Small-body catalog release 2026.10.10.1

Publication and activation were verified on October 12, 2026. This is a data release, independent of the engine/PyPI version (production engine: 6.9.9). The public ephemerides page exposes the current catalogs, adaptive policies, receipts and historical downloads.

The packaged metadata-only manifests and canonical identity receipts now bind these exact releases. Identity registries and aliases have not changed; BSP data remain external, except for the unchanged 25-body asteroid wheel catalog moira-asteroids-wheel@2026.08.14.1. Known identity is not installed position capability. This source alignment does not itself publish a new engine wheel.

Sampling and source freshness

• Asteroids: ten-day/seven-node base, with certified adaptive apsidal refinement for the 59 audited bodies in 40 rebuilt shards. The other 409 shards are byte-identical and were hash-verified on the server before hard-link reuse. Policy: moira-small-body-type13-apsidal-adaptive-v4.
• Comets: the same base, with certified adaptive apsidal refinement for all 497 admitted trajectories. Policy: moira-comet-type13-apsidal-adaptive-v5. The final October 11 source-solution census checked all 497 bodies; 38 were refreshed and 459 segments remained byte-identical.
• Local refinement starts at one day and is halved as necessary. Policy floors are 1.5 hours for repaired asteroids and 11.25 minutes for comets, not uniform spacing throughout the catalogs. Certification compares half-step witnesses under unchanged 8.64 s event-time and 1e-9 AU radial-distance gates. Failure requires finer sampling or rejection, not wider acceptance gates.
• Comet refinement queries are bounded to 32 Julian years with integration anchors. Coverage and target solutions remain manifest-declared; nongravitational-model and distant-apparition limitations are not removed by better interpolation.

Validation scope and preserved evidence

Final sealed-release integration checked native state/element, coverage, identity and provenance invariants for all 11,720 bodies; four frozen asteroid element holdouts; six anchored asteroid apsidal events; and three anchored comet events with Halley JPL#75 and Encke JPL#K273/22. The largest comet timing residual was 0.000603497 s, inside the unchanged 8.64 s gate.

All-body structural/provenance checks and adaptive internal convergence are not an independent all-body/all-epoch JPL accuracy guarantee. The selected external event comparisons do not claim that wider coverage. Scientific validation/support files are byte-bound in each release manifest and its SHA256SUMS; for example, the comet manifest includes validation/current-comet-anchored-oracle/report.json and source_review.json.

The original September 28 element/node admission, holdouts and scientific tolerances remain immutable. Its exact September asteroid and July comet manifests are archived in tests/fixtures/small_body_release_manifests. Those historical authority results are not relabelled to admit different catalog bytes or Encke’s newer solution. No new historical geometric-node oracle sweep is claimed by the October release closure.

Publication boundary

Server publication at 2026-10-12T16:14:02Z verified staged/live release identities, public manifests and checksums, selected BSP byte ranges and production readiness. An independent live receipt at 16:21:47Z confirmed both manifest hashes and served small-body identities. Existing planetary bindings were preserved: DE440 facade, DE441 server fallback and DE441 Workspace API. The unrelated Jupiter result remained unchanged.

Prior catalogs were retained: asteroid 2026.09.18.1 and the raw comet rollback directory rollback-raw-20261012. No ephemeris files were deleted. The ephemerides website update was subsequently staged and promoted from the same verified artifact; historical downloads were preserved. Catalog publication did not modify the unrelated Vedic work.
