digital-history — Space Memory System

Memory is reconstruction, not retrieval.

149,515 messages across WhatsApp, Telegram, Claude, ChatGPT, Gmail — plus GitHub commits, articles, legal records. All searchable. All reconstructable. Fully offline once the server is up.

Prerequisites

Two things must be running:

# 1. Ollama (local LLM — run once, stays up)
ollama serve

# 2. Query server (D1 semantic search — run once per session)
dh server
# or: cd ~/Documents/digital-history && python3.13 -m uvicorn query_server:app --host 127.0.0.1 --port 8000

The query server loads ~250K vectors from D1 on startup (~60 sec first time), then stays in memory. HF_TOKEN is loaded automatically from ~/.secret_tokens.

Quick commands — use dh

dh reconstruct "what was happening with amrita late 2024"   # full pipeline: CARM + tone + Ollama
dh reconstruct -i                                           # interactive mode
dh chat "what kind of projects do I keep building?"         # fine-tuned Phi-3 + SQLite search
dh query "amrita conversations"                             # raw D1 semantic search
dh server                                                   # start query server on :8000

Or via bazinga --kb-d1

bazinga --kb-sources                                                         # check D1 reachable
bazinga --kb "your query" --kb-d1                                           # raw D1 search
bazinga --kb "your query" --kb-d1 --summarize --local                       # LLM summary
bazinga --kb "your query" --kb-d1 --summarize --voice --local               # reconstruction in your voice
bazinga --kb "your query" --kb-d1 --summarize --voice --memory-model        # fine-tuned Phi-3

Good queries

dh reconstruct "what was I building in early 2025"
dh reconstruct "what was happening with amrita late 2024"
dh reconstruct "ZK proofs consciousness substrate"
dh reconstruct "darmiyan lambda-g work"
dh reconstruct "what was I going through mid 2024"
dh reconstruct "phi crystal fractal dimension"

How it works (the pipeline)

Your query
    │
    ▼
query_server (localhost:8000)
    └── Roberts-16D cosine search over 496K embeddings in D1
    └── Returns top-15 real messages with dates and sources

Reconstructed memory in Space's voice

Data sources — what each command searches

Rule: for memory reconstruction, always use --kb-d1 or dh reconstruct. Never use plain bazinga --kb without --kb-d1 for personal memory queries — the ~/.bazinga index contains noisy local file scraps that are already in D1 at higher quality.

Lower-level interface — query.py directly

For raw search without bazinga (needs wrangler + Cloudflare auth):

cd ~/Documents/digital-history

python3 query.py "when did I talk about moving cities"
python3 query.py "amrita conversations about future" --k 30
python3 query.py "authentication bug" --source commit
python3 query.py "ZK proof ideas" --source message
python3 query.py -i    # interactive mode

What's in the database

DB size: 1.23 GB on Cloudflare D1 (paid tier, 10GB limit)

The fine-tuned model

• Base: Phi-3-mini-4k-instruct (Microsoft, 3.8B params)
• Adapter: QLoRA rank=16, 8.9M trainable params, 34MB on disk
• Trained on: 1,133 weekly windows — all messages, chronological, cross-source
• Training: ~7 hours on Apple MPS
• Use: bazinga --kb "..." --kb-d1 --summarize --voice --memory-model
• Note: loads the 7GB base model + 34MB adapter. Takes ~30 sec on first use.
