Summary
Root cause
Older project drafts can contain a model and effort but no
contextSize. Draft initialization and the broad pre-hydration local-edit guard could make the temporary capability default authoritative before the saved provider preset arrived. Context selection belongs to each Codex thread, so it must not be added to the shared app-server pool key.Impact
Fresh Codex chat threads now launch with the context window shown in the composer without requiring the user to reopen the selector. Existing threads retain the context window established when they were created.
