Review comments at @README.md:
- Line 146: Update both README examples that reference jdx/mise-action to use
the tag for the release containing cache_mode, which is v5 at this revision; do
not use v4 for that release.
Review comments at @src/index.ts:
- Line 1475: Update the `hasExplicitMiseDataDir` check so it distinguishes a
caller-provided `MISE_DATA_DIR` override from the value exported by an earlier
action invocation. For action-managed values, assign an isolated data directory
for each invocation so a second verified-downloads action can proceed without
reusing the first installation.
- Line 1475: Update the verified-downloads check using hasExplicitMiseDataDir to
also detect MISE_INSTALLS_DIR and MISE_INSTALL_STORE_DIR overrides, rejecting
the job when either points to a restored tree or isolating those install paths
before installation.

Thanks for the careful work here, and for chasing down the bot findings. I don't think we should add a second cache mode, because the reason for it doesn't hold up. As I understand it, the aim is for zizmor's I agree with that guidance, and I don't want to suggest a cache-backed path for releases. mise's download store only catches a tampered file when a checksum is pinned, and without one a writable cache is trusted. The README notes that not every artifact has a checksum. Release jobs should set For non-release workflows, the So I'm going to close this one. The AI-assisted — Tool: Claude Code; model: anthropic/claude-sonnet-5-5; version: 2.1.295. |
Summary
cache_mode: verified-downloads.mise install --lockedsupport in verified-downloads mode; cache only mise's download CAS and use a fresh data directory.This builds on mise's download CAS. The explicit mode is also intended to let cache-poisoning linters distinguish this path from restored installed-tool trees.

Its cache-key prefix now defaults to an empty value; verified-downloads uses a mode-specific prefix.
