Greptile SummaryThe PR preserves backend identity from installed-tool metadata when a same-named plugin is discovered, while retaining plugin discovery as a fallback when metadata is absent.

Test the installed-tool fallback path.
Lines 749-750 create no existing InstallStateTool. This only tests plugin-only entry creation. It does not test an installed tool with full: None.
Create an installed tool with versions and installs_path, set full to None, and verify that merging sets full without replacing the installed fields. Run mise run test:unit after the test change. As per coding guidelines, use mise run test:unit to execute unit tests.

Heads-up: this appears to have broken Bisected, building and running
Mechanism. The install-dir scan populates short = "dummy"
full = "core:dummy"
explicit_backend = true
So the two cases are harder to separate than "installed metadata wins": here the installed metadata is the wrong one, and the plugin identity was the correct one. Why the new tests don't catch it. I have no strong opinion on the right fix — whether to prefer the plugin identity when the recorded backend doesn't resolve, or to stop writing AI-assisted — Tool: Claude Code; model: anthropic/claude-opus-5; version: 2.1.232. |
## Summary - preserve a failure from either e2e tranche in each paired retry command - continue running the second tranche even when the first one fails - prevent subsequent successful tranches from masking earlier failures ## Root cause Each retry command runs two tranches sequentially but previously returned only the second command's exit status. On #12010, `cli/test_where` failed in the first tranche of its pair and the succeeding second tranche made the overall e2e job pass. ## Stack - stack #12031 - depends on #12030 ## Validation - `actionlint .github/workflows/test.yml` - `mise run lint-fix` *AI-assisted — Tool: Codex; model: OpenAI/GPT-5; version: unavailable.* <!-- CURSOR_SUMMARY --> --- > [!NOTE] > **Low Risk** > CI workflow shell logic only; no application or runtime behavior changes. > > **Overview** > Fixes paired e2e retry steps so a failure in **either** tranche fails the job, instead of only reflecting the second command’s exit code. > > Each retry block now tracks `e2e_status`, runs both `./e2e/run_all_tests` invocations with `|| e2e_status=$?` so the second tranche still runs after the first fails, then exits with the accumulated status.

Resolved by #12029 — confirming so nobody re-chases this: |
Summary
Root cause
Plugin discovery unconditionally replaced the backend recorded in
.mise.backend.toml. When a GitHub-backed tool shared a shorthand with an installed asdf plugin, mise interpreted the existing install through the plugin and could add<install>/bintoPATHinstead of the install root.Related: #12005
Validation
cargo test --bin mise toolset::install_state::tests::plugin_discoverycargo fmt --all -- --checkhk run fix --safe(cargo-fmt,cargo-check --all-features)AI-assisted — Tool: Codex; model: OpenAI/GPT-5; version: unavailable.
Note
Medium Risk
Changes install-state backend resolution used for PATH and backend selection; behavior is narrowed to fix incorrect overwrites, with targeted tests.
Overview
Fixes a bug where plugin discovery overwrote the backend identity already loaded from installed tool metadata (
.mise.backend.toml/ manifest). A GitHub-backed install that shared a shorthand with an asdf plugin could be treated as the plugin backend, which led to wrong PATH layout (e.g.<install>/binvs install root).Plugin merging is moved into
merge_plugin_tools, which only setstool.fullwhen it is still missing (get_or_insert), so on-disk metadata wins and plugin IDs remain a fallback for tools without installed metadata. Regression tests cover both precedence paths.Reviewed by Cursor Bugbot for commit f45dc94. Bugbot is set up for automated code reviews on this repo. Configure here.
