When mise can't fetch an aqua tool's version list (GitHub rate limit, network failure, a mirror that is down), a request like 4 resolves to itself, because without the list mise can't tell a version selector from a short exact version. mise then trusted that string:

$ mise lock                                  # tfcmt = "4", listing unreachable
✓ Lockfile written to mise.lock              # exit 0
$ grep version mise.lock
version = "4"

$ mise install aqua:suzuki-shunsuke/tfcmt@4
Error: Failed to install aqua:suzuki-shunsuke/tfcmt@4: error sending request: ... Connection refused

The lockfile got a version that may not exist, and the install error never mentioned that the version list was missing.

mise lock now refuses to record a version that only resolved to its own request string after that tool's listing failed, unless the version is installed:

$ mise lock
Error: cannot lock aqua:suzuki-shunsuke/tfcmt@4: unable to fetch versions for aqua:suzuki-shunsuke/tfcmt: error sending request: ... Connection refused

Versions already in the lockfile are unaffected, because they resolve from the lockfile and don't need the list.

mise install still tries the request as written, since a short exact version can be valid: aqua's nektro/zigmod maps 100 to its r100 tag. When that fails, the error now says the version was never checked against its version list and why:

Error: Failed to install aqua:suzuki-shunsuke/tfcmt@4: error sending request: ... Connection refused
note: aqua:suzuki-shunsuke/tfcmt@4 was not checked against its version list, which could not be fetched: ...

Only backends that record a failed fetch are affected, and today that's aqua.

e2e/backend/test_aqua_version_listing_fetch_failure now also covers install …@4 and mise lock with a prefix selector, with the listing hosts unreachable. The new install check fails without this change. The aqua and lock e2e tests, the unit tests and clippy with -D warnings pass.

Note

Medium Risk
Changes lock and install error paths for aqua tools when version listing fails; incorrect exemptions could block valid locks or still allow bad pins.

Overview
When an aqua tool’s remote version list cannot be fetched, a fuzzy request like "4" can resolve to itself without ever being validated. mise lock no longer writes those strings into the lockfile: it errors with cannot lock … unable to fetch versions unless the version came from the lockfile, is already installed, or was explicitly passed as tool@version on the CLI (still checked the same way).

mise install behavior is unchanged—it still attempts the requested version—but failed installs now append a note that the version was not checked against its version list and include the listing failure cause.

The aqua listing-fetch-failure e2e test now covers prefix installs, config pins, and CLI tool@version overrides under unreachable listing hosts.

Summary by CodeRabbit

• Bug Fixes
  • mise lock now rejects requested versions that cannot be verified against the tool’s available version list, unless the version is already installed or was resolved from the lockfile. CLI tool@version requests are also checked, preventing unverified versions from being recorded as confirmed.
  • Installation failure messages now indicate when a tool version was not checked against its version list, making version-list fetch failures clearer.

📝 Walkthrough

Walkthrough

Install failure messages now include a hint when version listing fails. The lock command checks resolved versions against configured and CLI-requested versions. The e2e test covers install and lock failures, including a CLI version override.

Changes

Version listing failure handling

Layer / File(s)	Summary
Report version-listing failures src/errors.rs	Install failure messages include a note when the backend reports a version-list fetch failure. Multi-failure details use pre-rendered error strings.
Reject unverified lock versions src/cli/lock.rs, e2e/backend/test_aqua_version_listing_fetch_failure	The lock command checks configured and CLI-requested versions when validating resolved versions. The e2e test checks install and lock failures and verifies that version 4 is not written to the lockfile, including when @4 overrides an exact pin.

Confidence Score: 5/5

The PR appears safe to merge; no actionable new issue or outstanding previous finding remains.

Summary

This PR prevents mise lock from persisting versions that merely echoed an unresolved request after version listing failed, while preserving installation attempts for potentially valid short exact versions.

• Rejects unverified lock versions unless they came from an existing lockfile or are installed.
• Adds the recorded listing failure to installation diagnostics.
• Covers configured selectors and CLI version overrides with an Aqua end-to-end test.
• The three previous findings are no longer outstanding; their threads were resolved after the implementation was adjusted.

🟡 Minor · Clear lockfile provenance when a CLI selector changes the version. · lock.rs:42-53

src/cli/lock.rs:42-53
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Clear lockfile provenance when a CLI selector changes the version.

from_lockfile marks the tool as lockfile-resolved. The non-latest CLI override then changes tv.version without clearing that mark. Therefore, when Aqua listing fails and the requested version is not installed, a changed selector such as tool@4 bypasses this guard and can reach lockfile.write, which persists an unverified version. An unchanged selector that equals the locked version must keep the existing-lock exception.

Clear the provenance only when the CLI override changes tv.version.
