+**FR-DEV-3i — Model-found masks.** A mask layer's part may be a thing a model found in the
+photograph, selected by pointing at it: one **subject** — this dog, not that one — from an
+instance model, or one **category** — all the sky, all the foliage — from a semantic model. The
+selection is stored as *identity* (which run, which instance or which category name, with the
+run's signature) so that two devices selecting the same subject hold the same value and merge per
+field under FR-NC-9, and a layer whose run no longer matches reads as **stale** rather than
+silently masking something else. The mask arrives approximately right and soft, and it is then an
+ordinary layer: FR-DEV-3's edge treatment shapes it, FR-DEV-19b's strokes correct it, FR-DEV-19a
+composes it with a gradient or a range, and FR-DEV-19c shows it. Inference is local

+*Added 2026-09-19, because it was built and §7 still said it was deferred.* The deferral treated
+subject masking as an AI feature to be copied from Adobe or darktable; what was built is the
+shape §7's own note asked for — a mask that behaves like a hand-drawn one — and it has been the
+primary way a local adjustment is made since the watershed hierarchy failed on real photographs
+(`docs/segmentation.md` §15).
+
+One departure from FR-DEV-19 is recorded rather than hidden. A model-found part's coverage is
+also written to the sidecar, run-length coded beside the layer, because a stored subject that is
+"reproducible by running the model again" renders as nothing on a device or in a batch export
+that never runs a model. It is a materialisation of the identity, not the edit: it takes no part
+in equality or merge, and the identity remains what the part means.

Note darktable shipped this in 5.6 (June 2026), so the gap is now visible. **Conditions for deferring safely:** AI denoise ships in v1 (FR-DEV-3g ✓), manual masking is excellent including GPU-rasterised drawn masks (ARCH §6.11 ✓), and the product has a clear differentiator (culling, §3.9 ✓). When it does land, copy darktable's shape — prompt-point segmentation producing an *editable* mask that behaves like a hand-drawn one — not Adobe's opaque version. |
