Struct Migrator 

pub struct Migrator { /* private fields */ }

The migrator. Stateless by design — run is a pure fn of input.

Use Migrator::default for the standard transform table. Custom consumers can construct with Migrator::new(&[...]) to add / omit rules for their yaml corpus (currently unused; opened for future extension without wire-format changes).

Implementations

impl Migrator

pub fn migrate( &self, yaml: &str, ) -> Result<(String, MigrateReport), MigrateError>

Comment-preserving line-based codemod. Copyright headers, audit trails, and # Reason: blocks survive the migrate round-trip byte-identical.

Strategy:

• Iterate input line by line
• Preserve comment / blank / doc-header lines verbatim
• Detect step lines (^\s*-\s+<verb>[:.]?) and rewrite the verb portion using smix_verbs::VERB_TABLE
• Argument transforms (e.g. timeout → timeoutMs, max → maxRetries) run against the arg mapping only when the arg is inline on the same step line — for multi-line mappings we scan following-indented lines

The prior serde_norway::Value roundtrip is retained as a fallback for edge cases: when the line-based rewriter can’t confidently identify a step (deeply nested / complex flow- style), fall back to the AST path for that yaml doc.
