Compiler: Emscripten 6.0.12, current stable checked on 2026-10-09.

Engine source/search policy/model bytes are unchanged. The WASM main
stack capacity changes from the 64 KiB default to 4 MiB. Emscripten 6's
incoming API list explicitly preserves verified WASM injection, the pthread
module URL and existing initialization hooks. Original threaded
pool expression, hash limits, search budgets, full resources and variants remain.
Corresponding build command: pwsh -NoProfile -File scripts/build-reversi133.ps1
Install isolated emsdk 6.0.12; the helper uses an owned cache and Node 26.11.1.
GPL-3.0-or-later upstream and original bridge/build sources remain in this archive.
