Location: [private Drive store] (Drive-hosted; local staging copies are deleted after MD5 verification per the user retention instruction of 2026-09-24).
Contents: 82 checksummed data products (1112.1 MB), 132 manifest rows (including probe/exclusion records), from all 8 anonymous-access deep-sky archives of DATA_SOURCES.md §1. Built by cygnus.ingest.tier1 on 2026-09-23/24. Every data product above was MD5-verified against the Drive copy before its local staging copy was deleted.
Provenance: every product is checksummed (sha256 + md5), carries its exact endpoint URL and verbatim query, and is registered in the worktree ledger (state/ledger.sqlite; CSV export PROVENANCE_ledger_products.csv). Any product can be re-fetched from its recorded URL.

See SEARCH_LOG.md for verified data gaps (they are recorded, never hidden) and DATA_SOURCES.md §0 for the live-verified service quirks this build relied on.
The separately developed read-only research pilot in src/cygnus/analysis/ and notebooks/cygnus_reanalysis_colab.ipynb is described in docs/ANALYSIS_SUITE.md. It checks SHA-256 before loading a selected file and does not mount or inspect Drive on its own. This document's product totals reflect the recorded pack build, not a fresh Drive inventory; a Colab account's mount permissions must be verified separately. The chosen targets are benchmark examples rather than an exhaustive or previously unsurveyed sky sample.
