Module terragrunt 

Terragrunt-mimicking resolver.

Phase 6 lands the subset of Terragrunt that affects what HCL the component effectively sees: include, find_in_parent_folders, read_terragrunt_config, locals/inputs cascade, generate, dependency. Per 99-key-decisions.md D6, we mimic Terragrunt, never invoke its binary or shell out to git.

Per 14-terragrunt.md.

Public surface

• TerragruntResolver / FsTerragruntResolver: trait + default impl.
• TgContext: per-resolution context (workspace root, env-var policy, depth cap).
• TerragruntError: thiserror enum mirroring spec § 6.

Structs

FsTerragruntResolver

Default resolver — reads terragrunt.hcl files from the filesystem and threads them through the merge cascade.

TgContext

Read-only inputs to a single crate::terragrunt::TerragruntResolver::resolve call.

Enums

TerragruntError

Errors the Terragrunt resolver can surface.

Traits

TerragruntResolver

Trait every Terragrunt resolver implements. Phase 6 ships exactly one implementation: FsTerragruntResolver.
