Telemetry must **never** abort the primary flow. + +**Fixed to:** +```python +except Exception: # catch ALL, never abort + logger.warning("failed to write tile") +``` + +Tests passed because test environment had healthy OpenCV. The bug only surfaces in edge cases (missing codec, corrupted install, file system full on unknown error).

Narrow catches (`OSError`) assume the stdlib exception hierarchy is stable; it's not (NumPy, OpenCV, Pillow each have their own exception trees). + +2. **TDD locks behavior, but doesn't catch all bugs.** Tests verify the happy path and specified error cases. They don't enumerate all possible exception types the third-party libs might throw. Code review with domain knowledge (knowing `cv2.error` exists) caught what tests missed. + +3. **Symmetry matters.** Because `RecaptchaSolver` and `AsyncRecaptchaSolver` are **parallel implementations, not wrappers**, every logic change must land in both. Phase 1 wiring + Phase 2 hooks went into both without friction — the pattern worked. + +4. **Hook placement at the detector level (DRY).** The detector already crops tiles; asking handlers to re-crop them is waste.

We built a collection and annotation workflow, but execution depends on human time. This is the "brutal honesty" stated in the plan: "no shortcuts" for data quality. + +The MPS assumption was overly pessimistic. Mac's machine learning ecosystem includes GPU support via MPS; we didn't check initially because the focus was rCAPTCHA solving, not training.

Keep `FOLDER_ORDER` and the model's `names` aligned. + +## Tier B: custom 4x4 detection model (COCO gap) + +The bundled COCO model (`yolo12x.pt`) lacks 7 reCAPTCHA classes — bridges, chimneys, +crosswalks, mountains or hills, palm trees, stairs, tractors. For those, 4x4 currently uses +the **per-cell classification fallback** (`SquareCaptchaHandler._classify_cells_fallback`). +Tier B trains a dedicated **detection** model on these classes (better for one large object +spanning cells) via a separate bbox pipeline. The 4x4 handler runs a 3-tier priority: +COCO detection → custom detection (if a model is loaded) → per-cell fallback. + +> Detection needs **full-image + bounding-box** data, which the per-cell classification +> flywheel does NOT produce. Tier B has its own collection + annotation pipeline. + +1. **Collect full images** — enable collection (`collect_data=True`); each 4x4 solve saves + the whole image to `collected/full/` + `collected/full/metadata.jsonl` via + `DataCollector.record_challenge_image`. Drive many solves with the loop helper: + `python training/collect.py --runs 200 --delay 3` (reports `full-4x4` / `tiles` counts). +2. **Annotate (cell → bbox)** — produces `annotations.jsonl`. Two ways: + - **Manual:** `python training/annotate_detection_cli.py --collected-dir collected/full + --open` — pick class + cells (1..16) per image. + - **Auto (CapMonster, ~$0.04/1000):** `export CAPMONSTER_API_KEY=... && + python training/auto_annotate_capmonster.py --collected-dir collected/full` — sends each + 4x4 image to CapMonster's image mode (`ComplexImageTask`/`recaptcha`), which returns the + cells; cheaply bypasses manual labeling. Only the 7 detection classes are labeled + (others skipped). Note: this is CapMonster's own classifier output — high but not perfect + accuracy; spot-check before training. (cap.guru can't do this — token mode only.) + Each selected cell becomes one YOLO box (cell-level weak supervision). +3. **Build detection dataset** — `python training/prepare_detection_dataset.py --annotations + collected/full/annotations.jsonl --dataset training/detection_dataset`: emits + `images/`, `labels/`, `data.yaml` (names = `class_mapping.DETECTION_CLASSES`). +4. **Train (CUDA / Apple-Silicon MPS / CPU)** — `python training/train_detection.py --data + training/detection_dataset/data.yaml` (auto device; base `yolo11x.pt`, task detect). The + Tier B set is small, so an Apple Silicon Mac (`--device mps --no-amp`) is a fine choice — + no dataset upload. Use a cloud CUDA GPU if it grows large. (Phase 3: `train_detection.py` + reuses `device_utils.resolve_device` + the `--amp/--no-amp` flag, like `train.py`.) +5. **Export + SHA256 + card + publish** — `export_onnx.py --weights .../best.pt` (needs the + `onnx` package — `pip install -e ".[dev]"`), `compute_sha256.py best.onnx`, + `write_model_card.py --onnx best.onnx --task detect ...`, then set + `YOLODetector.CUSTOM_DETECTION_MODEL_URL` + `CUSTOM_DETECTION_SHA256`, upload to Hugging Face. +6. **Enable at runtime** — `SolverConfig(custom_detection_model_path="...onnx")`. With no + path set (default) the runtime is unchanged (COCO + per-cell fallback). + +> **Contract:** `types.CUSTOM_DETECTION_CLASSES` (runtime) MUST equal +> `training/class_mapping.DETECTION_CLASSES` (training) — a test enforces this. A mismatch +> maps detections to the wrong class. + +## Collection findings (Google demo, observed) + +Empirical notes from running `collect.py` against the Google reCAPTCHA demo: + +- **Throughput:** ~1 solve / 4–6 min (each run re-inits a fresh solver + reloads models). + ~5–10 full 4x4 images per run (one solve cycles through several 4x4 reloads). +- **Class skew:** the demo overwhelmingly serves **COCO** classes (motorcycles, bicycles, + buses, traffic lights). Of the 7 detection-gap classes, only **stairs** (and a few + **crosswalks**) appear with any frequency; bridges/chimneys/mountains/palm trees/tractors + were essentially **never served**. Gap-class yield ≈ 10% of collected images. +- **Rate limiting:** Google starts blocking after ~15–20 consecutive runs — symptoms are + `solved` stalling, rising `failed`, and `.rc-imageselect-payload` element-not-found errors. + A break (hours) resets it. Keep `--delay` ≥ 3s and stop on a stall+failures signal. +- **Implication:** the demo alone cannot supply a balanced 7-class detection set. For the + missing classes, collect from **diverse real targets** (varied sites/sitekeys), not just + the demo. The demo is fine for **stairs** (and validating the pipeline end-to-end). +- **Sample run:** ~103 full 4x4 images collected over ~20 runs → 16 stairs + 2 crosswalks + gap-class; rest COCO.
