+fires the moment the scan completes, which is the first moment the rows the merges key on exist,

+takes **capture metadata** (`captured_at`, offset, camera, lens, ISO) for images still at

+state, and the snapshot already carried it; the sweep's per-chunk query then finds nothing left.

 **The transfer**, in `dr-ui`'s `derived_sync`, exchanges shards with `.darkroom-derived/` under the
 library root. `ThumbStore::shards()` reports which are sealed, so an up-to-date client's whole pass
 is one listing plus whichever shard is still open.

+### 3.12 Inference runtime
+
+The face, segmentation and border-fill models run under an inference engine the application
+selects per device. [inference.md](inference.md) is the design: its §3 sets the dependency policy
+the runtime may reopen, its §10 the milestones (M1–M7) the clauses below cite as acceptance. The
+clauses are the register entries inference.md §12 promised; they are stated here so the
+traceability gate can count them.
+
+**FR-INF-1 — Runtime selection.** On launch the application shall determine, per device and
+without blocking the first frame, the fastest inference backend that can build and run a session
+for the shipped models, by attempting it; shall record and reuse that determination until the
+runtime, driver, hardware or models change; and shall display the backend in use in Settings and
+on the about screen. *Acceptance:* inference.md §10 M1 and M5.
+
+**FR-INF-2 — Derived engines.** Backends that require device-specific compilation shall compile in
+the background after selection, shall serve requests from the next lower backend until each engine
+is ready, and shall not change the backend of a job in progress. *Acceptance:* M5.
+
+**FR-INF-3 — Model forms.** Quantised model forms are produced at release time from real
+calibration data and are shipped only when they meet inference.md §10's accuracy gates against the
+canonical form; the application never quantises on the device. *Acceptance:* M2, M7.
