Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

Contract
- LineCounter initializes with empty line start offsets
- LineCounter addNewLine registers newline byte offsets in lineStarts
- LineCounter linePos resolves character offset into line and col numbers
- parseDocument with LineCounter populates line starts and locates AST node positions
- getNodePosition helper resolves line and column for AST node ranges using LineCounter
