# bin.mjs.map and main.cjs.map, ~12 MiB — are deliberately still built and still shipped, so

 # bin.mjs.map and main.cjs.map, ~12 MiB — are deliberately still built and still shipped, so

 # Issue #53's compensating control, and the reason the exclusion list above is safe to grow.
 #
 # The fork now excludes roughly half the asar. The failure mode of one bad glob is a
 # MODULE_NOT_FOUND thrown by a shipped app, on a path that may not run until a user signs in,
 # days after a green release. So this reads the artifact that is about to be published, resolves
 # every bare import in the packaged first-party bundles against what actually survived, and fails
 # if any of them is not loadable — whether or not a fork glob can be blamed for it. Severity does
 # not depend on attribution: a bundle that imports what it does not contain is broken either way,
 # and an earlier draft that warned on unattributed gaps passed a build that could not start.
 #
 # Runs on BOTH platforms: the Windows bundle unpacks node_modules outside the asar (the checker
 # merges app.asar.unpacked back in) and its graph differs (WSL backend, Linux fff binaries), so a
 # mac-only check would not cover it.

files upstream has never seen and cannot conflict.

Issue #53: `DESKTOP_FILE_EXCLUSIONS` appends `process.env.T3X_DESKTOP_FILE_EXCLUSIONS` (comma-separated globs), taking the packaged asar from 189.66 MiB / 14,765 files to 99.02 MiB / 3,429 and the `.zip` users download by 20.1 MB. Most of the added lines are the comments explaining both. Env hooks rather than changed literals on purpose. For #53 the reason is not row count — `build-desktop-artifact.test.ts` is already a row (see #71 above) — but that the fork's list is **67 globs and grows**: an inline list would make every future size fix an edit to an upstream TEST assertion, resolved by hand at every sync. Through the environment, an unset environment packages precisely what upstream packages and upstream's `deepStrictEqual` keeps passing untouched. Guarded from the fork side by `scripts/coil/mac-signature.test.ts` and `scripts/coil/desktop-bundle-size.test.ts` (both hooks exist, the release workflow sets them, the exclusions never name a package the main process loads) and by two artifact checks: `verify-mac-signature.ts` and `verify-desktop-bundle.mjs` (the shipped app still resolves every import its own bundles make) |
