Model-less appliance rebuild before managed-namespace change

Date: 2026-09-25

This result covers a status-only NativeActivity/CoreCLR/SMA base host built before the namespace changed to Dev.MansfieldPlumbing.Kokoro. The external Build directory was subsequently cleared. It does not establish that the renamed source has been built, model loading, direct Hexagon speech execution, or audible Kokoro synthesis.

The two Android header URLs in lib/pwsh-build-manifest.json were changed to GrapheneOS mirrors at the same pinned commits. Each fetched file matched its unchanged SHA-256 pin. Step 1 verified all 27 local specifications and all 22 remote source bytes. Step 2 verified 14 package SHA-512 catalog entries.

setup-kokoro.ps1 -Headless -Step 11 completed through APK Signature Scheme v2 verification. Its assembly-selection gate classified 101 ReadyToRun candidates but did not reject R2R images from the 96-assembly runtime store; a later PE-header audit found 62 selected R2R images. The resulting signed APK is 40,967,465 bytes, below 40 MiB, with SHA-256 868A887E04A0809C3178A25C9C312A226CD71442F97EDB3EDB294F834745CD2A. An independent ZIP read-back found 12 entries, no DEX or Mono/Xamarin native library names and no model-like payload name. The absence of a separately named ReadyToRun DLL did not establish an IL-only payload.

The same signed APK installed with package replacement and launched on both connected physical devices. Three seconds after launch, the application process was live on each. Test-ApplianceExpression.ps1 and Test-ProductionClosure.ps1 both passed; the former admits only status and the latter is a source-policy check, not a speech test.
