📝 Summary

Pins the registered runtime identities inventory ordering and non-emptiness:

• RegisteredRuntimeIdentities() in internal/reviewerprovider/runtimes.go documents a stable lexical order, and validateEntries in internal/providercontractbundle/bundle.go validates decoded.Runtimes order-sensitively using slices.Equal.
• In internal/cli/review_transport_capability_test.go, removes pre-sorting before comparison so RegisteredRuntimeIdentities() is asserted directly against the sorted compiled transport boundary, and adds non-empty cardinality and strict sorting assertions.
• Adds TestRegisteredRuntimeIdentitiesStableLexicalOrder in internal/reviewerprovider/runtimes_test.go to pin non-emptiness and strict lexical ordering at the provider level.
• Adds TestVerifyArchiveRejectsMismatchedRuntimeInventory in internal/providercontractbundle/bundle_test.go testing reordered, empty, nil, and unknown runtimes rejection by VerifyArchive, along with manifest non-empty and order assertions in TestGenerateIsDeterministicAndVerifiable.

📂 Changes

File / Area	What Changed
internal/cli/review_transport_capability_test.go	Assert RegisteredRuntimeIdentities() is non-empty, strictly sorted, and matches compiled supported runtimes without sorting registered first
internal/providercontractbundle/bundle_test.go	Assert generated manifest runtimes order/non-emptiness; add table tests verifying archive rejection for reordered, empty, nil, and unknown runtimes
internal/reviewerprovider/runtimes_test.go	Add unit test pinning non-emptiness and strict lexical sorting of RegisteredRuntimeIdentities()

📝 Walkthrough

Walkthrough

The tests now enforce non-empty, strictly lexical runtime ordering and validate that generated bundle manifests match the registered runtime inventory. Archive verification tests reject reordered, empty, nil, and unknown runtime inventories.

Changes

Runtime inventory validation

Layer / File(s)	Summary
Runtime ordering contract internal/reviewerprovider/runtimes_test.go, internal/cli/review_transport_capability_test.go	Tests require registered runtime identities to be non-empty and strictly lexically sorted. Capability comparison sorts only the compiled list.
Bundle manifest validation internal/providercontractbundle/bundle_test.go	Bundle tests verify the manifest runtime inventory against registered identities and reject reordered, empty, nil, or unknown inventories.

Priority: ➖ Normal

- Around line 323-326: Update the test cases around the runtime comparison to
derive their inputs from a clone of
reviewerprovider.RegisteredRuntimeIdentities(). Swap two entries for the
“reordered runtimes” case, and append “unknown-runtime” to the canonical list
for the “unknown runtime” case, preserving the empty and nil cases.

Rebased onto upstream/main cleanly. All CI tests pass (18/19 checks green).

Could a maintainer please add the type:chore label to satisfy the label check?
