There was a problem hiding this comment.
The new test assigns the second value returned by gin.CreateTestContext to _ without handling it or explaining why it is safe to ignore. This violates the repository directive that returned errors must be handled or explicitly justified, including in tests. The requirement must be satisfied before merging.

🟢 Approval recommended
As mudanças são coesas, têm testes cobrindo o ajuste do stream e parecem alinhar o harness/testes ao comportamento real sem introduzir regressões evidentes.
Pull request overview
Este PR busca restaurar a estabilidade dos contratos E2E (web + runtime) e um teste específico do runtime de terminal no Windows, alinhando o harness e as asserções com o comportamento real do daemon e do stream de transcript.
Changes:
- Alinha o daemon de integração de testes ao daemon de produção ao expor o ProfileService via UDS e ao usar o checker de disponibilidade de perfil no resolver de workspace.
- Corrige a ordem de término do transcript push stream para encerrar apenas ao consumir o evento persistido
session_stopped, evitando fechar o stream antes de drenar marcadores já persistidos. - Desambigua seletores e sincronização em E2E web do terminal (múltiplas janelas por terminal; tomada de controle baseada na resolução do lease), e ajusta o teste Windows ConPTY para permitir o contrato de input oculto.
File summaries
| File | Description |
|---|---|
| web/e2e/tests/terminal.spec.ts | Torna takeTerminalControl robusto ao esperar o lease estabilizar antes de decidir clicar em “Take control”. |
| web/e2e/tests/terminal-agent.spec.ts | Endereça janelas de terminal por data-instance-key para eliminar ambiguidade quando há múltiplas janelas de terminal. |
| internal/terminal/pty/pty_windows_test.go | Ajusta invocação do PowerShell para permitir Read-Host -AsSecureString funcionar como esperado no ConPTY. |
| internal/cli/cli_integration_test.go | Passa a compor o daemon de integração com Profile Manager e o expõe via udsapi.WithProfileService. |
| internal/api/core/session_stream_transcript.go | Evita encerrar o push stream apenas por StateStopped; encerra ao consumir o evento session_stopped. |
| internal/api/core/session_stream_internal_test.go | Adiciona teste que garante drenagem de eventos persistidos antes do encerramento por session_stopped. |

What & why
Two things ride together here, because the second could not be proven green without the first. A third, smaller repair (the scaffold's release-version check) was surfaced by this PR's own CI run.
1. CI repairs.
mainhas not had a green CI run since 2026-08-25, and every failure below reproduces from exactmain(b7667d8f7c1c70eb6c943b757fd7771f746683c5). Two harness compositions and three tests are brought back in line with the runtime; no product behavior changes.TestRemoteGatewayE2EProfileWorkSurvivesDisconnectAndReconnect—profile service is unavailablesession newfailed before the scenario started (deterministic since #527).udsapi.WithProfileServiceinto the integration daemon, matching the production composition.session_stoppedwhile processing an earlier wake as soon as session state flipped to stopped, closing the stream before the already-persisted marker wake was drained.session_stoppedevent, so the marker precedes closure.E2E-020profile switches[data-app="terminal"]locator resolved to both surfaces.data-instance-key) and reads the aggregate journal from the default profile's window, which the "All profiles" lens keeps on screen.E2E-002reload and reattachtakeTerminalControlreaddata-readonlybefore the attachment'sOWNERframe named the lease, then waited for a "Take control" button that never appears once this browser turns out to hold control.extension buildof the scaffold)git describe --alwayson a shallow, tagless checkout, so its version is the short merge hash.

Fence terminal generation outputs (moved here from #540, which is closed in its favor). A same-epoch generation snapshot could overwrite a terminal output with five valid non-terminal states that were missing from the SQL fence. This follows up merged #536 and addresses the remaining review thread.

No public CLI, HTTP/UDS route, configuration, or documentation contract changes. Production changes: integration-daemon composition, transcript-stream terminal ordering, and a strengthened existing SQLite write fence. No user-visible change, so no QA scenario is flagged.
Compozy Impact Audit:
compozy__terminal_*descriptors, schemas, and capability gates are untouched; only their browser E2E assertions changed.loop_run_id/generation/node_id/item_indexrow identity and adds no datum or scope; the profile service enters the test daemon through the sameWithProfileServicecomposition the production daemon uses (internal/daemon/server_options.go).skills/compozy/describes no behavior changed here.Still red for reasons outside this PR: the implement-tasks orchestrated journey occasionally exceeds its 90s test budget on loaded runners, and two terminal journeys from #490 fail intermittently on unchanged code:
