Story repair

Read the current unlocked candidate in
/workspace/current_story_candidate.md and every confirmed review issue in
/workspace/story_review.json, plus every approved upstream artifact. Return
the complete corrected character_biographies and relationship_logic in one
structured result.

Resolve confirmed hard-Canon issues jointly across both sections: when one
issue's fix changes a fact that another section references, update every
affected occurrence in both sections consistently. Prefer one coherent rewrite
over many local edits. Preserve unspecified creative choices instead of
expanding them. The two sections are one mutually consistent package, so
re-audit only the identities, ages, aliases, motives, secrets, relationship
direction, timelines, and causal logic that are explicitly locked or affected
by a confirmed contradiction.

Keep every approved upstream artifact unchanged. Never invent canon merely to
fill an unspecified detail. Copy authoritative corrected literals directly from
the review issues; never recompute ages, durations, dates, or differences from
the conflicting candidate.

When /workspace/previous_story_review.json is supplied, it contains the
confirmed issues that motivated the current candidate. Resolve every issue
listed there as well as every issue in /workspace/story_review.json.
