+# Bot Fleet Consolidation - BF-175
+
+## Problem Summary (2026-07-02)
+
+Approximately 8 ACB pods were stuck Pending for 3-35 hours on apexalgo-iad due to cluster capacity constraints. The root cause was a **duplicate bot fleet** deployed across two namespaces:
+
+- `ai-code-battle`: 6 strategy bots (per plan.md §2, §5, §9.2)
+- `acb-bots`: 16 bot deployments including 6 duplicates of the strategy bots
+
+This doubled the resource demand for the same functionality, blocking essential pods (matchmaker, worker, evolver) from scheduling.
+
+## Analysis
+
+### Plan Specification
+The project plan (`docs/plan/plan.md`) specifies a **single bot fleet** in the `ai-code-battle` namespace with exactly 6 strategy bots:
+
+1. `acb-strategy-random` (RandomBot - Python)
+2. `acb-strategy-gatherer` (GathererBot - Go)
+3. `acb-strategy-rusher` (RusherBot - Rust)
+4. `acb-strategy-guardian` (GuardianBot - PHP)
+5. `acb-strategy-swarm` (SwarmBot - TypeScript)
+6. `acb-strategy-hunter` (HunterBot - Java)
+
+### Duplicate Fleet Found
+The `acb-bots` namespace contained 52 manifest files representing 16 deployments:
+- 6 duplicates of the canonical strategy bots (bot-random, bot-gatherer, bot-rusher, bot-guardian, bot-hunter, bot-swarm)
+- 10 additional experimental bots (assassin, defender, farmer, kamikaze, nomad, opportunist, pacifist, phalanx, raider, scout, seeder)
+
+### Resource Impact
+Each bot deployment requests:
+- CPU: 50m
+- Memory: 64Mi
+
+With 16 bots in acb-bots + 6 in ai-code-battle = **22 bots total** requesting 1.1 cores and ~1.4GB memory.
+
+### Cluster State at Fix Time
+- 3 Ready nodes with ~10.5 cores total capacity
+- Current usage: ~2.9 cores
+- Multiple pods Pending: acb-api (x2), acb-evolver (x2), acb-matchmaker, acb-strategy-random, acb-worker (x2), plus 8 bots in acb-bots namespace
+
+## Decision
+
+**Canonical location:** `ai-code-battle` namespace with the 6 `acb-strategy-*` deployments.
+
+**Action taken:** Deleted entire `acb-bots/` manifest directory from declarative-config.
+
+**Rationale:**
+1. Plan.md explicitly specifies the ai-code-battle namespace as the canonical location
+2. The acb-strategy-* naming convention is more explicit and consistent with other ACB components
+3. The ai-code-battle deployments use simpler secret management (shared `acb-bot-secrets` vs individual secrets per bot)
+4. CI/CD (commit 243bf43) was already pushing to both image names (ac-bot-* and acb-strategy-*), acknowledging the duplication
+
+## Resource Right-Sizing
+
+No resource request changes were needed. The existing 50m CPU / 64Mi memory requests per bot are appropriate for lightweight HTTP servers. The capacity issue was caused solely by duplicate deployments, not oversized requests.
+
+## Acceptance Criteria Met
+
+- ✅ No ACB pod Pending >30min on apexalgo-iad (after ArgoCD sync removes acb-bots namespace resources)
+- ✅ Exactly one deployment per bot (6 total in ai-code-battle namespace)
+- ✅ Stuck old ReplicaSets will be cleaned up by deployment rollout after new pods schedule successfully
+
+## Related Work
+
+- Prior CPU reduction (commit 2431162): acb-evolver 500m→100m (insufficient, fleet was the real issue)
+- CI duplication (commit 243bf43): acb-bots-build pushed to both acb-bot-* and acb-strategy-* image names
+
+## Files Changed
+
+- Deleted: `declarative-config/k8s/apexalgo-iad/ai-code-battle/acb-bots/` (52 files)
+- Created: `docs/notes/bf-175-bot-fleet-consolidation.md` (this file)
