Replaying run 36385945043's two Design attempts showed the existing routes
rejected correct endings: attempt 1 at the typed-completion path field
('- Reviewed plan written to …' is not a 'Plan written to' line), attempt 2
at the leading-fence veto (its final message opens with the dashboard).
nativePlanTerminalPreconditions is the structural prefix of
hasNativePlanTerminal (behavior unchanged). structuredPlanCompletion adds,
inside the existing nativeSummary branch: a complete report (Design
binding for Design), a completed review-log row for the expected skill
appended during this attempt under the child's GSTACK_HOME/project slug
(resolved with bin/gstack-slug) and stamped with the fixture commit, timed
between the report/last answer (second resolution) and the final native
message, a final message with stop_reason end_turn (now carried on public
transcript messages), and no visible question or permission prompt.
Timeout summaries add idleFor and lastTerminalCandidate. Terminal and throw
captures copy the plan file and review-log rows into the artifact
directory; copies are best-effort and recorded in evidence-copy.json.
Free regressions: both captured Design endings (trimmed fixture with
provenance; report, row and end_turn reconstructed and labelled), the
negative controls, and real-PTY completion/timeout runs through the real
review logger.
