- Line 1246: Update the group-acceptance condition in the parser to use
GetOptionSwitches(token).Count > 0 instead of
ContainsOnlyInlineOptions(nestedTokens), so mixed option/operand alternatives
such as --all|RESOURCE are rejected and handled by the existing
ambiguous-colon-group exception. Add a regression case covering the

Addresses the blocking unspaced-alternative finding in review #5147 (comment). Fixed in 2531958, verified at the remote PR head. Leaf classification now uses GetOptionSwitches, which shares the existing spacing-independent alternative parser and rejects mixed option/operand alternatives. The option-first unspaced regression failed before this change. All 150 synopsis tests now pass, including option-first/operand-first controls, spaced alternatives, unspaced option-only groups, nested list-valued selectors, and required-group rejection. Scoped severity-info formatting passes. |

Addresses the option-terminator finding in #5147 (comment). Fixed in 1e45215, verified at the remote PR head. Parsing an empty option-only group now preserves the pending terminator until a real operand consumes it. Both single-group and consecutive-group regressions failed before the fix; those cases and a no-terminator control now pass. All 153 synopsis tests and scoped severity-info formatting pass. The non-blocking classifier suggestion is left separate: the suffix predicate requires option-control tokens, while the whole-group predicate recursively accepts wrappers and separators. Both already use GetOptionSwitches for leaf alternative parsing; replacing either entire predicate with the other would change their distinct grammar rules. |
ReviewBoth previously flagged blocking issues are now fixed, with regression coverage for each.

The new CLAUDE.md compliance: the fix is applied to the generic parser/scraper logic (not hand-edited generated output), no I didn't find any correctness or compliance issues. I did not execute a build/test run against the PR's working tree myself (per the sandboxing constraints on this review), relying instead on manual trace-through of the changed logic against the fixtures/tests and the PR description's reported validation (178 focused tests passing, clean Release build, scoped format check). No blocking issues found. |

CI run 35018672593 exposed kubectl port-forward/debug regressions in the shared parser changes. Fixed in 00ffc96, verified at the remote head: gcloud declarations now reuse shared operand names, and optional forwarded groups retain their structure. Both failing kubectl tests and all 203 focused parser/resource/kubectl tests pass. The new required-colon-group review finding is also fixed, replied to, and resolved. Broader tests remain delegated to CI after the unchanged local 2 GB guard was reached. |

Also confirmed the two previously-flagged blocking bugs are actually fixed on this head, not just superficially addressed:
Incidental fix worth calling out: No blocking issues found on this head. Fixture and test coverage (gcloud compute ssh/scp, custom-jobs local-run, resource-manager tags, network-endpoint-groups) exercises the compound/grouped-operand paths this PR touches, and the changes stay within the scraper/generator per the repo's "fix the generic logic, don't hand-edit output" guidance. |

Preserves gcloud resource and compound operands in generated constructors and validation. The shared synopsis parser now retains required options, nested choices, and conditional optional bundles, while respecting option value shapes and alternate usage forms. Captured gcloud help covers SSH/SCP operands, resource selectors, nested bundles, and required constructor arguments; kubectl regression coverage protects shared operand naming.
Validation: 217 focused parser/resource/kubectl tests, 19 captured collection cases, and two compiled generated-validation cases pass. The generator solution builds in Release, scoped severity-info formatting passes, and the handwritten parser API additions are tracked. Broad generated-validation testing previously reached the repository's 2 GB guard, so the full suite runs in CI.
#5152 builds on this source fix to preserve command coverage with Google Cloud SDK 585.0.0. Merge both source fixes before regenerating the gcloud package from main; generated output is not patched here.
Closes #5145.
