State Management

State management is critical for SPAs and dynamic route transitions.

Page signature model

Each visited state is identified by:

• normalized URL
• compact DOM fingerprint
• semantic landmarks hash

This prevents revisiting equivalent states and controls infinite loops.

Frontier strategy

• Use queue-based traversal with depth tracking.
• Enqueue only same-origin and non-denied links.
• Preserve via_action metadata for diagnostics.

Edge history

Track transitions as:

(from_signature, action_type, to_signature)

This enables:

• loop diagnostics,
• dead-end detection,
• action redundancy filtering.
