eval: three detector defects from run 37170610789 (feaa28d)

- safety-codex-consult-embed: the fake codex recorded argv only, but every
  codex exec takes its prompt on stdin since E5; it records stdin for the
  '-' form and the check reads both.
- ship-docsync-missing-asset: 'ls ... 2>&1' on a read-only command is the
  same harmless stderr wrapper as '2>/dev/null'; stdout redirects, pipes
  and script calls stay rejected.
- qa-functional-webhook-fix: a pre-repair capture whose command reran on
  the repaired inputs may be classified superseded (exploratory §4); the
  evidence check accepts that and still rejects superseded on a post-repair
  capture or one never rerun.
Each free regression fails without its repair.
