Package classify applies an ordered list of rules to a parsed stack and returns the set of matching categories.

Package config loads and validates the HCL policy file (.tfstackplan.hcl), resolving classification presets+rules into a single ordered rule list while preserving source declaration order.

Package differ turns a single attribute's before/after values into an ordered list of render variants (preferred → minimal).

Package fit deterministically reduces a model.Report so its rendered size fits a byte budget, degrading the largest attribute diffs first, then falling back through a report-level terminal cascade.

Package links resolves URL templates with {placeholder} substitution.

Package model holds the shared, budget-agnostic intermediate types that flow through the gather → fit → render pipeline.

Package plan parses a Terraform plan JSON document into a RawStack: reduced action counts plus the set of affected attributes for each change action.

Package plandir discovers per-stack Terraform plan JSON files under a single directory.

Package presets provides built-in named classification rule bundles that a repo can opt into without hand-writing regexes.

Package render turns a (possibly fit-reduced) model.Report into the final markdown document.

Package source indexes a stack's Terraform source so a plan resource can be linked to the file:line where it is declared.
