Why

assign-ids.yml pushes its auto-commit with the default GITHUB_TOKEN. That push is not treated as a normal contributor push: it either triggers no workflow runs at all (GitHub's recursion guard) or creates runs stuck in action_required. Both behaviours were observed on the same afternoon, 2026-08-14, across PRs #582-#587.

Either way validate and audit — required contexts on main (ruleset 11289515) — never report on the commit assign-ids just pushed.

The failure mode is quiet, which is the real problem. A run in action_required does not appear in gh pr checks output at all, so the PR does not go red. It shows fewer checks than it should, every check it does show is green, and it is unmergeable with nothing obviously wrong. Four of the six catalog import PRs were sitting in exactly that state until the runs were approved by hand.

What this does

Mints a GitHub App token and hands it to actions/checkout, so the resulting synchronize event looks like any other contributor push and the required checks run normally.

The token step is gated on vars.ASSIGN_IDS_APP_ID != '' and the checkout falls back to secrets.GITHUB_TOKEN, so this is a no-op until the App is configured — it can merge now and degrades to today's behaviour rather than failing outright.

Follow-up needed to activate

Setup steps are in the new .github/README.md. Short version: create an org GitHub App with Contents: read and write, install it on this repo, then set the ASSIGN_IDS_APP_ID variable and ASSIGN_IDS_APP_PRIVATE_KEY secret.

ASSIGN_IDS_APP_ID is a variable rather than a secret on purpose: secrets are not readable in if: conditions, so the graceful fallback needs it in vars.

Notes

  • No changeset: the changeset gate only fires on data/**/*.yaml changes.
  • url-health.yml also pushes with GITHUB_TOKEN, but it commits a cache file to the default branch rather than a PR branch, so no required check depends on it. Left alone deliberately.

Summary by CodeRabbit

  • New Features

    • Automated commits can now use a configured GitHub App identity, with a fallback to the standard repository token.
  • Documentation

    • Added setup guidance for GitHub App permissions, repository settings, fallback behavior, and workflow verification.

Refs AUREO-936 (the App creation step this PR depends on).

A GITHUB_TOKEN push either triggers no workflow
runs or leaves them in action_required, so the
required validate and audit checks never report
on the commit assign-ids pushes and the PR is
unmergeable while still looking green.

Falls back to GITHUB_TOKEN until the app is
configured.

Review Change Stack

Walkthrough

The assign-ids workflow optionally uses a GitHub App token for checkout and commit pushes. .github/README.md documents setup, fallback behavior, required permissions, repository settings, and verification commands.

Changes

assign-ids authentication

Layer / File(s) Summary
App-token checkout and verification
.github/workflows/assign-ids.yml, .github/README.md
The workflow mints a token from ASSIGN_IDS_APP_ID and ASSIGN_IDS_APP_PRIVATE_KEY when configured. It falls back to GITHUB_TOKEN and passes the selected token to checkout and commit pushes. The README documents setup and verification commands.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟠 High · up to 25c85

This PR introduces a write-capable app identity for automated pushes, but the workflow can currently fail under partial configuration, grant broader permissions than needed, and expose persisted credentials to pull-request-controlled commands. These create concrete availability and security risks, so the PR is not merge-ready until the token gating, permission scope, and credential persistence are fixed.

State that verification requires a same-repository PR.

.github/workflows/assign-ids.yml Line 18 skips the job when github.event.pull_request.head.repo.fork == true. A PR from a fork therefore produces no auto-commit or App-token verification run. Update these instructions to require a branch in existential-engineering/catalog, or document the expected skip.

GitHub CLI gh run list --json workflowName status event --status documentation

💡 Result:

The GitHub CLI command gh run list --json workflowName,status,event --status <status> is a valid way to list workflow runs with specific JSON fields filtered by a particular status [1][2][3]. Breakdown of the command components: --json workflowName,status,event: This flag restricts the output to only include the specified fields in JSON format [1][3]. The available fields for this command include attempt, conclusion, createdAt, databaseId, displayTitle, event, headBranch, headSha, name, number, startedAt, status, updatedAt, url, workflowDatabaseId, and workflowName [2][3]. --status : This flag filters the list of runs based on their current status [1][3]. You must replace with one of the following valid values: queued, completed, in_progress, requested, waiting, pending, action_required, cancelled, failure, neutral, skipped, stale, startup_failure, success, or timed_out [1][3]. Example usage: To list only successful workflow runs and output their name, status, and triggering event in JSON: gh run list --json workflowName,status,event --status success

Citations:


Make the diagnosis conditional.

Missing validate=pass or audit=pass does not prove App authentication failed or that a run awaits approval. Fork pull requests skip assign-ids, and queued, waiting, or pending runs do not match the current conclusion=="action_required" filter. Include status, event, and workflowName in --json, and inspect the assign-ids run before diagnosing App setup.

GitHub Actions create-github-app-token v3.2.0 action.yml private-key required input behavior empty private key

💡 Result:

In the actions/create-github-app-token GitHub Action, the private-key input is explicitly marked as required in the action.yml configuration file [1]. As of version 3.2.0, the action includes specific validation logic to handle cases where the private-key input resolves to an empty value [2][3]. Previously, an empty input would pass through to the underlying Octokit library, resulting in a generic error message regarding the privateKey option [3]. In version 3.2.0, the action performs an early check to ensure the input is a non-empty string, and if it is empty, the action will now fail with a clear, action-specific error message designed to guide users correctly [3]. This change ensures that users receive immediate feedback that the private key is missing or invalid, rather than encountering an implementation-detail error from the authentication library [3].

Gate token minting on both App values.

When ASSIGN_IDS_APP_ID is set without ASSIGN_IDS_APP_PRIVATE_KEY, actions/create-github-app-token@v3.2.0 rejects the empty private-key, so the workflow fails before the GITHUB_TOKEN fallback. Add a step-scoped preflight check for both values and gate Mint app token on its boolean output. Keep the private key out of job-level environment variables.

actions/create-github-app-token v3.2.0 permission-contents default permissions inherited installation documentation

💡 Result:

In the actions/create-github-app-token action (including version 3.2.0), the permission-contents input is an optional configuration parameter used to explicitly set the access level for repository contents (such as commits, branches, and releases) [1][2]. Key technical details regarding this input and the action's permission inheritance include: 1. Default Behavior: By default, if no permission-*-type inputs are provided, the generated GitHub App installation access token inherits all the permissions currently granted to the GitHub App's installation [3][4]. 2. Purpose of Explicit Permissions: When you provide an explicit permission input like permission-contents (which accepts values of 'read' or 'write'), you are overriding the default behavior [1][2]. This allows you to restrict the token's scope following the principle of least privilege [5]. 3. Important Considerations: - Selecting permissions that are not granted to the app's installation will result in an error [4]. - If you encounter authorization errors (e.g., 422 or 403) after setting specific permission- inputs, it is often because the configured permissions are insufficient for the operations you are performing [6]. Removing these specific inputs allows the token to revert to the full set of inherited installation permissions, which can help diagnose whether the issue is caused by overly restrictive settings [4][6]. The documentation recommends explicitly listing only the required permissions for your use case to ensure better security [4]. This aligns with GitHub's broader best practices for controlling workflow token permissions [4].

Constrain the App token permissions explicitly.

Set permission-contents: write. Without an explicit permission-* input, actions/create-github-app-token@v3.2.0 grants the token all permissions assigned to the App installation. Explicit permissions prevent future App permission changes from expanding this credential.

actions/checkout persist-credentials default .git/config token actions/create-github-app-token pull request security

💡 Result:

The actions/checkout action uses persist-credentials: true as its default behavior [1][2][3][4]. When enabled, this setting configures the provided authentication token (or SSH key) into the local Git configuration of the checked-out repository, allowing subsequent Git commands in the workflow to run authenticated [5][3][4]. Recent updates to actions/checkout have improved the security of this process by moving credential storage out of the repository's main .git/config file and into a separate, temporary configuration file under $RUNNER_TEMP [5][3][6]. This new method utilizes Git's includeIf mechanism to conditionally include these credentials only when needed, reducing the risk of accidental credential exposure [6]. The token is still automatically removed during post-job cleanup [5][3]. When using actions/create-github-app-token to generate a GitHub App installation token for tasks like pushing to a pull request, it is common practice to pass this token to the actions/checkout step [7][8][9]. To ensure the workflow uses the App token rather than the default GITHUB_TOKEN, and to prevent the repository's configuration from potentially persisting unintended credentials, developers often explicitly set persist-credentials: false in the actions/checkout step [7][8][9]. Security considerations regarding persist-credentials primarily stem from the potential for credentials to be accessed by malicious steps within a workflow [10]. While the recent move to a separate temporary file mitigates certain risks—such as accidental leakage through artifact publishing—using persist-credentials: false remains a recommended security hardening practice when you need to control precisely which credentials are used for Git operations or when you want to minimize the credential footprint within the runner environment [7][8][9].

Disable checkout credential persistence before running PR code.

actions/checkout persists the token by default. This workflow runs PR-controlled pnpm commands before git push, so same-repository PR code can access the persisted Git credentials and use the contents: write token. Set persist-credentials: false, then set GH_TOKEN and run gh auth setup-git only in the final commit step before git push.

credentials from being available during PR-controlled commands. In the final
commit-and-push step, set GH_TOKEN and run gh auth setup-git immediately before
git push, preserving authentication only for that push.

* ci: harden assign-ids app-token flow

Follow-ups to #622 that were left uncommitted when it merged:

- Gate the token mint on the private-key secret too: with only the
  ASSIGN_IDS_APP_ID var set, create-github-app-token hard-fails, which
  defeated the intended graceful fallback to GITHUB_TOKEN. Secrets are
  not readable in `if:`, so a step exposes a boolean instead.
- Scope the App token to permission-contents: write.
- persist-credentials: false on checkout so PR-controlled `pnpm install`
  lifecycle scripts can't read the token; the push step re-authenticates
  via `gh auth setup-git`.
- Expand the README verification docs: fork-PR gate caveat and a
  step-by-step diagnostic order for reading run results.

* ci: address review feedback on assign-ids hardening

- Split the bot commit from the push: git commit now runs with no token
  in its environment, and both commit and push disable repo-controlled
  hooks (husky's hooksPath is installed by `pnpm install`'s prepare
  script) via core.hooksPath=/dev/null. Only the push step sees the
  token.
- README diagnostics: distinguish a path-filter miss (no run created)
  from a fork PR (run exists, job skipped); note a no-op run also covers
  already-assigned hardware io keys, not just ids; approval-gated runs
  show conclusion=action_required (status stays completed — verified
  against live run data), and list waiting/pending among incomplete
  statuses.
