Summary

• Simplify Build/Plan instructions, clarify material ambiguities, and remove silence-as-approval and suggestion quotas.
• Share language preference text across system/context, and align shell, compaction, child reporting, and spawn documentation with the Native runtime.
• Derive child prompt identity from actual session ancestry for queries and prompt reads, including restart, nested agents, slash-containing names, and inherited history. Ordinary forks remain root agents. Identity reads do not load actors or schedule recovery.
• Deliver Desktop automation run guidance through supported Native user input instead of the discarded system argument. Read previous-run memory as untrusted tool data under existing permissions, and choose output language from the configured task.
• Keep legacy TypeScript exports for compatibility and document prompt ownership.

Validation

• Rustfmt and git diff checks passed.
• Final focused Rust core tests: 18 passed (RLM prompt contracts, mode contracts, session context).
• Final server integration: 2 passed, capturing actual provider requests and prompt-read responses for root/fork, child/grandchild, inherited history, slash-containing nicknames, and restart/resume.
• Final Desktop suite: 926 passed, 1 platform skip, 0 failed, with an isolated writable XDG_CONFIG_HOME. TypeScript checking passed. Includes actual SDK-to-Native queue payload regression and non-English task preservation.
• An earlier full local core run had 579 passes, 22 ignored, and 3 environment-limited failures (workspace-root discovery, missing dill, and nested sandbox process spawn). Full workspace/platform validation is delegated to the PR CI rather than claiming that local run passed.
• Final HEAD cc2d59c6f82324f4f9241a466e0535fda368876c: all 23 CI jobs passed. CI run 42384789678 and Runtime bundles run 42384789691 both completed successfully, including the full Rust workspace, Windows Clippy, TUI mock-provider smoke, Desktop tests/types, and all runtime targets.
• Independent final code review found no merge blocker. No outstanding review threads.

No live-provider A/B quality claims; these are runtime contract and request-path regressions.
