Subject: [PATCH] fix(hooks): pass --mode convos when mining a Claude Code
transcript dir
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The Stop and PreCompact hooks spawn `mempalace mine
` with no
`--mode` flag, which defaults to `projects` in cli.py. When MEMPAL_DIR
is unset, _get_mine_dir falls back to the parent of the transcript
JSONL — and miner.py's READABLE_EXTENSIONS includes `.jsonl`, so the
projects miner happily ingests Claude Code session JSONL as if it were
source code instead of conversation.
Make _get_mine_dir return (dir, mode): MEMPAL_DIR keeps `projects`,
the JSONL fallback yields `convos`. Both _maybe_auto_ingest and
_mine_sync now thread the mode into the spawned command.
