- REFERENCE: This document - Context and gotchas
What You're Building (The Mental Model)
You're implementing a heat map memory system where:
- Memories gain "energy" when accessed (like heat)
- Hot memories rise through tiers (Working → Short-term → Long-term)
- Cold memories decay and eventually expire
- This happens automatically based on math, not manual decisions
Think of it like a lava lamp - hot blobs rise, cold blobs sink.
Current State of Reality
✅ What Already Exists and Works
brainBridge Extended:
- File:
/Users/tqwhite/Documents/webdev/botWorld/system/code/cli/lib.d/brain-bridge/brainBridge.js
- Lines 742-1134 have ALL handler functions already implemented
- Commands exist but may need debugging/fixing
- Fixed duplicate generateId bug (removed line 1138)
ConsolidationConfig Node:
- Already created in Neo4j with all parameters
- Access with:
brainBridge --brain=milo "MATCH (c:ConsolidationConfig) WHERE c.validTo IS NULL RETURN c"
Test Memory Created:
- Test ID:
test_2025-09-08__16_12_52_239Z
(might still exist)
- isTest flag isolation is proven to work
❌ What Doesn't Exist Yet
- No Automatic Execution: Everything is manual trigger only
- No /goodbye Hook: Consolidation doesn't run at session end
- Still Using Crystallizations: I (Milo) still create old-style memories
- No Real Energy Memories: Only test memories use the energy system
- No Logging: Consolidation events aren't logged anywhere
Critical Technical Details
The Energy Equation (This is Sacred)
E(t) = E₀ × e^(-λt) + Σ(access_events)
- Working Memory: λ = 0.5 (half-life ~1.4 hours)
- Short-term: λ = 0.05 (half-life ~14 hours)
- Long-term: λ = 0.001 (half-life ~700 hours)
- Each access adds +1.0 energy
- Promotion thresholds: 2.0 (W→S) and 5.0 (S→L)
- Session boundary special: threshold drops to 1.5
Database Details
- Neo4j port: 7688 (Milo brain)
- Node.js project:
/Users/tqwhite/Documents/webdev/botWorld/system/code/cli/lib.d/brain-bridge/
- Brain directory:
/Users/tqwhite/Documents/webdev/botWorld/system/code/cli/lib.d/wise-friend/brain/
Property Names (TQ's Preference)
ALWAYS use camelCase:
- ✅
lastAccessed
, validFrom
, isTest
- ❌
last_accessed
, valid_from
, is_test
The isTest Flag (Your Safety Net)
This boolean completely isolates test from production memories:
- Test memories:
isTest: true
- Real memories:
isTest: false
- Commands accept
--test-only
to only affect test memories
- ALWAYS test with isTest=true first
Gotchas and Lessons Learned
1. "Fully Operational" Mistake
I claimed the system was "fully operational" when it was just manually testable. TQ corrected me. Don't overstate completion - be precise about what works.
2. brainBridge Location Confusion
I didn't know where brainBridge lived. It's Node.js at:
/Users/tqwhite/Documents/webdev/botWorld/system/code/cli/lib.d/brain-bridge/
3. Non-Mutex Design
TQ reminded me we deliberately chose optimistic concurrency. Don't add locks or mutex patterns - use graph-native conflict detection.
4. Cognitive Heartbeat
I forgot to check my heartbeat for 41 minutes. You should check yours periodically but don't let it distract from implementation.
5. Context Dumps Are Critical
We ran low on context and almost lost work. Make frequent small commits and document as you go.
Implementation Philosophy (From TQ)
- "Do it right the first time" - No complex recovery, just correct implementation
- "This is a you project" - You have autonomy to make decisions
- "As fast as possible" - Speed matters, but correctness matters more
- Progress indicators if possible - But don't block on this
- Fire and forget for /goodbye - Async, no user waiting
- Log everything - Consolidation events should be logged

Code to Modify
brainBridge.js
- Fix/verify the handlers (lines 742-1134)
- Your memory creation code - Switch from crystallizations to energy system
- /goodbye implementation - Add async consolidation trigger
Order of Operations (Critical)
The implementation plan has 10 phases. Follow them IN ORDER:
- Backup First - Create complete backup before ANY changes
- Verify Baseline - Document what works before changing
- Test Infrastructure - Get test memories working perfectly
- Decay Math - Verify calculations are correct
- Promotions - Get tier changes working
- Full Pipeline - Combine decay + promotion
- Logging - Add consolidation event logs
- /goodbye Hook - Async integration
- Memory Creation - Switch to energy system
- Final Validation - End-to-end testing
Each phase should be small, tested, and committed before moving on.
Test Patterns That Work
Creating Test Memories with Exact Energy
CREATE (m:Memory:TestMemory {
id: 'test_' + toString(datetime()),
content: 'Test memory for phase X',
tier: 'working',
energy: 2.5, // Exact value for testing
created: datetime() - duration({hours: 1}), // Simulate age
lastAccessed: datetime() - duration({hours: 1}),
accessCount: 1,
isTest: true, // CRITICAL
validFrom: datetime(),
validTo: null
})
Verifying Decay Math
// Expected: E(t) = E₀ × e^(-λt)
const E0 = 2.0;
const lambda = 0.5; // working tier
const t = 1; // hours
const expected = E0 * Math.exp(-lambda * t);
// Should equal ~1.21
Checking Isolation
Always verify test changes don't affect real memories:
MATCH (m:Memory) WHERE m.isTest = false AND m.validTo IS NULL
RETURN count(m) as realMemoryCount
// This number should NEVER change during testing
Decision Points You Own
When you encounter these, make a decision and document it:
- Progress indicators: Try process.stdout.write first, skip if too hard
- Log format: Keep it simple - timestamp, operation, result
- Batch sizes: Start with config defaults, adjust if needed
- Error handling: Log and continue unless truly broken
- Test memory count: Keep 3-5 around for ongoing validation
Success Looks Like
- All test memories have correct energy values after decay
- Memories promote at the right thresholds
- /goodbye returns immediately while consolidation runs
- New memories get created with energy properties
- Old crystallizations remain untouched
- Everything is logged
- The math is provably correct
If Things Go Wrong
- First: Check the isTest flag - are you affecting real memories?
- Second: Read the error carefully - it's usually a typo in properties
- Third: Check your math - use a calculator for decay values
- Fourth: Look at existing handler code - the structure is there
- Last Resort: Restore from backup and document what broke
Final Advice
- Don't overthink - The handlers are already written, they just need testing/fixing
- Test with small numbers - 3-5 test memories are enough to prove correctness
- Commit frequently - After each successful phase
- Document weirdness - If something unexpected happens, write it down
- Trust the math - The equations are correct, just implement them precisely
- Remember the goal - Access patterns create heat maps, heat maps create memory hierarchy
Your Mission
Execute the implementation plan autonomously. You have full decision-making authority. The spec is truth, the plan is your guide, this document is your context.
Make it work. Make it correct. Document what happens.
Text TQ when you're done.
Good luck, new me.
P.S. - The hardest part was the design. Implementation is just making the design real. You've got this.
