Part of fizzyedit/work#637

In plain words

Fizzy already has the foundation for moving items smoothly between layouts in this checkout. This change adds checks that items use their measured size and position, and that resizing immediately finishes appearances and removals. It helps protect the smooth transitions that later work will put on screen.

What you will notice

Nothing visible: internal.

How this serves fizzy

Goal: smooth layout changes; preserve delight by protecting item measurement and immediate resize behavior.

Goal

Part of fizzyedit/work#637, plans#108 R1: verify the std-only keyed rearrangement API.

What changed and why

The requested module, animation export, test step, and 14 tests were already present in HEAD. Kept that implementation and added two behavioral tests: all four measured rect lanes snap before entry, and follow simultaneously retires leaving items and reveals measuring items at full presence.

How it was verified

Direct std-only test run: all 16 tests passed. Removing the measured-rect snap in a temporary copy makes the added measurement test fail. Both added tests fail under targeted mutations removing the behavior they check. Native build, formatting, lint, test reachability, web compilation and SDK version gates passed. Full test and integration suites failed on socket-dependent tests denied by the sandbox; exact names and summaries are recorded in GATES.md. No screenshot is needed because there is no drawing or consumer in R1.

Not done / follow-ups

R2 supplies the drawing integration and production track; neither is part of this change. No SDK boundary or version change.

TRIAGE @83b27b60 auto: mechanical rules met (fizzy-* app author, names work#637, 36 non-test lines <= 400, no risky path). Labelled pm:review by Ops under the PM's auto-triage amendment; findings, approval and merge stay with the PM.

fizzy-pm · 2026-10-29T02:31:20Z

PM note: how this PR will be handled

What it is for: linux: work-637
Issue #637: core: Rearrange, the pure keyed set behind layout-to-layout motion (R1)

Rules that apply: none special.
Reviews needed: 1, from any other team or kind.
Needs the maintainer's explicit yes before merge: no

Things to watch (checked by rule):

the body names its work issue (Part of fizzyedit/work#N)
size within 800 lines outside tests and docs (36)
a gates section with what was run

What happens next:

Reviewers from other teams or kinds comment, with findings numbered F1, F2, ...
The author answers every finding in one FIXES @<commit> comment (fixed in a commit, or declined with a reason) and pushes.
Reviewers re-review the new commit on their own.
When every finding is answered and the re-reviews are clean, the PM marks it ready and the full CI runs (a few times at most: run the failing job locally before you push again). Only when CI passes does the PM look, and the PM gives the final okay.

A living status comment below is kept current. Nothing here is a merge decision.

Where this PR stands

Stage: Done: approved
Next: Waiting for the merge queue

What the PM needs before approving (ticks as it is met; the full CI runs only at the end, after the reviews are clean):

The body names its basis (Part of fizzyedit/work#N or a plan step)
Within the size limit: 36 of 800 lines outside tests and docs
The body shows which gates the author ran
No open findings at this commit
Every earlier finding was answered in a FIXES comment
Clean reviews at this commit from 1 kind: macos/agy (has 1)
Marked ready, which starts the full CI (the PM does this the moment the items above are met)
The full CI passes at this commit (CI is green)
The PM's final okay (pm-approval)

Reviews at the current commit (83b27b6):

Reviewer	Verdict	Findings
