# Tasks: enterprise-server-linter

**Change ID**: enterprise-server-linter
**Package**: `@suaveplan/linter`
**Target path**: `server/infra/linter`
**Prerequisites on Verdaccio**: `@suaveplan/error`, `@suaveplan/types`, `@suaveplan/logger`

## 0. Pre-flight (non-negotiable)

- [ ] 0.1 Confirm clean working tree (`git status` reports nothing) and no in-flight worktrees with uncommitted work (`git worktree list` then `git status` in each)
- [ ] 0.2 If any worktrees exist under `.claude/worktrees/`, account for each one: still-active agent, work-pending-merge, or stale-and-prune. Stale worktrees MUST be removed (`git worktree remove`) before opening a new one — code that has been lost twice on main is the failure mode this guards against.
- [ ] 0.3 Confirm the package set in `MANIFEST.md` matches `find packages -maxdepth 3 -name package.json` count. Drift here means a prior change archived without regenerating the manifest.

## 1. Scaffold

- [ ] Create directory tree per `proposal.md`.
- [ ] `package.json` at `0.1.0`, `"sideEffects": false`, exports:
  - `"."`: main barrel
  - `"./presets/base"`: `"./presets/base.json"`
  - `"./presets/library"`: `"./presets/library.json"`
  - `"./presets/react"`: `"./presets/react.json"`
  - `"./presets/node"`: `"./presets/node.json"`
  - `"./presets/test"`: `"./presets/test.json"`
  - `"./runner"`: runner subpath
- [ ] Deps: `@suaveplan/error workspace:^`, `@suaveplan/types workspace:^`, `@suaveplan/logger workspace:^`, `zod catalog:forms`, `@opentelemetry/api catalog:observability`, `@biomejs/biome catalog:build`, `tslib catalog:build`.
- [ ] DevDeps: `vitest catalog:testing`, `@vitest/coverage-istanbul catalog:testing`, `@suaveplan/testing workspace:^`.
- [ ] `tsconfig.json` extending `library-node.json`; `vitest.config.ts` with `createTestConfig()`.
- [ ] Scripts: `lint`, `typecheck`, `test`, `test:coverage`, `build`, `docs:check`.

## 2. Preset JSON files

- [ ] Write `presets/base.json`: Biome config extending Biome recommended; enables linter rules for correctness, complexity, suspicious; format with tabs, double quotes, trailing commas; max line width 120.
- [ ] Write `presets/library.json`: extends base; stricter TypeScript rules (no explicit any, no unsafe member access), required return types.
- [ ] Write `presets/react.json`: extends library; enables JSX rules; allows JSX a11y overrides.
- [ ] Write `presets/node.json`: extends library; allows Node.js `process`, globals.
- [ ] Write `presets/test.json`: extends base; relaxes return-type and explicit-any rules inside test files; allows `describe`/`it`/`expect` globals.

## 3. Types and errors

- [ ] Define `LinterOptions`, `LintResult`, `LintDiagnostic` and Zod schemas in `src/types/linter.types.ts`.
- [ ] Write `linter.types.md` (≥200 words, both examples, API reference).
- [ ] `src/error-codes.ts`: three codes; `registerLinterErrorCodes()`; eager call.

## 4. Linter runner

- [ ] Implement `LinterRunner` in `src/runner/linter-runner/linter-runner.ts`:
  - Spawn Biome CLI via `Bun.spawn(['biome', 'check', '--reporter=json', ...targets])` with configPath arg when provided.
  - Parse JSON output into `LintResult`. Map Biome diagnostic fields to `LintDiagnostic`.
  - `check(targets)`: `biome check` — returns diagnostics without fixing.
  - `fix(targets)`: `biome check --apply` — applies safe fixes.
  - `format(targets)`: `biome format --write` — formats files.
  - Non-zero exit code with no JSON output: throw `LINTER_EXECUTION_FAILED`.
  - OTel counter `linter.runs_total` with `command` and `passed`; histogram `linter.duration_ms`.
- [ ] Write `linter-runner.types.ts`.
- [ ] Write `linter-runner.test.ts` (≤500 lines): check passes on valid TS file; check fails on file with intentional error; fix resolves auto-fixable issues; invalid target throws `LINTER_INVALID_TARGET`. Use real temp file with known content.
- [ ] Write `linter-runner.md` (≥200 words, simple + advanced, API reference).

## 5. Integration tests

- [ ] `tests/integration.test.ts`: create a temp TypeScript file with a lint violation; run `check` → expect `passed: false`; run `fix` → expect fixed; run `format` → expect formatted output; `{ timeout: 30000 }`.

## 6. Docs + verify + publish

- [ ] Root `README.md`: preset usage in `biome.json`, programmatic API quick-start, preset comparison table, API table.
- [ ] `bunx turbo lint --filter=@suaveplan/linter` — zero errors.
- [ ] `bunx turbo typecheck --filter=@suaveplan/linter` — zero errors.
- [ ] `bunx turbo test --filter=@suaveplan/linter` — all pass.
- [ ] `bunx turbo test:coverage --filter=@suaveplan/linter` — 100%.
- [ ] `bun scripts/publish.ts --package @suaveplan/linter`.
- [ ] Update `CLAUDE.md`; archive to `openspec/archive/2026-04-24-enterprise-server-linter/`.
