fix(provider-core): mise updates a tool configured by its backend name - #36472
The brief listed nothing to change, so the branch is still 2aa6116. Watched PR #36472 until it settled: all 36 checks passed on 2aa6116. Macroscope approved it with no comments on lines. CodeRabbit raised no code findings and no comments on lines; its only failed check is about the PR description: the Evidence section says the before/after real-app results are 'being captured'. That is the proof and PR steps' job, not a code change, and this step does not edit PR descriptions. The fix itself is unchanged: when T3 finds that mise owns an upgradable install, it runs mise ls --json --installed and upgrades by the tool name whose installs include the owning install's path (e.g. npm:@openai/codex). If nothing matches, it falls back to the driver's short name.
Commit e4f066d (origin/main). Ran mise 2026.11.8 (linux-x64) with isolated MISE_DATA_DIR/MISE_CONFIG_DIR, mise install npm:@openai/codex@0.160.0, global config "npm:@openai/codex" = "latest". Confirmed: mise which codex -> .../installs/npm-openai-codex/latest/node_modules/.bin/codex; mise ls --json --installed codex -> the npm-openai-codex install, active, requested_version latest; mise latest codex -> 0.167.2; mise outdated lists npm:@openai/codex 0.160.0 -> 0.167.2; mise upgrade codex --dry-run -> 'All tools are up to date' (exit 0); mise upgrade npm:@openai/codex --dry-run -> 'Would install npm:@openai/codex@0.167.2'. Then started T3CODE_DEV_SEED=0 vp run dev with mise shims first on PATH, paired headless Chromium (Playwright), opened Settings -> Providers: Codex v0.160.0 with an Update button. Clicked Update: the server ran mise upgrade codex, Codex stayed v0.160.0 (mise ls confirms), and a toast said 'Provider update failed · Codex: Update command completed, but T3 Code still detects an outdated provider version.' On current main the post-update recheck turns the reporter's false 'success' into this error toast, but the update still targets the wrong tool name and can never succeed. Added a row to the existing 'upgrades the mapped mise tool through $name requested as latest' table: a shim to an install configured as npm:package-tool. It fails on main with args ['upgrade','package-tool'] instead of ['upgrade','npm:package-tool']; the other three rows pass.
Evidence
Install Codex 0.160.0 through mise's npm backend, configure "npm:@openai/codex" = "latest", then open Settings → Providers → Codex update details and click Update now. Linux x64, mise 2026.11.8, Chromium 1280×800, light theme, fresh synthetic app state on both commits.
Nothing re-run this round (no code change). PR CI on 2aa6116: all 36 checks passed. From the earlier round: vp test run src/server/maintenanceResolver.test.ts, 114 passed; vp run check:changed, all passed.
Not in this change
The probes mise which, mise ls --installed <tool> and mise latest still use the short name; mise resolves those correctly for backend-configured tools, so I left them unchanged.
CodeRabbit's description check: the PR's Evidence section needs before/after results from the running app, which is the proof step's job.

Reproduces #36470: Codex configured in mise as npm:@openai/codex is
upgraded with `mise upgrade codex`, which mise treats as up to date.

`mise upgrade codex` skips Codex configured as npm:@openai/codex and
exits 0, so the update did nothing. Upgrade by the tool name the full
`mise ls --json --installed` listing gives the owning install.
Fixes#36470

Macroscope's review found this PR approvable — Mise upgrades now use the configured backend-qualified tool name matched to the existing installation, falling back to the previous short name. Existing installation-ownership and upgrade-eligibility safeguards remain intact.
You can add or adjust custom eligibility rules. Learn more.
The mise maintenance resolver now matches the selected install path to an installed tool name and uses that name for mise upgrade. Tests cover installs configured with a backend-qualified name.
Changes: Mise maintenance
Layer / File(s)
Summary
Resolve the upgrade target packages/provider-core/src/server/maintenanceResolver.ts, packages/provider-core/src/server/maintenanceResolver.test.ts
The resolver uses the name of the installed mise tool whose install list contains the selected install path. If it finds no match, it uses the mapped tool name. Tests add backend-aware fixtures and verify the upgrade target for a backend-qualified install.
This change makes mise-based provider updates target the tool's configured backend name, and falls back to the old behavior when no match is found. No merge-blocking risk was identified.

Explanation
The title names the fix (mise upgrading a tool configured by its backend name) and matches the main change in resolveMiseProviderMaintenance, which now upgrades by the backend-qualified listing key. It is specific and follows the conventional commit style used in the repository template.
Full details: Linked Issues check
Explanation
Issue #36470 requires the mise provider update to target the configured tool name (for example npm:@openai/codex), not the driver short name codex, which mise skips for backend-configured installs. The reviewed diff in packages/provider-core/src/server/maintenanceResolver.ts (around line 657) runs mise ls --json --installed after the upgradable decision, decodes the output with decodeMiseInstalls, and selects the listing key whose installs include the owning install.install_path. The update args become ["upgrade", configuredTool], falling back to miseTool when no key matches. This addresses the issue's stated likely fix. The probes mise which, mise ls --installed <tool>, and mise latest are unchanged, and the issue does not require changing them. The PR description reports a unit test row for a shim to an install configured as npm:package-tool, which fails on main and passes with the fix, plus real mise dry-run evidence. The Claude driver short-name pattern is mentioned in the issue as possibly affected; the PR does not address it, but the issue states this only as a possibility, not as a requirement. I did not re-open the decodeMiseInstalls definition in this review, so its exact return shape rests on the existing code path and the PR description.
Full details: Out of Scope Changes check
Explanation
The reviewed whole-PR change to maintenanceResolver.ts only alters the mise upgrade tool-name selection, using the existing listing decoder. The test changes in maintenanceResolver.test.ts add a backend-configured case and fixture support for that case, which directly supports the fix. No unrelated files or behavior changes appear in the reviewed summary. The PR's explicit non-goal (leaving the probes unchanged) matches the code.
Full details: Description check
Explanation
The description follows the repository template's main sections (Problem, Change, Scope, Verification) and gives a reproduction on main, a root-cause explanation, a linked issue (#36470), and a test description. It is thorough. The Evidence section is incomplete, though: it says the before/after app results are 'being captured', and the Evidence table links real screenshots and a recording. The author notes that the fix was not checked in the running app in the PR objectives, but the description itself includes before/after results from the running app, so the claim is partly contradictory. The Verification section states that nothing was re-run this round and cites earlier results (114 tests passed, check:changed passed) with PR CI results. It does not state the mise version used for the earlier round consistently with the objectives (2026.11.7 vs 2026.11.8). The description also includes a non-template 'Who did the work' section, and a note about the description check itself, which is not needed. Overall the description is mostly complete with a few inconsistencies.
