- Tavily plugin deleted (plugins/web/tavily), keyless endpoints and ring entry removed from keyless_mcp, legacy backend set / credential ladder / preference walks / rescue key map scrubbed. - TAVILY_API_KEY deregistered across config, setup, status, dump, and nous_subscription surfaces. The tvly- redaction pattern stays -- legacy keys in user envs still deserve masking. - Sibling test pins migrated (keenable/exa stand in where tavily was the fixture vendor); tavily test suite deleted. - Docs updated: web-search, configuration, integrations, environment-variables, tools-reference, web-dashboard, provider plugin dev guide. Live-verified from an isolated HERMES_HOME with all web creds blanked: zero-config resolution lands in the 4-vendor ring, live keyless ring search succeeds, no tavily anywhere in resolution order.
