Audit after "did you update tooling for those findings" found three gaps
beyond the four committed fixes:
- R21: docs/SETUP.md had no record of any of it. Adds the "four flow traps"
table — each trap, its measured cost, and where it is now caught.
- family_sweep --only had no coverage assertion, so the 3-vs-50 mis-scope
could recur silently. It now resolves member addrs to their family, always
prints the coverage line, and refuses when it resolves to zero families.
- pregate_check modelled the banking driver's typedef strip but never checked
the consequence. Adds [DROP-RISK] §203 USE-BEFORE-TYPEDEF. R39 NC: flags
the known-bad splice, 0 false positives on the post-hoist file and all 7
other wave-Z TUs (first draft read a typedef named in its own comment).
Also corrects §203 and the phase log: the text that banked was the RENAMED
variant, because gate_stage's backlog.save_draft() overwrote the original on
the failed attempt. Bytes are correct (R22 213/213); the claim "draft
byte-unchanged" was not.
