docs(bf-3gkv): verify plan section 5 already correctly documents 21 bots

- Section 5 already states 'Twenty-one built-in strategy bots'
- Bot table lists all 21 bots matching README.md
- Language distribution correctly counts 21 total (4+4+4+3+2+2+1+1)
- No updates needed - plan is already accurate

+# Bead bf-3gkv: Verification Complete
+
+## Task
+Update plan section 5: Strategy Bots count and bot list to reflect 21 bots instead of 6.
+
+## Finding
+The plan.md section 5 already correctly documents **21 bots** with accurate information:
+
+### Main Table (lines 727-749)
+- Lists all 21 bots with names, languages, strategies, and expected ranks
+- Matches exactly with README.md bot list
+
+### Language Distribution (5.1, lines 753-763)
+- Go (4): farmer, gatherer, opportunist, siege
+- Rust (4): assassin, phalanx, rusher, zone-driver
+- Python (4): economist, nomad, random, scout
+- Java (3): hunter, leader-targeter, raider
+- TypeScript (2): coordinator, swarm
+- JavaScript (2): kamikaze, pacifist
+- PHP (1): guardian
+- C# (1): defender
+
+### Verification
+- Section 5 header: "Twenty-one built-in strategy bots" ✓
+- Bot table: 21 entries ✓
+- Language distribution summary: 21 total (4+4+4+3+2+2+1+1) ✓
+- Matches README.md exactly ✓
+
+## Conclusion
+No updates needed. The plan.md section 5 already accurately reflects the 21 bots present in the bots/ directory and documented in README.md.
+
+## Possible Source of Confusion
+The bead description mentioned "SIX bots" but the plan.md already contains "TWENTY-ONE bots". This may have been:
+1. Based on an outdated version of the plan
+2. A reference to a different section
+3. A simple error in the bead description
+
+Current state is correct.
