substrate Adding a fourth image to the two-machine scenario makes the bootstrap fail every time, with the store's readiness check producing no output at all — which says the container was not running rather than that the database was slow. Three images pass nine assertions; four never get past the store. More memory did not change it, so memory is not the cause; the change is kept because the reasoning holds on its own. Disk is the most likely explanation and nothing has measured it. It blocks proving the mesh runs its own artifact store, since the registry module needs a registry image to mirror. The module is written and accepted; what is unproven is a machine assigned it serving another.
04-ISSUES
The front door for "something is wrong" at the level of the mesh's design or governance. Diagnosis happens here, where the whole mesh is in view; the fix lands in the owning code repository.
What belongs here
| Belongs here | Belongs in the knowledge base |
|---|---|
| The design permits a failure to be silent | How to fix one occurrence of it |
| A documented rule is enforced by nothing | A command that works around it |
| A stated invariant is false in practice | A node-specific quirk |
| The owner is unknown and finding it needs the whole mesh in view | Symptom → fix, once the answer is known |
The knowledge base already holds the operational record and is indexed on symptoms. This folder is not a second copy of it. An issue here is a question HQ must answer; an entry there is an incident someone must clear. An issue whose answer is a general lesson belongs in both.

Rules
- Anyone may open an issue. No localisation is required to report one.
- The full flow is playbook
00-META/process/03-issues.md. - Closed issues are never deleted — they are the mesh's symptom-to-component memory.
wontfixis legitimate and requires a sentence saying why.
