V2.4.6:
- expands beyond the old 31-channel pool
- same channel can keep up to 6 candidates
- checks multiple candidates before declaring failure
- best currently working candidate is selected
- automatic failover can switch source URLs
- preserves HTTP referrer and user-agent options
- information/donation rows are filtered out
- VERIFIED and SUSPECT stay published
- only 3 consecutive all-candidate HARD failures remove a channel
- persistent health memory in Cloudflare KV
- up to 100 output channels
- no global crawling
- no login/DRM/token/paywall bypass

Principle:
Multiple upstreams discover. Candidate competition decides the route.
