🟢 95-100% confidence

Phase	🧪 Tests	🌐 Browser
Reproduced	🔴 focused registry regression failed	➖ N/A
Verified	🟢 bun check	➖ N/A

✅ Outcome

• kitcn add auth --preset convex reuses existing authSchema imports with either quote style.
• Added regression coverage for double-quoted authSchema imports.
• Added patch changeset.

🏗️ Design

• Chosen seam: raw Convex schema registration builder.
• Why not quick patch: exact string matching caused the duplicate.
• Why not broader change: AST rewrite is overkill for one import guard.

🧪 Verified

• bun check
