pj b1e95739ad feat(hierarchy): an element reports whether it masks what is typed into it
ios reads it off SecureTextField, which the companion already sent and
nothing read; web reads input[type=password]. Android cannot: the native
tree mapper drops the password attribute before the sidecar sees it, so
the fact is three-valued and null there rather than a false that would
read as "not secure".

@sanderling/spec

TypeScript spec API for sanderling, a property-based UI fuzzer for Android, iOS and web apps.

A spec exports properties (what the app must always or eventually do), extractors (structured state read off the UI), and action generators (what sanderling is allowed to do). The sanderling CLI evaluates the spec against a running app once per step.

npm install --save-dev @sanderling/spec

Getting started installs the CLI and runs a first spec. The spec language reference lists every primitive, and the case study walks a complete spec end to end.

The CLI bundles this package's TypeScript sources at run time, so keep the CLI and the package on the same release.
