+# Document workbench — upload → structure → validated export
+
+The customer-facing slice that turns an uploaded file into evidence-bound data.
+
+## Routes
+
+| Route | Purpose | Fails closed with |
+|---|---|---|
+| `POST /api/0pt/documents/upload` | multipart upload of the original bytes into DOC0, recorded in a durable attempt journal before dispatch | `503 DOC0_NOT_CONFIGURED`, `503 PROJECT_AUTHORIZATION_NOT_CONFIGURED`, `503 UPLOAD_JOURNAL_NOT_CONFIGURED` |
+| `POST /api/0pt/documents/structure` | re-reads the DOC0 segment index, calls INF0, validates every field against an exact source span, reserves/settles credits | `503 WORKBENCH_NOT_CONFIGURED`, `503 MODEL_POLICY_NOT_CONFIGURED`, `503 CREDITS_NOT_CONFIGURED`, `402 INSUFFICIENT_CREDITS` |
+| `GET /api/0pt/documents/models` | the server-approved model routes and limits | `503 MODEL_POLICY_NOT_CONFIGURED` |
+| `GET /api/0pt/credits/balance` | tenant credit balance | `503 CREDITS_NOT_CONFIGURED` |
+| `GET /api/0pt/credits/packs` | sellable packs from the server-owned price book | `503 PRICE_BOOK_NOT_CONFIGURED` |
+| `POST /api/0pt/credits/checkout` | Stripe Checkout session + server price snapshot | `503 PRICE_BOOK_NOT_CONFIGURED`, `503 STRIPE_NOT_CONFIGURED` |
+| `POST /api/webhooks/stripe` | re-reads the session and payment intent, then grants credits idempotently | non-2xx until processed |
+
+UI: `/portal/dokument` (upload, structure, review, download) and `/portal/krediter`
+(balance, packs, checkout). The portal signs in through Zitadel OIDC
+(`/api/auth/login` → `/api/auth/callback`); the resulting signed session cookie
+is accepted by middleware as a verified principal (Bearer still wins).
+
+## Invariants
+
+1. **Tenant and actor come only from middleware's verified headers.** A customer
+   route never trusts `tenant_id`/`actor_id` from the body.
+2. **Project access is checked by OpenFGA** (`@siax/access`), the same primitive
+   DOC0 uses. Until the central relationship store is deployed, an explicit
+   server-owned grant list (`OPT_PROJECT_GRANTS`) can be used instead.
+   Unconfigured or unavailable means *denied*, never allowed.
+3. **The model never sees unverified text.** `Doc0SourceClient` verifies
+   version, tenant, checksum, segment hashes and that the index was not
+   truncated before anything is sent to INF0.
+4. **Every returned value must point at an exact span** in the source; otherwise
+   the result is `needs_review` and nothing is exported.
+5. **Credits are reserved before the model runs and settled to measured usage.**
+   An unknown model outcome keeps the reservation for reconciliation instead of
+   releasing it.
+6. **No price is ever read from the client.** The price book is a versioned,
+   server-owned JSON document (`OPT_CREDIT_PRICE_BOOK`).
+7. **Trial credits are a grant, not a payment.** `OPT_TRIAL_CREDITS=N` grants N
+   credits once per tenant (`kind='grant'`, idempotency key `trial:<tenant>`),
+   so the ledger is fully exercised before any real purchase. It is never read
+   from a client and never looks like a Stripe payment.
+8. **Pilot mode is explicit.** `OPT_CREDITS_MODE=off` skips reserve/settle and
+   reports `credits: null`. It is not a silent fallback and it does not enable
+   purchases; unset/`on` requires the price book and the ledger.
+
+## Reusable packages
+
+- `packages/siax-access` (`@siax/access`) — framework-neutral OpenFGA
+  relationship checks and a fail-closed `isProjectAccessAllowed`. Intended for
+  DOC0, N0D and every other SIAX product instead of per-repo copies of
+  `project-relationships.ts`.
+- `src/document-workbench/*` — upload coordination, DOC0 source reading, INF0
+  admission, structured-output validation, export and credit ledger. These
+  modules have no Next.js imports and can be lifted into a published package
+  unchanged.
+
+## Which AI path is used
+
+Order:
+1. **Decision server model** (`DECISION_OLLAMA_URL` + `DECISION_OLLAMA_MODEL`) —
+   the self-hosted Ollama on server-decision-01, used while the external model
+   API is on hold. Internal only, no provider key, no per-token cost.
+2. **Live LiteLLM gateway** (`INF0_GATEWAY_LITELLM_KEY`).
+3. Native `INF0_URL` surface.
+
+Admission — tenant/project scope, model allow-list, data class,
+external-transfer policy and token limits — runs locally in every path before
+the request leaves the process. Evidence spans are computed deterministically
+from the returned values when a small local model omits offsets: a value must
+occur exactly once in the source, otherwise the result is `needs_review`.
+
+## What is still deliberately not claimed
+
+- The output is `mechanically_validated`, not proven complete or semantically
+  correct. OCR quality and coverage require review.
+- Refunds and chargebacks do not automatically revoke credits; no such handler
+  is wired.
+- Format breadth is limited by DOC0's parser. A file DOC0 cannot parse is
+  reported, never guessed.

-
-## 2. Deploy (när appen finns)
-
-1. Push till `main` → `.gitea/workflows/cd.yml` POSTar till
-   `https://cloud.siax.io/api/v1/deploy?uuid=$COOLIFY_APP_ID&force=false`,
-   efter att den signerade-artefakt-grinden i punkt 1b gått grön.
-2. Följ run i Gitea Actions; verifiera att den slutar grön.
-3. Verifiera hälsa: `curl https://0pt.app/api/health` → `ok:true` och
-   `db: configured` (när Postgres kopplats in).
-
-## 3. Manuell redeploy (nöd)
-
-```bash
-curl -fsS -X POST "https://cloud.siax.io/api/v1/deploy?uuid=<UUID>&force=true" \
-  -H "Authorization: Bearer $COOLIFY_TOKEN"
+```
+git push main
+  ├─ ci.yml        quality (typecheck, contrast, tests, build)
+  │                integration (live OpenSearch + ClickHouse)
+  │                security (Trivy, blocking)
+  ├─ security.yml  push/PR/weekly scan

+  └─ cd.yml        waits for THIS commit's attestation, verifies it against
+                   cosign.pub, then POSTs to Coolify
+prod-smoke.yml     every 30 min: ready + db/stripe + running commit == main
 ```
 
-## 4. Vercel-avveckling (EFFER att Coolify kör stabilt)
+- One run per ref (`concurrency`); `push` is main-only, PRs are covered by the
+  `pull_request` event. Deploys have their own non-cancelling group so two
+  runs never race the same app.
+- Dependency caches: pnpm store (Node jobs), npm (doc0/n0d), pip (0pt-motor).
 
-1. Verifiera att ingen verklig trafik/data ligger bakom (2026-08-10:
-   `/api/health` visar `db/queue: not_configured` — marknads-/dev-läge).
-2. Peka DNS om till Coolify. 3. Behåll Vercel-projektet tills certifierad
-   paritet (katalog, orderflöde, betalningar). 4. Avveckla först därefter.
+## Manual deploy (proven)
+
+Trigger the same, signed path — do not POST to Coolify directly unless the
+pipeline itself is broken:
+
+```bash
+curl -X POST -H "Authorization: token $GITEA_TOKEN" -H "Content-Type: application/json" \
+  -d '{"ref":"main"}' \
+  https://git.siax.io/api/v1/repos/admin/0pt/actions/workflows/cd.yml/dispatches
+```
+
+Emergency only (bypasses the attestation gate; still builds the branch head):
+
+```bash
+curl -X POST -H "Authorization: Bearer $COOLIFY_API_TOKEN" -H "Content-Type: application/json" \
+  -d '{"uuid":"<COOLIFY_APP_ID>"}' https://cloud.siax.io/api/v1/deploy
+```
+
+## Verify a deploy
+
+```bash
+curl -s https://0pt.app/api/ready     # {"ready":true,"db":"ok","stripe":"ok",...}
+curl -s https://0pt.app/api/health    # liveness envelope
+curl -s https://0pt.app/api/version   # {"commit":"<sha>"}
+```
+
+`commit` must equal the current `main` SHA. `prod-smoke.yml` enforces exactly
+that every 30 minutes; a green deploy is never confused with a current service.
+
+## Rollback
+
+Coolify builds from the branch head, so a rollback is a normal revert:
+
+```bash
+git revert --no-edit <bad-sha> && git push origin main
+```
+
+That runs the same chain and deploys the reverted tree. Coolify's own
+"redeploy previous deployment" is the break-glass alternative.
+
+## Configuration (names only — values live in Coolify/Infisical)
+
+- Coolify app: `dockerfile` build pack, repo `git.siax.io/sax3l/0pt`, branch
+  `main`, health check `/api/health`, domains `0pt.app` + `api.0pt.app`.
+- Repository variable: `COOLIFY_APP_ID`.
+- Repository secrets: `COOLIFY_TOKEN`, `REGISTRY_USER`, `REGISTRY_TOKEN`,
+  `COSIGN_PRIVATE_KEY`, `COSIGN_PASSWORD`, `SIAX_CI_TOKEN`.
+- App env: `DATABASE_URL`, `STRIPE_SECRET_KEY`, `AUTH_SECRET`… see `.env.example`
+  for the full, documented list (DOC0, INF0/decision Ollama, OpenFGA/project
+  grants, model policy, credit price book, OIDC).
+
+## Known limitation
+
+Coolify rebuilds from source; `/api/v1/deploy` has no digest parameter, so the
+verified digest is recorded as provenance for the deploy rather than pinned as
+the running bytes. True digest pinning would require a Coolify `dockerimage`
+resource — an infrastructure decision, not a CI-YAML change.

+
+## Surface
+
+Serves the BI-P068 operation paths under `/api/0pt/analytics`:
+
+- `GET /health`
+- `GET /datasets`, `GET /datasets/{id}`
+- `GET /metrics`, `GET /metrics/{id}`, `GET /metrics/{id}/explain`
+- `POST /metrics/{id}/query`
+- `POST /query`, `POST /query/estimate`, `POST /query/explain`
+- `GET /query/{id}` (404: executions are not persisted yet)
+- `GET /dashboards`, `GET /reports` (empty until the BI metadata lane writes them)
+- `GET /search`
+
+Identity: the caller's Keycloak token is verified against the portal realm
+JWKS; `tenant_id` is taken from the token and cross-checked against
+`X-Tenant-Id`. An `X-Internal-Token` path exists only for the ingestion worker.
+
+## Ingest
+
+`ingest_aud0.py` maps AUD0 audit events to `opt_analytics_event`
+(`dataset_id=aud0.events`, `metric=event_count`, dimensions event_type/app_id/
+capability_id/risk_level). It is idempotent per `event_id`.
+
+```bash
+AUD0_TOKEN=... AUD0_TENANT_ID=... CLICKHOUSE_URL=http://opt-analytics-clickhouse:8123 \
+  python ingest_aud0.py --limit 50000

+0pt analytics HTTP surface (BI-P068-compatible).
+
+This is the missing read plane between API0's `/analytics/*` contract and the
+`opt_analytics` ClickHouse database. It does not invent a second analytics
+model:
+
+  * datasets/metrics are the distinct ids actually present in
+    `opt_analytics_event` / `opt_metric_daily` / `opt_dataset_projection`;
+  * query/estimate/explain are computed against the tenant-forced ClickHouse

+  * dashboards/reports are honest empty lists until the 0pt BI metadata lane
+    writes them;
+  * every response is either real ClickHouse data or an explicit error.

+IDENTITY. API0 verifies the caller and forwards the caller's own Keycloak
+token plus `X-Tenant-Id`. This service verifies the same token against the
+portal realm's JWKS and cross-checks `tenant_id` against `X-Tenant-Id`. A
+service-to-service `X-Internal-Token` is also accepted for the ingestion
+worker, but never for a request that reads tenant data without an explicit,
+already-verified `X-Tenant-Id`.

+Backfill/refresh: AUD0 events -> 0pt ClickHouse analytics events.

+One audit event becomes one analytics event with metric `event_count` and
