Implementation Details

Code Structure

crates/terraphim_agent/src/main.rs
  Line 88-94:   BoundaryMode enum (None, Word variants)
  Line 97-101:  is_word_boundary_char() helper
  Line 104-127: is_at_word_boundary() helper
  Line 131-142: format_replacement_link() helper
  Line 418:     --boundary CLI argument
  Line 831-870: Replace handler boundary filtering

Design Decisions

Post-filter approach: Since automata doesn't support native word boundaries, matches are filtered after retrieval
Reverse order application: Replacements applied in reverse position order to preserve indices
Character classification: Alphanumeric and underscore are non-boundary characters

Edge Cases Covered

| Edge Case | Test | Behavior | |-----------|------|----------| | Start of string | test_is_at_word_boundary_start_of_string | Treats as boundary | | End of string | test_is_at_word_boundary_end_of_string | Treats as boundary | | Embedded in word | test_is_at_word_boundary_not_at_boundary | Returns false | | Punctuation | test_is_at_word_boundary_with_punctuation | Treats as boundary | | Partial boundary | test_is_at_word_boundary_partial_boundary | Returns false |

Verification Report: Commit-msg Hook Fix

Status: Verified Date: 2026-01-20 Commit: 2e44ea5c

Summary

Fixed the commit-msg hook to properly handle multiline commit messages by extracting only the subject line for validation.

Requirements Traceability

| Requirement | Design | Code | Test | Status | |-------------|--------|------|------|--------| | Extract subject line only | Use head -n1 on file | scripts/hooks/commit-msg:39 | Manual test | PASS | | Validate conventional format | Regex pattern | scripts/hooks/commit-msg:60 | Manual test | PASS |

Code Change

- subject_line=$(echo "$commit_msg" | head -n1)
+ subject_line=$(head -n1 "$commit_file")

Verification Test

# Test with multiline message
echo -e "test: validate multiline message support\n\nThis is a test body." > /tmp/test.txt
./scripts/hooks/commit-msg /tmp/test.txt

# Result: Validates only "test: validate multiline message support"
# Exit code: 0 (success)

Gate Checklist

[x] Subject line extraction verified
[x] Multiline message handling verified
[x] Output shows "Subject line:" not full message
[x] Hook installed in .git/hooks/
