Problem

Git tags were always read from api.github.com, with no mirror in between. That covers the 32 aqua packages with version_source: github_tag (tomcat, ant, aws-cli, blender, …), ubi's tag listing for repositories without releases, and go's dated tag list. Without a GitHub token, ls-remote, latest, install, exec and lock for those tools spend the 60-requests-an-hour budget, and fail once it's gone:

$ MISE_DEBUG=1 mise latest aqua:apache/tomcat@10
DEBUG GET https://api.github.com/repos/apache/tomcat/tags?per_page=100
DEBUG GET https://api.github.com/repos/apache/tomcat/tags?per_page=100 403 Forbidden

Change

Tags now come from mise-versions' tags endpoint (/api/github/repos/{owner}/{repo}/tags?page=N, jdx/mise-versions#369), on the same terms as release lists in #14460:

  • Without MISE_LIST_ALL_VERSIONS mise reads the first page, as it did from GitHub. With it, mise reads every page mise-versions serves (up to 10).
  • go's dated listing asks for dates=1, which replaces one GitHub request per tag with the dates mise-versions includes.
  • A mise-versions failure is an error naming mise-versions and use_versions_host = false. GitHub is asked only for a repository mise-versions doesn't list, and only with a token (a private repository).

use_versions_host = false, url_replacements for GitHub and custom api_urls still read tags from the API directly.

Merge order

Stacked on #14460, which adds the mirror-only rules this reuses. The tags endpoint is live on mise-versions:

$ MISE_DEBUG=1 mise latest aqua:apache/tomcat@10   # no GitHub token
DEBUG GET https://mise-versions.jdx.dev/api/github/repos/apache/tomcat/tags?page=1
10.1.61

Validation

  • Unit tests cover the response shape from feat(github): mirror GitHub tag lists mise-versions#369, single-page vs. all-pages listing, a 404 on the first page vs. a later one, and the page limit.
  • backend/test_github_api_not_used now also runs mise latest aqua:apache/tomcat@10 with no token, and fails on any api.github.com request. It passes locally against the live endpoint.

Note

Medium Risk
Changes version resolution for many aqua/ubi/go tag-based tools and adds mirror pagination/error semantics; misconfiguration or mirror gaps could affect installs, though behavior mirrors the already-shipped release mirror path.

Overview
Public GitHub tag lists now come from mise-versions (same rules as mirrored releases), so tools that resolve versions from git tags—e.g. aqua github_tag packages like apache/ant—no longer burn unauthenticated api.github.com quota.

list_tags, list_tags_from_url, and dated tag listing call the new /api/github/repos/.../tags endpoint with pagination capped like releases; optional dates=1 avoids per-tag commit fetches on GitHub. Tag caches use source-aware keys and cached_or_stale, so temporary mise-versions outages can fall back to an older cached list. url_replacements on the tags URL still bypass the mirror; GitHub is only used when the mirror returns 404 on the first page and credentials are present (private repo path).

Docs and e2e cover tag-based latest without GitHub API traffic and tag URL replacement routing.

Summary by CodeRabbit

  • New Features
    • Eligible public GitHub tag listings can use mirrored metadata, including dates when requested. By default, listings include the first page; listing all versions follows additional pages up to the host’s limit.
  • Compatibility
    • Configured URL replacements continue to route tag requests instead of using mirrored metadata.
  • Reliability
    • If the first mirrored page is unavailable, GitHub fallback is limited to private-repository lookups. If a later page is unavailable, listing all versions returns an error.
  • Documentation
    • Clarified that public GitHub tags, as well as release data, come from mise-versions when enabled.

GitHub release lists and releases come from mise-versions whenever it
applies. A failure there is now an error naming mise-versions and
`use_versions_host = false`, not a retry against api.github.com. A 404 goes
to GitHub only for a repository mise-versions doesn't list, and only with a
token (a private repository). Releases without assets are accepted from
mise-versions, replacing the 24h "skip mise-versions" cache for them.

📝 Walkthrough

GitHub tag listings use paginated mise-versions metadata when the repository is mirrored and its public GitHub API URL is not replaced. Listing paths retain direct API behavior when mirroring is unavailable or returns no listing.

Changes: GitHub tag mirroring

Layer / File(s) Summary
Mirrored tag endpoint
crates/mise-util/src/versions_host.rs
Adds tag-page and tag metadata types, paginated fetching, next-page validation, and request logging. Tests cover tag URL generation and page deserialization.
Tag listing integration
crates/mise-util/src/github.rs, crates/mise-util/src/github/tests/mirrored_releases.rs, e2e/backend/test_github_api_not_used, e2e/backend/test_github_tags_url_replacements, settings.toml
Uses mirrored tag pages when eligible and updates tag cache keys to include the API URL, repository, and mirror-source status. Pagination follows subsequent pages only for list_all and stops at the configured limit. A missing first page returns no listing; a missing later page errors. Tests cover pagination and URL replacement behavior. The settings documentation includes public repository tags among data served by mise-versions.

<!-- entire-trail-link-end -->

## Problem

Installing a packslip tool that declares a skill living in its
repository (fnox, usage, and others) listed the skill's directory and
downloaded every file through `api.github.com`'s contents API. That's at
least two requests per install against the 60-an-hour budget users
without a token get. Once that budget ran out, the install failed:

```console
$ mise install fnox@1.39.0
WARN  fnox@1.39.0: could not fetch skill skills/fnox from the source repository: HTTP status client error (403 Forbidden) for url (https://api.github.com/repos/jdx/fnox/contents/skills/fnox/SKILL.md?ref=cc06c75…)
mise ERROR Failed to install packslip:github.com/jdx/fnox@latest: fnox@1.39.0: declared skill(s) fnox are not installed
```

## Change

- **Skills from the source repository:** the directory listing comes
from mise-versions
(`/api/github/repos/{o}/{r}/contents/{path}?ref={commit}`). The listing
is pinned to the commit, so mise-versions can cache it for good. The
files come from `raw.githubusercontent.com/{o}/{r}/{commit}/{path}`,
which isn't API-rate-limited.
- **A `url_replacements` rule** for a repository's contents API
(`https://api.github.com/repos/{o}/{r}/contents`) is the source of its
skill listings, as it was before.
- **Private repositories:** mise-versions doesn't know them, so they are
still listed and fetched through the contents API with the user's token.
Without a token the error says to set one, or to set `use_versions_host
= false`.

Repository identity lookups (`repository_identity` / `canonical_repo`)
stay on GitHub on purpose. They decide whether a renamed repository's
attestations or packslip are trusted, and an answer from a mirror could
vouch for any repository. Only renamed or transferred repositories reach
them.

As in #14460, a mise-versions failure is reported as an error rather
than retried against GitHub. `use_versions_host = false` and
`url_replacements` for GitHub still use the API directly.

## Merge order

Stacked on #14460. It needs mise-versions to serve the `contents`
endpoint first. Until then mise-versions answers 404, which this PR
reads as "private repository" and turns into an error without a token.
I'll confirm it with curl before marking this ready.

## Validation

- `backend/test_github_api_not_used` now also runs `mise use
fnox@1.39.0` with no token and checks `mise skills ls`. It fails on any
`api.github.com` request. It can only pass once the endpoints are live.
- New e2e `backend/test_packslip_skill_url_replacements` checks that a
contents `url_replacements` rule is used instead of mise-versions.
- Unit tests cover the response shape and the URL encoding of contents
paths.
- `test_plugins_packslip_forge`, `test_plugins_packslip_unprefixed` and
`test_packslip_resources` pass. The first two use `url_replacements`,
which keeps the direct-API path.

starts from a fresh cache. The tag URL checked against url_replacements is

… replacements

A mise-versions 404 for a skill directory reaches GitHub only when
mise-versions doesn't list the repository at all, as for release tags. A
direct listing with an entry mise can't read is an error rather than a
silently shorter directory. A url_replacements rule for one skill file's
contents URL is used for that file.

A rule for `.../releases?per_page=100` now counts as rerouting the
repository, both for choosing the source and for the cache key. The

mise-versions' 404, so it no longer depends on the runner's token.

Per jdx/mise-versions' client contract, a 429, 5xx or connection failure
from mise-versions serves the release list or release mise cached
earlier, however old, instead of failing; a 403 (mirror disabled or
restricted) still reports the error. Neither ever reaches api.github.com.

## Problem

Listing a GitHub-hosted tool's versions meant paging through its
releases or tags, 100 at a time. That took several requests per tool,
and the mise-versions paged endpoints stop at 10 pages, so the oldest
versions of repositories like zed-industries/zed (14 pages) and
openai/codex weren't listed at all. The paged endpoints also run
mise-versions' Worker on every request.

aqua's `latest` for packages whose GitHub releases carry no assets
(kubectl, terraform, vault) needs GitHub's "latest" mark. mise-versions
doesn't serve asset-less releases, so `latest` fell back to the newest
listed version. And aqua sent kubectl's lookups straight to
`api.github.com`, because the package reads `kubernetes/kubernetes`, not
a repository named like its id:

```console
$ MISE_DEBUG=1 mise latest aqua:kubernetes/kubectl   # no token
DEBUG GET https://api.github.com/repos/kubernetes/kubernetes/releases/latest
```

## Change

mise-versions now publishes each public repository's whole release and
tag list as a static file (jdx/mise-versions#370):
`/data/github/{owner}/{repo}/releases.json`, `tags.json`, and
`assets/{asset}/releases.json`. It lists up to 2,000 entries, newest
first in GitHub's order. mise reads these first:

- **`github:` tools** (`ls-remote`, `latest`, `outdated`, `upgrade`)
list versions from `releases.json`. Releases without assets are still
dropped unless the tool has a `url`.
- **aqua packages:** release-based ones read `releases.json`, and
`version_source: github_tag` ones read `tags.json`. So do ubi's tag
listing and go's dated tag listing.
- **packslip vendors** read `assets/<bundle>/releases.json`, the
releases that carry a packslip bundle.
- **aqua's `latest`:** when GitHub's "latest" mark can't be read (a
release without assets), it comes from the newest stable release in
`releases.json`, as long as mise-versions read that list from GitHub
within the last 7 hours (its documented refresh interval for quiet
repositories, plus a deploy). GitHub's own mark is still used whenever
it can be read.
- **aqua asks mise-versions for every public repository a package
reads**, not only one named like the package. kubectl's
`kubernetes/kubernetes`, a checksum file or a signer in another
repository all count. Release data from mise-versions is pinned to the
repository asked for, and downloads and attestations are verified, so
that restriction protected nothing.

```console
$ MISE_DEBUG=1 mise ls-remote github:cli/cli
DEBUG GET https://mise-versions.jdx.dev/data/github/cli/cli/releases.json
$ MISE_DEBUG=1 mise latest aqua:kubernetes/kubectl   # no token
DEBUG GET https://mise-versions.jdx.dev/data/github/kubernetes/kubernetes/releases.json
1.37.1
```

**When the whole list can't be used** (an error, a 404 for a repository
mise-versions doesn't know, or a list marked `truncated` because it's
still being crawled or is longer than the crawl allows), mise falls back
to the paged mise-versions endpoints, never to GitHub. Those keep the
rules from #14460: GitHub only for an unknown repository, and only with
credentials. **Callers that need asset names** (picking a download,
packslip's bundle lookup, build revisions) still read full releases.

## Merge order

Stacked on #14461 (tags through mise-versions), which is stacked on
#14460. All three endpoints this uses are live:

```bash
curl https://mise-versions.jdx.dev/data/github/cli/cli/releases.json
```

## Validation

- New e2e test `backend/test_github_whole_release_list` checks that
`ls-remote github:cli/cli` reads `releases.json` and doesn't page.
- `backend/test_github_api_not_used` gains `latest
aqua:kubernetes/kubectl` with no token.
- Unit tests cover the list URLs (lowercased, invalid names and assets
rejected) and the response shapes from jdx/mise-versions'
`docs/github-versions.md`.
- Traced with no token: `latest aqua:hashicorp/terraform` → 1.16.5,
`aqua:hashicorp/vault` → 2.1.2, `aqua:kubernetes/kubectl` → 1.37.1, and
`install aqua:kubernetes/kubectl@1.31.0`. None of them made a request to
`api.github.com`.
- `test_aqua_version_listing_fetch_failure`,
`test_aqua_github_attestations` and `test_lockfile_provenance` pass.
- `test_github_api_not_used` and `test_packslip` still fail on this
branch, as they do on #14460's branch. Installing a packslip tool that
declares a skill in its repository (packslip, fnox) needs mise-versions
to serve directory listings, which isn't deployed yet.

> [!NOTE]
> **Medium Risk**
> Changes how remote versions and aqua `latest` are resolved across
github, aqua, and packslip; mis-trusted or stale whole lists could
affect version picks until fallback or cache refresh, though
attestations and downloads remain verified separately.
> 
> **Overview**
> Version listing for GitHub-backed tools now prefers **mise-versions’
static whole-list JSON** (`releases.json`, `tags.json`, and per-asset
`releases.json`) in a single request, with a new lightweight
**`ReleaseVersion`** type and cached **`list_release_versions`** /
**`list_release_versions_with_asset`** APIs. Truncated, undated, or
failed whole lists still fall back to the existing paged mise-versions
endpoints—not `api.github.com`.
> 
> **`github:`**, **aqua** (release dates), and **packslip** vendors are
wired to these paths; tag listing also tries whole `tags.json` when
every tag has a date.
> 
> For **aqua `latest`**, a 404 on GitHub’s “latest” release (common when
releases have no assets) can use the **newest stable entry** from a
fresh whole release list (7h `fetched_at` window). Aqua now uses
mise-versions for **any public repo** a package references (e.g.
`kubernetes/kubernetes` for kubectl), including attestations—not only
repos named like the package id.
> 
> E2e coverage adds whole-list `ls-remote` for `github:cli/cli` and
`latest aqua:kubernetes/kubectl` without hitting the GitHub API.

## Summary by CodeRabbit

* **Performance**
* GitHub release and tag listings can use mirrored metadata, reducing
reliance on paginated requests.
* Version checks use compact release details, including asset
availability, to identify eligible versions.
* Listings for releases containing a specific asset can use mirrored
metadata as well.

* **Bug Fixes**
* Latest-release lookup can fall back to the newest stable release when
the marked release is unavailable.
* Incomplete or outdated mirrored data falls back to paginated results;
dated listings use paginated results when mirrored entries lack dates.

Instruction counts

Nothing was compared, and so nothing was gated. No series appears on both sides: either the base has no measurements recorded, or the two were measured on different runner classes, which are deliberately not comparable — counts shift between machine types by more than a real regression does.

New, nothing to compare against: env on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, hook-env on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, ls on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, registry on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143, startup on jdx-perf-v1-ubuntu24.04-x64-mise-rust1.97.1-img5263c143

Only instruction counts gate. Wall clock is shown for context — on identical hardware it moves 4-20% run to run.

Measured by tak — instruction-counted CLI benchmarks, stored in this repository's git notes.

## Problem

mise reads public GitHub metadata (release lists, single releases and
`latest`, tags, repository contents for packslip skills, attestations,
the checksum-mismatch hint, and `mise self-update`'s release) from
[mise-versions](https://mise-versions.jdx.dev). Since #14460, #14461 and
#14469 it never asked `api.github.com` instead, so a mise-versions
outage failed installs outright, even for users with a `GITHUB_TOKEN`
who could have asked GitHub. The only way out was turning
`use_versions_host` off.

## Change

mise-versions stays the first source, but when it **errors** (a timeout,
a lost connection, a `429`, or any `5xx`), mise now retries the same
lookup on `api.github.com`, with the user's GitHub token if one is set.
Anything mise-versions *answers* is still trusted and never reaches
GitHub: a `404` (a missing release, tag or repository), an empty list, a
`403` (the mirror disabled), and an answer that fails mise's checks. So
normal usage still doesn't spend GitHub's 60 anonymous requests an hour.

With mise-versions answering `503` and a valid token, `mise ls-remote
github:jdx/communique` now lists the versions from GitHub. With a
rejected token, both failures are reported:

```text
Error:
   0: failed to read GitHub releases of jdx/communique from mise-versions.jdx.dev (HTTP status server error (503 Service Unavailable)), and from api.github.com after it
   1: HTTP status client error (401 Unauthorized) for url (https://api.github.com/repos/jdx/communique/releases?per_page=100)
      github auth: yes (token from MISE_GITHUB_TOKEN)
```

GitHub's error stays in the chain, so the "no GitHub token was found"
rate-limit hint still appears, and a version list cached earlier still
stands in when both sources fail.

**Attestations** follow the same rule. A failed mise-versions
attestation lookup, or a failed repository listing after an attestation
`404`, is retried on GitHub's attestation API, and
[`provenance_api_failures_fatal`](https://mise.jdx.dev/configuration/settings.html#provenance_api_failures_fatal)
applies to GitHub's answer. Nothing else about attestations changes:
bundles are still verified against Sigstore's own trust root,
attestations made by another repository are still rejected, the
predicate filter still reads the signed payload, and paranoid mode works
as before.

`use_versions_host = false`, `url_replacements` for GitHub, GitHub
Enterprise or other custom API URLs, and private repositories with a
token still go to their API directly, as before.

## Implementation

One helper, `github::mirror_or_github`, makes the decision for every
call site, using `versions_host::retries_on_github` to classify the
mirror's failure. Attestations, which return verdicts rather than
results, use the same classifier through a new `RetryGithub` verdict.
The `use_versions_host` docs, the GitHub tokens, errors, paranoid and
github backend pages, and the error messages that said mise asks
mise-versions "instead of api.github.com" are updated.

The matching client contract change in mise-versions'
`docs/github-versions.md` is jdx/mise-versions#381.

## Validation

- New unit tests for the helper: no connection, `429` and each `5xx` go
to GitHub; a hit, a `404`, an empty answer, a `403`, another `4xx` and a
bad answer don't; a failed retry names both failures, keeps GitHub's
`403` text for the rate-limit hint, and still allows the stale cache.
Attestation verdict tests cover retriable and non-retriable listing
failures and the combined error, which stays an API failure.
- `e2e/backend/test_github_api_not_used` still asserts no
`api.github.com` requests while mise-versions is healthy, and now also
points mise-versions at a local server: on `503` mise asks
`api.github.com`, and on `404` it does not.
- `test_aqua_github_attestations`, `test_github_registry_attestations`
and the `test_lockfile_provenance*` tests pass; clippy and the 1.95 MSRV
check are clean.

## Summary by CodeRabbit

* **New Features**
* GitHub release, tag, repository, and attestation lookups now retry
through GitHub when mise-versions encounters a timeout, connection
failure, HTTP 429, or HTTP 5xx response. Not-found responses and other
authoritative answers are used directly.
  * If both sources fail, the error reports both failures.

* **Documentation**
* Updated settings and guidance to describe fallback behavior, including
for attestation checks.
