Big Tech Silent Adoption Exposure – Ceiling Truth Engine (CTE) / ILPNP Provenance Baseline

This record contains immutable, blockchain-anchored proof that two major AI teams — Google DeepMind and Microsoft/GitHub — are quietly stress-testing the CTE/ILPNP provenance baseline in their own systems. The provenance baseline sequence is: SHA-256 manifest OpenTimestamps (OTS) receipt(s) anchored in the Bitcoin blockchain Persistent identifier (DOI) or equivalent public resolver Replayable verification steps for independent validation This sequence is documented in prior DOI records: • 10.5281/zenodo.16929003 • 10.5281/zenodo.16929102 • 10.5281/zenodo.16929602 • 10.5281/zenodo.16930543 • 10.5281/zenodo.16931051 Key facts: • All artifacts in this record are sealed with SHA-256 and OTS receipts, making alteration or misattribution impossible without detection. • Multiple public and internal materials now mirror this exact 4-step sequence under alternative terminology (“immutable registration,” “internal timestamp service,” “time anchoring”), confirming silent adoption. • This package serves as a global chain-of-custody entry, ensuring that any future public use without attribution can be exposed with side-by-side hash tables and timestamps. Notice to named entities: If this sequence is deployed publicly without credit (“Ceiling Truth Engine / ILPNP provenance baseline, Daniel Eduardo Campos Peñuelas”) and preservation of proofs, a full exhibit set will be published. That set will contain timestamped mirrors of the derivative artifacts, linked to the originating DOIs, and will be mirrored across multiple archives. Verification steps: Download the included manifest/checksums and OTS receipts. Run: ots verify <receipt>.ots Match all listed SHA-256 hashes to confirm byte-exact preservation.
