Title: requireTitle() turns the VARCHAR(255) DB bound into a friendly 400 (GESCHICHTE_TITLE_TOO_LONG). JOURNEY intro: MAX_INTRO_LENGTH = 4000 in bodyForType() plus a V75 CHECK as atomic backstop (defensive clamp first, STORY bodies exempt) — GESCHICHTE_INTRO_TOO_LONG. Both codes wired through ErrorCode.java, errors.ts, getErrorMessage and de/en/es. DB-layer boundary pins added: exactly-2000 note insert (V74 CHECK) and 4000/4001 intro inserts against real Postgres. Docs: error-code lists, db puml diagrams. The matching maxlength attributes land with the component commits. Review round 3: Markus (b), Nora (1), Sara (DB 2000 boundary).

docs/
Project documentation organised into four categories: architecture decision records (ADRs), system architecture diagrams, infrastructure runbooks, and detailed UI/UX specifications.

ADR (adr/)
Architecture Decision Records capture major technical decisions and their rationale.
| ADR | Title | Status |
|---|---|---|
001-ocr-python-microservice.md |
OCR as a separate Python container | Accepted |
002-polygon-jsonb-storage.md |
Polygon coordinates in JSONB columns | Accepted |
003-chronik-unified-activity-feed.md |
Unified activity feed (Chronik) | Accepted |
When making a significant architectural change (new service, data model change, technology swap), write a new ADR:
- Status (Proposed / Accepted / Deprecated / Superseded)
- Context (forces at play)
- Decision (what we decided)
- Consequences (trade-offs)
- Alternatives Considered (table format)
ADRs are sequential (NNN-descriptive-name.md). Do not reuse numbers.
Architecture (architecture/)
Contains C4 model diagrams describing the system at different zoom levels:
- Context diagram — How Familienarchiv fits into the user and system ecosystem
- Container diagram — The high-level technology choices (Spring Boot, SvelteKit, PostgreSQL, MinIO, OCR service)
- Component diagram — Major structural components within the backend
Written in Markdown with embedded Mermaid diagrams (c4-diagrams.md). Gitea renders these automatically.
For the human-readable architecture narrative, see docs/ARCHITECTURE.md.
Infrastructure (infrastructure/)
Operational documentation for running Familienarchiv in production and CI.
| Document | Purpose |
|---|---|
ci-gitea.md |
Gitea CI/CD pipeline configuration |
production-compose.md |
Production Docker Compose setup and VPS provisioning |
s3-migration.md |
Migrating documents between S3 buckets |
self-hosted-catalogue.md |
Self-hosted software catalogue |
For the day-1 deployment checklist, see docs/DEPLOYMENT.md.
Specs (specs/)
High-fidelity UI/UX specifications written as standalone HTML files. These are design documents describing exact layout, interactions, and responsive behavior before implementation.
Each spec typically includes:
- Visual mockups with CSS-in-HTML styling
- Interaction flows and state transitions
- Responsive breakpoint behavior
- Accessibility requirements
Before implementing a feature, check specs/ for an existing specification.
Style Guide
docs/STYLEGUIDE.md covers:
- Code formatting and linting rules
- Component naming conventions
- Color palette and typography
- Accessibility standards (WCAG 2.1 AA)
