User clarified: the earlier prune was a ONE-TIME cleanup of an over-backfill
bug, NOT a recurring retention cap. Saved history must persist. Removed
cmd_prune / --prune-older-than-hours entirely; the script now only captures
forward (default) or seeds a bounded window once. No code path deletes cube
entries. Verified: help has no prune arg, forward/seed dry-runs change no
state, live timer runs forward-only.
Captures user/assistant messages from /root/.hermes/state.db into the
'hermes' cube namespace as TYPE: HIST-QNA entries. Forward-only by default
(no backfill); --seed-hours N for bounded one-time population; idempotent;
--prune-older-than-hours to undo over-backfill. systemd timer runs every
5 min. Tested: 24h seed = 1171 msgs; prune cleared a 3164-entry backfill
to 44, then re-seeded correctly.
