omo's ultimate-browsing engine added a 'surrogate retrieval tier' (PR #6662):
when a page fetch is blocked by a WAF/paywall/rate-limit, it falls back to
third-party copies (Wayback, archive.today, Jina Reader) with strict
provenance labeling and validators that reject fake successes (dead Google
Cache interstitials, AMP redirect stubs, rate-limit bodies).
Hermes adaptation: a bundled research skill + stdlib-only script instead of
a Python sub-engine — zero core-tool footprint, per the footprint ladder.
Clean-room implementation (their repo is Sustainable Use License; nothing
copied), keeping the good ideas: provenance contract (snapshot vs live),
body validation over status codes, domain rotation for archive.today,
API-first pivot guidance, and explicit skip of proxy relays (MITM).
E2E tested: recovered a real 486KB Wayback snapshot with timestamp;
validators reject redirect stubs, interstitial titles, and sub-floor bodies.
