PathwayMemory

Learned routing memory: problem_class → route → outcome_quality

Definition

Mechanism

A Cache of routing outcomes, recording (problem_class, route_chosen, outcome_quality) tuples. Enables a dispatching Solver to learn which routes produce better results for which problem types. The RootSolver's PathwayMemory is the architecture's most consequential site of compounding — it sees how every problem enters the system, and its accumulated routing decisions determine which reasoning highways densify over time. Every dispatching node has its own PathwayMemory; they are not shared, but can be aggregated for cross-node learning.

Invariants

  1. Append-only within a session: historical records are not edited, only new entries added.
  2. Scoped: each PathwayMemory belongs to exactly one dispatching node.

Risks

Failure modes

  1. Poisoned entries (false outcome_quality from compromised writers) silently bias all downstream routing without triggering any failure mode.

  2. Stale entries reflecting outdated problem distributions mislead current routing; no automatic aging.

  3. Cross-node aggregation without provenance contaminates local routing with off-domain signal.

Caution

Silent contamination vector — poisoned entries bias all downstream routing decisions without triggering failure modes. Integrity of writers must be enforced.
