Function: driftLeaderProfile()

driftLeaderProfile(profile, model, ctx): TraitProfile

Defined in: apps/paracosm/src/engine/trait-models/drift.ts:145

Drift a leader's TraitProfile in place after a turn outcome, mirroring the semantics of the legacy driftCommanderHexaco in src/engine/core/progression.ts but generic over trait models:

  1. Per-axis pull from model.drift.outcomes[axis][outcome] (defaulting to 0 when missing).
  2. Pull is clamped to ±PER_TURN_DRIFT_CAP (±0.05) BEFORE applying timeDelta scaling. Matches progression.ts:142.
  3. Result clamped to [KERNEL_TRAIT_LOWER, KERNEL_TRAIT_UPPER] ([0.05, 0.95]). Matches progression.ts:143.
  4. The new traits are pushed to the snapshot history.

For HEXACO leaders this produces byte-identical output to driftCommanderHexaco because hexacoModel.drift.outcomes mirrors the canonical outcomePullForTrait table (see hexaco.ts comments).

For non-HEXACO leaders (ai-agent etc), this is the canonical drift call site. Throws when profile.modelId mismatches model.id.
