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.
