Vayikra 19:20 bikoret tihyeh — "there shall be an examination" — the one
noun Torah gives this function; its root ב-ק-ר is the priest's examining
of a mark by its signs (13:36) and the examining between good and bad
(27:33). The judges' form is v'darashta heitev … v'hineh emet nachon
hadavar / ed-sheker ha'ed (Devarim 13:15, 17:4, 19:18); the question
answered is eichah neda et hadavar asher lo dibro (18:21).
The system was named Shorashim ("roots") for the first thing built. Its
function became the examination of a model's output with the sources in
hand, and Torah re-cuts a name when the function is fixed, with its ki,
never for reach (Bereishit 2:19; 17:5; 32:29; 11:4). Nothing was changed
to fit the name; the root engine stays the pe'ah's reading cycle.
Spec files renamed bikoret_*.md; PRD §0 "The Name"; architecture §1.1;
README's Vayishlach row marked done; Tamid lists what still carries the
old word (Kubernetes resource names, the DB role, the domain, local
paths) and why, for the kohen's cut-over.

# Deployment Architecture
|
|
|
|
Generic architecture shape for a bikoret deployment. Specifics of a particular deployment (hostnames, IPs, account names, credentials) live in the operator's private notes, not in this repo.
|
|
|
|
## Components
|
|
|
|
One Kubernetes namespace runs the following:
|
|
|
|
| Component | Runtime | Purpose |
|
|
|-----------|---------|---------|
|
|
| `vav-pipeline` | Elixir/OTP release | Bereishit cycle, ShemaContext, Cloud, Manna, HTTP API (pe'ah, courtyard, chatzer, kodesh) |
|
|
| `shoresh-engine` | Haskell binary, spawned by vav-pipeline as an Erlang Port (staged into the pod by the `shoresh-engine-install` init container — NOT a sidecar container; a Port is a child process of the BEAM and cannot cross a container boundary) | Root activation, te'amim parsing, gematria |
|
|
| `talmudic-engine` | SWI-Prolog (sidecar via Unix socket) | 613 mitzvot, 13 middot, kushya generation, teiku |
|
|
| `korban-processor` | Python 3.12 (sidecar) | Offering protocol, eish zarah validation |
|
|
|
|
All four run in the same pod. vav-pipeline is the main container; talmudic-engine and korban-processor are sidecars; shoresh-engine runs inside vav-pipeline as an Erlang Port child process, staged in by an init container.
|
|
|
|
## External dependencies
|
|
|
|
| Dependency | Purpose | Contract |
|
|
|-----------|---------|----------|
|
|
| Managed PostgreSQL 17+ | L3 Oral Tradition (append-only) | `DATABASE_URL` env var. Requires SSL. Role with `SELECT, INSERT` only — `UPDATE`, `DELETE` revoked (see migration). |
|
|
| (none — in the images) | L1 Torah filesystem (~29 MB) | Baked into every image at `/mnt/torah`, owned by root with no write bit. No volume. The pipeline hashes the tree at startup and every ten minutes; no cycle runs on a scroll that does not match the pinned hash. |
|
|
| Block-storage PersistentVolume | Manna provision and its ledger (read-write, 1 GiB) | Mount at `/var/lib/bikoret/manna`. Operator writes `today.json` daily; the vessel writes `ledger.json`. |
|
|
| Ingress controller + TLS cert | Public HTTPS access | Cert-manager with Let's Encrypt HTTP-01 is the reference setup. |
|
|
| Container registry | Image distribution | Any registry that supports Docker v2 protocol. |
|
|
|
|
## Kubernetes manifests
|
|
|
|
Kept in `deploy/k8s/`:
|
|
|
|
- `namespace.yaml` — the namespace
|
|
- `configmap.yaml` — non-secret configuration
|
|
- `secrets.yaml` — **template only**; operator fills in `DATABASE_URL`
|
|
- `l1-volume.yaml` — PV and PVC for Torah filesystem (vestigial: L1 is in the images; do not apply)
|
|
- `manna-volume.yaml` — PVC for provision file
|
|
- `deployment.yaml` — the pod with 3 containers + 2 init containers (`shoresh-engine-install`, `migrate`). Four images are still built and pushed; shoresh-engine ships a binary, not a running container.
|
|
- `service.yaml` — ClusterIP and external LoadBalancer
|
|
- `gitea-mcp-deployment.yaml` — separate MCP server for Gitea connector (optional)
|
|
- `gitea-mcp-ingress.yaml` — TLS ingress for the MCP server
|
|
- `gitea-mcp-secret.yaml` — template for Gitea PAT
|
|
- `cert-manager-issuer.yaml` — Let's Encrypt ClusterIssuer
|
|
|
|
## Containers
|
|
|
|
Four Dockerfiles in `deploy/docker/`:
|
|
|
|
- `Dockerfile.vav_pipeline` — multi-stage Elixir 1.16.1 / OTP 26.2.1 release
|
|
- `Dockerfile.shoresh_engine` — multi-stage Haskell GHC 9.6.4 / Cabal
|
|
- `Dockerfile.talmudic_engine` — SWI-Prolog 9.2.2 with socket server
|
|
- `Dockerfile.korban_processor` — Python 3.12.2 slim
|
|
|
|
## Configuration surface
|
|
|
|
The system reads three things from its environment:
|
|
|
|
1. **L1 Torah** — in the image at `$L1_MOUNT_POINT`, not writable by the service user. Read and hashed at startup and every ten minutes; every cycle is gated on the last reading.
|
|
2. **Manna provision** — JSON file at `$MANNA_PROVISION_FILE`, written by the kohen/treasurer.
|
|
3. **L3 database** — connection string in `$DATABASE_URL`.
|
|
|
|
Nothing else is configurable. The system obeys Torah (L1 + calendar) for governance and the provision file for resources.
|
|
|
|
## Seven-day inauguration
|
|
|
|
Before serving users, run the `shiv'at y'mei milu'im` sequence documented in `KOHEN.md`. Each day validates a specific layer. Partial inauguration is no inauguration.
