+# Guards against the committed solitaire_server/web/pkg/ artifacts going stale.
+#
+# A fresh build on a pinned toolchain is byte-for-byte reproducible (verified),
+# so this job rebuilds the artifacts and fails if they differ from what is
+# committed. Unlike a changed-files heuristic, this catches *any* drift in the
+# wasm-feeding crates — solitaire_core / _engine / _data / _sync / _wasm / _web —
+# including gameplay-logic changes that do not alter the JS API surface (e.g.
+# the v4->v5 save-schema change that the old heuristic let through as a
+# non-blocking "notice", leaving the deployed web build stale for ~3 weeks).
+#
+# Tool versions are pinned to whatever produced the committed artifacts. When
+# you regenerate the artifacts with a newer toolchain, bump these in lockstep:
+#   rust 1.95.0 · wasm-bindgen 0.2.120 · wasm-pack 0.14.0 · binaryen 130
