## Thinking Path > - Paperclip lets people manage AI agents and give them more instructions during work. > - The task composer sends those instructions through the shared Markdown editor. > - The editor writes a final text space as the HTML entity ` `. > - The composer trims spaces before it submits a message. An entity survives this step. > - Queued messages can therefore contain extra text that the person did not type. > - This pull request restores final prose spaces at the editor output boundary. > - The queue and the agent receive clean message text. Code and escaped examples keep their source. ## Linked Issues or Issue Description **What happened?** A message that ends with a space can contain a final ` ` when it enters the steering queue. The shared editor exports this entity, and normal message trimming does not remove it. **Expected behavior** The editor must return final prose spaces as spaces. Code samples and escaped literal entities must keep their exact text. **Steps to reproduce** 1. Open a task while its agent works. 2. Type a steering message with a space at the end. 3. Submit the message to the queue. 4. Inspect its stored Markdown. Before this fix, it can end with ` `. **Paperclip version or commit** Reproduced from `70d23612dd` with the installed Markdown serializer. The serializer writes `Steer the current turn ` as `Steer the current turn ` plus a newline. Searches for related trailing-space and steering-entity PRs found no duplicate. ## What Changed - Restore trailing space entities only in the final Markdown text node. - Apply this step before the editor removes its other transport escapes. - Keep code, raw HTML, escaped entities, links, internal entities, and hard breaks unchanged. - Limit the fix to an entity at the end of the message. Keep entities before internal newlines or closing emphasis markers. Replacing those entities with spaces can create hard breaks or remove bold and italic formatting. Add tests for these limits. - Add editor regression cases and focused Markdown cases. Keep the fix in the shared editor; no queue API change is needed. ## Verification - TDD: the new editor test failed in 3 cases before the fix. It received literal entities instead of spaces. All 6 cases pass after the fix. - All 353 focused editor, Markdown, composer, and queue tests pass. This includes 10 new cases for internal newlines, emphasis, and a final space after these cases. - `pnpm check:token-gates` and `git diff --check` pass. - UI typecheck and UI production build pass. - Repository typecheck and build could not complete locally because Cargo is not installed. The full test command was started, then stopped after confirming its native Runner cases also need Cargo. No complete local full-suite verdict is claimed. Current-head [CI](https://github.com/paperclipai/paperclip/actions/runs/42229743296) passes for `350af775850664226d6630072cb8e08732e2a218`. This includes typecheck, build, tests, and E2E checks. - [Greptile](https://github.com/paperclipai/paperclip/pull/19456#issuecomment-6686109030) and [Paperclip review](https://github.com/paperclipai/paperclip/pull/19456#issuecomment-6686063906) each score the current commit 5/5. No review threads remain open. - Checked the design-review dependency claim against the current commit. [ui/package.json already declares the parser](https://github.com/paperclipai/paperclip/blob/350af775850664226d6630072cb8e08732e2a218/ui/package.json#L71). The existing underscore helper uses the same parser. Six direct checks also pass for GFM strikethrough, task lists, URLs, and tables. - No visual style changed. No database or API contract changed. The helper comment documents the storage rule. ## Risks - Low risk. The change only restores encoded spaces at the end of the document. Internal line endings and spaces inside emphasis are out of scope. The tests keep these entities unchanged to preserve Markdown formatting. Parser source positions protect code and HTML. Escape pairs protect literal entity examples. - Existing stored messages are not rewritten. They use the corrected output after an editor change. ## Model Used - OpenAI Codex, GPT-6. GPT-6.1 Sol (`gpt-6.1-sol`) assisted with the review follow-up. The runtime does not expose the context-window size. Used reasoning, repository tools, code execution, and test execution. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>

What gets published
The npm package contains the production build under dist/. It does not ship the UI source tree or workspace-only dependencies.
Storybook
Storybook config, stories, and fixtures live under ui/storybook/.
pnpm --filter @paperclipai/ui storybook

Typical use
Install the package, then serve or copy the built files from node_modules/@paperclipai/ui/dist.
Editor dependency identity
Keep the root and workspace overrides for @codemirror/state,
@codemirror/view, and @lezer/common aligned. CodeMirror requires shared
extension identity, while Lezer parsers and syntax highlighters require shared
NodeProp IDs. Multiple Lezer copies can crash code-block highlighting with
tags is not iterable. src/lib/codemirror-single-instance.test.ts checks the
installed dependency graph and highlights sample code through the editor's real
language dependencies. GitHub Actions owns regeneration of pnpm-lock.yaml.
