Problem

A native Claude Code install whose settings set "autoUpdatesChannel": "stable" was always compared against npm's latest dist-tag. claude update follows the stable channel, finds nothing newer, and exits 0, so Update now always ended with "Update command completed, but T3 Code still detects an outdated provider version." and the update badge never went away.

Reproduced on main 2a73827 with the official native installer (Claude Code 2.1.308 in a scratch HOME, ~/.claude/settings.json = {"autoUpdatesChannel":"stable"}) while npm's dist-tags were stable: 2.1.308, latest: 2.1.312. Settings → Providers offered a Claude update; every Update now printed the error above and installed nothing. Switching the setting to "latest" made the same button install 2.1.312.

Change

For the native claude update path only, the Claude driver now reads the channel claude update itself follows each time maintenance resolves:

• managed settings first (managed-settings.json, then managed-settings.d/*.json in name order, last value wins), then the user settings.json in the server's Claude config dir ($CLAUDE_CONFIG_DIR or ~/.claude; the updater runs with the server's env, not the instance's homePath);
• "stable" → the native capabilities get a lookupLatestVersion that reads npm's stable dist-tag, with latestVersion: null (Homebrew's pattern), so a failed stable lookup reports "unknown" instead of falling back to latest;
• anything else (missing, invalid, "latest") → exactly main's behaviour.

Because the channel is read at resolve time, a manual refresh or an update picks up a channel switch, and the installer-key cache only ever holds stable answers. Provider-core gains an optional nativeUpdate.lookupLatestVersion and a dist-tag argument on fetchNpmLatestVersion; npm, pnpm, bun, Homebrew and other installs are untouched.

Scope and approval

Fixes #26400

Triaged via the automated issue flow.

Verification

Focused tests (vp test run):

• apps/server/src/provider/Drivers/ClaudeDriver.test.ts (new file), 6 tests: stable channel → compared against stable (red on main: behind_latest / 2.1.312, expected current / 2.1.308); latest channel → latest; managed latest over user stable; managed drop-in overrides the base managed file; channel switch followed by a fresh resolution with the same version cache; /stable 503 → unknown, /latest never requested. Each of the last four was red on the head before its fix.
• On the merged head 3927a1d: ClaudeDriver, ClaudeHome, ProviderRegistry and maintenanceResolver tests 100/100; typecheck clean in packages/provider-core and apps/server. vp run check:changed passed format, lint and graphql, then hit a 30-minute limit on a heavily loaded VM; knip and dependent-package typechecks are left to CI.

Runtime check in the real web app (dev server with a fresh database, native Claude 2.1.308 in a scratch HOME, live npm registry with stable 2.1.308 / latest 2.1.312):

	Before (main 2a73827)	After (da17a0e)
Settings → Providers, channel stable, 1280×800, light

After-fix transcript on da17a0e: channel stable → Claude 2.1.308 with no update ("Update 1 provider", the other being Codex). Settings switched to "latest" → Refresh → Claude update offered ("Update 2 providers") → Update now installed 2.1.312, no error.

Not checked: macOS MDM and Windows registry managed policies are not read (an MDM-pinned channel that conflicts with the file-based managed settings is resolved from the files); macOS and Windows hosts were not run. No UI code changed, so no diff images.

Model and harness: Claude Opus 5.5 (lead, tests, implementation, review B) and GPT-6.1 Sol (review A) in T3 Code via Claude Code / Codex.

Walkthrough

Claude maintenance advisories now use the configured update channel to look up the matching npm version. Managed Claude settings take precedence over user settings, and tests cover channel selection and advisory results.

Changes: Claude update channel resolution

Layer / File(s)	Summary
Channel-aware npm version lookup packages/provider-core/src/server/maintenanceResolver.ts	Native update capabilities can receive an optional latest-version lookup effect. The exported npm version lookup accepts a dist-tag and defaults to latest.
Claude channel selection and coverage apps/server/src/provider/Drivers/ClaudeHome.ts, apps/server/src/provider/Drivers/ClaudeDriver.ts, apps/server/src/provider/Drivers/ClaudeDriver.test.ts	Claude reads managed settings before user settings and uses the stable npm lookup when the selected channel is stable. Tests cover channel precedence, fresh resolution after settings changes, and unavailable stable releases.

Full details: Linked Issues check

Explanation

Objective [#26400]: native Claude update checks must follow the configured channel, or avoid offering an update the native updater cannot apply. Implementation at head: (1) ClaudeDriver.ts reads autoUpdatesChannel on each maintenance resolution. Managed files are read first (managed-settings.json, then managed-settings.d/*.json sorted by name, last defined value wins). If no managed value exists, the user settings.json under the server's resolved Claude config dir is read. (2) When the channel is "stable", the resolver uses nativeUpdate.lookupLatestVersion = fetchNpmLatestVersion("@anthropic-ai/claude-code", "stable"). (3) maintenanceResolver.ts sets latestVersion to null when lookupLatestVersion is present, so a failed stable lookup yields an unknown result instead of falling back to latest. (4) Any other value, or a missing or invalid setting, uses the unchanged UPDATE resolver. The npm URL now uses the encoded dist-tag, and the default remains "latest". Automated coverage is claimed in ClaudeDriver.test.ts (6 tests: stable vs latest selection, managed precedence, drop-in override, channel switch with fresh resolution, stable 503 yields unknown without requesting /latest). I did not execute these tests. Non-coding items (manual runtime check, screenshots) are not assessed. Not read by the code path: macOS MDM and Windows registry managed policies. The issue does not require them. No unmet coding requirement found.

Full details: Out of Scope Changes check

Explanation

Changed areas at head: ClaudeDriver.ts (channel detection and stable-channel resolver for native Claude only), ClaudeHome.ts (adds the ClaudeManagedConfigDirectory context reference used to locate managed settings), maintenanceResolver.ts in provider-core (optional nativeUpdate.lookupLatestVersion and a distTag parameter on fetchNpmLatestVersion, which defaults to "latest"), and the new ClaudeDriver.test.ts. Each change supports the native Claude channel objective in [#26400]. The provider-core change is generic but inert unless lookupLatestVersion is supplied, and only the Claude driver supplies it. Non-native install paths (npm, pnpm, bun, Homebrew) keep their prior resolver. No unrelated behavior change was found in the diffs reviewed. Limit: I read the ClaudeDriver.ts and maintenanceResolver.ts diffs directly. ClaudeHome.ts and the test file were assessed from the supplied summary only.

npm's stable dist-tag doesn't match what claude update installs either, so this PR can still report a false update. The mismatch also shows up on the default latest channel, not only on stable.

claude update reads the native release bucket that https://claude.ai/install.sh uses (DOWNLOAD_BASE_URL="https://downloads.claude.ai/claude-code-releases"), not npm. At 2026-10-31 02:15 UTC:

$ curl -fsSL https://downloads.claude.ai/claude-code-releases/latest
2.1.314
$ curl -fsSL https://downloads.claude.ai/claude-code-releases/stable
2.1.308
$ npm view @anthropic-ai/claude-code dist-tags
{ stable: '2.1.309', next: '2.1.316', latest: '2.1.316' }

So both channels disagree with npm right now:

• latest: npm 2.1.316, bucket 2.1.314. With no autoUpdatesChannel set, main reports behind_latest and Update now fails with "still detects an outdated provider version". We hit this on three Linux and macOS hosts with native installs:

  $ ~/.local/bin/claude update
  Current version: 2.1.314
  Checking for updates to latest version...
  Claude Code is up to date (2.1.314)

• stable: npm 2.1.309, bucket 2.1.308. With this PR, a stable-channel install on 2.1.308 would still be offered 2.1.309, which claude update can't install.

Our fork compares native installs against downloads.claude.ai/claude-code-releases/<channel> instead, using the same nativeUpdate.lookupLatestVersion hook and latestVersion: null this PR adds. The bucket answers with a plain version string, and a failed or non-version response counts as unknown. After deploying it, all three hosts report current at 2.1.314. We don't read the managed settings, so the channel logic in this PR would still apply on top of that.
