Replace the accept-anything recommendations.items ({type: object}) with a strict
per-item contract (required [rank, candidate, action, why] + typed wsjf) and a
maxItems:7 hint. Strict item structure is what lets the T03 boundary parser
validate each recommendation independently and quarantine only malformed ones.
maxItems is a producer hint (prompt + llm-connect json_schema + T03 mitigation),
NOT a hard reject — a hard maxItems reject would discard a whole 16-item report,
the blast-radius bug WP-0016 removes. DEPLOY COUPLING: the strict schema is also
consumed by the current whole-doc validator, so it must ship with T03's per-item
quarantine parser; until then it increases whole-doc hard-fails. Prompt + max_tokens
headroom + NDJSON framing are documented as a runtime-bundle handoff.
Updated four tests to the strict contract; the forwarded-schema test now reads the
live schema file instead of hard-coding it. Full suite: 213 passed, 1 skipped.
