SMTP template now writes each accepted DATA body as a .eml file into a
bind-mounted per-decky quarantine dir and emits a `message_stored` log
with sha256, size, decoded headers, and an attachment manifest
(filename + sha256 + size + content-type). Attachment hashing uses the
*decoded* payload so operators can match against VT / MalwareBazaar
directly. Body accumulator is capped at SMTP_MAX_BODY_BYTES (default
10 MB, matching the EHLO SIZE advert) so a streaming client can't OOM
the container.
The existing /api/v1/artifacts/{decky}/{stored_as} endpoint now takes
an optional ?service= query param (defaults to ssh for back-compat)
and can serve .eml files out of the smtp subdir. Forensic metadata
rides the normal log pipeline, same as SSH file_captured.
Adds the server-side wiring and frontend UI to surface files captured
by the SSH honeypot for a given attacker.
- New repository method get_attacker_artifacts (abstract + SQLModel
impl) that joins the attacker's IP to `file_captured` log rows.
- New route GET /attackers/{uuid}/artifacts.
- New router /artifacts/{decky}/{service}/{stored_as} that streams a
quarantined file back to an authenticated viewer.
- AttackerDetail grows an ArtifactDrawer panel with per-file metadata
(sha256, size, orig_path) and a download action.
- ssh service fragment now sets NODE_NAME=decky_name so logs and the
host-side artifacts bind-mount share the same decky identifier.
