"""One-shot LOCAL pipeline for the 'run-halacha' button (halacha validation).

The /api/cases/{case}/final/run-halacha endpoint wakes the Hermes curator, which
runs THIS single deterministic command (the 3-judge panel uses local DeepSeek+Gemini
keys + the local claude CLI, so it can't run inside the container).

Steps:
  [0] precedent_extract_halachot → extract the halachot the DECISION ITSELF states
      (its own case_law row), so they aren't left pending. Idempotent.
  [1] extract_internal_citations(chair) → links the citation graph for the chair's
      decisions (idempotent; ON CONFLICT DO NOTHING).
  [2] corroboration_rebuild → builds the citation-treatment signal and applies the
      corroborated→approved / overruled→pending policy (X11 Phase 2).
  [3] halacha_panel_approve --apply → 3 judges (Opus+DeepSeek+Gemini); agreement
      auto-approves/rejects (reversible, CSV-backed); splits/defects → chair (INV-G10).

NB: per-precedent halacha extraction for newly-cited precedents is NOT automated here
(it needs each cited precedent to be in the library with a known case_law_id) — the
chair drives that from /precedents when a missing precedent is added.

Local-only. Idempotent. The panel pass over the full pending queue can take minutes.
