# Reliability Review Report

## Issues in Your Changes (BLOCKING)

### CRITICAL

(none)

### HIGH

(none)

### MEDIUM

**Misleading doc comment cross-reference in `compute_line_range`** - `crates/rskim-search/src/types.rs:364`
**Confidence**: 85%
- Problem: The doc comment on `compute_line_range` states it returns ranges "matching the convention used by [`SearchResult::line_range`]". However, `SearchResult::line_range` (line 331) is documented as "0-indexed, exclusive end", while `compute_line_range` returns **1-indexed**, exclusive end ranges. The cross-reference implies 0-indexed when the function actually returns 1-indexed. This creates a misleading contract for callers who read the `SearchResult` doc and then trust the cross-reference.
- Fix: Either update the `SearchResult::line_range` doc comment to say "1-indexed, exclusive end" (if that is the intended convention going forward), or remove the misleading cross-reference from `compute_line_range` and instead state the convention directly:
```rust
/// Returns `min_line..(max_line + 1)` (1-indexed, exclusive end).
```

## Issues in Code You Touched (Should Fix)

(none)

## Pre-existing Issues (Not Blocking)

(none -- the `SearchResult::line_range` doc comment inaccuracy at line 331 predates this PR, but the new code introduced a cross-reference that amplifies the inconsistency, so it is reported as Blocking above)

## Suggestions (Lower Confidence)

- **Duplicate `byte_offset_to_line` implementations** - `crates/rskim/src/cmd/search/snippet.rs:47` and `crates/rskim-search/src/types.rs:351` (Confidence: 70%) -- Two identical implementations exist: the original `pub(super)` version in `snippet.rs` (returns `u32`) and the new `pub` version in `types.rs` (returns `usize`). The snippet version is still used on line 160 for `match_line` (which needs `u32` for `extract_context_window`). Consider having `snippet.rs` call the library version with a `u32` cast, reducing duplication to a single source of truth.

- **Growing positional tuple in `SnippetOutcome::Ok`** - `crates/rskim/src/cmd/search/snippet.rs:32` (Confidence: 65%) -- `SnippetOutcome::Ok(u32, Range<usize>, SnippetContext)` is a 3-element tuple variant. Each new field added to the success path makes destructuring harder to read and more error-prone (field order matters, no names). A named struct variant would make the fields self-documenting.

## Summary

| Category | CRITICAL | HIGH | MEDIUM | LOW |
|----------|----------|------|--------|-----|
| Blocking | 0 | 0 | 1 | 0 |
| Should Fix | 0 | 0 | 0 | 0 |
| Pre-existing | 0 | 0 | 0 | 0 |

**Reliability Score**: 8/10
**Recommendation**: APPROVED_WITH_CONDITIONS

The new utility functions are well-bounded: offset clamping prevents panics, the empty-input guard returns a sentinel `0..0`, and `#[must_use]` enforces that callers consume the return values. The 5 MB size guard in `extract_snippet` (pre-existing) ensures the linear newline scan in `byte_offset_to_line` operates on bounded input. Test coverage is thorough with edge cases (empty content, out-of-bounds offsets, single line, multi-line spans). The one condition is the misleading doc comment cross-reference, which should be corrected before merge to prevent callers from misinterpreting the indexing convention.
