-summary: Restore trustworthy local Docker validation by fixing the current empty bind-mount/import failure for `./app -> /app/app` under the local OrbStack workflow.
-acceptance_criteria:
-  - `docker compose up -d --build` starts the local stack cleanly.
-  - `docker compose ps` shows the app container healthy instead of restart-looping.
-  - `docker compose run --rm --entrypoint python app -c 'import app.main'` succeeds.
-  - Inside the app container, `/app/app` contains the repository's actual application files.
-  - `/health` and at least one changed route can be validated against the Docker-served app, not only a direct local uvicorn process.

+summary: The event comparison page now explains why one ranked strategy beat another by exposing a selectable drilldown over the ranked results.
+completed_notes:
+  - Added service-backed drilldown models in `app/services/event_comparison_ui.py` for ranked strategy selection, worst-LTV inspection, breach dates, and daily path rows.
+  - Updated `app/pages/event_comparison.py` to render a `Strategy drilldown` selector, selected-strategy summary cards, worst-LTV and breach-date highlights, and a daily path details table.
+  - Added regression coverage in `tests/test_event_comparison_ui.py` and extended `tests/test_e2e_playwright.py` so drilldown selection proves route-visible content changes.
+  - Local Docker validation is now confirmed on Docker Desktop: the stack starts cleanly, `/health` returns OK, and browser automation on the Docker-served `/{workspace_id}/event-comparison` route verified the drilldown UI and selection updates.
+  - The earlier Docker validation confusion was caused by a local SSH port-forward hijacking host requests to `localhost:8000`, not by the app container itself.

-summary: Explain why one ranked strategy beat another on the event comparison page.
-acceptance_criteria:
-  - Selecting a ranked strategy shows daily path details.
-  - UI exposes margin-call days, payoff realized, hedge cost, and final equity.
-  - Worst LTV point and breach dates are highlighted.
-  - Browser test verifies drilldown content updates when selecting a ranked result.
-progress_notes:
-  - The drilldown UI and service models are implemented in `app/pages/event_comparison.py` and `app/services/event_comparison_ui.py`.
-  - Focused unit coverage is green and direct local-browser validation against a fresh local uvicorn process succeeded.
-  - Closure is waiting on the local Docker validation path because `docker compose up -d --build` currently surfaces an environment-specific empty bind-mount/import failure for `./app -> /app/app`.
