Pack	F_OVERLAY — Industry Overlay and Compliance
Title	GD&T feature control frames must be syntactically complete per ISO 1101
Severity	major
Check logic	Deterministic
Applies to	Compliance overlay
Inputs required	datum_scheme
Fix template	Fix malformed GD&T callouts so each frame includes the required ISO 1101 fields (symbol, tolerance value, and required datum references/modifiers).

Short Description

Flags incomplete or non-parsable GD&T feature control frames (missing tolerance value, missing datum references where required, malformed symbols).

When It Applies

This rule runs only when an overlay activates F_OVERLAY. It targets Compliance overlay.
