checkDataStaleAndDefense mixed the question (are these feeds trustworthy?) with
the answer (probe over REST, cancel everything, start polling), inside a 2063-line
class, so the rule could only be exercised through a live adapter.
Separate Query from Modifier: maker-points-defense.ts takes feed ages and health
flags and returns a verdict; the engine keeps every action. Follows the existing
maker-points-logic.ts / grid-logic.ts convention.
Three other enterDefenseMode call sites each spelled out the same 14-field stale
info, 11 fields of which were false/0/null padding. defenseReasonsFor() states
only the known cause.
16 new unit tests cover what previously had none — the age-0 startup case, the
threshold boundary, and the probe-then-defend sequence for a quiet account feed.
250 pass; tsc and oxlint clean. Engine 2063 -> 1939 lines.
