## Thinking Path > - Paperclip manages AI agents and their work. > - Isolated workspaces must resolve a starting Git ref before an agent starts. > - A task can explicitly select a branch that the repository does not have. > - The current recovery notice calls this a missing secret and offers no branch repair. > - This pull request explains the branch failure and adds a task-scoped repair action. > - Operators can correct the branch and request a guarded retry from the task thread. ## Linked Issues or Issue Description Related: Refs #11892 added unresolved-ref recovery. Refs #15719 added bounded failure diagnostics. This change uses that recovery path and adds its operator repair UI. **What happened?** A task that selects `main` in a repository with only `master` stops before the adapter starts. The task shows a missing-secret message and a generic retry. Repeating the run cannot fix the stored branch setting. **Expected behavior** Explain that the starting ref could not be resolved. Offer a verified repository default, or let the operator enter a branch. Save only the task's starting branch and retry its recorded owner through the existing admission gates. **Steps to reproduce** 1. Create an isolated-workspace task in a repository with `master` and no `main`. 2. Set the task's base ref to `main` and assign an agent. 3. Wait for the configuration failure. 4. Use the inline branch repair and confirm the agent completes in a worktree based on `master`. ## What Changed - Replace the missing-secret diagnosis for unresolved workspace refs. Keep uncertain fetch/access failures described as uncertain. - Read the remote's advertised default branch with the existing Git credentials and a bounded timeout. Do not guess or silently change the branch. - Add an atomic branch repair to the existing recovery resolution endpoint. Check company access, board runtime permission, incident identity, current owner, task/project state, dependencies, interactions, approvals, budget, and active execution before requesting a retry. - Preserve the effective inherited workspace setup when saving the task branch override, and attach one repair notice per failed run even when the incident is reused. - Bind the shared repair card to the exact recovery notice and failed run in both task-thread renderers. Validate branch syntax and prevent duplicate submissions. - Add Storybook examples, regression tests, and a documented local acceptance fixture with a real Git repository and process adapter. ## Verification - Red/green regressions cover the repair endpoint and preservation of inherited agent setup. The regression failed before each fix and passed afterward. - Focused integration suite: 162 tests passed; task-thread/card suite: 230 passed. After review refinements, all 13 repair-route tests, 10 card tests, 77 recovery-action tests, and the repeated-failure heartbeat regression passed locally. - Real browser acceptance passed for suggested-branch and custom-entry repairs. Invalid syntax left the task blocked. Both valid repairs ran the authenticated worker in a real isolated worktree and reached Done; reload preserved the result. - Repeated failures reused the recovery incident and retained an actionable notice on the latest run. The inherited-setup journey verified the provisioned file, agent branch template, worktree parent directory, and actual Git commit before completing. [Before/after screenshots](https://github.com/paperclipai/paperclip/pull/15726#issuecomment-6088734666). - Full local typecheck and build passed; server typecheck passed again after review fixes. Token gates passed. - The monolithic local Vitest run was stopped after resource-contention timeouts and stale assertions. Targeted regressions were rerun; the full CI matrix passed on final revision `26c543ff490bec29ddc77a49ee532c7f84fb96dc`. One signoff E2E worker-cancellation failure passed on a rerun without code changes. The two opt-in Storybook workflow jobs were skipped; the Storybook journey was checked manually. - Repeat the live journey with `tests/e2e/workspace-base-ref/README.md`. Storybook examples use simulated callbacks and are not the live acceptance proof. ## Risks - Default-branch discovery can add up to 10 seconds to an unresolved-ref failure. Lookup failure leaves manual entry available. - A valid branch name can still be absent or inaccessible. The retried workspace preparation remains authoritative and can block again with new evidence. - Retry remains subject to normal admission gates. The repair changes only the task override; it does not alter project or agent defaults. - No database migration or new dependency. ## Model Used OpenAI GPT-6 through Codex, with tool execution, repository analysis, and browser testing.

Workspace starting-branch repair acceptance
This fixture uses a real Git repository with a master branch and no main
branch. It runs a deterministic process adapter, with no external model calls.
Use a disposable local-trusted instance. The seed changes that instance's
experimental workspace and task-interface flags and creates a test company.
- Start a disposable Paperclip instance from this checkout. Set a separate
PAPERCLIP_HOMEand port. Keep it bound to loopback inlocal_trustedmode. - Run
node tests/e2e/workspace-base-ref/seed.mjs http://127.0.0.1:PORT. - Open the returned issue in the browser. Wait for it to become blocked.
- Confirm the thread says the starting branch is unavailable and shows the branch repair card. It must not claim that secrets are missing or offer a generic retry of the same broken setting.
- Click Use master & retry. The task must reach Done. Its agent comment
must report that it ran in an isolated worktree at the
origin/mastercommit. - Reload. Confirm the task remains Done, its task-specific base ref is
master, and its recovery action is resolved. There should be exactly two runs: the initial configuration failure and a successful process run.
To test custom input, seed another company and task. Choose Choose another
branch. Enter bad..branch and submit: the inline error must keep the task
blocked. Change it to master and submit. Verify the same durable result.
The worker uses its authenticated run API to obtain its actual workspace and mark its own task complete. It checks both the fixture file and the Git commit before doing so. A saved setting or simulated Storybook success alone does not satisfy this acceptance check.
The component stories are under Workspace branch recovery. Their save and retry callbacks are simulated; use this fixture for the real server journey.
Pass --agent-defaults to the seed command to put the missing base branch,
setup command, branch template, and worktree directory in agent defaults.
The task has no strategy override. On repair, the worker also verifies that
inherited setup ran and the branch template and worktree directory survived.
