Add Derivation AI
Wire up a Folio kind: ai derivation — the YAML file under derivations/, the prompt template (or promptref), output: text vs output: json with outputschema, and a one-row materialize smoke. Invoke when the user asks to "have an LLM fill a column", "auto-classify", "summarize each row", or anything that maps a free-text field to a structured value via Claude/OpenAI/etc.
Add Derivation Cross Sheet
Wire up a Folio kind: crosssheet derivation — pull a field from a sibling Folio sheet that shares the same primary key (the 1:1 sidecar pattern). Invoke when the user wants to "join two sheets", "pull revenue from the finance sheet into customers", or otherwise copy values keyed by PK from one sheet to another.
Debug Failed Materialize
Diagnose per-cell failures from folio materialize — read the §10.6 envelope, locate the bad cell in provenance.jsonl, narrow with a positional target + --ids, and re-run with --force. Invoke when the user reports "materialize is failing", "this column came back null", "AI calls timing out", or pastes a non-empty failures[] list from the envelope.
Folio Quickstart
Bootstrap a new Folio sheet from scratch — the contract.yaml schema, records.jsonl format, and the first materialize loop. Invoke when the user wants to start a Folio sheet, asks "how do I create a Folio data set", or has only data and needs a typed Folio container for it.
