ask_prepareBYO step 1 of 2: run the server-side trust plane for a business question (plan, SQL-verified facts, evidence retrieval, answerability gate, prompt composition) and return the composed prompt plus a single-use prepare_key (a signed handoff token; echo it back VERBATIM and in full, or use the short ask_id alias; in prose always say the ask_id, never the token).
Inferred read-onlyask_resultFetch the published verdict for an ask_prepare session (status: pending, published, or unknown).
Inferred read-onlyask_submit_draftBYO step 2 of 2: verify the draft you wrote for an ask_prepare prompt.
Inferred read-onlydescribe_fact_capabilitiesList safe metadata for the registered fact queries available on the server-pinned dataset: IDs, labels, parameters, and result shapes, never SQL.
Inferred read-onlyfind_payroll_anomaliesSurface payroll and deduction anomalies in the latest snapshot.
Inferred read-onlyget_answer_queriesShow the SQL behind one answer you already received, addressed by its correlation_id.
Inferred read-onlyget_evidence_documentShow ONE retrieved evidence document behind an answer you already received, addressed by that answer's correlation_id plus a document_id from its evidence_documents references.
Inferred read-onlyquery_factExecute a registered, versioned read-only fact query against the server-pinned dataset.
Potential side effectsrun_codeRun YOUR OWN JavaScript in the in-tenant coderunner sandbox with the read-only, snapshot-scoped plumb.
Inferred read-onlyrun_sqlRun YOUR OWN single read-only SELECT/WITH over the virtual snapshot_* relations.
Inferred read-onlysearch_docsSearch Plumbline's own product and architecture documentation (how the verification, refusal, and trust layer itself works).
Inferred read-onlysearch_employeeSearch the employment fact store for a person and return a grounded, verified answer.
Inferred read-onlytrust_finalizeReturn the session's graded trust verdict: the tier (verified / registered-query / generated-sql / corroborated / unverified / conflict / refused), which trusted steps were skipped across the session, the deterministic confidence (k of n figures store-verified, weakest figure tier, conflicts), the per-figure provenance, the per-call ledger, and the at-your-own-risk disclaimer.

TRUST AND VERIFICATION EVIDENCE
Loading Trust v2 evidence…
Checking the associated registrable domain. The BuiltWith key remains server-side.
Evidence is source-attributed and does not guarantee that a third-party server is safe. Risk labels are conservative metadata heuristics.
