 ## Where things stand
 
-Canonical `main` is **`32b1038`** (#14, SetSize). Twelve slices are in. One
-pull request is open and one branch is pushed but unopened:
-
-- **#12** `split/12-pointer-routing`, worktree `/home/bob/repos/iris-pr12`,
-  head `e53ce58`. Reworked twice after review: a layer, not a widget, is what
-  consumes input. `CursorSenses::consumes` decides only whether a layer stops
-  the input reaching the one below, and senses on one layer never block each
-  other. The vocabulary is `position_only`, not "momentary". Five tests; two
-  fail on `main`. **One question is out to her**: whether to replace
-  `registered` with a `consumed: &Cell<bool>` on `CursorData` that
-  `should_run` sets, which also removes the double match.
-- **#15** `split/15-harness`, worktree `/home/bob/repos/iris-pr15`. `Tasks`
-  takes an `Arc<dyn WakeTaskQueue>` instead of an `Arc<Window>`, so
-  `DefaultRsc` builds without one, and `iris::harness` drives a ui with no
-  surface. Six tests in `tests/harness.rs`. Disjoint from #12.
+Canonical `main` is **`43ce8c7`** (#12, pointer routing). Fourteen slices are
+in and nothing is open.

 ## The next slice
 
-**The headless rig.** `scripts/run-headless.sh`, `headless.conf` and
-`rig-input` are still only in ai-app's iris submodule, so every rendering
-claim in canonical Iris is verified by hand from another checkout. The harness

+**Widget draw size and measurement** (source commit `6671194`), because it
+reaches furthest: `desired_width`/`desired_height` and `SizeCtx` go, a widget
+sizes itself during `draw` with `painter.set_size`, and `size_hint` is the
+cheap answer for a parent that needs a size without drawing. Every widget's
+body changes, so anything written before it is written twice. It also deletes
+the separate measurement recursion and its cache.
+
+It is testable now that `iris::harness` is in: `tests/layout.rs` is where the
+acceptance goes.
+
+Two things to settle with the owner before writing it. The archive's `Widget`
+grows five methods — `size_hint`, `is_size_independent`, `requires_exact_region`,
+`access_role` and `child_order`; only the first three are sizing, and she
+dislikes capability methods on the core trait, so `requires_exact_region` in
+particular wants justifying (`Pad` sets it and then clears it when the content
+fits, which reads as a workaround). And the archive writes all of it against
+`LayoutLen` and `density`, which canonical does not have — recreate it on
+today's `Len` and let the dp slice follow, rather than pulling both in at once.
 
 Still in the target, roughly in dependency order:
 
+- **`Len`, `LayoutLen` and dp.** The archive splits the type so that `rest` is
+  unrepresentable where it is meaningless (a padding), and folds a density in
+  at resolve time. 21 files mention `Len`, so it is wide but shallow. After the
+  draw-size slice, not before: that one deletes the `desired_*` bodies this
+  would otherwise have to be threaded through.
 - **The input restructure** — `src/default/sense.rs` becomes `src/rsc/sense.rs`
   (308 lines to 2313), plus `core/src/event/controller.rs`, `desktop/input.rs`,
   `android/input.rs` and `sense_tests.rs`: pointer capture, drag slop and axis,
-  platform cancellation, mask-aware hit testing, event timestamps. It replaces
-  the file #12 fixes. The archive's own `consumes` is what #12 now implements,
-  so that part transplants; `tests/pointer_routing.rs` is the acceptance
-  criterion for the slice.
