Summary

• Hide native Windows consoles at Codex, Workbench Git, Workstream Git/worktree, and static-preview process launch boundaries.
• Keep Codex runs blocked when all completed tool executions failed, while preserving no-tool chat and successful recovery.
• Fix Windows preview-store durability: flush the copied backup through a non-truncating read/write handle.
• Add process-backed regressions and a Windows-flush-semantics persistence regression.

Verification and readiness

• 87/87 focused tests across eight files pass.
• Local-server TypeScript build, root TypeScript, scoped lint/format and diff checks pass.
• Native Windows Node24.18.0 reproduced EPERM/fsync before correction; corrected native static preview passed HTTP200/exact content/durable state/owned shutdown.
• Aaron accepted native Codex0.163.0-alpha.5 coding completion, movement, no coding/Git flashing, homepage after reload/repository load, and no preview Node window.
• Running operator test and saved state retained. No scripted product-navigation journeys added/run.

Boundaries

• This does not upgrade/install Codex globally or bundle the isolated Codex candidate.
• Other-PC reports and installer/install-over acceptance are separate from this host's native portable-app acceptance.
• Merge authorized only after exact-head CI/readiness green; merged-main CI must pass separately before installer-candidate workflow.
• No release/tag/npm publication or website download activation authorized here.
