Failure
- Exception message
- no universe members overlap the window [946684800000, 1780272000000)
- Exception type
- ValueError
- Stage
- SignalService._panel universe membership load
- Universe rows visible
- 0
Root cause. UniverseStore.glob does not traverse a top-level symlinked universe_membership dataset directory.
Symlinked datasets
- fundamentals
- ohlcv_1d
- universe_membership
Required next action. Build a new physical lake version with real dataset directories and hard-linked leaves, verify non-empty universe overlap before replay, preserve this failed version, and launch at most one replacement replay.
