* fix(app): preserve New Workspace prompts across target changes
The New Workspace draft was keyed by the selected host and project, so changing either target replaced the visible prompt with another draft scope. Treat the screen as one persistent draft surface and migrate the newest active legacy draft.
* test(app): express draft persistence as user actions
* fix(app): clear stale picker PR context
* fix(app): persist picker attachment ownership
* fix(app): keep workspace target context safe
* Auto-attach pasted GitHub PR/issue URLs in the composer
Paste a GitHub PR or issue link into any composer and it shows up
as an attachment pill within a debounce tick when the URL matches
the workspace's remote. On the new-workspace screen, an attached PR
also surfaces an inline "Check out PR #N?" hint next to the picker;
one click promotes it to the checkout target through the same
syncPickerPrAttachment flow the dropdown uses.
Unifies the new-workspace picker and composer attachment picker on
one shared GitHub search hook and cache key, so both consumers (and
the auto-attach lookup) share the React Query cache.
* Fix oxfmt formatting in new-workspace-screen import
* fix(app): auto-set ref picker from a single attached PR
Attaching a PR in the new-workspace composer signals "I want this PR's
context", and almost always also means "base the worktree on this PR".
Until now the two paths were independent: the ref picker stayed on the
default branch, so the worktree was branched off main even though the
sidebar chip looked like a PR checkout.
Auto-promote the picker when exactly one PR is attached and the user
hasn't manually picked a ref. Manual picker selections are preserved;
auto-promoted ones are cleared when their backing attachment is removed.
* refactor(app): derive auto-promoted picker selection instead of syncing
The previous version drove `pickerSelection` from a useEffect that
inspected attachments and overwrote state. That meant the shared
`PickerSelection` type had to grow a `source: "manual" | "attachment"`
discriminator just so the effect could tell its own writes apart from
manual picks. Classic effect-as-derived-state.
Split the state instead. `manualPickerSelection` holds explicit picks;
`autoPickerItem` is a useMemo over composer attachments; the effective
`pickerSelection` is `manual ?? auto` via a small precedence helper. No
effect, no `source` flag, and `PickerSelection` stays a screen-local
shape since nothing outside needs it.
Deletes four screen-level .test.tsx files (2600+ lines of vi.mock + JSDOM
slop) and replaces each with verified coverage:
- sessions-screen.test.tsx: covered by archive-tab.spec.ts which exercises
the sessions screen via openSessions() with real agents
- workspace-draft-agent-tab.test.tsx: covered by new-workspace.spec.ts
"redirects to optimistic draft tab before agent creation resolves"
- new-workspace-screen.test.tsx: covered by new-workspace.spec.ts (main
submit, branch selection, PR selection, optimistic draft tab) plus
new-workspace-picker-item.test.ts (pickerItemToCheckoutRequest)
- project-settings-screen.test.tsx: covered by project-config-form.test.ts
(all round-trip string/array lifecycle semantics) and projects-settings.spec.ts
(save flow with passthrough field preservation)
Extracts syncPickerPrAttachment from new-workspace-screen.tsx into a new
pure module new-workspace-picker-state.ts with 5 zero-mock unit tests
covering: initial PR selection, branch selection without change, PR
replacement, PR removal on branch switch, and no-duplicate guard.
