Why This Is Hard

• Determinism is fragile: minor changes in ordering, hashing, or provenance break replay.
• Verification is expensive but necessary: soft checks invite drift and corruption.
• Shortcuts (e.g., skipping span+hash, loosening schemas) silently destroy auditability.
• Schema/version changes cascade: without migration, archives become unusable.
• Convenience features often undermine invariants; they are rejected by design.***
