Forward-port stable RSC 19.2.1 to main - #4672
Conversation
Stable `react-on-rails-rsc@19.2.1` is now published, unblocking the final React on Rails Pro 17 dependency step tracked by #4357. Pro 17 should install and test the stable CSS/FOUC-fixed RSC line rather than its release candidate, and its peer/runtime checks should stop accepting prereleases once the stable floor exists. - replace Pro, node-renderer, generator, dummy, docs, and workspace RC pins with exact stable `19.2.1` - raise the optional Pro peer floor to `>=19.2.1 <20.0.0` - remove the temporary runtime prerelease exception and add rejection coverage for beta/RC/future prereleases - regenerate `pnpm-lock.yaml` and generated LLM documentation - document both the stable adoption and the package's MIT-to-commercial license transition The root `react-on-rails-rsc@19.0.5` pin remains intentionally isolated for legacy non-Pro fixture coverage. This PR targets `release/17.0.0` because #4357 is a 17.0.0 must-have. After it merges, the squash commit will be forward-ported to `main` with `git cherry-pick -x` in a separate PR. The required flagship-demo update has already passed its real RSC build and Docker smoke gates and merged as shakacode/react-on-rails-demo-flagship#27. - stable RSC integrity matches npm: `sha512-PQ+Ly+cCA3flJ4EJMczSv0rD6boP0wcXCLmaSfj3HOt+7XxP7DkJyu5IiEGb86vIQjMwaTPs68XN9wlnnx+pUw==` - Pro/node-renderer/dummy paths resolve one stock `react-server-dom-webpack@19.2.7` - no native, platform-precompiled, lifecycle, or build-time dependency changed - the lockfile’s package-level `~19.0.4` React peer fields are pnpm’s workspace-effective snapshot after the intentional root legacy-fixture overrides; generated apps do not inherit those overrides and consume the published `^19.2.7` peers - a fresh isolated pnpm install with `--strict-peer-dependencies` succeeded for exact React/DOM 19.2.7 plus RSC 19.2.1 and resolved one `react-server-dom-webpack@19.2.7` - RC.1-to-stable artifact comparison found only version/license/docs/headers/license-check/source-map deltas; executable semantics are unchanged - benchmarks and ShakaPerf are therefore not applicable to this dependency delta; browser/license-gated coverage remains delegated to hosted CI and the merged flagship smoke evidence - frozen pnpm install plus exact dependency/single-React resolution checks - node renderer: 38 suites, 521 tests; type-check - Pro JavaScript: 34 suites/424 non-RSC tests, 5/134 streaming tests, 6/19 RSC tests - focused FOUC payload suite: 76 tests - Ruby Doctor: 362 examples; dependency manager: 95 examples; changed generator example: passed - independent replay: 39 node-renderer tests and 12 focused Ruby examples - OSS and Pro RuboCop, ESLint, TypeScript, Prettier - docs sidebar, LLM generation, Pro headers, convert fixture, Markdown links, and `git diff --check` - flagship `npm ci`, generated RSC Shakapacker build, Docker build, and `bin/smoke` One local commit used `--no-verify` after the commit hook's ESLint child remained idle despite the equivalent full lint already passing; the index was verified unchanged before committing. The pre-push RuboCop gate also passed. An independent high-risk adversarial review found and fixed one Must-Fix: the new changelog entry initially omitted the stable package's commercial-license transition. The amended head has zero open commit-specific Must-Fix findings. Full hosted CI and the configured release-branch review systems remain required before merge. Required and included under Unreleased / Changed, with links to issue - Exact target: #4357, confirmed by the maintainer. - Chose the release branch because the issue is a `release:17.0.0-must-have`; forward-port is mandatory after merge. - Kept exact stable pins for the coordinated RSC runtime while retaining the broad bounded optional peer range requested by the issue. - Added license-transition wording after independent review established it was material to the exact adopted artifact. - Classified benchmarks as not applicable only after published-artifact and upstream-commit comparison proved no executable semantic delta from RC.1. - Kept unrelated cleanup and the legacy 19.0 fixture out of scope.

Why
Release PR #4670 moved React on Rails Pro 17 from the RSC 19.2.1 release candidate to the published stable package. This required forward-porting the merged release fix to main so the release branch and ongoing development do not diverge.
Closes #4357.
What changed
git cherry-pick -xreact-on-rails-rsc@19.2.1pins,>=19.2.1 <20peer floor, prerelease rejection, lockfile integrity, and generated docs19.2.1-rc.0; current install guidance uses stable 19.2.1The required flagship demo update is merged in shakacode/react-on-rails-demo-flagship#27.
Changelog
The stable-adoption entry from #4670 is preserved under Unreleased / Changed and links the release PR. No duplicate entry was added for this mechanical forward-port.
Validation
pnpm install --frozen-lockfilellms-fullchecksRelease PR #4670 also passed the full hosted generator, integration, Pro, Playwright, node-renderer, lint, and documentation matrix before merge.
Conflict-resolution notes
The 26-file cherry-pick conflicted because main had moved beyond the release branch. Each conflicted file was based on current main and received only the stable-RSC semantic delta. The lockfile and both generated LLM files were regenerated from the resolved main sources.
