Session resume can now skip recomputing a conversation summary by reusing one precomputed ahead of time (feature-gated)
What
- A new path lets the agent loop reuse a previously precomputed compaction summary, built ahead of time and cached by session id, model, and boundary, instead of running compaction fresh.
- The cached summary is validated before use: its age, model match, and token growth are checked, with rejection reasons including
session_mismatch,model_mismatch,bad_timestamp,too_old,grew_too_much,shrank_too_much, andpreserve_uuid_missing. A successful reuse emitstengu_precomputed_compact_rehydrated. - The session-resume warning dialog now shows a "Resume from summary (instant, recommended)" label instead of the usual "Resume from summary (recommended)" when a precomputed summary is available (
hasPrecomputedSummary). - The resume flow, gated by
tengu_gleaming_fair_reuse(extendingtengu_gleaming_fair), can skip recomputation entirely, or detect that a precomputed summary has gone stale.
Why Recomputing a full conversation summary on every resume is slow; reusing a precomputed one when it's still valid should make resuming a session noticeably faster. The feature is currently gated off.
