## Thinking Path > - Paperclip lets people manage AI agents and their work. > - The issue page uses an external-store adapter for comments. > - The adapter must keep one identity during an unrelated render. > - The adapter must also call the newest send and cancel functions. > - Passive effects update those functions too late for a synchronous runtime call. > - This pull request updates the function refs during render and adds a regression test. > - The benefit is a stable comment thread with no stale comment action. ## Linked Issues or Issue Description Refs #3678 **What happened?** The issue comment runtime can call the prior send function after a render. The callback refs do not update until passive effects run. **Expected behavior** The stable runtime adapter must call the newest function as soon as the render supplies it. **Steps to reproduce** 1. Render the issue runtime with one send function. 2. Render it again with a new send function and the same thread data. 3. Call the stable adapter before passive effects run. 4. Observe that the prior send function runs. **Paperclip version or commit** `6395cae072` **Deployment mode** Local development from source. **Agent adapter(s) involved** This is a core UI bug. It is not adapter-specific. ## What Changed - Update the latest send and cancel refs during render. - Keep the external-store adapter stable across callback-only renders. - Add a test for a runtime callback before passive effects run. ## Verification - `pnpm --filter @paperclipai/ui exec vitest run src/hooks/usePaperclipIssueRuntime.test.tsx` - `pnpm --filter @paperclipai/ui typecheck` - `pnpm check:token-gates` - `pnpm -r typecheck` - `pnpm test:run` - `pnpm build` ## Risks - Low risk. The change only updates two refs earlier in the same render. - The adapter identity and its data dependencies do not change. > This bug fix does not add or overlap with a roadmap feature. ## Model Used - OpenAI Codex with GPT-5. The exact deployed model ID and context window are not exposed. Reasoning, tool use, and local code execution were enabled. ## 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/.

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.
