fix(ci): run the authorization gate's diagnostics on a real mismatch - #3880
Conversation
The gate's step runs two independent commands over the same surface: `go test` is the verdict, and `go run` is the only caller of surfaceMismatchReport, the moved-entry diagnostics added in #3836. A real aggregate mismatch fails BOTH, and the step stopped at the first -- so on exactly the failure the diagnostics exist to explain, they never ran. Measured on #3878 (CI run 35257229458, job 105324573289): the approval base checked out fine, `go test` failed with a4781e58, and zero moved-entry lines were emitted. Identifying the one entry that moved took a purpose-written conservation render, which is the cost #3836 set out to remove. Both commands now run unconditionally and the step fails if either did. The cd.yaml copy had the same ordering and gets the same treatment. The new test executes the extracted step against stub `go` and `git` binaries under the runner's own shell flags, so the assertions are about behaviour rather than YAML shape: which commands ran, and what the step exited with. Each is ablated -- swallowing the status fires the negative control, and removing the diagnostics call fires the short-circuit assertion.

📝 WalkthroughWalkthroughThe CI and CD authorization validation steps now run the verdict and moved-entry diagnostics commands independently. Each step records command failures and exits nonzero if any command fails. CI adds an unconditional shell test that extracts both workflow steps, runs them with stubbed commands, checks failure and diagnostic behavior, and verifies that the previous short-circuiting form fails the test.

[warning] 110-110: set +e (or set +o errexit) disables the shell's errexit option, so the script keeps running after a command fails. This masks failures of security-critical operations (downloads, signature/checksum verification, permission changes, cleanup of secrets), letting the script proceed with a bad or insecure state. Leave errexit enabled (set -e / set -euo pipefail), or handle failures explicitly with if/|| and an explicit exit instead of globally turning off failure detection.

… can break The step's contract is that both commands run and the step fails if either did. Its test covered a failing `go test` in both directions but never the mirror -- `go test` passing while only `go run` fails -- which is the half the diagnostics themselves live in. Cases A, B and D are all satisfied by a step that ignores `go run` entirely, so swallowing its failure would have landed silently and the moved-entry diagnostics would have stopped being checked at all. Ablation: replacing `|| status=1` with `|| true` on both `go run` lines fails the new case on ci.yaml and cd.yaml and leaves every other case passing. Dropping the `||` clause outright does not fire it, because `set -e` then aborts the step anyway -- which is why the case is written against the swallow.

Motivation
When a change moves the platform's pinned authorization fingerprint, the security gate
fails and says only that the number changed — not which of the ~570 rendered resources
moved. Work to name the moved entry shipped earlier, but it has never actually run: the
gate's two commands were chained so that the first failure stopped the step, and a real
mismatch fails both. The command that produces the explanation was always the second one.
The cost lands on whoever has to review the re-approval. Four changes today each had to
re-derive by hand what the gate already knew, and a re-approval reviewed without that fact
is a rubber stamp — the exact erosion this control is meant to resist.
Changes
Both commands now run, and the step still fails if either did. A new test drives the real
step against stand-in tools and checks what actually happened, so the short-circuit cannot
come back unnoticed.
