Visual Fidelity Practitioner Probes — Layered Judgment & Evidence

🧭

Contained, principal-level questions for scaling visual contracts beyond a design library. Each question compresses a governing decision, an ownership boundary, a plausible fault, and the evidence that would make the resulting claim credible.

Start with one material boundary

Bring a component, command, representation, or delivery proposal. Choose the layer that owns the next decision. Work through one question, state the decision rule, exercise a fitting fault, and return an observable oracle with its limits. A useful answer can be compact; its depth comes from the quality of the judgment.

This bundle retains the established anatomy and Levels 1–5 from 🔎Practitioner Probes and 🔎Start Here — How to Use the Probes.[1][2]

The ladder crosses the stack

Layer
Route
Compressed judgment
Browser substrate
Native semantics, token meaning, representation identity, owned JavaScript lifetime
Selected frameworks
React lifecycles and coherent state, Next.js boundaries, package semantics
Client middleware / BFF
Typed issue translation, cache scope, safe retry and receipt reconciliation
Back-end runtime / framework
Durable command identity, transactions, scalable projections, migration
AI and system collaboration
Bounded caller authority, safe state projection, claim/evidence fit, calm recovery

There are nineteen contained probes: four browser, four framework, three middleware, four back-end, and four AI/system questions. Layers describe technical location; Levels 1–5 describe answer depth within each question.

Levels 1–5

  1. Surface and meaning. Name the visible state and the decision it asks a person to make.
  2. Mechanism and owner. Explain which primitive, component, adapter, or service realizes it.
  3. Real use. Apply the mechanism to a realistic state transition with stable identities and revisions.
  4. Edges and coordination. Handle replacement, failure, changed audience, concurrency, versions, and maintenance.
  5. Evidence and handoff. Exercise a plausible fault, inspect a fitting oracle, state the claim limit, and hand off ownership.

Each module tailors these levels to its question and carries Question, Why this matters, Levels 1–5, Technical core, Review surfaces, Technical-veracity status, References/verification anchors, and AI instruction yield. It complements existing owners and routes the deeper harness work to those owners.

Veracity and release standing

The new questions are draft_probe: authored extensions awaiting a fitting local review. Their cited mechanisms may be source_supported; specific framework/runtime behavior is source_specific; application performance and durable outcomes are local_measurement_needed. A passing local HTML fixture covers its exercised specimen behavior. It leaves the receiving system’s claims with their proper evidence owners.

The framework selection uses the existing React, Next.js, Zustand/TanStack Query, and Django/FastAPI guidance. Middleware questions route to the vanilla ownership pages; the existing Middleware Frameworks scaffold retains its own readiness and human trust gate.

A benchmark count, schema result, screenshot, digest, or test suite establishes only its fitting claim. Choose the smallest evidence set that protects the consequential behavior and changes the next material decision.[3]
