File	Purpose
windows.endor	Two real native windows in one Aster VM, live shared counter state and explicit Page ownership.
tabs.endor	Three real Page tabs, shared counter state, source titles, native switching/closing and reopening through code.
window.endor	A managed native Window resizes the actual shell; source callbacks update it and layout follows reported dimensions.
layout-cache.endor	Per-occurrence source measurement caches, separate size/paint models, and a band using the logical viewport input.
source-layout.endor	Source measurement reads its initial Mount parent; source arrangement moves a child and a click updates the shared layout model.
source-hit.endor	Source circle hit testing, ordinary Block click subscriptions and fallback to the parent through transparent space.
source-paint.endor	Source paint overrides render checked commands in the window; a source Button method updates the shared tint model.
visual-protocols.endor	Real source calls for constrained native measurement, arrangement and managed paint-command results from live Mounts.
mount-lifecycle.endor	Source onMount/onUnmount methods, two occurrences of one object, ordered notifications and retained Mount lifetime.
events.endor	Managed event subscriptions, source onEvent override and numbered capture/target/bubble steps from native input.
native-subclasses.endor	Real native TextBlock/Button/Page source subclasses, inherited fields, method overrides and shared field bindings.
classes.endor	Endor class fields, inheritance, overriding, a retained receiver and Event arguments; native keyboard input updates shared model properties.
managed-types.endor	Callable managed Endor types, one shared counter, two bound displays and a language callback invoked from native Button input.
page.endor	Four top-level statements construct text, a rectangle and a page, then call page.render; no main wrapper.
main.endor	The earlier function-entry form, producing the same frame as page.endor.
hello.endor	Richer function-entry example covering a helper, Row/Column and Spacer.
fonts.endor	Mixed Chinese/Latin text and proportional widths, with rectangles following narrow and wide letters.

Submit a file as the UTF-8 body of a namespace PUT request. No namespace, scene, render block or imports belong in the source.

The live /agent guide embeds page.endor exactly. Remote CI executes the examples through Aster and checks the resulting coordinates and source ranges after VM cleanup. The file is client-side sample material; Tessera's API stores source by namespace.
