Module outline 

ct-outline’s heuristic declaration detection.

A rule pack per language turns a file’s text into ordered Entry rows — kind, name, 1-based start:end span, and nesting depth. Detection is line-pattern matching plus a block heuristic per language family: brace matching for Rust (over comment/string-stripped text), indentation for Python, heading levels for Markdown (fenced code blocks ignored). It is a comprehension aid, not a parser: start lines are exact; an end the heuristic cannot derive is None (rendered start:?), never a guess.
