The agent persona as a composable row. One config field, one prompt section.
The agent persona as a composable row. It can either shadow the deployment persona or own the complete system prompt.
[`dsh-system-prompt`](../../core/system-prompt/README.md) owns the deployment persona as its own config and registers that section unconditionally, so a process has exactly one. An [agent preset](../agent-presets/README.md) cannot mount the prompt registry itself — without a row of its own, a preset could change an agent's tools but never its identity. This package is that row.

`text` is a template, like any prompt section: complete `{{…}}` groups resolve strictly against registered prompt variables when the prompt renders, not when it assembles. Empty text still occupies the slot, so it shadows the deployment persona away entirely and then disappears at render.

Empty text still occupies the slot, so it shadows the deployment persona away entirely and then disappears at render. With `complete: true`, assembly still resolves contexts, tools, variables, and cooperative listeners, then the prompt registry restores this exact persona as the sole section; no identity, tool guidance, or listener can append prompt text.

#### What the model sees
The `deployment:persona` section at order 0, immediately after the harness identity opener, carrying exactly this row's configured `text` with prompt variables resolved. For an agent whose preset mounts this row, it replaces whatever persona the deployment configured.
The `deployment:persona` section at order 0, immediately after the harness identity opener, carrying exactly this row's configured `text` with prompt variables resolved. For an agent whose preset mounts this row, it replaces whatever persona the deployment configured. In complete mode, the model sees only this rendered section as its system prompt.
#### Token effect
Fixed for a given preset: the persona's own tokens on every request that agent makes, and none for any other agent. Empty text contributes nothing.
