feat(schema): M4.1 — tenant_registry schema + migrate binary
PLATFORM_ARCHITECTURE.md §5c schema as one initial migration: 6 tables + 4 enums + updated_at triggers. cmd/migrate binary (golang-migrate library, embedded SQL). testcontainers round-trip + seed + slug-constraint tests.

# tenant-registry
Multi-tenant glue: orgs, entitlements, API keys, audit.

## What this is
Multi-tenant glue: orgs, entitlements, API keys, audit. Scaffolded under milestone M4.1. See [`platform/docs`](https://gitea.meghsakha.com/platform/docs) for the full architecture context.
**Plane:** Control
**Owner:** @sharang
**Status:** pre-alpha
**Linked milestone:** [M4.1](https://gitea.meghsakha.com/platform/docs/src/branch/main/IMPLEMENTATION_PLAN.md)
## Run locally
```bash
# Prerequisites: Go 1.25+
# Dependencies (Keycloak, pg-app) come from the dev stack — see platform/orca-platform/dev.
# In one terminal — bring up dev dependencies (in the orca-platform clone):
cd /path/to/platform/orca-platform && make dev-up
# In another — run the service:
make dev # APP_ENV=dev, listens on :8090 (Keycloak owns :8080 in the dev stack)
make test # unit tests
make build # compile to ./bin/tenant-registry
```
Env vars (override at the shell):
| Var | Default | Purpose |
|---|---|---|
| `APP_ENV` | `dev` | one of `dev`, `stage`, `prod` |
| `ADDR` | `:8090` | listen address (avoids Keycloak's :8080) |
| `KEYCLOAK_ISSUER` | `http://localhost:8080/realms/breakpilot-dev` | OIDC issuer URL |
| `DATABASE_URL` | empty (in-memory store in skeleton) | Postgres DSN, wired up in the M4.1 schema PR |
## Endpoints
| Method | Path | Returns |
|---|---|---|
| GET | `/healthz` | `{"status":"ok"}` — liveness probe |
| GET | `/v1/tenants/by-slug/{slug}` | 200 with tenant JSON, 404 if missing |
| GET | `/v1/tenants/{id}` | 200 with tenant JSON, 404 if missing |
The skeleton's store is in-memory and pre-seeded with one tenant:
```json
{
"id": "00000000-0000-0000-0000-000000000001",
"slug": "acme",
"name": "Acme Inc.",
"status": "active",
"plan": "professional",
"products": ["certifai", "compliance"]
}
```
So `curl http://localhost:8090/v1/tenants/by-slug/acme` works the moment `make dev` is up.
The full schema (6 tables: `tenants`, `tenant_projects`, `tenant_products`, `tenant_idp_config`, `api_keys`, `audit_log` — per `PLATFORM_ARCHITECTURE.md §5c`) lives at `migrations/0001_init.up.sql`. The handler-layer in-memory store is still wired in by default; the pgx-backed store + the full REST surface lands in **M4.2**.
## Schema migrations (M4.1)
```bash
# Apply all pending migrations against the dev Postgres (assumes
# `make dev-up` in platform/orca-platform is running):
make migrate-up
# Inspect current version:
make migrate-version
# Roll back the most recent migration:
make migrate-down
# Wipe everything (DESTRUCTIVE — only safe against a dev DB):
make migrate-down-all
# Create the next pair of empty migration files:
make migrate-create NAME=add_team_table
```
Migrations are embedded into both `cmd/server` and `cmd/migrate` via `migrations/embed.go`. In production, `cmd/migrate` ships as an Orca init container so the schema is applied before the API server starts (`IMPLEMENTATION_PLAN.md §1.7`: migrations are forward-only and run as an init container before the service).
The migrations package ships three integration tests (require Docker):
| Test | What it asserts |
|---|---|
| `TestMigrate_upDownRoundTrip` | up → all 6 tables + 4 enums exist; down → schema empty; up again succeeds |
| `TestSeed_canInsertAndQuery` | end-to-end insert across all 6 tables, FK cascade behaviour, `audit_log` SET-NULL on tenant delete |
| `TestSlugConstraint` | tenant slug regex enforced (rejects too-short / leading dash / uppercase / underscore) |
Run them with `make test`. Use `make test-short` in environments without Docker.
## Deployment
| Env | URL | How |
|---|---|---|
| dev | `http://localhost:8090` | `make dev` |
| stage | `https://tenant-registry.stage.breakpilot.com` | auto on merge to `main` |
| prod | `https://tenant-registry.breakpilot.com` | manual: tag `vX.Y.Z` + sign-off |
Rollback: `orca rollout undo tenant-registry --env={{env}}`.
