**Block override source tracking**: `Block_Override.source: Template` ensures warnings inside block overrides point at the override's source file (e.g., `page.html`), not the parent template (`base.html`).
### Lambdas
Spec-compliant. Stored as `any` values in the data context.
- **Interpolation lambdas**: `proc() -> string`, `proc() -> int`, `proc() -> bool` — called via `call_interp_lambda`, result stringified and escaped.
- **Section lambdas**: `proc(string) -> string`, `proc(string) -> int`, `proc(string) -> bool` — called via `call_section_lambda` with the raw section text (`node.content`). String result is re-parsed as mustache and rendered against the current context stack.
### Pipes
`{{key | op args…}}` for interpolation, `{{#key | op args…}}…{{/key}}` for sections. Stored as `[dynamic; MAX_PIPES]Pipe_Filter` on each `Node`. Applied in the renderer via `apply_pipeline` before truthiness/interpolation. Implemented filters:
