maximum length, **when** I save, **then** the request is rejected the same way.
+
+**Traceability**: FR-7; SECURITY-05 (Input Validation)
+
+---
+
+### US-12 — Admin actions require the Administrator role
+**As a** CMS Administrator, **I want** offering management to be inaccessible to anyone without at least the `Administrator` role, **so that** unauthenticated visitors or lower-privileged users can't alter the website's content.
+
+**Acceptance Criteria**
+- **Given** an unauthenticated request, **when** it targets any admin offerings endpoint (create/edit/delete/reorder), **then** it is rejected with `401 Unauthorized`.
+- **Given** an authenticated request from a `User`-role account (below `Administrator` in the hierarchy), **when** it targets any admin offerings endpoint, **then** it is rejected with `403 Forbidden`.
+- **Given** an authenticated request from an `Administrator`- or `Owner`-role account, **when** it targets any admin offerings endpoint, **then** it is permitted (subject to the other acceptance criteria above).
+
+**Traceability**: FR-7; SECURITY-06, SECURITY-08
