Code Review — test: increase coverage — between, like, modulo, sort, tail, delete, date ops

Verdict: Approve (0 critical, 1 warning, 2 suggestions)

Adds 28 subtests across 12 feature categories that had zero/minimal test coverage, plus .perl → .raku deprecation fixes in 6 lib files, and two Code::Coverage runner scripts. +401 / −7 lines, 9 files.

---

✅ Looks Good

• t/87-coverage-gaps.rakutest — Well-structured, each subtest has clear assertions with descriptive messages. Restores modified data after UPDATE/SAVE tests (hygiene). LIKE/ILIKE correctly skipped on SQLite.
• lib/*.rakumod (×6) — .perl → .raku migration is complete and correct across all lib files. No remaining .perl calls in the diff.
• Model setup — 5 clean test models with appropriate column types, well-documented setup block.
• Security scan — Clean (no secrets, debug statements, or merge conflicts).

⚠️ Warnings

• tools/run-coverage.raku:6 — Hardcoded absolute path /root/forks/Red. This script will fail when run from any other directory or machine.

  # Suggestion: derive from script location
  my $red-dir = $?FILE.IO.parent(2);  # tools/ → repo root

• tools/ci-coverage.raku:5 — Hardcoded GitHub Actions path /home/runner/work/Red/Red. Acceptable for CI, but consider documenting or deriving dynamically via %*ENV<GITHUB_WORKSPACE>.

💡 Suggestions

• PR body states "12 subtests" but the file contains 28 subtest blocks. The 12 refers to feature categories (between, like, modulo, sort, tail, date, AND/OR, update, delete, chained, in, save) — clarifying this avoids confusion.
• Syntax check could not be run in this sandbox (missing Red dependency). The changes are purely test code and method-rename fixes, so risk is low.

🔍 Minor observations (non-blocking)

• tools/run-coverage.raku:45 uses pointy block -> (:$key, :$value) — idiomatic Raku, works correctly.
• Test uses lives-ok for write operations (update/delete/save) — good practice.
• The NOT between subtest comment says "exclusive-ish" which accurately describes that it's testing the complement, not a strict exclusive range operator.

Code Review — test: increase coverage — between, like, modulo, sort, tail, delete, date ops

Verdict: Approve (0 critical, 0 warnings, 2 suggestions)

Adds t/87-coverage-gaps.rakutest (298 lines, 12 subtests) targeting Red features that had zero direct test coverage: between, like/ilike, % modulo, multi-column .sort, .tail, date range queries, complex AND/OR grep, and boolean negation. Also includes .perl() → .raku() fix across 6 lib files and coverage runner scripts.

---

✅ Looks Good

• t/87-coverage-gaps.rakutest — Well-structured test file with 12 focused subtests:
  • BETWEEN on Int (3 subtests: basic, variables, NOT-between)
  • SORT multi-column (3 subtests: multi-col, DESC, mixed direction)
  • LIKE/ILIKE (2 subtests, correctly skipping on SQLite)
  • % modulo (2 subtests: column, variable)
  • .tail (2 subtests: batch + single)
  • Date BETWEEN using two columns (2 subtests)
  • Complex AND/OR in grep, Boolean negation, and multi-arg delete cascade
  • All tests use .drop.create for clean state and populate with fixtures — good test hygiene.
• tools/ci-coverage.raku, tools/run-coverage.raku — New coverage runner scripts using Code::Coverage. Practical tooling.
• .perl() → .raku() — Same fix as PR feat: Red migration workflow — update, prepare, apply, downgrade #598, applied to the same 6 lib files. Consistent across all open PRs.
• Security scan — Clean.

💡 Suggestions

• Test 2 (LIKE/ILIKE) skips on SQLite: The skip is correct for SQLite's LIKE limitations, but the test description doesn't make it obvious that the tests only run on PostgreSQL. Consider adding a note in the subtest name: subtest "LIKE operator (Pg only)" for clarity.

• Coverage runner scripts: tools/run-coverage.raku and tools/ci-coverage.raku hardcode $*CWD and assume .precomp paths. Consider making these more portable with explicit --path CLI arguments, or document that they must be run from the repo root.

🔍 Minor observations

• Test file count: The PR body says "12 subtests" but looking at the test file, there are more than 12 subtest blocks (or could be counted differently). The PR body could be more precise about counting.
