Working browser surface: Field guides — documentation — Inspect the guide and persist local checkpoints. This route is local-only; provider, credential, database, customer, publication, deployment, and production effects remain held.
Authoritative tools lane tools and interfaces
Canonical tools-page assignments
- Notebook Field Guides (interface · optional) — Compose the source-backed procedure, prerequisites, bounded steps, related projects, and instrument links; do not use it as evidence that implementation is deployed.
- Notebook Notes (interface · optional) — Record Apple platform observations, source locators, revisions, and explicit claim boundaries; do not use notes as authoritative provider or production state.
- Notebook To-dos (interface · optional) — Track implementation slices, qualification work, owners, priorities, due dates, and human-review signals; do not turn them into hidden automation.
- Notebook Approvals (interface · optional) — Hold and review proposed native capability claims with preserved receipts; approval is local review and not deployment or publication.
- PointGuard (interface · optional) — Carry the current iOS implementation context across Guth surfaces while specialist apps remain canonical record owners; do not treat it as the execution owner.
- Finite State Machine Simulator (provider · optional) — Model explicit SwiftUI and app-flow states such as proposed, indexed, prototype, held, unavailable, needs review, and approved; do not use it to prove runtime behavior or platform support.
- WCAG Contrast Ratio Checker (provider · optional) — Check proposed foreground/background pairs and document accessible contrast targets; do not use it as a complete accessibility audit or as proof of VoiceOver, Dynamic Type, or native UI compliance.
- Checksum Verifier (provider · optional) — Verify recorded source hashes and detect accidental evidence changes; do not use it to establish source authority, authenticity, deployment, or database integrity.
Only the page's admitted lane is rendered as an assignment. Other lane inventories remain source records but are not merged here. Tool kind and required/optional status are preserved.

An instrument listed only for another lane does not become a tools-page assignment.
Use boundary
- A named iOS or SwiftUI surface may be mistaken for a connected web feature.
- Prototype or indexed routes may be mistaken for deployed product behavior.
- Instrument outputs may be overgeneralized into production, safety, accessibility, or platform-compatibility claims.
- Stale source locators or hashes can make implementation notes non-reproducible.
- State models can omit permission denial, unavailable capability, offline, and held-effect paths.
- Local approval can be misrepresented as Apple qualification, provider connection, publication, or production readiness.
- Accessibility checks limited to color contrast can miss semantics, VoiceOver behavior, Dynamic Type, motion, and input modality issues.
- Native implementation work can drift from canonical record ownership if PointGuard is treated as the execution owner.
