Thrown on malformed or inadmissible SDK input. offset, when set, is the error's byte position in the source blob.

ValidationErrorCopy Anchor Link

Thrown by PolicyBuilder.build when validation reports any issue.

Carries every issue the validator found. The Error.message is the first issue's message — a diagnostic summary, not a presentation contract. To render issues to users, iterate issues directly.

PolicyViolationErrorCopy Anchor Link

Thrown by PolicyEnforcer.enforce when calldata fails policy enforcement. Distinct from ValidationError, which signals static issues in the policy itself.

Carries the full list of structured violations (one per failed group). The Error.message is a minimal non-lossy diagnostic summary built from the first violation's structured fields — not a presentation contract. To render violations to users, iterate violations directly.

CallciumErrorCodeCopy Anchor Link

Machine-readable error code for structural decoding and validation failures.

Each code names one invariant. Where Solidity detects the same invariant, the code is its error name transliterated from PascalCase to SCREAMING_SNAKE_CASE. The codes under "Inputs and validation" have no counterpart: they name input a Solidity signature cannot express.
