This addendum records a targeted read of the corrections, not a new blind review.

CH1 RESOLVED. I read the revised source-provenance passages of the report and
the full revised article. Both now disclose the atmospheric curve's scaling
and digitization, with exact handling unresolved. The report also identifies
the author-hosted-v4/editorial-note limitation. Neither claims that scaling
necessarily invalidates the historical regression. The narrower source-chain
finding remains defensible.

CH2 RESOLVED. Report §7 now calls GCB historical values “estimates”.

CH3 RESOLVED. Claim ledger C08 now says the author package was “not located”,
consistent with the report's bounded public-search limitation.

No unresolved substantive objection to the narrowed scientific disposition
remains from this challenge. This is scientific/editorial readiness within the
declared limits, not authorization to publish or a complete attribution study.
