ghostseal 1.0.0

Canonical cryptographic primitives for the GhostLogic stack (Tier 1).

ghostseal

Canonical cryptographic primitives for the GhostLogic stack — Tier 1.

This package is the single source of cryptographic truth that LEDGER_PROTOCOL.md anchors to. Every implementation that ingests into Blackbox (logicd, node-agent-watchdog, future agents in other runtimes) calls into ghostseal for canonical serialization, hashing, sealing, and signing. Byte-equality across language runtimes is the load-bearing guarantee (cross-impl item 106) — if two impls compute different canonical bytes for the same logical object, ghostseal is wrong, not the caller.

Specification

Authoritative contract lives at /home/contact/ghostlogic-spec/ghostseal-v1-spec.md. This package is the Python implementation of that spec; the Node parity package @ghostlogic/ghostseal is the sibling implementation.

Status

Phase 1 (the public surface from §3 plus a conformance corpus per §10) — in progress. See PROGRESS.md.

Non-goals

• ghostseal does NOT do HTTP. The legacy 0.1.0 SealClient is retained under ghostseal.legacy but new callers ship via their own HTTP path.
• ghostseal does NOT manage secrets at rest. Callers pass keys in; key storage (keyring, env, file) is the caller's concern.
• ghostseal does NOT define wire schemas beyond what sealing requires.
