# Implementation vs. Docs Status
One of the most important research findings is that upstream documentation status in `docs_status.yaml` is not the same thing as implementation depth. Some domains that look weak from the docs are actually well implemented in source, while others are genuinely thin.[^docs-status]
## Clear examples
### Docker / Container Manager
The upstream tracker marks Docker as `finished`, and the source header explicitly says it provides full coverage of all 12 `SYNO.Docker.*` namespaces, including container lifecycle, image management, network management, registry management, and compose project create/update/start/stop/delete/build flows.[^docs-status][^docker-source]
This means Docker should be treated as an implemented control domain, not as a direct-DSM gap.
### FileStation and Surveillance Station
Both are marked `partial` in the upstream tracker, but that label is about documentation state, not usefulness. FileStation is already a broad day-two operations surface, and Surveillance Station is a huge implementation area despite lagging docs.[^docs-status][^filestation][^surveillance]
### Virtualization / VMM
Virtualization is marked `not_started` in the docs tracker, yet the upstream source file exists and describes methods for managing tasks, networks, storage, hosts, virtual machines, and images.[^docs-status][^virtualization]
That makes it underdocumented, not absent.
## Why this matters
If the report over-indexes on docs warnings alone, it will understate some of the most useful control surfaces. The correct split is:
1. **Implemented and documented enough to trust from docs**
2. **Implemented but source-driven because docs lag**
3. **Actually thin or read-only in the wrapper**
The first two are both capability; only the third is a true wrapper limitation.
