diegosouzapw Decision Journal Maintenance for accessibility services
Why This Skill Exists
This skill hardens a generated capability for production execution so accessibility services workflows remain deterministic, auditable, and fail-closed under risk.
When To Use
Use this skill only when the request explicitly needs Decision Journal Maintenance for accessibility services in accessibility services and a downstream consumer requires contract-bound artifacts.
Step-by-Step Implementation Guide
- Validate production trigger criteria: explicit capability request, approved source-tagged inputs, and named downstream consumer.
- Enforce deterministic normalization workflow with pinned mapping/ruleset versions and stable serialization order.
- Apply explicit determinism tolerance checks (score delta <= 0.005 absolute; identical input must produce zero artifact hash drift).
- Execute fail-closed validation gates (schema, determinism, policy-risk) and block output on any failure.
- Require explicit human sign-off token for high-risk runs before publication or downstream routing.
- Emit handoff envelope with artifact paths, gate results, risk tier, and approval state for the next stage.
Deterministic Workflow Constraints
- Replay score variance: <= 0.005 absolute per item.
- Artifact hash drift for identical replay: 0 allowed.
- Time-dependent fields allowed only in metadata and excluded from scoring.
Validation Gates
- schema-gate — all required fields present and schema-valid; otherwise block and return error bundle.
- determinism-gate — replay output within tolerance; otherwise quarantine and escalate.
- policy-risk-gate — policy and risk checks pass; otherwise block routing.
- approval-gate-high-risk — if risk is high, require human sign-off token; otherwise fail closed.
Handoff Contract
- Inputs: source-tagged signals, claims, evidence, confidence traces, run context.
- Outputs: deterministic artifact, scorecard, and handoff envelope with approval metadata.
- Routing rule: forward only when every gate passes; high-risk requires explicit sign-off token.
