The persistence catalog recognizes augmentations of '@deepseek-ai/dsh-session/types' alone, so the old root-specifier declaration compiled but silently vanished from the generated catalog; the Agent Note also drops its internal repository link for the public-links gate, and the persistence catalog pair re-records with the restored agent-preset section.

/**
|
|
* The session-log record of which preset a session actually runs.
|
|
*
|
|
* The creation header names the preset a session STARTED with, and it is
|
|
* deep-frozen because that is a creation fact. A session may still change
|
|
* preset while it is blank, and the effect of that change outlives the blank
|
|
* window: the first turn — and every turn after it — runs under the newly
|
|
* mounted composition. Recording the change is what keeps the log honest, and
|
|
* it is required outright by the repo's model-visible ⟺ logged rule, since the
|
|
* preset decides the tool schemas and prompt sections the model sees.
|
|
*
|
|
* Reconstruction reads {@link resolveSessionPreset}, never the header alone.
