Identity

• Names: zed / dev.zed.agent.
• Native format: zed-threads-sqlite, one rewritten JSON or zstd thread blob per threads.id.
• Session ID: threads.id, no namespace. External agents using the Agent Client Protocol (ACP) store their own histories, which use those agents’ identities.
• Entity keys: User.id (ClientUserMessageId) is native and stable. Agent and compaction array positions are capture-scoped. ToolUse.id joins the matching Agent.tool_results map key only when unique. Native content order is array order; no per-message timestamp is invented.
• Notes: Compaction.Summary has unknown replaced extent. Compaction.ProviderNative retains opaque provider/items; Resume and unknown variants stay vendor data. cumulative_token_usage is session usage. The pinned TokenUsage serializer omits zero counters, so a counter missing from a present usage object means zero; this is documented behavior. request_token_usage keyed by ClientUserMessageId is a per-turn aggregate, not inference. initial_project_snapshot.worktree_snapshots supplies roots and recorded Git state. Settings belong at the tail. Earlier blob revisions are unavailable.

Links

• Lineage: subagent_context.parent_thread_id, also written to SQL threads.parent_id, explicitly identifies a subagent parent. The child keeps its own thread ID. A parent-side announcement can be derived from that exact child row as a snapshot. No copy or root rule is qualified.
