API Contract Change End To End

Goal

Make API changes once, but keep all consumers consistent (CLI/server, UI, docs).

Checklist

1. Locate the endpoint

• Routing/handlers: src/routes.rs, src/api_server.rs, src/web_server.rs

2. Update Rust contract types

• DTOs: src/api_types.rs
• If you adjust validation/errors, keep behavior consistent with existing API error shapes (src/errors.rs).

3. Update UI types + API client

• DTOs: view/api/types.ts (explicit note at top: aligned with src/api_types.rs)
• Calls: view/api/client.ts

4. Update OpenAPI + help docs

• REST schema: docs/openapi.json
• If it’s user-visible, update relevant guides under docs/help/* (often docs/help/api-quick-reference.md, plus the feature-specific page).

5. Add/adjust tests

• Rust behavior: tests/*.rs (integration-heavy, many use assert_cmd).
• UI behavior: npm run test:ui (Vitest).
• Cross-cutting behavior: consider adding/updating smoke coverage under smoke/tests/.

6. Verify locally (CI parity)

• npm run lint
• npm test
• npm run smoke

Notes

• Treat this repo as “contract-synchronized”: changing just one of Rust/UI/OpenAPI will likely break users or tests.
• Prefer incremental changes that preserve backwards compatibility for existing clients when practical.
