Module template 

Shared Tera engine + context builders.

Two contexts:

• config_context — exposes only yui.* and the env(name=…) function. Used while parsing config*.toml (vars aren’t fully resolved yet).
• template_context — yui.* + vars.* + env(…). Used to render *.tera dotfiles after the merged config is known.

Functions

config_context

config_render_context

template_context plus self-referencing placeholders for the hook script vars (script_path / script_dir / script_name / script_stem / script_ext). Use this only for the config-load Tera pass, where those tokens haven’t been bound yet but should survive verbatim so the hook executor can resolve them at run time.

eval_truthy

Evaluate a Tera expression as a truthy/falsy boolean. Accepts either a bare expression (yui.os == 'linux') or a pre-wrapped one ({{ yui.os == 'linux' }}); used wherever the user writes a when condition (mount entry, render rule, marker link, file-header).
