[dependencies]
# Floor requirement (not caret): the release pipeline stamps every workspace
# member to the release version at build time, so a caret req like "0.1.0"
# stops matching at the first minor bump (path deps must satisfy `version`
# too). ">=" keeps the stamped build resolving at any version and remains a
# valid crates.io requirement for the independent Context Graph Protocol publish (PUBLISHING.md).
#
# The floor moved to 2.0.0 with the open-`FrameKind` break (ADR 0011): this
# crate does not compile against `contextgraph-types` 1.x, so a floor of
# ">=1.0.0" would let cargo resolve a pair that cannot build.
#
# `attestation` is enabled unconditionally. It is off by default in
# `contextgraph-types` so that crate's "zero dependencies beyond serde" promise
# holds for a pure wire consumer; a host is the party that *checks* signatures,
# so it is the right place to pay for the cryptography (ADR 0016).

# Real content-addressing for the prompt-ingest provider (ADR 0006). The

# OS-boundary use stella-tools' bash tool makes.
