Recomputes the SHA256 of the vendored ACP (Agent Client Protocol) schema
oracle files under priv/schema-oracle/v1/ and compares them against the
hashes recorded at pin time (see priv/schema-oracle/PINNED.md).
mix acp.schema.verifyThese files are a dev/test-only oracle (Apache-2.0, upstream
https://github.com/agentclientprotocol/agent-client-protocol, tag
schema-v1.19.0). They are excluded from the published Hex package via
mix.exs :files and exist purely so tests can validate our
hand-written/generated ACP types against the protocol's own JSON Schema.
The task therefore runs only in packages/raxol_agent_client_protocol of a
checkout of https://github.com/DROOdotFOO/raxol-agent. Anywhere else (this
package installed from Hex) it refuses with a message saying so.
Exits with a non-zero status (via Mix.raise/1) if either file is missing
or its hash no longer matches the pinned value -- which means either the
file was edited locally (don't -- re-run the pin procedure in
priv/schema-oracle/PINNED.md instead) or corrupted.
