Operating margin replay infrastructure failure

Operating margin replay infrastructure failure is one of 45 measurements this engine publishes in full. It is regenerated from a real run rather than transcribed, and it is shown here with its own claim boundary so the number and its limits arrive together.

Failure

Exception message
no universe members overlap the window [946684800000, 1780272000000)
Exception type

Stage

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.

Check it yourself

Every figure above is read from /glassbox/operating_margin_replay_infrastructure_failure.json, the artifact the engine wrote. Nothing on this page is typed by hand: the page is generated from that file, so a figure that moves in the artifact moves here and a figure that is not in the artifact cannot appear here at all.
