…anation sheet says when it changes The explanation behind the (i) button did not open on the first hover of a fresh window, and did after hovering a tab word first. Measured with a copy of the window whose driver logged every refresh: canvas.Refresh(r.button) asked for the Button embedded inside DetailButton, while the tree and the driver's object-to-canvas cache hold the DetailButton - a different interface value, so no canvas was found, nothing was marked dirty and the box put on the sheet was never painted until something else repainted for its own reason. The test driver cannot see this: it answers CanvasForObject for any object and its canvas ignores Refresh. - parts: redraw(pieces...) - every renderer names the pieces it draws, seven renderers unified, no canvas.Refresh left in parts or window - parts: Tips.open and close refresh the sheet, which also fixes the keyboard path - Space on the focused button added a box nothing painted and removed one that stayed drawn - guard: canvastold_test.go reads both rules from the source, since nothing behavioural can; detailpopup_test.go hovers through the canvas on the visible screen and refuses a button drawn nowhere - screens: generate-hovered and generate-refused-setting regenerated - both had captured a stale icon raster, the painter behind the stored pictures keeping an image until the image itself is refreshed Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

In `@internal/guard/canvastold_test.go`:
- Around line 284-285: The rendererRefreshOffences validation currently counts
redraw arguments without verifying coverage of modified renderer pieces. Track
fields passed to Refresh, Show, and Hide, then require every modified field to
be included in the redraw call; alternatively compare applicable non-widget
Objects results against redraw arguments.
- Around line 368-373: Update the box event-tracking logic around boxesTouched
so it records the source position of the latest Add, Remove, or RemoveAll
mutation and the latest Refresh for each box. When evaluating the guard, require
the Refresh position to occur after the final mutation; report an offence when
it is absent or precedes that mutation, while preserving existing behavior for
boxes without mutations.

…d after its last change Two things an outside review of the pull request pointed at, both about the guard and neither about the window. The renderer rule counted the arguments of redraw and asked nothing of them, so a face setting four pieces and naming three passed. It now reads every field set on a piece and every piece shown, through the renderer's own methods, and requires each to be named - Show on a canvas primitive or a container sets Hidden and stops in the pinned toolkit, where Hide, Move and Resize repaint by themselves. Measured on the seven renderers: 21 pieces changed, all named, and dropping any one of them turns it red. The box rule accepted a refresh anywhere in the method, so a refresh standing before the change counted. It now takes the last change and the last refresh and requires that order. What it still cannot see is written at the top of the file. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Require redraw after the final piece change.
rendererReading records only whether a piece was changed and whether it appeared in any redraw call. Therefore, redraw(r.bg) followed by r.bg.FillColor = next passes the guard even though the final mutation has no later refresh. The visited map also skips a later invocation of the same helper, so a repeated helper call can mutate a piece after its recorded redraw without being checked.
Track ordered change and redraw events, and use recursion-stack cycle detection instead of once-only helper visitation. Require each piece's final redraw to occur after its final change.

What
The explanation behind the (i) button did not open on the first hover of a fresh window, and did after hovering a tab word first. Reported from the released build.
Why it happened
Measured with a copy of the window whose driver logged every refresh, hit test and paint: the pointer reached the button,
MouseInran, the explanation was placed on its sheet at the right position - and no repaint followed.canvas.Refresh(r.button)in the button renderer asked for theButtonembedded insideDetailButton, while the tree and the driver's object-to-canvas cache hold theDetailButton. A different interface value is a different cache key, so no canvas was found, nothing was marked dirty, and the box waited for a repaint caused by something else. Hovering a tab word first supplied one in the same tick, which is the whole of the "works after the tab word" pattern.The test driver cannot see this: it answers
CanvasForObjectfor any object and its canvas ignoresRefresh, so every guard that hovers, taps or reads the tree stayed green.What changed
parts/redraw.go: a renderer names the pieces it draws (redraw(r.bg, r.ring, ...)) and never the widget. Seven renderers unified, nocanvas.Refreshleft inpartsorwindow.parts/detail.go:Tips.openandcloserefresh the sheet. This also fixes the keyboard path - Space on the focused button added a box nothing painted, and removed one that stayed drawn - because a key press changes no face.guard/canvastold_test.go: two rules read from the source, since nothing behavioural can see them - renderers redraw pieces and never a widget of the package, and a container field that gains or loses a piece is refreshed in the same function (the convention every box inwindowalready kept).guard/detailpopup_test.go: hovers through the canvas on the visible screen and refuses a button drawn nowhere, instead of callingMouseIn.Verified
PAINT1 ms afterIN. Keyboard: Shift+Tab, Space opens, Space closes, the sheet asking for both repaints.🤖 Generated with Claude Code
