Subject: [PATCH] Update agent documentation to reflect completed SNMP and
 hierarchical assignment work

- Mark SNMP client as fully implemented
- Update status to show hierarchical agent assignment complete
- Reorganize critical path to prioritize integration testing
- Update success criteria and estimated timeline
- Remove outdated SNMP integration sections

 ## Critical Path to Production
 
-### 1. Complete SNMP Integration (Priority: HIGH)
+### 1. Integration Testing (Priority: HIGH) ⬅️ **START HERE**
 
-**Problem**: The Rust `snmp` crate v0.2 API differs from the initially designed implementation. Current code compiles but returns errors for actual SNMP operations.
-
-**Options**:
-
-#### Option A: Complete `snmp` crate integration (Recommended)
-**Effort**: 4-8 hours
-**File**: `towerops-agent/src/snmp/client.rs`
-
-Research the correct `snmp` crate 0.2 API:
-```bash
-# In towerops-agent/
-cargo doc --open --package snmp
-```
-
-Key methods to implement:
-- `SyncSession::new()` - Create session
-- `session.get()` or similar - Perform GET
-- `session.getnext()` or similar - Perform GETNEXT (for WALK)
-- Error handling for timeouts, auth failures
-
-**Reference**: Check `snmp` crate examples and tests
-
-#### Option B: Use alternative SNMP library
-**Effort**: 6-12 hours
-
-Alternatives:
-- `snmp-mp` - More actively maintained
-- `snmp-parser` - Lower level, more control
-- `rasn-snmp` - ASN.1 based
-
-Replace in `Cargo.toml` and reimplement `client.rs`.
-
-#### Option C: Implement basic SNMP manually
-**Effort**: 16-24 hours
-
-Implement SNMPv1/v2c protocol directly:
-- ASN.1 BER encoding/decoding
-- UDP socket communication
-- PDU construction
-
-**Not recommended** - reinventing the wheel.
