## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - The board's Retry is the one action a person takes when a task stops; it must either start work or say why it can't yet > - Restart chaos t05 left a parent task blocked on a blocked subtask. The board clicked Retry twice; each was accepted and nothing happened > - The Retry was saved and the queue deferred it behind the unresolved blocker, which is correct. But the task still looked failed with Retry offered, so the wait was invisible > - This pull request presents a saved Retry that waits only on unfinished blockers as waiting, names the blocked subtask and links it > - The benefit is that the board sees what to act on (the subtask's own Retry) instead of clicking a Retry that cannot run ## Linked Issues or Issue Description Refs #19831 (durable ownership plan). Restart chaos wave `w-20261108T200620-s9701`, task t05 (claude, M1, K4). **Problem:** parent CHA-5 was blocked by subtask CHA-10, which was itself blocked on a board recovery action. The board pressed Retry on CHA-5 at 20:27:46 and 20:40:46. Each `POST /issues/:id/retry` returned 202, and the saved Retry stayed `deferred_issue_execution` behind CHA-10, so no run started. The task's interruption presentation kept saying `failed` with `canRetry: true` and gave no reason. ## What Changed - `server/src/services/task-interruption-presentation.ts`: - For tasks with a saved (deferred, user-requested) Retry, the loader reads the queue's own dependency readiness (`listDependencyReadiness`). That counts cancelled blockers and done blockers whose workspace has not finalized, like the queue does. - When the saved Retry for the latest run is held only by unfinished blockers (no execution wait, no preparation), the task is presented as `working` with `canRetry: false` and `retryWait: { reason: "dependency_blocked", message }`. - The message has three forms: - a blocked blocker: "Retry or unblock it"; - a cancelled blocker: "Remove or replace that dependency to continue", because the queue keeps it unresolved; - otherwise: waiting for the blockers to finish. - The presentation carries no blocker names or ids. Issue reads return it to restricted agents too. - The Retry response (`POST /issues/:id/retry`) already returns this presentation, so the API says the Retry is waiting on dependencies as soon as it is saved. The blockers themselves are in the issue's `blockedBy`, which issue reads already filter per viewer. - `ui/src/components/ExecutionBlockerNotice.tsx` takes `blockers` (the issue's `blockedBy`, from `IssueDetail`). For a `dependency_blocked` wait it lists each readable unfinished blocker with a link and what it needs: "Blocked: open it to Retry" or "Cancelled: remove or replace it". Tokens only; `pnpm check:token-gates` is clean. - No shared type change, and no code comments added. ## Verification Red/green: - `server/src/__tests__/task-interruption-query.test.ts` "explains a saved Retry held by unfinished blockers instead of offering Retry again (restart chaos t05)". It sets up a parent with a failed run, a saved Retry deferred, and a blocked subtask that blocks it. - On master: `{ state: "failed", canRetry: true }`, no reason. - With this PR: `working`, `canRetry: false`, `dependency_blocked`. The presentation has no blocker title or identifier. - A cancelled blocker gets the remove-or-replace message. Once the blocker is done, the dependency wait is gone. - `ui/src/components/ExecutionBlockerNotice.test.tsx`: the notice links the blocked and the cancelled blockers with their actions, skips the done one, and offers no second Retry. Regression: `task-interruption-query` (25 tests) and `ExecutionBlockerNotice` (16 tests) pass, as do the presentation unit tests, workspace-recovery admission, gates and copyback tests, and `heartbeat-dependency-scheduling`. `tsc --noEmit` is clean for `server` and `ui`. ## Risks - One more batched read (dependency readiness plus blocker statuses), only for tasks in the page that have a saved Retry. - Presentation only. Admission is unchanged: the queue still runs the saved Retry when the blockers are done. - A Retry saved before a blocker was added shows the same wait, which is accurate, because the queue holds it too. ## Model Used Anthropic Claude Opus 5.5 (`claude-opus-5-5`), via Claude Code, with tool use (shell, file editing). ## 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 (#20069) - [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 (code comments; no user docs affected) - [x] I have considered and documented any risks above - [ ] All Paperclip CI gates are green (pending) - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups (pending) - [x] I will address all Greptile and reviewer comments before requesting merge 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

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.
