EEGT v0.3.0 — Continuous EEG and transition geometry

EEGT now includes the full pinned around-ear corpus: 55 source recordings, 54 qualified, and 223.47 decoded sample-hours. The run analyzed 1,608,671 multichannel windows; 1,077,399 passed the engineering quality gate. One source remains quarantined and visible.

Three numerical views locate partly overlapping transitions. On 16 previously unused external records, median timing F1 is 0.487 for shape/spectrum, 0.245 for shape/coordination and 0.207 for spectrum/coordination. These are timing agreements, not diagnostic accuracy or proof of universal geometry. Phase and nuisance controls, all selected scales, per-record results and five geometry descriptors are retained.

Assets:

• eegt-v0.3.0-database.tar.gz: source and transition SQLite databases, source/protocol/model/control/transfer receipts, per-record results and notes.
• eegt-v0.3.0-features.tar.gz: 54 numeric feature files and their binding receipt. Extract both archives into the source checkout to inspect the full derivative database.
• eegt-v0.3.0-database-manifest.json and SHA256SUMS-v0.3.0.txt: per-file and archive identities.

Original 21.54-GB raw files remain at the public archives with a pinned, checksum-verifying downloader. Code is MIT; the derivatives of these CC0 datasets retain upstream attribution. No private recordings are included.

Validation: 44 tests and 2,412 numerical/source-join audit checks pass locally and in a separate review environment. GitHub Actions did not run because the organization disables it. Physical Neurable collection, independent pretrained-LLM discovery, repeated-session reliability and clinical/semantic claims remain unverified. Earlier releases are preserved.
