…layed builds count; the retentions are set with `mcpp self config`; debug sections are compressed only by a toolchain built to - mcpp::home::mark_used sets the time of an entry's record file (entry.json, std-module.json) at most once in 12 hours; a package hit no longer rewrites entry.json; the collection reads the later of the stamp and the record's time - uses.list names the cache entries a configuration used, written once the plan is complete; the sweep after a build marks them used, so a build that replays its graph counts - `mcpp self config --cache-unused-days <N> --keep-days <N>` writes [cache] unused_days (30) and [build] keep_days (3); `mcpp self config` shows them - compresses_debug_sections asks the driver once (-gz=zlib -###) and keeps the answer: the Windows-hosted LLVM 23.1.3 has no zlib and its ld.lld refused the link (openkal-cross windows) - e2e 1000 D, E; 174 ages the record's time too Co-authored-by: speak-agent <248744407+speak-agent@users.noreply.github.com>

Summary
Fixed (found by mcppls-clangd#13). Under a platform with seal steps the link writes
obj/platform/<artifact>.unsealedand aplatform_sealedge publishes the artifact; the ordering guard of mcpp#702 took the seal edge for the link and refused every ok image whose graph declares aprepareaction.link_edge_outputnames the link edge's output for the emitter and the guard. e2e 996.mcpp#874 — a large workspace keeps its bytes once and builds each output once (design). Measured on mcppls (6 members, 61 test programs, clang):
bin/4 914 → 1 217 MiB, test links 75 → 32 s.-gz=zlib; an ok image'sld.lldlink compresses it), no measurable compile cost;split_debuginfo = "unpacked"(default of dev/debug) leaves the units compiled in the build directory beside their objects. Index packages' units stay in band (their objects enter the cache). Mach-O, PDB, MinGW, wasm and freestanding unchanged. e2e 999, 996 C.test --workspace, complete underbuild, polluted by dev-dependencies); action rules haverestat. e2e 997, 998 G.uses.listper configuration,clean --staleover.build-mcpp/outandhost,clean --report, a low-disk warning; the cache covers host tools, marks std/tool hits, supersedes a path tool's old stamps, and collects entries unused for[cache] unused_days(30). e2e 998.[build] keep_days(3) are swept. e2e 1000.CI: the macOS legs run on macos-15 (GitHub retires macos-14 on 2026-11-02); the floor stays macOS 14, asserted as the installed binary's minos.
