# Tasks: enterprise-server-seed

**Change ID**: enterprise-server-seed
**Package**: `@suaveplan/seed`
**Target path**: `server/infra/seed`
**Prerequisites on Verdaccio**: `@suaveplan/error`, `@suaveplan/types`, `@suaveplan/db`, `@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 `"."` + `runner` + `graph`.
- [ ] Deps: `@suaveplan/error workspace:^`, `@suaveplan/types workspace:^`, `@suaveplan/db workspace:^`, `@suaveplan/logger workspace:^`, `zod catalog:forms`, `@opentelemetry/api catalog:observability`, `tslib catalog:build`.
- [ ] DevDeps: `vitest catalog:testing`, `@vitest/coverage-istanbul catalog:testing`, `@suaveplan/testing workspace:^`, `@suaveplan/db-sqlite workspace:^`.
- [ ] `tsconfig.json` extending `library-node.json`; `vitest.config.ts` with `createTestConfig()`.
- [ ] Scripts: `lint`, `typecheck`, `test`, `test:coverage`, `build`, `docs:check`.

## 2. Types and errors

- [ ] Define all interfaces and Zod schemas (`SeedDefinitionSchema`, `SeedRunnerOptionsSchema`) in `src/types/seed.types.ts`.
- [ ] Write `seed.types.md` (≥200 words, both examples, API reference).
- [ ] `src/error-codes.ts`: four codes; `registerSeedErrorCodes()`; eager call.

## 3. Dependency graph

- [ ] Implement `src/graph/dependency-graph/dependency-graph.ts`:
  - `topologicalSort(nodes: Map<string, string[]>): string[]` — Kahn's algorithm; throw `SEED_CIRCULAR_DEPENDENCY` on cycle.
  - `validateDependencies(definitions: SeedDefinition[]): void` — throw `SEED_DEPENDENCY_NOT_REGISTERED` if `dependsOn` references unknown names.
- [ ] Write `dependency-graph.test.ts`: linear chain, diamond, cycle detection, missing dependency.
- [ ] Write `dependency-graph.md` (≥200 words).

## 4. Seed runner

- [ ] Implement `SeedRunner` in `src/runner/seed-runner/seed-runner.ts`:
  - `register(definition)`: store in internal Map; validate that name is unique.
  - `run(names?)`: if `names` provided, run only those + their transitive deps; else run all. Topologically sort; execute in order; pass `SeedContext`; handle `condition` (skip if returns false); handle `onConflict`; collect `SeedStepResult`; return `SeedReport`. OTel span `seed.run` per step; counter `seed.steps_total`.
  - `teardown(names?)`: run `teardown` fn for each (in reverse dependency order).
  - Errors from handlers wrapped in `SEED_STEP_FAILED`; other steps continue unless `onConflict === 'error'`.
- [ ] Write `seed-runner.types.ts`.
- [ ] Write `seed-runner.test.ts` (≤500 lines): all steps run; dependency ordering; condition-skip; onConflict modes; teardown reverse order; partial run by names; circular dependency throws before execution.
- [ ] Write `seed-runner.md` (≥200 words, simple + advanced, API reference).

## 5. Integration tests

- [ ] `tests/integration.test.ts`: use `@suaveplan/db-sqlite` with in-memory DB; register three seeds with dependency chain; run → verify DB state; teardown → verify cleanup; `{ timeout: 15000 }`.

## 6. Docs + verify + publish

- [ ] Root `README.md`: quick-start with SQLite, dependency graph example, conditional seeding, API table.
- [ ] `bunx turbo lint --filter=@suaveplan/seed` — zero errors.
- [ ] `bunx turbo typecheck --filter=@suaveplan/seed` — zero errors.
- [ ] `bunx turbo test --filter=@suaveplan/seed` — all pass.
- [ ] `bunx turbo test:coverage --filter=@suaveplan/seed` — 100%.
- [ ] `bun scripts/publish.ts --package @suaveplan/seed`.
- [ ] Update `CLAUDE.md`; archive to `openspec/archive/2026-04-24-enterprise-server-seed/`.
