Queued CI/CD Adoption

Brings operations, common-module, and infrastructure onto the Queued CI/CD model already running in documentation and arda-frontend-app: a GitHub merge queue with ALLGREEN grouping, changelog entries authored in the PR body, and post-merge assembly into CHANGELOG.md.

The three target repositories differ from the two live ones on one structural point that shapes the whole project: CHANGELOG.md is their build-time version source. The adaptation inverts the order — assemble the release block first, then build and publish from the assembly commit.

Documents

goal.md — purpose, scope, repositories, success criteria.
requirements.md — the numbered requirements the design implements, each traced to its source, with the open ones called out.
design.md — the adapted pipeline: structure, behavior, verification, operations impact.
decision-log.md — the decisions that shaped the design, with rejected alternatives.

What the rollout changed about the design

The design survived first contact only in outline. Rounds 4 to 6 of the decision log were driven by production behaviour rather than design review, and three of their findings changed shared components rather than this project’s own code:

No component owned exactly one decision (DQ-008). Entry resolution was implemented three times across two repositories, and the copies disagreed. It is now one component, synthesize-changelog-entry.
An empty input could not mean “none” (DQ-010), so every ordinary build fell back to a derivation that rejects exactly what a merge queue stages.
The component’s contract omitted its hardest caller (DQ-011), which assembly worked around by reaching into its implementation.

Each was found by running the pipeline, not by reading it. Two had passed review.

Prior art

Queued CI/CD — the canonical specification of the target model.
Phase 2 — Queued PRs and Tiered Gates — the arda-frontend-app rollout, completed 2026-04-28.
Frontend PR Process — the contributor how-to that will need a backend counterpart.
