Addendum v0.9 · Multi-fabric, multi-pipeline SOTA architecture

No single model, optimizer, or pipeline is allowed to run the company.

Multiple independent analytical and decision pipelines run against shared canonical state. Their outputs are reconciled, disagreement is exposed, and the best admissible action is selected or presented. Design / stub — not a live federated runtime.

Canonical Event State → N independent pipelines → parallel solvers → cross-model coherence → Pareto evaluation → policy/human constraints → ranked decision frontier → execution → receipt → settlement → champion/challenger → repeat.

Decision Fabric

The Decision Fabric reconciles candidates instead of letting one pipeline control operations: evidence weighting, cross-pipeline agreement/disagreement, hard-constraint validation, uncertainty, expected-value/risk scoring, ranked action set, then human or authorized autonomous execution. Agreement raises confidence. Strong disagreement is an operational signal — not something to hide inside an average.

Functional fabrics

Real-Time Operations

Seconds/minutes: booking, dispatch, call-ins, emergencies, Van state, rebase, windows.

Planning

Hours/days/weeks: staffing, PTO, maintenance capacity, protected reserve, borrowing.

Economic

Labor × cost × profit, contribution, margin, opportunity cost, pricing, procurement.

Evidence

Receipts, provenance, media, hashes, source conflict, point-in-time truth.

Learning

Training, calibration, historical replay, skill/demand learning, drift.

Simulation

Counterfactual schedules and no-impact synthetic operating runs.

Analytics

Reports, graphs, models, scales, probabilities, human-review queries.

Parallel pipelines

Deterministic RulesHard constraints, safety, qualification, SLA, policy.

Historical AnalogueComparable past calls/days/branches as empirical evidence.

Human-HeuristicRecurring override patterns — without assuming the human is always correct.

Pareto frontier

Do not collapse every material choice into one opaque score. A manager may see a fastest-response plan, highest-contribution plan, lowest-reschedule plan, and best-balanced plan. Trades recommends one; alternatives remain visible and auditable.

Champion / challenger

Challengers stay in Shadow until settlement against actual outcomes. Do not delete the prior champion immediately. Preserve rollback and version lineage. Branch-specific ensembles are versioned; one universal mix is not assumed.

Fault tolerance

Any model, fabric, connector, or optimizer may fail independently. A Simulation or Analytics outage must not stop dispatch. An AI outage must not stop booking. A local branch continues if central analytics is unavailable. Cross-fabric contradictions are surfaced — Operations vs Workforce availability, Economic vs Schedule, Inventory vs stale Evidence — before the Decision Fabric emits an action.
