Perform a new independent IMPLEMENTATION and merge-readiness review for R7, not another plan approval. User explicitly requests real "opus 5 max" verification and authorizes merging main only if correct. Do not edit files or attempt Write, do not make any network mutations or claim tests you did not run. Return review text only.

Source hashes and full local test evidence: /Users/vonng/.codex/worktrees/ad51/silo/docs/investigations/r7/verification.json
Caller just recomputed all four code hashes and previous validation log hashes: all match. No source changes since tests passed. The prior evidence includes 80 focused cases, existing SSE-C and trust/poisoning/trailer/Snowball regressions, race, make verifiers and build. Capacity adaptation is explicit, temporary, and real storage I/O still runs. Exact baseline counterfactual: same final tests, old product extractor, 44 controls pass/36 fail. Review logs are available at /Users/vonng/tmp/silo-r7-20260915-ad51/ and permitted via add-dir.
Read the complete actual diff and relevant current call sites/source/tests. Prior agreed plan: docs/investigations/r7/plan-v1.md; prior dispositions and final Opus agreement: plan-v1.dispositions.md and review/opus-v1-confirmation.md. Treat them as context, not a reason to rubber-stamp implementation. Production change adopts PR #187, with only a clarified Snowball comment; candidate also adds stronger tests and documents. PR #187 head remains b8f2fdde41 and unmerged; its checks were awaiting outside-contributor workflow approval, not successful CI.
Assess correctness, unintended regressions, trust boundary (PUT/COPY/MPU/Snowball), six SSE metadata fields including empty marker/checksum, request-body signature handling, GET/HEAD/raw-byte expectations, whether tests actually exercise promised paths, and whether capacity fixtures or evidence fail to justify the narrow fix. Inspect especially Snowball ordinary-vs-replica parity, source polluted-metadata limitation, exact token whitespace behavior, and raw ordinary metadata redaction. Do not broaden to R4/R5/R8 or claim full distributed testing. Identify real merge blockers with file/line/evidence and smallest repair; separate optional improvements.
Intended integration: publish this complete reviewed local branch to a normal pgsty/silo PR, wait for its applicable CI, and merge into main. This includes the originally credited PR #187 implementation plus local tests/docs. Do not mutate the original contributor's branch. If main advances first, inspect integration delta, revalidate necessary tests and review again if relevant behavior changed. Merely adding this review report changes documentation only. Merging main is now explicitly authorized by the user, superseding the earlier workflow's no-merge boundary; no release/deploy/live object rewrite is authorized.
Return in Chinese: exact reviewed candidate/base/hash; APPROVE / APPROVE_WITH_NONBLOCKING_NOTES / REQUEST_CHANGES; each blocking finding and optional note; what you inspected vs trusted as supplied test evidence; and explicit whether this exact code may merge once CI is verified. Be concise but evidence-based. No model substitution, no fake test execution.
