Crate gmeow_gts 

GTS (Graph Transport Substrate) format engine — docs/GTS-SPEC.md Draft v0.3.

A GTS file is a CBOR Sequence of one or more segments (#3.1), each an append-only log: a Header followed by frames chained by BLAKE3 content-id ("id"/"prev", §6/§9.1). reader::read verifies the chain and folds the log into a model::Graph (§7.5), degrading undecodable frames to opaque nodes (§7.6) instead of aborting — the reader is total.

This crate is the Rust counterpart of the Python reference oracle (src/gmeow_tools/gts/); both are gated against the same frozen language-neutral conformance corpus in vectors/ (§18). The Python side keeps the producer; this crate owns the format engine.

Modules

codec

The GTS transform catalog (§8) — mirror of src/gmeow_tools/gts/codec.py.

compact

Streamable compaction (GTS-SPEC §10.1): re-author the ordering, only the ordering — mirror of packages/gts/src/gts/compact.py.

db

Relational exports for the folded graph (§14).

dumpdir

Directory dump export for human and tool inspection.

model

In-memory data model for the folded graph — mirror of src/gmeow_tools/gts/model.py.

nested

Bounded nested-GTS discovery for Full Reader callers.

nquads

The gts → nquads transform (§14) — mirror of src/gmeow_tools/gts/nquads.py.

openpgp

Minimal OpenPGP reader for Ed25519 armored public/secret keys (§9.2).

policy

Trust and profile-policy checks layered above core GTS validity.

writer

A GTS writer: build frames, maintain the id/prev chain, emit a CBOR Sequence.
