nsx-ambiq-sdk 5.2.24 — AmbiqSuite stable-2026.06.18

Immutable provenance-correction release for the AmbiqSuite stable-2026.06.18 payload.

• Preserves the ABI-correct binary payload from v5.2.23 byte-for-byte.
• Corrects 22 stale ACfE artifact-manifest hashes and records ABI provenance.
• Adds real-payload manifest verification to prevent recurrence.
• v5.2.23 remains published and immutable.

This release records the exact promoted stable snapshot honestly. It does not claim that the payload is an official numbered AmbiqSuite release.

Qualified scope

The repository-level baseline qualifies staged descriptors, promoted artifacts, NSX wrappers, and representative links for Apollo2, Apollo3, Apollo4, Apollo330, and Apollo510 platforms. Repository CI passed on Python 3.10 and 3.12, and representative GCC 15.2.1, ATfE 22.1.0, and ArmClang 6.24.0 link smokes passed.

Exclusions and hardware evidence

• apollo5b / apollo5b_evb remain descriptor-only and are not configure/link qualified.
• atomiq110 / atomiq110_fpga_turbo remain experimental and are excluded from the official qualified scope.
• Hardware evidence is limited to the feature-level results documented for bounded _sbrk selection and selected PSRAM configurations. This is not blanket board-level or vendor SDK hardware qualification.
