Some checks were skipped
public bin cache / build + push to preem:grid (push) Has been skipped
ci: run nothing but a main-only bin-cache push on the public forge
Guards internal-only jobs (ci.yml, coverage.yml, flake-update.yml) with
`vars.PUBLIC_CACHE != 'true'` and adds public-cache.yml, guarded to the
inverse, to build the deployed closures and push them to the public
attic cache on a push to main.

`PUBLIC_CACHE` is a repo Actions variable, opt-in only on the public
copy: unset here, it leaves internal CI's `!=` guards true so internal
jobs always run. Job-level `if:` cannot see the `github`/`forgejo`
context at all on this runner (confirmed empirically — a
`github.server_url` comparison always evaluates false at job level,
though the identical comparison resolves correctly inside a step),
so `vars.*`, which is available at job level, is the only usable
opt-in signal here.

# Trust property: `on:` is push-to-main only — no `pull_request`, no
# `workflow_dispatch`, no schedule — so this never runs against an
# untrusted diff, and the `PREEM_PUSH_TOKEN` secret never reaches a PR
# run. The job also gates on the `PUBLIC_FORGE` repo variable, an
# opt-in only the public copy sets — job-level `if:` can't see the
# `github`/`forgejo` context on this runner (confirmed empirically),
# so origin/URL comparisons aren't usable here; `vars.*` is. Internal
# CI's own jobs gate on the inverse, so if this variable is ever unset
# or misconfigured, internal CI keeps running (fail toward "still
# tests", not "silently skips").
