Pin password badge actions to their source runtime

[teamleaderleo]

Follow-up to #14867 and #14905 (password input indicator).

• Runtime guard: the GHOSTTY_ACTION_SECURE_INPUT handler only checked the TerminalSurface model, which outlives hibernation and stale-runtime release. An ON action queued by a released runtime could re-show the badge after terminalSurfaceRuntimeDidRelease() cleared it. The main-thread hop now also requires the model's current runtime surface to be the one the action came from.
• Docs parity: the local-prompt, live-apply, and pasted-text notes from all-keys.md are now in the cmux.schema.json descriptions (embedded schema regenerated) and in the Settings subtitles in all 9 locales.
• Release notification: the pane host is notified of a runtime release only when a runtime was actually released.

Summary by cubic

Fixes a race where a password badge ON action queued by a released runtime could re-show the badge after teardown cleared it. The main-thread hop now only runs if the action's callback context is still the terminal's active runtime context.

• Compares the per-runtime callback context (captured weakly) rather than the native surface pointer, which a replacement runtime may reuse.
• Adds local-prompt and pasted-text notes to the schema descriptions and Settings subtitles in all 9 locales, noting changes apply to already-open prompts.
• Notifies the pane host of a runtime release only when a runtime was actually released.

^{Written for commit ed06407. Summary will update on new commits.}

Summary by CodeRabbit

• Updates

  • Clarified that password-prompt detection applies to local prompts, including an SSH client’s own password prompt, but not sudo prompts inside an SSH session.
  • Clarified that password dots count typed characters, not pasted text, and that only the count—not the characters—is retained.
  • Changes to the password indicator setting now apply to prompts that are already open.

• Bug Fixes

  • Improved password-indicator updates when a terminal surface changes, preventing updates from being applied to a surface that is no longer current.

📝 Walkthrough

Walkthrough

Password-input descriptions clarify which prompts are detected and whether pasted text counts toward badge dots. Runtime callbacks check their source surface before updating the indicator. Teardown and hibernation notify the pane host of a release only when a runtime surface exists.

Changes

Terminal input lifecycle

Layer / File(s)	Summary
Password-input badge rules Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Navigation/CuratedSettingEntry+Default.swift, Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Sections/TerminalSection.swift, Resources/Localizable.xcstrings, web/data/cmux.schema.json	Descriptions specify that local prompts are detected, including SSH password prompts but not sudo inside an SSH session. They also state that pasted text is not counted.
Secure-input runtime guard Sources/GhosttyTerminalView.swift	The queued indicator update checks that the view still owns the same model and that the model still references the callback’s runtime surface.
Runtime release notifications Packages/macOS/CmuxTerminal/Sources/CmuxTerminal/Surface/TerminalSurface+RuntimeLifecycle.swift, Packages/macOS/CmuxTerminal/Tests/CmuxTerminalTests/TerminalSurfaceTeardownCallbackLifetimeTests.swift	Teardown and hibernation notify the pane host of runtime release only when a runtime surface exists. A test checks teardown without an installed surface.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 882c1

The change is mergeable with awareness of a narrow remaining risk: if a runtime address is reused before a queued callback runs, the password badge could briefly reappear.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 882c1

The runtime checks appear to reduce the chance that a released terminal can restore a misleading password badge. No new credential access or broader exposure was identified, though coverage is not complete.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The examined runtime change affects the password badge in the associated terminal view. The changed handler and release paths show no new credential-reading sink or privilege transition.

Trust Boundaries and Controls

• observed — The queued callback must still belong to the view’s model and to that model’s current runtime before it can change the badge. Release clears the model’s runtime reference before notifying the pane host to clear the badge.

Full details: Docstring Coverage

Explanation

Docstring coverage is 66.67% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 6 functions across 4 files. (3 skipped: 2 unsupported, 1 too large.)

Full details: Cmux Full Internationalization

Explanation

The Swift changes use String(localized:defaultValue:), and both changed catalog keys have translated entries for all 9 locales in Resources/Localizable.xcstrings. However, the PR changes user-facing web schema descriptions in web/data/cmux.schema.json without adding locale-specific entries. The localized configuration page renders property.description directly when descriptionKey is absent, so the changed English descriptions appear on localized /[locale]/docs/configuration pages. No web/messages/*.json files changed, and the two password properties have no matching schemaDescriptions entries.

Resolution

Add descriptionKey values for both password properties and add matching, non-English placeholder-free translations under docs.configuration.schemaDescriptions in every locale listed by web/i18n/routing.ts: en, ja, zh-CN, zh-TW, ko, de, es, fr, it, da, pl, ru, bs, ar, no, pt-BR, th, tr, km, and uk. Ensure the configuration page reads both descriptions through those locale-specific message entries.

Automatic catch-up: main is green again and this branch needed it.

I tried to catch this branch up with main (c9a6a0e34564), but these files need a person:

• Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Navigation/CuratedSettingEntry+Default.swift: not a generated file; needs a person
• Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Sections/TerminalSection.swift: not a generated file; needs a person
• Resources/Localizable.xcstrings: same key changed on both sides: strings.settings.terminal.showPasswordInputIndicator.subtitleOn, strings.settings.terminal.showPasswordInputDots.subtitleOn

Nothing was pushed. Merge main locally, fix those, and push; /catch-up is there again whenever you want it.

Automatic catch-up will not try this head again; a new push or /catch-up does.

Dogfood build of ed06407abe7b006ce25d4724bab2574119a843f7

cmux DEV pr-14921-ed06407a.app

The link opens this exact commit in the cmux dev menu bar app. The build starts on each push and the page waits until it is ready; a newer push replaces it. It signs in against production, so Cloud or backend changes still need a tagged build with a development backend.
