Unify dock surfaces, headers and dividers, and remove the visible context strip.
Limit pointer resizing to 400-640px and reveal the edge grip on hover.
Resize and redraw the map in the same layout cycle to prevent blanking and lag.
Preserve horizontal centering during conversation control press feedback.
Validation: isolated lint, typecheck, 21 focused unit tests, and 10 relevant
browser checks passed. Snapshot baselines regenerated from the isolated change.
The existing mobile alert summary test also fails on unchanged HEAD because
the expected demo alert source is unavailable in this environment.
The not_configured branch previously promoted mock task failures into critical alerts. Return an explicit empty alert source so the exception badge reflects only actionable backend state.
Optional sources became dynamic while dependent labels and controller state remained static, allowing stale requests to restore removed layers. Register dependent layers through the same lifecycle and invalidate target request generations before release.
Independent fixed offsets caused the timeline, map dock, tool panel, and zoom controls to overlap. Derive them from one layout function and scope collapse to the expanded timeline state.
The regression recurred because a floating timeline height was still exported as shared layout space and its z-index exceeded artifacts and notices. Reserve zero layout height and define the timeline below artifact and notification overlays.
Keep ScaleInfo pinned to the map corner and move the centered timeline above collisions, preventing the previous conditional offset from lifting the scale. Remove collapsed Agent rail width reservation and add timeline state transitions.
The regression came from applying history-open styling to the outer acrylic shell during iteration. Keep the shell frame unchanged, confine the bottom edge treatment to the expanded header, and cover desktop and mobile geometry in Playwright.
Unify the Agent history extension with the header acrylic surface, preserve the full conversation body, and consolidate shared control and status styling.
Restore map flow and SCADA controller behavior, remove obsolete rendering paths, and extend regression coverage. Button press coverage now releases outside the target so state assertions cannot accidentally toggle the control.
