## Thinking Path > - Paperclip orchestrates AI agents for zero-human companies > - The board and agent APIs accept multiline issue, approval, interaction, and document text > - Some callers accidentally send literal escaped newline sequences like `\n` instead of JSON-decoded line breaks > - That makes comments, descriptions, documents, and approval notes render as flattened text instead of readable markdown > - This pull request centralizes multiline text normalization in shared validators > - The benefit is newline-preserving API behavior across issue and approval workflows without route-specific fixes ## What Changed - Added a shared `multilineTextSchema` helper that normalizes escaped `\n`, `\r\n`, and `\r` sequences to real line breaks. - Applied the helper to issue descriptions, issue update comments, issue comment bodies, suggested task descriptions, interaction summaries, issue documents, approval comments, and approval decision notes. - Added shared validator regressions for issue and approval multiline inputs. ## Verification - `pnpm exec vitest run --project @paperclipai/shared packages/shared/src/validators/approval.test.ts packages/shared/src/validators/issue.test.ts` - `pnpm --filter @paperclipai/shared typecheck` ## Risks - Low risk. This only changes text fields that are explicitly multiline user/operator content. - If a caller intentionally wanted literal backslash-n text in these fields, it will now render as a real line break. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR.
