When a tool call succeeds, Claude Code records usage data about it, and that record now includes an ID for the call. The ID is hashed, meaning it is scrambled into a form that cannot be read back.\n\nThe part of Claude Code that wrote the note to Claude about tool calls lost when a cloud session restarted has been removed. The settings that control waking a cloud session after a restart still fall back to on.\n\n**Why**\n\nWith the call ID, records about the same tool call can be matched up with each other.\n\n- Flag `tengu_ccr_orphan_restore_wake`: Not enough to say (read for one account on one subscription tier against v2.1.302; this account: no value returned, anonymous baseline: no value returned, compiled default: on) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Flag `tengu_ccr_orphan_restore_wake_shells`: Not enough to say (read for one account on one subscription tier against v2.1.302; this account: no value returned, anonymous baseline: no value returned, compiled default: on) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: Telemetry\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
