Merge main: dual model dropdowns + richer job logs, adapted for agent-mode.

- llm.py: set_model_overrides(vision, text) replaces the single job override;
  UI picks still beat per-call agent model args, but never name the hybrid
  local model (avoids main's hybrid footgun); local->cloud fallback uses the
  text pick.
- jobs.py: timestamped line-split tee (job_log.py), in-memory log + log_tail
  polls, full log on terminal states (done/error/needs_review/finalization_error),
  log-only disk recovery, error email links to the run log, and failed runs now
  append the full traceback to job.log. Keeps pipeline_mode, job.json, and the
  review gate.
- models.py: vision/text split via architecture modalities, pricing kept;
  /models returns {vision, text, defaults}; /check takes vision_model/text_model
  (replacing model); /health adds text_model. models_catalog.py dropped.
- UI: two priced dropdowns (OpenRouter compute only) + live run-log panel.
- Tests updated for dual overrides and the /models shape; new coverage for
  traceback capture and local-model immunity.

+The Classic pipeline remains the recommended default. The experimental Agent
+fork runs in the same image and can be selected in the web UI or from the CLI:
+
+```bash
+python cli/run_check.py samples/your_set.pdf --mode agent --out out/agent-run
+```
+
+Agent mode uses OpenRouter for every model call and runs bounded specialist
+waves: one-sheet extraction, sheet-index/jurisdiction orientation, semantic
+linkers partitioned by level and object family, per-cluster conflict critics,
+batched code review, cluster-scoped constructability, summary-only completeness,
+central Brain consolidation, and one-finding RFI writers. It returns the same
+`conflicts`, `validated_issues`, `rfis`, and `summary` fields as Classic.
+
+Agent artifacts are also written under `<output>/agent/`, including wave
+snapshots and the final Project Memory. `summary.agent_stats`,
+`summary.cost_by_stage`, and `summary.models_used` are job-local, so concurrent
+Agent jobs do not share accounting.
+
+Optional `AGENT_*_MODEL` variables select an OpenRouter model per specialist.
+The `AGENT_*_CONCURRENCY` and scope-cap variables in `backend/.env.example`
+bound fan-out and prompt size. Agent mode intentionally ignores the hybrid/local
+text option in v1.
+
+### Agent mode: required human review
+
+By default (`AGENT_REQUIRE_REVIEW=true`) an Agent run **stops after the Brain
+consolidation wave** and waits for a human before anything ships:
+
+```
+Brain merge  ->  needs_review  ->  review UI (/?job=<id>)  ->  finalize  ->  final report
+```
+
+The job lifecycle adds review states: `needs_review` (queue built, waiting),
+`reviewing` (decisions submitted), `finalizing` (targeted reruns + RFI writers
+running), then `done` — or `finalization_error` if finalization fails. Open the
+job in the web UI to work the queue: blocking items (high/critical severity,
+low confidence, sensitive categories) must be decided; clean-cluster items are
+non-blocking spot-checks.
+
+Email is **two-phase**: a "review required" notice goes out when the job enters
+`needs_review` (with a link to the review UI); the final conflict report email
+is only sent after finalization completes. The unreviewed report never leaves
+the server.
+
+**Privacy boundary:** all review artifacts (queue, decisions, final report) are
+job-local under `outputs/<job_id>/review/`. Cross-job review-feedback
+aggregation, when built, excludes verbatim `source_text`, images, and comments
+unless `REVIEW_AGGREGATE_INCLUDE_TEXT=true`.
+
+Config knobs (see `backend/.env.example`):
+
+| Key | Default | Effect |
+|-----|---------|--------|
+| `AGENT_REQUIRE_REVIEW` | `true` | `false` = Agent jobs skip the gate entirely (old behavior: RFIs, final report, one email) |
+| `AGENT_REVIEW_AUDIT_SAMPLE` | `5` | Max clean clusters added to the queue as spot-checks |
+| `REVIEW_AGGREGATE_INCLUDE_TEXT` | `false` | Allow future aggregate feedback to include source text/images/comments |
+
+From the CLI, `--no-review` bypasses the gate for that run (it overrides
+`AGENT_REQUIRE_REVIEW=true`):
+
+```bash
+python cli/run_check.py samples/your_set.pdf --mode agent --no-review --out out/agent-run
+```
+
+**Deployment note:** the review endpoints (`/jobs/{id}/review-decisions`,
+`/jobs/{id}/finalize-review`) are **state-changing and sensitive** — they accept
+human decisions that alter the final report. Do **not** expose the UI/API
+publicly without reverse-proxy auth or a shared access token in front of it.

+# Agent Human Review Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add required human review to the Agent pipeline so findings are confirmed, rejected, clarified, and measured before final RFIs/reports are issued.
+
+**Architecture:** Keep the existing Agent pipeline through Brain, then insert a ReviewGate that writes a persistent review queue and moves the job to `needs_review`. A ReviewFinalizer applies human decisions, performs bounded targeted reruns for clarification, drafts RFIs only for kept issues, and only then marks the job done and sends final email.
+
+**Tech Stack:** Python 3, FastAPI, pytest, vanilla JS frontend, JSON file artifacts under `backend/outputs/<job_id>/`.
+
+## Global Constraints
+
+- Do not change Classic pipeline behavior.
+- Agent mode remains OpenRouter-only in v1.
+- No final email before human review finalization.
+- No raw `source_text`, sheet images, or drawing content in aggregate metrics by default.
+- All new review logic must have non-LLM tests.
+- Follow existing patterns: small modules, graceful degradation, JSON artifacts under job output dir.
+- Review endpoints are state-changing and must be treated as sensitive in docs and deployment notes.
+
+---
+
+### Task 1: Review schemas and policy

+- Create: `backend/review/schemas.py`

+  - `validate_decision(raw: dict) -> dict | None`
+  - `requires_review(issue: dict) -> list[str]`
+  - `build_audit_sample(memory_snapshot: dict, prioritized: list[dict], limit: int = 5) -> list[dict]`

+# Required Human Review for Agent Pipeline Design
+
+**Date:** 2026-07-28  
+**Status:** Approved  
+**Owner:** Conflict Checker Agent pipeline
+
+## Goal
+
+Make Agent mode produce higher-quality findings by requiring structured human review before final RFIs/reports are issued, and by turning review decisions into usable feedback for future prompt, rule, threshold, and evaluation improvements.
+
+## Background
+
+Agent mode is intended to replace Classic mode. Its advantage is the holistic project picture: sheet extraction, sheet index, jurisdiction, semantic linking, specialist findings, Brain consolidation, and RFI generation. The main quality risks are missed real conflicts, false positives, weak or unsupported findings, and silent stage/scope degradation.
+
+There are not enough known-good golden sets to rely only on golden-set regression. Human review becomes the feedback mechanism. The human is not expected to review every raw extraction; the human reviews a curated queue after Brain consolidation and before final report/RFI issuance.
+
+## Requirements
+
+### Functional requirements
+
+1. Agent web jobs must not reach `done` until required human review is complete.
+2. The Agent pipeline runs through Brain, then enters `needs_review`.
+3. RFI generation happens only after review finalization.
+4. Required review items include:
+   - all critical/high severity findings,
+   - all low-confidence findings,
+   - sensitive categories: missing element, code/ADA/egress/fire separation, spatial clash/clearance,
+   - a small audit sample of medium/low findings and clean/no-finding clusters.
+5. Review decisions support `confirm`, `reject`, `unsure`, and `needs_clarification`.
+6. Rejections require a reason code.
+7. Review progress persists to disk and survives server restart.
+8. Rejected findings are suppressed, not deleted.
+9. Clarifications are stored as first-class artifacts.
+10. Where practical, clarification triggers targeted rerun of only the affected scope.
+11. Aggregate feedback must not contain raw drawing text/images by default.
+12. Classic mode remains unchanged.
+
+### Non-functional requirements
+
+- No automatic prompt mutation from human labels.
+- No final email before review completion.
+- Review endpoints must be treated as state-changing and sensitive.
+- Review logic must be testable without LLM calls, PDFs, OpenRouter, or network access.
+- Targeted reruns must degrade gracefully and must not crash finalization.
+
+## Architecture
+
+Add three small components.
+
+### ReviewGate
+
+Runs after Brain and before RFI/report finalization.
+
+Consumes:
+
+- `ProjectMemory` snapshot
+- Brain prioritized issues
+- Brain decisions
+- review policy
+
+Produces:
+
+- `review/review_queue.json`
+- candidate report with `summary.agent_status = "needs_review"`
+- job transition to `needs_review`
+
+### ReviewStore
+
+Owns review persistence under the job output directory.
+
+Stores:
+
+- `review/review_queue.json`
+- `review/review_decisions.json`
+- `review/review_progress.json`
+
+Writes must be atomic using a temporary file plus `os.replace`, matching the existing LLM cache/report artifact style.
+
+### ReviewFinalizer
+
+Runs after required decisions are submitted.
+
+Responsibilities:
+
+- validate completeness,
+- apply decisions,
+- perform bounded targeted reruns for clarification where supported,
+- re-run Brain only for affected findings,
+- draft RFIs only for kept/confirmed issues,
+- write final artifacts,
+- transition to `done`,
+- send final email.
+
+## Job lifecycle
+
+Current lifecycle:
+
+`queued -> running -> done -> email`
+
+New Agent lifecycle:
+
+`queued -> running -> needs_review -> reviewing -> finalizing -> done -> email`
+
+Additional failure state:
+
+- `finalization_error`
+
+If the server restarts while a job is in `needs_review` or `reviewing`, the backend rebuilds state from `outputs/<job_id>/conflicts.json`, `outputs/<job_id>/review/review_queue.json`, and `outputs/<job_id>/review/review_decisions.json`.
+
+## Email behavior
+
+If email is enabled, Agent mode sends two emails:
+
+1. **Review required** when the job enters `needs_review`.
+2. **Final report** only after review finalization.
+
+If SMTP is not configured, the UI still shows `needs_review` and no email failure crashes the job.
+
+## Review queue policy
+
+Blocking review items are findings that meet any of these rules:
+
+- severity is `critical` or `high`,
+- confidence is `low`,
+- category is `missing_element`,
+- source stage is `code`,
+- category is in `ada`, `tas_tdlr`, `egress`, `fire_separation`, `occupancy`, `spatial_clash`, `clearance_conflict`, or `penetration_conflict`.
+
+Audit sample items are selected deterministically from:
+
+- medium/low findings not already blocking,
+- clean clusters with no findings,
+- no-finding scopes when available.
+
+Default audit sample size is 5 items.
+
+## Review decision schema
+
+```json
+{
+  "review_item_id": "finding:AGENT-0007",
+  "decision": "reject",
+  "reason_code": "same_value_different_representation",
+  "category_correction": null,
+  "severity_correction": null,
+  "comment": "9'-0\" AFF and 108 inches are the same value here.",
+  "clarification_answer": null,
+  "reviewed_at": "2026-07-28T12:00:00Z"
+}
+```
+
+Allowed reason codes:
+
+- `wrong_cluster_link`
+- `same_value_different_representation`
+- `not_a_contradiction`
+- `missing_evidence`
+- `extraction_misread`
+- `code_path_not_applicable`
+- `duplicate`
+- `severity_too_high`
+- `severity_too_low`
+- `other`
+
+## Finalization rules
+
+- All blocking review items must have a valid decision before finalization.
+- Confirmed findings become final `validated_issues`.
+- Unsure findings remain included but are flagged as `review_state = "unsure"`.
+- Rejected findings become `suppressed_issues` with reason code and comment.
+- Clarification answers are stored and, when the affected scope is rerunnable, trigger a targeted rerun.
+- Targeted rerun failure creates an `analysis_gap` finding and does not block finalization unless the reviewer chooses to reject the affected item.
+- RFIs are drafted only for final kept issues.
+
+## Feedback labels
+
+Every decision emits a label artifact for metrics:
+
+```json
+{
+  "review_item_id": "finding:AGENT-0007",
+  "job_id": "abc123",
+  "pipeline_mode": "agent",
+  "source_stage": "conflict",
+  "category": "elevation_disagreement",
+  "severity": "high",
+  "confidence": "medium",
+  "decision": "reject",
+  "reason_code": "same_value_different_representation",
+  "location": "Room 204 / Level 2",
+  "disciplines": ["Architectural", "Mechanical"],
+  "sheets": ["A2.1", "M2.1"],
+  "drawing_type": "floor_plan",
+  "models_used": ["google/gemini-2.5-pro"],
+  "created_at": "2026-07-28T12:00:00Z"
+}
+```
+
+Default aggregate metrics exclude `source_text`, images, raw sheet content, and reviewer free-text comments.
+
+## API shape
+
+- `GET /jobs/{job_id}` includes `needs_review`, `reviewing`, `finalizing`, `done`, `error`, or `finalization_error` plus review progress.
+- `GET /jobs/{job_id}/review` returns `{ "queue": [...], "progress": {...} }`.
+- `POST /jobs/{job_id}/review-decisions` saves one or more decisions.
+- `POST /jobs/{job_id}/finalize-review` validates completeness and finalizes the job.
+
+## Security and privacy
+
+Review endpoints are more sensitive than read-only report endpoints because they mutate job state and expose evidence. Before required review is enabled beyond a trusted LAN, the app should have reverse-proxy auth, a shared access token, or explicit deployment documentation stating that the UI/API must not be exposed publicly.
+
+Review artifacts stay job-local by default. Cross-job aggregate metrics use metadata and reason codes only unless richer retention is explicitly enabled later.
+
+## Testing strategy
+
+Tests must not require PDFs, LLMs, OpenRouter, or network access.
+
+Cover:
+
+- required-review trigger policy,
+- review queue construction,
+- decision validation and reason codes,
+- finalization behavior for confirm/reject/unsure/clarification,
+- restart recovery from review artifacts,
+- targeted rerun failure degradation,
+- metrics redaction,
+- API state transitions,
+- email flow blocking until finalization.
+
+## Rollout
+
+- Classic mode is unchanged.
+- Agent web jobs default to required human review.
+- CLI supports an explicit bypass flag, `--no-review`, for tuning/debug runs.
+- Review state and decisions are always written to job artifacts.
+- Aggregate feedback is metadata-only by default.
+
+## Acceptance criteria
+
+- An Agent web job cannot reach `done` or send the final email while required review items are undecided.
+- Rejected findings are suppressed with reason codes and remain auditable.
+- Review progress survives server restart.
+- Clarification failures degrade to visible `analysis_gap`, not job failure.
+- Aggregate feedback contains no raw drawing text/images by default.
+- New tests cover the review gate without requiring LLM calls.
