 ## 1. Host Agent local task storage (D1, D2)
 
-- [x] 1.1 Add `HOST_AGENT_TASK_PROGRESS_DB_PATH` (and matching artifact directory config) to `HostAgentConfig`/`load_host_agent_config()`, with a Host-Agent-specific default distinct from any local Runtime `tasks/` path.
+- [x] 1.1 Add `HOST_AGENT_TASK_PROGRESS_DB_PATH` (and matching artifact directory config) to `HostAgentConfig`/`load_host_agent_config()`, with Host-Agent-specific defaults for durable execution history.
 - [x] 1.2 In `HostAgentApplication`'s builder (`app.py:218-223`), construct a `TaskMetadataStore`/`Timeline` from that config and pass them into `create_execution_factories(..., metadata_store=..., timeline=...)`.
 - [x] 1.3 Add delete/prune methods to `storage/task_metadata.py::TaskMetadataStore` and `storage/timeline.py::Timeline` (remove a task's row, timeline records, and screenshot artifacts).
 - [x] 1.4 Implement a bounded retention pass in the Host Agent (default: keep the newer of "last 50 tasks" or "7 days", whichever keeps fewer rows) that runs after each assignment finishes, calling the new prune methods.
-- [x] 1.5 Add unit tests: step transitions persist during execution; a task's history is queryable after the assignment completes and the in-memory `Task` is discarded; retention prunes tasks beyond the configured threshold; Host Agent and a local Runtime process using default paths on the same machine do not collide.
+- [x] 1.5 Add unit tests: step transitions persist during execution; a task's history is queryable after the assignment completes and the in-memory `Task` is discarded; retention prunes tasks beyond the configured threshold; Host Agent task metadata and artifacts use their configured local paths.

 ## 5. Host Agent local console task pages (D3)
 
 - [x] 5.1 Extend `AgentStatusTracker`/`/api/status` (or a small addition alongside it) to surface the current step index/status/summary for the in-progress assignment, sourced from the same progress holder built in section 2, and update the dashboard's "Current assignment" rendering to show it.
-- [x] 5.2 Add authenticated, read-only task list and task detail/timeline routes to `host_agent/web/app.py`, querying the Host-Agent-local `TaskMetadataStore`/`Timeline` (reusing the same query calls `api/console.py` makes) and rendering server-side HTML consistent with the existing dashboard's f-string + `html.escape()` convention, including inlined screenshots on the detail/timeline page.
+- [x] 5.2 Add authenticated, read-only task list and task detail/timeline routes to `host_agent/web/app.py`, querying the Host-Agent-local `TaskMetadataStore`/`Timeline` and rendering server-side Jinja HTML consistent with the existing console, including inlined screenshots on the detail/timeline page.
 - [x] 5.3 Gate the new routes behind the existing Host Agent console session/CSRF protection; verify no new CORS configuration is introduced.
 - [x] 5.4 Add tests: unauthenticated requests to the new routes are rejected the same way as other console routes; task list/detail/timeline pages render expected data including screenshots for a completed task.
 
 ## 6. Documentation and verification
 
 - [x] 6.1 Update `docs/MACOS_IPHONE_SETUP.md` and/or `docs/CLOUD_DEPLOYMENT.md` with the new Host Agent config vars (`HOST_AGENT_TASK_PROGRESS_DB_PATH` and retention settings) and a short note on where to view live/historical task progress in each console.
-- [x] 6.2 Run `uv run --all-packages pytest -m "not integration"` and targeted Cloud API / Host Agent test suites; run `cloud-console/` and `console/`-equivalent Vitest suites for the touched frontend.
+- [x] 6.2 Run `uv run --all-packages pytest -m "not integration"` and targeted Cloud API / Host Agent test suites; run the Cloud Console Vitest suite for its touched frontend.
 - [x] 6.3 Run Ruff check/format and `compileall` across touched packages.
 - [x] 6.4 Run `openspec validate --strict` for this change.
 - [ ] 6.5 Manual verification (requires a real Host Agent + Appium/device setup per `docs/MACOS_IPHONE_SETUP.md`): run a real task end-to-end and confirm step progress appears live in the Host Agent console and Cloud Console, and that full step history with screenshots is browsable afterward in the Host Agent console.

 - [x] 7.1 Extend `ToolCallDecision` (`runtime/tool_calling_client.py:23-27`) with the actual prompt content given to that call (or return it via a small side-channel from `AIPlanner.plan()`, not by changing the `Planner.plan()` return type used by other planners).
 - [x] 7.2 Update `TaskRunner._append_timeline()` (`runtime/task.py:296-319`) to pass the real per-step prompt and the model's resulting decision into `Timeline.append()`, instead of `task.goal`.
 - [x] 7.3 Update `storage/timeline.py`'s `Timeline`/`TimelineRecord` field(s) so the persisted meaning is unambiguously "the prompt actually sent to the LLM for this step" (rename or add a field; keep backward-compatible read of any already-persisted rows if a Runtime dev DB might already have old-shaped rows).
-- [x] 7.4 Update any renderer of this data (`api/console.py`, Runtime `console/`, and the new Host Agent console task pages from section 5) to show the corrected field.
+- [x] 7.4 Update the Host Agent console task pages to show the corrected field without requiring a separate Runtime renderer.
 - [x] 7.5 Add unit tests: a persisted step's prompt matches what `AIPlanner.plan()` actually sent for that step (not the task goal), across at least one multi-step task.

 - [x] 10.2 Capture before and after screenshots around every TaskRunner executor call, then persist the action, result, and available OCR observations in the same timeline record.
-- [x] 10.3 Extend the Runtime console JSON API and task-detail UI to render before/after screenshots, operation details, and available OCR results.

+- [x] 11.1 Make `TaskRunner.run()` create a task metadata row idempotently before status updates; add optional generic source task/attempt fields to task metadata and record Cloud assignment correlation in the Host adapter.
+- [x] 11.2 Add regression coverage for Host-dispatched goal execution, workflow-owned TaskRunner execution, retry-safe metadata creation, and Cloud task/attempt correlation.
+- [x] 11.3 Extend Host Agent `/tasks` and task-detail rendering so the actual execution list and detail page show correlation, before/after screenshots, operation detail, OCR observations, and structured normalized UI-tree results, including legacy screenshot compatibility.
+- [x] 11.4 Remove the standalone Runtime REST service/UI, its package data and dedicated tests, and remove Runtime supervision from Host Agent configuration/supervision with an actionable legacy-config error.
+- [x] 11.5 Update operator documentation and OpenSpec artifacts to direct execution inspection to Host Agent `:8765/tasks` and remove port `8000` instructions.
+- [x] 11.6 Run focused Host Agent and shared Runtime tests, workspace non-integration tests, Ruff, compileall, and strict OpenSpec validation.
+- [ ] 11.7 Manual verification (requires a real Host Agent + Appium/device setup): submit or dispatch a task, then confirm the Host Agent console is the only local execution-history UI and shows the complete retained evidence.
