Subject: [PATCH] remove "How the Harness Reaches the World" slide from GDG
 event deck
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The slide titled "Tool Calling" / "How the Harness Reaches the World" was
added to the deck after the GDG Kolachi event on Apr 25, 2026, so it doesn't
belong in the historical record of what was actually presented. Reverting
the GDG deck to as-presented state.

The slide is preserved in the new claude-code-best-practice fork (which is
the canonical living reference owned by presentation-claude-code), so no
content is lost overall — this is a deliberate divergence between the two
decks.

Slide had no data-level, so the journey bar is structurally unaffected.
Renumbered slides 15..53 → 14..52 via sentinel-replacement. Final count: 52.
