v2.3.0

Added

• Added the feature-spike skill for bounded
  product-value and technical-feasibility experiments that end in a
  continue, change, stop, defer, or inconclusive decision.
• Added focused evidence guidance, a reusable feature-spike brief, five
  execution evals, and twenty balanced routing cases grounded in three
  completed proofs of concept and fresh no-skill baselines.

Documentation

  the expanded feature-delivery skill as released.
