# sec-cyBERT

Bun workspace monorepo. Three packages:

- `packages/schemas/` — shared Zod schemas (`@sec-cybert/schemas`). Import directly by path: `from "@sec-cybert/schemas/label.ts"`
- `ts/` — GenAI labeling pipeline (CLI scripts, Vercel AI SDK, OpenRouter)
- `labelapp/` — Next.js human labeling webapp (Drizzle, Postgres, shadcn/ui, Playwright)

## Quick reference

| What | Where |
|------|-------|
| Shared schemas (Zod) | `packages/schemas/src/` |
| Labeling codebook (source of truth for all category/specificity definitions) | `docs/LABELING-CODEBOOK.md` |
| Project narrative (decisions, roadblocks, lessons) | `docs/NARRATIVE.md` |
| Implementation plan for labelapp | `docs/labelapp-plan.md` |
| Labelapp-specific agent guide | `labelapp/AGENTS.md` |
| Docker compose (Postgres) | `docker-compose.yaml` (root) |
| DB credentials | `sec_cybert` / `sec_cybert` / `sec_cybert` on localhost:5432 |

## Rules

- `bun` for all JS/TS. `uv` for Python.
- No barrel files. Direct path-based imports only.
- No TODO comments. Finish what you start.
- No parallel codepaths. Find and extend existing code before writing new.
- Schemas live in `packages/schemas/` — do not duplicate type definitions elsewhere.
- `labelapp/` uses flat layout (no `src/` dir): `app/`, `db/`, `lib/`, `components/` at root.
- Tests: `bun test` for backend route integration (`__test__/` dirs adjacent to routes), Playwright for E2E (`tests/`).
