Record the sandbox modal-open-timeout flake in lessons.md - #19
Merged
Conversation
Reproduced deterministically across three unrelated specs (PrintingTagPicker, TagVotePicker, CardDetailedViewModal.visual) and on unmodified master, isolated from network/mock state - a durable, reusable finding for future sessions hitting the same "Card Details" timeout in this sandbox, so it doesn't get re-diagnosed as a regression each time.

Description
Docs-only follow-up to #15/#17. While verifying #17,
CardDetailedViewModal.visual.spec.tsfailed on a "Card Details" text timeout - traced this to a pre-existing, deterministic (not flaky) Claude Code cloud-sandbox issue, not a regression: reproduces identically acrossPrintingTagPicker.spec.ts,TagVotePicker.spec.ts, and this visual spec, including on unmodifiedmaster, isolated--workers=1runs, and with no relationship to backend/mock state. Recording it indocs/lessons.mdso a future session doesn't re-diagnose the same thing from scratch.Checklist
