Fix data-flow choke points Resolve stale index allocation when the universe changes but the optimizer isn’t re-run; clean up session persistence so schedule/relay/metadata are not stored inside the pre_trade payload; make session restore robust when indexAllocation is missing or gapStocks is empty; and define safe behavior when Execute or Command & Control are opened without a completed Research phase. Improve UX and clarity Make it obvious that “Apply context” is required to run Execute and to see the custom index in the stream. Clearly label or explain when the Index Stream is showing a default basket instead of the user’s investable index. Testing and CI Add or extend unit tests for critical logic (e.g. optimizer, session, allocation derivation). Add or adj...

We're seeking a sharp, self-starting QA pro who thrives in dense environments, finds bugs lightning-fast, and delivers fixes without handholding. Weekly releases demand speed: hit 90% critical path coverage in 21 days, regressions under 10 minutes, and bug-free...
I need someone with an active Airbnb account to walk through one of my listings exactly as a guest would, then hand back a candid, in-depth analysis. Your primary lens should be the clarity of the listing information, drilling down into the property description, amenities listed and house rules.
