…entDiagnosticRecord Epoch E13 / WS-A. Lands the fail-closed L1 substrate contracts the rest of the epoch stands on (the RLD Rust workspace + Lean proof remain the reference impl): - LoaderFault: typed sum with stable codes (LDR-DEP-MISSING, LDR-ABI-MISMATCH, ...); no bare abort (I5/R2). Severity is a table of the failing edge's binding class (REQUIRED->fatal, FEATURE->degraded, WEAK->info, LAZY->handled|fatal), machine-checked. - ResilientDiagnosticRecord: root-cause-first; reproKey excludes timestamps/PIDs so identical defects coalesce; privacy-by-projection (I8) telemetry tier is an allowlist projection with symbolic (path-free) fields, validator-enforced. + canonical examples (the CoreSimulator abort re-encoded + its correct FEATURE-degraded form), invariant validator (make-wired), ADR-0018. Built in an isolated worktree.
…silientDiagnosticRecord contract-reconciliation CI requires the registry to be regenerated whenever a schema is added; this PR's schemas were missing from it.

A second conflict hunk (validate-multiverseal-twin-reference-impl vs validate-rld-examples target blocks) was left unresolved after the previous rebase, breaking make with 'missing separator'.

RLD loader/diagnostics contracts — LoaderFault + ResilientDiagnosticRecord
Epoch E13 / WS-A. Lands the fail-closed L1 substrate contracts the rest of the epoch (identity twin, capture receipts) stands on. The RLD Rust workspace + Lean launch-completeness proof remain the reference implementation; this is the wire/record form the fabric carries.
