Three producer-side regression guards. Each drives the worker's run
loop with a fake bus + stubbed repo and asserts the documented topic
fires when the producer has data:
- reuse correlator → credential.reuse.detected (one finding row)
- clusterer → identity.formed + identity.merged (one ClusterResult)
- intel worker → attacker.intel.enriched (one unenriched attacker
+ a fake provider returning a "malicious" verdict)
These complement commit 1's attacker.session.ended producer test —
together the four cover every TTP-relevant publisher in the tree
(modulo email.received, which has no producer yet; tracked in
DEBT.md).
Honeypot SSH containers run `PROMPT_COMMAND` that calls
`logger --rfc5424 --msgid command -t bash "CMD …"`. The Docker-stdout
reader prepends an outer RFC5424 envelope (HOSTNAME=<decky>,
APP-NAME=1, MSGID=NIL) around that inner syslog line. Both the
collector parser (`parse_rfc5424`) and the correlation parser
(`parse_line`) saw the outer NIL MSGID and emitted `event_type="-"`
for every shell command — which:
- kept `Attacker.commands` rows missing `command_text`
- left R0001–R0030 (the pattern rule pack that matches shell
commands) with no haystack
- made `decnet.collector.log` show `event written … type=-`
for the very lines that should be `type=command`
Both parsers now detect the inner-RFC5424 shape (`<TS> <HOST> <APP>
<PROCID> <MSGID> <rest>`) when the outer MSGID is NIL and the SD-arm
is also NIL, and re-extract HOSTNAME / APP-NAME / MSGID / remainder
from the body. The collector parser also recovers the post-SD msg
tail when the SD block isn't `relay@55555` (the bash CMD line carries
a `[timeQuality …]` block) so the kv-fallback can find `src_ip`.
Mirroring tests in tests/collector and tests/correlation pin both
the unwrap and the regression guard for non-double-wrapped lines.
SSH/telnet decky containers emit shell commands via `logger -t bash "CMD …"`
which produces RFC 5424 lines with MSGID=NIL. Both parsers were leaving
event_type="-", so the behavioral profiler's `_COMMAND_EVENT_TYPES` filter
silently dropped them — the IP profile existed but no command transcripts
or artifacts. Confirmed in the wild: 44/48 events from one attacker were
event_type="-".
Rewrite event_type to "command" in both parsers when MSGID=NIL and the
msg starts with "CMD ". Correlation parser also extracts the cmd= payload
into fields["command"] so the profiler can build the transcript; collector
parser leaves fields={} to avoid duplicate pills in the dashboard.
