/**
 * ollama_change_brief — FLAGSHIP compound job.
 *
 * Produces a STRUCTURED IMPACT BRIEF for a change: what changed, why
 * it matters, what it could break, what should be checked, and what
 * release-note / handoff language is worth drafting. Not a git chat
 * bot and not prose paragraphs.
 *
 * Accepts diff_text and/or source_paths (changed files), with an
 * optional corpus for doctrine/architecture background. No VCS
 * integration — the caller hands in the evidence; the tool
 * synthesizes.
 *
 * Tier: Deep. Evidence-backed, thin-evidence-honest, no remediation
 * drift. likely_breakpoints is investigative ("this could break X");
 * validation_checks are verifications, not fixes. release_note_draft
 * is a draft — operator still reviews.
