SPEC now states that a source which could not be reached must never be
reported as a book that does not exist: Found / NotFound / Unavailable,
where NotFound requires every source to have answered authoritatively.
Also records that a rejected barcode must not be silent, and that the
by-ISBN cover URL is not evidence a cover exists.
run-task.sh exports CLAUDE_CODE_PRINT_BG_WAIT_CEILING_MS=0, per the wave-4
post-mortem: `claude -p` otherwise kills background tasks at 600s, so a
worker that backgrounds a Gradle build can never report on it. Safe to
edit now — no workers are running (hazard: never edit it while they are).
