Several installers let a download host get around a checksum or signature that should have been enforced: either by answering 404, or because the installer preferred the host's own checksum. With this PR, a pinned or published checksum is checked, and a missing signature fails the install instead of being skipped.

What changes

• node
  • A missing SHASUMS256.txt.sig now fails mise install and mise lock instead of skipping GPG verification. The unofficial-builds host, which signs nothing and serves the musl builds, is exempt.
  • mise lock verifies the signature before recording checksums. If verification fails it warns and records the entry without a checksum, so the next install verifies the signature itself.
  • If mise.lock pins the prebuilt archive and the host answers 404, the install fails and points at mise lock node, instead of quietly compiling the source tarball.
• erlang: the checksum mise.lock pins wins over the one builds.hex.pm publishes for the same artifact.
• npm: when a checksum is pinned, the root package in the aube lock graph must match the tarball that passed that checksum.
• spm: when mise.lock pins a bundle checksum for this platform, a missing or altered artifact bundle fails the install instead of falling back to a source build.
• http: the mise.lock checksum is checked before unpacking, as the s3 backend already does.
• bun and deno: installs without a lock entry check the archive against the publisher's sha256.
• GPG: verification work is capped at one attempt per trusted key and subkey, so a .sig file full of bogus signatures can't stall an install.

Compatibility

Node mirrors that don't copy the .sig files, and a few early releases that never had one (for example 4.0.0 and 5.12.0), now need node.gpg_verify = false. The error message says so.

Validation

Each fix has a regression test that fails without it: unit tests, plus 7 new or extended e2e tests. Related node, npm, erlang lockfile and tool-stub e2e tests pass, as do clippy with -D warnings and cargo +1.95 check. Not tested end to end:

• deno, which shares bun's code path;
• the npm call site, which would need a fake registry serving tarballs;
• erlang on macOS and Windows.

Summary by CodeRabbit

• Security
  • Installations now validate downloaded artifacts against published checksums and package integrity data. Checksum mismatches stop installation before files are installed.
  • Node.js installs and lockfile updates now require valid release signatures, except for unsigned unofficial builds.
• Lockfiles
  • Bun and Deno checksums are recorded per platform. SwiftPM artifact-bundle checksums are recorded and enforced during installation.
  • Locked Node.js or SwiftPM artifacts that are unavailable or fail verification no longer fall back to source builds.
• Documentation
  • Updated guidance explains checksum recording, signature requirements, and installation fallback behavior.

📝 Walkthrough

The changes enforce checksum and signature checks during installation and lock resolution. They also preserve pinned checksum data, prevent fallback when locked artifacts are unavailable, and limit detached-signature content reads.

Changes: Artifact integrity and lock handling

Layer / File(s)	Summary
Bound detached-signature reads crates/mise-util/src/gpg.rs	Detached-signature verification allows one signed-content read per trusted primary key and subkey. Tests cover repeated issuer-less signatures and signatures naming trusted keys.
Verify HTTP artifacts and preserve checksum pins src/backend/http.rs, src/plugins/core/erlang.rs, e2e/backend/test_http_lock_checksum_before_install, e2e/core/test_erlang_lockfile	HTTP checksum verification now occurs before cache planning and extraction. Erlang keeps an existing checksum for an unchanged artifact. Tests check checksum failures and pin preservation.
Record Bun and Deno checksums src/plugins/core/bun.rs, src/plugins/core/deno.rs, e2e/core/test_bun_published_checksum, docs/lang/bun.md, docs/lang/deno.md	Bun and Deno downloads populate missing platform checksum metadata from published checksum sources. The Bun test checks that a mismatch fails installation.
Validate npm archive integrity src/backend/npm.rs	npm installation checks archive integrity against the root package entry in an attached Aube dependency graph. Tests cover matching hashes, mismatches, and missing or incorrect package data.
Verify Node.js checksum signatures src/plugins/core/node.rs, e2e/core/test_node_gpg_verify, settings.toml, docs/lang/node.md, docs/security.md, src/plugins/core/swift.rs	Node.js checksum resolution verifies signatures when configured. Missing signatures fail except for unofficial-builds. Tests and documentation cover installation and lock resolution.
Keep locked Node.js installs on the pinned binary src/plugins/core/node.rs, e2e/lockfile/test_lockfile_node_pinned_binary_not_found	A missing precompiled archive fails when the lock entry pins that binary. Tests verify that locked installation does not compile from source, while installation without the lockfile can do so.
Enforce locked SwiftPM artifact bundles src/backend/spm.rs, e2e/backend/test_spm_locked_artifactbundle, docs/dev-tools/backends/spm.md, docs/dev-tools/mise-lock.md	A locked artifact-bundle checksum prevents source-build fallback when a bundle is missing or fails checksum verification. Tests cover checksum recording, failure cases, and a successful locked install.

Merge Risk: 🟡 Moderate · up to 207ae

A SwiftPM install pinned to a locked artifact bundle can still build from source when the bundle has no binary for the local Swift target. That bypasses the new pinned-bundle enforcement. Fix the locked fallback before merging. The lockfile documentation also needs a small wording correction.

[High impact] The PR appears safe to merge; no new blocking issue remains.

Summary

This PR makes installers honor pinned checksums and requires Node release signatures. The latest changes close the Swift no-matching-binary fallback and make Bun and Deno reject missing checksum entries and fetch errors other than 404.

• Node installs and lock updates require signatures for official checksum lists.
• A missing locked Node archive stops instead of triggering a source build.
• Bun and Deno installs check publisher checksums when no checksum is pinned.
• Pinned checksums stay authoritative and are checked before downloaded files are unpacked.
• Npm installs require the locked package graph to name the verified archive.
• A locked SwiftPM bundle cannot be replaced by a source build.
• GPG signature checks limit work to one attempt per trusted key and subkey.

- Line 413: Update the URL-exemption rationale in the documentation near the
`spm` row to clarify that `spm` and `core:swift` record URLs for artifact
installs, but locked mode does not require them; keep the artifact-only scope
and npm/PyPI dependency-graph checks accurate.

Review comments at @src/backend/spm.rs:
- Line 309: Update the Ok(false) handling for try_install_artifactbundle in the
caller so artifactbundle_locked also blocks the install_from_source fallback
when no bundle binary matches the target. Preserve the existing
artifactbundle_required behavior.
