Watchtower Agent

Canonical ID: /learning-castle/0217 · Implements: /learning-castle/0114 Watchtower Schema · Role: bounded change observation.

The Watchtower Agent observes how the live estate changes after the Castle baseline. It compares expected and observed owners, routes, statuses, Archives and control documents, then signals drift. It does not enforce a block, declare a new owner or edit the site by itself.

Drift Signal

signal:
  observation_time
  baseline
  observed_change
  affected_node_or_route
  expected_state
  observed_state
  confidence
  likely_severity
  suggested_receiver

severity:
  INFO = change_without_integrity_risk
  WATCH = incomplete_or_ambiguous_change
  WARNING = likely_route_owner_or_return_drift
  CRITICAL = active_boundary_or_kernel_conflict

Receiver Rule

• Potential missing connection → Scout Agent.
• Active route integrity risk → Sentry Agent.
• Index or orphan drift → Archivist.
• Owner conflict → Castellan plus Validation.
• Protected-boundary concern → Portcullis Guard.
• Live-site correction → human authority after validated proposal.

The Watchtower should preserve change history so that a new edit does not erase what the previous verified state was.

The Watchtower notices that the map and the world have begun to differ.
