nuif-canva
nuif-canva is the credential-free, normalized boundary for the bounded Canva
Design Editing profile nuif-canva-design-editing-0. It is deliberately a
library adapter, not a Canva SDK client: a host integration supplies a current
page snapshot, and the adapter returns a validated nuif-core::Document plus
HostAdapterReport correspondence and fidelity evidence.
The profile currently maps one fixed-size page with an optional opaque sRGB background, nullable page/element names, ordered groups, rectangles, ellipses and literal text using the pinned profile font. It rejects locked content, unsupported properties, invalid geometry, nonopaque colors and unbounded input before a host mutation could be attempted. IDs exported by NUIF use an explicit round-trip marker so repeated import/export does not invent new identities.

fn main() {
let imported = nuif_canva::import_current_page(snapshot_bytes)?;
let exported = nuif_canva::export_page(&document, "2026.1")?;
}adapters/canva/app is the thin Canva Apps SDK consumer. Its live mutation
subset is narrower than this normalized mapping: an empty same-size page,
nullable page name, unnamed opaque rectangles/canonical ellipses and an
optional opaque background. Text and groups remain pure-mapper fixtures until
the public host API can prove the identity and metrics the profile requires.
The adapter does not claim a live Canva run, marketplace approval, Connect API NUIF import/export, or a native Canva file format. Those require retained owner/reviewer host tests and remain outside credential-free CI.

The gate writes the pure mapping report, Rust/TypeScript plan and round-trip
fixtures, target/canva-app-shell-report.json, an informational scaling report
and target/nuif-canva-review-app. The packaged app carries Canva’s SDK license
and is restricted to permitted apps on the Canva Platform. Every live_host
field remains not_run until a named runtime and API version have been tested
by a human reviewer.
