Constant Summary collapse

DEFAULT_SWEEP_BUDGET = 
5
MAX_NUDGES =

First-week ROI nudge. Computes per-session metrics (facts contributed via Stop-hook ingest, percentage of those Claude actually used in recall/context-injection) and decides whether to print to the user. Quiets after MAX_NUDGES successful runs or when CLAUDE_MEMORY_NO_NUDGE=1.

The “first ~10 sessions” gate is enforced by counting prior ‘roi_nudge` activity events with status=success across both stores. Once the user has seen the nudge enough times, memory gets out of the way; trust is established or it isn’t.

#refresh_recall_timestamps ⇒ Object

Sweep-derived staleness data. Skips silently if the sweep was given a store-only handler (no manager); the cross-DB refresher requires the manager because project events can touch global facts and vice versa.
