Task 01: Render Model-only Agent Tab Titles

Acceptance

• An unnamed agent tab resolves to the authoritative current model display name without appending session mode or non-model ACP config values.
• A live model switch and task-detail reload retain the model-only title.
• A user-supplied session name still overrides every derived title, and task-chat/profile model selector summaries remain unchanged.

Verification

cd apps && rtk pnpm --filter @kandev/web test -- --run components/task/session-tab-title.test.ts
cd apps/web && rtk pnpm e2e:run tests/chat/model-selector-error.spec.ts -- --grep "agent tab keeps the selected model title after reload"

None.

Parallelism

sequential. The resolver, its unit contract, and the existing persistence E2E form one focused behavioral change.

Inputs

• Spec What and unnamed-agent-tab Scenario.
• PR #2021 and its resolveSessionTabTitle precedence and reload regression.
• Existing SessionPage.sessionTabBySessionId stable E2E locator.
• TaskLayout mobile/tablet branching, which confirms this Dockview tab has no mobile surface.

TDD Sequence

1. Change the non-model-config unit case to require the exact model-only label and run the focused Vitest command to confirm RED.
2. Remove non-model config composition from the derived model title without changing title precedence or selector code, then rerun Vitest to GREEN.
3. Tighten the existing model-switch persistence E2E to require the exact tab label before and after reload, then run the managed focused E2E against freshly built assets.
4. Mark this task done, mark the plan checkbox complete, and return the spec to shipped.

Risks

• Model display names can come from either the model list or the live model config option; removing the extra values must not bypass the provider-supplied model label.
• Dockview restoration can reapply stale panel titles; the existing session-tab component sync and reload E2E must continue proving the rendered tab wins.

Output Contract

Report the expected RED assertion, resolver change, exact unit and E2E command results, files changed, mobile no-surface confirmation, remaining risks, and task/plan/spec status updates.
