fix(server): use the correct installer for provider updates

[ettoc00]

Problem

T3 could resolve a provider executable from one concrete installation while applying an update through a different installer or package-manager prefix. For example, the active executable could be owned by Scoop or by one npm prefix while the updater selected from PATH targeted another installation.

This change replaces installer guessing with installation-aware resolution for Claude, Codex, OpenCode, and Grok. T3 resolves the active executable, verifies its owning installation from installer metadata, derives the exact update command and environment, and re-resolves installation identity immediately before and after execution.

For catalog-managed providers, one-click updates are exposed only when ownership can be verified. Unknown or ambiguous installations remain manual-only. The implementation covers native installers, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet.

What changed

• adds a declarative installation catalog with shared detector, version resolver, update action, environment, cache-key, and instructions primitives
• covers native, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet installations
• proves manager ownership from the resolved executable and manager metadata before enabling one-click updates
• bounds all installer metadata reads to 64 KiB, rejects oversized or invalid UTF-8 evidence, and caches repeated reads within one resolution
• distinguishes Homebrew formulae from casks and emits cask-aware upgrade commands
• keeps unknown or ambiguous ownership manual-only; bare commands are resolved through PATH and must be proven by the installation catalog
• pins npm updates to the verified owning global prefix, even when the resolved npm executable has a different default prefix
• carries installation-specific update environments and executes the exact resolved native executable
• re-resolves installation identity immediately before and after updating to prevent stale or mismatched updates
• updates the provider-maintenance server contract for fresh per-instance resolution and adjusts Settings for per-instance progress and verified “Check for updates” actions
• avoids mixing npm latest-version checks with native updates; native latest remains unknown until an official channel resolver is available

Related issues and superseded fixes

Closes#5629
Closes#6245
Closes#7730

This supersedes the narrower fixes proposed in #5630, #6247, #7731, and #8832.

These reports expose the same underlying correctness problem in different forms:
T3 could identify one provider installation while deriving the updater, package
name, or latest-version channel from assumptions belonging to another
installation.

This PR replaces those independent heuristics with one ownership-verified
installation model. The active executable is resolved first; its owning
installer and update target must then be proven from installer metadata.
Unknown or ambiguous installations remain manual-only, and ownership is
revalidated immediately before and after an update.

Note

High Risk
Changes how provider update commands are chosen and executed; incorrect ownership logic could update the wrong install or block legitimate updates, and the lazy resolution path affects registry and settings UX.

Overview
Replaces PATH-based installer guessing with installation-aware maintenance: the server resolves the active provider binary, proves which package manager or installer owns it, and only then exposes one-click update commands (npm prefix pinning, Homebrew/Scoop/WinGet, native installers, etc.). Unverified or ambiguous installs stay manual-only.

Contract and wiring:ServerProviderShape now carries resolveMaintenance as a lazy Effect instead of a static maintenanceCapabilities. Drivers (Claude, Codex, OpenCode, Grok) use makeProviderMaintenanceResolver plus makeProviderMaintenanceCapabilitySources (cached advisory probes vs fresh resolution before updates). Provider env merges with HostProcessEnvironment; ProviderRegistry exposes resolveProviderMaintenanceCapabilitiesForInstance.

New maintenance/ stack: catalog detectors (catalogs.ts), shared types (definition.ts), ordered resolution with fail-closed manual fallback (resolver.ts), and strict semver helpers (version.ts), with broad unit coverage. Grok moves from manual-only to full package/native maintenance metadata.

Safety: bounded metadata reads, probe output limits, resolution timeouts that do not fall back to unsafe npm updates, and stricter version advisory rules (e.g. native installs without a verified latest channel).

Note

Replace package-managed maintenance resolvers with installation-aware makeProviderMaintenanceResolver

• Replaces makePackageManagedProviderMaintenanceResolver with makeProviderMaintenanceResolver across Claude, Codex, Cursor, Grok, and OpenCode drivers; definitions now use packageName, executableName, instructionsUrl, and wingetPackageId instead of npmPackageName and nested nativeUpdate.executable/lockKey.
• Introduces a new maintenance catalog/resolver subsystem in apps/server/src/provider/maintenance/ that detects installations via bounded probes, verifies ownership, resolves real executable paths, and falls back to a manual-only installation when nothing matches.
• Changes ServerProviderShape.maintenanceCapabilities from a synchronous value to an effectful resolveMaintenance: Effect<ProviderMaintenanceCapabilities>, and renames ProviderRegistry.getProviderMaintenanceCapabilitiesForInstance to resolveProviderMaintenanceCapabilitiesForInstance; all drivers, tests, and mocks are updated.
• The maintenance runner in providerMaintenanceRunner.ts now re-resolves capabilities before and after running an update, verifies identityKey and lockKey stability, requires absolute executable paths, and classifies success by version advancement via compareMaintenanceVersions.
• UI in ProviderInstanceCard.tsx and providerStatus.ts now shows a muted "Check for updates" action with a refresh icon when the advisory status is unknown but a verified updateCommand exists.
• Risk: ServerProviderShape and ProviderRegistryShape API changes break any out-of-tree implementations that read maintenanceCapabilities synchronously or call getProviderMaintenanceCapabilitiesForInstance; the runner now aborts updates if identityKey changes mid-update or if the update executable is not an absolute path.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk:🟠 High · up to 54cbe

This change routes provider updates through installer ownership checks, but the current head still has a test file that cannot compile, a Cursor update path without identity verification, and cancellation handling that can delay or bypass probe timeouts; several version and installer edge cases can also hide or misclassify updates. The PR is not merge-ready until these issues are fixed or explicitly accepted.

Map an unparsable version comparison to unknown.

compareMaintenanceVersions returns number | null; it returns null when either side does not parse. The strict === -1 check then falls through to { status: "current" }. A provider with a non-semver version string is reported as up to date instead of unknown.

Select the greatest version instead of the first regex match.

The parser takes the first semver-shaped token in the winget show --versions output. The command prints a table with a header, and the row order is not a documented contract. If the output ever lists the oldest version first, or a header field contains a version-shaped token, latestVersion becomes wrong and the update advisory misleads the user. Compare all candidates and keep the greatest one.

Confirm canonicalPath never receives relative paths.

pathApi.resolve uses process.cwd() as the base. When platform is "win32" and the host is POSIX (or the reverse), a relative input resolves against a foreign-format cwd and produces a meaningless canonical path. All current callers pass absolute paths, so this is a robustness note only. Consider returning early or normalizing without resolve when pathApi.isAbsolute(path) is false.

Add a test for the undetermined short-circuit and for the native update environment.

Two behaviors of this cohort have no coverage here:

1. resolveInstallation returns manual-only and skips the npm fallback when an owned definition reports Undetermined, even for a bare command with npm available. This branch decides whether a wrong update command can run, so it needs a focused test. A Scoop shim with an unreadable .shim file plus commands: { npm } reproduces it, and the expected label is "Unknown installation — verification failed".
2. nativeDefinition passes native.environment(executable, context.environment) into update.environment. No test asserts that the resolved installation carries that environment.

The run stub at line 54 ignores its environment argument. Capture it if you assert environment propagation.

Avoid the implicit "codex" executable-name default.

The fallback chain resolves executableName to "codex" for every provider that is not claudeAgent or opencode. All three drivers pass executableName explicitly today, so this branch only serves other providers, including future Cursor and Grok adapters and the test fixtures. A wrong executable name feeds makeProviderInstallationCatalog and can produce incorrect detection instead of a clear failure.

Make executableName required on ProviderMaintenanceDefinition, or derive it from packageName instead of a hard-coded provider name.

The coding guidelines require an explicit decision for every provider adapter: "Provider-shaped features require an explicit decision for every provider adapter: Codex, Claude, Cursor, Grok, and OpenCode, including an explicit unsupported decision where necessary."

- Around line 137-145: Cache the maintenance-capability resolution with the same
short-TTL Cache pattern used by capabilitiesProbeCache, so repeated refreshes
reuse probe results instead of re-executing the Effect. Update
resolveMaintenance in apps/server/src/provider/Drivers/ClaudeDriver.ts lines
137-145, apps/server/src/provider/Drivers/CodexDriver.ts lines 152-160, and
apps/server/src/provider/Drivers/OpenCodeDriver.ts lines 147-155 before passing
it to the provider setup and snapshot enrichment.
In `@apps/server/src/provider/maintenance/catalogs.ts`:
- Around line 422-459: Use the normalized path when slicing at the detected shim
marker: update both root derivations in detect-scoop so root and managerRoot are
sliced from observed and executablePath respectively, rather than raw
backslash-replaced paths. Keep the existing marker index calculations and
downstream path joins unchanged.
- Around line 138-171: Update the Vite+ entry in the nodeManagers array to use
documented, supported vp commands for global-root detection, latest-version
lookup, and package updates; replace the unsupported rootArgs and latestArgs
probes while preserving the existing Bun, pnpm, and npm entries.
In `@apps/server/src/provider/providerMaintenance.ts`:
- Around line 637-642: Update resolveNodePackage and
capabilitiesFromInstallation so a missing or failed manager lookup does not
preserve latestVersion as explicit null; omit the field or otherwise mark it as
unavailable. Ensure resolveLatestProviderVersion treats that unavailable result
as eligible for fetchNpmLatestVersion, while retaining authoritative
manager-provided versions.
In `@apps/server/src/provider/providerMaintenanceRunner.ts`:
- Around line 396-400: In the maintenance update flow around
runMaintenanceCommand, reject the update when freshUpdate.lockKey differs from
update.lockKey, including legacy capabilities without an identityKey. Ensure the
command is not executed under a stale lock key, while preserving execution for
matching lock keys.
- Around line 381-394: Replace the regex-based executable path validation in the
identity-verified update branch with the existing platform path service, using
Path.Path.isAbsolute (or the already imported node:path equivalent). Preserve
the failure state for relative paths while accepting valid POSIX, drive-letter,
UNC, and extended-length Windows paths.

Outside diff comments:
In `@apps/server/src/provider/providerMaintenance.ts`:
- Around line 575-584: Update the version-status logic around
compareMaintenanceVersions so a null comparison result returns { status:
"unknown", message: null } before the current-version fallback. Preserve the
behind_latest result for -1 and current result only for valid non-behind
comparisons.

Nitpick comments:
In `@apps/server/src/provider/Drivers/CodexDriver.ts`:
- Around line 63-71: Update the Codex UPDATE definition and
makeProviderMaintenanceResolver so the Codex standalone installer rule using the
/.codex/packages/standalone/releases/ path is declared through nativeUpdate in
CodexDriver.ts; remove the provider-name-specific native rule from the shared
factory while preserving other providers’ maintenance behavior.
In `@apps/server/src/provider/Drivers/OpenCodeDriver.ts`:

OpenCodeDriver.ts with a next-line suppression placed immediately before the
node:path import, leaving other diagnostics enabled.
In `@apps/server/src/provider/Layers/ProviderRegistry.ts`:
- Around line 511-513: Update getProviderMaintenanceCapabilitiesForInstance to
directly reference resolveProviderMaintenanceCapabilitiesForInstance instead of
wrapping it with another Effect.fn, preserving the deprecated alias while
avoiding an additional tracing span.
- Around line 499-509: Update resolveProviderMaintenanceCapabilitiesForInstance
to retrieve the subscription directly with the liveSubsRef map’s get(instanceId)
instead of scanning Array.from(...).find(...), while preserving the existing
resolveMaintenance and maintenanceCapabilities fallback behavior.
In `@apps/server/src/provider/maintenance/catalogs.test.ts`:
- Around line 377-394: Add focused tests in the maintenance catalog suite for
resolveInstallation to verify an owned Scoop shim with an unreadable .shim file
returns “Unknown installation — verification failed”, remains manual-only, and
skips the npm fallback even when npm is available. Add coverage for
nativeDefinition confirming the resolved installation’s update.environment
receives native.environment(executable, context.environment); capture the run
stub’s environment argument to assert propagation.
In `@apps/server/src/provider/maintenance/catalogs.ts`:
- Around line 672-675: Update the version-selection logic using
compareMaintenanceVersions imported alongside normalizeMaintenanceVersion from
./version.ts: normalize all semver candidates from show.stdout, discard invalid
values, and select the greatest version rather than the first match. Preserve
null when no valid candidates exist.
- Around line 460-476: Change the global declaration in the maintenance catalog
flow to const, since its value is not reassigned; leave the surrounding global
Scoop verification logic unchanged.
- Around line 393-394: Update the catalog detection evidence type and detect
flow to include the non-null Homebrew formula when a match is returned, then
change resolve to read formula from its evidence instead of using
input.homebrewFormula!. Preserve the existing notMatched result when the formula
is absent and keep the formula value consistent through resolve.
In `@apps/server/src/provider/maintenance/definition.ts`:
- Around line 115-119: Update canonicalPath to explicitly handle relative inputs
before calling pathApi.resolve, avoiding use of the host process.cwd() when the
requested platform differs from the host; either reject/return early or
normalize via a platform-appropriate approach, while preserving existing
canonicalization for absolute paths.
In `@apps/server/src/provider/maintenance/resolver.ts`:
- Around line 14-24: Update the resolver flow around resolveFirst and
resolveInstallation to log the aggregated reasons whenever the result is
Undetermined, before returning the generic manual-installation outcome. Include
the collected reasons in the debug or warning message, while preserving the
existing Matched and NotMatched behavior.
In `@apps/server/src/provider/providerMaintenance.ts`:
- Around line 412-418: Remove the hard-coded "codex" fallback in the
executableName resolution within ProviderMaintenanceDefinition and require each
provider adapter to make an explicit executable-name decision. Prefer making
executableName required and update all definitions, including Codex, Claude,
Cursor, Grok, OpenCode, and test fixtures, or derive it from packageName where
appropriate; preserve an explicit unsupported outcome for providers without an
executable.
In `@apps/server/src/provider/providerMaintenanceRunner.test.ts`:
- Around line 303-354: Add a focused test alongside the existing
installation-identity verification test using capabilities with no identityKey
from getProviderMaintenanceCapabilitiesForInstance and refreshed capabilities
with a different updateLockKey. Assert the changed-manager case does not proceed
to the spawn step and preserves the expected update result, while keeping the
test deterministic without timeouts.

[juliusmarminge]

Thanks for digging into this — you found the right root cause (T3 resolving one install and updating another) and the npm --prefix pinning plus Homebrew formula/cask detection were the correct fixes for #5629/#6245/#7730.

I've opened #9325 which carries those pieces (and the per-instance settings state) onto current main and closes the same three issues. I didn't push here because the branch is 61 commits behind and the changes are structural rather than a rebase. Two things I couldn't land as-is:

• Native installs (~/.local/bin/claude, standalone Codex, ~/.opencode/bin) set latestVersion: null, which drops them to unknown and removes the launch toast for the default install path. Native and npm share a version train, so fix(server): only run provider updates through the installer that owns the binary #9325 keeps the registry as the latest source there and only lets Homebrew override it.
• The Vite+ detector runs vp root -g, which isn't a vp subcommand (exit 2), so it always falls through to npm.

Scoop and WinGet support look useful but need their own issue and someone on Windows to validate; the identity hashing, wrapper-script parsing, and three-way re-resolution in the runner I simplified to a single fresh read under the lock. Happy to review a follow-up for the Windows managers if you want to split them out.

[ettoc00]

Thanks, happy to take the Scoop/WinGet follow-up and validate it on Windows!

Problem

T3 could resolve a provider executable from one concrete installation while applying an update through a different installer or package-manager prefix. For example, the active executable could be owned by Scoop or by one npm prefix while the updater selected from PATH targeted another installation.

This change replaces installer guessing with installation-aware resolution for Claude, Codex, OpenCode, and Grok. T3 resolves the active executable, verifies its owning installation from installer metadata, derives the exact update command and environment, and re-resolves installation identity immediately before and after execution.

For catalog-managed providers, one-click updates are exposed only when ownership can be verified. Unknown or ambiguous installations remain manual-only. The implementation covers native installers, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet.

What changed

• adds a declarative installation catalog with shared detector, version resolver, update action, environment, cache-key, and instructions primitives
• covers native, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet installations
• proves manager ownership from the resolved executable and manager metadata before enabling one-click updates
• bounds all installer metadata reads to 64 KiB, rejects oversized or invalid UTF-8 evidence, and caches repeated reads within one resolution
• distinguishes Homebrew formulae from casks and emits cask-aware upgrade commands
• keeps unknown or ambiguous ownership manual-only; bare commands are resolved through PATH and must be proven by the installation catalog
• pins npm updates to the verified owning global prefix, even when the resolved npm executable has a different default prefix
• carries installation-specific update environments and executes the exact resolved native executable
• re-resolves installation identity immediately before and after updating to prevent stale or mismatched updates
• updates the provider-maintenance server contract for fresh per-instance resolution and adjusts Settings for per-instance progress and verified “Check for updates” actions
• avoids mixing npm latest-version checks with native updates; native latest remains unknown until an official channel resolver is available

Related issues and superseded fixes

Closes#5629
Closes#6245
Closes#7730

This supersedes the narrower fixes proposed in #5630, #6247, #7731, and #8832.

These reports expose the same underlying correctness problem in different forms:
T3 could identify one provider installation while deriving the updater, package
name, or latest-version channel from assumptions belonging to another
installation.

This PR replaces those independent heuristics with one ownership-verified
installation model. The active executable is resolved first; its owning
installer and update target must then be proven from installer metadata.
Unknown or ambiguous installations remain manual-only, and ownership is
revalidated immediately before and after an update.

Related but intentionally out of scope: #4066, #6115, #7406, #8280, #4211,
#8247, and #8363.

Note

High Risk
Changes how provider update commands are chosen and executed; incorrect ownership logic could update the wrong install or block legitimate updates, and the lazy resolution path affects registry and settings UX.

Overview
Replaces PATH-based installer guessing with installation-aware maintenance: the server resolves the active provider binary, proves which package manager or installer owns it, and only then exposes one-click update commands (npm prefix pinning, Homebrew/Scoop/WinGet, native installers, etc.). Unverified or ambiguous installs stay manual-only.

Contract and wiring:ServerProviderShape now carries resolveMaintenance as a lazy Effect instead of a static maintenanceCapabilities. Drivers (Claude, Codex, OpenCode, Grok) use makeProviderMaintenanceResolver plus makeProviderMaintenanceCapabilitySources (cached advisory probes vs fresh resolution before updates). Provider env merges with HostProcessEnvironment; ProviderRegistry exposes resolveProviderMaintenanceCapabilitiesForInstance.

New maintenance/ stack: catalog detectors (catalogs.ts), shared types (definition.ts), ordered resolution with fail-closed manual fallback (resolver.ts), and strict semver helpers (version.ts), with broad unit coverage. Grok moves from manual-only to full package/native maintenance metadata.

Safety: bounded metadata reads, probe output limits, resolution timeouts that do not fall back to unsafe npm updates, and stricter version advisory rules (e.g. native installs without a verified latest channel).

Note

Replace package-managed maintenance resolvers with installation-aware makeProviderMaintenanceResolver

• Replaces makePackageManagedProviderMaintenanceResolver with makeProviderMaintenanceResolver across Claude, Codex, Cursor, Grok, and OpenCode drivers; definitions now use packageName, executableName, instructionsUrl, and wingetPackageId instead of npmPackageName and nested nativeUpdate.executable/lockKey.
• Introduces a new maintenance catalog/resolver subsystem in apps/server/src/provider/maintenance/ that detects installations via bounded probes, verifies ownership, resolves real executable paths, and falls back to a manual-only installation when nothing matches.
• Changes ServerProviderShape.maintenanceCapabilities from a synchronous value to an effectful resolveMaintenance: Effect<ProviderMaintenanceCapabilities>, and renames ProviderRegistry.getProviderMaintenanceCapabilitiesForInstance to resolveProviderMaintenanceCapabilitiesForInstance; all drivers, tests, and mocks are updated.
• The maintenance runner in providerMaintenanceRunner.ts now re-resolves capabilities before and after running an update, verifies identityKey and lockKey stability, requires absolute executable paths, and classifies success by version advancement via compareMaintenanceVersions.
• UI in ProviderInstanceCard.tsx and providerStatus.ts now shows a muted "Check for updates" action with a refresh icon when the advisory status is unknown but a verified updateCommand exists.
• Risk: ServerProviderShape and ProviderRegistryShape API changes break any out-of-tree implementations that read maintenanceCapabilities synchronously or call getProviderMaintenanceCapabilitiesForInstance; the runner now aborts updates if identityKey changes mid-update or if the update executable is not an absolute path.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk:🟠 High · up to 54cbe

This change routes provider updates through installer ownership checks, but the current head still has a test file that cannot compile, a Cursor update path without identity verification, and cancellation handling that can delay or bypass probe timeouts; several version and installer edge cases can also hide or misclassify updates. The PR is not merge-ready until these issues are fixed or explicitly accepted.

Map an unparsable version comparison to unknown.

Alias the resolver directly instead of wrapping it in a second Effect.fn.

resolveProviderMaintenanceCapabilitiesForInstance is already an Effect.fn. Wrapping it again adds a second tracing span for every call with no behavior change. Assign the function directly if you want the deprecated name to remain.

Select the greatest version instead of the first regex match.

The parser takes the first semver-shaped token in the winget show --versions output. The command prints a table with a header, and the row order is not a documented contract. If the output ever lists the oldest version first, or a header field contains a version-shaped token, latestVersion becomes wrong and the update advisory misleads the user. Compare all candidates and keep the greatest one.

Confirm canonicalPath never receives relative paths.

pathApi.resolve uses process.cwd() as the base. When platform is "win32" and the host is POSIX (or the reverse), a relative input resolves against a foreign-format cwd and produces a meaningless canonical path. All current callers pass absolute paths, so this is a robustness note only. Consider returning early or normalizing without resolve when pathApi.isAbsolute(path) is false.

Add a test for the undetermined short-circuit and for the native update environment.

Two behaviors of this cohort have no coverage here:

1. resolveInstallation returns manual-only and skips the npm fallback when an owned definition reports Undetermined, even for a bare command with npm available. This branch decides whether a wrong update command can run, so it needs a focused test. A Scoop shim with an unreadable .shim file plus commands: { npm } reproduces it, and the expected label is "Unknown installation — verification failed".
2. nativeDefinition passes native.environment(executable, context.environment) into update.environment. No test asserts that the resolved installation carries that environment.

The run stub at line 54 ignores its environment argument. Capture it if you assert environment propagation.

As per coding guidelines: "Backend behavior changes must include focused tests for that behavior".

Avoid the implicit "codex" executable-name default.

The fallback chain resolves executableName to "codex" for every provider that is not claudeAgent or opencode. All three drivers pass executableName explicitly today, so this branch only serves other providers, including future Cursor and Grok adapters and the test fixtures. A wrong executable name feeds makeProviderInstallationCatalog and can produce incorrect detection instead of a clear failure.

Make executableName required on ProviderMaintenanceDefinition, or derive it from packageName instead of a hard-coded provider name.

The coding guidelines require an explicit decision for every provider adapter: "Provider-shaped features require an explicit decision for every provider adapter: Codex, Claude, Cursor, Grok, and OpenCode, including an explicit unsupported decision where necessary."

Thanks for digging into this — you found the right root cause (T3 resolving one install and updating another) and the npm --prefix pinning plus Homebrew formula/cask detection were the correct fixes for #5629/#6245/#7730.

I've opened #9325 which carries those pieces (and the per-instance settings state) onto current main and closes the same three issues. I didn't push here because the branch is 61 commits behind and the changes are structural rather than a rebase. Two things I couldn't land as-is:

• Native installs (~/.local/bin/claude, standalone Codex, ~/.opencode/bin) set latestVersion: null, which drops them to unknown and removes the launch toast for the default install path. Native and npm share a version train, so fix(server): only run provider updates through the installer that owns the binary #9325 keeps the registry as the latest source there and only lets Homebrew override it.
• The Vite+ detector runs vp root -g, which isn't a vp subcommand (exit 2), so it always falls through to npm.

Scoop and WinGet support look useful but need their own issue and someone on Windows to validate; the identity hashing, wrapper-script parsing, and three-way re-resolution in the runner I simplified to a single fresh read under the lock. Happy to review a follow-up for the Windows managers if you want to split them out.

Problem

T3 could resolve a provider executable from one concrete installation while applying an update through a different installer or package-manager prefix. For example, the active executable could be owned by Scoop or by one npm prefix while the updater selected from PATH targeted another installation.

This change replaces installer guessing with installation-aware resolution for Claude, Codex, OpenCode, and Grok. T3 resolves the active executable, verifies its owning installation from installer metadata, derives the exact update command and environment, and re-resolves installation identity immediately before and after execution.

For catalog-managed providers, one-click updates are exposed only when ownership can be verified. Unknown or ambiguous installations remain manual-only. The implementation covers native installers, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet.

What changed

• adds a declarative installation catalog with shared detector, version resolver, update action, environment, cache-key, and instructions primitives
• covers native, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet installations
• proves manager ownership from the resolved executable and manager metadata before enabling one-click updates
• bounds all installer metadata reads to 64 KiB, rejects oversized or invalid UTF-8 evidence, and caches repeated reads within one resolution
• distinguishes Homebrew formulae from casks and emits cask-aware upgrade commands
• keeps unknown or ambiguous ownership manual-only; bare commands are resolved through PATH and must be proven by the installation catalog
• pins npm updates to the verified owning global prefix, even when the resolved npm executable has a different default prefix
• carries installation-specific update environments and executes the exact resolved native executable
• re-resolves installation identity immediately before and after updating to prevent stale or mismatched updates
• updates the provider-maintenance server contract for fresh per-instance resolution and adjusts Settings for per-instance progress and verified “Check for updates” actions
• avoids mixing npm latest-version checks with native updates; native latest remains unknown until an official channel resolver is available

Related issues and superseded fixes

Closes#5629
Closes#6245
Closes#7730

This supersedes the narrower fixes proposed in #5630, #6247, #7731, and #8832.

These reports expose the same underlying correctness problem in different forms:
T3 could identify one provider installation while deriving the updater, package
name, or latest-version channel from assumptions belonging to another
installation.

This PR replaces those independent heuristics with one ownership-verified
installation model. The active executable is resolved first; its owning
installer and update target must then be proven from installer metadata.
Unknown or ambiguous installations remain manual-only, and ownership is
revalidated immediately before and after an update.

Note

High Risk
Changes how provider update commands are chosen and executed; incorrect ownership logic could update the wrong install or block legitimate updates, and the lazy resolution path affects registry and settings UX.

Overview
Replaces PATH-based installer guessing with installation-aware maintenance: the server resolves the active provider binary, proves which package manager or installer owns it, and only then exposes one-click update commands (npm prefix pinning, Homebrew/Scoop/WinGet, native installers, etc.). Unverified or ambiguous installs stay manual-only.

Contract and wiring:ServerProviderShape now carries resolveMaintenance as a lazy Effect instead of a static maintenanceCapabilities. Drivers (Claude, Codex, OpenCode, Grok) use makeProviderMaintenanceResolver plus makeProviderMaintenanceCapabilitySources (cached advisory probes vs fresh resolution before updates). Provider env merges with HostProcessEnvironment; ProviderRegistry exposes resolveProviderMaintenanceCapabilitiesForInstance.

New maintenance/ stack: catalog detectors (catalogs.ts), shared types (definition.ts), ordered resolution with fail-closed manual fallback (resolver.ts), and strict semver helpers (version.ts), with broad unit coverage. Grok moves from manual-only to full package/native maintenance metadata.

Safety: bounded metadata reads, probe output limits, resolution timeouts that do not fall back to unsafe npm updates, and stricter version advisory rules (e.g. native installs without a verified latest channel).

Note

Replace package-managed maintenance resolvers with installation-aware makeProviderMaintenanceResolver

• Replaces makePackageManagedProviderMaintenanceResolver with makeProviderMaintenanceResolver across Claude, Codex, Cursor, Grok, and OpenCode drivers; definitions now use packageName, executableName, instructionsUrl, and wingetPackageId instead of npmPackageName and nested nativeUpdate.executable/lockKey.
• Introduces a new maintenance catalog/resolver subsystem in apps/server/src/provider/maintenance/ that detects installations via bounded probes, verifies ownership, resolves real executable paths, and falls back to a manual-only installation when nothing matches.
• Changes ServerProviderShape.maintenanceCapabilities from a synchronous value to an effectful resolveMaintenance: Effect<ProviderMaintenanceCapabilities>, and renames ProviderRegistry.getProviderMaintenanceCapabilitiesForInstance to resolveProviderMaintenanceCapabilitiesForInstance; all drivers, tests, and mocks are updated.
• The maintenance runner in providerMaintenanceRunner.ts now re-resolves capabilities before and after running an update, verifies identityKey and lockKey stability, requires absolute executable paths, and classifies success by version advancement via compareMaintenanceVersions.
• UI in ProviderInstanceCard.tsx and providerStatus.ts now shows a muted "Check for updates" action with a refresh icon when the advisory status is unknown but a verified updateCommand exists.
• Risk: ServerProviderShape and ProviderRegistryShape API changes break any out-of-tree implementations that read maintenanceCapabilities synchronously or call getProviderMaintenanceCapabilitiesForInstance; the runner now aborts updates if identityKey changes mid-update or if the update executable is not an absolute path.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk:🟠 High · up to 54cbe

This change routes provider updates through installer ownership checks, but the current head still has a test file that cannot compile, a Cursor update path without identity verification, and cancellation handling that can delay or bypass probe timeouts; several version and installer edge cases can also hide or misclassify updates. The PR is not merge-ready until these issues are fixed or explicitly accepted.

Map an unparsable version comparison to unknown.

Select the greatest version instead of the first regex match.

The parser takes the first semver-shaped token in the winget show --versions output. The command prints a table with a header, and the row order is not a documented contract.

Confirm canonicalPath never receives relative paths.

pathApi.resolve uses process.cwd() as the base. When platform is "win32" and the host is POSIX (or the reverse), a relative input resolves against a foreign-format cwd and produces a meaningless canonical path. All current callers pass absolute paths, so this is a robustness note only. Consider returning early or normalizing without resolve when pathApi.isAbsolute(path) is false.

Add a test for the undetermined short-circuit and for the native update environment.

Two behaviors of this cohort have no coverage here:

1. resolveInstallation returns manual-only and skips the npm fallback when an owned definition reports Undetermined, even for a bare command with npm available. This branch decides whether a wrong update command can run, so it needs a focused test. A Scoop shim with an unreadable .shim file plus commands: { npm } reproduces it, and the expected label is "Unknown installation — verification failed".
2. nativeDefinition passes native.environment(executable, context.environment) into update.environment. No test asserts that the resolved installation carries that environment.

The run stub at line 54 ignores its environment argument. Capture it if you assert environment propagation.

Avoid the implicit "codex" executable-name default.

The fallback chain resolves executableName to "codex" for every provider that is not claudeAgent or opencode. All three drivers pass executableName explicitly today, so this branch only serves other providers, including future Cursor and Grok adapters and the test fixtures. A wrong executable name feeds makeProviderInstallationCatalog and can produce incorrect detection instead of a clear failure.

Make executableName required on ProviderMaintenanceDefinition, or derive it from packageName instead of a hard-coded provider name.

[juliusmarminge]

Thanks for digging into this — you found the right root cause (T3 resolving one install and updating another) and the npm --prefix pinning plus Homebrew formula/cask detection were the correct fixes for #5629/#6245/#7730.

I've opened #9325 which carries those pieces (and the per-instance settings state) onto current main and closes the same three issues. I didn't push here because the branch is 61 commits behind and the changes are structural rather than a rebase. Two things I couldn't land as-is:

• Native installs (~/.local/bin/claude, standalone Codex, ~/.opencode/bin) set latestVersion: null, which drops them to unknown and removes the launch toast for the default install path. Native and npm share a version train, so fix(server): only run provider updates through the installer that owns the binary #9325 keeps the registry as the latest source there and only lets Homebrew override it.
• The Vite+ detector runs vp root -g, which isn't a vp subcommand (exit 2), so it always falls through to npm.

Scoop and WinGet support look useful but need their own issue and someone on Windows to validate; the identity hashing, wrapper-script parsing, and three-way re-resolution in the runner I simplified to a single fresh read under the lock. Happy to review a follow-up for the Windows managers if you want to split them out.

[ettoc00]

Thanks, happy to take the Scoop/WinGet follow-up and validate it on Windows!

Problem

T3 could resolve a provider executable from one concrete installation while applying an update through a different installer or package-manager prefix. For example, the active executable could be owned by Scoop or by one npm prefix while the updater selected from PATH targeted another installation.

This change replaces installer guessing with installation-aware resolution for Claude, Codex, OpenCode, and Grok. T3 resolves the active executable, verifies its owning installation from installer metadata, derives the exact update command and environment, and re-resolves installation identity immediately before and after execution.

For catalog-managed providers, one-click updates are exposed only when ownership can be verified. Unknown or ambiguous installations remain manual-only. The implementation covers native installers, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet.

What changed

• adds a declarative installation catalog with shared detector, version resolver, update action, environment, cache-key, and instructions primitives
• covers native, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet installations
• proves manager ownership from the resolved executable and manager metadata before enabling one-click updates
• bounds all installer metadata reads to 64 KiB, rejects oversized or invalid UTF-8 evidence, and caches repeated reads within one resolution
• distinguishes Homebrew formulae from casks and emits cask-aware upgrade commands
• keeps unknown or ambiguous ownership manual-only; bare commands are resolved through PATH and must be proven by the installation catalog
• pins npm updates to the verified owning global prefix, even when the resolved npm executable has a different default prefix
• carries installation-specific update environments and executes the exact resolved native executable
• re-resolves installation identity immediately before and after updating to prevent stale or mismatched updates
• updates the provider-maintenance server contract for fresh per-instance resolution and adjusts Settings for per-instance progress and verified “Check for updates” actions
• avoids mixing npm latest-version checks with native updates; native latest remains unknown until an official channel resolver is available

Related issues and superseded fixes

Closes#5629
Closes#6245
Closes#7730

This supersedes the narrower fixes proposed in #5630, #6247, #7731, and #8832.

These reports expose the same underlying correctness problem in different forms:
T3 could identify one provider installation while deriving the updater, package
name, or latest-version channel from assumptions belonging to another
installation.

This PR replaces those independent heuristics with one ownership-verified
installation model. The active executable is resolved first; its owning
installer and update target must then be proven from installer metadata.
Unknown or ambiguous installations remain manual-only, and ownership is
revalidated immediately before and after an update.

Related but intentionally out of scope: #4066, #6115, #7406, #8280, #4211,
#8247, and #8363.

• targeted lint, formatting, and diff checks
• real Claude npm update on Windows and Linux
• real Codex npm one-click updates from 0.150.0 to 0.150.1 on Windows and WSL/Linux using isolated executable prefixes (validated at commit 413ffc51); the active Scoop installation remained untouched
• real macOS prefix-pinned npm updates: Claude Code 2.1.240 → 2.1.241 and OpenCode 1.18.20 → 1.18.21 in isolated prefixes, with stable installation identity and lock target
• real macOS Homebrew ownership resolution and cask upgrade dry-run for the active Codex cask
• real Claude native Linux update from 2.1.227 to 2.1.229
• real Scoop ownership/update validation for Claude and OpenCode
• isolated Windows Scoop and WinGet ownership/no-false-update validation for Codex; no version transition was available because Scoop was already current and WinGet’s source latest was 0.146.1
• WinGet package/source metadata validation for all three provider IDs

Developed and validated iteratively in T3 Code across macOS, Linux/WSL, and Windows, with real installer/update trials and independent automated review.

Note

High Risk
Changes how provider update commands are chosen and executed; incorrect ownership logic could update the wrong install or block legitimate updates, and the lazy resolution path affects registry and settings UX.

Overview
Replaces PATH-based installer guessing with installation-aware maintenance: the server resolves the active provider binary, proves which package manager or installer owns it, and only then exposes one-click update commands (npm prefix pinning, Homebrew/Scoop/WinGet, native installers, etc.). Unverified or ambiguous installs stay manual-only.

Contract and wiring:ServerProviderShape now carries resolveMaintenance as a lazy Effect instead of a static maintenanceCapabilities. Drivers (Claude, Codex, OpenCode, Grok) use makeProviderMaintenanceResolver plus makeProviderMaintenanceCapabilitySources (cached advisory probes vs fresh resolution before updates). Provider env merges with HostProcessEnvironment; ProviderRegistry exposes resolveProviderMaintenanceCapabilitiesForInstance.

New maintenance/ stack: catalog detectors (catalogs.ts), shared types (definition.ts), ordered resolution with fail-closed manual fallback (resolver.ts), and strict semver helpers (version.ts), with broad unit coverage. Grok moves from manual-only to full package/native maintenance metadata.

Safety: bounded metadata reads, probe output limits, resolution timeouts that do not fall back to unsafe npm updates, and stricter version advisory rules (e.g. native installs without a verified latest channel).

Note

Replace package-managed maintenance resolvers with installation-aware makeProviderMaintenanceResolver

• Replaces makePackageManagedProviderMaintenanceResolver with makeProviderMaintenanceResolver across Claude, Codex, Cursor, Grok, and OpenCode drivers; definitions now use packageName, executableName, instructionsUrl, and wingetPackageId instead of npmPackageName and nested nativeUpdate.executable/lockKey.
• Introduces a new maintenance catalog/resolver subsystem in apps/server/src/provider/maintenance/ that detects installations via bounded probes, verifies ownership, resolves real executable paths, and falls back to a manual-only installation when nothing matches.
• Changes ServerProviderShape.maintenanceCapabilities from a synchronous value to an effectful resolveMaintenance: Effect<ProviderMaintenanceCapabilities>, and renames ProviderRegistry.getProviderMaintenanceCapabilitiesForInstance to resolveProviderMaintenanceCapabilitiesForInstance; all drivers, tests, and mocks are updated.
• The maintenance runner in providerMaintenanceRunner.ts now re-resolves capabilities before and after running an update, verifies identityKey and lockKey stability, requires absolute executable paths, and classifies success by version advancement via compareMaintenanceVersions.
• UI in ProviderInstanceCard.tsx and providerStatus.ts now shows a muted "Check for updates" action with a refresh icon when the advisory status is unknown but a verified updateCommand exists.
• Risk: ServerProviderShape and ProviderRegistryShape API changes break any out-of-tree implementations that read maintenanceCapabilities synchronously or call getProviderMaintenanceCapabilitiesForInstance; the runner now aborts updates if identityKey changes mid-update or if the update executable is not an absolute path.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk:🟠 High · up to 54cbe

This change routes provider updates through installer ownership checks, but the current head still has a test file that cannot compile, a Cursor update path without identity verification, and cancellation handling that can delay or bypass probe timeouts; several version and installer edge cases can also hide or misclassify updates. The PR is not merge-ready until these issues are fixed or explicitly accepted.

compareMaintenanceVersions returns number | null; it returns null when either side does not parse. The strict === -1 check then falls through to { status: "current" }. A provider with a non-semver version string is reported as up to date instead of unknown.

🐛 Proposed fix

- if (compareMaintenanceVersions(input.currentVersion, input.latestVersion) === -1) {+ const comparison = compareMaintenanceVersions(input.currentVersion, input.latestVersion);+ if (comparison === null) {+ return { status: "unknown", message: null };+ }+ if (comparison < 0) {
return {
status: "behind_latest",
message: PROVIDER_UPDATE_ACTION_TOAST_MESSAGE,
};
}

Select the greatest version instead of the first regex match.

The parser takes the first semver-shaped token in the winget show --versions output. The command prints a table with a header, and the row order is not a documented contract. If the output ever lists the oldest version first, or a header field contains a version-shaped token, latestVersion becomes wrong and the update advisory misleads the user. Compare all candidates and keep the greatest one.

Confirm canonicalPath never receives relative paths.

pathApi.resolve uses process.cwd() as the base. When platform is "win32" and the host is POSIX (or the reverse), a relative input resolves against a foreign-format cwd and produces a meaningless canonical path. All current callers pass absolute paths, so this is a robustness note only. Consider returning early or normalizing without resolve when pathApi.isAbsolute(path) is false.

Add a test for the undetermined short-circuit and for the native update environment.

Two behaviors of this cohort have no coverage here:

1. resolveInstallation returns manual-only and skips the npm fallback when an owned definition reports Undetermined, even for a bare command with npm available. This branch decides whether a wrong update command can run, so it needs a focused test. A Scoop shim with an unreadable .shim file plus commands: { npm } reproduces it, and the expected label is "Unknown installation — verification failed".
2. nativeDefinition passes native.environment(executable, context.environment) into update.environment. No test asserts that the resolved installation carries that environment.

The run stub at line 54 ignores its environment argument. Capture it if you assert environment propagation.

As per coding guidelines: "Backend behavior changes must include focused tests for that behavior".

Avoid the implicit "codex" executable-name default.

The fallback chain resolves executableName to "codex" for every provider that is not claudeAgent or opencode. All three drivers pass executableName explicitly today, so this branch only serves other providers, including future Cursor and Grok adapters and the test fixtures. A wrong executable name feeds makeProviderInstallationCatalog and can produce incorrect detection instead of a clear failure.

Make executableName required on ProviderMaintenanceDefinition, or derive it from packageName instead of a hard-coded provider name.

The coding guidelines require an explicit decision for every provider adapter: "Provider-shaped features require an explicit decision for every provider adapter: Codex, Claude, Cursor, Grok, and OpenCode, including an explicit unsupported decision where necessary."

I've opened #9325 which carries those pieces (and the per-instance settings state) onto current main and closes the same three issues. I didn't push here because the branch is 61 commits behind and the changes are structural rather than a rebase. Two things I couldn't land as-is:

• Native installs (~/.local/bin/claude, standalone Codex, ~/.opencode/bin) set latestVersion: null, which drops them to unknown and removes the launch toast for the default install path. Native and npm share a version train, so fix(server): only run provider updates through the installer that owns the binary #9325 keeps the registry as the latest source there and only lets Homebrew override it.
• The Vite+ detector runs vp root -g, which isn't a vp subcommand (exit 2), so it always falls through to npm.

Scoop and WinGet support look useful but need their own issue and someone on Windows to validate; the identity hashing, wrapper-script parsing, and three-way re-resolution in the runner I simplified to a single fresh read under the lock. Happy to review a follow-up for the Windows managers if you want to split them out.

Problem

T3 could resolve a provider executable from one concrete installation while applying an update through a different installer or package-manager prefix. For example, the active executable could be owned by Scoop or by one npm prefix while the updater selected from PATH targeted another installation.

This change replaces installer guessing with installation-aware resolution for Claude, Codex, OpenCode, and Grok. T3 resolves the active executable, verifies its owning installation from installer metadata, derives the exact update command and environment, and re-resolves installation identity immediately before and after execution.

For catalog-managed providers, one-click updates are exposed only when ownership can be verified. Unknown or ambiguous installations remain manual-only. The implementation covers native installers, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet.

What changed

• adds a declarative installation catalog with shared detector, version resolver, update action, environment, cache-key, and instructions primitives
• covers native, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet installations
• proves manager ownership from the resolved executable and manager metadata before enabling one-click updates
• bounds all installer metadata reads to 64 KiB, rejects oversized or invalid UTF-8 evidence, and caches repeated reads within one resolution
• distinguishes Homebrew formulae from casks and emits cask-aware upgrade commands
• keeps unknown or ambiguous ownership manual-only; bare commands are resolved through PATH and must be proven by the installation catalog
• pins npm updates to the verified owning global prefix, even when the resolved npm executable has a different default prefix
• carries installation-specific update environments and executes the exact resolved native executable
• re-resolves installation identity immediately before and after updating to prevent stale or mismatched updates
• updates the provider-maintenance server contract for fresh per-instance resolution and adjusts Settings for per-instance progress and verified “Check for updates” actions
• avoids mixing npm latest-version checks with native updates; native latest remains unknown until an official channel resolver is available

Related issues and superseded fixes

Closes#5629
Closes#6245
Closes#7730

This supersedes the narrower fixes proposed in #5630, #6247, #7731, and #8832.

These reports expose the same underlying correctness problem in different forms:
T3 could identify one provider installation while deriving the updater, package
name, or latest-version channel from assumptions belonging to another
installation.

This PR replaces those independent heuristics with one ownership-verified
installation model. The active executable is resolved first; its owning
installer and update target must then be proven from installer metadata.
Unknown or ambiguous installations remain manual-only, and ownership is
revalidated immediately before and after an update.

Related but intentionally out of scope: #4066, #6115, #7406, #8280, #4211,

Note

High Risk
Changes how provider update commands are chosen and executed; incorrect ownership logic could update the wrong install or block legitimate updates, and the lazy resolution path affects registry and settings UX.

Overview
Replaces PATH-based installer guessing with installation-aware maintenance: the server resolves the active provider binary, proves which package manager or installer owns it, and only then exposes one-click update commands (npm prefix pinning, Homebrew/Scoop/WinGet, native installers, etc.). Unverified or ambiguous installs stay manual-only.

Contract and wiring:ServerProviderShape now carries resolveMaintenance as a lazy Effect instead of a static maintenanceCapabilities. Drivers (Claude, Codex, OpenCode, Grok) use makeProviderMaintenanceResolver plus makeProviderMaintenanceCapabilitySources (cached advisory probes vs fresh resolution before updates). Provider env merges with HostProcessEnvironment; ProviderRegistry exposes resolveProviderMaintenanceCapabilitiesForInstance.

New maintenance/ stack: catalog detectors (catalogs.ts), shared types (definition.ts), ordered resolution with fail-closed manual fallback (resolver.ts), and strict semver helpers (version.ts), with broad unit coverage. Grok moves from manual-only to full package/native maintenance metadata.

Safety: bounded metadata reads, probe output limits, resolution timeouts that do not fall back to unsafe npm updates, and stricter version advisory rules (e.g. native installs without a verified latest channel).

Note

Replace package-managed maintenance resolvers with installation-aware makeProviderMaintenanceResolver

• Replaces makePackageManagedProviderMaintenanceResolver with makeProviderMaintenanceResolver across Claude, Codex, Cursor, Grok, and OpenCode drivers; definitions now use packageName, executableName, instructionsUrl, and wingetPackageId instead of npmPackageName and nested nativeUpdate.executable/lockKey.
• Introduces a new maintenance catalog/resolver subsystem in apps/server/src/provider/maintenance/ that detects installations via bounded probes, verifies ownership, resolves real executable paths, and falls back to a manual-only installation when nothing matches.
• Changes ServerProviderShape.maintenanceCapabilities from a synchronous value to an effectful resolveMaintenance: Effect<ProviderMaintenanceCapabilities>, and renames ProviderRegistry.getProviderMaintenanceCapabilitiesForInstance to resolveProviderMaintenanceCapabilitiesForInstance; all drivers, tests, and mocks are updated.
• The maintenance runner in providerMaintenanceRunner.ts now re-resolves capabilities before and after running an update, verifies identityKey and lockKey stability, requires absolute executable paths, and classifies success by version advancement via compareMaintenanceVersions.
• UI in ProviderInstanceCard.tsx and providerStatus.ts now shows a muted "Check for updates" action with a refresh icon when the advisory status is unknown but a verified updateCommand exists.
• Risk: ServerProviderShape and ProviderRegistryShape API changes break any out-of-tree implementations that read maintenanceCapabilities synchronously or call getProviderMaintenanceCapabilitiesForInstance; the runner now aborts updates if identityKey changes mid-update or if the update executable is not an absolute path.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk:🟠 High · up to 54cbe

This change routes provider updates through installer ownership checks, but the current head still has a test file that cannot compile, a Cursor update path without identity verification, and cancellation handling that can delay or bypass probe timeouts; several version and installer edge cases can also hide or misclassify updates. The PR is not merge-ready until these issues are fixed or explicitly accepted.

Map an unparsable version comparison to unknown.

Select the greatest version instead of the first regex match.

The parser takes the first semver-shaped token in the winget show --versions output. The command prints a table with a header, and the row order is not a documented contract.

Confirm canonicalPath never receives relative paths.

pathApi.resolve uses process.cwd() as the base. When platform is "win32" and the host is POSIX (or the reverse), a relative input resolves against a foreign-format cwd and produces a meaningless canonical path. All current callers pass absolute paths, so this is a robustness note only. Consider returning early or normalizing without resolve when pathApi.isAbsolute(path) is false.

Add a test for the undetermined short-circuit and for the native update environment.

Two behaviors of this cohort have no coverage here:

1. resolveInstallation returns manual-only and skips the npm fallback when an owned definition reports Undetermined, even for a bare command with npm available. This branch decides whether a wrong update command can run, so it needs a focused test. A Scoop shim with an unreadable .shim file plus commands: { npm } reproduces it, and the expected label is "Unknown installation — verification failed".
2. nativeDefinition passes native.environment(executable, context.environment) into update.environment. No test asserts that the resolved installation carries that environment.

The run stub at line 54 ignores its environment argument. Capture it if you assert environment propagation.

Avoid the implicit "codex" executable-name default.

The fallback chain resolves executableName to "codex" for every provider that is not claudeAgent or opencode. All three drivers pass executableName explicitly today, so this branch only serves other providers, including future Cursor and Grok adapters and the test fixtures. A wrong executable name feeds makeProviderInstallationCatalog and can produce incorrect detection instead of a clear failure.

Make executableName required on ProviderMaintenanceDefinition, or derive it from packageName instead of a hard-coded provider name.

The coding guidelines require an explicit decision for every provider adapter: "Provider-shaped features require an explicit decision for every provider adapter: Codex, Claude, Cursor, Grok, and OpenCode, including an explicit unsupported decision where necessary."

Add coverage for capabilities without an identityKey.

Both new tests set identityKey on the stored and refreshed capabilities. The guards in providerMaintenanceRunner.ts at Lines 365-370 and 381-394 are conditional on identityKey being present, so the legacy path stays untested. That path is where a changed installation manager can still reach the spawn step. Add a test where getProviderMaintenanceCapabilitiesForInstance returns capabilities without identityKey and the refreshed capabilities carry a different lockKey.

The coding guidelines require: "Backend behavior changes must include focused tests for that behavior, and tests must not rely on arbitrary timeouts to pass."

[juliusmarminge]

Thanks for digging into this — you found the right root cause (T3 resolving one install and updating another) and the npm --prefix pinning plus Homebrew formula/cask detection were the correct fixes for #5629/#6245/#7730.

I've opened #9325 which carries those pieces (and the per-instance settings state) onto current main and closes the same three issues. I didn't push here because the branch is 61 commits behind and the changes are structural rather than a rebase. Two things I couldn't land as-is:

• Native installs (~/.local/bin/claude, standalone Codex, ~/.opencode/bin) set latestVersion: null, which drops them to unknown and removes the launch toast for the default install path. Native and npm share a version train, so fix(server): only run provider updates through the installer that owns the binary #9325 keeps the registry as the latest source there and only lets Homebrew override it.
• The Vite+ detector runs vp root -g, which isn't a vp subcommand (exit 2), so it always falls through to npm.

Scoop and WinGet support look useful but need their own issue and someone on Windows to validate; the identity hashing, wrapper-script parsing, and three-way re-resolution in the runner I simplified to a single fresh read under the lock. Happy to review a follow-up for the Windows managers if you want to split them out.

Thanks, happy to take the Scoop/WinGet follow-up and validate it on Windows!

Problem

T3 could resolve a provider executable from one concrete installation while applying an update through a different installer or package-manager prefix. For example, the active executable could be owned by Scoop or by one npm prefix while the updater selected from PATH targeted another installation.

This change replaces installer guessing with installation-aware resolution for Claude, Codex, OpenCode, and Grok. T3 resolves the active executable, verifies its owning installation from installer metadata, derives the exact update command and environment, and re-resolves installation identity immediately before and after execution.

For catalog-managed providers, one-click updates are exposed only when ownership can be verified. Unknown or ambiguous installations remain manual-only. The implementation covers native installers, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet.

What changed

• adds a declarative installation catalog with shared detector, version resolver, update action, environment, cache-key, and instructions primitives
• covers native, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet installations
• proves manager ownership from the resolved executable and manager metadata before enabling one-click updates
• bounds all installer metadata reads to 64 KiB, rejects oversized or invalid UTF-8 evidence, and caches repeated reads within one resolution
• distinguishes Homebrew formulae from casks and emits cask-aware upgrade commands
• keeps unknown or ambiguous ownership manual-only; bare commands are resolved through PATH and must be proven by the installation catalog
• pins npm updates to the verified owning global prefix, even when the resolved npm executable has a different default prefix
• carries installation-specific update environments and executes the exact resolved native executable
• re-resolves installation identity immediately before and after updating to prevent stale or mismatched updates
• updates the provider-maintenance server contract for fresh per-instance resolution and adjusts Settings for per-instance progress and verified “Check for updates” actions
• avoids mixing npm latest-version checks with native updates; native latest remains unknown until an official channel resolver is available

Related issues and superseded fixes

Closes#5629
Closes#6245
Closes#7730

This supersedes the narrower fixes proposed in #5630, #6247, #7731, and #8832.

These reports expose the same underlying correctness problem in different forms:
T3 could identify one provider installation while deriving the updater, package
name, or latest-version channel from assumptions belonging to another
installation.

This PR replaces those independent heuristics with one ownership-verified
installation model. The active executable is resolved first; its owning
installer and update target must then be proven from installer metadata.
Unknown or ambiguous installations remain manual-only, and ownership is
revalidated immediately before and after an update.

Related but intentionally out of scope: #4066, #6115, #7406, #8280, #4211,
#8247, and #8363.

Note

High Risk
Changes how provider update commands are chosen and executed; incorrect ownership logic could update the wrong install or block legitimate updates, and the lazy resolution path affects registry and settings UX.

Overview
Replaces PATH-based installer guessing with installation-aware maintenance: the server resolves the active provider binary, proves which package manager or installer owns it, and only then exposes one-click update commands (npm prefix pinning, Homebrew/Scoop/WinGet, native installers, etc.). Unverified or ambiguous installs stay manual-only.

Contract and wiring:ServerProviderShape now carries resolveMaintenance as a lazy Effect instead of a static maintenanceCapabilities. Drivers (Claude, Codex, OpenCode, Grok) use makeProviderMaintenanceResolver plus makeProviderMaintenanceCapabilitySources (cached advisory probes vs fresh resolution before updates). Provider env merges with HostProcessEnvironment; ProviderRegistry exposes resolveProviderMaintenanceCapabilitiesForInstance.

New maintenance/ stack: catalog detectors (catalogs.ts), shared types (definition.ts), ordered resolution with fail-closed manual fallback (resolver.ts), and strict semver helpers (version.ts), with broad unit coverage. Grok moves from manual-only to full package/native maintenance metadata.

Safety: bounded metadata reads, probe output limits, resolution timeouts that do not fall back to unsafe npm updates, and stricter version advisory rules (e.g. native installs without a verified latest channel).

Note

Replace package-managed maintenance resolvers with installation-aware makeProviderMaintenanceResolver

• Replaces makePackageManagedProviderMaintenanceResolver with makeProviderMaintenanceResolver across Claude, Codex, Cursor, Grok, and OpenCode drivers; definitions now use packageName, executableName, instructionsUrl, and wingetPackageId instead of npmPackageName and nested nativeUpdate.executable/lockKey.
• Introduces a new maintenance catalog/resolver subsystem in apps/server/src/provider/maintenance/ that detects installations via bounded probes, verifies ownership, resolves real executable paths, and falls back to a manual-only installation when nothing matches.
• Changes ServerProviderShape.maintenanceCapabilities from a synchronous value to an effectful resolveMaintenance: Effect<ProviderMaintenanceCapabilities>, and renames ProviderRegistry.getProviderMaintenanceCapabilitiesForInstance to resolveProviderMaintenanceCapabilitiesForInstance; all drivers, tests, and mocks are updated.
• The maintenance runner in providerMaintenanceRunner.ts now re-resolves capabilities before and after running an update, verifies identityKey and lockKey stability, requires absolute executable paths, and classifies success by version advancement via compareMaintenanceVersions.
• UI in ProviderInstanceCard.tsx and providerStatus.ts now shows a muted "Check for updates" action with a refresh icon when the advisory status is unknown but a verified updateCommand exists.
• Risk: ServerProviderShape and ProviderRegistryShape API changes break any out-of-tree implementations that read maintenanceCapabilities synchronously or call getProviderMaintenanceCapabilitiesForInstance; the runner now aborts updates if identityKey changes mid-update or if the update executable is not an absolute path.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk:🟠 High · up to 54cbe

This change routes provider updates through installer ownership checks, but the current head still has a test file that cannot compile, a Cursor update path without identity verification, and cancellation handling that can delay or bypass probe timeouts; several version and installer edge cases can also hide or misclassify updates. The PR is not merge-ready until these issues are fixed or explicitly accepted.

575-584: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Map an unparsable version comparison to unknown.

compareMaintenanceVersions returns number | null; it returns null when either side does not parse. The strict === -1 check then falls through to { status: "current" }. A provider with a non-semver version string is reported as up to date instead of unknown.

🐛 Proposed fix

- if (compareMaintenanceVersions(input.currentVersion, input.latestVersion) === -1) {+ const comparison = compareMaintenanceVersions(input.currentVersion, input.latestVersion);+ if (comparison === null) {+ return { status: "unknown", message: null };+ }+ if (comparison < 0) {
return {
status: "behind_latest",
message: PROVIDER_UPDATE_ACTION_TOAST_MESSAGE,
};
}

Alias the resolver directly instead of wrapping it in a second Effect.fn.

resolveProviderMaintenanceCapabilitiesForInstance is already an Effect.fn. Wrapping it again adds a second tracing span for every call with no behavior change. Assign the function directly if you want the deprecated name to remain.

Select the greatest version instead of the first regex match.

The parser takes the first semver-shaped token in the winget show --versions output. The command prints a table with a header, and the row order is not a documented contract. If the output ever lists the oldest version first, or a header field contains a version-shaped token, latestVersion becomes wrong and the update advisory misleads the user. Compare all candidates and keep the greatest one.

♻️ Proposed change

- const latest =- (show?.stdout.match(/\b\d+\.\d+\.\d+(?:-[0-9A-Za-z.-]+)?\b/g) ??

Carry the Homebrew formula in the evidence instead of a non-null assertion.

detect returns notMatched when input.homebrewFormula is null, so resolve uses input.homebrewFormula!. The assertion couples resolve to the guard in detect. Add formula to the evidence type and read it in resolve. The type then proves the value is present.

Confirm canonicalPath never receives relative paths.

pathApi.resolve uses process.cwd() as the base. When platform is "win32" and the host is POSIX (or the reverse), a relative input resolves against a foreign-format cwd and produces a meaningless canonical path. All current callers pass absolute paths, so this is a robustness note only. Consider returning early or normalizing without resolve when pathApi.isAbsolute(path) is false.

Log the aggregated undetermined reasons before discarding them.

resolveFirst builds reasons for every Undetermined detection, but resolveInstallation drops the array and returns only a generic manual installation.

Add a test for the undetermined short-circuit and for the native update environment.

Two behaviors of this cohort have no coverage here:

1. resolveInstallation returns manual-only and skips the npm fallback when an owned definition reports Undetermined, even for a bare command with npm available. This branch decides whether a wrong update command can run, so it needs a focused test. A Scoop shim with an unreadable .shim file plus commands: { npm } reproduces it, and the expected label is "Unknown installation — verification failed".
2. nativeDefinition passes native.environment(executable, context.environment) into update.environment. No test asserts that the resolved installation carries that environment.

The run stub at line 54 ignores its environment argument. Capture it if you assert environment propagation.

As per coding guidelines: "Backend behavior changes must include focused tests for that behavior".

Move the Codex standalone installer rule into this definition.

Codex ownership knowledge now lives in two files, and a reader of this file sees no native support.

Avoid the implicit "codex" executable-name default.

The fallback chain resolves executableName to "codex" for every provider that is not claudeAgent or opencode. All three drivers pass executableName explicitly today, so this branch only serves other providers, including future Cursor and Grok adapters and the test fixtures. A wrong executable name feeds makeProviderInstallationCatalog and can produce incorrect detection instead of a clear failure.

Make executableName required on ProviderMaintenanceDefinition, or derive it from packageName instead of a hard-coded provider name.

The coding guidelines require an explicit decision for every provider adapter: "Provider-shaped features require an explicit decision for every provider adapter: Codex, Claude, Cursor, Grok, and OpenCode, including an explicit unsupported decision where necessary."

Add coverage for capabilities without an identityKey.

Both new tests set identityKey on the stored and refreshed capabilities. The guards in providerMaintenanceRunner.ts at Lines 365-370 and 381-394 are conditional on identityKey being present, so the legacy path stays untested. That path is where a changed installation manager can still reach the spawn step. Add a test where getProviderMaintenanceCapabilitiesForInstance returns capabilities without identityKey and the refreshed capabilities carry a different lockKey.

Thanks for digging into this — you found the right root cause (T3 resolving one install and updating another) and the npm --prefix pinning plus Homebrew formula/cask detection were the correct fixes for #5629/#6245/#7730.

I've opened #9325 which carries those pieces (and the per-instance settings state) onto current main and closes the same three issues. I didn't push here because the branch is 61 commits behind and the changes are structural rather than a rebase. Two things I couldn't land as-is:

• Native installs (~/.local/bin/claude, standalone Codex, ~/.opencode/bin) set latestVersion: null, which drops them to unknown and removes the launch toast for the default install path. Native and npm share a version train, so fix(server): only run provider updates through the installer that owns the binary #9325 keeps the registry as the latest source there and only lets Homebrew override it.
• The Vite+ detector runs vp root -g, which isn't a vp subcommand (exit 2), so it always falls through to npm.

Scoop and WinGet support look useful but need their own issue and someone on Windows to validate; the identity hashing, wrapper-script parsing, and three-way re-resolution in the runner I simplified to a single fresh read under the lock. Happy to review a follow-up for the Windows managers if you want to split them out.

Problem

T3 could resolve a provider executable from one concrete installation while applying an update through a different installer or package-manager prefix. For example, the active executable could be owned by Scoop or by one npm prefix while the updater selected from PATH targeted another installation.

This change replaces installer guessing with installation-aware resolution for Claude, Codex, OpenCode, and Grok. T3 resolves the active executable, verifies its owning installation from installer metadata, derives the exact update command and environment, and re-resolves installation identity immediately before and after execution.

For catalog-managed providers, one-click updates are exposed only when ownership can be verified. Unknown or ambiguous installations remain manual-only. The implementation covers native installers, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet.

What changed

• adds a declarative installation catalog with shared detector, version resolver, update action, environment, cache-key, and instructions primitives
• covers native, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet installations
• proves manager ownership from the resolved executable and manager metadata before enabling one-click updates
• bounds all installer metadata reads to 64 KiB, rejects oversized or invalid UTF-8 evidence, and caches repeated reads within one resolution
• distinguishes Homebrew formulae from casks and emits cask-aware upgrade commands
• keeps unknown or ambiguous ownership manual-only; bare commands are resolved through PATH and must be proven by the installation catalog
• pins npm updates to the verified owning global prefix, even when the resolved npm executable has a different default prefix
• carries installation-specific update environments and executes the exact resolved native executable
• re-resolves installation identity immediately before and after updating to prevent stale or mismatched updates
• updates the provider-maintenance server contract for fresh per-instance resolution and adjusts Settings for per-instance progress and verified “Check for updates” actions
• avoids mixing npm latest-version checks with native updates; native latest remains unknown until an official channel resolver is available

Related issues and superseded fixes

Closes#5629
Closes#6245
Closes#7730

This supersedes the narrower fixes proposed in #5630, #6247, #7731, and #8832.

These reports expose the same underlying correctness problem in different forms:
T3 could identify one provider installation while deriving the updater, package
name, or latest-version channel from assumptions belonging to another
installation.

This PR replaces those independent heuristics with one ownership-verified
installation model. The active executable is resolved first; its owning
installer and update target must then be proven from installer metadata.
Unknown or ambiguous installations remain manual-only, and ownership is
revalidated immediately before and after an update.

Related but intentionally out of scope: #4066, #6115, #7406, #8280, #4211,
#8247, and #8363.

Note

High Risk
Changes how provider update commands are chosen and executed; incorrect ownership logic could update the wrong install or block legitimate updates, and the lazy resolution path affects registry and settings UX.

Overview
Replaces PATH-based installer guessing with installation-aware maintenance: the server resolves the active provider binary, proves which package manager or installer owns it, and only then exposes one-click update commands (npm prefix pinning, Homebrew/Scoop/WinGet, native installers, etc.). Unverified or ambiguous installs stay manual-only.

Contract and wiring:ServerProviderShape now carries resolveMaintenance as a lazy Effect instead of a static maintenanceCapabilities. Drivers (Claude, Codex, OpenCode, Grok) use makeProviderMaintenanceResolver plus makeProviderMaintenanceCapabilitySources (cached advisory probes vs fresh resolution before updates). Provider env merges with HostProcessEnvironment; ProviderRegistry exposes resolveProviderMaintenanceCapabilitiesForInstance.

New maintenance/ stack: catalog detectors (catalogs.ts), shared types (definition.ts), ordered resolution with fail-closed manual fallback (resolver.ts), and strict semver helpers (version.ts), with broad unit coverage. Grok moves from manual-only to full package/native maintenance metadata.

Safety: bounded metadata reads, probe output limits, resolution timeouts that do not fall back to unsafe npm updates, and stricter version advisory rules (e.g. native installs without a verified latest channel).

Note

Replace package-managed maintenance resolvers with installation-aware makeProviderMaintenanceResolver

• Replaces makePackageManagedProviderMaintenanceResolver with makeProviderMaintenanceResolver across Claude, Codex, Cursor, Grok, and OpenCode drivers; definitions now use packageName, executableName, instructionsUrl, and wingetPackageId instead of npmPackageName and nested nativeUpdate.executable/lockKey.
• Introduces a new maintenance catalog/resolver subsystem in apps/server/src/provider/maintenance/ that detects installations via bounded probes, verifies ownership, resolves real executable paths, and falls back to a manual-only installation when nothing matches.
• Changes ServerProviderShape.maintenanceCapabilities from a synchronous value to an effectful resolveMaintenance: Effect<ProviderMaintenanceCapabilities>, and renames ProviderRegistry.getProviderMaintenanceCapabilitiesForInstance to resolveProviderMaintenanceCapabilitiesForInstance; all drivers, tests, and mocks are updated.
• The maintenance runner in providerMaintenanceRunner.ts now re-resolves capabilities before and after running an update, verifies identityKey and lockKey stability, requires absolute executable paths, and classifies success by version advancement via compareMaintenanceVersions.
• UI in ProviderInstanceCard.tsx and providerStatus.ts now shows a muted "Check for updates" action with a refresh icon when the advisory status is unknown but a verified updateCommand exists.
• Risk: ServerProviderShape and ProviderRegistryShape API changes break any out-of-tree implementations that read maintenanceCapabilities synchronously or call getProviderMaintenanceCapabilitiesForInstance; the runner now aborts updates if identityKey changes mid-update or if the update executable is not an absolute path.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk:🟠 High · up to 54cbe

This change routes provider updates through installer ownership checks, but the current head still has a test file that cannot compile, a Cursor update path without identity verification, and cancellation handling that can delay or bypass probe timeouts; several version and installer edge cases can also hide or misclassify updates. The PR is not merge-ready until these issues are fixed or explicitly accepted.

Map an unparsable version comparison to unknown.

compareMaintenanceVersions returns number | null; it returns null when either side does not parse. The strict === -1 check then falls through to { status: "current" }. A provider with a non-semver version string is reported as up to date instead of unknown.

Select the greatest version instead of the first regex match.

The parser takes the first semver-shaped token in the winget show --versions output. The command prints a table with a header, and the row order is not a documented contract. If the output ever lists the oldest version first, or a header field contains a version-shaped token, latestVersion becomes wrong and the update advisory misleads the user. Compare all candidates and keep the greatest one.

Confirm canonicalPath never receives relative paths.

pathApi.resolve uses process.cwd() as the base. When platform is "win32" and the host is POSIX (or the reverse), a relative input resolves against a foreign-format cwd and produces a meaningless canonical path. All current callers pass absolute paths, so this is a robustness note only. Consider returning early or normalizing without resolve when pathApi.isAbsolute(path) is false.

Add a test for the undetermined short-circuit and for the native update environment.

Two behaviors of this cohort have no coverage here:

1. resolveInstallation returns manual-only and skips the npm fallback when an owned definition reports Undetermined, even for a bare command with npm available. This branch decides whether a wrong update command can run, so it needs a focused test. A Scoop shim with an unreadable .shim file plus commands: { npm } reproduces it, and the expected label is "Unknown installation — verification failed".
2. nativeDefinition passes native.environment(executable, context.environment) into update.environment. No test asserts that the resolved installation carries that environment.

The run stub at line 54 ignores its environment argument. Capture it if you assert environment propagation.

Avoid the implicit "codex" executable-name default.

The fallback chain resolves executableName to "codex" for every provider that is not claudeAgent or opencode. All three drivers pass executableName explicitly today, so this branch only serves other providers, including future Cursor and Grok adapters and the test fixtures. A wrong executable name feeds makeProviderInstallationCatalog and can produce incorrect detection instead of a clear failure.

Make executableName required on ProviderMaintenanceDefinition, or derive it from packageName instead of a hard-coded provider name.

The coding guidelines require an explicit decision for every provider adapter: "Provider-shaped features require an explicit decision for every provider adapter: Codex, Claude, Cursor, Grok, and OpenCode, including an explicit unsupported decision where necessary."

Add coverage for capabilities without an identityKey.

Both new tests set identityKey on the stored and refreshed capabilities. The guards in providerMaintenanceRunner.ts at Lines 365-370 and 381-394 are conditional on identityKey being present, so the legacy path stays untested. That path is where a changed installation manager can still reach the spawn step. Add a test where getProviderMaintenanceCapabilitiesForInstance returns capabilities without identityKey and the refreshed capabilities carry a different lockKey.

The coding guidelines require: "Backend behavior changes must include focused tests for that behavior, and tests must not rely on arbitrary timeouts to pass."

[juliusmarminge]

Thanks for digging into this — you found the right root cause (T3 resolving one install and updating another) and the npm --prefix pinning plus Homebrew formula/cask detection were the correct fixes for #5629/#6245/#7730.

I've opened #9325 which carries those pieces (and the per-instance settings state) onto current main and closes the same three issues. I didn't push here because the branch is 61 commits behind and the changes are structural rather than a rebase. Two things I couldn't land as-is:

• Native installs (~/.local/bin/claude, standalone Codex, ~/.opencode/bin) set latestVersion: null, which drops them to unknown and removes the launch toast for the default install path. Native and npm share a version train, so fix(server): only run provider updates through the installer that owns the binary #9325 keeps the registry as the latest source there and only lets Homebrew override it.
• The Vite+ detector runs vp root -g, which isn't a vp subcommand (exit 2), so it always falls through to npm.

Scoop and WinGet support look useful but need their own issue and someone on Windows to validate; the identity hashing, wrapper-script parsing, and three-way re-resolution in the runner I simplified to a single fresh read under the lock. Happy to review a follow-up for the Windows managers if you want to split them out.

Thanks, happy to take the Scoop/WinGet follow-up and validate it on Windows!

Problem

T3 could resolve a provider executable from one concrete installation while applying an update through a different installer or package-manager prefix. For example, the active executable could be owned by Scoop or by one npm prefix while the updater selected from PATH targeted another installation.

This change replaces installer guessing with installation-aware resolution for Claude, Codex, OpenCode, and Grok. T3 resolves the active executable, verifies its owning installation from installer metadata, derives the exact update command and environment, and re-resolves installation identity immediately before and after execution.

For catalog-managed providers, one-click updates are exposed only when ownership can be verified. Unknown or ambiguous installations remain manual-only. The implementation covers native installers, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet.

What changed

• adds a declarative installation catalog with shared detector, version resolver, update action, environment, cache-key, and instructions primitives
• covers native, npm, pnpm, Bun, Vite+ compatibility, Homebrew, Scoop, and portable WinGet installations
• proves manager ownership from the resolved executable and manager metadata before enabling one-click updates
• bounds all installer metadata reads to 64 KiB, rejects oversized or invalid UTF-8 evidence, and caches repeated reads within one resolution
• distinguishes Homebrew formulae from casks and emits cask-aware upgrade commands
• keeps unknown or ambiguous ownership manual-only; bare commands are resolved through PATH and must be proven by the installation catalog
• pins npm updates to the verified owning global prefix, even when the resolved npm executable has a different default prefix
• carries installation-specific update environments and executes the exact resolved native executable
• re-resolves installation identity immediately before and after updating to prevent stale or mismatched updates
• updates the provider-maintenance server contract for fresh per-instance resolution and adjusts Settings for per-instance progress and verified “Check for updates” actions
• avoids mixing npm latest-version checks with native updates; native latest remains unknown until an official channel resolver is available

Related issues and superseded fixes

Closes#5629
Closes#6245
Closes#7730

This supersedes the narrower fixes proposed in #5630, #6247, #7731, and #8832.

These reports expose the same underlying correctness problem in different forms:
T3 could identify one provider installation while deriving the updater, package
name, or latest-version channel from assumptions belonging to another
installation.

This PR replaces those independent heuristics with one ownership-verified
installation model. The active executable is resolved first; its owning
installer and update target must then be proven from installer metadata.
Unknown or ambiguous installations remain manual-only, and ownership is
revalidated immediately before and after an update.

Related but intentionally out of scope: #4066, #6115, #7406, #8280, #4211,
#8247, and #8363.

Note

High Risk
Changes how provider update commands are chosen and executed; incorrect ownership logic could update the wrong install or block legitimate updates, and the lazy resolution path affects registry and settings UX.

Overview
Replaces PATH-based installer guessing with installation-aware maintenance: the server resolves the active provider binary, proves which package manager or installer owns it, and only then exposes one-click update commands (npm prefix pinning, Homebrew/Scoop/WinGet, native installers, etc.). Unverified or ambiguous installs stay manual-only.

Contract and wiring:ServerProviderShape now carries resolveMaintenance as a lazy Effect instead of a static maintenanceCapabilities. Drivers (Claude, Codex, OpenCode, Grok) use makeProviderMaintenanceResolver plus makeProviderMaintenanceCapabilitySources (cached advisory probes vs fresh resolution before updates). Provider env merges with HostProcessEnvironment; ProviderRegistry exposes resolveProviderMaintenanceCapabilitiesForInstance.

New maintenance/ stack: catalog detectors (catalogs.ts), shared types (definition.ts), ordered resolution with fail-closed manual fallback (resolver.ts), and strict semver helpers (version.ts), with broad unit coverage. Grok moves from manual-only to full package/native maintenance metadata.

Safety: bounded metadata reads, probe output limits, resolution timeouts that do not fall back to unsafe npm updates, and stricter version advisory rules (e.g. native installs without a verified latest channel).

Note

Replace package-managed maintenance resolvers with installation-aware makeProviderMaintenanceResolver

• Replaces makePackageManagedProviderMaintenanceResolver with makeProviderMaintenanceResolver across Claude, Codex, Cursor, Grok, and OpenCode drivers; definitions now use packageName, executableName, instructionsUrl, and wingetPackageId instead of npmPackageName and nested nativeUpdate.executable/lockKey.
• Introduces a new maintenance catalog/resolver subsystem in apps/server/src/provider/maintenance/ that detects installations via bounded probes, verifies ownership, resolves real executable paths, and falls back to a manual-only installation when nothing matches.
• Changes ServerProviderShape.maintenanceCapabilities from a synchronous value to an effectful resolveMaintenance: Effect<ProviderMaintenanceCapabilities>, and renames ProviderRegistry.getProviderMaintenanceCapabilitiesForInstance to resolveProviderMaintenanceCapabilitiesForInstance; all drivers, tests, and mocks are updated.
• The maintenance runner in providerMaintenanceRunner.ts now re-resolves capabilities before and after running an update, verifies identityKey and lockKey stability, requires absolute executable paths, and classifies success by version advancement via compareMaintenanceVersions.
• UI in ProviderInstanceCard.tsx and providerStatus.ts now shows a muted "Check for updates" action with a refresh icon when the advisory status is unknown but a verified updateCommand exists.
• Risk: ServerProviderShape and ProviderRegistryShape API changes break any out-of-tree implementations that read maintenanceCapabilities synchronously or call getProviderMaintenanceCapabilitiesForInstance; the runner now aborts updates if identityKey changes mid-update or if the update executable is not an absolute path.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk:🟠 High · up to 54cbe

This change routes provider updates through installer ownership checks, but the current head still has a test file that cannot compile, a Cursor update path without identity verification, and cancellation handling that can delay or bypass probe timeouts; several version and installer edge cases can also hide or misclassify updates. The PR is not merge-ready until these issues are fixed or explicitly accepted.

575-584: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Map an unparsable version comparison to unknown.

compareMaintenanceVersions returns number | null; it returns null when either side does not parse. The strict === -1 check then falls through to { status: "current" }. A provider with a non-semver version string is reported as up to date instead of unknown.

🐛 Proposed fix

- if (compareMaintenanceVersions(input.currentVersion, input.latestVersion) === -1) {+ const comparison = compareMaintenanceVersions(input.currentVersion, input.latestVersion);+ if (comparison === null) {+ return { status: "unknown", message: null };+ }+ if (comparison < 0) {
return {
status: "behind_latest",
message: PROVIDER_UPDATE_ACTION_TOAST_MESSAGE,
};
}

Select the greatest version instead of the first regex match.

The parser takes the first semver-shaped token in the winget show --versions output. The command prints a table with a header, and the row order is not a documented contract. If the output ever lists the oldest version first, or a header field contains a version-shaped token, latestVersion becomes wrong and the update advisory misleads the user. Compare all candidates and keep the greatest one.

Confirm canonicalPath never receives relative paths.

pathApi.resolve uses process.cwd() as the base. When platform is "win32" and the host is POSIX (or the reverse), a relative input resolves against a foreign-format cwd and produces a meaningless canonical path. All current callers pass absolute paths, so this is a robustness note only. Consider returning early or normalizing without resolve when pathApi.isAbsolute(path) is false.

Add a test for the undetermined short-circuit and for the native update environment.

Two behaviors of this cohort have no coverage here:

1. resolveInstallation returns manual-only and skips the npm fallback when an owned definition reports Undetermined, even for a bare command with npm available. This branch decides whether a wrong update command can run, so it needs a focused test. A Scoop shim with an unreadable .shim file plus commands: { npm } reproduces it, and the expected label is "Unknown installation — verification failed".
2. nativeDefinition passes native.environment(executable, context.environment) into update.environment. No test asserts that the resolved installation carries that environment.

The run stub at line 54 ignores its environment argument. Capture it if you assert environment propagation.

As per coding guidelines: "Backend behavior changes must include focused tests for that behavior".

Avoid the implicit "codex" executable-name default.

The fallback chain resolves executableName to "codex" for every provider that is not claudeAgent or opencode. All three drivers pass executableName explicitly today, so this branch only serves other providers, including future Cursor and Grok adapters and the test fixtures. A wrong executable name feeds makeProviderInstallationCatalog and can produce incorrect detection instead of a clear failure.

Make executableName required on ProviderMaintenanceDefinition, or derive it from packageName instead of a hard-coded provider name.

The coding guidelines require an explicit decision for every provider adapter: "Provider-shaped features require an explicit decision for every provider adapter: Codex, Claude, Cursor, Grok, and OpenCode, including an explicit unsupported decision where necessary."

Both new tests set identityKey on the stored and refreshed capabilities.

Thanks for digging into this — you found the right root cause (T3 resolving one install and updating another) and the npm --prefix pinning plus Homebrew formula/cask detection were the correct fixes for #5629/#6245/#7730.

I've opened #9325 which carries those pieces (and the per-instance settings state) onto current main and closes the same three issues. I didn't push here because the branch is 61 commits behind and the changes are structural rather than a rebase. Two things I couldn't land as-is:

• Native installs (~/.local/bin/claude, standalone Codex, ~/.opencode/bin) set latestVersion: null, which drops them to unknown and removes the launch toast for the default install path. Native and npm share a version train, so fix(server): only run provider updates through the installer that owns the binary #9325 keeps the registry as the latest source there and only lets Homebrew override it.
• The Vite+ detector runs vp root -g, which isn't a vp subcommand (exit 2), so it always falls through to npm.

Scoop and WinGet support look useful but need their own issue and someone on Windows to validate; the identity hashing, wrapper-script parsing, and three-way re-resolution in the runner I simplified to a single fresh read under the lock. Happy to review a follow-up for the Windows managers if you want to split them out.

Thanks, happy to take the Scoop/WinGet follow-up and validate it on Windows!
