Root Cause

The +33 improvement traces directly to the three PRs that landed after eval #15:

• PR fix: thread fixes_count_only through cycle verifiers (#0139) #167 (task security: fix prompt-guard blind spot -- add check_origin_integrity #139): Fixed count-only Claude payload false-rejection. Both cycles now accepted.
• PR fix: pentest guard gaps + eval scorer rejected-cycle fallback #158 (tasks Session index survives git reset — move out of gitignored path #101/Task queue cap: stop generating tasks when 50+ pending #102): Improved rejected-cycle parser fidelity.
• PR review: harden nightshift/evaluation.py and fix 2 pentest findings #165: Hardened evaluation.py and fixed pentest findings.

Test Plan

• make check passes (882 tests, ruff, mypy, dry-runs, ASCII check all green)
• Evaluation ran with no manual overrides (prescribed default command)
• Eval report at .recursive/evaluations/0016.md scores all 10 dimensions with raw evidence
• Task docs: add follow-up tasks #0190 #0191 from PR #176 review #177 marked done with completion date
