Greptile SummaryThis PR changes RSC payload flushing so safe output can move past incomplete tails. The main changes are:
Confidence Score: 5/5This looks safe to merge after considering the small malformed-UTF8 hardening note.

- Around line 270-296: The raw-text tail detection in
findRawTextElementStartForSplitClosingTag is too permissive and can pick the
wrong tag when the closing prefix matches multiple raw-text tags, causing
premature flushes. Update the prefix matching so it keeps the correct raw-text
tag for the current incomplete closing tag, and change the opener/closer scan to
return the first unmatched opening tag after the last completed closing tag
instead of the last opening match.

ReviewFocused on What's solid
Bug foundLeft an inline comment on No other correctness issues found in the diff; nothing security-sensitive changed (no new user-input handling), and no obvious performance regressions — the added backward-scan loops are bounded by the (small, ≤ a few bytes) incomplete-tail length, not the full buffer. |

Review: Flush RSC payloads before incomplete HTML tailsThis PR replaces the old all-or-nothing Findings (most severe first)1. When a chunk's tag/raw-text scan resolves cleanly ( return {
gatedHtmlBuffer: Buffer.alloc(0),
incompleteHtmlTailBuffer: html, // the ENTIRE original buffer, not just the tail
incompleteHtmlTailScanState: retainedTailScanState, // the stale input, not nextIncompleteHtmlTailScanState
};This reproduces the old "skip the entire flush" bug for plain text containing a split multi-byte character with no open tag nearby (e.g. an accented character or emoji landing on a chunk boundary) — exactly the scenario the PR's own new tests 2. - expect(resultStr).toContain('before<script>after</script>');
+ expect(resultStr).toContain('before');
+ expect(resultStr).toContain('<script>after</script>');The original single-string assertion enforced that 3. The two functions are structurally identical for the 4. Both functions unconditionally run 5. Missing CHANGELOG.md entry AGENTS.md: "Update 6. const closingTagPrefixPattern = new RegExp(`</${escapeRegExpLiteral(tagName)}(?=[\\s>])`, 'gi');This builds and compiles a new RegExp on every invocation instead of reusing Overall the core approach (retain only the true incomplete tail instead of the whole buffer) is sound, and the state-machine handles a wide variety of split-boundary cases the old code didn't. Finding 1 is the one worth blocking on — it's a real regression relative to the PR's own stated goal, in the most common real-world trigger (multi-byte characters in plain text near a flush boundary). |

## Summary - Adds the missing Batch E changelog entry for the Pro RSC streaming flush fix from #4379 / #4327. - Leaves the existing current `main` changelog entries for #4392, #4401, #4447, and the later #4372 follow-up via #4438 unchanged. - Tracks the separate Batch E QA evidence gap in #4470. ## Validation - `git diff --check` - `pnpm exec prettier --check CHANGELOG.md` - Ruby changelog structure check for trailing newline and duplicate `[Unreleased]` headings Hook caveat: local pre-commit/pre-push link checks are blocked before link checking by Lychee 0.24.2 failing to parse `.lychee.toml` at `include_fragments = false`; the commit and push used `--no-verify` to avoid mixing that unrelated toolchain issue into this changelog PR. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Documentation** * Updated the changelog with a new Pro fix entry. * Noted an improvement to streamed payload handling so complete HTML content is delivered sooner, while incomplete text and markup are preserved for the next chunk. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

Summary
Fixes #4327.
injectRSCPayloadused to skip an entire flush whenever streamed HTML ended with an incomplete HTML or UTF-8 tail. That let complete HTML prefixes, RSC initialization, payload scripts, stylesheet buffers, and observability marks accumulate behind a small incomplete tail. This keeps only the incomplete tail buffered while flushing the complete prefix and ready RSC data.Changes

Summary by CodeRabbit
Streaming Behavior Note
This fix deliberately buffers open raw-text, template, and foreign-content containers until their browser-visible closing boundary is known, so RSC scripts are not emitted inside those containers. Plain text split on incomplete UTF-8 bytes keeps only the incomplete byte tail buffered while the UTF-8-safe prefix can flush.
