MOAD-0001 (CWE-407): filterMetrics() in allocate.go calls containsPeer()
(linear scan) three times per metric in our inner loop — once for blacklist,
once for currentAllocs, once for priorityList. With M metrics and B+C+P
total peer-list entries, each allocation decision costs O(M*(B+C+P)).
Fix: Build map[peer.ID]struct{} sets before our loop. Each lookup becomes O(1).
At scale (200 peers, 100-entry lists): ~60x fewer comparisons.
MOAD-0002 (intertangle): allocation state passed as function args, no globals. CLEAN.
MOAD-0003 (leaked context): no ThreadLocal or goroutine-scoped carriers. CLEAN.
MOAD-0004 (logged secret): peer IDs logged, no auth tokens or private keys. CLEAN.
MOAD-0005 (thundering herd): allocation runs under consensus lock. CLEAN.
