Purpose / companion changes

Replace privileged, locally inherited Linux test runners with a reproducible non-root image, and test Platform requirements changes before merge. Target: v4.2-dev, milestone v4.2.0.

Changes

  • Linux Rust/Kotlin test jobs verify prebaked native dependencies and the exact image contract instead of installing host packages or changing host device permissions.
  • Platform owns .github/runner-requirements.json: locked inputs and immutable recipe revision baf8849b900555d66714e0e1fcffdff669b9e404.
  • Manifest edits force candidate selection for Rust/Kotlin. Jobs bind the full PR head and candidate digest; ordinary PRs keep the ordinary pool. Existing fork guards remain unchanged.
  • Hosted Linux retains its provisioning path; native macOS remains separately provisioned.
  • Kotlin tests use the pinned emulator with writable per-job AVDs, KVM access checks, and the existing screen-on/PIN/unlock behavior.
  • Shared image verification, selector tests, and operator documentation accompany the workflow changes.

4.2 reconciliation

Rebuilt directly on v4.2-dev at a5a1af5e0557d81eee02c3b2cf73b34b23ad4972, preserving only the intended CI delta: 12 CI/documentation files, no application-code or PR Hygiene changes.

  • .github/workflows/release-kotlin-sdk.yml is byte-identical to 4.2. Its fresh forced cargo-ndk install, checksum-verified protoc, persistent build cache, and isolated hosted publication are preserved.
  • Rust coverage-tool verification retains if: ${{ inputs.coverage }}. Other pinned helpers fail early when missing or the wrong version; jobs do not silently install replacements.
  • Preserved 25 unaffected Rust test steps, including current wallet-closure, transport-free, and test-phase logic, plus existing trusted-fork guards.
  • Documentation now reflects 4.2's self-hosted Kotlin release build and separate hosted publication.

Validation of the rebuilt head

  • 7 runner-selection/input-validation tests passed.
  • 6 local tool-version cases passed: correct, wrong and missing versions for llvm-cov and nextest.
  • actionlint passed for every changed workflow; 85 embedded Bash scripts passed syntax checks.
  • Strict requirements-manifest validation passed using the exact pinned image recipe's validator. Python compilation, standalone Kotlin shell syntax, and git diff --check passed.
  • Preservation checks confirmed unchanged Kotlin release and PR Hygiene workflows, retained coverage condition and fork guards, and no application changes.
  • New-head GitHub CI is reported by the checks below. These local gates do not prove real Rust/Kotlin jobs on the candidate image.

The previously published baseline dashpay/dash-selfhosted-image@sha256:c6be26ecd711c7f4aa0a6a152640c6fee3454be1de645c810ef26aa32c13e919 predates the exact manifest/recipe contract and is not this PR's candidate.

Runtime and rollout boundary

The candidate runtime is non-root UID/GID 1001:1001, with no sudo/Docker CLI/socket, all capabilities dropped, no-new-privileges, and default seccomp/AppArmor. Only Kotlin receives KVM access. GitHub App and Docker authority remain in the host controller; registry credentials remain in the separate publisher.

Before merging this consumer:

  1. Land ci: bootstrap PR-first runner image publishing #4912 on v4.2-dev and complete the reviewed App/group/controller setup.
  2. Arrange explicit test authorization for this fork without broadening persistent-runner access.
  3. Prove actual Rust and Kotlin jobs on this exact head/candidate digest; skipped jobs cannot satisfy promotion.
  4. Drain/switch ordinary runner capacity to the matching reviewed image, keeping rollback. Old/native Linux pools will fail the exact contract checks.

Promotion changes registry channels, not running containers. This reconciliation does not merge either PR, deploy a controller, or modify live runners. See .github/SELF_HOSTED_RUNNER.md for the operator procedure.

In-place changes to shipped generations

None: CI configuration, helpers, tests and documentation only; application APIs are unchanged.

Checklist

  • CI-only replay onto v4.2-dev, milestone v4.2.0
  • Conflicts resolved while preserving newer 4.2 hardening
  • Focused local validation and self-review completed
  • Real candidate Rust/Kotlin jobs and ordinary-pool rollout proved

📝 Walkthrough

Walkthrough

The PR documents the self-hosted runner contract and updates Kotlin and Rust CI workflows to verify pre-installed dependencies instead of using host package installation.

Changes

Self-hosted runner dependency contract

Layer / File(s) Summary
Runner contract
.github/SELF_HOSTED_RUNNER.md
Defines container security settings, KVM access, required toolchains, and Docker publishing restrictions for self-hosted runners.
Workflow dependency verification
.github/workflows/kotlin-sdk-build.yml, .github/workflows/tests-rs-workspace.yml
Replaces package and tool installation with checks for required dependencies. The Kotlin workflow also verifies protoc version 32.0 and documents KVM group access.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~15 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 65ba4

CI can obtain different Cargo tool versions at runtime instead of using the declared runner image. Provision and verify these tools in the image, or explicitly document and pin the allowed user-local installs before merging.

Final validation — Phase 2 only (queue backlog)

Verified the shared Rust action regression at head 961e45e: its self-hosted image checks also run in GitHub-hosted Ubuntu workflows that previously received dependency installation. Retained this as a suggestion under the supplied severity policy for non-consensus correctness issues; the affected callers and failure path are confirmed, but hosted-image package inventories and workflow execution were not independently tested.

In `.github/actions/rust/action.yaml`:
- [SUGGESTION] .github/actions/rust/action.yaml:134-135: Do not require self-hosted Debian packages in the shared action on hosted runners
  This step is gated only by `runner.os == 'Linux'`, but the action is also called by `ubuntu-24.04` jobs in `release.yml`, `tests-rs-nightly-long-running.yml`, `tests-build-js.yml`, and `book.yml`. Those callers do not provision these packages before invoking it. Replacing the previous apt installation with unconditional package checks makes those hosted jobs fail during setup whenever `clang`, `llvm`, or `libsnappy-dev` is absent, even though rebuilding the project's pinned self-hosted image cannot change their environment. Apply the image-only verification to self-hosted runners and preserve dependency provisioning for GitHub-hosted runners, for example by branching on `runner.environment`. This keeps the persistent runners non-root without imposing their image contract on ephemeral consumers.

Re-review — Final validation — Phase 2 only (queue backlog)

Independently reviewed the complete PR diff at fb3d76c and found no actionable in-scope defects; the prior hosted-runner dependency regression is fixed. All seven selector tests, manifest environment export, changed workflow YAML parsing, Bash syntax checks for 97 embedded scripts and the instrumented-test script, and diff whitespace checks passed locally. Approval covers this exact source head, not operational activation: companion infrastructure, real Rust/Kotlin execution on the exact candidate image, and ordinary-runner rollout remain unverified here and subject to the documented merge gates.

* feat: an account that opens pull requests without a person behind it is not asked to attest

`ktechmidas` posted `/self-reviewed` on dashpay/platform#4702 and it
counted for nothing: the pull request was opened by `infraclaw-dash`, and
an attestation is the author's own. That is right — a colleague cannot
attest for you — but `infraclaw-dash` is one of the accounts this
organisation runs its automation from, and there is nobody behind it to
post one. Its three open pull requests would wait for ever.

GitHub marks Copilot and dependabot as bots and those were already
handled. These accounts are ordinary users by every API, so the policy
names them: `bot_authors`, beside `required_bots`. A pull request from
one is asked for no attestation, and is told nothing about its move —
there is nobody there to take it. What it is owed is unchanged: it owns
no area, so it still needs an eligible human approval, and that approval
is what stands in.

The policy is refused if it names a machine author as an owner or a
reviewer anywhere. With both the owner exemption and the stand-in, such a
pull request would need neither an attestation nor an approval, and could
merge with nobody having read it at all.

Named: infraclaw-dash, DCG-Claude and Claudius-Maginificent on platform;
Claudius-Maginificent on dash-evo-tool, where it has six open pull
requests. Dry run on platform: five pull requests change verdict, all
five theirs, two of them straight to ready-to-merge on approvals they
already hold.

Mutation-checked: four behaviours reverted in turn, each caught by a test
naming it; 315 tests.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* fix: read the handles after they are known to be handles

Reaching into an area's owners for the machine-author cross-check ran
before `_handles` had seen them, so a policy with a non-string there —
a null from a bad merge, a nested list from a paste — raised
AttributeError, which `evaluate` does not catch. What used to be a
reported configuration error became a crash that left every pull request
in the repository without a status for that run, and the cross-repository
digest with it.

The check moves to the end of validation, where every handle has been
read. Also pinned: that the refusal is case-insensitive, which is the
property that keeps the owner exemption closed; that a machine author
cannot approve its own pull request, nor a sibling machine author's; that
fallback reviewers are covered too; and that a well-formed handle in
`bot_authors` validates — without that last assertion the test passed
against an engine that rejected the field outright.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* fix: the engine learns the field before any policy carries it

A caller runs the engine at its own pin and reads the policy live from
this repository's default branch. A policy naming `bot_authors` while a
caller is still pinned to an engine that does not know the key is an
unknown field to it, which is a configuration error on every pull request
in that repository — a red required check, and nothing merges anywhere
until each caller has been re-pinned by a pull request that itself needs
a green check. The repository's own CI gate says so, and was red on this
branch for exactly that reason.

So the policies come out of this one. The order is: this engine merges,
all five callers re-pin, then `bot_authors` lands in platform.json and
dash-evo-tool.json.

…nd them (#52)

`infraclaw-dash`, `DCG-Claude` and `Claudius-Maginificent` open pull
requests in this organisation and nobody is behind them to post
`/self-reviewed` — on dashpay/platform#4702 a colleague posted one and it
counted for nothing, because an attestation is the author's own. All
seven callers are pinned to an engine that knows `bot_authors`.

Claudius-Maginificent is named on dash-evo-tool as well, where it has six
open pull requests waiting on an attestation for the same reason.

Each still needs the eligible human approval it cannot do without; that
approval is what stands in for the attestation. Dry run on platform: five
pull requests change verdict, all five theirs, two straight to
ready-to-merge on approvals they already hold.
