Typora silence on edge keys and selection

Question

Where is Typora still thin as a direct source for Plate behavior decisions?

Current answer

Typora is strong on broad editing intent and many interaction surfaces, but it is still thinner on:

• some destructive edge-key behavior
• some reverse navigation cases
• structural multi-block selection law
• some atom-boundary details

Why this matters

These gaps are exactly where agents are tempted to over-lock the spec from vibes.

That should not happen.

Current rule

When Typora is thin here:

• use stronger adjacent evidence if it exists
• otherwise keep the area explicit as a Plate-owned decision
• do not pretend Typora settled it
