Module loader 

HCL loader: read source files for a discovered component, parse them with hcl-edit, lower to our IR, and produce a RawComponent.

This module is the second cross-trust-boundary phase. Per 12-hcl-loader.md, the loader:

• takes file size / block-count / depth caps as input;
• never panics on adversarial bytes;
• emits per-file diagnostics, never aborts the workspace on a single bad file;
• drops the hcl_edit parse tree once lowering is complete (I-LOAD-2).

Structs

HclEditLoader

Default Loader implementation backed by hcl-edit::parser::parse_body.

LineCol

1-based (line, column) position in a source file.

LineIndex

Sorted prefix-sums of line-start byte offsets in a single source file.

LoadContext

Per-call context handed to Loader::load.

LoaderLimits

Per-file caps enforced by the loader.

ParseBytesResult

Output of HclEditLoader::parse_bytes. Cheap value type used by the fuzz harness and synthetic-input tests.

RawBlock

A lowered HCL block.

RawComponent

One discovered + parsed component, post-loader.

SourceMap

Cache of file contents and line indices, keyed by canonical path.

Traits

Loader

Loader trait. Phase 2 ships a single implementation, HclEditLoader; downstream may swap an in-memory variant for integration tests.
