Two changes that unwind earlier MazeNET-only assumptions and fix a
realism tell:
1. Persona resolution is now per-decky-source, not topology-only. The
scheduler walks the union view (list_running_deckies, including
fleet MACVLAN/IPVLAN + SWARM shards) and picks the right persona
list for each source:
* topology decky -> Topology.email_personas (per-topology richness
preserved)
* fleet / shard -> a single host-wide pool loaded from disk
(DECNET_EMAILGEN_PERSONAS, /etc/decnet/email_personas.json, or
~/.decnet/email_personas.json)
Operators install the global pool via 'decnet emailgen
import-personas <file>' which validates with the same Pydantic
schema the worker uses.
2. The driver now runs 'touch -d <Date>' inside the docker exec right
after the EML write so file mtime matches the email's RFC 2822
Date: header. Without this an attacker 'ls -lt'ing the spool sees
every email clustered inside the worker's tick window — the
cluster itself was a stylometric tell.
CLI now exposes 'decnet emailgen' as a sub-app with 'run' (default,
backwards-compatible with bare 'decnet emailgen') and 'import-personas'.
list_running_deckies carries topology_id through so consumers can resolve
the parent topology without a second round-trip.
Second orchestrator worker (decnet emailgen) that drips persona-driven,
threaded, multi-language fake emails into running mail deckies. Personas
live on Topology.email_personas; topology-wide language_default falls
through to any persona that doesn't pin its own. Em-dashes are
suppressed at the prompt layer by default and only lifted for personas
explicitly marked uses_llms_heavily — em-dashes are an LLM tell and a
flat corpus of em-dashed mail is a giveaway.
EML delivery writes into /var/spool/decnet-emails/<thread>/<msg>.eml on
the mail decky via docker exec; wiring the IMAP/POP3 templates to read
from that spool (replacing the hardcoded _BAIT_EMAILS) is the next step.
Adds decnet.fleet.reconciler — a pure async function plus a long-lived
worker — that periodically reconciles the three sources of truth on a
DECNET host:
1. decnet-state.json (CLI-canonical fleet record)
2. fleet_deckies table (DB mirror, written by engine.deployer)
3. docker inspect (actual per-container runtime state)
Drift handling:
* JSON has X, DB doesn't → INSERT (deploy ran with DB offline)
* DB has X (this host), JSON doesn't → DELETE (teardown ran with DB offline)
* Both have X, docker disagrees → flip state to running/failed/degraded
* Docker socket unreachable → leave existing state alone (don't
torch every row to torn_down)
Cross-host safety: deletions are scoped to host_uuid for the local host;
a master that runs both a local fleet and swarm workers will never
clobber a peer's slice.
CLI:
decnet reconcile --once # one-shot, prints counts
decnet reconcile [--interval N] # long-lived worker, mirrors
# orchestrator's lifecycle (control
# listener + heartbeat + tick loop)
Promotes decnet/fleet.py → decnet/fleet/ package so the reconciler can
live alongside it without name collision (build_deckies_from_ini and
all_service_names re-exported unchanged via __init__.py).
14 new tests cover state aggregation rules, all four drift directions,
host_uuid scoping, docker-unreachable safety, and worker shutdown via
the bus control event.
Adds a new decnet orchestrate worker whose job is to keep the honeypot
ecosystem from looking suspiciously static — a frozen LAN with no
inter-host traffic and no filesystem aging is its own honeypot tell.
MVP scope:
- New OrchestratorEvent table + repo methods (purpose-built sibling
to Log so synthetic events stay separable from attacker-driven ones).
- New orchestrator.{activity,file}.<decky_id> bus topics +
system.orchestrator.health heartbeat.
- SSH-only driver. Traffic action runs python3 inside src container
to TCP-connect dst:22 and read the SSH banner — real on-the-wire
SSH-protocol traffic without shipping creds. File action drops or
refreshes a small file via docker exec on the destination.
- Random scheduler (50/50 traffic/file when >=2 SSH-capable deckies
are running). Diurnal shaping, role-aware pairing, and session-aware
backoff are explicit non-goals for MVP.
- CLI registration, systemd unit (SupplementaryGroups=docker),
worker-registry entry so the dashboard shows orchestrator health.
- 11 tests: scheduler policy, driver argv shape + injection-safety,
end-to-end one-tick integration with FakeBus + SQLite.
The campaign clusterer worker mirrors the identity-side worker shell
(bus connect, heartbeat, control listener, slow-tick fallback) but
wakes on identity.> instead of attacker.> — campaign-level work is
gated on identity-layer changes, not raw observations.
The connected-components implementation reads identities via
list_identities_for_clustering, projects them with from_identity_row,
runs union-find over combined_campaign_weight, writes campaigns rows,
sets attacker_identities.campaign_id, and runs the same revocable-
merge pass as the identity layer (a merged-out campaign whose
identities no longer co-cluster with the winner gets revoked).
Bus: adds campaign.> family (formed / identity.assigned / merged /
unmerged) plus the cross-family identity.campaign.assigned so
existing identity-stream subscribers see the badge update without
having to subscribe to campaign.>. Wiki Service-Bus.md updated in
wiki-checkout in the same wave per the project's bus-signals
discipline.
CLI: decnet campaign-clusterer registered as master-only via
MASTER_ONLY_COMMANDS; --poll-interval / --daemon mirror the identity
clusterer command surface.
Adds the decnet clusterer master-only command + provider-subpackage
shape (base.py + factory.py + impl/connected_components.py) so
subsequent commits can land similarity-graph features without
churning callers.
The skeleton ConnectedComponentsClusterer.tick is a no-op; the
worker shell is fully wired (bus consumer on attacker.observed +
attacker.scored, slow-tick fallback, health heartbeat, control
listener, ClusterResult fan-out to identity.formed/observation.linked
/merged). Subscribers on identity.> see no events from this clusterer
until edge functions land, but the lifecycle is in place.
CLI command mirrors the reuse-correlate shape (--poll-interval, --ttl-hours,
--daemon). Run it under systemd as a sibling worker.
The API endpoint returns the most recent cached row for an attacker IP
or 404. Auth-gated via require_viewer like every other attacker route.
Also extends the worker test with a real FakeBus so the
attacker.intel.enriched publish path is exercised end-to-end (no longer
a no-op against NullBus).
The CLI was a day-one debug helper that read a log file or stdin and
printed a traversal table. It hadn't been wired to the live data path
since the engine moved into the profiler worker (DEBT.md:218). No
deploy unit, no caller, no doc relied on it. Removed the command and
its two tests; `decnet/correlation/` stays as a library consumed by
the profiler and the reuse correlator.
Adds CorrelationEngine.correlate_credential_reuse + the
`decnet reuse-correlate` long-running worker. The worker mirrors the
mutator's bus-wake + slow-tick pattern: wakes on credential.captured
and attacker.observed for sub-second latency, falls back to a 60s
poll if the bus is unavailable, and publishes
credential.reuse.detected once per new or grown CredentialReuse row
(group-deduped so a 5-cred reuse doesn't emit 5 partial events).
The web ingester now publishes credential.captured after every
successful Credential upsert; bus + new repo helper
find_credential_reuse_candidates feed the engine pass.
The hardcoded _DB_RESET_TABLES tuple had drifted — session_profile,
smtp_targets, and webhook_subscriptions were all missing, so
`decnet db-reset --i-know-what-im-doing drop-tables` silently left
them behind. Running it on a post-webhook install then letting
SQLModel.metadata.create_all() re-create tables produced a partial
schema: old rows survived, new columns didn't land, and endpoints
500'd on the missing columns (e.g. auto_disabled_at after the
circuit breaker merge).
Replace the hardcoded list with `SQLModel.metadata.sorted_tables`,
reversed for DROP safety (children first). Any future model addition
is auto-enrolled — no manual step, no more drift.
No behavior change on reset semantics; the SET FOREIGN_KEY_CHECKS=0
fence still covers any edge case the sort order misses.
Introduces the `decnet webhook` long-running worker that consumes the
internal bus and POSTs matching events to configured subscriptions.
Design: one task per (subscription, pattern) pair. Each task opens
its own bus subscription, iterates events, and dispatches via the
shared deliver() client. No intermediate queue, no in-memory filter
matching — the bus's own pattern matcher is the filter. Reloads on
`system.webhook.subscriptions_changed` signals from the CRUD router,
with a 60s fallback timer in case a signal is lost.
Shutdown propagates via CancelledError on the outer task; all inner
subscription tasks are cancelled and awaited in a finally block.
Bus unavailable → worker stays up in idle mode per the DEBT-031
pattern, logging one warning.
Registered as a master-only CLI command (agents don't configure
webhooks — the subscription store lives on master). systemd unit
mirrors the profiler template; added to decnet.target Wants= list so
`systemctl start decnet.target` brings it up alongside everything
else. `decnet init` auto-picks up the new .service.j2 via its
existing `glob("decnet-*.service.j2")` sweep.
polkit rule 50-decnet-workers.rules hardcoded isInGroup("decnet"),
so when 'decnet init --group anti' installed systemd units as
User=anti / Group=anti, the API (running as anti) could no longer
systemctl start/stop decnet-*.service — polkit fell back to
'interactive authentication required', which in a daemon context is
a hard fail:
START FAILED · COLLECTOR — Failed to start decnet-collector.service:
Access denied as the requested operation requires interactive
authentication.
Rename the rule to .j2, parameterise the group on {{ group }}, and
route _install_polkit through _render_template /
_write_rendered_if_changed. Now the polkit rule matches whatever
group was passed to 'decnet init'.
Test fixture updated to seed the .j2 variant.
Every plain `decnet deinit` ran userdel + groupdel unconditionally. In
dev the operator may pass `--user $USER --group $USER` to avoid file
ownership churn against a source checkout — at which point deinit
would cheerfully delete their own login account.
Move user/group removal behind --purge, matching the existing
behaviour for /var/lib/decnet + /var/log/decnet. Help text updated:
--purge now clearly advertises that it also wipes the service
user/group, with an explicit warning to only run it when `decnet init`
created the account in the first place.
Test updated: plain --deinit must NOT invoke userdel/groupdel;
--deinit --purge must.
Every decnet-*.service.j2 hardcoded User=decnet / Group=decnet. The
init CLI accepted --user / --group and used them for useradd,
chown, /etc/decnet ownership and ReadWritePaths — but the Jinja
context omitted them entirely, so
sudo decnet init --install-dir $PWD --user anti --group anti
rendered
User=decnet
Group=decnet
into every unit, which at best ran the workers as a user that didn't
match the files (fails to read the venv / config), and at worst spun
a parallel system user the operator never asked for.
Swap the hardcoded lines to {{ user }} / {{ group }} across all 13
templates and add both to the Jinja context in _install_units.
The systemd unit templates hardcoded {{ install_dir }}/venv/bin/decnet.
On production hosts enroll_bootstrap.sh creates exactly that path so it
worked. On dev boxes where the operator runs `sudo decnet init` against
a source checkout with a differently-named venv (.venv, .311, .312),
every decnet-*.service looped forever in auto-restart with:
Failed at step EXEC spawning .../venv/bin/decnet: No such file or
directory
Templates now use {{ venv_dir }} as an independent Jinja2 var. `decnet
init` adds --venv-dir (explicit override), otherwise autodetects:
1. $VIRTUAL_ENV (only when inside --install-dir, so a user-home venv
never gets baked into a root-owned unit),
2. {install_dir}/venv (production default; what enroll_bootstrap
creates),
3. {install_dir}/{.venv,.311,.312,.313} (common dev conventions).
Init aborts before any file writes if nothing resolves — an
operator-friendly error beats journalctl spam on every unit restart.
python3-venv doesn't set a persistent system variable — $VIRTUAL_ENV
lives in the activated shell only — so this has to be decided + baked
in at init time; there's no way for systemd to "inherit the current
venv" at unit start.
Test mode (--prefix) skips venv validation so the existing test suite
doesn't need to stub up a venv tree per case.
'decnet status' used to psutil-scan for cmdlines matching hand-coded
service launch args. That worked on dev boxes running workers via
'python -m decnet.cli ...' but missed the systemd reality on real
hosts: units may be installed but not started, failed, or in
auto-restart — all invisible to a cmdline grep.
New behaviour: status calls `systemctl list-units --type=service --all
--output=json 'decnet-*.service'` and renders the unit/load/active/
sub/description matrix. One view works for masters, agents, and
mixed hosts — iterates over whatever 'decnet-*' units were installed
by 'decnet init' / the enroll-bundle. Agent/master mode filtering is
no longer needed in the CLI; the host literally does not have
master-only units installed if it enrolled as an agent.
The psutil path survives as a fallback for boxes without systemd
(dev laptops, CI containers, minimal init systems) so the command
stays useful there. Clearly labelled 'psutil fallback' in the table
title so operators know which view they're looking at.
Populates Attacker.country_code + country_source (MVP) using the five
RIR delegated-stats files (ARIN/RIPE/APNIC/LACNIC/AFRINIC). Offline,
license-free, no outbound traffic that could burn honeypot stealth.
- decnet.geoip package with factory/base/lookup + rir/ subpackage
(fetch/parse/provider) mirroring the db + bus factory convention
- Profiler._build_record calls enrich_ip on every upsert
- Idempotent ALTER TABLE migrations for both SQLite and MySQL
- decnet geoip refresh/lookup CLI (master-only)
- /var/lib/decnet/geoip seeded by decnet init
- DECNET_GEOIP_ENABLED=false kill-switch; set in tests/conftest.py so
unit tests never trigger the first-access fetch
The config file `decnet init` dropped at /etc/decnet/config.ini was a
stub with a single [decnet] header saying 'reserved for future structured
settings.' Admins who wanted to tune DECNET_API_HOST, DECNET_DB_URL,
DECNET_BATCH_SIZE, etc. had to hunt env.py for the exact variable name
and drop it in .env.local.
Changes:
- decnet/config_ini.py — adds a _DOMAIN_MAP translation table covering
[api], [web], [database], [bus], [swarm], [logging], [ingester],
[tracing]. Loads regardless of mode; unknown keys inside a known
section log a WARNING (operator typos shouldn't be silent).
Explicit key map (not auto kebab-to-snake) so [web] admin-user lands
in DECNET_ADMIN_USER without silently renaming the env-var contract
consumers import from decnet.env.
- decnet/cli/init.py — renames the placeholder target config.ini →
decnet.ini (unifies with the name already used by load_ini_config and
the enroll bundle's _render_decnet_ini). Placeholder body now shows
every domain section as a commented example so admins learn the
shape by reading. Deinit removes both decnet.ini and the legacy
config.ini so upgrading hosts leave no orphan file.
Precedence is unchanged: real env > INI > built-in default in env.py.
os.environ.setdefault means systemd EnvironmentFile= and one-off
DECNET_FOO=bar decnet ... invocations always win.
Secrets explicitly NOT moved to the INI:
- DECNET_JWT_SECRET
- DECNET_ADMIN_PASSWORD
- DECNET_DB_PASSWORD
They stay in .env.local / EnvironmentFile= — never in a group-readable
INI, never in a diff, never on the dashboard.
Dev/profiling flags (DECNET_DEVELOPER, DECNET_EMBED_*, DECNET_PROFILE_*)
also stay env-only per maintainer direction — dev knobs shouldn't
be one 'I'll flip this for tonight' away.
Tests: +5 in test_config_ini.py (domain sections load regardless of mode,
env beats INI for domain keys, unknown key warns, absent section is
no-op, role section beats domain section via setdefault precedence). +1
in test_init.py (placeholder writes decnet.ini with every section
header present as commented guidance).
31 tests pass across the two files (was 26).
Distros reserve /opt for different things (some package managers own it
outright), and a DECNET install that wants to live at /srv/decnet or
/usr/local/decnet had to hand-edit 13 service files post-install.
Converts every deploy/decnet-*.service to a .j2 template keyed on
{{ install_dir }}, rendered by `decnet init` at install time. All other
paths (log_dir, state_dir, runtime_dir, user, group) stay standard —
only install_dir varies.
Changes:
- deploy/decnet-*.service → deploy/decnet-*.service.j2 (13 files).
- decnet init gains --install-dir (default /opt/decnet, preserves
existing behaviour byte-for-byte). Validates absolute-path at the
CLI boundary. Threads through useradd --home-dir and the dir-creation
list so the filesystem layout matches the rendered templates.
- _install_units renders via Jinja2 with StrictUndefined (typo → loud
error, not a silent broken unit). SHA over rendered output so
operators with a custom install_dir get idempotent re-runs.
- decnet.target, tmpfiles.d, polkit rule stay static — they don't
reference install paths.
- 4 new tests: custom install_dir renders into units, default remains
/opt/decnet, relative paths rejected, second run with same custom
dir is idempotent.
Reverse of init, step-by-step: systemctl disable --now decnet.target,
remove every decnet-*.service + decnet.target unit file, drop the
polkit rule, drop the tmpfiles.d entry, daemon-reload, remove
/etc/decnet + /etc/decnet/config.ini, /run/decnet, /opt/decnet, and
userdel/groupdel the decnet identity.
Preserves /var/lib/decnet and /var/log/decnet by default — those
hold operator data. Pass `--deinit --purge` to rm -rf them too.
Idempotent on a clean host (every step prints [SKIP]). Honours
--dry-run.
5 new tests cover the full-undo path, --purge, idempotent clean-host
deinit, dry-run side-effect-free behaviour, and the --purge without
--deinit guard.
Creates the decnet system user/group, installs every unit file from
deploy/ into /etc/systemd/system, drops the polkit rule, seeds
/opt/decnet + /var/{lib,log}/decnet + /etc/decnet + /run/decnet,
writes a placeholder /etc/decnet/config.ini, applies the new
tmpfiles.d entry so /run/decnet survives reboots, daemon-reloads,
and `systemctl enable --now decnet.target`.
Idempotent (re-runs print [SKIP] on already-configured items),
--dry-run previews the plan without touching anything, --no-start
defers the target start, --force overwrites even matching unit
files. Master-only (added to MASTER_ONLY_COMMANDS).
9 orchestration tests cover the non-root gate, dry-run, useradd/
groupadd argv, SKIP on present user/group, unit-file idempotency,
--force overwrite, --no-start suppression, happy path, and the
"deploy/ not found" error message.
apply_attach_decky requires an existing decky, so the MazeNET editor
had no way to grow a live topology: creating a new decky on active
topologies 409'd on the direct-CRUD createDecky call.
- Backend: new apply_add_decky that creates the decky row + its
home-LAN edge atomically, auto-allocating an IP if none pinned.
Post-apply validation still runs. Added to DISPATCH + _MUTATION_OPS
Literal + CLI help text.
- Tests: 3 new ops tests (happy path, duplicate-name rejection,
missing-LAN rejection) plus dispatch coverage update.
- Frontend: useTopologyEditor gains addDeckyToLan() composite. Pending
routes through createDecky + attachEdge as before; active routes
through a single add_decky enqueue. MazeNET.tsx drag-archetype,
duplicate, DMZ-gateway, and ctx-menu add-decky paths all use the
composite so active topologies stop 409'ing on new-decky drops.
Land the `decnet bus` worker and `get_bus()` factory. Transport is a
host-local UNIX-domain socket (0660, group=decnet); authz is the file
mode. Wire framing is a tiny verb-line + 4-byte-BE length + orjson body.
NATS-style wildcard topics (`*`, `>`). At-most-once, fire-and-forget —
DB stays the source of truth. `FakeBus` / `NullBus` for tests and the
disabled path. Cross-host federation is deferred to a future
`--bridge-tcp` mode; DEBT-030 is master-only and unblocked.
The web bundle proxy handled GET/POST/PUT/DELETE but not PATCH or
preflight OPTIONS, which broke browser calls to PATCH endpoints behind
the static-bundle server. CORS middleware had the same gap.
db reset drops-and-recreates a fixed table set in FK order. Topology
tables weren't in the list, so reset left orphan topology rows behind
and a fresh MazeNET deploy could collide with stale child records.
topology delete cascades children (LANs, deckies, edges, mutations) but
refuses while containers are still running — teardown is prerequisite.
show stopped assuming every decky carried a full decky_config blob;
MazeNET-generated deckies only get hydrated on deploy, so fall back to
top-level name/services when the config isn't there.
Legacy fleet deckies live in decnet-state.json; MazeNET topology
containers don't. Tag them at compose-time with
decnet.topology.service=true and let the collector match on that label.
Spin up the agent's log collector on the first successful /topology/apply
(not in the lifespan — that would break the no-docker-on-boot invariant)
and tear it down with the app. Land log lines in DECNET_AGENT_LOG_FILE,
separate from master-side DECNET_INGEST_LOG_FILE, so a dev box running
both roles can't forward its own ingest back to itself.
When master pushes a topology that differs from whatever is pinned
locally, teardown the predecessor and accept the new one. Refusing with
409 left the agent stranded after partial deploys. record_error now
persists the hydrated blob so a later teardown can still walk the LAN
list — otherwise a half-failed apply strands containers + bridges with
no breadcrumb back to them.
Adds the live-mutation pipeline for active/degraded topologies:
* TopologyMutation table with composite index (state, topology_id)
so the watch-loop guard query stays O(log n).
* claim_next_mutation is a single atomic UPDATE ... WHERE
state='pending' so racing reconcilers deterministically pick one
winner; losers see rowcount=0 and skip.
* reconcile_topologies drains pending rows per live topology, applies
via decnet.mutator.ops.dispatch, and on failure marks the mutation
failed + transitions topology to degraded.
* run_watch_loop gains a gated branch: flat-fleet mutate_all runs
every tick unchanged; the reconciler only enters when the cheap
has_pending_topology_mutation guard returns True.
* apply_* ops re-check hard invariants (names, IP collisions, subnet
overlap, known services, service_config shape) after every mutation
so the repo never lands in an invalid state.
* CLI: 'decnet topology mutate' / 'mutations' subcommands.
decnet topology {generate,list,show,deploy,teardown} wraps the new
persistence and deployer APIs. Structured text output, no ASCII art —
visual DAG rendering belongs in the web dashboard. Group is master-only
via MASTER_ONLY_GROUPS and a _require_master_mode guard on each body.
The 1,878-line cli.py held every Typer command plus process/HTTP helpers
and mode-gating logic. Split into one module per command using a
register(app) pattern so submodules never import app at module scope,
eliminating circular-import risk.
- utils.py: process helpers, _http_request, _kill_all_services, console, log
- gating.py: MASTER_ONLY_* sets, _require_master_mode, _gate_commands_by_mode
- deploy.py: deploy + _deploy_swarm (tightly coupled)
- lifecycle.py: status, teardown, redeploy
- workers.py: probe, collect, mutate, correlate
- inventory.py, swarm.py, db.py, and one file per remaining command
__init__.py calls register(app) on each module then runs the mode gate
last, and re-exports the private symbols tests patch against
(_db_reset_mysql_async, _kill_all_services, _require_master_mode, etc.).
Test patches retargeted to the submodule where each name now resolves.
Enroll-bundle tarball test updated to assert decnet/cli/__init__.py.
No behavioral change.
