Closes BB-59

What this changes

BB-59 reported three blocks on the Personas page. Two came from the same
place: the page demanded a saved Project Environment before it would do
anything, and an org without project-environments-enabled has no way to
create one.

  • Generate (persona and goals) gated its submit on picking a saved
    environment. With none available the button never enabled.
  • The goal form's environment picker offered "Manage environments →",
    which navigates to /environments — a route that redirects to /servers
    when the flag is off, landing the user somewhere with no next step.
  • Long persona names were clipped at the column edge.

The target is now defaulted rather than asked for, resolved through the same
ad-hoc path the swarm create flow already uses: ensureAdhocEnvironments
carries no environments gate, so it works for orgs that have Swarms but not
Environments.

Where the target comes from, most specific first:

  1. New-goal form — the target its sibling goals already use, taking the
    most common one so a stray experiment doesn't redirect everything after
    it. Archived targets are skipped.
  2. Both surfaces — the server group behind the most recently used setup
    (lastUsedAt).
  3. Fallback — most recently connected, then list order.

On the stated "most recently connected" rule: connection time alone cannot
carry it. Auto-connect stamps every server at startup in whatever order they
settle, so between two groups the newest stamp is arbitrary — the default
flipped depending on which server happened to finish connecting last. Usage
wins; connection time breaks the tie.

The column was one bug, not two. truncate sets white-space: nowrap,
which makes a line's min-content the entire string. items-start on a column
flex container then sizes it to fit-content, which can never go below
min-content. Names rendered at full width, so the ellipsis never fired and the
overflow became a horizontal scrollbar.

Readiness: local_onlyunrunnable_servers. One stdio server sinks a
run on its own — the session dies with "STDIO servers are not supported in
hosted mode" — so requiring every server to be unreachable let mixed targets
through to a guaranteed failure.

Impact

Sidebar, measured in Chromium against the same four names:

Before After
Column width 288px 320px
Horizontal overflow +360px 0
Long name 1 line, 587px inside a 172px box 2 lines, then ellipsis
Role ellipsis never fired fires
Card heights 65px 83px, all equal
Before After
New-goal form controls 6 1
Generate without a saved environment blocked works
Target chosen by the user, every time inherited or defaulted

Notes for reviewers

Generation and runs have opposite requirements. /api/web/swarm/generate/*
grounds on stored server inspections and never connects ("No
MCPClientManager" — server/routes/web/swarm-generate.ts), so a stdio server
is fine for generating. Runs do connect, and refuse it. That is why the
preflight blocks on locality but generation is unaffected by it.

Three loading guards in useSwarmDefaultTarget, each of which was a bug.
useProjectServerAttachments reports [] while loading, and
useProjectEnvironments reports undefined both while loading and when the
query is skipped. The seed latches, so choosing before either settles freezes
a wrong default permanently — and waiting on a skipped query never seeds at
all. That last one is why the usage guard is gated on usageQueryEnabled
rather than on undefined alone.

The inherited target skips the resolver, so it validates ids itself.
Nothing downstream checks an inherited target; without the live-set filter, a
goal could be created against an environment a teammate archived — the exact
case resolveComposerEnvironments raises UNRESOLVED_ENVIRONMENT for.

Sessions and turns become fixed at 1/6, matching Generate and the create
flow's default preset. The goal card shows them read-only, so this removes the
only place they could be edited — a deliberate loss, per the 8/26 addendum.
Judge and checks are not a loss: JourneyGradingEditor on the card still
edits both, including the half-written-rubric guard the form used to own.

NewJourneyForm mounts only while open. The hook it calls pulls several
queries; running them behind a closed form pulled them into every SwarmsTab
test that renders a persona.

Tests

90 across the directly affected files.

Newinherited-goal-target.test.ts (13), generate-target-recency.test.ts
(13), SwarmsTab.personaCard.test.tsx (6), and
e2e/personas-column-layout.spec.ts (8) for the geometry jsdom cannot see:
jsdom has no layout engine, so the full name sits in the DOM whether or not it
is clipped. The e2e fixture rebuilds the card from the component's own class
strings and fails loudly if those strings leave SwarmsTab.tsx.

RewrittenSwarmsTab.journeyForm.test.tsx (12),
SwarmsTab.generateEnv.test.tsx (12). Extended
cloud-server-readiness.test.ts (16), environment-picker.test.tsx (18).

RemovedSwarmsTab.envJourneyForm.test.tsx, which covered the
environment multi-select the form no longer has. Its one surviving invariant
(env submits omit serverAttachmentId) moved to journeyForm.

Verified they aren't decorative. Every fix was written test-first, and each
test was checked against the code it guards: the 6 persona-card assertions
fail against the pre-fix component; 6 of the 8 e2e geometry checks do too (the
other two are invariants that already held). The attachments-loading guard,
the usage-loading guard, the skipped-query guard, the archived-target filter,
the silent-failure catch and the inheritance branch each fail when their guard
is removed.

One pre-existing test asserted the old rule — "passes a mixed catalog, one
reachable server is enough to run" — and was changed deliberately, with an
observed session failure against exactly that shape as the evidence.

Summary by cubic

Reworks the Swarms Personas page and the swarm create/generate UX so a target is defaulted rather than asked for. Generate and the new-goal form now preselect the most recently connected server group, falling back to where that persona's goals already run most often.

Behavior changes

  • The new-goal form now only asks for goal text; target and effort follow the swarm default.
  • The generate dialog picks a server group instead of asking for environments.
  • Targets default to the most recently used server group, or that persona's most common goal target; archived targets are skipped.
  • Readiness status local_only is renamed unrunnable_servers; one stdio server blocks a run, and locality counts only when the whole set is unreachable.
  • Personas sidebar is now a fixed column with truncation; the environment picker hides the Manage link where /environments cannot render.

Written for commit e403f09. Summary will update on new commits.

Walkthrough

The pull request updates cloud server readiness states and adds runnable-server helpers. It gates the environment management link behind a feature flag. Swarm goals and generation now select server-group targets, resolve environment ids during submission, and use fixed ungraded defaults. New utilities handle target recency and sibling-goal inheritance. The Personas sidebar gains bounded text layout and geometry coverage. Tests were updated for the new flows and statuses.

Merge Risk: 🔵 Low · up to f037b

The PR changes swarm target selection and generation defaults; an existing explanation no longer matches the grounding-id resolution behavior and could mislead future maintenance. This is a bounded risk, so the change is mergeable with explicit owner follow-up.

Delete the stale grounding-id comment.

The comment states that the grounding id is resolved before the latch. It is not: target.resolve() and environmentIds[0]! now run at lines 220-221, inside the try block and after generateInFlightRef is taken. The surrounding latch discipline is correct, but this comment describes the previous implementation and would mislead the next reader of the latch invariant.

♻️ Proposed comment cleanup
     if (!targetsValid) return;
-    // Grounding id, resolved BEFORE the latch: `targetsValid` already proves
-    // latch-free side (see the comment below). Grounds on the FIRST selected
-    // environment — the backend resolves its server group, or the host's own

-
     // Every rejection that returns WITHOUT entering the try/finally below must
     // come before the latch is taken — otherwise the latch is never released
     // and the button is silently dead until the dialog is reopened.
