/**
 * @fileoverview Audit-mode resolver for SMI-4587 consumer namespace audit.
 * @module @skillsmith/core/config/audit-mode
 *
 * Pure resolver mapping (tier, override) -> AuditMode for the inventory
 * collision detector. Lives in core (not mcp-server) so the CLI, web
 * surfaces, and MCP server can share one resolution path. Subpath export:
 * `@skillsmith/core/config/audit-mode`.
 *
 * Resolution rules (decision #1 in plan):
 *   1. If `override` is set and is a valid AuditMode, return it.
 *   2. Otherwise return the tier default:
 *      - community / individual -> 'preventative'
 *      - team                   -> 'power_user'
 *      - enterprise             -> 'governance'
 *   3. Unknown tier -> 'preventative' (fail-safe).
 *
 * `'off'` is only reachable via an explicit override. The detector treats
 * 'off' as a short-circuit (returns an empty InventoryAuditResult and
 * skips telemetry).

 *   - 'governance':   same as power_user; reserved for stricter Wave-3 policy
