Update public-boundary expectations after the explicit XML unknown-scalar
and native UI deadline provenance changes. Retain raw malformed literals,
independent exact integers, expanded-year ISO dates, and partial UI reports.
Assert successful cleanup releases its lease and failed cleanup retains it
until close retries. Keep malformed-input and true date-range coverage.
The shared number fixture owns CLI/filesystem/MCP expectations. Native
plutil controls confirm integer entities are invalid plist literals, even
though they are valid XML. No runtime behavior or CI gates change.
Validation: 187 source cases, 138 focused public cases, final 97-case
rerun after fixture typing/group changes, full static/architecture checks,
and test discovery (1591 files).
Carry caller and runtime deadline cancellation through helper cleanup, preserve command-owner reasons and physical failures, and retain collected scenario reports with typed terminal errors.
BREAKING CHANGE: failed or cancelled native UI scenarios now return typed errors with the collected report in partial_observation instead of successful reports containing failed or cancelled steps.
