XcodeBuildMCP Snapshot Fixture Review

Review guardrails for fixture and snapshot contract integrity.

Review scope

Review-only by default.
Do not edit product code unless the user explicitly requests implementation changes.

Guardrails

Fixture updates map to intentional behavior changes.
Do not update fixtures only to make tests pass.
MCP, CLI, and JSON fixture updates stay aligned.
JSON fixtures preserve stable structured output envelopes.
Volatile values are normalized in code, not patched ad hoc in fixtures.
Missing fixtures are generated through the snapshot update flow.
Verify project-defined normalization sentinels in normalization code and tests before reporting them as implausible fixture values. In particular, 99999 is an intentional sentinel for volatile UI capture counts.
Group every occurrence of the same root cause into one finding and list the affected fixtures. Do not emit separate findings for equivalent CLI, MCP, text, or JSON drift.
Do not repeat a finding that is already resolved by the current diff.

Review limits

Review the changed fixtures and the directly relevant normalization or contract code only.
Do not run snapshot or smoke suites as part of an automated PR review.
Prefer one high-confidence cross-fixture finding over multiple speculative discrepancies.
