Main's rule of 6 October 2026 from the 0.3.14 repro (docs/evidence/reproduced/0.3.14.md): prost's protowire.rs embeds OUT_DIR,
libmimalloc-sys embeds __DATE__/__TIME__, sccache hid both. lib.sh bs_repro_env exports SOURCE_DATE_EPOCH=<author time> TZ=UTC in
front of every remote command (build-remote.sh, cross-remote.sh, workers-remote.sh); remote-run.sh exports BR_SDE too and logs it
as source_date_epoch; proto-cuda/windows-node/cross-build.sh exports the same; the PC job carries node.commit_time in the manifest
(push-build-inputs.sh) and exports it before every cargo build of a stage (jobbuild.rs, unit test asserts it; 4 of 4 pass on the
box). Target dirs stay one fixed path per target. tools/build-remote.sh --self-test-repro [--full] from a fork worktree, run on
the box: igneum-miner twice a minute apart without sccache (RUSTC_WRAPPER=/usr/bin/env, an empty value is unset to cargo) MATCH
91e130f5..., a per-run target path differs (OUT_DIR shown); --full: kaspad with libmimalloc-sys recompiled a minute later MATCH
70219bc2..., without the epoch differs (__DATE__ shown).

Main's decision of 6 October 2026. CLAUDE.md 'Running agents on this Mac': every Linux and Windows cargo build and every
Linux test suite goes to igneum-build-1 through tools/build-remote.sh and tools/cross-remote.sh; the PCs keep GPU and
Windows-runtime jobs; the Mac keeps macOS binaries, the DMG and Metal tests under the lock. -Wl,--no-insert-timestamp in
cross-remote.sh, proto-cuda/windows-node/cross-build.sh and jobbuild.rs (two box builds byte-identical, verified).
The empty-commit class: tools/ci/commit-string-check.sh (self-test in ci.yml, shown firing on a Mac worktree build and
passing on a box build) runs on every igneumd from the three build scripts; push-build-inputs.sh adds node.commit_full,
the PC job writes a minimal node/.git from it at extract and cleans kaspa-build-info on a new commit (4 jobbuild tests
pass, run on the box); cross-build.sh refuses a worktree and cleans on a new commit. Plan: second worktree's clean build
1 min 18 s with sccache 604 hits of 993.

0.3.6 on both PCs: igneumd.exe (built on PC 1 with GCC 13's mingw) shipped with the Mac toolchain's GCC 16
libstdc++-6.dll, which no longer exports seven symbols the exe imports (std::codecvt_utf8_utf16 and a
stringbuf::seekpos); Windows refused the node with Entry Point Not Found. -C link-arg=-static had never removed
the libstdc++ import (0.3.5's Mac-built exe carries it too).
- packaging/windows/check-runtime-dlls.sh: objdump imports per DLL against the DLL's exports; shown to fail
the 0.3.6 pairing (7 missing) and pass 0.3.5's; run by push-inputs.sh before signing and by make-payload.sh
- push-inputs.sh: DLLs next to the exes first, then the Mac toolchain
- jobbuild.rs: the PC's windows stage copies its own toolchain's three DLLs into the pack (unit test);
build-job.mjs accepts the small DLL PE files and places them next to the exes
- cross-build.sh: -static-libstdc++ added as a try (measured on the 0.3.7 build)
- the six version files: 0.3.7
proto-cuda/windows-node/: START-NODE.bat and start-node.ps1 (igneumd
--devnet with --addpeer to the Mac, status line every 30 s through
igneum-miner watch, keep-awake, random-delay restart, Ctrl+C),
BUILD-NODE.bat and build-node.ps1 (builds on the PC from the src.zip
snapshot; winget for Rustup, LLVM and protoc; MSVC default toolset),
ALLOW-FIREWALL.bat and allow-firewall.ps1, README.txt, cross-build.sh
(the mingw-w64 recipe that built igneumd.exe in 8 min 25 s; the exe
ships with the three mingw runtime DLLs) and make-package.sh.
WINDOWS-MINER.md gains "Run your own node"; bench-log records the
cross-compile and the two-peer sync test on the Mac (ports 27000 and
27010, live node untouched). The mining launcher's NODE_HOST=auto
edit stays uncommitted for the agent that owns start-mining.ps1.
