Hygiene scan (this run)

• Open PRs before this PR: 0
• Stale agent/* branches (>7d, closed PR, no open PR): 3 — issue-10525/10526/10527 (Jun 22); safe to delete remote after merge
• Stale chore/cleanup-* merged branches: jun28-wave9, jun28-wave10 (>7d)
• 48 feat/* branches with no PR and last commit before Jun 23 — left for a dedicated prune (not agent/*)

Verification

• git grep across test/, script/, lib/, docs/: no dangling references to deleted repro stems
• Deletions only; no runtime/compiler logic touched

Test plan

• Reference scan (no dangling require/PHPUnit paths)
• ./script/ci-fast.sh (inventory + spine sync — deletion-only PR)
