Closes #872.

What broke

A Conductor tenant fork could not deploy. Its first run on a Forgejo runner stopped after 22 seconds, at uses: opentofu/setup-opentofu@v2:

unable to clone 'https://data.forgejo.org/opentofu/setup-opentofu' … remote: Not found.

Forgejo resolves a bare uses: against DEFAULT_ACTIONS_URL. The forgejo stack pins that to data.forgejo.org, and data.forgejo.org does not mirror this action.

Change

The six places that used the action (five workflows and nexus-bootstrap) now run .github/scripts/install-opentofu.sh, a plain script that behaves the same on GitHub Actions and on Forgejo.

  • One version, in one place. The script installs the pinned 1.10.0 and refuses any argument. Every workflow therefore gets the same OpenTofu, which tofu-checks.yaml relies on. nexus-bootstrap loses its tofu_version input; no caller passed it.

  • Pinned checksums, not fetched ones. fix(ci): Install OpenTofu without setup-opentofu — it does not resolve on Forgejo #872 proposed downloading SHA256SUMS at run time. That file comes from the same place as the archive, so it would catch a broken download but not a replaced one. The pinned values were taken from tofu_1.10.0_SHA256SUMS after checking that file the way OpenTofu documents:

    • cosign verify-blob with the identity …/release.yml@refs/heads/v1.10 → Verified OK;
    • the same command with a wrong identity → refused;
    • both pinned values compared with freshly downloaded archives → equal.

    The script's header says how to pin the next version.

  • .tar.gz rather than .zip, so tar is enough and unzip is not needed.

  • Reads the version back. The script checks what the installed binary reports before it appends the directory to GITHUB_PATH, which both runners honour.

  • Refuses what it cannot install: non-Linux runners, and architectures with no pinned checksum.

  • tofu-checks.yaml now also triggers on changes to the script, so the real install runs in CI whenever the script changes.

Before switching, I checked every affected job: each one checks the repository out at its root before the install step, which the script needs.

Verified

Run on the deployed server:

Environment Result
Ubuntu 26.04, amd64 OpenTofu v1.10.0 installed; GITHUB_PATH written; a following step with that PATH runs it
node:22-bookworm (the Forgejo runner's job image) the same. The image has curl, tar, gzip and sha256sum
arm64 not run, for lack of a machine. Its pinned checksum matches the real release archive
called with a version argument exit 1

This PR does not verify a full lifecycle run on Forgejo. That is the last acceptance item of #872, and it needs a real Conductor deploy after a release that contains this change.

What data.forgejo.org mirrors

docs/stacks/forgejo-runner.md gets a new section. Every uses: in the repository was checked against data.forgejo.org on 2026-09-16. Tags were checked with git ls-remote; commit-SHA pins were checked by fetching the commit, because ls-remote cannot see a commit.

  • Mirrored: actions/checkout, actions/cache, actions/setup-node, actions/upload-artifact, astral-sh/setup-uv, including the three SHA pins.
  • Not mirrored, CI-only: raven-actions/actionlint, googleapis/release-please-action, codecov/codecov-action, MishaKav/pytest-coverage-comment.

After this change, every uses: in the lifecycle workflows resolves on Forgejo. The docs say this covers action resolution only, not a full run.

Tests

The new file tests/unit/test_install_opentofu.py checks:

  • No uses: of setup-opentofu. It parses the YAML, so the explanatory comments do not count.
  • No call of the script with a version.
  • No job runs tofu before installing it. A local composite action that runs tofu, such as nexus-config-tfvars, counts as a tofu call. A second test makes sure this rule still finds the lifecycle jobs, so it cannot pass by matching nothing.
  • Both checksums are pinned and well-formed.
  • The script's refusals, run under bash with curl and uname replaced: a version argument, a non-Linux runner, an unpinned architecture, and an archive that does not match the pin (for both architectures). In each case nothing is installed and nothing is added to PATH. The requested URL is asserted, so the test is known to have reached the comparison.

The success path cannot be faked against a pinned checksum; tofu-checks.yaml runs it for real.

Seven mutations, each caught:

Mutation Caught by
checksum comparison removed mismatch test, both architectures, which also asserts the message, since the script still fails later on the bad archive
argument check removed argument test
OS check removed non-Linux test
arm64 checksum removed checksum-format test and the arm64 mismatch test
a workflow back on setup-opentofu uses: test and ordering test
a workflow passing a version version test
a workflow with no install ordering test

Local CodeRabbit round

Reviewed 592c9bf2: 1 finding.

install-opentofu.sh (major): move to OpenTofu 1.11.10 or later. Right on substance, not done here; filed as #873.

1.10.0 is affected by GHSA-q7j3-v8qv-22vq (high), and the 1.10 series will not be patched for it. The deploy configuration declares no modules, so it does not reach the advisory. tofu-checks.yaml does reach it, because it runs tofu init on configuration from pull requests.

It is not part of this PR because a version change also changes which OpenTofu writes the real state in R2, and that needs a spin-up to verify. This PR changes only how OpenTofu is installed, and the 1.10.0 pin predates it. With this change in place, the move is three lines in one file. #873 has the advisories, the exposure and the decisions to make.

Release order

This PR merges before the v0.81.0 release (#844). Conductor forks are created from a release, so the fix reaches them only through a release that contains it.

Checks

  • pytest tests/unit: 3400 passed
  • pre-commit, including actionlint and shellcheck: all hooks pass

Summary by Sourcery

Install a pinned, checksum-verified OpenTofu release with a repository script so lifecycle workflows resolve reliably on both GitHub Actions and Forgejo.

New Features:

  • Replace the Forgejo-incompatible OpenTofu setup action with a cross-platform installation script that pins OpenTofu 1.10.0 and verified architecture-specific checksums.

Bug Fixes:

  • Ensure lifecycle workflows can install OpenTofu on Forgejo runners where the setup-opentofu action is unavailable.

Enhancements:

  • Centralize OpenTofu installation and version management across workflows and the bootstrap composite action.
  • Validate runner compatibility, downloaded archive integrity, installed version, and PATH propagation before completing installation.

CI:

  • Run the OpenTofu checks when the installation script changes.
  • Add tests covering workflow usage, installation ordering, pinned checksums, and script refusal cases.

Documentation:

  • Document Forgejo action mirroring limitations and identify which repository actions are available or unavailable through the mirror.

Tests:

  • Add unit coverage for the pinned OpenTofu installer and workflow safeguards, including mutation-tested failure conditions.

    • Added coverage for installer validation, workflow usage, installation ordering, and checksum integrity.

A Conductor tenant fork could not deploy. Its first run on a Forgejo runner
stopped 22 seconds in, at `uses: opentofu/setup-opentofu@v2`:

    unable to clone 'https://data.forgejo.org/opentofu/setup-opentofu' …
    remote: Not found.

Forgejo resolves a bare `uses:` against DEFAULT_ACTIONS_URL, which the
forgejo stack pins to data.forgejo.org, and that mirror does not carry the
action. All six places that used it -- five workflows and nexus-bootstrap --
now run `.github/scripts/install-opentofu.sh`, a plain script that behaves
the same on GitHub Actions and on Forgejo.

The script:

- Installs the one pinned version, 1.10.0, and takes no arguments. Every
  workflow therefore gets the same OpenTofu, which tofu-checks.yaml relies
  on (a checker on a different version than the applier can pass what the
  applier rejects). nexus-bootstrap's `tofu_version` input is removed; no
  caller passed it.
- Verifies the archive against checksums pinned in the script. The issue
  proposed fetching SHA256SUMS at run time, but that file comes from the
  same place as the archive, so it would catch a broken download and not a
  replaced one. The pinned values come from tofu_1.10.0_SHA256SUMS after
  verifying it the way OpenTofu documents: `cosign verify-blob` with the
  identity `…/release.yml@refs/heads/v1.10` -> "Verified OK", and the same
  command with a wrong identity refused. Both pinned values were then
  compared with freshly downloaded archives: equal. The header says how to
  pin the next version.
- Uses the .tar.gz rather than the .zip, so it needs tar and not unzip.
- Reads the installed binary's version back before putting it on PATH, and
  appends to GITHUB_PATH, which both runners honour.
- Refuses non-Linux runners and architectures without a pinned checksum.

Measured on the deployed server: on Ubuntu 26.04 (amd64) and inside the
Forgejo runner's own image, node:22-bookworm, the script installs
`OpenTofu v1.10.0`, writes GITHUB_PATH, and a following step with that PATH
runs it. That image has curl, tar, gzip and sha256sum. arm64 was not run --
no such machine -- but its pinned checksum matches the real release archive.

Before switching, every affected job was checked to check the repository
out at its root before the install step, since the script lives in the
repository. tofu-checks.yaml now also triggers on changes to the script, so
the real install runs in CI whenever the script changes.

Tests (tests/unit/test_install_opentofu.py):

- no `uses:` of setup-opentofu, checked on parsed YAML so the explanatory
  comments do not count;
- the script is never called with a version;
- no job runs `tofu` before installing it, counting a local composite action
  that runs tofu (nexus-config-tfvars) as a tofu call, plus a guard that
  this rule still sees the lifecycle jobs;
- both checksums are pinned and well-formed;
- the script's refusals, run under bash with curl and uname replaced: a
  version argument, a non-Linux runner, an unpinned architecture, and an
  archive that does not match the pin, for both architectures -- nothing
  installed, nothing on PATH, and the reached URL asserted so the test is
  known to have got to the comparison.

Seven mutations, each caught: checksum comparison removed, argument check
removed, OS check removed, arm64 checksum removed, a workflow back on
setup-opentofu, a workflow passing a version, a workflow with no install.
The success path cannot be faked against a pinned checksum; CI runs it.

docs/stacks/forgejo-runner.md gets a section on what data.forgejo.org does
not mirror, checked on 2026-09-16 for every `uses:` in the repository --
tags with `git ls-remote`, pinned commit SHAs by fetching the commit, since
ls-remote cannot see them. After this change every `uses:` in the lifecycle
workflows resolves there; the four missing actions are CI-only
(actionlint, release-please, codecov, pytest-coverage-comment). The section
says that this covers action resolution only, not a full lifecycle run.

Closes #872.

Reviewer's Guide

The PR removes the unavailable opentofu/setup-opentofu dependency from all deployment paths and centralizes OpenTofu 1.10.0 installation in a portable Bash script with pinned checksums, platform/version validation, and GITHUB_PATH export. Workflow-level tests enforce consistent installation ordering and usage, while Forgejo mirror behavior and remaining full-run verification are documented.

Explanation

For #872, the PR replaces the six opentofu/setup-opentofu@v2 uses in .github/workflows/* and .github/actions/nexus-bootstrap/action.yml with .github/scripts/install-opentofu.sh. The script pins OpenTofu 1.10.0, checks amd64 and arm64 checksums, rejects unsupported runners, verifies the installed version, and writes GITHUB_PATH (.github/scripts/install-opentofu.sh:43-117). Unit tests cover action removal, installation ordering, checksum refusal, and runner refusal (tests/unit/test_install_opentofu.py). The Forgejo documentation lists missing mirrored actions (docs/stacks/forgejo-runner.md, “Actions that data.forgejo.org does not mirror”). However, the available evidence does not include the required successful Forgejo Conductor deployment or a complete lifecycle run. Static checks show the intended path, but they do not establish that the workflow reaches past Setup Control Plane on Forgejo.

Resolution

Provide reviewable evidence from a Forgejo Conductor fork deployment or an equivalent complete Forgejo lifecycle run. The evidence must show that the installer runs, reports OpenTofu v1.10.0, and allows the workflow to progress beyond Setup Control Plane.

A Conductor tenant fork got past checkout and the OpenTofu install
and failed at the next step on the Forgejo runner: `sudo: command
not found` (#884). The job image is node:22-bookworm. It runs as root
and has no sudo, jq, AWS CLI or pip. The lifecycle workflows were
written for GitHub's ubuntu-latest, which has all of them.

Chosen option: the workflows install what they need, as #874 did for
OpenTofu. The image stays small and unchanged.

- New .github/scripts/install-tool.sh <jq|cloudflared|awscli>. It
  installs a pinned version, checks it against a pinned checksum
  (amd64 and arm64), installs into $RUNNER_TEMP without root, reads
  the version back without a pipe (#883), and adds the directory to
  GITHUB_PATH.
  - jq 1.8.2: sha256sum.txt, GitHub's asset digest and the download
    agree.
  - cloudflared 2026.9.1: the release notes, GitHub's asset digest and
    the download agree.
  - AWS CLI 2.36.47, the official v2 installer: PGP signature verified
    against the key from the AWS install guide (fingerprint FB5D B77F
    ... 4672 475C), "Good signature" for both zips and "BAD signature"
    when the files are swapped. Installed with --install-dir and
    --bin-dir under $RUNNER_TEMP.
- cloudflared: the four `sudo mv` installs (setup-control-plane,
  spin-up, teardown, nexus-bootstrap) call the script instead. The
  version is pinned now, where it used to be `latest`.
- jq: installed right after checkout in setup-control-plane, spin-up,
  teardown, destroy-all and teardown-snapshot, before log-to-d1.sh
  first needs it.
- AWS CLI: installed in setup-control-plane (R2 credential validation,
  bucket cleanup) and in destroy-all (bucket deletion).
- PyYAML: generate-services-tfvars.py, sync-deployed-state.sh and
  sync-firewall-rules.sh import it with `python3`. After
  `uv sync --frozen --no-dev`, `.venv/bin` now goes first on
  GITHUB_PATH, and pyyaml is a runtime dependency. setup-control-plane
  had no uv and now sets it up.

Guard (tests/unit/test_job_toolchain.py): each lifecycle job may use,
beyond the image's baseline, only what an earlier step of the same job
installed. sudo and apt-get are never allowed. It follows local
composite actions and the scripts a step calls, and it counts
`ssh … nexus` and `nexus_deploy run-pipeline|s3-snapshot` as needing
cloudflared (the ProxyCommand). repo-secret.sh's gh is exempt: it is
used only on github.com. The rule has its own parametrised tests.
Reverting any install is caught, including cloudflared in
nexus-bootstrap, which a first version missed because nexus_deploy
uses it only through the SSH config.

CI (job-image-toolchain.yaml): on pull requests that touch the
installers, the actions, the runner config or the Python lock, a job
runs in node:22-bookworm. It installs everything, checks that each
tool answers from PATH, and renders the real services.yaml with
generate-services-tfvars.py. Tests keep its image equal to the
runner's label image and its installs a superset of the lifecycle
jobs'.

tests/unit/test_install_tool.py: pins well-formed and distinct per
architecture; refusals for a wrong argument, a non-Linux runner and an
unpinned architecture; a checksum mismatch for every tool and
architecture (URL asserted, nothing installed, PATH untouched); no
sudo and no early reader in the script. Four reverts, each caught.

Docs: forgejo-runner.md lists what the job image contains and what
installs the rest. CLAUDE.md has the rule under Development
Guidelines.

Not verified here: a whole lifecycle run on the Forgejo runner. That
needs a release and a Conductor fork dispatch.

Closes #884

Closes #884.

## What broke

A Conductor tenant fork now gets past checkout (#876) and the OpenTofu
install (#874). On the Forgejo runner it failed at the next step:

```text
sudo: command not found   (exit 127, in the cloudflared install)
```

The runner's job image is `node:22-bookworm`. It runs as root, and it
has none of `sudo`, `jq`, the AWS CLI or `pip`. The lifecycle workflows
were written for GitHub's `ubuntu-latest`, which ships all of them.

With `sudo` fixed, `jq`, the AWS CLI and PyYAML would each have been the
next failure.

## Approach (option B from #884)

The workflows install what they need, the way #874 does for OpenTofu.
The job image stays small and unchanged, and there is no third-party
runner image.

### `install-tool.sh`

New `.github/scripts/install-tool.sh <jq|cloudflared|awscli>`. For each
tool it:

- installs a pinned version and checks it against a pinned checksum, for
amd64 and arm64;
- installs into `$RUNNER_TEMP` without root;
- reads the version back without a pipe (#883);
- adds the directory to `GITHUB_PATH`.

| Tool | Version | How the checksum was verified |
|---|---|---|
| jq | 1.8.2 | the release's `sha256sum.txt`, GitHub's asset digest and
the download all agree |
| cloudflared | 2026.9.1 | the release notes, GitHub's asset digest and
the download all agree |
| AWS CLI v2 (official installer) | 2.36.47 | PGP signature checked
against the key in the AWS CLI install guide, fingerprint `FB5D B77F …
4672 475C`: "Good signature" for both zips, "BAD signature" when the
files are swapped |

### Workflow changes

| What | Where |
|---|---|
| `sudo mv cloudflared …` → `install-tool.sh cloudflared` (the version
is now pinned; it used to be `latest`) | `setup-control-plane`,
`spin-up`, `teardown`, `nexus-bootstrap` |
| `install-tool.sh jq`, right after checkout and before `log-to-d1.sh`
first needs it | `setup-control-plane`, `spin-up`, `teardown`,
`destroy-all`, `teardown-snapshot` |
| `install-tool.sh awscli` | `setup-control-plane` (R2 credential
validation, bucket cleanup), `destroy-all` (bucket deletion) |
| after `uv sync`, `.venv/bin` goes first on `GITHUB_PATH` | every job
that syncs, and `nexus-bootstrap` |
| `setup-uv` + `uv sync` added | `setup-control-plane`, which had no uv
|

**Why the `PATH` change.** `generate-services-tfvars.py`,
`sync-deployed-state.sh` and `sync-firewall-rules.sh` import PyYAML
under `python3`, and PyYAML is a runtime dependency of the project. With
`.venv/bin` first on `PATH`, `python3` resolves to the project
environment, which has it.

## Guards

### `tests/unit/test_job_toolchain.py`

A lifecycle job may use, beyond the image's baseline, only what an
earlier line of the same job installed. `sudo` and `apt-get` are never
allowed. The guard:

- follows local composite actions and the scripts a step calls;
- counts `ssh … nexus` and `nexus_deploy run-pipeline|s3-snapshot` as
needing cloudflared, because it is the SSH `ProxyCommand`;
- exempts `gh` in `repo-secret.sh`, which runs only on github.com.

The rule has its own parametrised tests, including the order of an
install and a use within one step.

**Reverts.** Removing any single install is caught. That includes
cloudflared in `nexus-bootstrap`, which a first version of the guard
missed.

### `.github/workflows/job-image-toolchain.yaml`

A new CI job that runs **in `node:22-bookworm`** on pull requests
touching the installers, the actions, the runner config or the Python
lock. It:

- installs everything;
- checks that each tool answers from `PATH`;
- renders the real `services.yaml` with `generate-services-tfvars.py`,
not just `import yaml`.

Tests keep its image equal to the runner's label image, and its installs
a superset of the lifecycle jobs'. This PR triggers it, so its first run
is part of this PR's checks.

### `tests/unit/test_install_tool.py`

- pins are well-formed and differ per architecture;
- refusals for a wrong argument, a non-Linux runner and an unpinned
architecture;
- a checksum mismatch for every tool and architecture: URL asserted,
nothing installed, `PATH` untouched;
- no `sudo` and no early reader in the script.

Four reverts, each caught.

`pytest tests/unit`: 3519 passed. Pre-commit (actionlint, shellcheck,
mypy): all hooks pass.

## Docs

- `docs/stacks/forgejo-runner.md`: what the job image contains, what
installs the rest, and what the two guards do and do not prove.
- `CLAUDE.md`: the rule, under Development Guidelines.

## Not verified yet

**A whole lifecycle run on the Forgejo runner.** Every fix so far moved
the failure one step further, so only a complete `initial-setup.yaml`
run on a Conductor fork settles #884. That needs a release with both
this PR and #885 (the exit-141 fix in the OpenTofu install).

**Release order:** merge #885 and this PR, then cut the release.

**Also not re-checked:** `install-opentofu.sh` on `main` still has the
`| head` from #883. The CI job above can therefore fail at random in its
OpenTofu step until #885 is merged.

## Local CodeRabbit round

Reviewed **`4b222edd`**: 3 findings, 2 themes.

- **Fixed in `9022423a` (minor):** the guard did not check the order of
an install and a use within one step. It now walks line by line.
- **Dismissed (major, twice):** pin `astral-sh/setup-uv` and
`actions/checkout` to commit SHAs. Every other workflow uses the same
tags, and pinning across the repository is #652.

`9022423a` itself was not reviewed locally; the PR review covers it.

## Summary by Sourcery

Make lifecycle workflows self-sufficient on minimal Forgejo runner
images by installing and validating all required tools without root
access.

New Features:
- Add a portable installer for pinned, checksum-verified jq,
cloudflared, and AWS CLI binaries on Linux runners.
- Add CI coverage that validates the complete lifecycle toolchain inside
the Forgejo runner image.

Bug Fixes:
- Make lifecycle workflows run on minimal Forgejo job images without
sudo, preinstalled jq, AWS CLI, or system PyYAML.
- Replace unpinned cloudflared downloads and root-dependent installation
with pinned, non-root installation.

Enhancements:
- Ensure project virtual-environment tools are used on PATH after
dependency synchronization.
- Add automated guards that detect missing or incorrectly ordered tool
installations, including forbidden sudo and apt-get usage.

CI:
- Expand Python test workflow triggers to cover workflow, action, and
script changes.

Documentation:
- Document the Forgejo runner image contents, lifecycle tool
installation requirements, and CI safeguards.

Tests:
- Add unit tests for installer validation, checksum failures, supported
platforms, and lifecycle toolchain ordering.
