Note

Medium Risk
Medium risk because it changes the Windsurf provider’s data source/contract (new cloud URL + quota fields) and alters error/fallback behavior, which could break quota display if the upstream payload differs or parsing is too strict.

Overview
Updates the Windsurf plugin to only call the quota-based cloud GetUserStatus API (new server.self-serve.windsurf.com endpoint with fixed compat version), removing all local language-server probing and legacy credit parsing.

The plugin now renders Daily quota, Weekly quota, and Extra usage balance, with stricter contract validation, percent clamping, and clearer fallback hints for auth vs quota-unavailable cases.

Extensively rewrites/expands tests for the Windsurf plugin and adds targeted hook tests (useProbeAutoUpdate, useSettingsPluginActions, useAppUpdate) to cover edge cases like missing settings/order metadata, non-Tauri runtime, in-flight checks, unknown download sizes, and unmount safety.

Summary by cubic

Switched the Windsurf plugin to the quota-only cloud API and now show daily/weekly quota plus extra usage balance. Removed local LS probing and tightened auth/fallback logic with focused tests.

• Bug Fixes

  • Call exa.seat_management_pb.SeatManagementService/GetUserStatus at https://server.self-serve.windsurf.com using compat 1.108.2.
  • Prefer windsurf over windsurf-next; read the API key from both variants; detect auth statuses and show the login hint; fall through on non-2xx, network, empty, or non‑quota payloads; validate the quota contract (daily/weekly remaining%, reset times, extra balance), clamp percentages, format dollars, convert Unix seconds to ISO, and throw a clear quota‑unavailable hint when invalid.

• Refactors

  • Removed language-server discovery/probing and legacy credit parsing; updated plugins/windsurf/plugin.json to "Daily quota", "Weekly quota", and "Extra usage balance".
  • Added focused tests for the plugin and guard paths in use-probe-auto-update, use-settings-plugin-actions, and use-app-update (non‑Tauri, in‑flight rechecks, unknown download length, missing/empty order metadata, restore saved order, and unmount safety).

🤖 Augment PR Summary

Summary: Updates the Windsurf provider to use the new quota-only cloud GetUserStatus flow and removes legacy local probing/credit parsing.

Changes:

• Switches the cloud endpoint to https://server.self-serve.windsurf.com and sends a fixed compatibility version in metadata.
• Removes local language-server discovery/probing, Info.plist version reads, and legacy credit bucket parsing.
• Builds output from quota fields: daily/weekly remaining percent (rendered as % progress) plus “Extra usage balance” from overageBalanceMicros.
• Updates plugin.json line definitions to match the new quota-centric output.
• Reworks Windsurf plugin tests to cover fallthrough behavior, contract validation, clamping, and error messaging.
• Adds focused hook tests (useProbeAutoUpdate, useSettingsPluginActions, useAppUpdate) to keep coverage requirements passing.

Technical Notes: The plugin now validates a strict quota payload contract and distinguishes “no API key” (login hint) vs “quota unavailable” cases.
