Change

Deliver the reviewed canonical spacing and safer Return changes from microsoft/amplifier-client-web#63 (merged as 616d5a1f2026f4f864bf185f8533433bcee47ec2, tree-identical to the selected reviewed ad9d5dfedddf12ea6e99910717280cc37a56da76). Whole 676-file snapshot, bytes/modes and source digest refreshed mechanically; no copied-source authoring. Source digest: 1c54edf8f8016ea7ba07d8f2bf90c1069ed07be5ef335fbf5dfbceaa3aa3b276.

• Checkbox/search/select spacing, dense Settings and Work status/retry separation; error banner follows the chat/composer column.
• Browser-local Return preference and capability default preserve IME, rich editing, explicit guarded Send and draft recovery. Visible effective guidance stays outside the compact writing border; 44px controls and the existing 72px compact ceiling remain.
• Maintained outside-checkout installed journeys and synthetic fixture controls; strengthened measured geometry and storage acknowledgement oracles.
• Add bounded external-static capture to the maintained frontend artifact helper. It verifies selected client, prepared source, shared inputs, paired-lock metadata and all generated bytes before/after capture; ordinary verify/apply remain unchanged. This does not grant build/release qualification.

Validation

One owned managed browser-test DTU only, matching prepared dependencies reused. Final actual tested host source 9398201912ee23be1857299e31397362f9b5daec (0.96.4 base); selected client ad9d5dfe, build 705284ec2b3ff778. Candidate wheel SHA-256 252a88c5d4fa12ee78ad8435ec9cab39a6527af8e44e3b46b8a71b117cedf99a; all 952 amplifier_web payload members verified after installation outside source/PYTHONPATH. Served app JS 38bd5508b47042912624cde094aa51bef6398b26fa17dd2f5fc12c4a404807a6, CSS 90bd6929302db8434ba2aaeab29cd433c96f82b93a932e7ab8696c805db4cc16.

PASS:

• Canonical Return capability/event matrix, mounted failed-storage/disabled/readOnly and nine native/deferred rich-edit + undo/redo cases; shared controls accepted on unchanged production input.
• Installed compact, Return and Markdown journeys. 24 compact detail/scheme/width cases at 900/520/390/320: field 56/60px, controls/editor 44px and centered; visible associated guidance outside border, no overflow. 160px negative control and two help-inside cause controls rejected.
• Installed banner (1440/768/420/390), expanded Voice/Appearance/Routing/Testing/document-action scenes, and loading/error/retry geometry with real fixture host publication. Unchanged relevant CSS proof reused from exact earlier 8e4/2f97 builds, with full original wheel/served-byte joins and independent bounded screenshot review.
• Frontend artifact helper: 53 passed in the same prepared DTU; full 316-file transferred static tree captured, verified, applied and web_client_build.py verify passed.

Retained finite raw results, hashes, screenshots, failed attempts and source snapshots: task d5715468 / working-files/layout-delivery/ and final delivery-final.json in the task-owned workspace output. Parent dca3 owns the independent source and pixel review receipts.

Current Main 89908c631 was merged without conflicts after the tested source. Its execution-preparation witness optimization, scheduling changes and accepted kernels delivery are preserved. UI/client/lock inputs are unchanged by that union; local final selected-client/static verification passed. The exact final union was not rebuilt or re-exercised in a new DTU, and the 939 wheel is not represented as that union. Artifact pairedServer remains the pinned shared-input identity 816c7a67…, not the actual 939 tested host.

Limits: synthetic host/runtime, no paid provider or copied user data/credentials. No physical mobile/native IME or actual 200% browser zoom acceptance (reflow viewport evidence is labelled). Earlier failures remain failures, not aggregate green. No release/version change, live adoption or Companion work.

Cleanup: sole DTU and owned image removed through managed receipts after finite evidence retention; inventory marked reaped. Original source and historical-contract archives retained. Independent absence observation is separate from our confirmed teardown.

Release coordination — RM owns the single next normal app cut for this layout handoff. Latest published app is v0.96.5; proposed patch is 0.96.6, with an explicit notice that Automatic Return inserts newlines on touch-capable browsers and explicit Send remains available. No build, tag, merge or publisher has been started for this cut. Required Fast/client-performance failures on f6c381 are being repaired by the existing layout owner; they will not be bypassed. Accepted rendered/package evidence is reused only at unchanged inputs. Remaining release preparation/output review and the one normal automatic publisher/official installed-package smoke stay in the RM lane. Context-limit incident recovery, its upstream approval question and Mac access are separate and are not claimed fixed by this UI change. No live adoption or repeat of 0.96.4/0.96.5 is commissioned. Any existing competing reservation must be reconciled before preparation, not raced.
