A live G0 sourcing run failed on both: a transient connection/decode error aborted
the whole enumeration (the bare except raised http_failure on the first blip), and
the advisory journal stored full raw advisory JSON and reached 1.77 GB on a near-full
host. Fix: the JSON transport now retries URLError/timeout/ConnectionError/IncompleteRead/
JSONDecodeError through the same attempt-4 backoff as HTTP 5xx/429 (fatal only after the
cap or on a genuinely non-retryable error); enumerate_advisories journals only the fields
resolution/extraction consume via source.reduce_advisory (ghsa id, published/withdrawn,
type, CWE ids, package ecosystem/name for OSV, fix-commit links), with journal_version
bumped to 2 so an old full-format journal is rejected and resume-skip stays intact.
Offline: test_unseen_source/draft/extract 133 passed; ruff + format clean; mypy unchanged
(pre-existing verify.py lambda only).
