31// ## Note on `.unwrap()` / `.expect()` usage
32//
33// The remaining `.unwrap()` and `.expect()` calls in `src/` are in:
34// - **Tree-sitter query operations** (parser.rs, zoom.rs, extract.rs, inline.rs,
35//   outline.rs): These operate on AFT's own compiled grammars and query patterns, which
36//   are compile-time constants. Pattern captures and node kinds are guaranteed to exist.
37// - **Checkpoint serialization** (checkpoint.rs): serde_json::to_value on known-good
38//   HashMap<PathBuf, String> types cannot fail.
39// - **lib.rs main loop**: JSON parsing of stdin lines — a malformed line is logged and
40//   skipped, not unwrapped.
41//
42// All production command handlers that process user/agent input return Result or
43// Response::error instead of panicking. Confirmed zero .unwrap()/.expect() in
44// production error paths as of v0.6.3 audit.
