The Bounty Vault page only read from the Bounty table, but
inotifywait-captured file drops (event_type=file_captured) and SMTP
quarantined messages (event_type=message_stored) were only landing in
the Logs table. AttackerDetail's tabs queried logs directly, so they
showed up per-attacker but were invisible on the global Vault page.
Mirror both events into Bounty as bounty_type=artifact with
payload.kind ∈ {file, mail} so the existing dedup
(bounty_type, attacker_ip, payload) collapses repeats by sha256. Add an
ARTIFACTS segment to the Vault filter row, plus dedicated render
branches: file drops show orig_path + size + writer attribution; mail
shows subject + From + attachment count + size, with the Mail icon
distinguishing them from FileText for file drops.
Forward-only — existing logs stay where they are. A backfill pass would
be straightforward (read Log WHERE event_type IN ('file_captured',
'message_stored') and feed each row through _extract_bounty) but is out
of scope here.
