Summary

• Fixes orca terminal close for restored live PTYs whose renderer tab no longer exists in persisted session state.
• Falls back to closing only the addressed PTY when the durable close reports the exact tab_not_found error; every other error still surfaces.
• Adds regression coverage for the ghost-terminal state observed in packaged Orca.

Testing

• pnpm lint (targeted oxfmt --check, oxlint, and changed-code quality gate passed)
• pnpm typecheck
• pnpm test (targeted runtime/shared/CLI tests passed: 13 tests)
• pnpm build
• Added or updated high-quality tests that would catch regressions, or explained why tests were not needed

Post-rebase verification:

• Runtime close cluster: 5 passed
• Shared/CLI close coverage: 8 passed
• Node TypeScript check passed
• Formatting, lint, diff check, and changed-code quality gate passed

AI Review Report

Reviewed the rebased diff against origin/main. The review checked exact-handle behavior, split-pane safety, durable-session/renderer-graph divergence, error narrowing, and agent-team cleanup. Only the literal tab_not_found condition takes the PTY fallback; other failures are rethrown. The fallback delegates to the existing handle-scoped close path, so sibling panes are not selected for termination.

Cross-platform compatibility was checked for macOS, Linux, and Windows. This change is confined to Electron main-runtime state handling and uses the existing PTY controller abstraction; it adds no shortcuts, labels, paths, shell behavior, or platform-specific branches.

Security Audit

No new IPC surface, command execution, path handling, authentication, secret handling, or dependency was introduced. Existing RPC authorization and terminal-handle resolution remain in place. The catch is intentionally exact so unrelated runtime or persistence failures are not hidden.

Notes

The fault was reproduced against packaged Orca 1.4.173 and 1.4.174-rc.0. Inspection of the 1.4.175 source found the same affected path. No installed application bundle was hotpatched.

Closing this submitted branch as the same missing-persisted-tab behavior is already represented by canonical PR #12922, which remains the owner implementation path. We will not merge this duplicate branch; the diagnosis and contribution remain credited to @jarbas-marco. No action is requested from you. Thank you.
