Corrections · Edition history

A changed claim needs a visible reason.

This collection is published as dated research editions. The cutoff tells you when research stopped; individual sources and observations retain their own dates. A new source does not silently turn an old forecast into an achieved result.

Propose a correction

Use the Program Receipts source repository’s issue tracker. Identify the program and edition, the exact disputed sentence or data record, the proposed correction, and a primary-source URL with its page or paragraph locator. Distinguish a factual error from a new event after the edition’s cutoff.

For corrections or questions, email support@programreceipts.com. The repository is an alternative and may require access. Please identify the page, the claim and a public source supporting the correction. This site has no submission form or response-time commitment; do not send private records, credentials or nonpublic information. The edition history below remains readable without repository access.

How revisions are labeled

Material factual corrections record the old claim, corrected claim, reason and date in the program’s edition history and the repository change log. Substantive new source review gets a dated edition with its own cutoff. Presentation-only changes are identified as such and do not imply renewed factual review. Prior releases and source-control history preserve reviewable earlier text; this policy does not claim multiple public releases existed before the first publication.

Collection history

September 24, 2026 · Collection edition 1.1

• Added Sentinel edition 1.0, cutoff 10:55:44 UTC: original commitments, the cost breach and reset, changed flight-test scope, selected funding/contracts and reported 2026 results.
• Added the short brief, full PDF, historical constant-dollar chart, source/claim data and reproducible calculations. The July 2024 estimate remains separate from the comparable historical series.
• Updated collection navigation and the offline bundle. MQ-25 and KC-46A reports, data, PDFs and factual cutoffs remain unchanged; their pages receive navigation-only changes.
• No live monitoring, automatic research, other-site work or independent human audit is implied.

September 12, 2026 · Collection edition 1.0

• Added the programreceipts.com collection home, methods, shared source navigation and corrections history.
• Retained the complete MQ-25 edition 1.0, evidence cutoff 15:30 UTC. Its page now lives at MQ-25; the factual narrative, original/revised baselines and evidence boundaries are preserved. Collection navigation and publication wording were adjusted.
• Added KC-46A edition 1.0, evidence cutoff 16:07:30 UTC. It distinguishes the original RAA package, later IOC declaration, dated deliveries, operating limits and future fixes.
• Added portable PDF/Markdown/JSON downloads and domain metadata. Website/domain deployment is separate from preparing this edition; this history does not assert that DNS or hosting was already activated.

No factual correction was recorded in the first collection edition. Its review notes were the producing research review plus executed verification, not an independent audit. Sentinel was outside that edition; its later completed record is dated separately above.
