Every pixel oracle tried for STA-2694 was blind: `drawImage` on a non-preserveDrawingBuffer WebGL canvas returns a re-rendered copy, and Playwright's screenshot drives a fresh compositor frame that heals a stale paint before capture. Reading pixels is self-defeating here — the read triggers the repaint that hides the bug. Count the WebGL draw commands instead, by wrapping GlyphRenderer.updateCell and gl.drawElementsInstanced on the live pane. A draw command cannot be healed after the fact, so "did the reveal actually repaint?" becomes directly observable. Teeth-verified: removing releaseAbandonedSynchronizedOutput from schedulePaneRevealPresent fails the stranded-latch test. Two findings, both of which change previously-committed claims: 1. The 1s watchdog does NOT bound the synchronized-output defect. It is armed only inside `bufferRows`, and `refreshRows` returns at its `_isPaused` check first — so while a pane is occluded nothing reaches `bufferRows` and no timer is ever pending. A pane hidden mid-`?2026h` holds the latch with no watchdog behind it, indefinitely. ed1eaf55f1's "closes a bounded window" scope note was wrong; this is the unbounded garble the report describes, and the fix closes it. Corrected in the module doc comment. 2. It refutes the diff-based-staleness hypothesis behind0f7ec4458d(reverted in8d5eacecb4). `_updateModel` does early-continue per unchanged cell, but `GlyphRenderer.render` then copies vertices for EVERY row up to `lineLengths[y]` and issues ONE full-viewport draw — measured identical instance counts (562) for a diff-skipped and a model-cleared refresh, with updateCell at 0 vs 561. The DOM renderer likewise replaceChildren()s every row unconditionally. Clearing the model could not change what reached the screen, and `_clearModel(true)` zeroes every glyph vertex while `RenderService.clear()` fires no repaint of its own — so it opened a blank-viewport window (also asserted here) for no benefit. Also keeps the idle-agent and headful desktop-hide cases from the reverted commit, since those were independent of the refuted production change, and rewrites the alt-screen spec header to point paint questions at this oracle.
