The bridge's own drawing no longer triggers its own re-read (#1707) - #1709
Merged
Conversation
The corner panel is redrawn on every survey and the Driver overlay on every log line, both under the observed root, so each survey's redraw was the next survey's trigger: a full survey about four times a second, forever, on a page where nothing had changed. The observers are now paused around the script's own writes, which keeps the rule that any page change triggers a re-read. check.mjs proves it: one page change costs exactly one survey (5 on the code before this).

#1707 item 2. The corner panel is redrawn on every survey and the Driver overlay on every log line, both under the observed root — so each survey's redraw was the next survey's trigger: a full survey about four times a second, forever, on a page where nothing had changed.
The observers
watchruns are now paused around the script's own writes (ownWrites, re-entrant; a dead context's observer is dropped from the set). This keeps the rule that any page change triggers a re-read; only the bridge's own drawing stops counting as one.check.mjs: "one page change costs one survey" — 5 surveys on the code before this, 1 with it; fails again with the pause disabled.
content.SPEC.md(watching) andcheck.SPEC.mdupdated.Live, in a claude.ai/code tab: before the reload the collapsed panel was rewritten with nothing changing (6 mutation records in 3 s); after it, 0 records in 5 s, and one page change → exactly one redraw (2 records), then 0. The Driver tab picked the new script up on its next page load.
