# HyperTwist Phase S4-B Preparation Packet

Date: `2026-05-29`

Packet: `Phase S4-B`

Title: `first-party browser diagnostics skills`

## Goal

Land the next bounded browser/docs/design skill seam by exposing first-party
browser diagnostics skills over authoritative HyperTwist browser, service, and
artifact source surfaces.

## Scope

- `skill/capture-browser-trace`
- `skill/discover-browser-api`
- first-party browser diagnostics state over authoritative first-party
  browser/service source surfaces
- registry, control-state, audit-ledger, authoring-harness, sample-contract,
  and JSON support

## Required boundaries

- do not widen into design-to-native translation
- do not widen into broad browser-shell orchestration
- keep browser diagnostics provenance-visible, bounded, derived-assistive, and
  first-party owned

## Inputs

- landed `S1-A` through `S4-A` skill substrate
- landed first-party architecture, roadmap, feature-registry, and provenance
  authority surfaces

## Acceptance gate

- browser diagnostics remain bounded to trace capture and browser/API
  discovery and do not claim design translation ownership
