kevinveenbirkenbachandClaude Opus 4.7 50bc41b449 chore(ci): route CodeQL through orchestrator only, dedupe CI docs

Remove the direct push-on-main trigger from security-codeql.yml so that
the concurrency group no longer cancels the orchestrator-invoked scan.
CodeQL now runs exactly once per CI run via ci-orchestrator.yml, and
its failure continues to block code-quality-gate and all downstream
deploy, install, and environment tests.

Split the CI documentation along SPOT lines: workflows.md owns the
per-workflow catalog (trigger, inputs, short description); pipeline.md
owns the flow (stages, gates, concurrency, fork handling). Drop the
duplicated entry-points table and per-stage workflow bullet lists from
pipeline.md in favour of cross-references. Fix the stale "push to
latest" wording that pre-dated the current branch prefix list.

Continuous Integration 🔄

This document describes the CI pipeline structure, entry points, and gates used in Infinito.Nexus. For the catalog of every workflow file (description, triggers, inputs) see workflows.md.

Overview 🗺️

CI is triggered automatically on pull-request events and on pushes to the branches listed in the entry-workflow row in workflows.md. The pipeline is composed of reusable workflow files under .github/workflows/. The central coordinator is ci-orchestrator.yml, which is called by the entry workflows.

Entry Points 🚪

Every external CI trigger MUST route through one of the entry workflows. Each entry translates its event into a call to the orchestrator; the catalog of triggers and inputs lives in workflows.md.

entry-pull-request-change.yml: detects PR scope and conditionally calls the orchestrator.
entry-push-latest.yml: calls the orchestrator for pushes on the supported branch prefixes and additionally invokes the release workflow on version tags.
entry-manual.yml: dispatches the orchestrator manually for a chosen distro set and whitelist.

PR Scope Detection 🔎

Before the full pipeline runs, CI detects the scope of the PR based on the changed files and the branch prefix (see branch.md).

Documentation-only and agent-only PRs MUST pass a lightweight gate without running the full orchestrator.
All other scopes MUST run the full ci-orchestrator.yml.
The branch prefix MUST match the detected scope, otherwise the validate-pr-branch-prefix job fails.

Pipeline Stages 🏗️

The orchestrator runs the following stages in order:

1. Fork Prerequisites ⏳

For fork PRs, CI waits for privileged images to be built by the pull_request_target event before proceeding. This ensures untrusted code never runs with elevated permissions.

2. Security 🛡️

The security-codeql job runs the CodeQL scan (catalogued in the Security and linting table of workflows.md). A failing scan MUST fail code-quality-gate and thereby block all downstream deploy, install, and environment tests.

3. Linting 🧹

All linting workflows listed in the Security and linting table of workflows.md run in parallel. All of them MUST pass lint-gate before the pipeline continues.

4. CI Image Build 🐳

The build-ci-images stage uses images-build-ci.yml to build Docker images for the target distributions (arch, debian, ubuntu, fedora, centos). These images are consumed by all subsequent test jobs.

5. Code Tests 🧪

All code-test workflows listed in the Code tests table of workflows.md run in parallel once the CI images are available. All of them MUST pass test-code-gate.

6. Code Quality Gate 🚦

The code-quality-gate requires linting, code tests, and security checks to all pass before deploy tests are triggered.

7. DNS Tests 🌐

test-dns.yml validates DNS configuration across all target distributions.

8. Image Mirroring 🪞

images-mirror-missing.yml mirrors any missing upstream images in parallel with the DNS tests so later deploy jobs pull from GHCR instead of Docker Hub, MCR, or other external registries. This shields CI from upstream rate limits, geo-blocking, and transient registry outages.

Fork PRs cannot publish mirror packages directly, so their untrusted runs wait for the trusted mirror producer before continuing. See mirror.md for the mirroring architecture and naming convention.

GHCR publication uses the workflow GITHUB_TOKEN; optional Docker Hub secrets are used only to reduce source-side Docker Hub rate limits while mirroring. See authentication.md.

9. Deploy Tests 🚀

The three deploy-test workflows listed in the Infrastructure tests table of workflows.md (server, universal, workstation scopes) run in parallel once DNS and mirroring have completed.

10. Installation Tests 📦

The install-test workflows listed in the Infrastructure tests table of workflows.md run in parallel once code-quality-gate is green. All of them MUST pass test-install-gate.

11. Development Environment 🛠️

The test-development stage runs the development-environment workflow listed in the Infrastructure tests table of workflows.md.

12. Done 🏁

The final done job aggregates all deploy, install, and development gates. CI is considered green only when this job succeeds.

Concurrency 🔀

PR pipelines use cancel-in-progress: true so only the newest run per PR and event type is active.
The orchestrator uses cancel-in-progress: false to avoid interrupting long-running deploy tests mid-flight.
The push entry workflow (entry-push-latest.yml) defaults to cancel-in-progress: true but respects the repository variable CI_CANCEL_IN_PROGRESS.

See configuration.md for all repository variables that control CI behaviour.

Fork PRs 🍴

Fork PRs run under the pull_request event without write permissions. Privileged steps (image builds, package writes) run via pull_request_target after a maintainer review. The fork CI waits for those privileged images before proceeding. See pull-request.md for the contributor-facing fork workflow.
