Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 WalkthroughWalkthroughProduction rendering now selects a release-specific hydration runtime from immutable build artifacts. HTML, page, snippet, and static asset paths carry release and output-directory metadata. Tests cover runtime selection, asset isolation, deployment contracts, and browser hydration. ChangesRelease Asset Rendering
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This PR binds hydration HTML to release-specific runtimes, but the current implementation can still fail standalone rendering with a stale output directory, mis-handle certain filesystem errors, and omit important Node/Bun test coverage.

I found no blocking issues. The reviewed paths select the release-baked runtime from the configured output directory. Component, script-page, and snippet shells use the selected path. Component module preload and execution use the same path. The code fails closed for missing or ambiguous release artifacts. Full-document component rendering does not load the hydration runtime. I did not execute repository tests in this inspection environment.

Inline comments:
In `@src/html/hydration-script-builder/prod-runtime-selection.ts`:
- Around line 55-67: Update the selectedPath === null handling in the release
hydration runtime selection flow to return getProdHydrationModulePath() when
options.releaseId is "standalone-dev", matching the existing missing-directory
fallback; preserve RENDER_ERROR for other release IDs.
- Around line 40-61: Update the error check in the runtime-directory inspection
to rethrow only errors that are instances of VeryfrontError with the expected
render-error slug, rather than relying on a slug property alone. Move the
multiple-runtime ambiguity throw out of the try block by recording the selected
candidate during iteration and raising the render error after the try/catch
completes.
In `@src/rendering/snippet-renderer.test.ts`:
- Around line 58-64: Move the Deno.mkdir and Deno.writeTextFile setup calls into
the existing try block so failures during setup still reach the finally cleanup
for projectDir; keep the temporary-directory creation and test behavior
unchanged.
In `@src/server/handlers/request/static.handler.test.ts`:
- Around line 78-107: Replace the direct Deno filesystem calls in the new
StaticHandler test with the runtime-neutral utilities from
`#veryfront/platform/compat/fs.ts`, including temporary-directory creation,
directory/file operations, and cleanup. Keep the test in static.handler.test.ts
so all StaticHandler tests remain included in Node and Bun runners.
Apply the same fix in
`@src/html/hydration-script-builder/prod-runtime-selection.test.ts` around lines
57 - 73: The same direct Deno-global pattern excludes the new runtime-selection
tests from Node and Bun.
In `@tests/e2e/regressions/2026-07-27-legacy-router-hydration.test.ts`:
- Around line 266-300: Update the Deno.serve request handler in the hydration
test so unmatched JavaScript requests return valid JavaScript with an
appropriate JavaScript content type instead of an empty 204 response. Keep the
agedRuntimePath response, production hydration module request tracking, and
empty-diagnostics assertion unchanged.

Nitpick comments:
In `@docs/guides/deploying.md`:
- Around line 37-41: Clarify the final verification sentence in the deploying
guide by explicitly stating that the build output directory contains the browser
assets and that API routes, agents, workflows, and tasks remain in the project
source before uploading source.
In `@src/html/hydration-script-builder/prod-runtime-selection.test.ts`:
- Around line 119-131: Add a test case for standalone-dev serving with an
existing readable dist/_veryfront directory that contains no content-addressed
runtime, exercising resolveProdHydrationModulePath and asserting the expected
successful fallback behavior instead of the current throw.
In `@src/html/hydration-script-builder/prod-runtime-selection.ts`:
- Around line 36-69: Memoize the release runtime selection around the
directory-reading logic, keyed by projectDir, buildOutDir, and releaseId, so
repeated production renders reuse the selected path without another readDir
call. Preserve the existing error handling, standalone-dev fallback, and missing
or duplicate runtime validation; follow the caching approach used by
getProdHydrationModulePath.
- Around line 16-34: Use the same release-presence predicate in
hasImmutableReleaseHydrationRuntime and resolveProdHydrationModulePath so
empty-string release IDs have identical behavior in both APIs; update the
resolveProdHydrationModulePath guard to rely on the shared predicate rather than
a separate truthiness check.
In `@src/rendering/script-page-handling.test.ts`:
- Around line 122-135: Refactor renderWithPageRenderer to accept a single
options object containing the existing projectDir, pagePath, dependency pinning,
releaseId, adapter, and config values. Update all call sites to use named
properties instead of positional arguments and remove undefined placeholders,
preserving the current defaults and behavior.
In `@src/rendering/script-page-handling.ts`:
- Around line 277-284: Update the fallback in the prodHydrationModulePath
assignment to call getProdHydrationModulePath() directly instead of
resolveProdHydrationModulePath without a releaseId, while preserving the
production-mode condition and releaseHydrationModulePath precedence.
In `@src/server/services/static/static-file.service.test.ts`:
- Around line 345-414: Update the test covering absolute build output to also
resolve "/src/private.js" with the same absolute buildOutDir and assert that the
result is null, proving project files are not exposed through that boundary.
Move the existing buildOutDir: "." malformed-root assertion into a separate it()
test with its own setup as needed, keeping each test focused on one containment
behavior.
In `@src/server/services/static/static-file.service.ts`:
- Line 163: Extract the repeated build output root calculation into one private
helper in the static file service, preserving the existing
resolve(options.projectDir, options.buildOutDir || "dist") behavior. Replace the
occurrences near the secure filesystem boundary, candidate-root handling, and
manifest cache key with calls to that helper so all consumers use the identical
root.
In `@tests/e2e/regressions/2026-07-27-legacy-router-hydration.test.ts`:
- Around line 263-264: Replace the boolean HTML checks in the regression test
with assertStringIncludes from `#veryfront/testing/assert.ts`, importing it
alongside the existing assertions. Preserve the agedRuntimePath inclusion
assertion and express the getProdHydrationModulePath exclusion using the
assertion library’s supported negation form.

I found no blocking issues. The runtime resolver now reports ambiguous release runtimes after directory inspection.

Immutable release HTML must load the hydration runtime produced with its pinned browser artifacts. Select that content-addressed runtime across component, script-page, snippet, and full-document rendering, while preserving standalone source serving on the current RSC boot path. Serve configured relative or absolute build outputs through separately scoped filesystem roots so the selected runtime remains reachable without widening project access. Constraint: Immutable release browser artifacts and their hydration runtime form one compatibility unit. Constraint: Standalone source serving must not depend on stale or missing build artifacts. Rejected: Serve the current process runtime for every release | recreates cross-version export skew. Rejected: Add release-specific public URL namespaces | unnecessary because content-addressed filenames already avoid collisions. Confidence: high Scope-risk: moderate Reversibility: clean Directive: Do not bypass release-aware runtime selection in new HTML shell paths or broaden configured build-output filesystem roots. Tested: Focused Deno matrix 6 tests/119 steps; aged-release Chromium 2 steps; focused Node and Bun resolver/static-handler suites; npm build; typecheck; lint; format; anti-slop; test-typecheck; diff check. Not-tested: Production cloud artifact-retirement operations remain an external lifecycle concern. Related: veryfront/veryfront-issue-inbox#277

I found no blocking issues. The runtime resolver selects exactly one versioned runtime for immutable releases. It fails closed for missing, unreadable, and ambiguous release artifacts. Non-release renders and Component, script-page, and snippet rendering propagate the selected runtime. The shell uses that same path for the production script and module preload. Static serving uses separate scoped filesystem roots for the configured output directory and project files. The containment check prevents an output root that contains the project from exposing source files.

Summary
This implements option 1 selected in veryfront/veryfront-issue-inbox#277 and builds on the content-address ownership fix in #3807. It addresses the artifact skew exposed by incident veryfront/veryfront-issue-inbox#264 and the compatibility hotfix in #3124.
RED / GREEN
RED coverage reproduced current-runtime leakage from aged release component HTML, wrapped and full-document JavaScript pages, snippet shells, and full-document components. Additional regressions reproduced the missing server release handoff, standalone development misclassification, configured output-directory 404s, and absolute external output rejection.
GREEN coverage verifies:
