…2026.10.26.2) 2026.10.26.1 linked every POSIX output to $out.tmp and renamed it. Emscripten names the files it writes beside the output after the output, so a link to app.js.tmp wrote no app.wasm: the edge's implicit output was missing and mcpp pack of a wasm32-emscripten program found no stem family (mcpp-plugins' dist-web). A WebAssembly link is in place, as a PE link is. Co-authored-by: speak-agent <248744407+speak-agent@users.noreply.github.com>
…e format, mcpplibs.os, and part 1's closure Co-authored-by: speak-agent <248744407+speak-agent@users.noreply.github.com>
…_paths is per package (#844) A GCC module map now names the BMI directory as its repository ($root) and every path below it, so a BMI built with GCC's own mapper and one built with a map record their imports at the same paths: an indirect import, and `import std.compat`, are found in a unit with a map. A dependency BMI an earlier mcpp cached spells its imports the earlier way, so the cache key of a package that provides a module under GCC carries the spelling (the upgrade lane's `modules` variant). The dyndep step reads $root. The `trim_paths` prefix map left the flags every unit shares: a unit carries the fixed roots and its own package's closure, so switching workspace members no longer recompiles their common dependencies (e2e 872 F).

…dep step does A staged BMI's edge waits for the modules its map names, and the backend read the map line by line: `$root gcm.cache' became a module named `$root' and every path lost its repository, so the edge waited for `local-dev.gen-dep/gen.dep.table.gcm' beside the build directory (e2e 849). It reads the map with parse_module_map now. Co-authored-by: speak-agent <248744407+speak-agent@users.noreply.github.com>
…conditional; a closed reader ends mcpp in order The platform constants and architecture, the executable's name, PATH lookup, directory links, no-replace renames, volume identities and terminals come from mcpplibs.os. What it does not carry -- the launchers and their signal guard, flock-compatible file locks, durable sync -- is one implementation unit per system, selected by modules/platform/mcpp.toml. openkal ignores SIGPIPE for its own writes, and the ignore survived exec into every program mcpp started; std::print to a closed stdout threw. mcpp installs a SIGPIPE handler first thing: it ends mcpp as an interrupt does, then by the signal (141), and exec resets it for children. e2e 941.

…d, run by okrun, packed as the image (M2) or a program that carries it (M3) The triple names no operating system (<arch>-unknown-none-elf); the convention's flags and an ld.lld link produce an ET_DYN entered at ok_main; okld note and okld check, programs of the graph, finish each image before it takes its name. okrun is the target's runner. The target side's kernel-abi is fixed to openkal; every layer above it is the graph's, and the payload's libc++ is withheld. e2e 942; unit Triple.OpenkalIsAnImageForNoOperatingSystem.

2026.10.26.1 published every POSIX link through
$out.tmpand a rename (D22). Emscripten names the files it writes beside the output after the output, so a link toapp.js.tmpwrote noapp.wasm: the edge's implicit output was missing andmcpp pack --format web --target wasm32-emscripten(mcpp-plugins'dist-web, found by mcpp-plugins#51's CI) failed withno action claimed --format 'web'. A WebAssembly link is now in place, as a PE link is.Verified locally with emsdk 6.0.9: mcpp-plugins' web-consumer
