Token-budget initial context carries thread and context-window lineage that the model should treat as one structured context-window block. Wrapping it in `<context_window>` makes that boundary explicit while preserving the existing window id content. Before this change, the window identifiers were injected as an untagged developer text fragment: ```text Thread id <THREAD_ID>. First context window id: <FIRST_WINDOW_ID> Current context window id: <WINDOW_ID> Previous context window id: <PREVIOUS_WINDOW_ID> ``` After this change, the same payload is wrapped as a context-window block: ```text <context_window> Thread id: <THREAD_ID> First context window id: <FIRST_WINDOW_ID> Current context window id: <WINDOW_ID> Previous context window id: <PREVIOUS_WINDOW_ID> </context_window> ``` This adds shared `CONTEXT_WINDOW_*_TAG` protocol constants, updates `TokenBudgetContext` to render with those markers, treats the new wrapper as contextual developer content when mapping history, and refreshes the token-budget request-shape assertions and snapshot. Verification: - `just test -p codex-core token_budget` - `just test -p codex-core recognizes_context_window_as_contextual_developer_content`
