Summary

A Clang offload bundle containing only its header could declare an impossible directory count and report a resource limit. Check the raw uint64 declaration against the available minimum row extent before numeric conversion and capacity admission. A malformed file now reports a format failure; framed oversized directories keep their existing capacity refusal.

Each entry needs three 64-bit fields before its ID, as defined by the LLVM offload bundler. No new cap is added.

Validation and scope

The public-provider regression failed before repair. Node24:117 focused GPU tests and check:fast passed, including count0, short count65537/uint64 maximum and a framed over-budget directory with ID bytes. That capacity fixture establishes framing, not runnable code or semantic uniqueness. No real GPU compiler/runtime qualification. Existing parser repair; no new target authority, dependency, schema, installation or generated metadata. Maintainer scope decision not applicable.

Author readiness

• I reviewed the final diff and relevant existing code, understand the change and its edge cases, and take responsibility for the complete PR, including AI-assisted work.
• I checked the evidence above, confirmed it supports the current change, and recorded meaningful validation gaps.
• I declare this PR ready for initial maintainer review.
