/**
 * PRI-482 Phase 3 — Production RuleContext v2 assembler
 *
 * Converts raw TrajectoryDatabase rows into a validated RuleHistoryWindow,
 * and provides buildProductionRuleContext for gate integration.
 *
 * ERR prevention:
 *   - ERR-001: every row field is validated as unknown. No `as` bypass on
 *     parsed params_json or outcome.
 *   - ERR-024: buildProductionRuleContext fail-soft — query failure returns
 *     unavailable, never throws.
 *   - ERR-025: callers use recordToolCall → getRuleHostContextRows → this
 *     assembler, covering the full production chain.
 *
 * Spec: docs/superpowers/specs/2026-06-27-rulecode-context-vision-design.md §5.
