Patterns

PatternWhat it meansWhy it helps
Champion/challengerCompare a candidate with the current best artifact.Keeps improvement grounded.
Specialist populationMaintain narrow high-value models.Reduces waste and improves fit.
Local-first inferenceRun capable tasks on controlled hardware.Preserves private work and reduces latency.
Evidence packetBundle scorecard, lineage, and release notes.Makes adoption explainable.
Lineage DAGParent-child graph for artifacts.Turns experiments into memory.
Resource ledgerTracks latency, memory, energy, and cost.Keeps the ecology frugal.
Human review loopNames where people shape outcomes.Converts expertise into durable capability.
No-op decisionKeep current state when change does not add value.Preserves quality and focus.
Reversible releaseUse shadow, canary, limited release, and rollback.Encourages experimentation with evidence.
Mutualist scoreMeasure whether the ecology strengthens people.Keeps benefits at the center.
