 Before you contribute a new feature, consider submitting an Issue to discuss the feature so the community can weigh in and assist.
 
+### API Design Principles
+
+Supervision APIs should remain generic, composable, and predictable across model families. Before adding a new integration, annotator option, or data conversion method, check the existing `sv.Detections`, `sv.KeyPoints`, and annotator patterns and follow these principles:
+
+1. **Model integrations normalize raw external outputs into existing Supervision containers.** Use `sv.Detections` for detection, segmentation, and other instance-level predictions that include boxes, masks, class ids, confidence scores, or extra per-instance fields. Use `sv.KeyPoints` for standalone keypoint or pose predictions when keypoints exist independently of detection boxes (e.g. pure pose estimation, landmark detection on pre-cropped images). Use `Detections.keypoints` when keypoints are always co-incident with boxes from the same model — the field stores an `(n, K, 2)` or `(n, K, 3)` array where the optional third channel is per-point confidence in `[0, 1]`.
+2. **Do not add a `from_<model>` method when the model already returns a Supervision object.** `from_*` methods are for converting raw outputs from external packages such as Ultralytics, Transformers, Inference, or MediaPipe. If a model's `predict()` method already returns `sv.Detections`, keep that result type and store additional structured payloads in `detections.data` or `detections.metadata` using documented keys.
+3. **Annotators render data; filtering and visibility are container state.** Filtering by confidence, class id, tracker id, geometry, or custom data should happen before annotation through the container slicing APIs, for example `detections[detections.confidence > 0.7]` or `key_points[key_points.confidence > 0.5]`. Per-point presentation state, such as a `KeyPoints.visible` mask, may live on the container and be honored consistently by annotators.
+4. **Annotator constructor arguments should describe visual presentation, not model-quality gates.** Use constructor arguments for color, thickness, opacity, text, position, style, and generic visualization parameters such as sigma levels. Annotators may skip invalid geometry defensively, including missing points, zero-area boxes, non-finite coordinates, or points marked invisible on the container. They should not introduce confidence thresholds or model-specific quality gates as rendering options.

+Every docstring should include a usage example. When the example only uses `supervision`, NumPy, and the standard library — no optional extras, no external files or network access — strongly prefer `>>>` doctest format so it is automatically verified by the test suite. See [Doctests](#doctests) below for syntax guidance and for when fenced ```` ```python ```` blocks are appropriate instead.
+
 ### Type checking
 
-Currently, there is no systematic type checking with mypy implemented in the project. This is a known limitation that may be addressed in future updates.
+Type hints are required on all new code. mypy is enforced by the pre-commit hook configured in `.pre-commit-config.yaml` — your PR will fail CI if mypy reports errors.
+
+### Readability
+
+Avoid multi-branch conditional expressions inside function or constructor arguments. If an argument needs more than a simple `a if condition else b`, assign it to a named local variable before the call.
+
+### Performance
+
+- Avoid unnecessary copies of NumPy arrays.
+- Prefer vectorized operations over Python loops in hot paths.
+- Lazy-import heavy framework dependencies (`torch`, `transformers`, `ultralytics`) inside the function that needs them — never at module top level.
+
+### Deprecation policy
+
+**Minimum window**: deprecated APIs must remain for at least **3 minor releases** before removal. Example: deprecated in `0.29.0` → removed in `0.32.0`.
+
+Use the appropriate mechanism depending on what is being deprecated:
+
+- **Module-level alias**: `supervision.utils.internal.warn_deprecated` in the deprecated module's `__init__.py`
+- **Renamed parameter**: `supervision.utils.internal.deprecated_parameter` decorator
+- **Public function, method, or class**: `@deprecated` from `pydeprecate`
+
+Always specify both the deprecation version and the planned removal version in the message or decorator arguments.
+
+### Deprecated module aliases
+
+`supervision.keypoint` is deprecated since `0.27.0` and will be removed in `0.30.0`. Always import from `supervision.key_points`:

+### Test Structure
+
+Follow **Arrange-Act-Assert (AAA)**: one setup block, one action, one assertion group per test. Never put two independent actions in the same test.
+
+**Class grouping:** Group related tests into a class. The class name carries the unit under test; method names describe the expected outcome only — not the mechanism.
+
+```python
+class TestDetectionsWithNms:
+    def test_keeps_highest_confidence_detection(self): ...
+    def test_suppresses_lower_score_when_overlap_exceeds_threshold(self): ...
+    def test_raises_when_confidence_missing(self): ...
+```
+
+**Parametrize aggressively:** Three or more structurally identical tests should become a single `@pytest.mark.parametrize` case. Use `pytest.param(..., id="slug")` per case — not `ids=[...]` on the decorator — so the ID stays co-located with its arguments and survives reordering.
+
+```python
+@pytest.mark.parametrize(
+    ("overlap_metric", "expected_keep"),
+    [
+        pytest.param(OverlapMetric.IOU, [True, True], id="iou-keeps-both"),
+        pytest.param(OverlapMetric.IOS, [True, False], id="ios-suppresses-small"),
+    ],
+)
+def test_overlap_metric_determines_suppression(
+    overlap_metric: OverlapMetric, expected_keep: list[bool]
+) -> None:
+    """Small box inside large: IOU keeps both; IOS suppresses small."""
+    ...
+```
+
+**Docstrings:** Every test function/method requires at minimum a one-line docstring (within the project line length configured in `pyproject.toml`). Describe the scenario, not the implementation.
+
+### Doctests
+
+**Guidance:** when an example uses only `supervision`, NumPy, and the standard library — no optional extras (e.g. no `--extra metrics` packages), no external files, no network, no devices — prefer `>>>` doctest format so it is automatically verified by the test suite. Fenced ```` ```python ```` blocks are appropriate when the example cannot reasonably be executed (e.g. loading a third-party model, reading a video file) or when the primary purpose is demonstrating error/exception behaviour rather than return values.
+
+Doctests run automatically as part of the test suite via `--doctest-modules` in `pyproject.toml`. The `ELLIPSIS` and `NORMALIZE_WHITESPACE` flags are enabled globally, so `...` matches any output fragment and minor whitespace differences are ignored.
+
+```bash
+uv run pytest --doctest-modules src/
+```
+
+**Writing a doctest**
+
+Use the `Example:` section of a Google-style docstring. Prefix each input line with `>>>` and each continuation line with `...`. Place expected output immediately after the last input line with no blank line between them.
+
+```python
+def clip_boxes(xyxy: np.ndarray, resolution_wh: tuple) -> np.ndarray:
+    """Clip bounding boxes to frame boundaries.
+
+    Args:
+        xyxy: Box coordinates as (N, 4) float array.
+        resolution_wh: Frame size as (width, height).
+
+    Returns:
+        Clipped boxes as (N, 4) float array.
+
+    Example:
+        >>> import numpy as np
+        >>> import supervision as sv
+        >>> boxes = np.array([[-10, -5, 120, 80]], dtype=np.float32)
+        >>> sv.clip_boxes(boxes, resolution_wh=(100, 60))
+        array([[ 0.,  0., 100.,  60.]], dtype=float32)
+    """
+```
+
+### Key rules
+
+- **Single-line expression** — write the repr as expected output: `>>> len(result)` → `1`
+- **Multi-line statement** — use `...` continuation: `>>> arr = np.array([` / `...     [1, 2],` / `... ])`
+- **Print output** — write the printed string as expected output (no quotes).
+- **`None` return** — no output line needed (suppress with assignment or `_ =`).
+- **Large/variable arrays** — use `ELLIPSIS`: `array([...])` matches any content.
+- **`# doctest: +SKIP`** — use only as a last resort for genuinely non-runnable lines (e.g. a GPU-only call inside an otherwise runnable example). Prefer splitting the example into two blocks instead.
+
+Fenced ```` ```python ```` blocks remain appropriate for:
+
+- Examples that import optional extras (`supervision[metrics]`, `torch`, `ultralytics`).
+- Examples that read files, capture video, or require a running service.
+- Illustrative pseudocode that is intentionally incomplete.

----
 
 ## 1. Before You Code
 
-- Read the task/issue thoroughly before acting.
+- Read the task thoroughly; group clarifications into one ask.
-- Identify missing information; ask **one targeted clarification question** if needed.
+- Outline a plan before making changes.
-- Outline a step-by-step plan before making changes.
+- Check whether the feature already exists under a different name.
-- Check whether the feature or fix already exists under a different name.
+- Confirm alignment with `src/supervision/` architecture.
-- Confirm alignment with the repository's architecture (`src/supervision/`).

+## 2. Repository Architecture
 
-All work must follow the conventions of the `supervision` library
+**Package root**: `src/supervision/` — all library code. **Tests**: `tests/` — mirrors `src/supervision/`. **Public API**: `src/supervision/__init__.py`.
-(see [CONTRIBUTING.md](.github/CONTRIBUTING.md) for full details).
 
-### Branching & Commits
+```

-- Branch from `develop` using prefixes: `feat/`, `fix/`, `docs/`, `refactor/`, `test/`, `chore/`.
+### Key design patterns
-- Use **conventional commits**: `feat:`, `fix:`, `docs:`, `refactor:`, `perf:`, `test:`, `chore:`.
-- PRs must target the `develop` branch.
 
-### Code Style
+- **`Detections` is the lingua franca** — every connector, tracker, and annotator speaks `Detections`. New connector = `@classmethod from_<framework>(cls, result) -> Detections`.
+- **Annotators are composable** — receive `scene` (BGR `np.ndarray`) + `detections`, return annotated copy.
+- **`data` dict extensibility** — per-detection metadata in `detections.data` as `np.ndarray` aligned with `xyxy`. Keys are constants from `config.py`.
+- **Vectorized throughout** — NumPy arrays, no Python loops in hot paths. Never write `for det in detections`.
+- **Lazy-import heavy deps** — `torch`, `transformers`, `ultralytics` must be imported inside the function that needs them, never at module top level.
 
-- **Formatting and linting** are enforced by **pre-commit**.
+______________________________________________________________________
-    The hook chain typically includes: ruff-check, ruff-format, codespell, mdformat,
-    prettier, pyproject-fmt, and standard pre-commit-hooks (trailing whitespace, YAML, TOML, etc.).
-- **Type hints**: required on all new code. Type checking with mypy is encouraged but not
-    currently enforced systematically by pre-commit; see [.github/CONTRIBUTING.md](.github/CONTRIBUTING.md)
-    for the latest type-checking expectations.
-- **Docstrings**: Google Python docstring style. Required for all new functions and classes.
-    Docstrings should include usage examples demonstrating the function with primitive values
-    so they serve as runnable documentation.
 
-### API Consistency
+## 3. Agent-Critical Rules
 
-- Follow existing naming patterns.
+These supplement [CONTRIBUTING.md](.github/CONTRIBUTING.md) — covering gaps or agent-specific failure modes.
-- Maintain backward compatibility unless explicitly allowed.
-- Prefer functional utilities over complex classes unless justified.
 
-### Performance
+**Doc headings**: `###` max in docstrings and docs. `####` renders identically to bold in mkdocs — use `**bold**` instead.
 
-- Avoid unnecessary copies of NumPy arrays.
+**Type hints**: required on all new code. mypy is enforced by pre-commit (`.pre-commit-config.yaml`).
-- Prefer vectorized operations over Python loops in hot paths.
-- Use OpenCV operations efficiently.
 
----
+**Function docstrings**: every new or modified function, including private helpers and tests, must have a succinct docstring explaining its purpose. Put function-level why/what/how context inside the function docstring, not in a comment before the function. Public APIs still require the full Google-style structure described below.
 
-## 3. Implementing Features
+**Readable argument lists**: do not put multi-branch conditional expressions inside function or constructor arguments. If an argument needs more than a simple `a if condition else b`, assign it to a named local variable before the call.
 
-- Provide a minimal, clean implementation.
+**Inline comments**: write code so the intent is clear from names, small helpers, and straightforward control flow. For non-trivial logic inside a function that still needs context, add concise inline comments explaining why the code exists, what invariant it protects, and how the tricky part works. Do not put comments before functions; use the function docstring instead. Do not comment obvious assignments, mechanical plumbing, lint-only changes, typing-only changes, or pure docs edits.
-- Include type hints and Google-style docstrings with usage examples.
-- All new functionality must be covered with tests, including edge cases.
-- Add or update documentation (docstrings + mkdocs entries if applicable).
-- Ensure compatibility with core dependencies: NumPy, OpenCV, SciPy.
 
----
+**Doctest determinism** — output must be reproducible across platforms:
 
-## 4. Fixing Bugs
+- Use `# doctest: +ELLIPSIS` for floats that vary by platform.
+- Seed any RNG before calling it.
+- Never assert `dict` or `set` iteration order.
+- No network or filesystem access outside `supervision/assets/`.
 
-1. Reproduce and understand the root cause.
+**⚠ Test structure** — agents frequently fail here; read [CONTRIBUTING.md §Tests](.github/CONTRIBUTING.md#-tests) carefully: AAA structure, class grouping, parametrize with `pytest.param(..., id="slug")`, one-line docstring per test.
-2. Write a test that reproduces the bug (it should fail before the fix).
-3. Apply a minimal, targeted fix.
-4. Verify the test passes and no other components break.
 
----
+For branching, commit, code style, and API design conventions see [CONTRIBUTING.md](.github/CONTRIBUTING.md).
 
-## 5. Refactoring
+______________________________________________________________________
 
-- Preserve behavior and API stability.
+## 4. Deprecated Module Aliases
-- Improve readability or performance.
-- Reduce duplication.
-- Avoid large, sweeping refactors unless explicitly requested.
 
----
+`supervision.keypoint` deprecated since `0.27.0`, removed in `0.31.0`. Always import from `supervision.key_points`, not `supervision.keypoint`.
 
-## 6. Before You Commit
+______________________________________________________________________
 
-Always run these before committing:
+## 5. Deprecating APIs
+
+**Minimum window**: deprecated APIs must remain for at least **3 minor releases** before removal. Example: deprecated in `0.29.0` → removed in `0.32.0`.
+
+- Module-level: `supervision.utils.internal.warn_deprecated` in the deprecated module's own `__init__.py`
+- Parameter renamed (old→new): `supervision.utils.internal.deprecated_parameter` decorator
+- Public function, method, or class: `@deprecated` from `pydeprecate`
+
+Always name the version introduced and the removal version:
+
+```python
+warn_deprecated("'foo' deprecated in `0.29.0`, removed in `0.32.0`. Use 'bar'.")
+```
+
+______________________________________________________________________
+
+## 6. Implementing Features
+
+- Minimal implementation; type hints and Google docstrings with usage examples.
+- Tests covering new functionality and edge cases (see [CONTRIBUTING.md §Tests](.github/CONTRIBUTING.md#-tests)).
+- Update docstrings and mkdocs entries as needed.
+- Update [docs/changelog.md](docs/changelog.md) for every functional change or bug fix, including user-visible behavior changes. Skip changelog entries for lint-only, type-only, formatting-only, and pure documentation-only changes.
+
+**Extending `Detections`**: store metadata in `detections.data` as `np.ndarray` aligned with `xyxy`; define the key as a constant in `config.py` (e.g. `CLASS_NAME_DATA_FIELD`, `ORIENTED_BOX_COORDINATES`).
+
+**New model connector** (`detection/core.py`):
+
+```python
+@classmethod
+def from_myframework(cls, result) -> "Detections":
+    import myframework  # noqa: F401 — lazy import
+
+    xyxy = ...  # (N, 4)
+    return cls(
+        xyxy=xyxy,
+        confidence=...,
+        class_id=...,
+        data={CLASS_NAME_DATA_FIELD: np.array([...])},
+    )
+```
+
+VLM connectors go in `detection/vlm.py`, not `core.py`.
+
+______________________________________________________________________
+
+## 7. Bugs & Refactoring
+
+**Bugs**: reproduce → write failing test → minimal fix → verify no regressions.
+
+**Refactoring**: preserve behavior and API; reduce duplication; avoid sweeping changes unless requested; apply §5 deprecation when removing public API.
+
+______________________________________________________________________
+
+## 8. Before You Commit
 
 ```bash
 uv run pytest --cov=supervision
 uv run pre-commit run --all-files
 ```
 
-- All pre-commit hooks must pass (formatting, linting, type checking, spell check, etc.).
+Capture a baseline before changes to avoid introducing new failures:
-- All tests must pass before opening a PR. Note: some existing tests in the repo may
+
-    already be failing — your changes must not introduce new failures.
+```bash
-- Fix any issues reported and re-run until clean.
+STASH_BEFORE=$(git rev-parse refs/stash 2>/dev/null)
+git stash push --include-untracked
+uv run pytest -q 2>&1 | tee /tmp/baseline.txt
+[ "$(git rev-parse refs/stash 2>/dev/null)" != "$STASH_BEFORE" ] && git stash pop
+uv run pytest -q 2>&1 | tee /tmp/after.txt
+diff /tmp/baseline.txt /tmp/after.txt
+```
+
+Any test passing in baseline but failing after = blocker.

 Supervision was designed to be model agnostic. Just plug in any classification, detection, or segmentation model. For your convenience, we have created [connectors](https://supervision.roboflow.com/latest/detection/core/#detections) for the most popular libraries like Ultralytics, Transformers, MMDetection, or Inference. Other integrations, like `rfdetr`, already return `sv.Detections` directly.

For dense masks, provide a boolean array of shape `(N, H, W)` where `(H, W)` matches the image height and width (it also accepts `sv.CompactMask`). If your model returns framework-specific results, convert them to `sv.Detections` first, for example with `sv.Detections.from_ultralytics(...)` or `sv.Detections.from_inference(...)`.

+description: Migrate Supervision installations after OpenCV becomes an ambient optional backend: use the included fallback by default or select one compatible OpenCV wheel for your application.
+date_modified: 2026-07-17
+---
+
+# Migrate to Supervision Without an OpenCV Dependency
+
+Supervision no longer installs OpenCV or offers an OpenCV extra. A standard installation includes the NumPy, Pillow, SciPy, and PyAV fallback needed by Supervision's image, drawing, and file-video APIs. When a compatible `cv2` is already installed, Supervision selects it once when the process imports the package.
+
+## Keep the default fallback
+
+Install Supervision normally when your application does not otherwise require OpenCV:
+
+```bash
+pip install supervision
+```
+
+The fallback keeps Supervision's documented APIs operational. Some text and anti-aliased drawing pixels can differ from OpenCV, so use the same backend while validating image-level baselines.
+
+## Prefer OpenCV behavior
+
+Install exactly one OpenCV wheel family when your application relies on OpenCV outside Supervision or needs its native behavior:
+
+```bash
+# Servers and containers without OpenCV GUI modules
+pip install opencv-python-headless supervision
+
+# Desktop applications that need OpenCV GUI modules
+pip install opencv-python supervision
+```
+
+Do not install both `opencv-python` and `opencv-python-headless`. If another dependency, such as a model runtime, already provides a compatible `cv2`, keep that installation instead of adding a second wheel family.
+
+## Verify the selected backend
+
+Backend selection happens at import time and lasts for the process lifetime. Run this command in a fresh Python process after changing dependencies:

+```bash
+python -c "from supervision import _cv2; print(_cv2.BACKEND_NAME)"
+```
+
+It prints `fallback` without OpenCV and the OpenCV backend name when `cv2` is available. `_cv2` is private; use this command only as an installation diagnostic, not as application API.
+
+## Capture webcams yourself
+
+Supervision's video helpers support file paths through either backend. Live camera capture remains application-owned, so install your chosen OpenCV wheel if you use `cv2.VideoCapture(0)`:
+
+```python
+import cv2
+import supervision as sv
+
+capture = cv2.VideoCapture(0)
+annotator = sv.BoxAnnotator()
+```
+
+## Roll back an upgrade
+
+If a downstream image baseline requires the pre-migration package behavior, pin Supervision below the first release that removes the OpenCV dependency, then plan a backend-specific migration separately:
+
+```bash
+pip install "supervision<0.30.0"
+```

+# Use Compact Masks for Memory-Efficient Segmentation
+
+[CompactMask][supervision.detection.compact_mask.CompactMask] stores each instance mask as a run-length encoding of its bounding-box **crop** rather than a full `(H, W)` boolean frame. For high-resolution images with many sparse masks this can reduce memory from tens of gigabytes to tens of megabytes, and eliminates full-frame decode work in annotators that only need the cropped region.
+
+!!! Note
+
+    `sv.mask_to_xyxy` keeps supervision's inclusive max-coordinate convention for compatibility with `CompactMask` and current box-based adapters. Use `sv.mask_to_roi` when you need exclusive slice bounds for NumPy indexing or crop extraction.
+
+This guide covers the four main integration points:
+
+1. [Ingesting COCO RLE payloads directly as CompactMask](#ingest-coco-rle-payloads)
+2. [Parsing Roboflow Inference results without a dense stack](#parse-inference-results)
+3. [Skipping mask materialisation for box/label annotators](#skip-unnecessary-materialisation)
+4. [Merging mixed dense and compact detections](#merge-mixed-detections)
+
+---
+
+## Ingest COCO RLE Payloads
+
+If your model or API returns masks in the COCO RLE format (`{"size": [H, W], "counts": "..."}`) you can convert them directly to `CompactMask` without allocating an `(N, H, W)` boolean array:
+
+```python
+import numpy as np
+import supervision as sv
+from supervision.detection.compact_mask import CompactMask
+
+# Example: two COCO RLE masks for a 720×1280 frame.
+# Replace the counts strings with actual compressed RLE payloads from your
+# model or API — e.g., from pycocotools mask.encode() or an Inference response.
+rles = [
+    {"size": [720, 1280], "counts": "YOUR_RLE_COUNTS_STRING_HERE"},
+    {"size": [720, 1280], "counts": "YOUR_RLE_COUNTS_STRING_HERE"},
+]
+xyxy = np.array(
+    [
+        [100.0, 50.0, 400.0, 300.0],
+        [500.0, 200.0, 900.0, 600.0],
+    ]
+)
+
+compact = CompactMask.from_coco_rle(rles, xyxy, image_shape=(720, 1280))
+
+detections = sv.Detections(
+    xyxy=xyxy,
+    mask=compact,
+    class_id=np.array([0, 1]),
+)
+```
+
+`from_coco_rle` uses run-length arithmetic scoped to each bounding box so no dense pixel array is ever created. Uncompressed integer count lists are also accepted in place of compressed strings.
+
+---
+
+## Parse Inference Results
+
+`Detections.from_inference` accepts a `compact_masks=True` flag that routes the Roboflow RLE payload through `CompactMask.from_coco_rle` instead of decoding to a dense stack:
+
+```python
+import supervision as sv
+
+# result: a Roboflow Inference v2 response dict with instance masks.
+detections = sv.Detections.from_inference(result, compact_masks=True)
+
+from supervision.detection.compact_mask import CompactMask
+
+assert isinstance(detections.mask, CompactMask)
+```
+
+!!! Warning
+
+    `compact_masks=True` crops each mask to its detector bounding box. Pixels outside the box are silently dropped. For masks that extend meaningfully beyond the reported bounding box, use the default `compact_masks=False` (dense decode) to preserve all pixels.
+
+To convert an existing dense-mask `Detections` to compact at any point:
+
+```python
+detections_compact = detections.to_compact_masks()
+```
+
+---
+
+## Skip Unnecessary Materialisation
+
+Annotators that do not draw masks (box, label, circle, ellipse, trace, keypoint) expose `requires_mask = False`. Integrations can branch on this flag to avoid decoding compact or RLE masks before annotation:
+
+```python
+import supervision as sv
+
+annotators = [
+    sv.BoxAnnotator(),
+    sv.LabelAnnotator(),
+    sv.MaskAnnotator(),  # requires_mask = True
+]
+
+for ann in annotators:
+    if ann.requires_mask:
+        # Annotator reads mask pixels — CompactMask decodes lazily per crop.
+        scene = ann.annotate(scene, detections)
+    else:
+        # Annotator ignores masks — strip mask field to eliminate any decode cost.
+        det_no_mask = sv.Detections(
+            xyxy=detections.xyxy,
+            confidence=detections.confidence,
+            class_id=detections.class_id,
+        )
+        scene = ann.annotate(scene, det_no_mask)
+```
+
+Annotators that set `requires_mask = True`: [MaskAnnotator][supervision.annotators.core.MaskAnnotator], [PolygonAnnotator][supervision.annotators.core.PolygonAnnotator], [HaloAnnotator][supervision.annotators.core.HaloAnnotator].
+
+All others default to `requires_mask = False`.
+
+!!! Note
+
+    `PolygonAnnotator` and `MaskAnnotator` both operate directly on `CompactMask` without materialising the full `(N, H, W)` frame — passing compact detections to them is already efficient.
+
+---
+
+## Merge Mixed Detections
+
+When merging `Detections` objects that mix dense `ndarray` masks and `CompactMask` instances, `Detections.merge` converts dense inputs to `CompactMask` automatically. No full `(N, H, W)` stack is allocated:
+
+```python
+import numpy as np
+import supervision as sv
+from supervision.detection.compact_mask import CompactMask
+
+H, W = 720, 1280
+
+# Compact detections from an RLE-based source.
+# Replace the counts string with a real compressed RLE payload from your model or API.
+rles = [{"size": [H, W], "counts": "YOUR_RLE_COUNTS_STRING_HERE"}]
+xyxy_a = np.array([[100.0, 50.0, 400.0, 300.0]])
+cm = CompactMask.from_coco_rle(rles, xyxy_a, image_shape=(H, W))
+det_a = sv.Detections(xyxy=xyxy_a, mask=cm, class_id=np.array([0]))
+
+# Dense detections from a different source.
+masks_b = np.zeros((1, H, W), dtype=bool)
+masks_b[0, 200:400, 500:800] = True
+xyxy_b = np.array([[500.0, 200.0, 799.0, 399.0]])
+det_b = sv.Detections(xyxy=xyxy_b, mask=masks_b, class_id=np.array([1]))
+
+# Output is CompactMask regardless of input order.
+merged = sv.Detections.merge([det_a, det_b])
+assert isinstance(merged.mask, CompactMask)
+assert len(merged) == 2
+```
+
+Merge rules:
+
+| Inputs                                | Output mask type                |
+| ------------------------------------- | ------------------------------- |
+| All `CompactMask`                     | `CompactMask`                   |
+| Mixed `CompactMask` + dense `ndarray` | `CompactMask`                   |
+| All dense `ndarray`                   | `ndarray` (backward compatible) |
+
+All `CompactMask` inputs must share the same `image_shape`; mismatches raise `ValueError`.
+
+---
+
+## Performance Notes
+
+These estimates apply to the **parsing and annotation stage**, not end-to-end pipeline FPS. Model inference typically dominates total runtime.
+
+| Optimisation                 | Realistic gain             | Applies when                                                  |
+| ---------------------------- | -------------------------- | ------------------------------------------------------------- |
+| `from_coco_rle` ingestion    | 25–60% faster parse        | Full-frame COCO RLE payload; current dense decode path        |
+| `MaskAnnotator` ROI blending | 10–35% faster annotation   | Many small, sparse masks on high-res frames                   |
+| `PolygonAnnotator` crop path | 15–45% faster polygon draw | Many compact masks; full-frame materialise was the bottleneck |
+| Mixed-mask merge             | 5–20% faster merge         | Mix of compact and dense sources (e.g. multi-camera stitch)   |
+
+Upper-end gains assume: ≥1080p frames, tens to hundreds of instances, masks covering less than ~20% of total pixels.

 This example benchmarks `CompactMask`, a new mask representation introduced in `supervision` that replaces dense `(N, H, W)` boolean arrays with a crop-scoped Run-Length Encoding (RLE). The benchmark demonstrates full API compatibility, massive memory savings, and order-of-magnitude annotation speedups — with no change to your existing `Detections` code.

 ## Benchmark
 
@@ -527,6 +527,69 @@ Run on any machine — no GPU or real model required:
 uv run python examples/compact_mask/benchmark.py
 ```
 
+For a focused benchmark of the Roboflow inference-result parser API, run:
+
+```bash
+uv run python examples/compact_mask/bench_inference_api.py
+```
+
+This script downloads all supervision image assets plus the middle frame from every supervision video asset by default, runs one real segmentation inference per source image, requests native RLE masks from Inference, freezes that result, and then compares parser performance:
+
+```python
+sv.Detections.from_inference(result)
+sv.Detections.from_inference(result, compact_masks=True)
+```
+
+Timing repetitions, warmups, confidence, IoU, response mask format, and the default model live as constants in `bench_inference_api.py`.
+
+Inference runs and segmentation-derived box fields are outside the timed benchmark loop. By default the script uses `rfdetr-seg-large` with `response_mask_format="rle"`; set `BENCH_INFERENCE_MODEL_ID` to override the model. Set `ROBOFLOW_API_KEY` when your model requires authentication. Sources where the model returns no native RLE segmentation masks are skipped because there is no RLE parser work to benchmark. `rfdetr-large` is a valid local Inference model id, but it is object detection only; use an `rfdetr-seg-*` model for instance segmentation.
+
+Run one specific supervision image or video asset with `--asset`:
+
+```bash
+uv run python examples/compact_mask/bench_inference_api.py --asset people-walking
+uv run python examples/compact_mask/bench_inference_api.py --asset soccer
+uv run python examples/compact_mask/bench_inference_api.py --asset vehicles
+uv run python examples/compact_mask/bench_inference_api.py --asset people-walking-video
+```
+
+The output reports image size, segmented objects, median parser time, peak traced allocations, mask storage, and parser speedup (`dense parser time / compact parser time`).
+
+**Speedup column:** The `speedup` value reflects allocation savings — how much time is saved by skipping the dense `(N, H, W)` bool-stack allocation — not a faster RLE decode. Compact RLE arithmetic is typically slower than the dense NumPy path. The net result:
+
+- **Compact is faster** only when the dense `(N, H, W)` bool-stack allocation dominates — large images with many sparse masks where avoiding that allocation outweighs the RLE arithmetic cost.
+- **Compact is slower** for small images or dense/overlapping masks, where Python RLE arithmetic dominates and the allocation cost is negligible.
+- **The primary guaranteed benefit is memory**: compact masks use roughly 99% less memory than dense stacks for typical segmentation output, regardless of which parse direction is faster.
+
+The default run includes a `synthetic-dense-64` row (64×64 image, 4 fully-filled masks) to demonstrate the adversarial regime where compact is slower than dense. For each real source with segmentation masks, the script also writes a validation overlay to `examples/compact_mask/outputs/*_segmentations.jpg`.

-# # supervision 0.28.0: Memory-Efficient Instance Segmentation
-#
-# [![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/roboflow/supervision/blob/develop/notebooks/release-demo_0-28.ipynb)
-#
-# **supervision** is a set of reusable tools for computer vision.
-# Two headlining changes in 0.28.0:
-#
-# 1. **`sv.Detections.from_sam3`** -- first-class support for SAM3 (Segment
-#    Anything Model 3) inference responses. supervision now parses both the
-#    PCS (prompt-controlled segmentation) and PVS (point-video segmentation)
-#    output formats directly into a `sv.Detections` object.
-#
-# 2. **`sv.CompactMask`** -- instance masks stored as RLE-encoded bounding-box
-#    crops instead of full-resolution bitmaps. Any segmentation model --
-#    RF-DETR Seg, SAM3, YOLO-Seg -- can feed into CompactMask. Memory drops
-#    10-100x without changing the API anywhere in supervision.
-#
-# **Story**: run RF-DETR Seg on a real image, visualise the masks, then convert
-# to CompactMask and watch the memory footprint collapse.
-#
-# **Sections:**
-# 1. [Install](#1-install)
-# 2. [Download sample image](#2-download-sample-image)
-# 3. [RF-DETR Seg -- instance segmentation](#3-rf-detr-seg)
-# 4. [CompactMask -- memory-efficient storage](#4-compactmask)
-# 5. [SAM3 -- text-prompted segmentation](#5-sam3)
-# 6. [Other notable changes in 0.28.0](#6-other-notable-changes)
-# 7. [Next steps](#7-next-steps)

-#
-# Key facts for this demo:
-#
-# - Pretrained on **COCO** (80 object categories) -- detects people, bags, cars, etc.
-# - Weights download automatically on first `RFDETRSegSmall()` call (~100 MB).
-# - `model.predict()` returns **`sv.Detections`** directly -- no converter needed.
-#   Masks are a `(N, H, W)` bool array attached as `detections.mask`.

-# ### `sv.ByteTrack` deprecated
-#
-# `sv.ByteTrack` still works in 0.28.0 and 0.29.0 but emits a
-# `DeprecationWarning`. Migrate to `ByteTrackTracker` from the external
-# [`trackers`](https://pypi.org/project/trackers/) package before 0.30.0.
-#
-# ```python
-# # Before
-# tracker = sv.ByteTrack()
-# detections = tracker.update_with_detections(detections)
-#
-# # After (pip install trackers)
-# from trackers import ByteTrackTracker
-# tracker = ByteTrackTracker()
-# detections = tracker.update(detections)

-# Release Process
-
-This doc outlines how supervision is released into production.
-
-It assumes you already have the code changes, as well as a draft of the release notes.
-
-1. Make sure you have all required changes were merged into `develop`.
-2. Create and merge a PR, merging `develop` into `main`, containing:
-    - A commit that updates the project version in `pyproject.toml`.
-    - All changes made during the release.
-3. Tag the commit with the new supervision version.
-    - make sure to pull from `main` !
-    - Verify that the latest merge commits exists. `git log`.
-    - Run `git tag x.y.z`, with your version
-    - Check with `git log`.
-    - Run `git push origin --tags`
-    - Upon pushing the Github release, the [PyPi](https://pypi.org/project/supervision/) should update to the new version. Check this!
-4. Open and merge a PR, merging `main` into `develop`.
-5. Update the docs by running the [Supervision Release Documentation Workflow 📚](https://github.com/roboflow/supervision/actions/workflows/publish-release-docs.yml) workflow from GitHub.
-    - Select the `main` branch from the dropdown.
-6. Create a release on GitHub.
-    - Go to releases
-    - Assign the release notes to the tag created in step 3.
-    - Publish the release.
