Require the Flatpak sandbox marker.
FLATPAK_ID can remain in a host child-process environment. Line 79 then classifies a non-Flatpak installation as platform-owned. The update flow suppresses both self-update and release-page actions for that channel.

Use a download-specific error message.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Reject empty Semantic Version identifiers.
The regex accepts invalid values such as 1.2.3-rc..1, 1.2.3-rc., and 1.2.3+build.. parseVersion then normalizes and compares these invalid values.
Require at least one identifier character on each side of every period. Add these values to the rejection cases in electron/update-checker.test.ts.

Review feedback on #358. A failed downloadSelfUpdate() showed `updates.failed` — "Could not check for updates" — but the check is how we got there. Adds `updates.downloadFailed` across all 13 locales. Also pins the three updater settings that are the difference between an update and a lost recording, and that all read as deletable boilerplate: autoDownload and autoInstallOnAppQuit are off, and quitAndInstall is called with isSilent=false so a per-machine Windows install can show its UAC prompt. The mock starts from electron-updater's defaults so the assertions prove our configuration ran rather than reading untouched values.

The update metadata was already being generated on every build and thrown away at the upload step. This publishes it, adds the updater that consumes it, and — first — decides who is allowed to update at all. install-channel.ts is the load-bearing part. On the Microsoft Store, Flathub, Snap and Nix the package manager already updates the app, and a second updater there is not merely redundant: the MSIX install directory is read-only, and a "download the .exe" prompt walks a Store user into a SECOND, parallel installation that then drifts forever. Those channels get no update affordance at all. `dev` and `unknown` builds cannot self-update either but keep the release-page link, which is why "may we self-update" and "does a package manager own this" are two predicates rather than one. Artifacts, per platform: - Windows: latest.yml and the .exe.blockmap were built by every run and discarded, because the upload glob only matched the .exe. Differential updates were one glob line away. - Linux: app-update.yml and the package-type marker already ship INSIDE every deb/rpm/pacman, and the AppImage already carries its blockmap. Only latest-linux.yml was missing; one feed serves all four formats. - macOS: nothing was generated, because the pack step passes --dir, which skips every target. So the ZIP Squirrel.Mac requires is built with ditto from the signed .app, and named for the instruction set — electron-updater matches the literal substring "arm64", while our DMGs are named Apple-Silicon/Intel for the user. Getting that wrong serves Apple Silicon the Intel build with no error anywhere, so it is asserted in CI. The two macOS arches build on different runners, so neither job can write the feed: electron-builder would have each emit its own latest-mac.yml and the second upload would overwrite the first (electron-builder#5592, closed as not-planned). Each job emits a JSON sidecar; publish-release folds them into one feed listing both. The ordering and fallback rules live in a pure function with tests, because nothing else here can exercise them. The publish block is declared rather than inferred: app-builder-lib was falling back to reading .git/config's origin, which works in CI and silently stops working for anyone building from a source tarball — and a missing package-type marker makes electron-updater treat a .deb as an AppImage. Guards, all of which are the difference between an update and a lost take: autoDownload and autoInstallOnAppQuit are both off (window-all-closed quits this app and the HUD is a window, so the default would fire an installer on closing the HUD); installing is vetoed while recording, which on Windows is also a hard requirement because the capture helpers spawn from inside the install directory and NSIS cannot overwrite a running .exe; and on macOS an app outside /Applications is refused, because App Translocation runs it from a read-only image Squirrel cannot replace. The release-page fallback from #313 is kept rather than replaced. Every macOS install up to v1.9.0-rc.1 is ad-hoc signed, and Squirrel validates an update against the INSTALLED app's designated requirement — those users can never be reached by any updater and need one manual reinstall. Also fixes the lifecycle of the manual check itself: it was `void`ed, and main-process-errors re-throws every unhandled rejection, so a check that settled after quit could take the process down. Stacks on #313.
Review feedback on #358. A failed downloadSelfUpdate() showed `updates.failed` — "Could not check for updates" — but the check is how we got there. Adds `updates.downloadFailed` across all 13 locales. Also pins the three updater settings that are the difference between an update and a lost recording, and that all read as deletable boilerplate: autoDownload and autoInstallOnAppQuit are off, and quitAndInstall is called with isSilent=false so a per-machine Windows install can show its UAC prompt.

Review feedback on #358. The `configured` flag meant only the first caller set autoDownload/autoInstallOnAppQuit, so the test asserting they are false was passing on whichever test happened to run first rather than on its own call — reorder the file and it would have gone vacuous. Memoising three property writes buys nothing measurable, and the flag also meant anything that later reset them would never be corrected. Dropped it. The test now restores electron-updater's defaults in beforeEach and asserts from inside the checkForUpdates mock, so it pins that the settings are applied BEFORE the check runs — a check that starts downloading before autoDownload is off has already pulled ~243 MB nobody asked for.
The rebase onto main took main's hash for the conflicting line; the lockfile is now main's plus electron-updater, so neither side's value was right. nix-check.yml reported the expected one.

Gives every channel we distribute ourselves a real in-place upgrade path — the user is upgraded without re-downloading the app by hand — and, just as importantly, makes the app stay out of the way on the channels where a package manager already owns the update.
The finding that shaped this
The update metadata was already being generated on every build and thrown away at the upload step:
.exe.blockmapbuilt every run*.exe, so it andlatest.ymlwere discardedapp-update.yml+ thepackage-typemarker already inside every deb/rpm/pacman; AppImage already carries its blockmaplatest-linux.yml--dir, which skips all targets--publish neversuppresses uploading, not metadata generation. So Windows and Linux were one glob line each.Who is allowed to update —
electron/install-channel.tsThe load-bearing part, and the reason this isn't just a dependency bump.
On the Microsoft Store, Flathub, Snap and Nix the package manager already updates the app. A second updater there isn't merely redundant: the MSIX install directory is read-only, and a "download the .exe" prompt walks a Store user into a second, parallel installation that then drifts from the Store copy forever. Those channels get no update affordance at all — not a disabled one, not a link.
Detection is a pure decision table over an injected probe, so every platform's behaviour is testable from Linux-only CI. Order matters: the platform-owned markers are checked first, because they coexist with the self-owned ones — a Flatpak build still carries a
package-typefile, and a Snap still looks like a plain Linux install from the inside.process.windowsStore(trueor undefined, neverfalse)FLATPAK_IDand/.flatpak-infoSNAPandSNAP_REVISION(two, so a stray var isn't enough)execPathunder/nix/store/APPIMAGE<resourcesPath>/package-typeapp.isPackaged === falseis not sufficient on its own — Flatpak and Snap are packaged.Two predicates rather than one, deliberately:
ownsItsUpdates(may we replace ourselves) andplatformOwnsUpdates(should we show anything at all). Adevorunknownbuild can't self-update either, but pointing its user at the release page is still useful. Collapsing them would silently remove the only affordance those builds have — there's a test pinning that.macOS is the subtle one
ditto, notzip—zipflattens the symlinks inContents/Frameworksand drops xattrs, producing an archive whose.appfails the signature validation Squirrel performs against the installed app's designated requirement.filterFilesForArchmatches the literal substringarm64; our DMGs are deliberately namedApple-Silicon/Intelbecause that's what About This Mac shows. Naming the ZIP that way would hand every Apple Silicon client the Intel build, silently, under Rosetta. Asserted in CI and inarchOf().latest-mac.ymland the second upload would overwrite the first (#5592, closed as not-planned). Each job emits a JSON sidecar;publish-releasefolds them into one feed listing both. The ordering and fallback rules are a pure function with tests, because nothing else in this repo can exercise them.path/sha512fallback points at x64: an Apple Silicon Mac runs an Intel build under Rosetta, an Intel Mac can't run an arm64 build at all. Degrade to slow, never to broken."zip"is not added tomac.target— with--dirthat would be dead config that reads as if it worked. Commented in place so the next person doesn't try.Guards
Each is the difference between an update and a lost recording:
autoDownloadandautoInstallOnAppQuitboth off.window-all-closedquits this app and the HUD is a window, so the default would fire a ~243 MB installer when the user merely closed the HUD..exe./Applications— App Translocation runs a quarantined app from a read-only image Squirrel cannot replace, and an app can become translocated after an update and then never update again.What is deliberately kept
#313's release-page fallback stays, permanently. Every macOS install up to v1.9.0-rc.1 is ad-hoc signed, and Squirrel validates an update against the installed app's designated requirement — a Developer ID build will never satisfy it. Those users cannot be reached by any updater and need one manual reinstall. The fallback is also what covers
dev,unknown, and any release published before these feeds existed.Also fixed here
The manual check from #313 was
voided.main-process-errorsre-throws every non-EPIPE unhandled rejection, so a check that settled after quit could take the main process down. Now aborted onbefore-quitwith a terminal handler.Native code is updated too
Worth stating since it's a common misconception: this is not a JS-only patch mechanism. Every channel replaces the whole payload, so the Swift/C++ capture helpers, the Rust compositor addon, the ffmpeg libraries and the whisper binaries all come along. What does not come along is anything under
userData— recordings, projects, and the ~500 MB STT model are untouched.Testing

NsisUpdater.verifySignature()returnsnull(= OK) when there's nopublisherName. electron-builder v28 flips that to fail-closed, so this needs a certificate before then. Azure Trusted Signing is not an option (GA restricts individuals to US/Canada); Certum's Open Source cloud cert is €49/yr. Sign through electron-builder when it lands — post-hoc signing invalidates the blockmap.latest.ymlwon't advertise that elevation is required. Acceptable, but worth knowing.gh release upload --clobberbecomes riskier once a feed is published — treat release assets as immutable and re-cut instead.Summary by CodeRabbit
