The depth parameter controls how many container levels are deep-copied vs shared. Only 2 tests in t/03-scalar.t exercised it (and only for COW string refs at depth=2). New test file covers 36 cases across: - depth=0 (no-op / same SV returned) - depth=1 (shallow clone — inner refs shared) - depth=2 (two-level clone — leaf refs shared) - depth=-1 (default unlimited deep clone) - mixed array/hash nesting - blessed objects at various depths - circular references with depth limits - scalar references (RV traversal doesn't consume depth) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
install-with-cpm@v1 regressed on Perl 5.8-5.22 after a recent cpm update requiring Perl 5.24+. Bump to @v2 for action-based jobs and use direct `cpm install` in the Docker-based Linux matrix (where cpm is pre-installed). Matches the approach approved by @atoomic in PR garu#120.

What
Adds
t/28-depth-parameter.twith 36 tests covering theclone($ref, $depth)API.Why
The depth parameter is a user-facing feature but had almost zero dedicated test
coverage — only 2 assertions in
t/03-scalar.t(COW string refs at depth=2).No tests verified the actual depth-limiting behavior: sharing vs cloning at
each level, interaction with blessed objects, circular refs, or mixed structures.
How
Tests are organized by depth value and structure type:
Testing
All 36 tests pass on macOS system Perl. Full existing test suite unaffected.
