"instructions": "Lexiara serves authoritative legislation text with provenance. Every provision payload carries an `authoritative` flag and a `provenance` block (source URL, retrieval date, licence, content hash); cite the source URL, and treat `authoritative: false` text as a reading aid, never as the operative law. Derived data (transposition links, concept tags) carries method and confidence — anything not method='human' is a lead to verify. Works are identified by ELI URIs, provisions by eIds such as 'sec_4' (UK section 4), 'art_2__para_1' (article 2(1)), or 'sch_8__part_ii__grp_1__para_1' (UK Schedule 8 Part II Group 1 item 1). When a lookup returns a `coverage` block with `requestable: true`, the law is missing from THIS corpus rather than nonexistent: use request_ingestion with the `request_hint`, then poll get_ingestion_request and repeat the original lookup with the handles get_ingestion_result returns. Never fill a gap by inventing text. request_ingestion is the one write in this catalogue: an OAuth connection granted only `read` cannot call it; the caller must reconnect and approve the explicit `ingestion:request` consent. Existing read grants remain read-only.",

Ask this when a term is defined differently in different instruments ('producer' under WEEE, the Batteries Regulation and the PPWR) and the answer depends on which. Each instrument carries `pivotWhy`: why the term matters in THAT act ('carries 38 duties · 6 other definitions build on it').\n\nMeanings are separated on facts only: identical words are grouped, different words are listed apart, and a borrowing is attached to what the borrowing act names.

"description": "When a lookup returns `coverage` with `requestable: true`, ask for the missing instrument instead of stopping or guessing. Give the CELEX (or an EU ELI), the language and the version point; say WHY in one or two sentences; state any testable expectations. Lexiara validates the target, fetches the publisher's own bytes, reads them through the same parser and the same fail-closed checks every other act goes through, and returns handles you repeat your original lookup with.\n\nWHAT THIS TOOL IS NOT. It never fetches a URL you supply — the target must resolve to a publisher identifier this service derives itself, and `proposed_sources` is recorded as a note for a human and is never dereferenced. It states nothing about what the law means: acquiring an act makes the publisher's text addressable and does nothing else.\n\nEXPECTATIONS ARE HYPOTHESES, NOT INSTRUCTIONS. `has_article`, `has_annex`, `mentions` (three words or more), `min_provisions`, `language_is` are checked against the stored rows after publication and reported as matched, contradicted or not_verifiable. A contradicted expectation is reported and the publisher's text is left exactly as published — nothing is invented, translated or back-dated to satisfy one.\n\nIdentical targets from different callers JOIN one acquisition; your rationale stays private to your account. Re-send the same `idempotency_key` to get the same request back rather than a second one. Jobs are asynchronous: read `retry_after`, then poll get_ingestion_request. This tool creates a request: an OAuth grant with only `read` cannot call it; reconnect and approve the explicit `ingestion:request` consent. Existing read grants remain read-only.",
