# crafting-table

Polyglot dev/build/audit container — the build farm for the Sulkta ecosystem.

## What this is

A single Docker container with every toolchain we work with, fronted by a
FastAPI HTTP API + async job runner. Used as a reliable place to compile /
test / audit any Sulkta repo regardless of where the caller is — agents,
Claude sessions, ad-hoc curl, scheduled cron.

Eventual surface (v0.1 full): HTTP API + MCP server + project registry +
job runner + structured findings + email digest + autonomous patch loop
through clawdforge.

Spec: `Sulkta-Coop/openclaw-workspace/memory/spec-crafting-table.md` (LAN-only).

## Status — v0.1

- [x] Step 1: Dockerfile + per-language smoke
- [x] Step 2: SQLite ledger + project registry
- [x] Step 3: HTTP API skeleton (FastAPI, port 8810)
- [x] Step 4: Job runner core (asyncio worker pool, git worktree, subprocess)
- [ ] Step 5: Per-language parsers (Rust / Python / Go / TS first)
- [ ] Step 6: Findings extraction + storage
- [ ] Step 7: MCP server (stdio JSON-RPC, 8 tools)
- [x] Step 8: Email digest scheduler
- [ ] Step 9: Autonomous patch loop (clawdforge integration)
- [ ] Step 10: Production recipes — clawdforge, cauldron, tradecraft

## HTTP API surface

LAN-only. Every request needs `Authorization: Bearer <token>`. The default
LAN allowlist is `10/8`, `172.16/12`, `192.168/16`, `127/8`, `::1/128`;
override via `CRAFTING_LAN_CIDRS`.

| Method | Path                              | Who    | What                           |
|--------|-----------------------------------|--------|--------------------------------|
| GET    | `/healthz`                        | LAN    | Liveness + runner stats        |
| POST   | `/admin/tokens`                   | admin  | Mint a new bearer              |
| GET    | `/admin/tokens`                   | admin  | List tokens                    |
| DELETE | `/admin/tokens/{name}`            | admin  | Revoke a token                 |
| POST   | `/projects`                       | any    | Register (becomes owner)       |
| GET    | `/projects`                       | any    | List own (or all if admin)     |
| GET    | `/projects/{name}`                | owner  | Detail (404 if not visible)    |
| PUT    | `/projects/{name}`                | owner  | Update                         |
| DELETE | `/projects/{name}`                | owner  | Remove (cascades jobs+findings)|
| POST   | `/projects/{name}/jobs`           | owner  | Enqueue a recipe run           |
| GET    | `/jobs?project=&status=&limit=`   | any    | List own (or all if admin)     |
| GET    | `/jobs/{id}`                      | owner  | State + last 200 log lines     |
| GET    | `/jobs/{id}/log`                  | owner  | Full log (file stream)         |
| GET    | `/jobs/{id}/findings`             | owner  | Structured findings (wave 1: empty) |

Cross-token access returns **404, not 403** — same existence-leak guard as
clawdforge sessions.

## Quickstart

After build + first boot, the admin bearer is written to
`/data/admin-bearer.txt` (chmod 600 inside the container — readable from
the bind-mounted appdata path on the host).

```bash
ADMIN=$(cat /mnt/user/appdata/crafting-table/data/admin-bearer.txt)

# Mint a project-scoped token
TOKEN=$(curl -s http://192.168.0.5:8810/admin/tokens \
  -H "Authorization: Bearer $ADMIN" \
  -H "content-type: application/json" \
  -d '{"name":"clawdforge","is_admin":false,"ip_cidrs":[]}' | jq -r .bearer)

# Register the project
curl -s http://192.168.0.5:8810/projects \
  -H "Authorization: Bearer $TOKEN" \
  -H "content-type: application/json" \
  -d '{
    "name": "clawdforge",
    "git_url": "http://192.168.0.5:3001/Sulkta-Coop/clawdforge.git",
    "default_branch": "main",
    "languages": ["python", "rust"],
    "subprojects": [
      {"path": "clients/python", "language": "python",
       "test": "pytest tests/", "lint": "ruff check .", "audit": "pip-audit",
       "timeout_secs": 600},
      {"path": "clients/rust", "language": "rust",
       "build": "cargo build --release", "test": "cargo test --all",
       "audit": "cargo audit", "timeout_secs": 1800}
    ]
  }'

# Kick off a test job
JOB=$(curl -s http://192.168.0.5:8810/projects/clawdforge/jobs \
  -H "Authorization: Bearer $TOKEN" \
  -H "content-type: application/json" \
  -d '{"recipe":"test","subproject":"clients/python"}' | jq -r .job_id)

# Poll status
watch -n2 "curl -s http://192.168.0.5:8810/jobs/$JOB \
  -H 'Authorization: Bearer $TOKEN' | jq '.job.status, .log_tail[-5:]'"

# Stream the full log
curl http://192.168.0.5:8810/jobs/$JOB/log \
  -H "Authorization: Bearer $TOKEN"
```

## Build + smoke

```bash
docker network inspect sulkta >/dev/null 2>&1 || docker network create sulkta
docker compose build

# Run the per-toolchain hello-world smoke
docker compose run --rm crafting-table /usr/local/bin/smoke.sh
# expect: "=== ALL TOOLCHAINS GREEN ==="

# Bring up the API
docker compose up -d
curl http://192.168.0.5:8810/healthz
```

## Image notes

- Base: `debian:bookworm-slim`. Swift uses the upstream Ubuntu 22.04 tarball
  which links against bookworm's libicu/libstdc++ baseline.
- Runs as non-root user `crafter` (uid 1000) with passwordless sudo. The
  API server runs as `crafter`. Recipe commands run as `crafter` too —
  never elevated to root.
- Volume mount points (production):
  - `/data` — SQLite ledger, admin bearer file, per-job logs
  - `/workspace` — bare clones + per-job worktrees
  - `/caches` — cargo / maven / gradle / npm / pip / bun caches
- Network: external `sulkta` bridge (same one clawdforge + cauldron use).
  Create with `docker network create sulkta` if missing.
- Image size baseline is large (8-15 GB expected). Per spec: that's fine.

## Architecture notes

### Recipe security
Recipe commands run via `/bin/sh -c` so any shell metachar works. This is
**by design** — admins set them. Recipes like `cargo build && cargo test`
work as expected; `; rm -rf /` would too if an admin set it. The container
sandbox + `crafter` user are the safety net, not the recipe parser.

### Workspace strategy
- `/workspace/<project>/.cache/` — bare clone of the upstream
- `/workspace/<project>/<job_id>/` — git worktree pointing at the requested
  branch+sha, removed after the job ends
- Periodic gc (1h timer) prunes worktrees older than 24h and runs
  `git gc --prune=now` on bare clones quiet for >7d

### Recipe immutability
Every job snapshots the project's recipe at run-time
(`recipe_snapshot_json`). Editing a project's recipe doesn't retcon the
view of in-flight or already-finished jobs.

### Process group + timeout
Recipe subprocesses spawn in their own process group via
`start_new_session=True`. On timeout we `os.killpg(pgid, SIGTERM)` and grace
for 10s before escalating to `SIGKILL`. Without process-group kill,
multi-process recipes (cargo build spawning rustc, etc.) could leave
orphans that hold the stdout pipe open.

### Restart resilience
Jobs marked `running` but stranded by a process crash are NOT auto-resumed.
On startup the runner sweeps them to `failed` with `exit_code=-1` and
appends a synthetic log line `[crafting-table] runner restart, job
orphaned`. Callers can re-enqueue if they want.

### SQLite + WAL
Single host, single process — SQLite is plenty. WAL mode (`PRAGMA
journal_mode=WAL` + `synchronous=NORMAL`) gives many readers + one writer
without lock contention. The runner is the only mutator of `jobs`/
`findings`; HTTP workers mostly read.

## Tests

```bash
python3 -m venv .venv && source .venv/bin/activate
pip install -e '.[test]'
pytest tests/
```

## Digest

Daily 06:00 PT email digest. One message per project per day; aggregates the
last 24h of jobs per recipient and sends via SMTP relay (Lucy postfix).

Set the SMTP block in `.env` to enable — leaving `CRAFTING_SMTP_HOST` unset
keeps the scheduler off and logs `digest disabled — CRAFTING_SMTP_HOST not set`
at startup. The `/digests` and `/admin/digest/run-now` endpoints still work
in dry-run mode regardless.

```bash
CRAFTING_SMTP_HOST=postfix.sulkta.com
CRAFTING_SMTP_PORT=587
CRAFTING_SMTP_USER=crafting-table@sulkta.com
CRAFTING_SMTP_PASS=...
CRAFTING_SMTP_FROM=crafting-table@sulkta.com
CRAFTING_SMTP_TLS=1
```

Each project's `notify.email` + `notify.on` fields control delivery:

| `notify.on` event   | When it fires                                          |
|---------------------|--------------------------------------------------------|
| `audit_pass`        | a passing audit job                                    |
| `audit_fail`        | a failing audit job                                    |
| `test_fail`         | a failing test job                                     |
| `lint_warn`         | a lint job with warning-severity findings              |
| `cve_found`         | any job whose findings include a `cve`                 |
| `patch_drafted`     | (wave 3 / step 9) auto-patch was drafted               |
| `nightly_summary`   | catch-all — show ALL jobs in the project's section     |

Empty `notify.on` defaults to `["audit_fail", "cve_found", "patch_drafted"]`.
Empty `notify.email` silently excludes the project.

Manual trigger from the LAN admin token:

```bash
# Render today's digest without sending
curl -sH "Authorization: Bearer $ADMIN" \
  -X POST http://192.168.0.5:8810/admin/digest/run-now \
  -d '{"dry_run": true}' | jq .

# Render an arbitrary date as JSON
curl -sH "Authorization: Bearer $ADMIN" \
  http://192.168.0.5:8810/digests/2026-04-29 | jq .
```

Idempotency: `digest_runs` table holds `UNIQUE(date, project_name)`, so the
06:00 loop is safe to re-fire on the same day — only the first call sends.
