+# Feature Specification: Administration Case Studies and Public Reads
+
+**Feature Branch**: `005-admin-case-studies`
+
+**Created**: 2026-08-19
+
+**Status**: Draft
+
+**Input**: Staff Administration CRUD for case studies, industries, and case study categories; plus unauthenticated public read endpoints for published case studies.
+
+**Constitution alignment**: Contract-first (III), security (VIII), i18n (V), quality gates (XIII). Public SEO (I) is a non-regression: drafts MUST NOT appear on public routes.
+
+## Scope
+
+This feature **adds** staff management of case studies (with industries, case study categories, and technologies) on the Administration UI, and **adds** a separate public read API for published case studies.
+
+Row `draft` / `publish` is stored on each entity. It does **not** use the site-settings/page publish snapshot pipeline.
+
+### In scope
+
+- Administration list, create, edit, and delete of case studies, industries, case study categories, and technologies
+- Search and pagination of ten on every admin list
+- Case study, industry, category, and technology status `draft` or `publish`
+- Many-to-many industries, case study categories, and technologies on a case study
+- Public, unauthenticated `GET` list of published case studies
+- Public, unauthenticated `GET` of one published case study by slug
+- Public, unauthenticated `GET` list of published technologies
+- Separate admin and public contracts, schemas, and routes
+
+### Out of scope
+
+- Public write, update, delete, or publish actions
+- Public counterparts for auth, RBAC, snapshot publish, or media upload
+- Website frontend case study pages
+- New RBAC permission names
+
+## User Scenarios & Testing
+
+### User Story 1 - Staff manage case studies (Priority: P1)
+
+A signed-in staff member lists case studies (search, ten per page) and creates or updates heading, slug, short heading, description, order, industries, categories, technologies, image, body, date, and publish state.
+
+**Acceptance Scenarios**:
+
+1. **Given** an unauthenticated caller, **When** they request `/admin/case-studies`, **Then** the request is rejected
+2. **Given** staff with view permission, **When** they list case studies, **Then** they see drafts and published rows with search and pagination of ten
+3. **Given** staff with draft-save permission, **When** they create or update a case study, **Then** the stored row matches the submitted fields including status
+
+### User Story 2 - Staff manage industries and categories (Priority: P1)
+
+Staff create industries, case study categories, and technologies by name. Technologies also store a logo. Default state is draft. Publish sets state to published. Created published technologies appear in the case study multi-select. Only published technologies may be assigned to a case study.
+
+### User Story 3 - Public published case studies (Priority: P1)
+
+Unauthenticated callers list and fetch published case studies by slug. Drafts are absent from the list; draft slugs return the same 404 as unknown slugs.
+
+## Requirements
+
+- **FR-001**: Staff with records.view MUST list and read case studies, industries, case study categories, and technologies on `/api/v1/admin/...`.
+- **FR-002**: Staff with drafts.save MUST create, update, and delete those entities on `/api/v1/admin/...`.
+- **FR-003**: Unauthenticated or under-privileged admin requests MUST be rejected (401 or 403).
+- **FR-004**: Status MUST be stored on each row as `draft` or `publish` and MUST NOT write the snapshot pipeline.
+- **FR-005**: Versioned admin contract `contracts/admin-case-studies.v1.yaml` is the staff boundary.
+- **FR-006**: Unauthenticated `GET /api/v1/public/case-studies` returns only `publish` case studies (`q`, `page`, `per_page` max 10).
+- **FR-007**: Unauthenticated `GET /api/v1/public/case-studies/{slug}` returns one published case study. Draft or unknown slugs return 404 `public.case_studies.not_found`.
+- **FR-008**: Public list and detail use separate schemas and routes from admin. Public detail is identified by slug.
+- **FR-009**: Public nested industries and categories include only published related names. Public nested technologies include only published related names and `logo_key`. Public payloads omit `state`, `status`, UUIDs, and relation IDs.
+- **FR-010**: `contracts/public-case-studies.v1.yaml` MUST NOT be generated into the Administration FE client.
+- **FR-011**: Unauthenticated `GET /api/v1/public/technologies` returns only `publish` technologies with name and `logo_key`.
+- **FR-012**: Case study technology assignment MUST accept only published technologies.
+
+## Key Entities
+
+- **CaseStudy**: Heading, unique slug, short heading, description, order, date, body, image, status, industries, categories, technologies.
+- **Industry**: Named grouping with status, many-to-many with case studies.
+- **CaseStudyCategory**: Named grouping with status and related case study count.
+- **Technology**: Named grouping with optional logo, status, many-to-many with case studies.
