# ios-ipados-platform-extension

## Role

This focused Layer 3 Domain Skill supports `analysis-agent`, `task-agent`, and
`review-agent` for a confirmed iOS/iPadOS target. The selected Professional
remains owner; this root never selects a new route or review owner.

## When To Use

- Confirmed Apple mobile lifecycle/background, entry/entitlement, data/keychain,
  UI/accessibility, compatibility/distribution, or special-platform behavior changes.

## Do Not Use

- Web/PWA, backend, infrastructure, non-iOS/iPadOS, or language/framework-only
  work without a confirmed target; signing, store, release, or rollout authorization.

## Required Inputs

- Target/device family, OS/SDK/deployment, app/scene owner, active decision family,
  accepted carrier, identity/artifact/device evidence, and proof limits.

## Professional Decision Rules

- Analysis loads only active decision-family References.
- Task and Review load paired evidence companions through the accepted carrier.
- Preserve Professional and Foundation ownership.
- Preserve all simultaneous families.
- Never reopen routing or infer watchOS, tvOS, or visionOS coverage.

## High-Value Gotchas

- Simulator, debug, or one device proves neither archive identity nor lifecycle,
  extension, accessibility, background, or mixed-version behavior broadly.

## Execution Checklist

1. Confirm target and active families from repository and artifact facts.
2. Load only the role-valid decision or evidence Reference set.
3. Record artifact/device validation, non-inferences, and proof limits.

## Stop / Escalation Conditions

- Stop on an unresolved target, owner, boundary, accepted decision, or carrier.
- Stop when required archive or device evidence is unavailable.
- Return release authorization to its owner.

## Output Contract

- iOS/iPadOS owner and scoped decision/evidence, normal and failure behavior,
  artifact/device validation, source freshness, proof limits, and residual risk.
