main already ships fleetd#164 points 1 and 2 (MIN_TURN_NANOS floor + hard-fail on an
empty/unreadable scrape, commit 3bfa828, already an ancestor of main). The rescued
worker branch worker/cb-164-empty-scrape-false-success-1a80af-3 (851ebca) reimplemented
the same two behaviours via a separate, more invasive mechanism (elapsedNanos threaded
through TurnListener/Injector/Fleetd) that would conflict with main's already-shipped
clock-injection design if merged wholesale.
Port forward only what main is genuinely missing: the narrow BACKEND_ERROR pattern
(`(?i)\bAPI Error\s*:`) that classifies a cleanly-scraped-but-backend-rejected turn as a
failure naming the member, instead of letting the error text resolve as a completed
reply. See REPORT-cb164.md for the full reasoning, what was deliberately not ported, and
the sabotage proof for the new tests.
