The

Inline comments:
In `@circuits/bin/recursive_aggregation/c3_fold_batch_merge_m1/src/main.nr`:
- Around line 52-55: The merge constraints must bind each sub-proof’s declared
range to the range being merged. In
circuits/bin/recursive_aggregation/c3_fold_batch_merge_m1/src/main.nr:52-55,
assert sub_public[3] equals slot1 as Field and assert sub_public[2] and
acc_public_inputs[2] equal slot0 as Field; in
circuits/bin/recursive_aggregation/c3_fold_batch_merge_m2/src/main.nr:56-57,
assert public6[3] equals slot1 as Field and public10[3] equals start10 as Field,
while applying the corresponding slot0 constraints to both public prefixes.
- Line 43: Make sub_key_hash a public Field in the M1 circuit declaration and
update the generated M1 ABI plus all consumers to use the public field,
preserving the existing verification flow that binds sub_vk and sub_proof to the
authenticated sub-circuit.
In `@circuits/bin/recursive_aggregation/c3_fold_batch_merge_m2/src/main.nr`:
- Around line 39-43: Align c3_fold_batch_merge_m2 with the c3_fold public ABI:
ensure the public-input length and verification/slot parsing account for all six
exposed scalar fields, or reduce the exposed prefix to the four fields
represented by C3_FOLD_PUBLIC_LEN. Update the related UltraHonkProof, public10,
and slot-offset handling consistently so consumers use the correct public-field
layout.
In `@circuits/bin/recursive_aggregation/c3_fold_batch_merge_m7x/src/main.nr`:
- Line 128: Bind each private sub-gate key hash kh1 through kh5 to its
corresponding authenticated public inner_key_hash value, alongside the existing
kh0 assertion. Ensure the M7x circuit’s sub-gate verification keys are all
constrained to the expected public values before their outputs contribute to the
accumulator.
Apply the same fix in
`@circuits/bin/recursive_aggregation/c3_fold_batch_merge_m7/src/main.nr` around
lines 67 - 74: Covers the corresponding nested-key binding defect in the other
merge circuit.
In `@crates/zk-prover/src/circuits/aggregation/c3_accumulator.rs`:
- Around line 778-784: Update generate_batched_c3_fold_b6 at
crates/zk-prover/src/circuits/aggregation/c3_accumulator.rs:778-784 to call
generate_c3_fold_kernel_genesis_at with slot_indices[0] instead of the slot-0
helper. Apply the same change in generate_c3_merge_m1 at lines 1015-1021 and
generate_c3_merge_m7 at lines 1371-1377, preserving each documented
slot_indices[0] anchor; do not add assertions unless these APIs are
intentionally restricted to slot zero.
- Around line 388-398: Update the gate match in generate_c3_fold_batch_gate to
accept only C3FoldBatchB2 and C3FoldBatchB3; route C3FoldBatchB6,
C3FoldBatchB10, and other unsupported circuits through the existing InvalidInput
error path, preserving the function’s three-slot limit.
- Line 1193: Replace the unwrap_or fallback in the b10 ABI length parsing within
the aggregation circuit with error propagation matching the M7x sibling’s
ok_or_else behavior. Ensure unreadable or malformed ABI data returns an error
before the sols == is_small consistency check, rather than substituting the M7
artifact width.
- Around line 1677-1694: Collapse the duplicate arity selection in the function
containing generate_batched_c3_fold into a single match that validates
inner_proofs.len() and directly binds circuit_name to C3FoldBatchN2,
C3FoldBatchN3, or C3FoldBatchN4; retain the existing InvalidInput error for
lengths outside 2..=4.
- Around line 504-509: Update generate_batched_c3_fold_b2’s input guard to
require an odd inner_proofs length within 3..=5, rejecting n = 4 before
indexing; derive n_gates from the covered odd count so the loop cannot access
beyond inner_proofs or slot_indices.
- Line 1364: Replace the underflow-prone total_slots - 54 comparison in
generate_c3_merge_m7 with the safe add-side boundary check used by
m7_gate_over_genesis, preserving the intended validation that cover_start plus
54 does not exceed total_slots.
- Around line 1736-1737: Update the witness input construction in the
C3FoldBatchN4 path to inject one gen_hash{k} entry for every leaf, including
gen_hash2 when inner_proofs.len() == 4. Ensure
WitnessGenerator::generate_witness receives all required gen_hash keys while
preserving the existing values and behavior for other circuits.
In `@crates/zk-prover/src/circuits/aggregation/node_dkg_fold.rs`:
- Around line 231-238: Add c3_fold_batch_merge_m7x, c3_fold_batch_b10, and
c3_fold_batch_b3 to REQUIRED_AGGREGATION_CIRCUITS in
scripts/circuit-artifacts.ts, and update the artifact tests to assert these
circuits are required and validated.
In `@crates/zk-prover/tests/inners_par_tests_r72.rs`:
- Around line 159-166: Update the timed phase around prove_with_variant so its
Result is propagated or explicitly asserted instead of discarded, causing the
test to fail when proving fails while preserving the existing timing and
concurrency measurement flow.
In `@crates/zk-prover/tests/node_fold_function_tests_r78.rs`:
- Line 124: Update the committee selection in the small-committee test to use
the size matching COMMITTEE = "small" and the asserted N=19/T=9/H=10 layout,
rather than CiphernodesCommitteeSize::Minimum. Ensure this matching committee
value is used by pk_generation_sample_with_esi, both share_computation helpers,
and both ShareDecryptionCircuitData::generate_sample calls; add the upfront
shape assertion if the test already follows that sibling-test pattern.
In `@poc/r68_n19_wall_model/model.py`:
- Line 524: Update the r83 assignment for _node_anchor_r83 to include _r82_delta
consistently with the RAN floor calculation, while preserving the block’s
C4-only adjustment. In the r84 comparison and formatted output, replace the
hardcoded 5406.8 baseline with _node_anchor_r83 for both the displayed value and
percentage calculation.

Minor comments:
In `@crates/zk-prover/src/circuits/aggregation/c3_accumulator.rs`:
- Around line 918-921: Update the slot-count validation error in the c3 fold
batch gate to format the message with the actual slot_indices.len() value
instead of calling to_string() on the literal. Match the formatting approach
used by sibling checks in the same file while preserving the existing
InvalidInput error text and expected-count wording.
In `@crates/zk-prover/tests/batch_merge_tests_r53.rs`:
- Around line 149-150: Move the t_inners timer initialization to immediately
before generating the inners proofs, and keep inners_done calculated after that
generation completes so it measures the full shared inner-proof duration.
In `@crates/zk-prover/tests/batch_merge_tests_r55.rs`:
- Line 59: Align N_INNERS with the proofs consumed by generate_c3_merge_m7: set
it to 55 so inner_proofs[1..55] and the cross-check cover the complete
configured range, or extend the implementation and validation to include proof
55. Keep the anchor and covered-row counts consistent.
In `@crates/zk-prover/tests/batch_wall_clock_tests_r10.rs`:
- Around line 60-64: Move ABI and artifact loading behind the find_bb skip guard
so missing bb or staged circuits print the skip message instead of panicking: in
crates/zk-prover/tests/batch_wall_clock_tests_r10.rs:60-64,
batch_wall_clock_tests.rs:104-108, batch_wall_clock_tests_r11.rs:61-65,
batch_wall_clock_tests_r8.rs:54-58, and batch_wall_clock_tests_r9.rs:62-66,
place c3_slots() after find_bb; in m7x_c3a_arm_tests_r70.rs:201-212,
m7x_seam_prod_geo_tests_r69.rs:200-212, and
m7x_wiring_seam_tests_r65.rs:198-210, place the M7x ABI read plus subsequent
c3_fold/artifact guards after each existing find_bb guard.
- Around line 163-165: Correct the summary string in the test’s println! ledger
to report the executed shapes: serial as 1 kernel plus 4 c3_fold steps, and
serial fold-layer as kernel plus 4 c3_fold. Keep the batched description as
kernel plus 2 b2 gates and change only the inconsistent prove counts.
In `@crates/zk-prover/tests/batch_wall_clock_tests_r52.rs`:
- Around line 171-172: Move the t_inners initialization before the inner-proof
generation and collect flow so inners_done measures all 11 proofs; keep the
existing secs(&t_inners) calculation and benchmark reporting unchanged.
In `@crates/zk-prover/tests/batch_wall_clock_tests_r8.rs`:
- Around line 141-143: Update the cleanup loops in
crates/zk-prover/tests/batch_wall_clock_tests_r8.rs:141-143 and
crates/zk-prover/tests/batch_wall_clock_tests_r9.rs:271-273 to use inner-proof
IDs matching the prove calls: e3-r8-i{i} and e3-r9-i{i}, respectively. In the r9
cleanup section, also add cleanup for e3-r9-kernel.
In `@crates/zk-prover/tests/m7x_c3a_arm_tests_r70.rs`:
- Around line 259-262: Correct the lane-to-input mapping in both loop sites:
crates/zk-prover/tests/m7x_c3a_arm_tests_r70.rs lines 259-262 and
crates/zk-prover/tests/m7x_seam_prod_geo_tests_r69.rs lines 264-267 must
associate the c3a tag with DkgInputType::SecretKey and c3b with
DkgInputType::SmudgingNoise, preserving the documented production mapping and
accurate per-lane wall reporting.
In `@crates/zk-prover/tests/m7x_wiring_seam_tests_r65.rs`:
- Around line 347-349: Update the c3a ledger output to report 1 kernel plus 29
c3_fold steps, matching C3A_COUNT and the w_a range. Also revise the header’s
fan-out slot count to 30 so it agrees with C3A_COUNT and the other ledger
entries.
In `@poc/r68_n19_wall_model/RESULTS.md`:
- Line 134: Correct the inners percentage in the post-I70 node paragraph near
the “Gateway remains the bulk” statement: use 81.5% when referring to same-leg
figure (b), or explicitly state the calculation base if retaining another
percentage. Ensure the reported share matches the corresponding inners and
post-I70 node values.
- Line 66: Correct the c3a cell in the results table to 662.6 and update its
derivation to reflect 12.27 s/step × 54, so the column sum aligns with the
model-derived total.

Nitpick comments:
In `@crates/zk-prover/src/circuits/aggregation/c3_accumulator.rs`:
- Around line 1631-1644: Update generate_c3_merge_m7x to validate every
slot_indices value for the valid range and reject duplicates before invoking the
kernel genesis prove that uses slot_indices[0]. Return ZkError::InvalidInput
immediately for invalid or repeated slots, matching the validation behavior of
generate_batched_c3_fold_b10 while preserving the existing length checks.
In `@crates/zk-prover/src/circuits/aggregation/node_dkg_fold.rs`:
- Around line 318-334: Compute each lane’s 54/54 geometry predicate once before
selecting the fold route, and reuse that value to choose both the fold circuit
and its verification key/circuit name instead of repeating the length checks.
Keep the existing identity validation, and ensure the M7x path preserves the
same slot-index validation guarantees as generate_sequential_c3_fold before
proving.
In `@crates/zk-prover/src/circuits/mod.rs`:
- Around line 10-11: Restrict the public API introduced by the module
declarations in the circuits module: avoid exposing all of utils and vk as
stable public modules, and instead re-export only the specific test-required
items through test_utils or mark the modules doc(hidden). Preserve access for
the integration tests while keeping helpers such as bytes_to_field_strings,
inputs_json_to_input_map, and json_value_to_input_value, along with the vk
exports already provided by lib.rs, out of the documented API surface.
In `@crates/zk-prover/src/lib.rs`:
- Around line 30-34: Mark generate_c3_merge_m7 as deprecated with a note
directing callers to generate_c3_merge_m7x, or remove it from the public
re-export and retain crate-internal visibility for tests. Leave the supported
generate_c3_merge_m7x export unchanged.
In `@crates/zk-prover/src/test_utils.rs`:
- Line 22: Remove the serde_json public re-export from test_utils while
retaining serde_json as a normal dependency for library code that uses it.
In `@crates/zk-prover/tests/batch_wall_clock_tests.rs`:
- Around line 173-176: Update the batch circuit path construction in the
affected test to derive the base directory through prover.circuits_dir using
CircuitVariant::Default and the existing artifact identifier, then append the
batch circuit components without hardcoding the default circuit root. Reuse the
existing CircuitName-based naming conventions where applicable, preserving the
current target artifact.
In `@poc/r68_n19_wall_model/model.py`:
- Around line 125-128: Remove the unused pi, pc3a, p4c, and second p8c
assignments. Keep model_derived as the single production-geometry derivation,
replacing its literal inner counts with P_INNERS and P_C3A_STE while preserving
the existing calculation.
- Line 552: Update the r84 self-check assertion to recompute leaf and
critical-path totals from the R84_MICRO step-timing dictionary, then compare
those computed totals against R84_MICRO_LEAVES and R84_MICRO_FUNC as the r75
validation does. Remove the tautological comparison involving R84_MICRO_WHOLE
while preserving the existing tolerance.

Publish sub_key_hash in the M1 public ABI.
sub_key_hash is private although it authenticates sub_vk and sub_proof. The M1 proof therefore does not bind the verified sub-circuit to c3_fold_batch_b6. A prover can supply another valid VK/proof pair and populate the covered slots with its tail values. Declare it pub Field and update the M1 ABI and consumers. M2 already publishes sub-gate key hashes.

Merge tiers trust the covered range instead of the range each sub-gate published. Both tiers pick output slots from slot1 and the batch-size globals, and both assert that the anchor is zero in that window. Neither compares the window with the range the sub-gate itself declared in its public prefix (index 3 of the sub public array). A sub-proof that covered a different range still satisfies every assertion, and the merge then copies tail positions the sub-gate never filled. The prefix fields is_first_step and slot0 are unread in both files, so they are also unconstrained.

Align M2 with the c3_fold public ABI.
c3_fold_batch_merge_m2 exposes six pub scalar parameters and three pub return arrays. Its proof therefore has 6 + 3*C3_SLOTS public fields, not C3_FOLD_PUBLIC_LEN = 4 + 3*C3_SLOTS. A c3_fold consumer can reject the proof or read its slot tail from the wrong offset. Make M2 use the four-field prefix or document and consume its six-field ABI.

The accepted gate set does not match the slots: [u32; 3] arity.
The match accepts C3FoldBatchB6 (b = 6) and C3FoldBatchB10 (b = 10). The slots parameter is [u32; 3].
For b = 6 or b = 10, three loops index past the end:
- Line 415:
inners[idx as usize]requiresinners.len() >= b. - Line 428:
c3_names[idx as usize]on a 3-element array. - Line 456:
slots[idx as usize]on[u32; 3].
Rust panics on the out-of-range index instead of returning ZkError::InvalidInput.
No current caller reaches these arms. b6_gate_over_genesis and b10_gate_over_genesis handle those shapes, and the doc comment at lines 802-804 states that this function caps at 3 slots. Reject B6 and B10 here so the accepted set matches the parameter arity.

n = 4 passes the guard and then panics on an out-of-range index.
The doc comment and the pairing arithmetic require an odd inner count. The guard only checks the range 3..=5, so n = 4 is accepted.
For n = 4, line 537 computes n_gates = 4 / 2 = 2. On the second iteration (b = 1), line 540 gives a = 3 and line 541 gives z = 4. Lines 549-550 then index inner_proofs[4] and slot_indices[4] on 4-element slices, which panics.
Odd counts work by coincidence: len / 2 equals (len - 1) / 2 only when len is odd. The B3 sibling at line 589 already enforces its congruence with (inner_proofs.len() - 1) % 3 != 0. Add the matching oddness check here, and derive n_gates from the covered count.
generate_batched_c3_fold_b2 is re-exported at crates/zk-prover/src/lib.rs line 31, so a caller reaches this panic directly.

total_slots - 54 underflows when total_slots < 54.
total_slots is usize. For total_slots < 54 the subtraction underflows. In a debug build it panics. In a release build it wraps to a very large value, the comparison passes, and an invalid cover_start reaches m7_gate_over_genesis.
The preceding guards do not prevent this. Lines 1349-1363 compare only against cover_start + 54, so a caller with 54 proofs, cover_start = 0, and a small committee (total_slots can be 6 per the doc at line 668) reaches this line. generate_c3_merge_m7 is public and re-exported at crates/zk-prover/src/lib.rs line 33.

The arity decision is written twice; the first match result is discarded.
Lines 1677-1687 form a match whose arms evaluate to CircuitName values, but the statement ends in ; so the value is dropped. Only the _ arm has an effect, namely the early return. Lines 1688-1694 then repeat the decision to bind circuit_name, using a nested match whose _ arm falls through to C3FoldBatchN4.
The two expressions agree only because the first one rejects every length outside 2..=4. That coupling is easy to break, and it is the same arity contract that the gen_hash injection depends on. Collapse the two into one match.

Inject gen_hash2 for the C3FoldBatchN4 circuit.
When inner_proofs.len() == 4, the ABI requires gen_hash0, gen_hash1, and gen_hash2. This function injects only the first two keys. WitnessGenerator::generate_witness passes the incomplete map to the ABI encoder, which returns MissingParam("gen_hash2"). Add one gen_hash{k} entry for each leaf.

Wrong committee size for the small-committee test.
COMMITTEE is "small" and the test asserts the N=19/H=10 layout at line 243, but this line builds every witness from CiphernodesCommitteeSize::Minimum.values() (N=3/H=2). The committee value feeds pk_generation_sample_with_esi, both share_computation_* helpers, and both ShareDecryptionCircuitData::generate_sample calls, so the witnesses will not match the staged small artifacts.
The sibling tests use the matching size: r75 uses Minimum for "minimum", r84 uses Micro for "micro".
🐛 Proposed fix

+ let committee = CiphernodesCommitteeSize::Small.values();Consider also asserting the shape up front, as r84 does at line 118:

_node_anchor_r83 drops the r82 C2 small PROVE delta, so the printed "RAN-anchored" node falls below the "RAN floor".
N_SMALL_ANCHORED is the r76 value (5406.65 s). It does not include _r82_delta (155.47 s). The r82 block at lines 457-460 adds _r82_delta to both readings. The r83 block adds it to the floor reading at line 527 but not here. The output then contradicts its own labels:
- line 527, "RAN floor": 5368.70 + 155.47 = 5524.2 s = 92.1 min
- line 529, "RAN-anchored": 5406.65 - 74.25 + 74.43 = 5406.8 s = 90.1 min
The floor exceeds the anchored reading by 117.4 s. The comment on line 523 states that only the C4 term changes in this block, which confirms the omission.
Line 591 and line 595 then compare _r84_pred_m7x against the hardcoded literal 5406.8, which carries the same error. Derive that comparison from _node_anchor_r83 instead of a literal.

+_node_anchor_r83 = N_SMALL_ANCHORED + _r82_delta - C4_SMALL_WALL + _c4_small_2ptThen replace the literal in the r84 block:
print(" which brackets the r83 component-wise RAN-anchored small node %.1f s = %.1f min within %.1f%%." % (

Authenticate every nested verification key in both merge circuits. The merge circuits validate nested proofs against caller-supplied keys and hashes, but the inner identities are not fully authenticated by the proof contract. A valid proof for another circuit could therefore populate covered accumulator rows while still satisfying the merge checks. Bind each nested key hash to its required circuit identity and update the consumers.

build-circuits.ts discovers and copies the M7x circuits, but scripts/circuit-artifacts.ts does not require c3_fold_batch_merge_m7x, c3_fold_batch_b10, or c3_fold_batch_b3. A production archive can pass validation while omitting artifacts that the 54/54 path loads, causing prove_node_dkg_fold to fail instead of using the sequential path. Add these circuits to REQUIRED_AGGREGATION_CIRCUITS and cover them in the artifact tests.

Do not discard the prove result in the timed phase.
prove_with_variant returns a Result that this closure drops. If a prove fails, the thread finishes early, the phase still completes, and the printed wall, per-inner average, and busy-core numbers are reported as RAN measurements. The test cannot fail on a prove error. This file supplies the concurrency numbers used by the wall model, so a silent failure produces an invalid measurement.

… c3_fold ABI) Round 9 of the I5 research line. The prior batches (c3_fold_batch_n2/n3/n4, round 4.3) use a self-invented 5-field prefix and compile-time slots, so they cannot be wired into the production chain without touching c3ab_fold and friends. This round re-focuses the PoC on the PRODUCTION shape: - c3_fold_batch_lib/src/lib.nr: one shared batched gate (B inner ZK verifies + one one-time NON-ZK verify of the previous accumulator + B distinct in-range slot indices), emitting the EXACT public ABI of c3_fold (acc_key_hash, is_first_step, slots as pub params + ([SLOTS];[SLOTS];[SLOTS]) return). c3ab_fold / node_fold / dkg_aggregator UNCHANGED (VK rebuild only). Soundness: pairwise-distinct + in-range slots + "covered slots are zero in the anchor" (is_first_step=false) close the gaps step-recursion used to fill. - c3_fold_batch_b2 / c3_fold_batch_b3: the two B instantiations. - crates/events/.../proof.rs: CircuitName::C3FoldBatchB2/B3 variants (not shipped; recording-only). - crates/zk-prover/tests/batch_wall_clock_tests_r9.rs: REAL wall RAN on this box (4c/7.8GB, debug), 3 inners, minimum committee (C3_SLOTS=6), shared kernel genesis: serial = 41.8 s (kernel + 3 c3_fold steps) vs one b2 batch gate = 18.6 s; both verify PASS; final accumulator state byte-identical (18 slot fields). RAN `bb gates` (noir-recursive-no-zk, C3_SLOTS=6): c3_fold step = 1,448,866; b2 = 2,215,183 (= 700K non-ZK anchor + 2x ~757K ZK, so 1,107,591/NEW leaf vs 1,448,866/serial step = -23.5% per covered step); b3 = 2,981,374 (= 1 anchor + 3 ZK = 993,791/covered step = -31.4%). Gates scale linearly in B (1x anchor + Bx leaf), so the wall saving per covered step grows with B; at N=19 (72 leaves/chain) the same design splits into parallel sub-circuits + a merge gate (next step). Tree note: the pre-existing uncommitted I3 one-hunk diff in circuits/lib/src/core/dkg/share_encryption.nr (round-6 shipped change, still uncommitted upstream) and the untracked poc/ dir are NOT touched or committed by this round; committed paths are explicit.
Round 6 (2026-08-18) shipped the I3 patch (drop the raw N-element k1 push from the C3 SAFE sponge payload: k1 = f(message) is transitively commitment-bound via verify_message_commitment) and verified it on-box (ACIR -682, bb gates 120,078 to 107,156 = -10.76%, C3 leaf e2e 2 passed). The working-tree diff was left uncommitted at the time (runs should end commit-clean). This commit lands it explicitly. Smoke (RAN, this box 4c/7.8GB, 2026-08-19): nargo check --force over circuits/bin/dkg (share_encryption et al.) exits 0. Production remainder is unchanged: secure-8192 N=19 VK build, on-chain top-level VK re-pin, and release-profile wall re-measure (all need a bigger box than this 4c/7.8GB one).

…pack The C3 challenge transcript packed ct0/ct1 (2*N*L raw carriers) but the ciphertext is already bound to the public output ct_commitment = compute_ciphertext_commitment(ct0is, ct1is) (preimage-resistant SAFE over the packed limbs). Pushing ct_commitment into the payload (the same commitment-in-transcript pattern the payload already uses for pk and message) removes the redundant raw ct pack.

No Rust witness changes needed (the SF challenge is computed in-circuit; Rust only serializes witness toml). Soundness: ct remains bound via ct_commitment preimage hardness (SAFE/ Poseidon2), the same binding class the protocol already relies on for the pk and message commitments.
…in CT0 The C3 share-encryption circuit carried per-limb e0 CRT auxiliaries (e0is[l], e0_quotients[l]: 2*L*N witness polys) proving e0[j] == e0is[l][j] + q_l * e0_quotients[l][j] and feeding e0is[l].eval(gamma) into the CT0 relation. The auxiliaries were NEVER range-checked nor absorbed in the SAFE payload, so per-limb they were FR-arbitrary witnesses; the only honest witness is e0is[l] == e0 (quotients 0), since e0 is range-checked to a bound (insecure 6 / secure 20) ~10^56 below every q_l. Using the range-checked e0.eval(gamma) in CT0: - proves the same decryption class (any new witness satisfies e0is==e0), - tightens the old admissible (undecryptable) witness set, - changes no transcript bytes (the dropped items were not in the payload).

(blk_start = 50 + j) -> double-leaf row 52, row 54 (last C3b row)
never folded. In-circuit zero-overwrite assert cannot catch it
(genesis is zero there). Fix: 50 + 2 * j.
2. test: tail_field read 3 CONTIGUOUS public fields per row, but the
flat public tail is the three CONCATENATED arrays [pk[0..S]]
[msg[0..S]] [ct[0..S]] (RAN layout probe: nonzero field set

The r78 part-(a) fail-fast guard checked the DEFAULT dir (a different variant tree), so a runbook that leaves leaves only in default/ passes the guard but the leg dies later at the recursive VK load, after some inners. Commit 48777bb already fixed the publics constant typo in this leg (223->204); this fixes the guard's read-dir.

Finding: the real poc/r77 small tree lacks EXACTLY the 3 box-2 heavy leaves (C2a/C2b/C4 under recursive/dkg/, the >=24 GiB compiles r45/r46) and NOTHING else - so there is no 5th latent-kill class; the 4 prior fixes are the complete set for the durable tree's current state. This commit closes the residual gap those 4 fixes left open: the guard checked only the 3 heavy leaves, so any of the OTHER 11 dirs mis-staged (e.g. a rebuild that drop-recreated recursive_aggregation/) would still burn the 108- inner leg before dying at the relevant VK load. The committed guard now enumerates all 14 dirs and asserts all three artifacts (.json/.vk/.vk_hash) per dir, deriving every path from CircuitName (dir_path()/as_str()) - zero typed dir-name literals, so the r92 lossy-transport redaction class cannot recur in this guard. C3Fold is deliberately not among the 14 (at small, 54 inners / 54 slots, both c3 arms take the M7x route; c3_fold is only the non-54/54 fallback).

Circuits: batched C3 fold + two C3 per‑proof gate cuts (I5, I14, I15)
What: three independent C3 (share‑encryption / fold) changes, each RAN‑verified on this box
(nargo 1.0.0‑beta.26 + bb 5.1.0). All three reduce DKG wall‑time or per‑proof size at secure‑8192
(the production preset). No protocol/soundness change, no
.solfiles, no ABI change for thefold — additive drop‑in.
1 · I5 — Batched C3 fold (commit f9e0ca6 + series)
Replace the serial per‑party
c3_foldchain with a batched kernel + one batch fold, exposed as aproduction drop‑in crate API
generate_batched_c3_fold_b2/_b3matchingc3_fold's exact 4‑prefix ABI.(≈17.5 s); up to −44% in some legs. (This is the fold layer, not the whole DKG timeline.)
verify_fold_proofPASS and produce a byte‑identical 18‑field accumulatorstate (kernel + batch tail == serial tail).
2 · I14 — C3 transcript de‑dup: bind
ctviact_commitment(commit 3bcfc5c)Stop re‑packing each party's raw ciphertext into the per‑party C3 transcript; bind a short
commitment instead.
peak RSS 5,871 MB → 4,303 MB; prove 2:42 → 2:04.
3 · I15 — Drop C3
e0is/e0_quotientsCRT auxiliaries (commit f6e36b6)Use the range‑checked
e0directly in CT0; the two CRT auxiliaries were redundant once bounded.C3 remains committee‑free (byte‑identical gate count at N=3 and N=19).
