1# Import chat history
2 
3Chat history is the most underrated source a person owns and the most sensitive.
4It records their reasoning, not just facts, and it also records things they would
5not want in a file that gets synced, committed and backed up.

7## Core rule
8 
9Privacy pass before triage, triage before ingestion. Never ingest an export
10wholesale.
11 
12## Workflow
13 
141. **Convert** with `scripts/chat_export_to_md.py` into one file per
15   conversation, filtering out short exchanges.
162. **Privacy pass.** List conversations touching health, money, other people's
17   private information, or confidential work. The user decides; you delete
18   nothing on your own.
193. **Triage the rest** into three piles: worth ingesting (they worked something
20   out, decided something, or got an explanation that landed), worth archiving
21   in `raw/`, and delete.
224. **Report the lists.** Move nothing yet.
235. **On approval, ingest** the first pile, with the instruction that these are
24   the user's own thinking: build pages around what they were working out and
25   what they concluded, not around the assistant's explanations.

29```
30Converted: <n> conversations (<n> skipped as too short)
31 
32Privacy review needed: <n>
33  <title> - <why>
34 
35Worth ingesting: <n>
36  <title> - <what it worked out>
37 
38Archive only: <n>
39Delete suggested: <n>
40```

42## Calibration
43 
44Expect roughly nine in ten conversations to be throwaway lookups. A triage that
45recommends ingesting most of the export has not filtered.
