Summary

Last night's canary failed on both Ubuntu legs before any test ran, in ruby/setup-ruby:

Error: Unavailable version 3.4.8 for ruby on ubuntu-26.04
  Only the latest patch release of each series is built for newer runner images.

ubuntu-latest started moving to Ubuntu 26.04 on October 19 (actions/runner-images#14748). setup-ruby only builds the newest patch of each series there. Every setup-ruby step that gave no ruby-version read .ruby-version, which pinned 3.4.8.

• CI asks for the series. Every ruby/setup-ruby step in canary.yml, main.yml and release.yml now asks for ruby-version: '3.4'. In main.yml's package-manager matrix, the default legs now map to '3.4'; the '4.0' legs are unchanged, and the if: matrix.ruby == 'default' conditions still match. release.yml's verify jobs already asked for '3.4', but six jobs (platforms, build-darwin, build-linux, build-windows, build-plain, publish) did not.
• release.yml matters on Windows too. setup-ruby's Windows builds stop at 3.4.11, so an exact 3.4.12 cannot install there. With only the .ruby-version bump, build-windows would have failed on the next release.
• .ruby-version is 3.4.12, and AGENTS.md says so too.
• Gemfile.lock gains the arm64-darwin-27 platform, which Bundler added on a macOS 27 host.

Test Coverage

Application code paths: 0. The changes are CI workflow config, .ruby-version, one lockfile platform and one doc line. No test reads any of them, so the CI runs are their test.
Coverage gate: could not determine percentage (no application code paths), so it was skipped.
Tests ran: test-all count unavailable (runner summary not recognised; the suites printed 812 Ruby runs, Go ok, 9 Bun tests)

Pre-Landing Review

One finding, fixed with approval: release.yml's six setup-ruby steps read .ruby-version (build-windows cannot install 3.4.12 from setup-ruby's Windows table). A second pass found nothing.

Gate edits: none detected (12 listed, 1 read; patterns: RH-1,RH-3,RH-4,RH-12,RH-13,RH-14,RH-15,RH-16; unlisted idioms: none)

Adversarial review: the Claude pass completed and found no defect in the diff. It noted the bundled-with gap below for the PR run to settle.

Outside review (Codex): missing coverage. Its verdict was unverified: it reported no findings but without severity tags.

Exploratory QA

Functional surface: CI jobs, smoke budget, 4 probes. Every probe was a read of GitHub state.

• Pass: canary run 39931392704 on 716f25c succeeded on 6/6 jobs.
• Pass: on Ubuntu 26.04, setup-ruby resolved '3.4' to 3.4.12.
• Pass: on macOS 26, setup-ruby resolved '3.4' to 3.4.12.
• Pass: on Windows 2025, setup-ruby resolved '3.4' to 3.4.11.
• Failed, then fixed: setup-ruby v1's Windows table has no 3.4.12, which release.yml's build-windows would have asked for. The release.yml commit fixes it.
• Not run: main.yml (this PR runs it) and release.yml, which a dry_run dispatch would check.

Design Review

No frontend files changed, so design review was skipped.

Eval Results

No prompt-related files changed, so evals were skipped.

Scope Drift

Scope Check: CLEAN. The one incidental change is the Gemfile.lock platform line, committed on its own.

Plan Completion

Plan completion audit: not run (no plan is bound to this branch and no docs/designs/ file matches). Fix: add "Plan: " to the PR body, or run /autoplan.

Verification Results

No plan-specific verification items.

Watch in this PR's run:

• ruby-test: the appraisal gemfiles say BUNDLED WITH 2.6.8, and they now run on a new image and patch.
• The package-manager '4.0' legs: they now resolve to 4.0.9, published today.
• first-run, bun-test and rubocop: the canary covers none of these.

TODOS

No TODO items completed in this PR.

Documentation

Status: current. No documentation edits were needed.

Scope: the branch diff against base 1001765 (three workflow files pinning ruby/setup-ruby to the '3.4' series) plus the unstaged .ruby-version (3.4.8 to 3.4.12), AGENTS.md (the matching Ruby version line) and Gemfile.lock (an added arm64-darwin-27 platform). I inventoried every authored doc and read AGENTS.md, README.md and the consumer guide's CI snippet against these changes.

Documentation health:

• AGENTS.md: current, and its 3.4.12 line matches .ruby-version.
• README.md: current, since it says Ruby 3.4 or newer and the Docker examples use the 3.4 series.
• docs/guides/rubygem_npm_dependencies.md: current, as its setup-ruby snippet is for consumer apps.
• docs/AUDIT.md and docs/plans/*: historical records, left untouched.
• CLAUDE.md, CODING_STANDARDS.md and docs/agents/*: reviewed, no change needed.

Coverage debt: AGENTS.md's CI section does not note that every setup-ruby step pins '3.4' (optional, not added). Diagram drift: none.

Test plan

• bin/test-all under Ruby 3.4.12 (compile, Go, Ruby with STAGE_A=1, Bun): all ok; 812 runs, 0 failures, 0 errors, 7 skips
• gh workflow run canary.yml --ref ci/ruby-3.4-series: 6/6 jobs green, with Ubuntu on 26.04 / Ruby 3.4.12
• jactionlint on the three workflows: no new findings (release.yml's 7 cache-poisoning errors are on master too)
• main.yml on this PR
• gh workflow run release.yml --ref ci/ruby-3.4-series -f dry_run=true
