 ## Checklist
 
-- [x] Clarify scope, repository boundaries, and validation requirements for a repository-level AGENTS.md.
-- [x] Verify that the plan covers the user-specified workflow rules, project structure, and risk points.
-- [x] Create a complete AGENTS.md that embeds the requested workflow orchestration rules and repo-specific guardrails.
-- [x] Verify the generated AGENTS.md against the current repository structure and required workflow sections.
-- [x] Update the Review section with the final result and verification evidence.
+- [x] Confirm the current `store_dwell_alert` half-hour report path and identify the runtime control point.
+- [x] Verify the plan covers behavior change, focused tests, deployment scope, and post-deploy validation.
+- [ ] Update focused tests so `half_hour_report` is expected on rolling 1800-second windows from startup time.
+- [ ] Implement the rolling window behavior in `store_dwell_alert` runtime code.
+- [ ] Run focused `store_dwell_alert` tests for the changed slice.
+- [ ] Deploy the updated `store_dwell_alert` code to `xiaozheng@10.8.0.11` and restart only the affected service(s).
+- [ ] Validate the remote deployment and update the Review section with evidence.
 
 ## Scope And Risks
 
-- Scope: add a repository-root AGENTS.md that governs future modifications across the Go backend, Vue frontend, deployment assets, and embedded Python managed services.
-- Risk: omit a repository area or validation command and leave future work under-constrained.
-- Risk: copy the requested workflow rules without adapting them to this repo's actual layout and toolchain.
-- Risk: finish without writing persistent task evidence for plan, review, and lessons.
+- Scope: change `managed/store_dwell_alert` so `half_hour_report` uses rolling 1800-second windows from service startup instead of natural `:00` / `:30` boundaries, then deploy the change to `10.8.0.11`.
+- Expected touch points: `managed/store_dwell_alert/app/modules/dwell_engine.py`, `managed/store_dwell_alert/app/modules/reporter.py`, and focused tests under `managed/store_dwell_alert/tests/`.
+- Risk: changing the window model can alter `window_start` and `window_end` values consumed by downstream webhook receivers and manage APIs.
+- Risk: a delayed observation call may span more than one 30-minute window; the implementation should behave predictably and avoid duplicate emissions for the same window.
+- Risk: deployment should be limited to `store-dwell-alert` unless code or config diffs prove broader scope is required.
+
+## Validation Intent
+
+- First pin the new expected behavior with focused tests.
+- After the code change, run the narrowest `store_dwell_alert` tests that cover report timing and report payloads.
+- After deployment, verify the remote service is healthy and that the deployed code matches local content.
 
 ## Review
 
-- Status: completed.
-- Result: added a repository-root `AGENTS.md` plus `tasks/todo.md` and `tasks/lessons.md` to enforce the requested workflow for future non-trivial tasks.
-- Verification:
-  - confirmed `AGENTS.md` exists at the repository root;
-  - read back `AGENTS.md` and verified it covers workflow orchestration, task management, repo structure, validation matrix, and definition of done;
-  - matched required repository-specific references including `internal/webdevice/`, `managed/people_flow_project/`, `managed/store_dwell_alert/`, `tasks/todo.md`, and `tasks/lessons.md`.
+- Status: in progress.
+- Result: pending.
+- Verification: pending.
