-Use cases: the built-in registry lives in `src/ix/use_cases/__init__.py` (`bank_statement_header` for MVP). Callers without a registered entry can ship an ad-hoc schema inline via `RequestIX.use_case_inline` (see README "Ad-hoc use cases"); the pipeline builds the Pydantic classes on the fly per request. The `/ui` page exposes this as a "custom" option so non-engineering users can experiment without a deploy.
-
-UX notes: the `/ui` job page surfaces queue position + elapsed MM:SS on each poll, renders the client-provided filename (stored via `FileRef.display_name`, optional metadata — the pipeline ignores it for execution), and shows a CPU-mode notice when `/healthz` reports `ocr_gpu: false`.
+Status: design phase. Full reference spec at `docs/spec-core-pipeline.md`. MVP spec will live at `docs/superpowers/specs/`.

 Given a document (PDF, image, text) and a named *use case*, ix returns a structured JSON result whose shape matches the use-case schema — together with per-field provenance (OCR segment IDs, bounding boxes, cross-OCR agreement flags) that let the caller decide how much to trust each extracted value.

-A minimal browser UI lives at [`http://192.168.68.42:8994/ui`](http://192.168.68.42:8994/ui): drop a PDF, pick a registered use case or define one inline, submit, see the pretty-printed result. HTMX polls the job status every 2 s until the pipeline finishes. LAN-only, no auth.

 - **On-prem always.** LLM = Ollama, OCR = local engines (Surya first). No OpenAI / Anthropic / Azure / AWS / cloud.
 - **Grounded extraction, not DB truth.** ix returns best-effort fields + provenance; the caller decides what to trust.
 - **Transport-agnostic pipeline core.** REST + Postgres-queue adapters in parallel on one job store.
-
-## Submitting a job
-
-```bash
-curl -X POST http://192.168.68.42:8994/jobs \
-  -H "Content-Type: application/json" \
-  -d '{
-    "use_case": "bank_statement_header",
-    "ix_client_id": "mammon",
-    "request_id": "some-correlation-id",
-    "context": {
-      "files": [{
-        "url": "http://paperless.local/api/documents/42/download/",
-        "headers": {"Authorization": "Token …"}
-      }],
-      "texts": ["<Paperless Tesseract OCR content>"]
-    }
-  }'
-# → {"job_id":"…","ix_id":"…","status":"pending"}
-```
-
-Poll `GET /jobs/{job_id}` until `status` is `done` or `error`. Optionally pass `callback_url` to receive a webhook on completion (one-shot, no retry; polling stays authoritative).
-
-### Ad-hoc use cases
-
-For one-offs where a registered use case doesn't exist yet, ship the schema inline:
-
-```jsonc
-{
-  "use_case": "adhoc-invoice",        // free-form label (logs/metrics only)
-  "use_case_inline": {
-    "use_case_name": "Invoice totals",
-    "system_prompt": "Extract vendor and total amount.",
-    "fields": [
-      {"name": "vendor", "type": "str", "required": true},
-      {"name": "total",  "type": "decimal"},
-      {"name": "currency", "type": "str", "choices": ["USD", "EUR", "CHF"]}
-    ]
-  },
-  // ...ix_client_id, request_id, context...
-}
-```
-
-When `use_case_inline` is set, the pipeline builds the response schema on the fly and skips the registry. Supported types: `str`, `int`, `float`, `decimal`, `date`, `datetime`, `bool`. `choices` is only allowed on `str` fields. Precedence: inline wins over `use_case` when both are present.
-
-Full REST surface + provenance response shape documented in the MVP design spec.
-
-## Running locally
-
-```bash
-uv sync --extra dev
-uv run pytest tests/unit -v                    # hermetic unit + integration suite
-IX_TEST_OLLAMA=1 uv run pytest tests/live -v    # needs LAN access to Ollama + GPU
-```
-
-### UI queue + progress UX
-
-The `/ui` job page polls `GET /ui/jobs/{id}/fragment` every 2 s and surfaces:
-
-- **Queue position** while pending: "Queue position: N ahead — M jobs total in flight (single worker)" so it's obvious a new submission is waiting on an earlier job rather than stuck. "About to start" when the worker has just freed up.
-- **Elapsed time** while running ("Running for MM:SS") and on finish ("Finished in MM:SS").
-- **Original filename** — the UI stashes the client-provided upload name in `FileRef.display_name` so the browser shows `your_statement.pdf` instead of the on-disk UUID.
-- **CPU-mode notice** when `/healthz` reports `ocr_gpu: false` (the Surya OCR client observed `torch.cuda.is_available() == False`): a collapsed `<details>` pointing at the deployment runbook.

 ## First deploy
 
-- **Date:** 2026-04-18
-- **Commit:** `fix/ollama-extract-json` (#36, the last of several Docker/ops follow-ups after PR #27 shipped the initial Dockerfile)
-- **`/healthz`:** all three probes (`postgres`, `ollama`, `ocr`) green. First-pass took ~7 min for the fresh container because Surya's recognition (1.34 GB) + detection (73 MB) models download from HuggingFace on first run; subsequent rebuilds reuse the named volumes declared in `docker-compose.yml` and come up in <30 s.
-- **E2E extraction:** `bank_statement_header` against `tests/fixtures/synthetic_giro.pdf` with Paperless-style texts:
-  - Pipeline completes in **35 s**.
-  - Extracted: `bank_name=DKB`, `account_iban=DE89370400440532013000`, `currency=EUR`, `opening_balance=1234.56`, `closing_balance=1450.22`, `statement_date=2026-03-31`, `statement_period_end=2026-03-31`, `statement_period_start=2026-03-01`, `account_type=null`.
-  - Provenance: 8 / 9 leaf fields have sources; 7 / 8 `provenance_verified` and `text_agreement` are True. `statement_period_start` shows up in the OCR but normalisation fails (dateutil picks a different interpretation of the cited day); to be chased in a follow-up.

-### Docker-ops follow-ups that landed during the first deploy
-
-All small, each merged as its own PR. In commit order after the scaffold (#27):
-
-- **#31** `fix(docker): uv via standalone installer` — Python 3.12 on Ubuntu 22.04 drops `distutils`; Ubuntu's pip needed it. Switched to the `uv` standalone installer, which has no pip dependency.
-- **#32** `fix(docker): include README.md in the uv sync COPY` — `hatchling` validates the readme file exists when resolving the editable project install.
-- **#33** `fix(compose): drop runtime: nvidia` — the deploy host's Docker daemon doesn't register a named `nvidia` runtime; `deploy.resources.devices` is sufficient and matches immich-ml.
-- **#34** `fix(deploy): network_mode: host` — `postgis` is bound to `127.0.0.1` on the host (security hardening T12). `host.docker.internal` points at the bridge gateway, not loopback, so the container couldn't reach postgis. Goldstein uses the same pattern.
-- **#35** `fix(deps): pin surya-ocr ^0.17` — earlier cu124 torch pin had forced surya to 0.14.1, which breaks our `surya.foundation` import and needs a transformers version that lacks `QuantizedCacheConfig`.
-- **#36** `fix(genai): drop Ollama format flag; extract trailing JSON` — Ollama 0.11.8 segfaults on Pydantic JSON Schemas (`$ref`, `anyOf`, `pattern`), and `format="json"` terminates reasoning models (qwen3) at `{}` because their `<think>…</think>` chain-of-thought isn't valid JSON. Omit the flag, inject the schema into the system prompt, extract the outermost `{…}` balanced block from the response.
-- **volumes** — named `ix_surya_cache` + `ix_hf_cache` mount `/root/.cache/datalab` + `/root/.cache/huggingface` so rebuilds don't re-download ~1.5 GB of model weights.
-
-Production notes:
-
-- `IX_DEFAULT_MODEL=qwen3:14b` (already pulled on the host). Spec listed `gpt-oss:20b` as a concrete example; swapped to keep the deploy on-prem without an extra `ollama pull`.
-- Torch 2.11 default cu13 wheels fall back to CPU against the host's CUDA 12.4 driver — Surya runs on CPU. Expected inference times: seconds per page. Upgrading the NVIDIA driver (or pinning a cu12-compatible torch wheel newer than 2.7) will unlock GPU with no code changes.
