  wings_enabled:
    description: |
      [experimental] Opt in to the mise-wings asset cache
      (https://mise-wings.en.dev) for this action invocation.

      When `true`, the action exports `MISE_WINGS_ENABLED=1` so
      the installed mise binary routes tool-install URLs (npm
      tarballs, GitHub release artifacts) through the per-org
      wings cache subdomains.

      Authentication is automatic via the runner's GitHub OIDC
      identity — no `mise wings login` step, no long-lived
      secret to rotate. The workflow must declare
      `permissions: id-token: write` so the OIDC token-issuer
      env vars are populated; without that, mise falls through
      to direct-origin fetches transparently.

      Default `false` is the conservative posture: a workflow
      with `id-token: write` (used for SLSA / AWS-OIDC /
      Sigstore / etc.) should not have its OIDC token sent to
      a third-party cache without explicit opt-in. Older mise
      binaries that don't speak wings ignore the env var
      entirely, so this is forward-compatible.

      Requires an active mise-wings subscription on the Clerk
      org linked to the GitHub org running the workflow;
      without one, the proxy 402s and mise leaves the cache
      off without affecting the workflow's success.
    required: false
    default: "false"
