# v164 — Premium Timeline Refactor

- Reworked the Active Run timeline as a premium, single-row milestone system with clockwise partial rings for grouped substeps.
- Renamed user-facing timeline labels where helpful while retaining worker-step precision underneath.
- Kept Agent recovery and Run traces roles from v158/v159; v120 Agent recovery remains documented and visible as the operational recovery summary.
- Reduced redundant terminal Failure milestone: precise failed stages are marked directly, with Failure only as a fallback terminal anchor.

Validation: 452 tests pass.

# v163 — Section Harmony Audit

- Reviewed the one-page UI section by section for state ownership, event-handler conflicts and cross-panel interference.
- Fixed duplicate DOM IDs in the support/compatibility area so hidden legacy elements no longer shadow visible Active Run hardware fields.
- Separated Space Test's visible “Started at” field from the Active Run polling compatibility field. Active Run progress no longer writes into the Space Test timestamp.
- Hardened Run traces document state so backend-provided `present: true` document links are not downgraded when a light payload lacks a `files` listing.
- Added regression tests covering unique DOM IDs, Active Run vs Space Test timestamp separation, hidden-field compatibility boundaries, and stable Run traces document presence.

Validation: 448 tests pass.
