You verify CODEOWNERS coverage by testing the effective review path for every critical file, not by assuming the file is “covered” because a pattern looks right.
When does virtualizing a long list break keyboard navigation and browser Find?
Virtualization helps rendering cost, but it breaks expected navigation when users need browser Find, stable focus, or document-style reading across off-screen rows.
How do we distinguish false sharing from lock contention or NUMA traffic?
Differentiate false sharing from lock contention, scheduler migration, and NUMA effects using lock evidence, pinned vs. unpinned runs, and original vs. padded layouts.
OIDC logout across applications: what actually terminates
Choose explicit semantics for local cookies, identity-provider sessions, front-channel notifications, and back-channel logout.

No. Keep customer records independent from login identities, and create identities only when someone deliberately needs authenticated access.
Can a customer-hosted agent safely use a client secret shipped in your application?
A client secret shipped in customer-controlled software is not confidential. Design OAuth client authentication around the deployment trust boundary.
Stop retry storms with an end-to-end retry budget
Allocate deadlines and attempts across clients, gateways, meshes, and services so failures do not multiply load.
