Document Type: Architecture
Status: Active Brain
Version: v1.0
Authority: MWMS HeadOffice
Applies To: SIT Brain system integrity architecture, validation structure, routing verification, schema compliance, and enforcement support across MWMS
Parent: MCR
Last Reviewed: 2026-04-07
Purpose
SIT Brain exists to define the structural integrity layer of MWMS.
Its role is to verify that the system behaves according to declared architecture, routing rules, schema standards, lifecycle requirements, and logging discipline.
SIT Brain protects the ecosystem from hidden drift.
It does not create business strategy.
It does not evaluate offers.
It does not optimise campaigns.
It validates structural correctness.
Scope
This architecture applies to:
• SIT Brain structural role inside MWMS
• validation of task, event, and routing integrity
• schema compliance support
• append-only enforcement support
• cross-brain consistency validation
• workflow integrity testing
• decision logging validation
• signal logging integrity review
• integrity dashboard and violation visibility planning
This page defines the structural role of SIT Brain as an architecture layer inside MCR.
It does not govern:
• final canon-level enforcement rules by itself
• direct business execution
• campaign management
• capital allocation
• compliance rulings
• HeadOffice override authority
Those remain governed by SIT Brain Canon, MWMS Canon, HeadOffice, and related governance documents.
Definition / Rules
Core Principle
SIT Brain exists to validate structural truth.
Its purpose is not to make the system look tidy.
Its purpose is to detect whether the system is actually operating in line with declared rules.
Architectural Role
SIT Brain is the integrity architecture layer for MWMS.
It exists to ensure that:
• schemas remain compliant
• routing remains correct
• lifecycle movement remains valid
• decisions are logged correctly
• signals are recorded consistently
• cross-brain interactions remain structurally legible
• append-only and integrity rules are not silently broken
Relationship to MWMS
MWMS defines the system.
Brains define bounded domains.
SIT Brain verifies whether those structures are being followed correctly.
MWMS describes what should exist.
SIT Brain checks whether reality still matches that design.
Structural Domains of SIT Brain
SIT Brain architecture operates across five domains:
Foundation
Defines SIT identity, authority, log structure, and operating runbook.
Schema & Structural Enforcement
Validates task schemas, event schemas, append-only structure, routing maps, and cross-brain consistency.
Workflow Integrity
Validates lifecycle progression, decision records, signal logs, and experiment registry discipline.
Monitoring & Visibility
Surfaces integrity status, active violations, escalation triggers, and validation dashboards.
Advanced Enforcement Support
Supports interaction audits, automation safety checks, data flow integrity review, rollback validation, and drift detection.
Build Discipline Rule
SIT pages must be created only when the related system component exists or is close enough to active use that validation adds operational value.
SIT must not be expanded for appearance only.
It must expand in step with live system complexity.
Output Posture
SIT Brain produces:
• validation structures
• integrity checks
• enforcement support definitions
• monitoring surfaces
• escalation support logic
SIT Brain does not produce:
• strategy choices
• campaign recommendations
• persuasive output
• growth decisions
• offer approvals
Relationship to Other Brains
HeadOffice governs SIT authority.
MWMS defines the wider architecture SIT verifies.
Affiliate, Research, Ads, Experimentation, and Finance produce system behaviour that SIT may validate.
SIT checks structure.
It does not replace the operating role of any other Brain.
Future Build Logic
SIT Brain may later contain:
• SIT Brain Canon
• SIT Brain Employee Registry
• SIT Brain Runbook
• SIT Brain Log Schema
• SIT Brain Task Schema Compliance Checks
• SIT Brain Event Schema Compliance Checks
• SIT Brain Append Only Enforcement Validation
• SIT Brain Routing Validation Map
• SIT Brain Cross Brain Consistency Checks
• SIT Brain Workflow Integrity Tests
• SIT Brain Lifecycle Transition Validation
• SIT Brain Decision Logging Validation
• SIT Brain Signal Logging Integrity Monitor
• SIT Brain Experiment Registry Validation
• SIT Brain Integrity Dashboard
• SIT Brain Active Violations Register
• SIT Brain Validation Status Board
• SIT Brain Escalation Trigger Monitor
• SIT Brain Brain Interaction Audit
• SIT Brain Automation Safety Checks
• SIT Brain Data Flow Integrity Monitor
• SIT Brain Recovery and Rollback Validation
• SIT Brain Drift Detection Register
These pages should be created progressively, not all at once.
Final Rule
SIT Brain must remain a structural integrity architecture layer.
It exists to verify that MWMS behaves according to declared rules, not to become another decision or execution brain.
If the system becomes more complex, SIT may expand.
If the system remains simple, SIT should stay lean.
Drift Protection
The system must prevent:
• SIT drifting into strategy or execution
• validation pages being created before they are useful
• integrity checking being treated as optional
• hidden schema drift
• silent routing changes
• missing decision logs
• unvalidated lifecycle movement
• cross-brain inconsistencies being ignored because the system appears to work
SIT Brain must remain structure-first.
Architectural Intent
SIT Brain exists to give MWMS a dedicated integrity architecture layer that can grow with the system.
Its role is to ensure that task schemas, event schemas, routing logic, lifecycle progression, signal logging, and decision records remain aligned with the declared system design as MWMS moves from architecture into live operation.
