The nested list-comp `[f"{id}-{svc}" for svc in [d.services for d ...]]`
iterated over a list of lists, so `svc` was the whole services list and
f-string stringified it -> `decky3-['sip']`. docker compose saw "no such
service" and the per-decky teardown failed 500.
Flatten: find the matching decky once, then iterate its services. Noop
early on unknown decky_id and on empty service lists. Regression test
asserts the emitted compose args have no '[' or quote characters.
systemd daemons run with WorkingDirectory=/ by default; docker compose
derives the project name from basename(cwd), which is empty at '/', and
aborts with 'project name must not be empty'. Pass -p decnet explicitly
so the project name is independent of cwd, and set WorkingDirectory=/opt/decnet
on the three DECNET units so compose artifacts (decnet-compose.yml,
build contexts) also land in the install dir.
- Fixed CLI tests by patching local imports at source (psutil, os, Path).
- Fixed Collector tests by globalizing docker.from_env mock.
- Stabilized SSE stream tests via AsyncMock and immediate generator termination to prevent hangs.
- Achieved >80% coverage on CLI (84%), Collector (97%), and DB Repository (100%).
- Implemented SMTP Relay service tests (100%).
