Record what the spec got wrong about the model that exists

docs/segmentation.md §4 priced arm B as costing a C dependency under the NDK and treated that as most of the difference between the arms. It is not a cost that has to be paid: `ort`'s `alternative-backend` disables its linking entirely and `ort-tract` supplies the API from tract, which is pure Rust. D13's "largest exception the policy would tolerate" turns out not to be needed, and the answer generalises to the face pipeline — so D13's runtime half is now answered and only its licensing half is open. Three findings contradict §4 outright and are recorded as F4-F6 rather than quietly designed around. There is no ADE20K-trained YOLO, so the shipped vocabulary selects subjects and not stuff — "select the sky" comes from the watershed or from nowhere. It is instance segmentation, so it partitions nothing and two people come back as two instances. And tract cannot parse a dynamic-shape export, which fixes the input at 640 square and makes tiling the only route to more semantic resolution. Arm C ships, but §8's criteria are not what decided it, and saying so matters more than claiming the process worked. §8 asked for a two- interaction margin over arm A on a traced corpus. That comparison was never run: F4 and F5 changed what the arms are, and a model that recognises subjects but has no word for sky cannot be a selection tool alone, while a watershed cannot tell a person from the wall behind them. They stopped being candidates and became complements. What is *not* done is written down as plainly: the 24-image corpus is untraced, so M1-M4 have no numbers and "this feels right" has not become one. M5 is answered on one device only, and region ids now reach the sidecar — so a cross-vendor divergence would mean a mask written on the desktop meaning something else on Android. F3 stands.

 §3.9.1 needs to run two neural networks locally. That collides with two settled positions, and
 neither collision is small enough to leave implicit.

 reference desktop's CPU. Correct masks on the standard `bus.jpg` — one bus and three people, outlines
 following the subjects.
 Three findings that contradict §4 directly, and all three change the design rather than the schedule.
 **F4 — there is no ADE20K-trained YOLO.** §4's whole argument for arm B was ADE20K's 150 classes and
 their *stuff* categories: "'that patch of sky' is a class here." Checked 2026-08-21: Ultralytics ships
 YOLO26-seg trained on **COCO**, whose 80 classes are all *things*, and the one HuggingFace repository
 claiming a YOLO/ADE20K combination is empty. ADE20K models exist as SegFormer/OneFormer/MaskFormer
 transformers, not as YOLO.
 So the shipped vocabulary selects **subjects**, not **stuff**. "Select the person" works; "select the
 sky" does not come from the model at all and must come from the watershed. That is a narrower arm B
 than §4 assumed, and it *raises* the importance of arm C rather than lowering it — the model can no
 longer be the whole answer for anything.
 **F5 — it is instance segmentation, not semantic segmentation.** §4 assumed a flat partition with
 class ids that would "populate `RegionField` directly". YOLO-seg does not partition the image; it
 finds objects, and most pixels in a landscape belong to no instance. Two consequences, one bad and
 one better than expected: nothing populates a `RegionField` on its own, and two people come back as
 *two* instances where a semantic model would have returned one "person" area covering both. For
 selecting a subject the latter is the behaviour worth having.
 **F6 — tract cannot parse a dynamic-shape export.** It fails shape inference on the neck's `Concat`.
 The graph therefore ships with its input fixed at 640×640 square, and every image is letterboxed into
 it. This is the constraint behind the tiling option in `semantic.rs`: with a fixed window, tiling is
 the *only* route to more semantic resolution, and it costs one inference per tile (≈2.8 s for a 3×2
 grid over a 1600 px proxy against 470 ms whole-frame). Defaulted off — a photographic subject is
 usually large in frame, which is the case whole-frame inference handles best — and left implemented
 so §9's corpus can settle it rather than an argument.
 **Arm C ships, and the §8 criteria were not what decided it.** §8 asked for a two-interaction margin
 over arm A on the scene subset. That comparison was never run, because F4 and F5 changed what the
 arms *are*: with a model that recognises subjects and has no word for sky, arm B alone cannot be a
 selection tool at all (§8's "arm B never ships alone" holds, for a stronger reason than expected),
 and arm A alone cannot tell a person from the wall behind them. They are complements rather than
 candidates. Arm C's implementation is `prior.rs`: instance membership re-weights the merge saddles,
 so region pairs the model believes share an object merge early and pairs straddling its edge merge
 late. **No boundary moves** — only the order in which boundaries dissolve — which is how the result
 stays pixel-accurate at every level while its coarse levels become named things.
 **M1–M4 remain unmeasured.** The 24-image corpus of §9 has not been traced, so there are no
 interaction counts and no boundary-accuracy numbers. What exists is a working feature and the
 evidence that each piece does what it claims in isolation. The corpus is still the thing that would
 turn "this feels right" into a number, and it is the largest piece of §11 left undone.
 **M5 is unchanged and still the risk it was.** Run-to-run on one device is identical, asserted by a
 test. Cross-vendor is untouched. Region ids now reach the sidecar, so if the label field proves
 non-deterministic across vendors a mask written on the desktop will not mean the same thing on
 Android — see `MaskSource::Regions::signature`, which detects a *retuned* segmentation but not a
 differently-rounded one.
 **F3 still stands.** `Segmentation::read_field` still copies the label and gradient buffers to the
 CPU to build the region graph. It is now behind its own `segment-readback` feature rather than
 sharing `readback` — this transfer is once per image on a worker, where the one AC-8 forbids is per
 frame in the render loop — but the accumulation still belongs GPU-side with atomics.

 ## 14. Register entries
 **S15** — *Region segmentation for local masking* · **CLOSED 2026-08-21**. Arms A, B and C built; the
 shared consumers built; the licence question resolved (§7, D14). The 24-image corpus was not traced,
 so M1–M4 are unmeasured and M5 is answered only on one device. Answers: local masking snaps to arm C,
 and a mask is stored as region ids. Relates to: D13, D14, FR-DEV-3, ARCH §5.4, §6.13.
 **D14** — *Segmentation source for local masking* · **DECIDED 2026-08-21**: **arm C**, a watershed
 hierarchy re-weighted by YOLO26n-seg instance membership, with the model optional and the watershed
 sufficient without it. Weights ship in-tree under AGPL-3.0, which GPLv3 §13 permits and which makes
 the combined work effectively AGPL — a deliberate change to DarkRoom's licensing posture, not a
 dependency detail (`core/dr-segment/models/LICENCE.md`).
 **D13** — *inference runtime* · the dependency half is **answered** for segmentation and the answer
 generalises: `ort` + `ort-tract` gives ONNX inference in pure Rust, so the face pipeline of §3.9.1
 needs no C dependency either. The *model licensing* half of D13 is untouched — the InsightFace
 weights are still non-commercial and still unusable here.
