coherence sweep wave 2 (mirror template): 'additive' aligned to site vocabulary in reader-facing lines; paper+DOI line added (findings 20,21)

Cross-repo audit findings 1-9,29: ESTATE snapshot to v0.15+DOI, suite
count 157, mermaid paper node, retired /paper/v0.x routes dropped from
the endpoint row, pasta row aligned to the subject repo's own claim
(field foundation proven, completion pending), llms.txt to v0.15+DOI,
paper/README supersession tail through v0.15, web.py route comment,
ltl.tex header comment no longer names the private reinvention outline
or the rejection (moat + zero-process in public files), litex-boards
dropped from the sources row (not in the pinned pool). Paper PDF bytes
untouched (comment-only tex change; v0.15 artifact stays byte-stable —
the committed PDF is the version-of-record built at v0.15 release).

 - Transparency log (RFC 9162): https://ltl.zkdefi.org — signed replay attestations of the Lean proofs. Nineteen leaves: three replay generations over four Ed25519 forks (newest at 44/44 certificates, leaves 13-16), the Lean mechanization of the log's own accumulator model (leaves 12 and 17), and the first post-quantum leaf - the SLH-DSA (FIPS 205) verify path (leaf 18); heads dual-signed (Ed25519 + SLH-DSA) since size 14. The mirror ships a fail-closed offline verifier (verify.py --all covers every leaf, signed head, and receipt) with an adversarial self-test.
