## Narrative

**Business context:** Integer-typed sibling of `FUN_JSON_CHAR`. Reads a key out of a JSON payload and casts to signed int. Designed for the same `sp_btn_action` button-event dispatcher to evaluate flag fields (`bSubmit`, `bCheck`, `bTecnologe`, …).

**What it does:** If `sParam` is valid JSON, extracts `sKey`, strips quotes, casts to signed integer; defaults to 0.

**Invocation:** Orphan-via-dead-chain. Only callers are `sp_btn_action` + `sp_btn_action_updatequoquotationslave`, both themselves orphans (no form-master, module-hook, or Java reference anywhere). Candidate for maintainer audit.
