ci: one JRuby cell instead of five - #295
Conversation
Reviewer's GuideCI now uses a lightweight critical path for pull requests, a six-cell Ruby/Rails spanning set plus cuprite screenshot coverage as the master gate, and non-gating weekly jobs to exercise skipped Ruby/Rails pairs, all browser drivers, and forward-looking runtimes while documenting the tradeoffs and maintenance contract.

📝 WalkthroughWalkthroughThe workflow replaces broad pull request test coverage with a spanning-set gate. It retains broader coverage for master, scheduled, manual, and ChangesCI coverage and documentation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to Weekly drift failures currently may finish without preserving failure screenshots, making regressions harder to diagnose.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Upload failure artifacts from matrix-drift.
When a matrix-drift cell fails after its retries, the job ends without an artifact upload. drift-drivers preserves failure screenshots, but this job does not. Add an if: failure() upload step after this retry step. This preserves diagnostics and meets the stated drift-job contract.

Master run ~130 min -> ~79. JRuby was 56% of the bill: five cells at ~15 min proving the same JVM facts (no Kernel#fork, thread semantics, the FFI/vips path), none of which vary by Rails version. Dropped from `ruby-version`; one jruby-10.1 cell in `include`. MRI grid untouched -- ~4 min a cell, so cutting them buys little. Restores 4.0 x rails81: its exclude claimed functional-test covered it, but that job runs the pair on vips and the matrix runs chunky_png. Comments trimmed to why-only, 62 lines -> 20. Two were stale: the matrix was described as a spanning set, and 4.0 x rails81 as absent.

Streamline CI by replacing redundant JRuby matrix cells with a single representative cell, restoring Ruby 4.0/Rails 8.1 coverage, and limiting full-matrix runs to intentional gates.
