# Common form modules

## Proven form facts

The `test2` common forms `t_Форма` and `tt_Форма3` are distinct objects with
distinct GUIDs and descriptors. A label must be decoded from the descriptor;
do not shorten or normalize it by guesswork (`tt_Форма3` is not `t_Форма3`).

A form `.0` payload can contain more than a simple standalone BSL string. The
adapter must use the proven container extractor and preserve all non-BSL
segments, including form settings and command metadata.

## Module patch rules

- Obtain the BSL region from the decoded container, not from a global text
  search over compressed bytes.
- Count the requested anchor in the relevant BSL region.
- Replace a unique exact fragment once; report ambiguity otherwise.
- Re-encode using the source payload’s detected codec and line-ending style.
- Read back, re-extract BSL, and verify the target occurrence count.

## Pending-state resolution

When `ConfigCASSave` contains a `__configinfo` map, that map is authoritative
for the pending overlay even if the corresponding module row is absent. The
active `ConfigCAS` source must be selected through the saved map before a new
delta row is created. Reading only active content can incorrectly conclude
that a pending comment is absent and cause a duplicate insertion.
