CI / web (push) Has been cancelled
docs: consolidate frontend guardrails + test-harness gotchas
Adds web/GUARDRAILS.md capturing the recurring CI-guardrail and
test-harness lessons in one place: the check:size (250 KB-gz largest
chunk) and check:colors (design-token) guards, the jsdom/storybook
vitest split, MSW onUnhandledRequest:"error" overrides, RTL
accessible-name collisions, Storybook nested-router/portal handling,
and the components/ui code-style split. Wires a pointer from CLAUDE.md.

All claims verified against the live scripts, ci.yaml, and src/test/.

# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Status
Rust (edition 2024) workspace + React SPA collection-management system. Backend crates: `domain`, `db`, `api`, `auth`, `search`, `server` (axum 0.8 + sqlx/Postgres + Meilisearch). Frontend in `web/` (React 19 + Vite + pnpm). Tests need the docker-compose stack up (Postgres on **:5442**, Meilisearch on **:7700**); each `#[sqlx::test]` provisions its own temp DB.
## Commands
```bash
just check # fmt + lint + test — the standard pre-commit gate
docker compose up -d # start Postgres (:5442) + Meilisearch (:7700) for tests
cargo build --workspace # build
cargo run -p server # run the server (or: just run — loads .env)
cargo nextest run --workspace # run all tests — PREFERRED (per-test isolation, live output, hang timeouts)
cargo nextest run -E 'test(<name>)' # run tests matching a name substring
cargo test --workspace --doc # doctests (nextest does not run these)
cargo +nightly fmt # format — always nightly, not stable
cargo clippy --workspace --all-targets -- -D warnings # lint before committing
```
(`just test` runs nextest + doctests; config in `.config/nextest.toml`.)
## Conventions
- **CLI args & env vars:** use `clap` with the `derive` feature.
- **Code navigation:** prefer the insikt LSP server over grep/glob — it resolves macro-generated symbols that text search misses. (insikt runs standalone, not via the gateway MCP.)
- **Dependencies:** manage via the `cargo-mcp` server rather than editing `Cargo.toml` by hand.
- **Formatting:** `cargo +nightly fmt` (nightly toolchain required).
- **Frontend guardrails:** before touching `web/`, read **[web/GUARDRAILS.md](web/GUARDRAILS.md)** — it covers the CI gate (`check:size` 250 KB-gz budget, `check:colors` design-token enforcement) and the test-harness quirks (MSW `onUnhandledRequest: "error"`, the jsdom/storybook vitest split, RTL accessible-name collisions, Storybook nested-router and portal handling, and the `components/ui/` code-style split).
