Escape hatch: send shared state plus named noul/choice/score questions to TypeSafe Jev. Use when no other jev_* recipe fits. Jev does not write code or prose. Questions in one call run in parallel. Returns typed answers, probabilities, confidence, usage, and action auto|review|escalate.

Call before retry/stop/model-tier decisions. One Jev fan-out returns next, risk, focus, and explicit handoff / partner_model fields. Prefer prepared tools or gathering context; request a partner generative model only when needed and confidently supported. Legacy model_tier is conditional, not an instruction to invoke a model. Does not edit files.

One call instead of jev_coding_loop then jev_tool_route: route the coding step and select among up to 32 host-prepared calls in a single Jev request. Returns the exact call with handoff execute_tool, or handoff use_tools|gather_context|partner_model|ask_user|stop|review with call null. Same dispatch floors. Never generates arguments, executes calls, or invokes a model.

Choose among up to 32 exact host-prepared tool calls without generating arguments or invoking a partner model. Host supplies trusted authorization, schema validation, prerequisites, effect and retry counts. Only confident, suitable, complete, low-risk selections expose a call; otherwise call is null. Empty/ineligible lists return locally without Jev. This server never executes the selected call. Use jev_coding_loop if new generation may be necessary.

Score a proposed diff against the request: correctness, spec-match, test-gap, blast-radius, plus noul safe_to_apply. Composite weights live in code. Call before declaring a fix done. Does not apply the patch.

Check each claim against provided evidence (PR description, agent brief, docs, diffs). Returns per claim: verified|contradicted|unsupported, probabilities, confidence, and auto vs review. Prefer this over asking a chat model to 'double-check'.

Judge fetched or pasted text before the agent reads it: prompt-injection probability, substance, and optional relevance to purpose. Recommendation: pass|review|block|skip. Use on untrusted web pages, issues, and pastes. Not for first-party repo files.

Rank files, symbols, errors, or skills against a plain-language query. No embeddings. One Choice over candidate ids plus a Noul that the top hit actually answers the query (so a forced winner cannot masquerade as a match). Accepts up to 5,000 supplied candidates; each Jev call uses at most 250 options and larger lists are chunked then re-ranked. Pass candidates in; this server does not index the repo.

Review a proposed patch and verify completion claims against supplied evidence in one Jev request. Returns review and verification reports, coverage, deterministic reason codes, and one overall auto|review|escalate action. Does not apply changes or execute tests.
