#1230 fixed --mode convos for the case where MEMPAL_DIR was unset, but
left two configurations broken:
- MEMPAL_DIR set to a project dir: convos never mined (MEMPAL_DIR
overrode the transcript path); only project files were ingested.
- MEMPAL_DIR set to a conversations dir per the old hooks/README: the
projects miner ran on JSONL — same wrong-miner behaviour.
The shell hooks (mempal_save_hook.sh, mempal_precompact_hook.sh) had
the same MEMPAL_DIR-overrides-transcript bug AND were missing --mode
on every spawned `mempalace mine` call.
Make the auto-ingest *additive*. _get_mine_dir → _get_mine_targets,
returning a list of (dir, mode) pairs:
- MEMPAL_DIR (when valid) contributes (dir, "projects")
- A valid transcript JSONL contributes (parent, "convos")
- Both can appear together; the hook spawns one ingest per target
Same change applied to the shell save and precompact hooks. Precompact
also gained transcript_path parsing so it can run the convos mine
synchronously before context is compressed. hooks/README.md updated to
describe MEMPAL_DIR as a project-files target, never a convos target.
TDD: test written first, failed, then fixed.
Problem: save hook says "saved in background" but MEMPAL_DIR defaults
to empty, so nothing actually mines. Users get no auto-save despite
the hook firing every 15 messages.
Fix: use TRANSCRIPT_PATH (received from Claude Code in the hook's
JSON input) to discover the session directory. Mine that directory
automatically. MEMPAL_DIR is still supported as override but no
longer required.
Also fixed: bare python3 → $(command -v python3) for nohup safety.
