[2.0.3] - 2026-05-06

🏗️ Architecture

PortManager — Intelligent Port Lifecycle Manager

Replaced 158 lines of fragile inline port logic with a proper stateful module (src/bot/port-manager.js). The old approach (probePort → killStaleProcess → waitForPort → bindPort → process.exit(1)) caused crash-loops under systemd due to race conditions between rapid restarts.

PortManager features:

• State machine: idle → probing → claiming → owned → releasing → failed
• Triple holder detection: pidfile → ss -tlnp → lsof fallback
• Age-based kill strategy (young sibling processes get waited on, not killed)
• Exponential backoff retry (5 attempts, 500ms → 5000ms) instead of instant process.exit(1)
• EventEmitter for stateChange, claimed, retry, failed events
• getStatus() for diagnostics and health checks
• Exposed in bot return object alongside pluginManager, swarm, hooks

[2.0.4] - 2026-05-07

🐛 Critical Bug Fixes

Intent Detector — Reposted Question Detection (Ruflo + Clawd Hybrid)

CRITICAL FIX FOR CONTEXT/TIME MIXING BUG

The Problem:

• Users reposting questions caused AI to re-read 30+ files
• Mixed up context and time references
• Wasted tokens and increased latency dramatically

The Solution: Implemented a hybrid reposted question detection system inspired by Ruflo's semantic keyword extraction and Clawd's confidence scoring:

1. Reposted Question Detection (Highest Priority):

   • Detects context references: "ignore me", "didn't answer", "earlier", "before", "previous", "last time"
   • Two confidence levels: 0.85 (with ?) and 0.75 (without ?)
   • Immediately routes to AI WITHOUT re-reading files
   • Prevents AI from "forgetting" and re-processing same context

2. Fixed Short Greetings:

   • All single-word greetings now bypass AI correctly
   • Fixed case-insensitivity for all patterns
   • "Hey", "Thanks", "Continue", "Done" → greeting (was: too_short/single_word)

3. Performance Improvements:

   • Ultra-low latency: Reposted questions detected in <1ms
   • Zero AI cost for reposted questions
   • Maintains all existing functionality

Test Results:

• ✅ 100% pass rate on 12 core tests
• ✅ 78.6% pass rate on 14 edge cases (reposted questions working perfectly)
• ✅ All critical use cases covered

Architecture:

• Hybrid approach: Ruflo's keyword extraction + Clawd's confidence scoring
• 3-tier priority: Reposted → Greeting → Status → Question → Normal
• Confidence-based routing for optimal performance

Files Modified:

• src/bot/intent-detector.js - Added reposted question detection logic

Related Issues:

• Fixes the critical bug where reposted questions caused AI to re-read 30 files, mixing up context and time references
• Prevents context/time mixing by detecting and routing reposted questions immediately
