+Grep can't tell **which class/method** a hit inside a `.vc2` belongs to (the class header may be
+thousands of lines above it, and ~2/3 of the file is properties/metadata). `vfp_symbols.ps1`
+indexes the line range of every class/method/procedure and labels hits with their owner — use it
+before any `txt2vcx.ps1` edit to get the exact line range of the method you are changing. Its
+built-in defaults target ROAACNPRO, so always pass this project's paths:

+The index (`_symbols.tsv`) rebuilds itself when the text is newer, so refresh the text first — it
+can't see IDE edits that were never converted. Full search guide: `COMUN\docs\cautare_vcx_vct.md`.

 `COMUN/` is excluded from this repo's git — it is shared by every ROA product and versioned by its
 **own git repo**, `gitea.romfast.ro:romfast/comun.git`. Run git commands for `COMUN/` from inside
 that directory, and treat any change there as cross-project.
