prompt: mask1d-shape-native-scalar-widening shipped to PR #485, awaiting merge

Both sites fixed and verified: test_autoarray 1201 passed / 0 failed, test_autocti
270/1 (pre-existing 2D serial-EPER failure, confirmed against canonical main), dataset_1d
simulator + modeling smoke pass, real-JAX tracer passthrough verified.

Workspace impact is none — autocti_workspace's ac.Mask1D subclasses aa.Mask1D and
inherits the fix, so no /start_workspace follow-up.

Merge is blocked on Heart red (`release validation FAILED`, an incomplete report unrelated
to this change). The PR was opened under an explicit human override rather than the
AUTONOMY.md corrective-PR exception, which does not apply here.

     The originating prompt shipped as #464 and is recorded at
     complete/2026/08/autoarray-pixel-scales-scalar-widening.md (backfilled — it sat in
     draft/ while the work shipped).
-    Next: /start_library → worktree + branch, then the two source edits and their tests.
+    SHIPPED to PR #485 (`c0c00b0e`), NOT merged. test_autoarray 1201p/0f; test_autocti
+    270p/1f (pre-existing 2D serial-EPER failure, confirmed against canonical main);
+    dataset_1d simulator + modeling smoke pass; real-JAX jit tracer passthrough verified.
+    Workspace impact: NONE (option iii) — autocti_workspace's ac.Mask1D subclasses
+    aa.Mask1D and inherits the fix; no /start_workspace follow-up.
+    Also tightened #464's own widening tests, which passed vacuously because
+    `np.float64(1.0) == (1.0,)` NumPy-broadcasts to a truthy `array([True])`.
+    MERGE BLOCKED: Heart red on `release validation FAILED` — an incomplete report
+    (0 failures, only `integrate` recorded, pre-dates this task) unrelated to the change.
+    PR opened under explicit human override, NOT the AUTONOMY.md corrective-PR exception,
+    which does not apply since this PR does not repair that reason.
+    Next: /prm once Heart clears — merge, close #484, record, remove worktree + branches.
