eureka-state door: a decode refusal names the field path, never a value
Documents decode one by one through serde_path_to_error, so the refusal says documents[i].path and what is wrong, in the schema's words: a field name, the allowed variants, the expected type. Serde's own text quotes the input, so it is not passed through. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

eureka-state: one text door; the MCP admit decodes through it
The strict decode that refuses unknown keys by path moves from the huginn binary to eureka_state::door; the CLI re-exports it and the MCP admit takes documents as a Value (schema still Vec<PipelineDocument>) and decodes through it, answering InvalidInput before any call. A research note with extra keys is refused by path and nothing is stored. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
