Public DEC-654 still requires a caller bearer; anonymous session now
returns that guidance as a tool error instead of silent valid:false.
Error text names JWT and API key, Grok bearer_token_file, and local
stdio. BearerFromRequest also accepts X-Api-Key / X-Verae-Key.
Document Grok stdio vs public URL; add scripts/sync-mcp-bearer.sh.
Start in-process nats-server on VERAE_NATS_LISTEN (default 127.0.0.1:4223;
empty disables). Queue-subscribe verae.ts.request|verify|hash.report with
ledger/veraetime routing and authctx.Resolve from authorization/access_token.
Publish verae.ts.completed on core NATS only (no JetStream). Wire embed into
main alongside Streamable HTTP; stdio MCP via go-sdk StdioTransport.
