Reliability Harness

Component id: reliability

Source contract: BlockContract for reliability.

Overview

mvp.reliability — Component Reliability Framework (CRF)

SP1 Core + SP2 Knowledge Layer + SP3 MCP Interface + SP4 Cross-Agent Routing exports. SP7 Scenario Library exports follow at the bottom.

Good at

  • envelope distribution / drill / summary queries
  • policy override management
  • scenario + recipe execution against persisted incidents

Not suited for

  • answering questions about envelopes that haven't been persisted yet
  • diagnosing failures outside the recorded reliability_incidents table

Inputs and outputs

  • Required: op
  • Optional: component, since, risk_tier, reliability_status, completion_state, incident_id, group_by
  • Outputs: MCPReliabilityOutput

Mitigates

Known Failure Modes

  • ledger_garbage: Stringified-dict payloads upstream cause claims_ledger splitting to emit garbage tokens.
  • envelope_drift: Persisted envelopes from an older schema may lack newer keys.

State Surface

  • Persistence: project
  • Queryable via: ledger
  • Retention: forever

Extension Points

  • training_signal_inputs: ('reliability_incidents', 'verification_reports')
  • validation_gate: meta_eval_suite
  • allowed_mutation_surfaces: ('scorecard_thresholds', 'report_templates')

Verification

  • Method: self_check_of_envelope_integrity
  • Human review gate: False
  • Fallback block: none
