- Candidate carries only the fields the arbiter reads (key, label,
detected_strict, detected_relaxed, features); location/region/confidence were
vestigial from the removed best_auto_mark max-by-confidence path.
- resolve_backend returns preferred_inpaint_backend() directly (typed Literal)
instead of an identity ternary.
- colour/normalise/behaviour -> US spelling across code comments and docs.
No behavior change.

For AI-enhanced composites (digitalSourceType compositeWithTrainedAlgorithmicMedia,
identify ai_source_kind == "enhanced"; roadmap P1#8): regenerate ONLY the AI
region and preserve the real photo elsewhere, instead of regenerating the whole
frame.
- noai.tiling.feather_region_composite(base, regenerated, box, *, feather): pure,
model-free compositor that blends the regenerated AI box back over the original
with a feathered seam, leaving pixels OUTSIDE the box exactly equal to base.
Fully unit-tested (outside-box exactness, interior == regenerated, hard paste at
feather 0, monotonic seam ramp, dtype/grayscale/clamp/empty-box/shape-mismatch).
- WatermarkRemover.remove_watermark(region=, region_feather=) and the module-level
convenience function thread it through: the remover regenerates (or tiles) the
frame, then composites only the AI box back over the original input. The box is
caller-supplied -- a C2PA composite manifest carries no reliable machine-readable
region, so none is fabricated. The no-model lossless region path stays
region_eraser.erase.

Add a lossless alternative to the --max-resolution downscale for large
images that OOM on MPS/GPU: regenerate in overlapping, feather-blended
tiles at native resolution.
- noai/tiling.py: pure plan_tiles (uniform tiles, last flush to edge) +
feather_weights (strictly-positive separable taper -> partition-of-unity
blend) + run_tiled (per-tile generate callable, decoupled from the
pipeline). Unit-tested without the model.
- WatermarkRemover.remove_watermark: refactor _generate into _generate_one
+ a tiled branch that engages only when --tile is set and the long side
exceeds tile_size (ControlNet canny is rebuilt per tile).
- Thread tile/tile_size/tile_overlap through InvisibleEngine and the
invisible/all/batch CLI commands via a shared _tile_options decorator.
Verified end-to-end on the real SDXL pipeline (forced 2x2 tiling on a
1024px sample, MPS): non-degenerate output, no gross seam at tile borders.
