Initial commit — memex

A compounding LLM-maintained knowledge wiki.

Synthesis of Andrej Karpathy's persistent-wiki gist and milla-jovovich's
mempalace, with an automation layer on top for conversation mining, URL
harvesting, human-in-the-loop staging, staleness decay, and hygiene.

Includes:
- 11 pipeline scripts (extract, summarize, index, harvest, stage,
  hygiene, maintain, sync, + shared library)
- Full docs: README, SETUP, ARCHITECTURE, DESIGN-RATIONALE, CUSTOMIZE
- Example CLAUDE.md files (wiki schema + global instructions) tuned for
  the three-collection qmd setup
- 171-test pytest suite (cross-platform, runs in ~1.3s)
- MIT licensed

"""Summarize extracted conversation transcripts via LLM.
Phase B of the conversation mining pipeline. Sends transcripts to a local
llama-server or Claude Code CLI for classification, summarization, and
key exchange selection.
Handles chunking and incremental summarization.
Usage:
python3 summarize-conversations.py # All unsummarized (local LLM)
python3 summarize-conversations.py --claude # Use claude -p (haiku/sonnet)
python3 summarize-conversations.py --claude --long 300 # Sonnet threshold: 300 msgs
python3 summarize-conversations.py --project mc # One project only
python3 summarize-conversations.py --file path.md # One file
python3 summarize-conversations.py --dry-run # Show what would be done
Claude mode uses Haiku for short conversations (<= threshold) and Sonnet
for longer ones. Threshold default: 200 messages.
