- ingest.parse_web: direct fetch; on block/timeout retry via socks5h://127.0.0.1:1080 (SOCKS_FALLBACK_PROXY); raises ValueError if both fail.
- config: add SOCKS_FALLBACK_PROXY default (socks5h://127.0.0.1:1080).
- self_improve.stale_guard: supported LLM verdict now sets status_change='supported' (authoritative), no fallthrough to age fallback -> no double-checked/skipped_no_source.
- README: document auto-fallback.
