Triage manual S3 E2E failure and isolate repository mismatch blocker

[Copilot]

The reported failure is a Playwright S3 E2E regression (external-data-advanced.spec.ts, @s3) where advanced-mode UI never becomes visible. In this repository (libamtrack/pyamtrack), those test assets and runtime paths do not exist, so the issue cannot be fixed here without the correct target codebase.

• Issue scope validated

  • Confirmed this repo is Python/CMake (pyproject.toml, pytest) and does not contain the failing Playwright suite, pnpm scripts, or dedx_web paths referenced in the error.
  • Verified the failing CI context for this repo is unrelated (Python particle tests), not S3 E2E UI flows.

• Actionable blocker captured

  • Identified that the requested fix requires the repository/branch containing:
    • tests/e2e/external-data-advanced.spec.ts
    • Playwright config and test:e2e:s3 script
    • /calculator?...mode=advanced frontend codepath

• AI work logs added

  • Added a concise AI investigation log in the task updates with findings and required next input (correct repo/branch).
