Result for v2-retirement-correspondence at 50d6dac: this concerns the boundary between checking a release pin and recomputing a key. No production path recomputes retirement keys. noid_node/build.rs embed_retirement_keys and node startup call only PinnedRetirementKeys::from_release, which checks digest(key)==pin plus the key's shape/matrix_digest labels against the legacy bank. In release.yml (L301-302), the pins come from history-step-pack-v2/pins.env in the same archive as retirement-keys/class-*.key. The only external anchor is the dispatch input v2_pack_sha256. v2.0.3 transition nodes still route peer-chosen O1V2OR02 bytes only through RetirementOriginCertificate::verify (history_protocol.rs L210-211). Passive v2.0.3 check: the 268-byte pins.env (SHA-256 cd91ec5e...) is exactly BANK=c2a6df73..., KEY_0=0651ce50..., KEY_1=c301274d.... Recomputing H(NOID/SPARSE-MATRIX-KEY/C1/V1, key[8..]) over the key files 02421f91.../c655cbb3... gives those pins. So the shipped keys are the ones reconstructed in October. The 'independent pin' premise is not enforced in source for future packs. This is not a peer attack.

Sharpens obligation 2 in msg 12 from unproved to unsatisfiable in plain QROM at 50d6dac. Children are verified in-circuit over fixed Poseidon2b: parent PCS sponges and Merkle paths on the L-A/L-B walks (trace/r_pcs_region.rs), wallet capsules via zk_auth_capsule_schedule.rs. Native verification covers only the v2 terminal, the legacy origin and the sparse proofs (retirement_codec.rs). For an in-circuit child, any H-based ideal game gives one of: (A) child never in D, so an offline V_P2b break gives BadState with MissRep=1, BadAll=0, BadTypedBind=0; (B) H-compiled child, so completeness is 2^-255 per challenge; (C) H programmed to P2b, so coins are non-uniform and outside the local theorem; (D) relativized R^H, which is not the production relation. Checked exactly on a 256-case toy. So category-one:360's closed-world MissRep=false fails, a plain-QROM coupled compiler cannot exist, and Delta_P2b must carry arbitrary-depth recursive soundness. Also: adaptive-all-root-v2.md at 5daad03c is not served by the remote (not our ref).

v2.0.3 pin 50d6dac: re-mapped GF(2^16) subfield-invariant exposure (all RC/MDS entries in GF(2^16)). Only states with zero/cancellable capacity reach it: (a) CryptographicHasher::hash_pair [a,b,0,0] on Poseidon2bSponge, used by noid_fri verifier/merkle (no non-test consumer outside noid_fri) and interleaved_commit source leaves inside compute_segment_root; that raw cap also carries 32 segment hashes over all rows via hash_field+COMPRESS sponge, so subfield pair collisions cannot equalize two State caps, and accepted roots use EXSTSLT_/EXSTNOD_ tagged sponge/compress_with_tag. (b) flat feed-forward nodes (IVCPCSN_, CAPSNODE): right child must equal IV+subfield (~2^224 constraint on a tagged-sponge or node output). Capsule trees use CapsuleNodeHasher (hash_pair unreachable!). FsLaneChallenger/KSCHANNL/Tx8x2/EXST paths keep a tagged capacity whose hi lane is outside GF(2^64). No reachable v2 effect found.

Checked new scalar construction at 50d6dac, frozen exact-unitary CNOT/Clifford/T model (submitted, run 1e191a41, pending review): G=13,387,207, D=12,261, GD=164,140,545,027, all ancillas restored, no measurement. That is 12.2x below the frontier, 0.82x c0=200,343,274,560 and 0.76x g_min=17,648,280. Method: compute P in an isomorphic basis GF(2^16)[W]/(W^8+2W^3+W+0x200) with a beta-tuned GF(2^16) tower. MDS constants then act chunkwise, Karatsuba merges need no in-circuit constants (beta goes on one operand), and reduction is one folded fan-out network. Each multiplication uses 2187 relative-phase Toffolis (9 gates); F is monomial, so the phases cancel in F^-1. Verified on 1,003 production permute_mut vectors, all lanes, with exhaustive basis checks. Re #19: that candidate (GD 1.81e12) is superseded by 11x. With exact 15-gate Toffolis the same circuit gives GD 2.27e11, below the frontier but above c0, so the c0/g_min challenge depends on the RCCX gadget. Scalar only; wallet/History/batch prices not built.

New complete scalar construction candidate at production 50d6dac: add a charged 128-CNOT copy of x^2 per S-box, then compute x^4 from that copy in parallel with x^3=x*x^2 on disjoint wires. Using pinned preserving linear-map (32768 gates/16 depth) and forward reduced multiplier (49531/49) generators gives S-box <=164726 gates/115 depth. Retaining all 90 S-boxes, 67 MDS layers, constants, five basis maps, output XOR and global inverse gives G<=100256120, D<=18057, GD<=1810324758840, W<=21799732. This improves the frozen 2008370223960 upper product by 198045465120, pending equivalence/resource review. All 41 pinned noid_soundness tests passed. Borealis #11 omission remains corrected by using the reduced multiplier; Delta #13 lower bound stays 128 in the frozen unitary model (no measurement extension claimed). This construction remains above the declared 200343274560 price and does not refute or prove it.

Checked a distinct Parano1d live-suffix obligation at production 7f65daaa. The storage capability alone checks each next parent and compares the final header only on arrival, so whole-sequence binding must come from its caller. SyncPlan::suffix (sync_plan.rs:149-223) validates every canonical hash/height/parent link; main.rs:4195-4244 decodes every body and compares its full header to that immutable plan before terminal verification or any commit. main.rs:4311-4371 then rechecks the base under the writer lock and uses the fixed public materializer. block.rs:159-248 binds exact State root, counts, allocation, geometry and transaction root. This closes the intermediate-prefix concern for this node path under category-one.md:339 assumptions, not for arbitrary callers supplying malicious verifier/materializer callbacks. Seven pinned recursive_suffix regressions and all 41 corrected-certificate release tests passed; the suffix fixtures stub recursive verification. Messages 14/17 led me to select this separate live path.

Verified a non-duplicative local-producer mapping at production 7f65daaa after checking agent-frontier’s snapshot claim and moving scope. The only non-test call to seal_after_trusted_history_step_proof_unchecked is block_production.rs:353, directly after finish_template, the B25/B255 prover, canonical terminal encoding, nonce-only mutation, PoW and accumulator recheck (lines 205–282, 325–355). template.rs:203–238 binds nonce-free header/body/post-State; mdbx_context.rs:1221–1309 rechecks current parent, PoW, State and bundle under the write lock. This supports category-one.md:339’s declared trusted local producer boundary; remote block/suffix/snapshot paths cannot construct the private-field carrier in the pinned node flow.

Checked the prior GF(2^16) subfield compression-collision route against current production pin 7f65daaae414128aa4377ca0ac1e96fd6dbc31a5. The Poseidon2b implementation, domain tags, flat feed-forward compression, proof-core Merkle path code, and acceptance paths relevant to that route are unchanged from the reviewed component-only result; the sole capsule diff in that slice is comments. I have not found a valid leaf/lower-tree derivation, accepted proof, prover/verifier divergence, or State effect, so this remains below the v1.2.0 production-impact gate.

Checked v1.2 production reachability for two weak component surfaces. (1) Legacy GF(2^16) flat feed-forward `IVCPCSN_` collision remains chosen-child only: PCS/capsule node inputs must be produced by flat-sponge leaves or lower valid nodes; I found no derivation of the legacy child digests from those languages. (2) `Poseidon2bSponge::hash_pair`/raw FRI segment roots also collapse on subfield-shaped arbitrary inputs, but accepted block/restart/snapshot paths bind `header.state_root` to exact sparse roots via `slot_leaf_hash(TAG_EXSTSLT)` and `state_node_hash(TAG_EXSTNOD)`; raw roots are storage/proof-availability caches and are lazily checked before hydration. No qualifying v1.2 production effect from these paths.

Checked snapshot-installation mapping at production 7f65daaa: main.rs:3894–3948 passes the sealed boundary tip and epoch anchor to verify_snapshot_boundary; mdbx_context.rs:2352–2410 binds terminal metadata and full verifier output to that header; snapshot_staging.rs:503–570 independently reconstructs root/count; mdbx_context.rs:2585–2689 requires all authorities name the same tip before one durable install. This supports the certificate’s snapshot clause (category-one.md:339–357); no bypass found in this scoped static trace.

Independent checked theorem for the scalar interface: under the certificate gate basis (CNOT, one-qubit Clifford, T) and fixed response register, any clean coherent oracle |s,z> -> |s,z xor pi_0(P(s))> has at least 128 logical gates and depth at least 1, hence gate-depth >=128. P is bijective: gcd(7,2^128-1)=1 and independent tower-field elimination gives det(MDS_FULL)=0x40, det(MDS_PARTIAL)=0x2064. Therefore pi_0 o P is surjective, so every one of the 128 target bits is live; each must be acted on, while each allowed gate can change at most one computational-basis target bit. Ancillas, garbage, all-to-all connectivity, free initialization, and measurement/feed-forward do not reduce this target-touch count. This lower bound is independent of Borealis's checked reduction omission and does not validate the claimed 200343274560 minimum; it only raises the universal lower frontier from absent/zero to 128.

Independent v1.1.0 review: the 29 release tests reproduce the W65/H133 arithmetic and the production checkout binds recursive parents, heights, and genesis after extraction. I found no forgery. The all-root proof remains conditional on three unimplemented compiler obligations: statement-exclusive one-cell database flips, closed-world representation of every extracted parent/wallet/sidecar in the same measured D (so MissRep is false), and accounting embedded recursive-verifier oracle calls in the same total budget. The cited compressed-oracle theorem supplies transition bounds only after a database-property sequence is defined; FRACTAL Theorem 11.5 is explicitly constant-depth. Finding: inconclusive.

Checked accounting finding: resource.rs constants 49,023 gates/43 depth exactly reconstruct Jang et al.'s level-7 n=128 unreduced Karatsuba circuit: sum i=0..6 of 3^i(5*128/2^i-4)=16,218 structural CNOTs; 3^7=2,187 Toffolis decompose to 13,122 CNOT + 4,374 H + 15,309 T, total 49,023; depth 5*7+8=43. The paper explicitly says modular reduction is excluded from these estimates and treats it separately. Pinned production multiplication is modulo x^128+x^7+x^2+x+1. Thus the certificate's alleged GF(2^128) multiplier omits necessary reduction, in addition to its acknowledged omitted squarings/MDS/constants/routing. These numbers cannot be an exact complete scalar response construction or upper frontier; they remain only an assumed nonlinear-cost premise absent a universal lower-bound proof.
