Feature: Repo Indexing Utils Coverage
  Scenarios that exercise previously uncovered code paths
  in repo_indexing_utils.py (lines 118, 175, 266, 268, 269,
  274, 281, 285, 286, 292-296, 306-307, 312, 338-342).

  Background:
    Given the repo indexing utils module is imported

  # --- detect_language: Dockerfile special case (line 118) ---

  Scenario: detect_language identifies Dockerfile by basename
    When I detect the language for path "Dockerfile"
    Then the detected language should be "dockerfile"

  Scenario: detect_language identifies Dockerfile with suffix
    When I detect the language for path "Dockerfile.prod"
    Then the detected language should be "dockerfile"

  Scenario: detect_language identifies Makefile by basename
    When I detect the language for path "Makefile"
    Then the detected language should be "makefile"

  # --- _glob_match with ** or / in pattern (line 175) ---

  Scenario: matches_policy uses recursive glob with double-star pattern
    When I check matches_policy for "src/utils/helpers.py" with include glob "**/*.py"
    Then the path should match the policy

  Scenario: matches_policy uses path-based glob with slash in pattern
    When I check matches_policy for "src/utils/helpers.py" with include glob "src/utils/*.py"
    Then the path should match the policy

  Scenario: matches_policy rejects path not matching recursive glob
    When I check matches_policy for "src/utils/helpers.py" with include glob "**/*.rs"
    Then the path should not match the policy

  # --- walk_and_index: hidden directories filtered (lines 266, 268, 269) ---

  Scenario: walk_and_index skips hidden directories and special directories
    Given a temporary directory with hidden and special subdirectories
    When I run walk_and_index on the temporary directory
    Then only files from visible non-special directories should be indexed

  # --- walk_and_index: hidden files skipped (line 274) ---

  Scenario: walk_and_index skips hidden files
    Given a temporary directory with hidden files
    When I run walk_and_index on the directory with hidden files
    Then hidden files should not appear in the results

  # --- walk_and_index: symlinks skipped (line 281) ---

  Scenario: walk_and_index skips symlinks
    Given a temporary directory with a symlink to a file
    When I run walk_and_index on the directory with symlinks
    Then symlinked files should not appear in the results

  # --- walk_and_index: ValueError on relative_to (lines 285-286) ---

  Scenario: walk_and_index skips files when relative_to raises ValueError
    Given a temporary directory with a file that will cause a relative_to ValueError
    When I run walk_and_index with mocked relative_to failure
    Then the file causing ValueError should be skipped gracefully

  # --- walk_and_index: path > 1024 chars (lines 292-296) ---

  Scenario: walk_and_index skips files with paths exceeding 1024 characters
    Given a temporary directory with a deeply nested file exceeding 1024 char path
    When I run walk_and_index on the deeply nested directory
    Then the deeply nested file should be skipped

  # --- walk_and_index: stat() raises OSError (lines 306-307) ---

  Scenario: walk_and_index skips files when stat raises OSError
    Given a temporary directory with a file that will cause a stat OSError
    When I run walk_and_index with mocked stat failure
    Then the file causing stat OSError should be skipped gracefully

  # --- walk_and_index: non-regular file skipped (line 312) ---

  Scenario: walk_and_index skips non-regular files like FIFOs
    Given a temporary directory with a FIFO named pipe
    When I run walk_and_index on the directory with the FIFO
    Then the FIFO should not appear in the results

  # --- walk_and_index: max_file_count cutoff (lines 338-342) ---

  Scenario: walk_and_index stops after reaching max_file_count
    Given a temporary directory with five regular files
    When I run walk_and_index with max_file_count of 2
    Then only 2 file records should be returned
