Objective

Close the StructuredData milestone with cross-format conversion, limits, fuzzing seeds, and API/shim audit.

Deliverables

Run all OSD variants through every supported format and verify documented lossy/lossless boundaries.
Add corpus-driven no-panic tests for all translated malformed fixtures.
Audit recursion, length arithmetic, allocation, deterministic output, error context, and remaining generated shims.

Validation

All StructuredData tests pass.
Focused fuzz runs complete without panic or unbounded allocation.
Coverage reports zero unresolved StructuredData APIs and workspace gates stay green.

Prerequisite

Milestone 04 supplies implemented value types and the global API/test gates are complete.

Project constraints

Native Rust only; no LibreMetaverse/.NET bridge or fallback.
Keep mapped signatures fixed and preserve translated assertions exactly.
Enforce bounded parsing for untrusted input and update docs and parity status.

Implemented and verified in commit d980692. Added cross-format coverage for every OSD variant with documented lossy and lossless boundaries; checked-in malformed corpora and bounded deterministic mutations for Binary, Notation, XML, JSON, and Protobuf; deterministic map serialization checks; contextual error checks; and a native OSDParser declaration so StructuredData reports 16/16 native types and 295/295 native members with no generated shims. The hardening pass also found and fixed an XML truncated-scalar EOF loop. Verification: 35/35 native StructuredData tests pass, 78/78 pre-created StructuredData compatibility tests pass, controlled audit is 183 passed and 1203 expected standardized failures, API coverage/parity/generation checks pass, workspace check/API fixture/no-run/clippy -D warnings/docs all pass. Changes were reviewed against every issue deliverable after implementation.
