 ### Claude Code facts
 
-Agent SDK 0.3.237 supplies structured error subtypes, but the Claude Code Provider exposes only the action categories owned by the [minimal-diagnostics decision](../simplification/2026-08-21-product-subagent-minimal-diagnostics.md): limits use `limit`, general execution failures use `product-error`, error-marked, blank, or missing results use `invalid-result`, an early CLI exit uses `process`, and unrecognized values or exceptions use `unknown` without copying the value.
-
-| Stage | Owned operation | Observable failure |
-| --- | --- | --- |
-| `query-start` | SDK query construction, native platform-payload startup, and unpublished rollback | `start()` rejects with fixed safe facts and any process outcome observed before rollback |
-| `query-run` | Published SDK message iteration and strict terminal-result validation | The run resolves as `error` with `limit`, `product-error`, `invalid-result`, or `unknown` |
-| `process` | Managed CLI exits before the SDK supplies a terminal result | The run resolves as `error` with `process` and the available exit code and signal |
-| `teardown` | Query close and managed process-tree release | `dispose()` rejects independently with fixed safe facts after cleanup still reaches its final exit wait |
+The [minimal-diagnostics decision](../simplification/2026-08-21-product-subagent-minimal-diagnostics.md) exclusively owns Claude Code categories, stages, process facts, permission ordering, and verification for Agent SDK 0.3.237 and Claude Code 2.1.237. This note carries no separate Claude category contract.

 ## Consequences
 
-The parent can distinguish coarse Claude Code limits, product failures, invalid results, process exits, and unknown failures while Codex still distinguishes its current budget, usage, service, policy, request, connection, stream, rollback, sandbox, and active-turn categories. Neither receives raw product text, and foreground and background scheduling preserve the same fact because both consume one `SubagentResult`.
+The parent can distinguish the current Codex budget, usage, service, policy, request, connection, stream, rollback, sandbox, and active-turn categories without receiving raw product text. The [minimal-diagnostics decision](../simplification/2026-08-21-product-subagent-minimal-diagnostics.md) owns the corresponding Claude result. Foreground and background scheduling preserve the same fact because both consume one `SubagentResult`.
 
 The diagnostic is display text rather than a new public protocol. Callers may present it but must not branch on its punctuation or product-private category names. A pinned product-version upgrade revalidates the Provider mapping and evidence without requiring every official error member to remain model-visible.

 ### Claude Code 事实
