/**
 * SqliteIntentDecisionStore — SQLite implementation of IntentDecisionStore.
 *
 * PRI-470 / SPEC §21.7 durable persistence for Owner decisions on
 * intentTension. Records are written to the `intent_decisions` table
 * (schema created by SqliteConnection.initSchema).
 *
 * Idempotency (SPEC §21.7 req 4):
 * - When `painId` is non-null: dedupe on (pain_id, intent_doc_hash, owner_action).
 * - When `painId` is null: dedupe on (task_id, intent_doc_hash, owner_action)
 *   using the NULL-safe `IS` operator so a null intentDocHash compares equal.
 *
 * Snapshots (SPEC §21.7 audit boundary):
 * - source / evidenceStrength / relatedIntentFields / evidenceRefs are stored
 *   twice: once in the live columns and once in the `_snapshot` columns. The
 *   snapshot is the immutable audit copy; the live columns mirror it at write
 *   time. This keeps the audit trail accurate even if a future migration or
 *   artifact change alters the live columns.
 *
 * ERR checklist:
 * - EP-01 / ERR-001, ERR-005: DB rows treated as unknown, mapped via guards
 * - EP-03 / ERR-002: write failures throw (fail loud)
 * - EP-07 / ERR-015, ERR-018: idempotency SELECT reads fresh state each call
