The 2026.10.28.1 release: what the ecosystem check of 2026.10.27.1 found.

• SPEC-014 1.2: a package name carries a mode's suffix (-bundle-all for self-contained), a single file's launcher exits 127 on its own failure, --merge takes its container from [pack] format before -o, and --linkage static moves this machine's row and each -linux-gnu --target to musl while a project's own [build] target is packed as it is.
• mcpp emit xpkg --package: packages of several systems may place the program apart (openkal-image 0.1.3's okrun: okrun.exe at the root on Windows, bin/okrun elsewhere). The entry registered the first package's directory for every system; it now writes bindir[os.host()] from each system's directory when they differ. A word past the options (--package a.zip b.zip, a shell glob) was silently left out; it is refused with the repeated form. The install looked its directory up with os.dirs("<name>-0.1.3-*"), which libxpkg's os.dirs (it lists <base>/*, no name matching) never matched: no xlings install of an emitted entry succeeded. The directory is now the downloaded archive's name without its extension (as mcpp pack names it), valid for every system, architecture and later version; a renamed archive or a non-archive is refused. Verified in a clean XLINGS_HOME: okrun, okld and a universal package installed from emitted entries and run. The runner dependency is written xim:okrun: xim-pkgindex's check-dep-namespace refuses a bare name once the package is published. Unit XpkgDescriptorNamesEachSystemsProgramDirectory; e2e 957 C.
• mcpp.run: a build ended by SIGTERM could exit 1 instead of 143 when the main thread, woken by its killed compiler, returned from main before the watcher ended mcpp (main CI 40671515047, e2e 936 H, the cancelled record in place). finish() runs once with later callers waiting for it, and main ends with end_if_requested().
• Cache key: the provider of each module a package imports is an upstream of its key, a declared edge or not. The libraries of a build program import the engine interface (mcpp), which no manifest names; mcpp.plugins was served an entry compiled against another interface ("import 'mcpp' has CRC mismatch", measured in an ok-image build over a warm cache). An import a declared path runs the other way (a module generated for a dependency below its consumer, e2e 849) is not one. New e2e 959 (fails before, passes after); ci-upgrade gains a programs variant (an ok image over the previous release's cache).
• archive_directory() is the one rule a package's directory takes from its archive (pack -o, --merge -o, emit xpkg); --merge -o names the merged directory after its output; emit xpkg reads .tgz.
• finish() reached again from inside a cleanup returns at once.
• upgrade-lane-logs/ (committed with 2026.10.17.1) leaves the tree and is ignored.
• bump_index.sh: the updater opens auto/bump-xim-<project> (no version in the branch), so the release waited for a branch that never appears; the PR is found by its xpkgindex-update marker (open or merged). A refused dispatch names the permission the token lacks (Actions: write on openxlings/xim-pkgindex) and the command a maintainer runs. publish-ecosystem has failed at this step since 2026.10.24.1 (403 on the dispatch).
