📄 Description

Needs https://github.com/better-auth/better-auth/pull/6891 to be merged before it can be reviewed

Summary by cubic

Adds a deferSessionRefresh option to defer session refresh writes to POST so GET is read-only, enabling read‑replica setups. Off by default.

  • New Features
    • Added session.deferSessionRefresh?: boolean to BetterAuthOptions (default false). When enabled, GET is read-only and refresh occurs on POST.
    • /get-session now supports POST (only when deferSessionRefresh is enabled). GET performs no writes, includes needsRefresh (respects disableSessionRefresh), and does not delete expired sessions; deletion/refresh happen on POST. OpenAPI exposes both GET and POST.
    • Client refresh manager detects needsRefresh and posts to /get-session when needed; otherwise no POST.

Written for commit 15827656e5. Summary will update on new commits.

Fixes https://github.com/better-auth/better-auth/issues/6799
