Six new leaves (tree 13 -> 19, root 7ee23940…):
[13-16] dalek/anza/risc0/betrusted-ed25519-verified — re-attested at 44
certificates each (27 main + 4 apex + 13 scalar; the leaf 8-11
generation recorded 16). The delta is the P0-P2 hardening
campaign: scalar statements bound, kernel-side axiom gate,
driver surface with cones, declaration coverage both directions,
the accounting identity.
[17] ltl-accumulator-verified — 61 certificates; the log again carries
proofs of its own Merkle machinery, at the hardened state.
[18] fips205-slhdsa-verified — FIRST post-quantum leaf: 11 certificates
over the SLH-DSA-SHA2-128s verify path, apex
fips205.slh_verify_128s_accepts_iff.
Heads from tree 14 on carry a second, ADDITIVE signature:
SLH-DSA-SHA2-128s (FIPS 205), deterministic, over the same payload as the
Ed25519 signature. provider.slhdsa.pub ships beside the Ed25519 key.
Ed25519 remains the signature consumers must check; verify.py now judges
slh_dsa fail-closed where present (INVALID/WRONG-KEY/NO-PUBKEY fail; older
heads report ABSENT, allowed; pre-3.5 OpenSSL degrades loudly, never
silently). The ml_dsa slot stays not_configured — truthfully.
Honesty, unchanged by any of it: the certificates cover VERIFICATION paths
of the extracted Lean models; no signing operation is proven for any
algorithm; leaves are Ed25519-signed at issuance only.
Append-only law checked byte-for-byte before this commit: entries
000000-000012 identical, the six prior heads an exact prefix of the
history. verify.py --all: RESULT OK [full]. verify_selftest.py: GREEN (13
cases). Quorum gate: 5-way Ed25519 + 2-way SLH-DSA (incl. the verifier
built from the pinned proven source), all accept, all reject corruption.

The public face of the Lean Transparency Log: every leaf (including the
first run's honest audit-failure attestations), the full STH history
(witness channel), per-component receipts, the provider public key, and
a standalone stdlib-only verify.py.
