fix: support browser operation IDs on insecure HTTP origins - #85
Conversation
Summary by CodeRabbit
WalkthroughThe change adds an explicit empty-team state and localized messages for operators without available teams. It adds resilient browser and control-client ID generators with Web Crypto and non-Web-Crypto fallback paths. Workbench identity generation now uses the shared helper. Host tests cover trusted forwarded HTTPS requests and remove obsolete untrusted-host expectations. New tests cover all ID-generation paths and global cleanup. Sequence Diagram(s)sequenceDiagram

Merge Risk: 🟡 Moderate · up to This change restricts COOP based on request origin, but current tests do not verify that untrusted or malformed hosts are denied. Incorrect handling could apply isolation headers to unintended HTTP origins, so restore negative coverage before merging. 🚥 Pre-merge checks | ✅ 4✅ Passed checks (4 passed)

Keep negative assertions for the origin gate.
createServerApp sets cross-origin-opener-policy: same-origin in common response middleware for every response. This assertion can pass even when x-forwarded-proto or Host validation is ignored. Restore at least one untrusted and one malformed Host case, and assert that the header is absent.

Problem
On insecure HTTP origins,
crypto.randomUUID()is unavailable. Creating a hosted Flow or generating Workbench operation identities could throw before the request was sent. An enabled Connector with no available Teams also left Flow creation disabled without explaining why.Changes
randomUUID()when available, thengetRandomValues(), with a final fallback when Web Crypto is absent.Cross-Origin-Opener-Policy: same-origin, including when HTTPS terminates at a proxy and the backend receives HTTP. Add a regression test for that deployment path. Plain HTTP browsers may still warn that they ignore COOP.Flow resource IDs continue to be generated by the Server; this change concerns browser operation and idempotency keys.
Validation
Using Bun 1.4.0:
bun run formatbun run checkbun run test— 1,100 tests passed across all three workspaces.bun run buildbun run test:package— public npm package, Browser exports, React 18/19 consumers, Command Artifact and CLI smoke tests passed.No browser automation was used.
