CI Configuration ⚙️

This page lists every repository variable that controls GitHub Actions CI behaviour in this repo. For the workflow catalog see workflows.md; for the CI flow see pipeline.md.

Repository variables are set under Settings → Secrets and variables → Actions → Variables.

Variables 📋

Variable	Workflow	Default (unset)	Set to activate
CI_CANCEL_IN_PROGRESS	entry-push-latest.yml	Cancels in-progress runs on new push	false to keep in-progress runs alive
CI_RUN_ON_MAIN	entry-push-latest.yml	Pushes to main skip CI	true to run CI on main pushes too
CI_ENABLE_AUTO_UPDATES	update.yml, dependabot-close.yml	Update jobs skipped; Dependabot PRs auto-closed	true to allow update PRs (workflow-driven and Dependabot)
INFINITO_PLAYWRIGHT_KEEP	test-deploy-server.yml, test-deploy-universal.yml, test-deploy-workstation.yml, test-deploy-local.yml	Playwright keeps trace, screenshot and video only when a test fails	true to keep them for every test (passing runs included)

CI_CANCEL_IN_PROGRESS 🛑

Controls whether a new push cancels an already-running CI pipeline on the same branch.

Default behaviour (variable not set or set to any value other than false): In-progress runs are cancelled when a new push arrives. This is the recommended setting for most workflows.

To disable cancellation:

1. Open the repository on GitHub.
2. Go to Settings → Secrets and variables → Actions.
3. Switch to the Variables tab.
4. Click New repository variable.
5. Set Name to CI_CANCEL_IN_PROGRESS and Value to false.
6. Save.

To re-enable cancellation:

Delete the variable or change its value to anything other than false (e.g. true).

How it works:

cancel-in-progress: ${{ vars.CI_CANCEL_IN_PROGRESS != 'false' }}

Variable value	Expression result	Behaviour
(not set / empty)	'' != 'false' → true	Cancels in-progress runs ✓
false	'false' != 'false' → false	Does not cancel ✓
true	'true' != 'false' → true	Cancels in-progress runs ✓

CI_RUN_ON_MAIN 🎯

Controls whether pushes to main trigger the CI pipeline. Pushes to all other branches covered by the workflow (feature/**, hotfix/**, fix/**, alert-autofix-*) are unaffected.

Default behaviour (variable not set or set to any value other than true): Pushes to main are gated out at the run-policy job and CI is skipped.

To enable CI on main pushes:

1. Open the repository on GitHub.
2. Go to Settings → Secrets and variables → Actions.
3. Switch to the Variables tab.
4. Click New repository variable.
5. Set Name to CI_RUN_ON_MAIN and Value to true.
6. Save.

To disable again:

Delete the variable or change its value to anything other than true.

How it works:

The gate is applied inside push_ci_policy.sh, which the run-policy job invokes. When GITHUB_REF == refs/heads/main and CI_RUN_ON_MAIN != 'true', the job emits should_run=false and every downstream job is skipped.

Variable value	Ref is main	Behaviour
(not set / empty)	yes	CI skipped ✓
true	yes	CI runs ✓
any other value	yes	CI skipped ✓
(any)	no	Unaffected (CI runs per branch rules) ✓

CI_ENABLE_AUTO_UPDATES 🔄

Controls whether automated update PRs are created. Covers both the workflow-driven jobs in update.yml (Docker image versions, agent skills) and PRs opened by Dependabot (gated via dependabot-close.yml, which auto-closes them).

The workflow-driven jobs additionally require the BOT_APP_CLIENT_ID and BOT_APP_PRIVATE_KEY repository secrets, see secrets.md. Without those secrets, runs fail at the token-minting step and no PR is opened.

Default behaviour (variable not set or set to any value other than true): The update-docker-image-versions and update-skills jobs are skipped. Dependabot PRs are auto-closed on open with a comment pointing to this variable.

To enable update PRs:

1. Open the repository on GitHub.
2. Go to Settings → Secrets and variables → Actions.
3. Switch to the Variables tab.
4. Click New repository variable.
5. Set Name to CI_ENABLE_AUTO_UPDATES and Value to true.
6. Save.

To disable again:

Delete the variable or change its value to anything other than true.

How it works:

In update.yml each job carries a job-level guard:

if: vars.CI_ENABLE_AUTO_UPDATES == 'true'

Dependabot cannot read repository variables itself, so dependabot-close.yml listens on pull_request_target (opened, reopened) and closes any PR authored by dependabot[bot] while CI_ENABLE_AUTO_UPDATES != 'true'. The workflow does not check out PR code, which keeps the elevated pull_request_target context safe.

Variable value	Workflow update jobs	Dependabot PRs
(not set / empty)	Skipped ✓	Auto-closed on open ✓
true	Run ✓	Stay open ✓
any other value	Skipped ✓	Auto-closed on open ✓

INFINITO_PLAYWRIGHT_KEEP 🎬

Controls whether Playwright keeps trace, screenshot, and video for every test or only for failing tests across the four deploy-test workflows (test-deploy-server.yml, test-deploy-universal.yml, test-deploy-workstation.yml, test-deploy-local.yml). For the full propagation chain, the inventory override, and the local equivalents, see Playwright Tests.

Default behaviour (variable not set or set to any value other than true): Artefacts are retained only when a test fails.

To retain artefacts for every test:

1. Open the repository on GitHub.
2. Go to Settings → Secrets and variables → Actions.
3. Switch to the Variables tab.
4. Click New repository variable.
5. Set Name to INFINITO_PLAYWRIGHT_KEEP and Value to true.
6. Save.

To disable again:

Delete the variable or change its value to anything other than true.

How it works:

Each deploy-test workflow forwards the variable into its own env: block:

INFINITO_PLAYWRIGHT_KEEP: ${{ vars.INFINITO_PLAYWRIGHT_KEEP }}

Variable value	Behaviour
(not set / empty)	Trace / screenshot / video kept only on failure ✓
true	Trace / screenshot / video kept for every test ✓
any other value	Trace / screenshot / video kept only on failure ✓
