🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Return utf8Valid when both options are enabled.
A caller can set reportUtf8Validity: true and fatalUtf8: true. For a valid body at EOF, this condition skips the reporting branch and returns utf8Valid as undefined. This conflicts with the BoundedBodyResult contract at Line 49.
When validity reporting is requested, return utf8Valid: true after a successful fatal decode. Keep fatal decoding for malformed input.
Proposed fix

- const decoded = decodeUtf8WithValidity(retained.subarray(0, retainedBytes));

A caller combining reportUtf8Validity with fatalUtf8 got no utf8Valid field for a valid body at EOF, breaking the BoundedBodyResult contract. The reporting branch now runs whenever reporting is requested: a successful fatal decode already proved validity, while malformed input still throws.
|
Addressed the combined-options finding in f7f5b4b: the EOF reporting branch now runs whenever reportUtf8Validity is set. With fatalUtf8 a successful decode returns utf8Valid: true; malformed input still throws with the decode discriminator. Added coverage for both. bun test tests/server/bounded-body.test.ts: 35 pass. |

Consolidated into #5553 as a single related-function aggregate. Source head: Both source commits are fully retained: 3a122d0 as f732aa4, and the EOF review follow-up f7f5b4b as 6e6bd22. Their complete stable patch IDs match, author/date/source-SHA attribution is preserved, and the two runtime files plus the quota and bounded-body regression files remain byte-identical to the completed carry. The cyber-policy test preserves every existing line and adds one import and one combined regression; that file is not byte-identical. Malformed UTF-8 preserves cyber-policy stop classification while complete valid UTF-8 remains mandatory for quota evidence; the fatal-decode plus validity-reporting EOF regression is included. A new combined regression also covers policy stop plus the current dev non-replayable marker. The replacement documents the seven-file 362-pass/1-fail sample, the corrected Kiro fixture's separate pass and its subsequent sibling/layout pass accurately; it does not claim a full green rerun. TypeScript, structure, privacy and unchanged size-cap checks passed. Exact-head hosted CI and security review remain on the draft replacement. This closes only the fully migrated #5307; the partial #5310 is not being closed. Closing this duplicate standalone review entry as part of the requested consolidation after verifying coverage. This is not a merge or release claim; remaining integration checks and reviews are tracked on the replacement. Original branches are retained. |

Summary
consumeComboFailurepassedfatalUtf8for 5xx bodies, so a single malformed byte rejected the entire read and erased an otherwise-classifiable cyber-policy stop.readBoundedResponseBodygainsreportUtf8Validity: the body is decoded with replacement characters while the result reportsutf8Valid. Quota evidence on a 5xx now requiresutf8Valid === true; every other classification — notably cyber-policy failures, which must stop — still uses the bounded decoded text.Verification
