Answers the fixture-priority spike with a coverage matrix, threat mapping, and two compared prioritization strategies. Recommends multi-op envelopes, setOptions, manageSellOffer, accountMerge, memo coverage, and malformed-envelope fixtures as the first tranche, since they converge on both strategies and close taxonomy gaps (signer-takeover, memo-impersonation, sponsored-mule) that already have zero fixtures behind them.
