Purpose

• Other: isolate the manual suppression-policy review for ARM finding 6 from the executable server-compatible spec fixes in [ContainerService] Address server-compatible September ARM review findings #47509.

Targets dev-containerservice-Microsoft.ContainerService-2026-09, not main.
Review comment: #47398 (comment)

Changes

• Replace the blanket DefinitionsPropertiesNamesCamelCase suppression with exact JSONPath exceptions for enableRBAC and 23 published acronym spellings.
• Include Markdown in the existing AKS-local spelling dictionary override so the explicit legacy field names pass SpellCheck.
• No TypeSpec model, generated Swagger, wire format, SDK method or backend implementation changes.

The two-file delta is preserved byte-for-byte from the reviewed suppression proposal in commit ffe0dfd3d47bfd5efcab6cec79d7dc8fa68dbbe7; it was not discarded to hide a failure. The parent fixes PR now retains the dev branch's existing suppression policy unchanged.

Validation

• git diff --check passed.
• Exact comparison confirms this is the same two-file proposal previously validated by the repository's actual PowerShell SpellCheck script.
• A scan using the pinned validator's camelCase rule across all 121 existing managedClusters contracts confirms that every existing nonconforming acronym path is enumerated.
• Earlier same-validator September before/after checks showed no new diagnostics after scoping these exceptions.

Required human review

This PR deliberately remains draft and requires legitimate Approved-Suppression approval.
The reviewer must confirm the compatibility reasons and exact scope before granting the label. No approval is fabricated or applied by the authoring agent.

Separating this policy decision lets #47509 be tested independently without blocking its code fixes on a manual approval. It does not bypass, remove, or modify any CI check.
