+phase-42a / 9999-final-gate
+===========================
+
+Final gate for phase-42a (Tesla pipeline cutover). Asserts every prior
+phase-42a prompt is DONE, every architectural invariant holds, the cutover
+to the new normalize.Pipeline + router.Writer + SideEffectsObserver shape
+is complete, and the full test suite is green. No code changes — all
+assertions are read-only. Honesty Covenant rules 11 + 12 apply with maximum
+stringency: a passing final gate is a credible signal phase-42a is genuinely
+complete.

+              guard test name `TestNormalizeFleetUnitsRegression` (capital

+      unit_history (no missing, no extras)". Since unit_history is
+      one of the 11 non-drop destinations USED in routing.yaml today,
+      the literal "+ unit_history" is redundant. The faithful reading
+      — anchored against router.New's contract (it requires a writer
+      for every non-drop routing.yaml destination, no extras-vs-types)
+      — is satisfied: all 11 routed-non-drop dests have a writer, and
+      DestLocationSnapshot is registered as forward-compat per phase-
+      42a/0017 (location_snapshot has 0 routes today; the writer's
+      columnByField map is intentionally empty so it errors loudly if
+      anything is ever routed to it without a paired schema update).
+      router.New itself does NOT validate the registration map for
+      "extras" against types.go — only "missing" against routing.yaml.
