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