Addresses gitnexus-review-agent findings on PR #2608:
- MED: on a partial apply (a file's write throws), drop that file's edits
from total_edits/graph_edits/text_search_edits/changes so the reported
result describes what actually reached disk, not what was attempted. The
comprehensive enumeration otherwise let a failing file contribute its
entire line count as phantom 'applied' edits. failed_files still names
every dropped file. Counts are now derived once from the reported set.
- MED: hoist the word-boundary regexes out of the per-line loop (one compile
each instead of one per line), reused by the apply loop.
- LOW: apply loop reuses escapedOldName instead of recomputing the escape
formula inline (removes a preview/apply drift risk).
- Soften the in-code comment: enumeration gives per-call preview/apply
consistency; the pre-existing two-read TOCTOU (external write between
preview and apply) is out of scope and noted, not newly introduced.
Tests: add a mixed graph-ref + text_search multi-file case (asserts per-file
confidence and the never-downgrade guard, via a stubbed rg), and a
partial-write-failure case (asserts only landed files are reported). Assert
concrete graph_edits/text_search_edits splits, not just their sum.
rename() reported total_edits from a partial enumeration (definition line
only, one-edit-per-graph-file then break, and text search that skipped any
file already covered by the graph) while the apply step does a whole-file
\boldName\b global replace on every touched file. When a private symbol's
definition and all its call sites live in one file, only the definition line
was reported (total_edits: 1) even though apply rewrote every occurrence, in
both dry-run and apply.
Rebuild changes/total_edits/graph_edits/text_search_edits from one file set:
classify each file to rewrite (definition + graph refs = graph confidence;
rg-only files = text_search, never downgrading a graph file), then enumerate
every matching line per file with apply's exact escaped global regex. The
reported edit list now equals what apply writes. Apply behavior is unchanged.
Adds a regression test reproducing the issue's single-file Rust case (def +
3 same-file call sites, empty graph): total_edits is 4 in both dry-run and
apply, and equals the replacements that land on disk.
