Accumulating per-object validation errors and per-region syntax errors.
Rather than stopping at the first problem, a conformant processor accumulates errors and returns them together, alongside whatever data parsed successfully. This gives authors a full picture in one pass.
Each record is validated independently and may contribute zero, one, or many errors. A failing record is marked as an error; the others are unaffected:
~ $schema: { name: string, age: { int, max: 25 } }
---
~ James, 20 # ✓
~ Alex, 30 # ✗ invalid-range
~ Bob, 22 # ✓The result contains two valid records and one error entry — not a single fatal failure.
Syntax errors are accumulated per recovered region (between boundaries). One unparsable record yields one error, and parsing resumes at the next ~ or ---.
Because errors are accumulated rather than thrown, the loaded result includes the records that succeeded. Consumers can render valid data and surface the error list side by side (for example, editor markers at each error's position).
When two sections share a name, the duplicate is automatically renamed (users → users_2 → users_3), so the rest of the document still loads.
