## Music genre test publication

Published the first policy-compliant test genre record at [Sumerian hymnody](mark://music/genres/sumerian-hymnody.md). It uses EDTF `-2XXX` for third-millennium BCE precision and remains `status:imported` pending library review.

## Music genre body cleanup

Revised [Sumerian hymnody](mark://music/genres/sumerian-hymnody.md) to version 2 under the updated music policies. Operational identity and import fields now live only in metadata; the visible body contains genre information and sources.

## Chronological genre catalog

Published [Ershemma](mark://music/genres/ershemma.md) after user approval, continuing the catalog by documented attestation. Its metadata keeps attestation separate from inception because a dated surviving tablet does not establish invention. Operational details remain separate from the readable genre body.

## Genre batch workflow

The user approved the readable genre format and authorized publishing subsequent chronological batches without another format-confirmation step. They want each period handled as a batch rather than one selected example. Coverage must still remain evidence-bounded, with unresolved candidates carried forward instead of treating a period as globally complete.

The current batch and its open coverage questions are authoritative in [the early second-millennium manifest](mark://music/genres/manifests/early-second-millennium-bce-2026-10-06.md). Batch-selection dates are not inception dates; generated era views should not turn corpus attestation into an emergence claim. The [genre catalog](mark://music/genres/index.md) now provides generated browsing views.

## Next chronological window

The user explicitly requested advancement to the next era without another format confirmation. Advancing the selection window does not mark the previous window’s unresolved research complete. The latest authoritative publication and its evidence limits are in [the Late Bronze Age manifest](mark://music/genres/manifests/late-bronze-age-2026-10-06.md); browse through [the genre catalog](mark://music/genres/index.md).
