📝 WalkthroughWalkthroughThe change adds CAdES inspection, certificate and timestamp validation, archive-timestamp freshness and renewal, and Trusted List qualification. It also reorganizes backend and timestamp modules, updates callers, and moves several test modules into sibling files. ChangesSeal evidence and module structure
Priority: ⬇️ Low Estimated code review effort: 4 (Complex) | ~60 minutes Change: Refactor Merge Risk: 🔵 Low · up to Reorganizing the seal crate leaves some API documentation misattached and some documentation links broken. Runtime behavior is unaffected, so the change is safe to merge once the documentation is tidied. 🚥 Pre-merge checks | ✅ 7✅ Passed checks (7 passed)

Repoint the intra-doc links in the split cades modules.
The split changed the resolution scope. super::trustlist now resolves under cades, which has no trustlist item. The other links should explicitly target the corresponding cades re-exports. The two links in signed.rs are in private documentation and matter when private items are documented.

Reattach the doc comments that the split placed on the wrong items.
The split kept the same number of /// lines but moved some of them to other items. Public and crate-internal functions now show docs that belong to something else:
crates/dpp-seal/src/cades/signature.rs#L195-L206: remove theverify_against_embedded_certificatesummary (Lines 195-202) from theRSA_ENCRYPTIONdoc block.crates/dpp-seal/src/cades/signature.rs#L270-L285: put that summary back at the top of theverify_against_embedded_certificatedocs, before the "# Every algorithm…" heading. Add "Whether a parsed structure's signature holds under its own certificate." as the doc ofsignature_holds.crates/dpp-seal/src/cades/timestamp.rs#L369-L370: delete the leftoversignature_holdsline, so the docs ofstamped_within_its_certificateopen with "Was the authority's certificate valid at the moment the token claims?".
