@leumas/behavior

Interest profiles, rollups and session transitions over the behaviour ledger.

• profile.js — an exponential moving average with lazy decay. The mass decays alongside the

vector, which is what stops the profile freezing; learningRate() is the number that proves it.

• weights.js — event weights in one place. Prose points here rather than restating them.
• rollup.js — pure aggregation: hour/day rollup cells, session-bounded transitions, per-user folds.
• store.js / runner.js — persistence and the job. Drizzle handles are injected.

Nothing here imports a database driver. pnpm --filter @leumas/behavior test.
