"""Add system_settings — runtime-editable, panel-tunable settings.
|
||
|
|
|
||
|
|
A key-value store for operator settings that must persist across restarts and be
|
||
|
|
editable from the panel. First user: ``transcript_retention_days``, the window
|
||
|
|
for the agent-transcript prune sweep. Seeded to 14 so the prune has a value
|
||
|
|
before anyone touches the panel; code defaults in ``roboco.config`` are the
|
||
|
|
fallback when a key is absent.
