The server cannot build it (5.3 GiB from scratch; capped, still 2.6-3.3
GiB against ~2.3 GiB free). The heap built here by the same Isabelle2025-2
is a generic package in this repository's registry (45 MB, SHA-256
bb247846...e999cb339e); the Dockerfile fetches it into Isabelle's system
heaps with the checksum pinned, the token a build secret. Portable: a
fresh Isabelle home with only this heap checks StarForth without
rebuilding HOL-Library. FABRIC-3.md XLVII.4.

Measured here (Isabelle2025-2, one thread): HOL-Library from scratch takes
~11 minutes and peaks at ~5.3 GiB -- what nightly 174 was killed doing; the
StarForth session on a built HOL-Library takes under a minute and ~2.2 GiB.
The image builds HOL-Library once into Isabelle's own heaps, so every job
finds it.

Captain Bob, 2026-11-06: a small server, a little sluggish. Each change
cost about an hour of runner time; the gate itself is about 15 minutes.
#119 -- build.yml runs on pushes to the working branch only. What
reaches master arrives through a PR whose content just passed
acceptance; checking it again cost ~23 minutes after every merge.
#120, first step -- ci/runner-image/Dockerfile: gitea/runner-images'
Ubuntu 24.04 (with Node, for the actions) plus what
make ARCH=amd64,aarch64,riscv64 init INIT_DOCS=0 installs -- run from
the Makefile itself, not a copied list -- and Maven for publishing.
.gitea/workflows/runner-image.yml builds it and publishes it to the
package registry as lithosananke-runner:<commit>. The workflows switch
to it in a later change, once it is published and has passed
acceptance. It needs the runner to lend jobs its Docker daemon
(container.docker_host: automount) and a PACKAGES_TOKEN secret, unless
the Actions token may publish packages.
make init does git lfs install --local only inside a checkout: the
image build is not one.
