Persist preferences and working context across sessions.

The sourced Grok Bot cell covers the documented memory of a named Bot. It does not imply perfect recall, a user-visible memory editor, isolation between Bots, or that remembered facts are current.

All other harness cells remain **unknown** until a dated note and public source support a more specific status. Use the Markdown and JSON twins if you are an agent reading this site.

  - Target: hosted-observation — 2026-08-28 Grok Bot desktop documentation observation; observed 2026-08-28
  - Environment: hosted-default
  - Constraint (runtime): stable preferences, facts, and summaries persist with the named Bot; shared files and sign-ins belong to the account-scoped computer
  - Constraint (policy): memory is not an authoritative source and can become stale
  - Evidence: [xAI — Create and manage Grok Bots](https://docs.x.ai/grok-bot/bots) — documented; observed 2026-08-28
  - Qualification note 1: Evidence checked 2026-08-28: xAI documents that a Grok Bot can retain stable working preferences, important facts, and work summaries over time; it warns that memory is not a substitute for an authoritative source.
