## Fixed Issues
| Issue | File:Line | Commit |
|-------|-----------|--------|
| String-match error discrimination replaced with typed `ReadOutcome` enum | `walk.rs:183` | `18d3bfb` |
| Vec pre-allocation for `files` and `skipped` in `walk_and_read` | `walk.rs:100` | `18d3bfb` |
| SHA-256 hex encoding replaced with const NIBBLES lookup table | `walk.rs:282` | `18d3bfb` |
| Compile-time assertion for `MAX_FILE_BYTES <= usize::MAX` | `walk.rs:34` | `18d3bfb` |
| Hoisted `SKIM_DEBUG` env var check outside `par_iter()` hot path | `index.rs:265` | `0c2cc7d` |
| Eliminated `path_keys[idx].clone()` with `std::mem::take` | `index.rs:221` | `0c2cc7d` |
| Added TooLarge skip reason test coverage | `walk_tests.rs` | `052abf2` |
| Added incremental cache-hits verification via manifest comparison | `index_tests.rs` | `052abf2` |

## Simplification Pass
| Change | File | Reasoning |
|--------|------|-----------|
| `ReadOutcome::Ok` renamed to `ReadOutcome::Content` | `walk.rs` | Avoids shadowing `std::result::Result::Ok` |
| `ReadOutcome::TooLarge` now carries `u64` actual size | `walk.rs` | Reports real file size instead of sentinel value |
| Collapsed redundant assert + if-let in test | `walk_tests.rs` | Dead code path eliminated |
| Trimmed verbose test comment to 2 lines | `index_tests.rs` | Implementation detail belongs in source, not test |

## Issues Excluded (reviewer noted "no action needed")
| Issue | Reviewer | Reason |
|-------|----------|--------|
| `build_index` function length (90 lines) | complexity | "No immediate action required — acceptable for pipeline orchestrator today" |
| Argument parsing style diverges from siblings | consistency | "Acceptable modernization step — aligns with main CLI pattern" |
| Manifest `lang` field format change | regression | "Acceptable as-is — field is informational only, cache hits use sha256" |
| Implicit ordering in max_files test | testing | "Actually good test design — no change needed" |
