Early sidecar fetch on resume is gated behind tengu_hover_rest, off by default.
What
When resuming a session, the file holding pre-compaction state can now be fetched while the session is being resolved rather than when it is needed, removing a wait during rehydration. Gated off by default behind tengu_hover_rest.
Details
Reads precompact.json from the storage backend, falling back to disk, with an 8 MB size cap; results are held in a cache of at most 8 sessions.
Rehydration uses the pre-read copy when present instead of reading again.
Forked sessions skip the read-ahead.
Evidence
precompact.json
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.
