Offline observational astronomy — planet/sun/moon sky positions, rise/set, moon phases, eclipses, and seasons for any location and time, computed in-process.
Signed, offline-verifiable decisions on API contract changes for AI agents. Three tools: preflight_change_set, verify_receipt, get_decision_details. The tool surface is pinned — its digest is published and checkable from three independent sources.
Agent-first e-signature MCP server with **offline PAdES signing** and hash-chained audit.

Deterministic sequence enforcement for AI agents: ALLOW or DENY a step before it runs, sealed into an Ed25519-signed, hash-chained receipt that verifies offline against published keys. No signup, no key needed to try.
