Split out of #159 and rebased on current main (2367505): fixes 14 and 15 of #159, unchanged in substance; where main's newer code required it, the change is adapted to it, as noted below. Small and independent; it does not depend on the other parts of #159.

Two UI messages that misled: a HOME limit row that read as the opposite of what it meant, and a plugin page error that named neither the reason nor the setting. One commit per fix.

1. HOME's model-limit rows showed a bare "9%", which read as 9% left

fix(ui): say what is used and what is left in HOME limit rows

Problem

HOME → Model limits showed the used share of a window as a large bare "9%" with a bar and the reset countdown. "Used" was only in the hover / screen-reader text. Codex's own status line shows "% left", so 9% used read as 9% left. Usage history's latest observation (the "Latest observation" value and the "No observations in this period" note) also showed a bare percent. To reproduce, spend a little of a Codex or Claude window and open HOME.

Cause

The row rendered only the number. The data is right: Codex app-server usedPercent and Claude utilization are the used share.

Fix

The row reads "9% used · 91% left" (ru «9% использовано · осталось 91%»), and so does the hover / screen-reader line. Usage history uses one helper, quotaShareText, for both of its texts. Two i18n keys (limitUsedPercent, limitLeftPercent, ru/en) and three CSS rules that keep the countdown on the right and let the share text shorten with an ellipsis in a narrow row. Nothing else on HOME changes; the Settings link that main added to rows without data is untouched.

Test

tests/quota-used-left-labels.test.mjs: Codex and Claude fixture payloads keep 9% spent as usedPercent 9; the real HOME LimitRow, rendered without Electron in ru and en, shows used and left in the row and in its hover line; usage history's templates have no bare percent left. On 2367505 without the HOME change, the four row tests fail (the visible row has no "used"/"left"); with it, all 6 pass.

2. A plugin page whose native code or module was off only got "Plugin service is not running."

fix(plugins): say when a plugin's native code or module is off, with a way to the setting

Problem

When a plugin page asked its own service and the person had not trusted the plugin's native code, or had turned off the module that runs the service, the page and the host notice only said "Plugin service is not running." (in English, also in the Russian UI). Nothing said why or where to change it. A trusted service that had crashed gave the same text without its error. To reproduce, install a plugin with a service and a page (for example examples/plugins/service-echo), leave its native code off and open the page.

Cause

PluginManager.assertService checked only that the service is in the active manifest, so every such request reached the supervisor, which knows only "not running".

Fix

• The host now refuses those requests with a fixed text: native code not trusted, or the service's module off (src/shared/pluginServiceNotice.ts). The trust check is the same one trustedServiceSpecs uses to decide which services run.
• The plugin frame shows it localized (ru/en), and the host notice carries an Open settings button that opens Settings → Agents → Extension native code (or Settings → Plugins for a module). It uses the settings destination HOME's links already use (SettingsDestination with a label): the Extension native code group gets the same data-setting-label anchor as other setting groups, so it is scrolled to and highlighted the same way. A notice with a button stays 8 s instead of 2.6 s and takes clicks only while it has one; other notices are unchanged.
• A trusted service that crashed, failed to start or waits to restart keeps the generic text, followed by its last error.

The request still fails as before; nothing is trusted or turned on by the notice.

Test

tests/plugin-service-notice.test.mjs: through the real PluginManager and PluginServiceSupervisor with the service-echo example, native code off and module off give their texts and settings sections, in ru and en; a crashed trusted service keeps the generic text with its last error and no settings notice; the toast shows the button only when it has one; the frame, App and the native-code settings group are wired to it. On 2367505 without the fix, all 5 tests fail; with it, all 5 pass.

Verification

• npm run build (includes typecheck) and npm run audit:secrets: pass.
• tests/renderer-bundle-splitting.test.mjs passes. Its own measurement of code statically reachable from App.js: 1,052,302 bytes, against 1,050,054 on main (+2,248), under its 1,100,000 budget. The added lines are what HOME and the canvas notice show, so they belong in the startup bundle; no Settings-only text is added (the native-code anchor reuses the existing pluginNativeCode label), and PluginServicesSettings stays in the lazy Settings chunk.
• Full suite (macOS arm64, throw-away HOME/XDG/CLI homes): 2,700 tests, 2,694 pass, 0 fail, 6 skipped; main is 2,689 / 2,683 / 0 / 6, and the 11 added tests are the new ones above.

Summary by CodeRabbit

• New Features
  • Plugin service errors now explain when a module is disabled or native-code trust is unavailable, and offer a shortcut to the relevant settings.
  • Usage and quota displays now show both the percentage used and the percentage remaining, with localized wording and formatting.
• Bug Fixes
  • Plugin service failures now include the recorded error when available, making unavailable-service messages more informative.

Walkthrough

The change adds plugin-service error classification, localized notices, and settings actions. It also updates HOME and usage-history displays to show used and remaining quota percentages.

Changes: Plugin service notices

Layer / File(s)	Summary
Service checks and notice definitions src/shared/pluginServiceNotice.ts, src/main/services/PluginManager.ts, src/main/services/PluginServiceSupervisor.ts, tests/plugin-service-notice.test.mjs	Service checks distinguish disabled modules and untrusted native code. Shared helpers classify and localize these notices. Supervisor rejections include a recorded last error when present. Tests cover service checks and crash errors.
Localized notices and settings actions src/renderer/src/App.tsx, src/renderer/src/components/Toast.tsx, src/renderer/src/features/plugins/PluginFrame.tsx, src/renderer/src/features/settings/PluginServicesSettings.tsx, src/renderer/src/styles/app.css, tests/plugin-service-notice.test.mjs	Recognized plugin-service errors display localized text. Actionable toasts can open the mapped settings section. Tests cover toast actions and renderer wiring.

Quota share labels

Layer / File(s)	Summary
Quota share formatting and display src/renderer/src/lib/i18n.ts, src/renderer/src/features/usage/usageText.ts, src/renderer/src/features/home/HomeZone.tsx, src/renderer/src/features/usage/UsageHistoryView.tsx, src/renderer/src/styles/app.css, tests/quota-used-left-labels.test.mjs	HOME limit rows and usage-history text display used and remaining percentages. Localized formatting clamps usage-history values to the 0–100 range. Tests cover both locales and rendered labels.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Suggested reviewers: howdeploy

Merge Risk: Low · up to 8ecec

Service notices may interrupt screen-reader speech, and compact quota widgets may clip labels. These are bounded issues with workarounds.

Security architecture risk: Minimal · up to 8ecec

The service checks become stricter, while the new settings action only opens the appropriate page and still requires explicit approval before native code can run. The review found no material security risk introduced or worsened by these changes.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — On the inspected plugin-frame path, attacker-selected service identifiers and methods remain confined to the hosting plugin. The new behavior does not provide cross-plugin service selection or additional execution authority.

Security Findings and Attack Paths

• inferred — The added failure detail can expose startup paths or process-exit information to the requesting plugin page, but it is taken from that service's record and remains behind the native-code trust gate. Its sources do not include service stderr, and no material privilege expansion was identified for a plugin already authorized to run native code.

Trust Boundaries and Controls

• observed — The new request-time trust check supplements existing execution controls: supervisor startup verifies the trusted entry hash, and the entry guard ensures that the executed entry bytes match that hash. Plugin-originated requests also remain unable to invoke the reserved host-method namespace.

Resilience and Maintainability Implications

• observed — Trust revocation clears the plugin's trust state and reconciles supervised services. Removal deletes the service from dispatch lookup, cancels restart scheduling and escalates shutdown; process exit rejects pending requests. Authorization and execution are not one atomic transition, so accepted requests may remain in flight during revocation. This lifecycle limitation predates the PR and is not an introduced concern.

Full details: Title check

Explanation

The title "fix(ui): say what HOME limits and plugin service errors mean" matches the two main changes in the changeset. HOME limit rows now show used and left percentages with localized labels. Plugin service errors now distinguish native-code-disabled and module-disabled cases, with localized text and a settings link. The title is specific and uses a conventional commit prefix. It is one sentence, under 72 characters, and free of vague terms.

Full details: Docstring Coverage

Explanation

Docstring coverage is 25.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 12 functions across 13 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Announce routine service notices politely.

When native code or a module is off, the notice has an action and receives role="alert". That role can interrupt screen-reader speech for a routine configuration notice. Use a persistent role="status" on the toast instead. (w3.org)

     </div>

Based on learnings, routine React status updates should use polite semantics such as role="status", not assertive alert semantics.

Keep quota labels visible in compact widgets.

A user can resize the limits widget to two columns. At that width, the countdown and percentage leave insufficient space for this span, and the CSS clips the used and remaining labels. The full text remains available on hover. Use a compact or wrapped layout that keeps both shares visible. (raw.githubusercontent.com)

@BIackFIame The current head 8ecec9c is blocked by Windows CI: plugin-service-notice.test.mjs:189 expects LF in its source regex, but the Windows checkout contains CRLF. Please make the assertion line-ending independent.

CodeRabbit also flagged clipped quota labels in a compact widget and the toast's announcement semantics. These affect presentation, so the owner must inspect and approve the proposed UI before this PR is merged. Please keep functional/test corrections separate from any further layout changes.

Rebase onto current main so subsequent reviews use the repository's CodeRabbit configuration.
