Full-width header correction
Base 0a2cdddcd794c10b254e28e83674e76cb3f50f53. Release source 7416ffe5382cb420fb2e727955eb04a812a6beb2. This extends spec057 after the user supplied a wide-window screenshot.
Only blank drag space expands. Workspace mark/name/context form one compact group immediately after navigation and New Tab. Native HeaderBar, CSD, breakpoints, Details metadata, attention and terminal identity remain covered.
Evidence
- Baseline red: staged native regression on the baseline production layout, actual 1270px window, title 197px allocation for 58px ink.
- Final dedicated native run: same assertions at 1270px and 2390px LTR/RTL, title 58px allocation/58px ink. Narrow long title 120px at Sans11/Sans18; active attention retains 67px. Keyboard order, Details, drag-space minima and VTE identity pass.
- Shared-display focused run: up to 1510px on the 1600px monitor. The test bounds requested wide width by monitor width minus 80px, capped at 2400px. No case is skipped.
- Toolbar interactions: exact existing test passed.
- Full gate: clean source 7416ffe, 55 steps passed, 43 isolated GTK tests plus server QA and refresh benchmark.
- Independent reviews: Spec and Standards axes, with visual evidence objection resolved before publication.

Native renders
Same 890px fixture, Changes closed in both captures:
| Before | After | Why |
|---|---|---|
| Identity sits away from navigation | Identity starts immediately after navigation | Keeps workspace context in one reading group |

Wide renders below are standalone 2390px acceptance evidence. The transient 1280px light capture is excluded: it contained a strip of Changes during closing. Its mismatched panel state is not used as a comparison.

An earlier full run on 1e2b5c2 was interrupted after discovering the shared monitor clamps 2400px requests. The completed full-summary above supersedes it. Focused logs include portal fallback and GTK measurement/snapshot warnings during resizing; visual acceptance uses stable final states.
Actual compositor fullscreen/maximize/dragging, screen-reader speech, OSK and IME were not run. Xvfb geometry does not certify them. Remaining raw full logs are under /tmp/full-width-header-full-final-20261014; the committed summary records every command/result and tool versions.
