- default icon src/runtime/punk1.ico, per-kit override from the kit's .vfs; mechanism per tcl-sfe (TEMP_REFERENCE/tcl-sfe, Ashok P. Nadkarni): RT_ICON/RT_GROUP_ICON replacement via twapi resource-update APIs, ordered so the appended vfs payload stays intact (icon stub before append, or sfe-style split/update/reattach)
- detail file records the _vfscommon.vfs override-detection wrinkle (common punk1.ico merges into every built vfs - consult the custom pre-merge folder or an explicit mapvfs.config element), idempotence via delete-then-write, twapi/non-Windows skip path, and resource-inspection acceptance
- follow-on candidate flagged (detail file only): RT_VERSION stamping - copyright defaulting to the input runtime's own version-resource copyright, Product Name indicating the core Tcl version by default, both configurable via punkproject.toml and/or per-vfs config
