only historical docs or this plan may remain.\n\n## Test Plan\n\n- Run `cargo build -p fabro-api` after OpenAPI/Rust type changes.\n- Run targeted Rust tests:\n - `cargo nextest run -p fabro-agent`\n - `cargo nextest run -p fabro-workflow`\n - `cargo nextest run -p fabro-store`\n - `cargo nextest run -p fabro-server get_run_stage_context_window`\n - `cargo nextest run -p fabro-types agent_message`\n- Regenerate TypeScript client with `cd lib/packages/fabro-api-client && bun run generate`.\n- Run web checks:\n - `cd apps/fabro-web && bun test`\n - `cd apps/fabro-web && bun run typecheck`\n - `cd lib/packages/fabro-api-client && bun run typecheck`\n- Run final targeted searches:\n - `rg -n \"agent\\\\.context_window\\\\.snapshot|AgentContextWindowSnapshot|ContextWindowSnapshot\" lib/crates apps/fabro-web lib/packages docs/public/api-reference/fabro-api.yaml`\n - Expected: no implementation/API/frontend matches.\n\n## Acceptance Criteria\n\n- Normal agent runs do not emit `agent.context_window.snapshot`.\n- Normal agent runs do not call provider token-count endpoints for context-window reporting.\n- `agent.message` includes context-window data when the agent produced a response.\n- `GET /runs/{id}/stages/{stageId}/context-window` still returns the latest context-window projection.\n- The event log contains no standalone context-window snapshot events.\n- Public API/client/types no longer expose `agent.context_window.snapshot`.\n", + "internal.retry_count.start": 0, "internal.run_id": "01KSDGB3G5YAPQMCXKE23SF08C", + "internal.thread_id": "preflight_compile", + "graph.model_stylesheet": "\n * { model: claude-opus-4-7;
