Status update: this PR is now ready for review and targets At the latest checked head The author has added fixes and validation evidence since our initial review; the earlier validation checklist should not be treated as an evaluation of this new head. Once CodeRabbit approves, reassess the latest code and evidence before requesting Fable's merge agreement. All branches are preserved. Status recorded by Codex (GPT-6); no evaluation or Fable approval of this new head is claimed. |

Inline comments:
In `@apps/desktop/scripts/neovim-terminal/transport.mjs`:
- Around line 228-242: Update the executable discovery logic around the
candidates loop to track whether each candidate is the configured override, and
when NodeFSP.access fails for that override, raise a distinct override-specific
error instead of continuing to the generic PATH-not-found error. Preserve normal
PATH discovery behavior for non-override candidates and retain the existing
validation for executable version.
In `@apps/desktop/src/editors/terminalEditorRuntime.test.ts`:
- Around line 135-140: Guard the test identified by “reads framed discovery
despite banners and distinguishes a missing binary” so it is skipped on Windows
before invoking run with the literal /bin/bash path. Preserve the existing
behavior and assertions on non-Windows platforms.
In `@apps/desktop/src/editors/terminalEditorRuntime.ts`:
- Around line 90-100: Update the preferences-loading flow in settings() so
invalid JSON or schema content resolves to the default terminal preferences,
allowing save() to replace the file. For non-ENOENT filesystem errors, clear the
cached this.preferences promise before rethrowing the original error; continue
treating only ENOENT as a missing file and preserve successful reads.
In `@apps/desktop/src/editors/terminalProbe.ts`:
- Around line 24-25: Update probePosixRoute() to use route.node as node_path
when it is available, while retaining command -v node as the fallback. Ensure
the generated probe validates and launches with the same Node executable
selected for WSL routes.
In `@apps/web/src/components/settings/EditorsSettings.tsx`:
- Line 138: Update the terminal options in the select controlled by terminal so
the current non-"automatic" terminal value is included when it is absent from
capability.terminals, including the empty-list case. Preserve the existing
Automatic option and avoid adding duplicates, ensuring the displayed selection
matches the value submitted by setTerminalEditorSettings.
In `@apps/web/src/terminalEditors.ts`:
- Around line 116-126: Memoize the value returned by useTerminalEditor,
including its rescan callback, so unchanged terminal editor state preserves
object and function identity across renders. Hoist the disconnected capability
outside the render-dependent path and use stable dependencies for refresh,
invalidateTerminalEditors, and the returned fields to prevent unnecessary
ChatMarkdown markdown-subtree work.
In `@docs/user/terminal.md`:
- Around line 30-31: Update the terminal documentation near the external
terminal launching note to include older desktop shells alongside browser and
mobile clients, stating that they retain the existing GUI editor options while
lacking the new terminal bridge capability.
In `@packages/client-runtime/src/editorChoice.ts`:
- Around line 49-52: Update the path handling around the separator index in
editorWorkspace so separator-free relative targets return "." when index is less
than zero, before slicing normalized. Preserve the existing root and
drive-letter handling for paths containing separators.

Addressed all eight inline findings in b65f207 and renamed the read-only legacy resolver as suggested. Validation: 23 focused tests passed; desktop and web typechecks passed; targeted lint passed. The generic docstring-percentage warning does not match this repository’s AGENTS.md documentation guidance. I retained comments explaining behavior and constraints rather than adding redundant descriptions solely to reach a percentage. @coderabbitai review |

I found no remaining blocking issue. The route-selected Node runtime handling is correct. The preference recovery and configured-executable failure paths are covered by focused tests. I also found no whitespace errors in the reviewed diff. The sandbox did not execute repository tests. This review uses the reported validation evidence and static inspection.

Fable's second review confirmed the earlier fixes and found a product integration blocker: terminal-editor routing read the legacy saved-environments registry instead of the current connection catalog. Fixed in
File preview intentionally exposes the same editor dispatch used by other file actions for secondary local environments; this expands the preview entry point without introducing a new server execution capability. Validation: 31 focused tests passed, desktop/web typechecks passed, targeted lint passed. Fable is reviewing the new head. These results supersede earlier code findings only where fixed; no independent GO or merge authorization is claimed yet. |

Opening an editor currently supports GUI launches and remote editor links, which cannot host an interactive Neovim session. This adds Neovim (Terminal) to Open and Settings → Editors, opening a separate Windows Terminal window in the project's native, WSL or saved SSH environment.
Desktop main owns discovery, executable overrides, account/runner validation, cached capability checks and deduplicated launch acceptance. WSL routes bind the concrete distro and account; SSH retains the saved native/WSL credential context. A packaged helper stages private payloads separately from interactive stdin, preserves workspace and file positions, cleans consumed payloads, and holds failures visible.
Header, keyboard, markdown, terminal links, diffs, changed files, file preview and Settings editor actions share the same environment preference and dispatch. The existing GUI server RPC remains compatible. Browser/older-desktop clients retain GUI behavior and explain the capability limit for a saved Neovim choice. Provider adapters are unaffected; native Linux terminal adapters remain a follow-up.
Dependency #2 has merged. This PR now targets
rtvision.Validation:
Real Windows validation found redirected console input in the terminal helper. The helper now waits on the packaged runtime without competing for input and opens the Windows console input device for interactive children; staging input remains separate.
The real workstation SSH alias passed through Debian WSL with interactive encrypted-key authentication. The packaged helper opened Neovim v0.12.2 with the normal user configuration on the intended temporary file. After the user typed a test line, Windows accessibility inspection confirmed the text in the buffer, the modified flag and NORMAL mode. Closing and relaunching the editor passed too.
Remaining validation coverage: Windows transport checks used manual packaged-helper route tests plus an actual GUI capability probe. Full GUI-driven WSL/SSH setup, ProxyJump and distro/default-account transitions remain unverified. Native Windows SSH could not authenticate to this workstation with its currently configured key; its launcher path was validated against the disposable SSH target. Native Windows Neovim is not installed on the test host. The remaining procedure is in
docs/operations/neovim-terminal-validation.md.Review follow-up fixes preserve legacy WSL SSH connections, resolve editor routes from the current connection catalog, validate the selected WSL Node runtime, and make terminal discovery action-driven. Editor preferences share cached snapshots and browser listeners. The latest 31 focused tests, desktop/web typechecks and targeted lint passed.
All five low-severity Fable follow-ups are addressed: symlinked helper entry points, duplicate version probing, consistent header access, shorter unavailable-capability caching, and duplicate preference writes. Subsequent CodeRabbit fixes cover remote markdown actions, WSL account discovery and redundant home checks, interrupted editor commands, stable editor-choice identity, and missing-file cursor fallback. The final follow-up suite passed 137 focused tests; desktop/web typechecks and targeted lint passed.
Fable 5.1 returned GO on
93bb49627. Its rerun covering later follow-ups reached the session limit, so no newer Fable verdict is claimed. Completed Fable verdict. CodeRabbit reviewed the final headf4ea60486, withdrew its remaining finding after confirming the intended saved-choice behavior, and its status check is successful.Model: GPT-6. Harness: Codex.
