Record where a linear DNG too large for one texture goes

ARCH §5.3 still described only a tile cache nobody built; it now says what 0.19.0 tiles and what it does not: a linear DNG past PROXY_EDGE opens on a reduced copy, a finer render samples a full-resolution window, and the export is cut into halo-grown tiles. display-and- extension.md's FR-DSP-2 row said absent, outstanding.md said the halo had nothing to read it and that such a file fell to the embedded preview. rawler now builds from third_party, which ARCH's stack table and §3.2, the root Cargo.toml's comment ("two upstream crates ... for Android") and third_party/README.md's bump procedure did not know; the README also names each vendored crate's licence. panorama.md and the manual say a composite this wide develops and exports.

 | Requirement | Reality |
 |---|---|
 | FR-DSP-1 proxy rendering | **Done.** The develop view renders at viewport resolution, not source. |
-| FR-DSP-2 tiled computation | **Absent, and §2 now says it should stay that way.** Measured: the fused pass is inside the budget everywhere. See [frame-budget.md](frame-budget.md). |
+| FR-DSP-2 tiled computation | **Absent from the interactive path, and §2 now says it should stay that way.** Measured: the fused pass is inside the budget everywhere. See [frame-budget.md](frame-budget.md). *Since 0.19.0* the export of a linear DNG too large for one texture is drawn in halo-grown tiles, and the canvas renders such a file from a reduced copy and full-resolution windows (ARCH §5.3). |
 | FR-DSP-3 interactive latency | **Measured and asserted** for the fused path — `core/dr-gpu/tests/frame_budget.rs`. Missed by one operation, clarity, for the reason recorded as TD-4. |
 | FR-DSP-4 progressive refinement | **Built** (0.15.0), although §4's condition did not fire on the fused path: a half-resolution draft while a gesture moves, one sharp frame 120 ms after it stops, the histogram dimmed while it lags, and the draft faded out over 150 ms — `ui/dr-ui/src/refine.rs`. See [frame-budget.md](frame-budget.md). |
 | FR-DSP-5 zoom and pan | **Done and tagged**, against tests that fail if the behaviour is removed — `core/dr-gpu/tests/zoom_resolution.rs`. `Framing::view` shrinks the sampled region while the render target keeps its size, so zooming *raises* the resolution the pipeline works at. That is FR-DSP-5's requirement, arrived at without tiles. |
