* fix(scanner,data-usage): fix add() logic inversion and usize underflow in reduce_children_of Bug #1: add() had inverted logic — returned early when children were present, making the recursive child traversal dead code. Leaf compaction path was completely non-functional. Fixed by recursing into children when present and collecting leaves only at leaf nodes. Bug #2: reduce_children_of used which underflows in debug (panic) or release (wraps to usize::MAX, compacts entire cache). Fixed with saturating_sub. Both bugs existed identically in crates/scanner and crates/data-usage. Added 5 tests covering add() subtree traversal, edge cases, and reduce_children_of compaction behavior. Closes rustfs/backlog#652 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix: collect internal nodes as compaction candidates, not leaves The previous fix for add() collected leaf nodes (children empty) as compaction candidates. This is incorrect: total_children_rec returns 0 for leaves, so compacting them never decrements — the compaction loop makes no progress. Collect internal nodes (children non-empty) instead. Compacting an internal node removes its subtree via delete_recursive, which actually reduces the total child count. Leaf nodes are skipped since they have no children to remove. Updated tests to match the corrected semantics. * refactor: rename leaves→candidates, add data-usage regression tests - Rename misleading variable/parameter to in add() and reduce_children_of() for both crates - Add 4 regression tests in crates/data-usage covering add() candidate selection and reduce_children_of() compaction + saturating_sub * fix: address data usage compaction review feedback --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com> Co-authored-by: houseme <housemecn@gmail.com>
