+## HTTP API (current)
+
+| Method | Path | Purpose |
+|--------|------|---------|
+| GET | `/health` | Liveness + default `model` / `text_model` + key/email flags |
+| GET | `/models` | OpenRouter catalog split into `vision[]` / `text[]` + `defaults` (cached ~1h) |
+| POST | `/check` | Upload PDF; returns `{job_id}` immediately |
+| GET | `/jobs/{id}` | Status poll. Running: `stage` + `log_tail`. Done/error: `report` and/or `error` + full `log` |
+| GET | `/jobs/{id}/log` | Full run log JSON (`lines`, `text`); `?plain=1` for text/plain |
+| GET | `/jobs/{id}/sheet-image/{page}` | JPEG of source PDF page for the sheet viewer |
+| GET | `/` | Serves `frontend/index.html` |
+
+### `/check` form fields
+
+- Required: `file` (PDF)
+- Optional: `notification_email`, `project_name`, `address`, `occupancy`, `work_type`
+- Compute: `text_local` (`true` = hybrid local text)
+- Models: `vision_model`, `text_model` (OpenRouter ids; blank = config defaults)
+
+## Job logs
+
+Pipeline `print()` is teed for the job thread ([backend/job_log.py](backend/job_log.py)):
+
+- Live: `GET /jobs/{id}` → `log_tail` (last 80 lines)
+- Done/error: same payload includes full `log`
+- Disk: `backend/outputs/<job_id>/job.log` (survives restart; status registry does not)
+- API: `GET /jobs/{id}/log` or `?plain=1`
+- UI: “Run log” panel updates while running; stays visible after finish/fail
+
+## Vision vs text models
+
+Two models, not one:
+
+| Role | Config | Stages | Backend |
+|------|--------|--------|---------|
+| Vision | `MODEL` | Extract, conflict reason (images) | Always OpenRouter |
+| Text | `TEXT_MODEL` (falls back to `MODEL`) | Sheet index, jurisdiction, normalize, cluster(LLM), QAQC, code, construct, validate, risk, RFI | OpenRouter, or local when hybrid |
+
+UI: two dropdowns filled from `GET /models` ([backend/models_catalog.py](backend/models_catalog.py)). Per-run picks go through `set_model_overrides()` in [backend/llm.py](backend/llm.py); runner clears them in `finally`. Hybrid: text dropdown also names the local model override and OpenRouter fallback.

 1. **Prompt placeholders** — Use `str.replace` via `_stage.render`, never `str.format`. Prompts contain literal `{` JSON braces.
 2. **Clustering** — Default is LLM (`CLUSTERER=llm`); empty LLM result falls back to deterministic. Deterministic clusters need ≥2 disciplines (or schedule-vs-plan); single-discipline “missing” gaps are a known limit.
-3. **Jobs are in-memory** — Process restart clears job status; reports on disk under `backend/outputs/<job_id>/` can still be reloaded via `get_job` disk fallback. Run logs persist as `job.log` in that same folder and via `GET /jobs/{id}/log`.

 4. **Dependency pin** — `httpx==0.27.2` with `openai==1.51.0`. httpx ≥0.28 breaks openai’s `proxies=` kwarg.
 5. **Code corpus licensing** — Only `ada_2010.txt` is shipped. Do not paste IBC/IFC/IECC without a license (see `backend/code_corpus/README.md`).
 6. **Dual assertion schema** — Newer `{sheet, objects[]}` is mapped to legacy `{assertions[]}` with `attribute`/`value` for older stages.
 7. **Grounding guard** — Extractor drops objects whose numeric claims are not in `source_text` (graphical-only objects allowed).
-8. **Cost counters** — Module-global LLM cost accounting; overlapping jobs share counters. Same for stdout tee logging and per-run model overrides.
+8. **Module globals** — LLM cost counters, stdout tee, and model overrides are process-global; overlapping jobs can interleave (single-user tool assumption).
 9. **Samples** — `samples/*.pdf` are gitignored; drop PDFs locally for CLI runs.
 10. **README drift** — Treat README for setup/CI; treat this file + `runner.py` for pipeline truth. `prompts.py` header may still say some prompts are unwired — they are wired through the runner.
-11. **Two models** — Vision (`MODEL`, image stages) and text (`TEXT_MODEL`, non-image). UI exposes separate dropdowns from OpenRouter’s `/models` (cached ~1h). Hybrid still runs vision on OpenRouter; text dropdown also covers local name override + cloud fallback.

+12. **No local Python deps on host** — App is meant to run in Docker; bare `python3` imports may miss `dotenv` / `httpx`. Prefer `docker compose`.
 
 ## Quick start pointers
 
 - Full setup: [README.md](README.md) (`docker compose up -d --build` → http://localhost:8099).
 - Local CLI: `python cli/run_check.py samples/your_set.pdf --out out/your_set`.
 - Prompt iteration: set `LLM_CACHE=true` in `backend/.env` so unchanged stages replay for free; clear with `rm -rf backend/.llm_cache`.
-- Artifacts: `assertions.json`, `clusters.json`, per-stage JSON, `conflicts.json`, `report.md` under the chosen `out_dir` or `backend/outputs/`.
+- Artifacts per job: `assertions.json`, `clusters.json`, per-stage JSON, `conflicts.json`, `report.md`, `job.log`, `source.pdf` under `backend/outputs/<job_id>/`.
 - No automated test suite; validate via CLI dumps and golden-set diffs (described in README).
