+# AGGS GitHub structural corpus
+
+This snapshot supports repository discovery and dependency-graph navigation
+without redistributing source content. Its manifest records the exact build ID,
+schema version, artifact hashes, byte sizes, row counts, and audited structural
+symbol count.
+
+## Contents
+
+- canonical GitHub `owner/repository` and PyPI package identifiers;
+- typed package/repository/native dependency relations and numeric evidence;
+- repository-relative source paths;
+- qualified symbol names and symbol kinds; and
+- whitespace-normalized signatures capped at 1,024 UTF-8 bytes.
+
+The graph is a PostgreSQL custom-format dump compressed with xz. The matching
+Tantivy search index is a zstd-compressed tar archive. A target-specific Rust
+query executable is the third artifact. The graph and index carry one build ID
+and graph schema version; mixing generations is rejected, and all three
+artifacts are SHA-256 verified.
+
+## Deliberate exclusions
+
+The snapshot contains no source archives, source bodies or snippets, comments,
+docstrings, README text, repository/package descriptions, copied license text,
+or local archive paths. Archive availability is false. Consequently,
+`source-search` and `fetch` are unavailable; use ordinary search for structural
+facts and obtain source separately under its repository's terms when needed.
+
+## Sources and licensing boundary
+
+The catalog combines generated dependency data from deps.dev's public BigQuery
+tables, PyPI package metadata, GitHub public-repository metadata, and structural
+facts extracted from public repositories. deps.dev documents its generated
+data under CC BY 4.0; that license does not relicense fields originating from
+PyPI, GitHub, or repositories. GitHub public visibility likewise does not place
+repository content in the public domain.
+
+The snapshot therefore does not claim one blanket copyright license over all
+identifiers or declarations. Its paths, names, kinds, and signatures are
+provided as structural/API facts under the applicable source terms and law.
+The signature allowance is a product risk decision, not legal advice or a
+conclusion for every jurisdiction. Users who retrieve source must comply with
+the corresponding repository license.

+
+## Verification and installation
+
+The release pipeline first runs `github_structure_audit.py` over the five-field
+JSONL stream, then `github_snapshot.py` rejects incomplete or non-structural
+builds, prose/archive leakage, mixed identities, and count mismatches before it
+writes `manifest.json`. Install with:
+
+```bash
+bnbcode research install --code --execute
+```
+
+The installer verifies both SHA-256 hashes, graph row counts, build/profile
+identity, and archive paths/symlinks before atomically placing the index and
+writing `~/.config/opencode/arxiv_graph.env` discovery settings.
+
+## Rebuilding from scratch
+
+The `builder/` directory holds the acquisition-time metadata inputs for
+recreating this corpus without BigQuery or the GitHub search API: the
+package/repository catalog, the PyPI dependency edges, and the PyPI package
+metadata export. These are public registry facts, not source content.
+`aggs/scripts/github_build_from_scratch.py` stages them, shallow-clones every
+catalogued public repository, extracts native dependency evidence, runs the
+closed-schema structural extractor and independent audit, and builds the same
+graph schema and structural profile as this snapshot. Because cloning observes
+current default-branch HEADs, a fresh build matches this snapshot's structure
+and pipeline but not necessarily its exact rows where repositories have moved
+or disappeared. Source is fetched directly from each repository under that
+repository's license.
+

+The `builder/` directory contains the repository catalog and PyPI dependency
+exports needed to rebuild this corpus from scratch by cloning the catalogued
+repositories. See `builder/manifest.json` for hashes and the dataset card
+body for the rebuild procedure.
