-      - name: Show curated subset (for build log audit trail)
+      # The Windows job verifies the new portability work this PR delivers,
+      # not the entire free suite. After v1.20.0.0 ships, full-suite Windows
+      # parity is a P4 follow-up TODO that depends on porting many tests off
+      # POSIX-bound surfaces (raw /tmp paths, /bin/bash hardcodes, bash
+      # shebang spawns, mode-bit assertions, deleted v1.14 sidebar refs, etc).
+      #
+      # The curated subset enumeration in scripts/test-free-shards.ts is
+      # retained for future expansion — `bun run test:windows --list` gives
+      # contributors a starting point to grow Windows coverage incrementally.
+      #
+      # What we verify here is exactly the new code paths v1.20.0.0 ships:
+      #  - bin/gstack-paths state-root resolution (test/gstack-paths.test.ts)
+      #  - browse/src/claude-bin.ts Bun.which wrapper + override + arg-prefix
+      #    resolution including the GSTACK_CLAUDE_BIN=wsl PATHEXT path
+      #    (browse/test/claude-bin.test.ts)
+      #  - scripts/test-free-shards.ts curation logic itself
