Maestro Daily: Chasing Ghosts in Scroll and Auth Resume
Two rounds of fixes landed this week that share a pattern - both scroll restoration and agent resume failures were caused by state being checked once instead of verified until it actually settled. A third theme saw the team pulling dead code and gating a new protocol client behind conformance tests before it ships.

Good day, and welcome to Maestro Daily for September 4th, 2026.
The clearest signal today: two separate bugs, scroll restoration and agent resume after re-authentication, both traced back to the same mistake - checking state once and assuming it was final, instead of confirming it actually stuck.
Start with scroll. PRs 1489 and 1490 fixed chat transcripts and file previews landing above where users left them. The saved offset was always correct - the restore was the problem. It measured page height in a single animation frame, before images, fonts, or markdown finished rendering, so it clamped to a too-short…
The same "verify, don't assume" lesson shows up in PRs 1494 and 1495 around Resume Agent. The investigation initially suspected the error parser was broken - author pedramamini tested that against real captured data and found it wasn't. The actual bug: re-auth snapshots lived only in memory, and quitting the app…
Elsewhere, PR 1497 fixed a related mix-up: a passive tab-sync broadcast was being treated the same as an explicit user tab selection, occasionally stealing focus from the active agent. Same class of bug - conflating two different signals on one channel.
On the cleanup…
