Why: Upload inventory alone did not prove that the attachment-only user message included and persisted all three materials.
Evidence: Real upload IDs match the empty-text POST and the same user artifact_ref parts before and after reload; both live cases pass.
Impact: Stronger acceptance evidence only; retain mock-runner model-quality limits.
Refs: ce-code-review 20261012-165912-cb241b46 #4, UI01/UI04/U5
Why: Ordinary explanations were folded with tool activity and the oldest result was selected as current work.
Evidence: Findings #5/#6 red-to-green actual-component and live-projection checks are retained; current full Frontend suite passes 210 cases.
Impact: Preserve business text, errors and file references in reading order; retain active/pinned priorities and newest-first host ordering.
Refs: ce-code-review 20261012-165912-cb241b46 #5/#6, UI03/UI05
Why: Background frames blocked terminal reconciliation, stale failures left confirmations busy, and delayed page hydration changed mobile navigation.
Evidence: Review findings #1/#2/#3 have recorded red-to-green checks; all 210 Frontend tests, tsc and knip pass, plus six real navigation browser checks.
Impact: Keep sequence high-water and operation ownership, merge observations by object, and use an explicit preview-opening intent.
Refs: ce-code-review 20261012-165912-cb241b46 #1/#2/#3, UI04/UI09/UI10/UI11
Why: Retained React nodes alone did not prove actual browser scrolling was preserved.
Evidence: The settled Chromium case failed on the previous bundle, then all 11 browser cases passed with exact material, scroll and focus assertions.
Impact: Browser regression coverage only; fixture transport stays outside the production bundle.
Refs: UI10, ce-code-review UI finding #3, work-companion-ui
Why: Opening the auxiliary work pane should keep the conversation compact.
Evidence: Existing Playwright browser suite passed all 10 cases, including finished Collapsible transition.
Impact: Test and screenshot timing only; product behavior is unchanged.
Refs: Dev feature/work-companion-ui, UI03
Why: make material, background work, confirmations and files accessible to nontechnical users across desktop and mobile.
Evidence: Dev SELF receipts for Frontend tsc, 190 tests, knip baseline, build, nine fixture browser cases and two real HTTP/browser smoke cases using MockRunner.
Impact: existing API and permissions remain authoritative; stale events/queries and duplicate effects are guarded, while one file preview and reading state are preserved.
Refs: work-companion-ui design r0.2 and plan r1 U2-U5; UI01-UI13.
