# Normal Camera Unused Pool Extension 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:** Extend the no-generation normal-camera atlas prep system across larger unused image pools, starting with the uncovered `reverse cowgirl` folder.

**Architecture:** Keep the folder inventory and curated variant catalog as the source of truth. Add read-only review/backlog builders to `normal_camera_atlas_prep.py`, write review artifacts under `ab_batches/normal_camera/`, then add selected catalog variants only when review evidence supports stable non-POV camera/pose families.

**Tech Stack:** Python standard library, Pillow for optional contact-sheet image output, existing JSON catalogs, existing `tools/prompt_smoke.py` smoke harness.

### Task 1: Add Unused-Pool Review Artifact Tests

**Files:**
- Modify: `tools/prompt_smoke.py`
- Test: `python tools/prompt_smoke.py --case normal_camera_unused_pool_review_artifacts --quiet`

- [ ] **Step 1: Add failing smoke coverage**

Add a smoke case that imports `normal_camera_atlas_prep`, calls `build_unused_pool_backlog(limit=5)`, `build_review_manifest("reverse cowgirl", page_size=40)`, and `build_contact_sheet_html("reverse cowgirl", page_size=40)`, then asserts:

```python
backlog = prep_module.build_unused_pool_backlog(limit=5)
_expect(backlog.get("schema") == "sxcp_normal_camera_unused_pool_backlog_v1", "Normal camera unused-pool backlog schema changed")
_expect(backlog.get("no_generation") is True, "Normal camera unused-pool backlog must stay no-generation")
_expect((backlog.get("folders") or [])[0].get("folder") == "reverse cowgirl", "Reverse cowgirl should be the first unused-pool tranche")

manifest = prep_module.build_review_manifest("reverse cowgirl", page_size=40)
_expect(manifest.get("schema") == "sxcp_normal_camera_review_manifest_v1", "Normal camera review manifest schema changed")
_expect(manifest.get("folder") == "reverse cowgirl", "Review manifest should target reverse cowgirl")
_expect(manifest.get("image_count") == 240, "Reverse cowgirl review should cover all 240 JPGs")
_expect(len(manifest.get("contact_sheet_pages") or []) == 6, "Reverse cowgirl review should be paged at 40 images per sheet")
_expect("back_view" in manifest.get("review_bucket_values", {}), "Review buckets lost back-view routing")

html = prep_module.build_contact_sheet_html("reverse cowgirl", page_size=40)
_expect("reverse cowgirl/0001.jpg" in html, "Contact sheet lost first reverse-cowgirl image")
_expect("data-review-bucket" in html, "Contact sheet should expose review buckets")
```

- [ ] **Step 2: Register the new smoke case**

Add `("normal_camera_unused_pool_review_artifacts", smoke_normal_camera_unused_pool_review_artifacts)` after the existing normal-camera prep smoke case.

- [ ] **Step 3: Verify the test fails**

Run:

```bash
python tools/prompt_smoke.py --case normal_camera_unused_pool_review_artifacts --quiet
```

Expected: failure because `build_unused_pool_backlog`, `build_review_manifest`, and `build_contact_sheet_html` do not exist yet.

### Task 2: Implement Backlog and Review Manifest Builders

**Files:**
- Modify: `normal_camera_atlas_prep.py`
- Test: `python tools/prompt_smoke.py --case normal_camera_unused_pool_review_artifacts --quiet`

- [ ] **Step 1: Add schemas and review buckets**

Add constants:

```python
UNUSED_POOL_BACKLOG_SCHEMA = "sxcp_normal_camera_unused_pool_backlog_v1"
REVIEW_MANIFEST_SCHEMA = "sxcp_normal_camera_review_manifest_v1"
DEFAULT_REVIEW_DIR = DEFAULT_OUTPUT_DIR / "review"
REVIEW_BUCKET_VALUES = {
    "back_view": "Rear-facing normal-camera view where back/hips face camera.",
    "back_three_quarter": "Rear-offset normal-camera view with enough side/torso context.",
    "side_view": "Profile or near-profile lateral view with the body/action axis across frame.",
    "front_view": "Front-facing normal-camera view where the contact plane faces camera.",
    "front_three_quarter": "Front-offset normal-camera view.",
    "top_or_low_special": "Overhead, high-downward, low-angle, or under-view special camera.",
    "reject_or_unclear": "POV-like, mismatched, unclear, duplicate-only, or too mixed for cue drafting.",
}
```

- [ ] **Step 2: Add helper functions**

Add helpers to compute selected-reference coverage and page full-folder images:

```python
def _natural_sort_key(text: str) -> list[int | str]:
    return [int(part) if part.isdigit() else part.lower() for part in re.split(r"(\\d+)", text)]

def _atlas_folder_rows() -> list[dict[str, Any]]:
    return list(load_atlas().get("folders") or [])

def _variant_reference_map() -> dict[str, set[str]]:
    refs_by_folder: dict[str, set[str]] = {}
    for variant in load_variants().get("variants") or []:
        for ref in _reference_images(variant):
            folder = ref.rsplit("/", 1)[0]
            refs_by_folder.setdefault(folder, set()).add(ref)
    return refs_by_folder
```

- [ ] **Step 3: Implement backlog builder**

Implement `build_unused_pool_backlog(limit: int | None = None)` so it ranks non-empty folders by unselected image count, with fields `folder`, `image_count`, `selected_reference_count`, `remaining_image_count`, `covered_by_variants`, `camera_view`, `action_family`, `catalog_status`, and `suggested_action`.

- [ ] **Step 4: Implement review manifest and HTML builders**

Implement `build_review_manifest(folder_name: str, page_size: int = 40)` and `build_contact_sheet_html(folder_name: str, page_size: int = 40)` so `reverse cowgirl` produces six pages and exposes review buckets without classifying any image as truth.

- [ ] **Step 5: Verify green**

Run:

```bash
python tools/prompt_smoke.py --case normal_camera_unused_pool_review_artifacts --quiet
```

Expected: `OK: smoke passed (1 cases).`

### Task 3: Write Review Artifacts

**Files:**
- Modify: `normal_camera_atlas_prep.py`
- Create: `ab_batches/normal_camera/normal_camera_unused_pool_backlog.json`
- Create: `ab_batches/normal_camera/review/reverse_cowgirl_review_manifest.json`
- Create: `ab_batches/normal_camera/review/reverse_cowgirl_contact_sheet.html`
- Test: `python -m normal_camera_atlas_prep --write-artifacts --output-dir ab_batches/normal_camera`

- [ ] **Step 1: Extend artifact writing**

Update `write_artifacts()` to include the unused-pool backlog and reverse-cowgirl review artifacts. Keep existing artifact names stable.

- [ ] **Step 2: Regenerate artifacts**

Run:

```bash
python -m normal_camera_atlas_prep --write-artifacts --output-dir ab_batches/normal_camera
```

Expected: output includes the four existing artifacts plus `unused_pool_backlog`, `reverse_cowgirl_review_manifest`, and `reverse_cowgirl_contact_sheet`.

- [ ] **Step 3: Verify prep smoke**

Run:

```bash
python tools/prompt_smoke.py --case normal_camera_atlas_prep_artifacts --case normal_camera_unused_pool_review_artifacts --quiet
```

Expected: `OK: smoke passed (2 cases).`

### Task 4: Add Reverse-Cowgirl Catalog Source Pool

**Files:**
- Modify: `categories/normal_camera_variants.json`
- Modify: `tools/prompt_smoke.py`
- Test: `python tools/prompt_smoke.py --case normal_camera_atlas_catalog --quiet`

- [ ] **Step 1: Add failing catalog expectation**

Extend `required_variants` in `smoke_normal_camera_atlas_catalog()` with `normal_reverse_cowgirl_mixed_camera_folder_pool`.

- [ ] **Step 2: Verify red**

Run:

```bash
python tools/prompt_smoke.py --case normal_camera_atlas_catalog --quiet
```

Expected: failure because the mixed source-pool variant does not exist.

- [ ] **Step 3: Add the source-pool variant**

Add a `needs_samples` variant after the existing labeled reverse-cowgirl variants:

```json
{
  "key": "normal_reverse_cowgirl_mixed_camera_folder_pool",
  "family": "reverse_cowgirl",
  "status": "needs_samples",
  "atlas_folders": ["reverse cowgirl"],
  "camera_view": "mixed_or_unspecified",
  "action_family": "reverse_cowgirl",
  "canonical_geometry": "Large reverse-cowgirl source pool with normal-camera examples but no single locked camera view until contact-sheet review selects stable subsets.",
  "prompt_cues": [
    "reverse cowgirl normal-camera source pool",
    "select a repeated camera family before cue drafting",
    "use contact-sheet evidence before fixed-seed testing"
  ],
  "avoid_cues": [
    "using the full mixed folder as one locked camera preset",
    "POV reverse-cowgirl wording",
    "inventing camera cues from the folder label alone"
  ],
  "reference_images": [
    "reverse cowgirl/0001.jpg",
    "reverse cowgirl/288.jpg",
    "reverse cowgirl/82.jpg"
  ],
  "generator_hook": {
    "module": "future normal-camera routing; likely camera_config.py / row_camera.py / krea_format_route.py",
    "route_terms": ["reverse cowgirl", "mixed camera source pool"],
    "notes": "Future hook only. This catalog does not change generator defaults, prompt routes, formatters, eval logs, or POV workflow files."
  },
  "pre_ab_notes": "Added as the first large unused-pool review tranche. The full 240-image folder is a cue-expansion pool, not a prompt-ready route; split selected-reference subvariants only after contact-sheet evidence shows repeated non-POV camera geometry.",
  "folder_pool": true,
  "visual_review": {
    "reviewed_at": "2026-07-02",
    "scope": "Paged contact-sheet review scaffold covering 240 JPGs across atlas_folders plus representative references.",
    "decision": "added_as_large_unused_pool_review_tranche",
    "notes": "Folder is now tracked for review; selected-reference subvariants should be added only from repeated camera/pose families identified in the contact sheet."
  }
}
```

- [ ] **Step 4: Update inventory counts**

Increment `variant_count` and `needs_samples`, increment `covered_non_empty_folder_count`, decrement `uncovered_non_empty_folder_count`, and remove `reverse cowgirl` from `uncovered_non_empty_folders`.

- [ ] **Step 5: Verify green**

Run:

```bash
python tools/prompt_smoke.py --case normal_camera_atlas_catalog --quiet
```

Expected: `OK: smoke passed (1 cases).`

### Task 5: Document and Regenerate Prep Outputs

**Files:**
- Modify: `docs/normal-camera-atlas.md`
- Modify: `ab_batches/normal_camera/normal_camera_priority_plan.json`
- Modify: `ab_batches/normal_camera/normal_camera_prompt_cue_batch.json`
- Modify: `ab_batches/normal_camera/normal_camera_score_sheet.json`
- Test: `python tools/prompt_smoke.py --case normal_camera_atlas_catalog --case normal_camera_atlas_prep_artifacts --case normal_camera_unused_pool_review_artifacts --quiet`

- [ ] **Step 1: Update docs**

Document that the unused-pool extension starts with `reverse cowgirl`, adds `normal_camera_unused_pool_backlog.json`, and keeps full mixed folders out of `pre_ab_candidate` until selected-reference subvariants exist.

- [ ] **Step 2: Regenerate artifacts**

Run:

```bash
python -m normal_camera_atlas_prep --write-artifacts --output-dir ab_batches/normal_camera
```

- [ ] **Step 3: Verify focused smoke**

Run:

```bash
python tools/prompt_smoke.py --case normal_camera_atlas_catalog --case normal_camera_atlas_prep_artifacts --case normal_camera_unused_pool_review_artifacts --quiet
```

Expected: `OK: smoke passed (3 cases).`

### Task 6: Visual Split Follow-Up

**Files:**
- Modify later: `categories/normal_camera_variants.json`
- Modify later: `docs/normal-camera-atlas.md`
- Test later: focused smoke cases above

- [ ] **Step 1: Review the contact sheet**

Open `ab_batches/normal_camera/review/reverse_cowgirl_contact_sheet.html` or generated page images, classify repeated non-POV camera/pose families, and record selected image paths.

- [ ] **Step 2: Add selected-reference subvariants only when evidence is stable**

For each repeated family, add a subvariant with `source_variant: "normal_reverse_cowgirl_mixed_camera_folder_pool"`, `subset_selection.type: "review_selected_reference_images"`, positive-only cue sentences, and selected `reference_images`.

- [ ] **Step 3: Leave weak groups as `needs_samples`**

Do not promote one-off frames, POV-like frames, or visually mixed groups. Keep them in source-pool notes or review buckets until more evidence exists.
