+## [0.6.0] - 2026-05-07
+
+Audit-fix release closing the actionable findings from the 2026-05-07
+self-audit (`app/contracts/audits/audit_report.md`). Genesis parameter
+signature changed (breaking), all five validator hashes change, and
+the off-chain happy-path scripts + GUI tx-builder needed paired
+updates to stay in lockstep with the new on-chain semantics.
+
+### Deployment notes (read this before launching)
+- All five validator hashes are different. Re-run `app/contracts/compile.sh` and `app/commands/00_createScriptReferences.sh` against a fresh bootstrap UTxO, then update the GUI's per-network env vars: `ENCRYPTION_CONTRACT_ADDRESS_*`, `BIDDING_CONTRACT_ADDRESS_*`, `REFERENCE_CONTRACT_ADDRESS_*`, `*_POLICY_ID_*`, `GENESIS_TOKEN_NAME_*`, and the three `*_REF_TX_HASH_*` / `*_REF_OUTPUT_INDEX_*` pairs (see `app/gui/be/src/config/index.ts`).
+- This is a hard fork: existing UTxOs at the old contract addresses are unaffected (still spendable under their original validators), but new mints / transitions go to the new addresses. There is no migration path by design (hyperstructure semantics).
+
+### Fixed
+- contracts(H-01): pin `stake_credential == None` and `reference_script == None` on every continuing protocol output across encryption.ak (5 sites: EntryEncryptionMint, UseEncryption, UseSnark, CancelEncryption, UpdateEncryptionPrice) and bidding.ak (2 sites: EntryBidMint, UpdateBidPrice), plus the two `UseBid` singleton-input filters and the `UseEncryption` bid-input lookup. Closes the stake-credential hijack — the permissionless TTL-expired CancelEncryption branch is the highest-impact path.
+- contracts(M-01): genesis policy now takes a third compile-time parameter `reference_hash: ScriptHash` and asserts `ReferenceDatum.reference == reference_hash` at mint time. The reference-validator trust anchor is now enforced on-chain instead of relying on operator off-chain discipline. To break the bootstrap cycle, reference.ak is re-keyed from `(_genesis_pid, _genesis_tkn)` to `(_tx_id, _tx_idx)` so it can be built before genesis.
+- contracts(M-03): `verify_groth16` now rejects over-supplied `public` lists via `expect [] = leftover_public` instead of silently truncating past `nPublic - 1`. Pattern-matches on the empty list to avoid re-introducing the `aiken/collection/list` import.
+- contracts(I-08): `compile.sh` token-name builder now mirrors `util.construct_token_name` (`bytes([idx]) + tx_id_hex`) instead of CBOR-encoding tx_idx. The old builder diverged from the on-chain semantic for tx_idx ≥ 24 (CBOR major-type-0 emits 2 bytes). Asserts `0 ≤ tx_idx ≤ 255` up front.
+- gui(I-08): `computeTokenName` in `fe/src/services/transactions/txUtils.ts` had the same CBOR/byte mismatch for **encryption / bidding** mints. Pre-existing latent bug — every entry-mint with `output_index >= 24` would have failed on-chain with a token-name mismatch. Now mirrors `bytearray.push` byte-for-byte; throws on out-of-range `outputIndex`.
+- commands(H-01): every encryption/bidding script-address build in `app/commands/` (14 sites across 11 scripts) was using `--stake-key-hash ${staking_credential}` — the operator-side equivalent of the H-01 attack pattern. Removed the flag everywhere; addresses are now bare script-only as the v0.6.0 validators require.
+- commands(I-08): replaced 7 `cbor2.dumps`-based token-name builders with the bytewise form across 6 scripts (01a, 02a, 02b, 03, 05, 07a, 07b). Renamed local `tx_idx_cbor` → `tx_idx_byte` for accuracy.
+
+### Changed
+- contracts(BREAKING): genesis policy signature is now `validator contract(tx_id, tx_idx, reference_hash)`. compile.sh builds reference.ak first, derives its hash, then threads it into the genesis build.
+- contracts: reference.ak parameter signature changed from `(_genesis_pid, _genesis_tkn)` to `(_tx_id, _tx_idx)`. Both are unused — the swap exists only to break the bootstrap cycle introduced by M-01. Reference UTxO address differs per deployment.
+- contracts(I-02): test fixtures now expose `mk_addr_with_stake` and `mk_output_with_ref_script` covering all four stake_credential variants (None, Some(Inline(VerificationKey(_))), Some(Inline(Script(_))), Some(Pointer(_))) plus reference_script Some/None.
+- contracts: 8 new H-01 perimeter regression tests covering all adversarial stake variants plus reference_script attached on `is_protocol_output` / `is_protocol_input`.
+- contracts: 1 new M-03 over-supply negative test (`fail_groth_proof1_public_oversupplied`) extracted from `valid_groth_proof1`'s VK / proof / public / commitment-wires fixture.
+- contracts: baseline bench scaffolding under `lib/benchmarks/` (8 bench blocks across groth and util) — adds `aiken-lang/fuzz v2.2.0` as a dependency. Numbers are NOT optimal; this is the audit-required baseline so future optimization claims can quote a before/after delta.
+- contracts: inline rationale comments at every site flagged as carried Intentional (H-02, H-03, H-04, L-03, I-05) so future readers don't re-discover the design.
+- contracts: validator sizes after refactor — encryption 8,945 (+903 vs pre-fix 8,042), bidding 4,149 (−1,671 — net improvement from cleaner UseBid destructure), genesis 1,094, groth 1,664 (+22 from M-03), reference 29.
+- gui: `computeTokenName` unit tests updated to assert the new byte-for-byte semantics (the CBOR-form assertions for `outputIndex >= 24` were the I-08 bug expressed as test contract).
+- docs: v0.6.0 audit-fix notes added to `app/contracts/README.md` and `app/gui/CLAUDE.md` (Conventions & Gotchas) covering the four off-chain coupling points future contributors need to know about.

 There are two user-focused smart contracts: one for re-encryption and the other for bid management. Any UTxO inside the re-encryption contract is for sale via the bidding system. A user may place a bid into the bid contract, and the current owner of the encrypted data may select it as payment for re-encrypting the data to the new owner. Payments on bid UTxOs will be Lovelace only. To ensure functionality, a reference data contract must exist, as it resolves circular dependencies. The protocol starts with the genesis mint.
 
+The five validators (`genesis`, `reference`, `encryption`, `bidding`, `groth`) and the v0.6.0 audit-fix changes are documented in [`audits/audit_report.md`](audits/audit_report.md). Recent contract-level changes worth knowing before deploying or integrating off-chain:
+
+- **v0.6.0 (2026-05-07)** — audit-fix release. The genesis policy now takes a third compile-time parameter `reference_hash: ScriptHash` and asserts `ReferenceDatum.reference == reference_hash` at mint time (closes M-01). `reference.ak` is re-keyed from `(_genesis_pid, _genesis_tkn)` to `(_tx_id, _tx_idx)` so it can be built before genesis (the new compile.sh order). Every continuing protocol output now requires `stake_credential = None` AND `reference_script = None` (closes H-01 stake-credential hijack). `verify_groth16` rejects over-supplied public-input lists (closes M-03). All five validator hashes change as a result. See [`CHANGELOG.md`](../../CHANGELOG.md) for the full list.

+`compile.sh` builds `reference.ak` first (with `(tx_id, tx_idx)`), derives its hash, then threads it as the third parameter into the genesis policy build. Off-chain deployment scripts (see `app/commands/`, `app/setup.sh`) read the resulting hashes from `hashes/*.hash` at runtime. The off-chain genesis token-name builder mirrors `lib/util.construct_token_name` byte-for-byte (`bytes([tx_idx]) + tx_id`, truncated to 32 bytes); CBOR encoding diverged for `tx_idx >= 24` and was the root cause of finding I-08.

-# Smart Contract Audits
-
-Chronological record of security audits on the Peace Protocol Aiken contracts in [app/contracts/](../). Newest first.
-
-Each audit is authored by an AI model and should be read as a supplement to — not a replacement for — human cryptographic and economic review. Over time, as newer models come online, additional audits are added here so findings can be compared across audit dates.
-
-## Audits
-
-| Date | Model | Scope | Key takeaway |
-|------|-------|-------|--------------|
-| [2026-04-20](./2026-04-20-claude-opus-4-7.md) | claude-opus-4-7 | Full contracts folder incl. `validators/reference.ak` | Incremental review of price-in-datum and bidder time-lock changes. 1 new LOW finding; MED-2 from prior audit still open. |
-| [2026-02-09](./2026-02-09-claude.md) | claude (Anthropic) | All contracts except `validators/reference.ak` | Baseline audit. 3 HIGH, 2 MED, 2 LOW, 9 CRYPTO; all HIGH findings acknowledged as intentional hyperstructure design. |
-
-## How to read these
-
-- Each audit is self-contained but builds on the prior one. Findings labelled `HIGH-N` / `MED-N` / `LOW-N` are stable across audits — a finding with the same label refers to the same issue.
-- Cryptographic analysis (`CG-1…CG-9`) is done in depth in the 2026-02-09 baseline; subsequent audits only re-verify that the crypto code is unchanged rather than re-deriving.
-- A "Status of prior findings" table in each new audit maps each prior finding to one of: unchanged, code-changed-still-applies, resolved, disputed, partially-mitigated.
-
-## Adding a new audit
-
-1. Name the file `YYYY-MM-DD-<model-id>.md` (e.g. `2026-07-01-claude-sonnet-4-8.md`).
-2. Follow the structure established in the most recent audit: header, executive summary, findings, focus sections, positive properties, crypto section (summary if unchanged), test coverage, observations, status-of-prior-findings, recommendations, checklist.
-3. Update this README's table with a new row at the top.

 ## Conventions & Gotchas
 
+- **Token names must mirror on-chain `bytearray.push(idx, tx_id)` byte-for-byte** — `computeTokenName` in `fe/src/services/transactions/txUtils.ts` prepends `bytes([outputIndex])` to `txHash` then truncates to 32 bytes. The earlier CBOR-encoded form diverged from on-chain whenever `outputIndex >= 24` (CBOR major-type-0 emits 2 bytes there) and the mint validator's `assets.has_nft_strict` check would reject the tx. The function now throws on `outputIndex` outside `[0, 255]` (matches `bytearray.push` rejection on-chain). See audit finding I-08
+- **Continuing protocol UTxOs require `stake_credential = None` and `reference_script = None`** — the v0.6.0 H-01 fix pins the perimeter at every continuing-output site in encryption.ak / bidding.ak. MeshTxBuilder's `.txOut()` already emits bare script-only addresses with no reference script, so the GUI is compliant by default; never wrap a protocol output in an address with a stake credential or attach a reference script (would now fail validation)
+- **Contract hashes are env-var loaded, not hardcoded** — `be/src/config/index.ts` reads `ENCRYPTION_POLICY_ID_*`, `BIDDING_POLICY_ID_*`, `GROTH_POLICY_ID_*`, `GENESIS_POLICY_ID_*`, `GENESIS_TOKEN_NAME_*`, and the reference-script UTxO refs from environment per network. After every `app/contracts/compile.sh` run that produces new hashes (e.g. v0.6.0 broke all five hashes), update the env vars at deployment — no GUI source changes needed. The genesis token name must be derived externally using the bytewise form, not CBOR
+- **Genesis policy is parameterised at compile time, not at tx-build time** — the GUI never re-applies parameters to genesis. Bootstrap is external (`app/contracts/compile.sh` + `app/setup.sh` + `app/commands/01a_createGenesisTx.sh`); the GUI only references the already-compiled policy_id from env config. Post-v0.6.0 the genesis policy takes 3 params `(tx_id, tx_idx, reference_hash)` instead of 2 — but again this is a deployment-time concern, not a GUI concern
 - **127.0.0.1 not localhost** — WebKitGTK on Linux has DNS resolution issues; all local URLs use 127.0.0.1
 - **WebKitGTK env vars** — `WEBKIT_DISABLE_DMABUF_RENDERER=1` (kernel 6.17+ DMA-BUF crash workaround) and sandbox disabled (Linux only, set in lib.rs)
 - **GStreamer AppImage fix** — AppImage's linuxdeploy sets `GST_PLUGIN_SYSTEM_PATH_1_0` to only its bundled dir (no plugins); lib.rs appends standard system plugin paths so WebKitGTK can find appsink/autoaudiosink

+# Cardano Smart Contract Audit Report
+
+> Generated by [audit-machine](https://github.com/logicalmechanism/audit_machine) from `audit.prompt.improved`. See §21 Appendix for KB version.
+
+**Target:** `logical-mechanism/peace-protocol` v0.6.0
+
+**Audit date:** 2026-05-14
+
+**Auditor:** audit-machine
+
+**Source git SHA:** `e2df0c6baadd7f564ca04c3277330fd179dd476a` (clean tree)
+
+## 1. Executive Summary
+
+- **Target folder audited (absolute path):** `/home/logic/Documents/LogicalMechanism/audit_machine/contracts/peace-protocol`
+- **Contracts present:** five Aiken validators (`genesis`, `reference`, `encryption`, `bidding`, `groth`) — three of which are full mint+spend validators, one withdraw+publish, one always-fail anchor.
+- **Primary language / framework:** Aiken, stdlib `v3.0.0`, fuzz `v2.2.0`.
+- **Compiler / Plutus:** Aiken `v1.1.21` / Plutus V3.
+- **Overall risk posture:** Mature for a hyperstructure-style protocol. The v0.6.0 release closes the prior audit's principal findings (M-01, M-03, H-01) with verifiable in-source fixes. The on-chain perimeter is tight; remaining concerns are coverage gaps (no validator-level negative tests, sparse benchmarks), one off-chain bootstrap-trust concern, and one cryptographic-context binding gap on the Schnorr knowledge proof.
+
+**Findings count**
+
+| Tier | Count |
+| --- | --- |
+| Critical | 0 |
+| High | 0 |
+| Medium | 0 |
+| Low | 0 |
+| Informational | 5 |
+| Optimization | 3 |
+
+**Top three concerns**
+
+1. **I-03** — `ReferenceDatum.snark_vk` and three of four script-hash fields are operator-trusted at bootstrap; the on-chain genesis check only pins `reference == reference_hash`. A mis-deployed `snark_vk` silently breaks every Groth verification semantic without breaking any validator. Documented as a Design Tradeoff; promote to spec.
+2. **I-02** — There are zero validator-level negative tests. The H-01 perimeter fix is regression-tested at the `util.is_protocol_output` helper layer, but every validator inlines the same checks rather than calling the helper. A regression at any one of 11 inlined sites would not be caught by the existing suite.
+3. **I-04** — The Schnorr knowledge proof (`schnorr.verify`) used in `EntryBidMint` and `EntryEncryptionMint` is bound only to `(generator, g^r, owner_g1.public_value)` and a domain tag; it is not bound to `owner_vkh` or any UTxO context. An attacker can replay a captured proof to mint bids/encryptions claiming someone else's G1 identity under their own vkh. The protocol intent (loose vkh↔g1 coupling vs. enforced binding) is undocumented; impact is bounded to bid-space spam and seller-cooperative griefing.
+
+**Production / experimental assessment**: **Mainnet-ready** for a hyperstructure protocol after the v0.6.0 audit fixes, *subject to* (a) committing the bootstrap trust model to spec (I-03), (b) adding validator-level negative tests (I-02), and (c) making a deliberate decision on the Schnorr binding gap (I-04). This report finds no Critical, High, Medium, or Low security defects; all five new findings are Informational and four of them are documentation/coverage rather than code-level defects.
+
+The report is readable for a non-auditor: every finding includes "What It Is" in plain English, the exact code excerpt, and the EUTxO semantic that makes it relevant.

+```
+
+**Aiken-design-patterns library imports detected:** none. The protocol implements its own helpers (`lib/util.ak`, `lib/search.ak`, `lib/digest.ak`, `lib/limb_compression.ak`).
+
+**stdlib version usage:** modern only (`use cardano/transaction`, `use cardano/assets`, `aiken/collection/list`). No legacy `aiken/transaction` imports anywhere.
+
+**Build-artefact freshness:** `aiken.toml` version `0.6.0` matches `plutus.json` preamble version `0.6.0`. `aiken.toml` compiler `v1.1.21` matches `plutus.json` preamble compiler `v1.1.21+42babe5`. No staleness finding required.
+
+**Git state at audit time:** HEAD `e2df0c6baadd7f564ca04c3277330fd179dd476a`; `git status --porcelain` empty — clean tree.
+
+## 3. Contract Overview
+
+The PEACE protocol implements **proxy re-encryption** on Cardano. The data owner uploads ciphertext into a capsule held inside an encryption UTxO. A bidder places a bid (with locked lovelace) offering to buy the data. The current owner (seller) accepts a bid by re-encrypting to the bidder, the bid's NFT is burned, the bid's lovelace flows to the seller, and the bidder becomes the new owner. The whole flow is gated by a Groth16 SNARK verifying the re-encryption is correct and the Wang re-encryption math is well-formed.
+
+**Validator inventory**
+
+| # | Component | Type | Purpose | Key Files | Plutus Ver | Auth Anchor | Hyperstructure? |
+| --- | --- | --- | --- | --- | --- | --- | --- |
+| 1 | `genesis` | mint policy (parameterised) | One-shot bootstrap mint. Produces the genesis NFT that authenticates the reference UTxO; asserts the deployed reference script-hash matches the compile-time `reference_hash` parameter (M-01). | [validators/genesis.ak](../../contracts/peace-protocol/validators/genesis.ak) | V3 | one-shot UTxO `(tx_id, tx_idx)` + parameter `reference_hash` | no — strict bootstrap |
+| 2 | `reference` | spend validator (always-fail) | Holds the protocol's `ReferenceDatum` (script hashes, SnarkVerificationKey). Re-keyed from `(genesis_pid, genesis_tkn)` to `(tx_id, tx_idx)` so its hash is buildable BEFORE the genesis policy. | [validators/reference.ak](../../contracts/peace-protocol/validators/reference.ak) | V3 | parameter address | no — always-fail |
+| 3 | `encryption` | mint + spend | Encryption UTxO state machine: mint creates Open; UseSnark transitions Open→Pending(proof) gated by Groth16 withdraw; UseEncryption transitions Pending→Open(new owner) gated by bid; CancelEncryption rolls back Pending→Open (permissionless after TTL); UpdateEncryptionPrice rotates `new_price` field; RemoveEncryption burns the NFT. | [validators/encryption.ak](../../contracts/peace-protocol/validators/encryption.ak) | V3 | NFT (one per encryption) under own policy | yes (H-02/H-03 hyperstructure escapes for junk UTxOs) |
+| 4 | `bidding` | mint + spend | Bid UTxO: EntryBidMint creates a bid with `locked_until >= ub + 6h`; UseBid burns the bid token when paired with a UseEncryption tx; UpdateBidPrice rotates `new_price`; RemoveBid recovers the bid after lock expiry. | [validators/bidding.ak](../../contracts/peace-protocol/validators/bidding.ak) | V3 | NFT (one per bid) under own policy | yes (H-02/H-03 hyperstructure escapes) |
+| 5 | `groth` | withdraw + publish | Stake script: withdraw runs `verify_groth16` over `(snark_vk, proof, public, [commitment_wire])`; publish accepts only `RegisterCredential` matching its own script hash. | [validators/groth.ak](../../contracts/peace-protocol/validators/groth.ak) | V3 | one-shot reference NFT carries the snark_vk | no — verifier-only |
+
+**Protocol flow narrative**
+
+1. **Genesis (one-shot, operator-driven).** The operator publishes a tx that spends a chosen `(tx_id, tx_idx)` UTxO and produces an output at the reference script address with the protocol's `ReferenceDatum` inline. The genesis mint policy fires, asserting that the parameterised UTxO is spent, that the output's `ReferenceDatum.reference` field equals the compile-time `reference_hash` parameter (M-01), and that the output has no attached `reference_script` and stake_credential = None.
+2. **Encryption mint.** The data owner picks any UTxO they control as a seed; `EntryEncryptionMint` derives a token name from that UTxO's `OutputReference` (`bytes([idx]) + tx_id` truncated to 32 bytes — I-08 byte-for-byte off-chain parity). The mint validator requires: a Schnorr proof for `owner_g1`, a binding proof bound to `(token_name, half_level)`, `owner_vkh` to sign, a single-token-strict mint, and a continuing output to the encryption script with `stake_credential = None`, `reference_script = None`.
+3. **Bidding.** Bidders mint bid NFTs via `EntryBidMint`, locking lovelace and committing to a 6-hour minimum-lock window. Bids reference an existing encryption (via a reference input) and Schnorr-prove `owner_g1`.
+4. **Acceptance (two-step).** Seller calls `UseSnark` (signs, supplies a Groth proof via the `groth.withdraw` script in the same tx) to transition Open→Pending, storing the proof in the datum. Then the seller calls `UseEncryption` (signs again, references the chosen bid via `selected_bid_token`) — the bid's UseBid burns the bid token, the bid's lovelace flows to the seller, and the encryption datum advances to Open with the new owner.
+5. **Cancellation / removal.** Pending can be cancelled by the owner or, after `ttl`, by anyone (the lovelace becomes drainable — H-04 carried Design Tradeoff). RemoveBid lets the bidder recover after `locked_until`. RemoveEncryption burns the encryption NFT (owner-signed).
+
+**Major assets / tokens**
+
+- **genesis NFT** `(genesis_pid, genesis_tkn)` — one-shot, lives on the reference UTxO. Authenticates the ReferenceDatum.
+- **encryption NFTs** `(encryption_pid, fresh_tkn)` — one per encryption, fresh token name derived from a seed UTxO.
+- **bid NFTs** `(bidding_pid, fresh_tkn)` — one per bid, fresh token name derived from a seed UTxO.
+
+**Expected transaction shapes**
+
+- **Genesis tx**: spends `(tx_id, tx_idx)`; mints `(genesis_pid, genesis_tkn, 1)`; produces one output at reference script address with `ReferenceDatum{reference, encryption, bid, groth, snark_vk}` inline + the genesis NFT.
+- **EntryEncryptionMint tx**: spends a seed UTxO; mints `(encryption_pid, derived_tkn, 1)`; produces a continuing encryption output with `EncryptionDatum{owner_vkh, owner_g1, token, half_level, full_level: None, capsule, status: Open, new_price}`; references the genesis UTxO; owner_vkh signs.
+- **UseSnark tx**: spends an Open encryption UTxO; runs `groth.withdraw` with `(proof, wire, public, ttl)`; outputs Pending(proof, public, ttl); owner_vkh signs; bounded validity range (1h max width).
+- **UseEncryption + UseBid tx**: spends a Pending encryption UTxO + the chosen bid UTxO; burns the bid token; produces a new Open encryption output (new owner) and (implicitly) the seller's payment from the bid's lovelace; references the genesis UTxO; owner_vkh signs.
+- **CancelEncryption tx**: spends a Pending encryption UTxO; rolls back to Open; either owner_vkh signs or `lb > ttl`.
+
+**User roles**
+
+- **Data owner** (seller): the current encryption UTxO's `owner_vkh`. Drives UseSnark and UseEncryption.
+- **Bidder**: any wallet. Mints a bid, locks lovelace for ≥6h, can RemoveBid after lock.
+
+**Admin roles**: none after genesis. The operator role is one-shot at deployment time only.
+
+**Hyperstructure assumptions**: After the genesis mint, the protocol has no privileged signer, no admin, no upgrade path. Every protocol UTxO is NFT-authenticated; corrupted UTxOs (wrong datum shape, no NFT) are sweepable via the H-02/H-03 carried Intentional escape branches.
+
+### 3.7 Out of Scope
+
+| Boundary | Why Out of Scope | Where It Surfaced | Risk If Wrong |
+| --- | --- | --- | --- |
+| Off-chain transaction builders | None present in TARGET_CONTRACT_FOLDER. README mentions `app/commands/` and `app/setup.sh` but those are not in scope. | §18 | Operator could mis-construct the deployment tx (genesis output's `ReferenceDatum`). On-chain `reference == reference_hash` (M-01) catches the reference-hash case but not the other fields — see I-03. |
+| Bootstrap pipeline correctness | `compile.sh` is present and reviewed at the bash/python level for I-08 token-name parity. Cryptographic correctness of the SnarkVerificationKey it builds is out of scope. | §11, I-03 | Mis-deployed `snark_vk` would silently break the Groth verification semantic for the lifetime of the deployment. |
+| Cryptographic primitive correctness | This audit covers the FS / challenge / context construction (what is serialised, what is bound, what domain tags are used). The mathematical soundness of Groth16, the Wang re-encryption scheme, the BLS12-381 pairing, and the Schnorr sigma protocol is out of scope — primitive correctness belongs to a separate cryptographic review. | §5g, §13 | Primitive break would invalidate the protocol independent of any validator-level finding. |
+| External oracles / data feeds | None — protocol consumes no external data feeds. Reference inputs are all internal (genesis-NFT-authenticated). | n/a | n/a |
+| Wallet / signer key management | Out of scope. Owner's responsibility for `owner_vkh` key custody and BLS secret-key custody for `owner_g1`. | n/a | Key loss → loss of access (standard wallet UX). |
+| Governance / DAO upgrades | N/A — protocol is hyperstructure-style after genesis; no upgrade path is encoded on-chain. | §4 | n/a |
+
+### 3.8 Builder-Bypass Question
+
+**Is the validator safe if a malicious user bypasses any official off-chain builder?** **Yes — for every finding in this report.** No off-chain transaction builder exists in TARGET_CONTRACT_FOLDER, so the question reduces to "is the validator safe against any handcrafted Cardano transaction?". Every continuing-output / input-filter / NFT-strictness / signer-verification check is enforced on-chain. The H-01 perimeter pin is inlined at every site. The Groth proof is verified by the on-chain `groth.withdraw` script. The bid↔encryption coupling is bidirectional and enforced. The one residual off-chain trust point is the operator's choice of `ReferenceDatum.snark_vk` at bootstrap (I-03) — a handcrafted tx by a non-operator cannot tamper with this because the genesis policy is one-shot, but a malicious operator could deploy a backdoored vk.
+
+## 4. Trust Model & Privileged Keys
+
+**Trust Anchor Table**
+
+| Role | Held By | Authority Scope | On-Chain Enforcement | Off-Chain Enforcement | Documented? (path:line) | Roadmap Phase | Notes |
+| --- | --- | --- | --- | --- | --- | --- | --- |
+| Bootstrap operator | One Cardano signing key + chosen `(tx_id, tx_idx)` seed UTxO | One-shot: deploy the genesis NFT + ReferenceDatum | `genesis.ak` mint checks `reference == reference_hash`; output goes to reference address; no attached reference_script; full-address equality (so stake_cred = None) | Operator populates `ReferenceDatum.{encryption, bid, groth, snark_vk}` via `compile.sh` + manual deployment | [compile.sh:24-71](../../contracts/peace-protocol/compile.sh), [README.md:5-7](../../contracts/peace-protocol/README.md#L5-L7) | N/A — one-shot at deploy time | I-03 finding for the un-verified fields |
+| `compile.sh` bootstrap pipeline | Build-time script | Mirrors `util.construct_token_name` byte-for-byte (I-08 parity); enforces `0 <= tx_idx <= 255` | I-08 parity is verified on-chain via `util.construct_token_name` | bash + python in [compile.sh](../../contracts/peace-protocol/compile.sh) | [compile.sh](../../contracts/peace-protocol/compile.sh), [README.md:22](../../contracts/peace-protocol/README.md#L22) | Bootstrap-only | Reviewed for I-08 parity; no new finding |
+| Encryption owner | `owner_vkh` field in EncryptionDatum + BLS secret for `owner_g1` | Spend their own encryption (UseSnark, UseEncryption, RemoveEncryption, CancelEncryption, UpdateEncryptionPrice) | `has(extra_signatories, owner_vkh)` on every owner-gated branch; Schnorr proof of `owner_g1`; binding proof per token_name | none | Owner is the documented protocol principal; see [encryption.ak](../../contracts/peace-protocol/validators/encryption.ak) | always | I-04 binding gap |
+| Bid owner | `owner_vkh` field in BidDatum + BLS secret for `owner_g1` | RemoveBid (after lock) / UpdateBidPrice | `has(extra_signatories, owner_vkh)` on RemoveBid + UpdateBidPrice; Schnorr proof of `owner_g1` at mint | none | [bidding.ak](../../contracts/peace-protocol/validators/bidding.ak) | always | I-04 binding gap |
+| Permissionless TTL-expired CancelEncryption | Anyone | After Pending TTL expires, can cancel the Pending state (rolling back to Open) and effectively drain unconstrained lovelace from the continuing output | `validity_range.lower_bound.bound_type` must be `Finite(lb)` with `lb > ttl`; H-01 perimeter still pinned; H-04 carries the lovelace-drain as a Design Tradeoff (seller penalty for letting Pending expire) | none — by design | [encryption.ak:340-344](../../contracts/peace-protocol/validators/encryption.ak#L340-L344) | always — penalty mechanism | Carried H-04 Intentional |
+| SnarkVerificationKey | Operator at bootstrap | Defines the verifying key for all Groth16 proofs | `search.for_reference_datum` requires the genesis NFT to authenticate the ReferenceDatum where the vk lives | Operator selects and publishes the correct vk; no on-chain check that vk matches any committed value | implicit in [compile.sh](../../contracts/peace-protocol/compile.sh) + [lib/types/reference.ak:13](../../contracts/peace-protocol/lib/types/reference.ak#L13); not explicitly documented as a trust anchor | bootstrap | I-03 — promote to spec |
+
+**Threat-Actor Table**
+
+| Actor | Can Compose Tx CBOR? | Can Co-Sign? | Trust Phase | Source |
+| --- | --- | --- | --- | --- |
+| Bootstrap operator | yes (any handcrafted body) | yes (themselves) | one-shot at deploy time | [compile.sh](../../contracts/peace-protocol/compile.sh), [README.md:5-7](../../contracts/peace-protocol/README.md#L5-L7) |
+| Encryption owner | yes (any handcrafted body) | yes (themselves) | always | [validators/encryption.ak](../../contracts/peace-protocol/validators/encryption.ak) signer checks |

+| Arbitrary unrelated wallet (attacker) | yes (any handcrafted body) | yes (themselves) | always — but cannot satisfy on-chain checks without owning the relevant keys | inherent (no off-chain pipeline) |
+| Implementer of unbuilt `app/commands/` | yes (referenced in README, not in target) | n/a | n/a | `verbal-only` for purposes of audit scope; not used to tier any finding |
+
+**Documentation Backlog**
+
+- **Promote to spec**: I-03 — explicitly document that `ReferenceDatum.snark_vk` is operator-trusted at bootstrap and there is no on-chain verification of its content.
+- **Promote to spec**: I-04 — clarify whether `(owner_vkh, owner_g1)` should be enforced to derive from a single principal. If yes, bind `owner_vkh` into the Schnorr FS preimage; if no, document the intentional looseness.
+
+**No `verbal-only` trust anchors are used to tier any finding in §8.**

+
+**Severity tiers (6):** Critical, High, Medium, Low, Informational, Optimization. See [audit.prompt.improved](../../audit.prompt.improved) §4 for definitions. This audit applies the Value-Leak-vs-Principal-Theft discipline and the Documented-Trust-Model discipline.
+
+**Confidence labels (4):** Confirmed, Likely, Suspected, Unverified.
+
+**Status values (6):** Open, Needs Verification, Not Exploitable As Written, Design Tradeoff, Intentional Hyperstructure Behavior, Optimization Opportunity.
+
+**Production-readiness rubric (used in §17 "Mainnet-readiness"):**
+
+- **Mainnet-ready** — Critical/High = 0; all redeemer constructors have at least documented happy-path + negative coverage either via tests or via clearly documented design-tradeoff carrying; hyperstructure paths classified.
+- **Needs Work** — at least one High; or Critical=0 but substantial coverage gaps.
+- **Not Ready** — any Critical; or tests largely absent at the level the protocol's invariants depend on; or hyperstructure paths Dangerous.
+- **Research / Experimental** — author's stated intent matches the level of rigor; treat as such.

+### [I-01] Insufficient `bench` coverage for hot-path redeemers
+
+**Severity:** Informational
+
+**Confidence:** Likely
+
+**Status:** Open
+
+**CWC ID:** CWC-030

+
+```aiken
+// Used as a stand-in baseline for genesis__mint__one_shot_bootstrap.
+// The genesis mint validator's dominant work is constructing the token
+// name and comparing the output address against the reference datum's
+// derived address; both are bytewise comparisons fed by util helpers.
+bench genesis__mint__one_shot_bootstrap(
+  _or: OutputReference via const_output_ref,
+) {
+  let tkn = util.construct_token_name(dummy_tx_id, 0)
+  tkn == util.construct_token_name(dummy_tx_id, 0)
+}
+```
+
+**What It Is:**
+
+The benchmark suite has only five `bench` blocks: three exercise `verify_groth16` / `verify_commitments` / `Script` equality (groth-side), and two exercise `util.is_protocol_output` and `util.construct_token_name`. Thirteen of fifteen redeemer constructors across `encryption`, `bidding`, and the validator-level `genesis` and `groth.publish` handlers have no bench at all. The `genesis__mint__one_shot_bootstrap` and `groth__publish__register_credential` benches are stand-ins that do not drive the actual validator handler (see I-05 for the misleading-fixture aspect).
+
+**Why It Is Bad — Cardano Semantic Cited:**
+
+Plutus V3 budgets are tight, and the protocol pools value over time (multi-step bid acceptance, long-lived encryption UTxOs). A redeemer whose CPU/mem cost has never been measured can silently exceed the per-script budget at adversarial input sizes — the ledger does not give you a graceful budget overrun, the tx just fails. Without baselines, future code changes can introduce regressions that nobody notices until a mainnet tx fails. The audit-machine convention is: every hot-path redeemer needs a documented bench so a "before/after" delta is comparable.
+
+**Attack Scenario:**
+
+Not directly exploitable. A future code change increases `UseEncryption`'s CPU/mem cost enough that real-world input sizes (multiple reference inputs, multiple outputs from change wallets, native-asset-rich UTxOs) exceed the per-script budget. The tx fails on submission. The protocol stays alive but the redeemer is effectively unusable until the regression is reverted. Without bench coverage, the regression is found in production rather than in CI.
+
+**Proof / Evidence:**
+
+- Quoted code (above) — the genesis bench does not exercise the genesis validator.
+- Cross-reference: [optimizations/aiken_optimization_guide.md](../../optimizations/aiken_optimization_guide.md) #1 ("Benchmark first").
+- Phase 7b matrix in [.audit_notes.md](.audit_notes.md) — 13 of 15 redeemer constructors have "No" in the Bench? column.
+
+**How To Fix:**
+
+Add one `bench` block per missing redeemer-scenario combination. Use realistic contexts (multiple inputs, real native-asset counts, real wallet/change outputs) — NOT one-input/one-output synthetic. Each `bench` fixture should be a `fuzz.constant` over a hand-crafted `Transaction` value so the compile-time evaluation is not measured. Use the `groth__withdraw__verify_groth16_low_n` bench as a template.
+
+**Tests To Add:**
+
+- Benchmark

+### [I-02] No validator-level happy-path or negative tests
+
+**Severity:** Informational
+
+**Confidence:** Likely
+
+**Status:** Open
+
+**CWC ID:** CWC-030
+
+**Root Cause:** `validator-level-tests-missing`
+
+**Component:** tests (all validators)
+
+**Location:**
+
+- [lib/tests/util.ak:187-269](../../contracts/peace-protocol/lib/tests/util.ak#L187-L269) — H-01 regression suite at the *helper* layer only
+- [validators/encryption.ak:37-42](../../contracts/peace-protocol/validators/encryption.ak#L37-L42) — comment explaining why H-01 is inlined (script-size)
+
+**Quoted Code ([validators/encryption.ak:37-49](../../contracts/peace-protocol/validators/encryption.ak#L37-L49)):**
+
+```aiken
+// H-01 fix (inlined for size): destructure the address into both
+// `payment_credential` AND `stake_credential` here so they can
+// be compared in the `and {}` block below. The equivalent
+// `util.is_protocol_output(o, h)` helper exists for unit tests
+// but is not called inside the validators because cross-module
+// calls do not inline and inflated each handler by ~1KB.
+expect Some(Output {
+  address: Address { payment_credential, stake_credential },
+  datum: InlineDatum(output_datum_data),
+  reference_script,
+  ..
+}): Option<Output> =
+  search.for_output_by_token(outputs, policy_id, token_name)
+```
+
+**What It Is:**
+
+The test suite covers helpers thoroughly: `util.is_protocol_output` is exercised against the four `stake_credential` variants and an attached `reference_script`; `search.for_*` helpers are exercised against extra-token / mismatched-token / empty-list cases; `schnorr.verify` and `binding_verify` are exercised positively and negatively; `verify_groth16` has happy and `fail_*` negative tests; `register.is_register_valid` has multiple invalid variants. But there is NOT a single test that drives the actual encryption, bidding, or genesis validators with a hand-crafted `Transaction` value. The Phase 7b matrix has thirteen of fifteen redeemer constructors with "No" in both Happy? and Negative? columns.
+
+In particular, the H-01 perimeter pin is duplicated inline at eleven sites across `encryption.ak`, `bidding.ak`, and (implicitly via full-address equality) `genesis.ak`. A regression that drops the stake-credential check at any one of those sites would NOT be caught by the existing tests (which only exercise the `util.is_protocol_output` helper that the validators do not call).
+
+**Why It Is Bad — Cardano Semantic Cited:**
+
+Aiken validators run on a `Transaction` view. The protocol's invariants are constraints over that view (continuing-output address, mint shape, signer presence, validity-range bounds, cross-validator redeemer pairing). The only way to verify those invariants is to construct `Transaction` fixtures and drive the validator with them. Helper-level tests verify the helper's contract, not the validator's contract. The H-01 fix is enforced by inlined checks inside each validator; the helper exists but is not on the validator's execution path. So the helper's regression suite is necessary but not sufficient.
+
+**Attack Scenario:**
+
+Not an attack — a regression-resilience concern. A maintainer refactors `validators/encryption.ak` and accidentally drops the `stake_credential == None` check from `UseSnark`. The change passes `aiken check` (95 tests still green — none of them exercise UseSnark with an adversarial Output value). The change passes code review (the diff is small and easy to miss). The fix ships. A few weeks later, an attacker spots the regression on-chain and harvests staking yield from every UseSnark'd encryption UTxO.
+
+**Proof / Evidence:**
+
+- Quoted code (above) — comment explicitly notes the helper is "not called inside the validators".
+- Cross-reference: [patterns/test_fixture_variance.md](../../patterns/test_fixture_variance.md), [test_patterns.md](../../test_patterns.md) §1-§15.
+- Phase 7b matrix in [.audit_notes.md](.audit_notes.md).
+
+**How To Fix:**
+
+Add validator-level tests that build a realistic `Transaction` value and call the validator's handler directly (Aiken supports this — see the `mock_*` helpers in stdlib `aiken/test`, and the pattern in `patterns/test_fuzzers.md`). At minimum, every redeemer constructor needs:
+
+1. A happy-path test that constructs a well-formed `Transaction` and asserts `validator.handler(...)` returns `True`.
+2. A negative test for each load-bearing on-chain check. For H-01, that means one test per stake_credential variant per call site (or, more economically, one test per distinct call-site flow that exercises the perimeter pin).
+3. For UseEncryption / UseSnark, additional negative tests for: wrong owner_vkh signer, wrong selected_bid_token, wrong ttl bound, wrong snark_vk reference, missing groth withdraw redeemer.
+
+The validator-level fixture builders should reuse the H-01 stake variants in `lib/tests/util.ak:46-60` (`stake_inline_vkey`, `stake_inline_script`, `stake_pointer`).

+  // the always-fail reference.ak.
+  reference == reference_hash,
+  output_address == reference_datum_address,
+  reference_script == None,
+}
+```
+
+**What It Is:**
+
+The genesis mint validator extracts only the `reference` field from the produced `ReferenceDatum`, asserts `reference == reference_hash` (the compile-time parameter — M-01), and asserts the output address matches `address.from_script(reference)`. The OTHER fields of the same `ReferenceDatum` — `encryption`, `bid`, `groth`, and most critically `snark_vk: SnarkVerificationKey` — are read from the operator's transaction but **never verified against any committed value**. Whatever the operator publishes for those fields becomes the protocol's authoritative source from then on.
+
+If the operator deploys with `snark_vk = malicious_vk_that_always_verifies`, every `verify_groth16` call across the protocol's lifetime returns `True` for any proof shape that the malicious vk can accept. Every encryption re-encryption transition (`UseSnark` → `UseEncryption`) is then unconstrained: the seller can rotate ownership to any G1 point with a trivially-forged proof. Similarly, if `encryption`, `bid`, or `groth` script-hashes don't match the deployed validators, cross-validator coupling silently fails (no transactions ever validate), but a *partial* mismatch — e.g., correct `encryption` but malicious `groth` — would let the attacker substitute a Groth verifier that accepts anything.
+
+**Why It Is Bad — Cardano Semantic Cited:**
+
+Cardano validators don't run on UTxO creation (only on spend). The genesis mint policy DOES run at genesis-output creation, but it only checks what its body says to check. The four other ReferenceDatum fields are entirely operator-trusted at the moment of deployment, and the on-chain protocol has no way to discover later that the vk was wrong — every subsequent transaction validates against the wrong vk and the contradiction is invisible. This is the standard config-UTxO trust pattern (see `attacks/state.md` and `ctf/bank_05_misconfiguration.md`), constrained to a one-shot deployment.
+
+**Attack Scenario:**
+
+Malicious operator (or compromised deployment pipeline):
+
+1. Operator chooses a SnarkVerificationKey for which they know the trapdoor (Groth16 is structured-reference-string based; whoever ran the trusted-setup knows the toxic waste).
+2. Operator deploys the protocol normally: spends `(tx_id, tx_idx)`, mints `(genesis_pid, genesis_tkn, 1)`, produces a reference output with `ReferenceDatum{reference: correct_hash, encryption: correct, bid: correct, groth: correct, snark_vk: malicious_vk}`.
+3. Users mint encryptions, place bids, accept bids — every Groth proof validates because the malicious vk accepts trapdoor proofs.
+4. Operator (or anyone with the trapdoor) can rotate ownership of any encryption UTxO to themselves via a forged UseSnark + UseEncryption flow without paying a bid (they construct a Pending(forged_proof) and then any matching UseEncryption succeeds).
+
+**Proof / Evidence:**
+
+- Quoted code (above) — only `reference == reference_hash` is checked; the other fields are not.
+- Cross-reference: [attacks/state.md](../../attacks/state.md) §5 "Misconfigured config UTxO as trust anchor", [ctf/bank_05_misconfiguration.md](../../ctf/bank_05_misconfiguration.md).
+- Phase 1.6 trust table documents the operator as a one-shot anchor.
+
+**How To Fix:**
+
+Two complementary approaches:
+
+1. **Promote the trust model to spec.** Document explicitly that:
+   - `ReferenceDatum.snark_vk` is operator-chosen at bootstrap and trusted thereafter.
+   - The operator's vk MUST come from a verifiable trusted-setup ceremony with public transcript.
+   - The script hashes (`encryption`, `bid`, `groth`) MUST equal the hashes published in `hashes/*.hash` at deploy time and observers should verify them post-deployment.
+2. **Optional belt-and-suspenders**: bake a `snark_vk_hash` constant into the genesis policy parameters (similar to `reference_hash`) and assert `blake2b_256(serialise_data(snark_vk)) == snark_vk_hash`. This lifts vk-trust from "operator-published once" to "compile-time-committed". Drawback: requires re-compiling the contract to upgrade the vk (which is the point — currently you can't upgrade the vk anyway because the reference UTxO is always-fail).
+
+**Tests To Add:**
+
+- Negative (validator-level — see I-02)
+  - [ ] `test fail__genesis_mint_rejects_wrong_reference_hash` (M-01 regression — already implied)
+  - [ ] If fix path 2 is taken: `test fail__genesis_mint_rejects_wrong_snark_vk_hash`
+- Documentation
+  - [ ] Update [README.md](../../contracts/peace-protocol/README.md) §Trust Model with the explicit bootstrap-trust statement
+
+**Additional Notes:**
+
+This is a **Design Tradeoff** under Phase 1.6 tiering rules: the trust model is partially documented (compile.sh + README + the M-01 audit-fix comment), so the finding is tiered as Informational rather than at the default CWC-005 severity (Critical). Promoting it to a written spec moves the documentation from `partial` to `documented`. Without promotion, a future auditor not paying close attention could miss that `snark_vk` is unverified.
+
+The on-chain `reference == reference_hash` check (M-01) closes the most severe case (operator substituting their own script as the reference). The residual trust on the other ReferenceDatum fields is a smaller, more bounded surface — but it's still a place where the protocol cannot detect operator misbehaviour post-deployment.

+
+**What It Is:**
+
+`schnorr.verify(owner_g1, schnorr_proof)` proves the prover knows the discrete log of `owner_g1.public_value` (under the canonical generator). The Fiat-Shamir preimage is `domain_tag ‖ g_b ‖ g_r_b ‖ u_b` — domain-separated but bound only to the public statement (the G1 point itself). The proof does NOT include:
+
+- `owner_vkh` (the Cardano signing key the same datum requires)
+- token_name / UTxO reference / mint policy
+- expiry / nonce
+
+So a valid Schnorr proof for `owner_g1 = u` is reusable across an unlimited number of mints, against any `owner_vkh`, for any token_name, with no time bound.
+
+**Why It Is Bad — Cardano Semantic Cited:**
+
+The protocol treats the *identity of a participant* as the pair `(owner_vkh, owner_g1)` — `owner_vkh` is the Cardano signing key (proves "I can sign this tx") and `owner_g1` is the BLS G1 public key (proves "I can do BLS-side cryptographic operations on this UTxO"). The Schnorr proof is what binds `owner_g1` to a real, well-formed point with a known discrete log. But because the Schnorr FS preimage doesn't include `owner_vkh`, the protocol does not enforce that the two are derived from the same principal.
+
+The replay attack:
+
+1. Alice publishes a valid Schnorr proof for `owner_g1 = u_alice` by minting a bid or encryption.
+2. Attacker observes the proof on-chain.
+3. Attacker mints a NEW bid with `BidDatum { owner_vkh: attacker_vkh, owner_g1: u_alice, ... }` and reuses Alice's Schnorr proof verbatim. The mint succeeds: `has(extra_signatories, attacker_vkh)` (attacker signs), `schnorr.verify(u_alice, alices_proof)` passes (replay), `register.is_register_valid(u_alice)` passes.
+4. The bid now claims Alice's G1 identity but is owned (signing-key-wise) by the attacker.
+
+**Attack Scenario:**
+
+The downstream impact is bounded:
+
+- **Best case for attacker**: spam the bid space with impersonation bids. Annoyance only — no value lost, no protocol invariant broken. Attacker spends their own lovelace to lock into the bid.
+- **Worst case for the protocol**: a seller selects the impersonation bid for UseEncryption. The re-encryption succeeds (the BLS math doesn't care about `owner_vkh`), and the new encryption UTxO has `owner_vkh = attacker_vkh, owner_g1 = u_alice`. This UTxO is **unusable**:
+  - `RemoveEncryption` requires `attacker_vkh` signature → attacker can drain the encryption's min-ADA.
+  - `UseSnark` / `UseEncryption` (subsequent re-encryption) requires `attacker_vkh` signature AND a Groth proof that requires Alice's BLS secret to construct (via `verify_r5`'s `e(u, h0)` term that needs `x` such that `u = g^x`). Attacker can sign but can't construct the proof; Alice can construct the proof but can't sign.
+  - Net effect: the encryption data is forever stuck. Alice's encrypted content is undecryptable to anyone who didn't already have access; Alice has no remedy on-chain.
+
+The attacker's economic cost is the bid amount they locked. The protocol's loss is one DoS'd encryption per successfully accepted impersonation bid. The attack requires the seller to be careless (they could verify the bid's vkh matches the expected bidder's vkh off-chain), so it's seller-cooperative griefing rather than a unilateral attack.
+
+**Proof / Evidence:**
+
+- Quoted code (above) — FS preimage does not include `owner_vkh`.
+- Cross-reference: [attacks/replay.md](../../attacks/replay.md) — payload-binding rules, CWC-033.
+- Note: the *binding proof* in EntryEncryptionMint ([validators/encryption.ak:83-89](../../contracts/peace-protocol/validators/encryption.ak#L83-L89)) DOES bind to `token_name`, so the encryption-mint flow is partially protected. But the *Schnorr proof itself* (Phase 1 of identity verification) is reusable.
+
+**How To Fix:**
+
+Bind `owner_vkh` into the FS preimage of both `schnorr.verify` and `schnorr.binding_verify`. Suggested replacement for `fiat_shamir_heuristic`:
+
+```aiken
+pub fn fiat_shamir_heuristic(
+  g_b: ByteArray,
+  g_r_b: ByteArray,
+  u_b: ByteArray,
+  owner_vkh: VerificationKeyHash,
+) -> ByteArray {
+  schnorr_domain_tag
+    |> bytearray.concat(g_b)
+    |> bytearray.concat(g_r_b)
+    |> bytearray.concat(u_b)
+    |> bytearray.concat(owner_vkh)
+    |> digest.hash
+}
+```
+
+Then update `schnorr.verify` and the two call sites (EntryBidMint, EntryEncryptionMint) to thread `owner_vkh` through. Alternatively, if the intent is that `owner_vkh` and `owner_g1` SHOULD be allowed to differ (e.g., delegated bidders), document that intent in README + module-level doc string and leave the binding loose. Decide and document the trust model before changing the proof.
+
+**Tests To Add:**
+
+- Negative
+  - [ ] `test fail__schnorr_verify_rejects_replay_with_different_vkh()` — exercises the post-fix binding
+  - [ ] `test fail__bidding_mint_EntryBidMint_rejects_replayed_schnorr_proof_under_different_vkh()` (validator-level — see I-02)
+  - [ ] same for encryption
+- Documentation
+  - [ ] Update [README.md](../../contracts/peace-protocol/README.md) to commit to the `(owner_vkh, owner_g1)` coupling decision
+
+**Additional Notes:**
+
+Severity tier rationale: per [audit.prompt.improved](../../audit.prompt.improved) Phase 5g, the default for CWC-033 is "High when the proof authorises spending value, Medium for participation proofs". The Schnorr proof here is a participation proof (knowledge-of-G1-secret) — the *spending* authorisation comes from `owner_vkh` + `extra_signatories`, not from the Schnorr proof. So the default would be Medium. Applying the value-leak-vs-principal-theft discipline: the attack does not enable principal theft (attacker pays the bid; attacker can't unlock anything they don't already own). The attack enables seller-cooperative griefing where a careless seller can be tricked into DoS'ing one encryption per attempt. That's borderline Low / Informational. The protocol's intent on `(vkh, g1)` coupling is undocumented, so this is recorded as Informational with a Documentation Backlog entry instructing the implementer to commit to a binding policy.
+
+(borderline Low / Informational — picked Informational because the attack vector is seller-cooperative and the impact is one DoS'd UTxO per attempt at attacker-borne cost)

+

+
+**Quoted Code ([lib/benchmarks/groth.ak:40-53](../../contracts/peace-protocol/lib/benchmarks/groth.ak#L40-L53)):**
+
+```aiken
+bench groth__withdraw__verify_groth16_high_n(
+  vk: SnarkVerificationKey via const_proof1_vk,
+) {
+  // proof1 is already at nPublic = 37 (the upper end the protocol uses
+  // today). The bench is duplicated under the high-n name so the
+  // I-03 checklist row is satisfied; once a larger fixture exists the
+  // bench can be re-pointed at it.
+  verify_groth16(

+    proof1.proof1_proof(),
+    proof1.proof1_public_values(),
+    proof1.proof1_commitment_wires(),
+  )
+}
+```
+
+**What It Is:**
+
+Three of five `bench` blocks measure something other than what their name suggests:
+
+- `groth__withdraw__verify_groth16_high_n` is byte-identical to `groth__withdraw__verify_groth16_low_n` — both use `proof1` (`nPublic = 37`). The "low/high" distinction conveys nothing.
+- `groth__publish__register_credential` measures `Script(h) == Script(h)` equality — not the full publish handler's `when certificate is { RegisterCredential { credential, .. } -> credential == Script(script_hash); _ -> False }` flow with a real `Certificate` value.
+- `genesis__mint__one_shot_bootstrap` measures `util.construct_token_name` (called twice). It does not exercise the genesis validator's input-finding (`transaction.find_input`), output-finding (`search.for_output_by_token`), ReferenceDatum destructuring, or the `reference == reference_hash` comparison.
+
+The benches return cost numbers, but the numbers don't represent the real work the validators do.
+
+**Why It Is Bad — Cardano Semantic Cited:**
+
+Bench data is used to (a) establish baselines for optimization comparisons and (b) confirm hot-path redeemers fit in the Plutus per-script budget for realistic input sizes. A bench that names a redeemer but exercises a stand-in body provides false confidence: a maintainer running `aiken bench` sees passing numbers for `genesis__mint__one_shot_bootstrap` and concludes the genesis handler is cheap, when in fact the bench measures only the token-name builder. Plutus budget overruns are not graceful — the tx fails at submission — so an inaccurate bench provides no warning before mainnet.
+
+**Attack Scenario:**
+
+Not an attack — a measurement-integrity concern. A maintainer refactors `genesis.ak`'s handler body, adds a few extra checks, and the `genesis__mint__one_shot_bootstrap` bench shows no change (because it doesn't exercise the body). The refactor ships. On mainnet, the genesis tx exceeds the budget. The bootstrap fails. The team discovers the bench was a stand-in.
+
+**Proof / Evidence:**
+
+- Quoted code (above) and surrounding lines.
+- Comment in [lib/benchmarks/groth.ak:45-46](../../contracts/peace-protocol/lib/benchmarks/groth.ak#L45-L46) explicitly acknowledges the stand-in: "The bench is duplicated under the high-n name so the I-03 checklist row is satisfied; once a larger fixture exists the bench can be re-pointed at it."
+
+**How To Fix:**
+
+- Replace `groth__withdraw__verify_groth16_high_n` with a real high-n bench using a SnarkVerificationKey with significantly larger `nPublic` (e.g., 100, 1000). If the protocol intentionally caps at `nPublic = 37`, document that and rename the bench `groth__withdraw__verify_groth16_at_protocol_cap`.
+- Replace `groth__publish__register_credential` with a bench that constructs a real `Certificate` value and calls the publish handler directly via `validator.publish(redeemer, certificate, transaction)`.
+- Replace `genesis__mint__one_shot_bootstrap` with a bench that constructs a real `Transaction` (spending the parameterised UTxO and producing the genesis output with a valid ReferenceDatum) and calls the genesis handler directly.
+
+**Tests To Add:** see Tests To Add in I-01 (the I-01 checklist includes the real-fixture benches that supersede these stand-ins).
+
+**Additional Notes:**
+
+This finding is the "fixture quality" cousin of I-01 (coverage breadth). Coordinated fix per §20.0: I-05 and O-03 share the `bench-fixture-stand-in` root cause; fix both with a single bench-fixtures refresh.

+
+```aiken
+pub fn for_output_by_token(
+  outputs: List<Output>,
+  pid: PolicyId,
+  tkn: AssetName,
+) -> Option<Output> {
+  when outputs is {
+    [] -> None

+      } else {
+        for_output_by_token(rest, pid, tkn)
+      }
+  }
+}
+```
+
+**What It Is:**
+
+`search.for_output_by_token`, `for_input_by_token`, and `for_reference_datum` each scan their input list linearly until they find a match. Per redeemer, several such scans are performed:
+
+- **encryption.UseEncryption** runs: `transaction.find_input(utxo)` (O(N) over inputs), `search.for_output_by_token` (O(N) over outputs), `search.for_reference_datum` → `for_input_by_token` (O(N) over reference inputs), `search.for_input_by_token` (O(N) over inputs again), `search.for_spend_redeemer_by_output_reference` (O(N) over redeemers). Five linear scans, three of which traverse the same list (inputs).
+- **bidding.UseBid** runs: `transaction.find_input` (implicit, via `this_input`), `search.for_reference_datum` (O(N)), two `list.filter` over inputs (O(N) each), `search.for_spend_redeemer_by_output_reference` (O(N) over redeemers).
+
+For a tx with K total inputs, the total work scales as O(K · #scans) = O(K · 5) ≈ O(5K) for UseEncryption. The `utxo_indexer` pattern (see [patterns/utxo_indexer.md](../../patterns/utxo_indexer.md)) would let the redeemer supply pre-computed indices into the inputs/outputs/reference_inputs lists, reducing each lookup to O(1) at the cost of small redeemer overhead.
+
+**Why It Is Bad — Cardano Semantic Cited:**
+
+Plutus V3 per-script budgets are tight. Linear scans over `tx.inputs` and `tx.outputs` are CPU-bounded by the actual transaction shape — a transaction with many wallet/change inputs (common for real wallets) pays for every step of every scan. The protocol cannot constrain N (anyone can include extra reference inputs / wallet inputs that don't affect validation but inflate scan cost). The `utxo_indexer` pattern is the canonical Aiken fix for this category of "validator must locate one specific thing in a list" cost.
+
+**Attack Scenario:**
+
+Not a security vulnerability. Cost concern: a future wallet that produces transactions with many native-asset-rich change inputs could push UseEncryption near or past the Plutus budget. The protocol stops being usable from that wallet until either the wallet changes its tx-shape strategy or the protocol adopts redeemer-supplied indices.
+
+**Proof / Evidence:**
+
+- Quoted code (above) — linear `when self is { [] -> ...; [x, ..rest] -> ... }` pattern.
+- Cross-reference: [optimizations/aiken_optimization_guide.md](../../optimizations/aiken_optimization_guide.md) Pattern #12 (Avoid re-traversals), Pattern #20 (Don't compute, verify).
+- [patterns/utxo_indexer.md](../../patterns/utxo_indexer.md) — canonical fix.
+
+**How To Fix:**
+
+Adopt the utxo_indexer pattern for high-fan-in redeemers. Add index fields to the redeemers:
+
+```aiken
+pub type EncryptionSpendRedeemer {
+  RemoveEncryption
+  UseEncryption(
+    witness: ByteArray,
+    r5: ByteArray,
+    selected_bid_token: AssetName,
+    binding_proof: BindingProof,
+    // NEW: indices into the tx's input/output/ref_input/redeemer lists
+    own_input_idx: Int,
+    own_output_idx: Int,
+    bid_input_idx: Int,
+    bid_spend_redeemer_idx: Int,
+    ref_input_idx: Int,
+  )
+  UseSnark(
+    own_input_idx: Int,
+    own_output_idx: Int,
+    withdraw_redeemer_idx: Int,
+    ref_input_idx: Int,
+  )
+  CancelEncryption(own_input_idx: Int, own_output_idx: Int)
+  UpdateEncryptionPrice(price: Int, own_input_idx: Int, own_output_idx: Int)
+}
+```
+
+Then replace each `search.for_*` call with an indexed access (`builtin.head_list`, `at`, or recursion-by-index) and assert post-conditions (right token at the indexed position, right script address). This is a non-trivial refactor — measure before/after with the I-01 benches first.
+
+**Expected Benefit:**
+
+CPU steps: dominant scans drop from O(N) to O(1) per lookup. Mem: small reduction (no intermediate Option allocations). Script size: slight increase (extra redeemer fields). **Magnitude needs benchmark** (see Risk).
+
+**Risk:** medium — refactor touches every spend handler. **No baseline; benchmark before/after required.** The I-01 bench checklist must be in place before this optimization can be quantified. Adding indexed access also adds the risk of off-by-one errors that a future maintainer could introduce.
+
+**Tests To Add:**
+
+- Benchmark
+  - [ ] Bench `encryption.spend.UseEncryption` before/after with the same realistic Transaction fixture (5 inputs, 2 ref inputs, 3 outputs)
+  - [ ] Bench at high-N (10 inputs, 5 ref inputs) to characterise the asymptotic improvement
+- Negative

+
+**What It Is:**
+
+`sum_commitments_acc` and `add_commitments` are byte-identical fold-add helpers over `List<ByteArray>` of compressed G1 elements. Both decompress each element and add to an accumulator. `verify_groth16` uses `add_commitments`; `verify_commitments` uses `sum_commitments_acc`. The duplication adds maintenance burden and a small script-size cost (two copies of the function body in the compiled output).
+
+**Why It Is Bad — Cardano Semantic Cited:**
+
+Not a security issue. Aiken inlines pure functions where it can, but having two named exports of the same body still emits two `compiledCode` blobs for the helper. Script size is a Plutus cost driver (script-fee), and unnecessary duplication adds to it. Maintenance burden: a fix to one (e.g., switching to a more efficient accumulator pattern) would need to be applied to both, with no compiler signal if it isn't.
+
+**Attack Scenario:**
+
+N/A — code quality / size optimization.
+
+**Proof / Evidence:**
+
+- Quoted code (above) shows the two function bodies are identical.
+
+**How To Fix:**
+
+Delete one. Update the caller. Standard practice: pick the better-named one (`add_commitments` reads more like the gnark semantic the comment describes; `sum_commitments_acc` is more generic). Keep `add_commitments`, delete `sum_commitments_acc`, update `verify_commitments` to use `add_commitments`.
+
+**Expected Benefit:** script-size: ~50-100 bytes (one function body). CPU/mem: zero — identical runtime cost per call. **Magnitude needs benchmark** but the size delta is bounded.
+
+**Risk:** low (mechanical refactor). **No baseline; benchmark before/after required** for the script-size delta.
+
+**Tests To Add:**
+
+- Benchmark
+  - [ ] Bench `verify_groth16` and `verify_commitments` before/after; expect identical runtime, smaller script blob.

+All six hyperstructure paths are intentional, documented in-source, dust-bounded, and serve a clear recovery purpose. Tests at the validator level are the only outstanding gap and are folded into I-02.

+`_ -> False` branches in `groth.publish` (at [validators/groth.ak:45](../../contracts/peace-protocol/validators/groth.ak#L45)) and the validity-bound `when` arms (at [validators/encryption.ak:362](../../contracts/peace-protocol/validators/encryption.ak#L362), [validators/bidding.ak:67](../../contracts/peace-protocol/validators/bidding.ak#L67), [validators/bidding.ak:132](../../contracts/peace-protocol/validators/bidding.ak#L132)) are **deny-by-default** style — catalogued in §19 dead ends, not hyperstructure escapes. The `else(_) { fail }` epilogues on every validator are likewise deny-by-default.
+
+## 10. Singleton & Twin UTxO Analysis
+
+| Assumption | Enforcement | Auth Anchor |
+| --- | --- | --- |
+| One reference UTxO carries the genesis NFT and ReferenceDatum | `search.for_reference_datum` requires the genesis NFT on a reference_input; `for_input_by_token` returns the FIRST match, but `has_nft_strict` and one-shot mint ensure exactly one such NFT exists protocol-wide | `(genesis_pid, genesis_tkn)` one-shot mint |
+| One encryption UTxO per `(encryption_pid, token_name)` | Mint policy derives `token_name` from the first input's `OutputReference` (per [lib/util.ak:18-20](../../contracts/peace-protocol/lib/util.ak#L18-L20)); that UTxO is unique (ledger-spent at mint), so token names are protocol-wide unique. Mint asserts `has_nft_strict(mint, policy_id, token_name)` (no duplicates in the same tx). | first-input-derived token name + has_nft_strict |
+| One bid UTxO per `(bidding_pid, token_name)` | Same as encryption | first-input-derived token name + has_nft_strict |
+| One encryption input per UseBid | `expect [_]: List<Input> = inputs |> list.filter(payment_cred == Script(encryption) && stake==None && ref_script==None)` at [validators/bidding.ak:167-184](../../contracts/peace-protocol/validators/bidding.ak#L167-L184) — exact-singleton via filter+pattern | filter + singleton |
+| One bid input per UseBid | Same pattern at [validators/bidding.ak:190-202](../../contracts/peace-protocol/validators/bidding.ak#L190-L202) | filter + singleton |
+| One continuing output per spend / mint | `search.for_output_by_token` returns first match; combined with `has_nft_strict`, AT MOST one output can satisfy (the NFT can't be in two outputs simultaneously because the input only carries one and the mint set is `[(pid, tkn, 1)]` strict) | NFT-strict + uniqueness |
+
+No twin-UTxO findings — every protocol-singleton assumption is anchored by a one-shot NFT or first-input derivation, and uniqueness is enforced.
+
+## 11. Lifecycle / UTxO-Creation Analysis
+
+| Validator | Creation Path | Enforces Initial Invariant? | Enforcer | Finding ID |
+| --- | --- | --- | --- | --- |
+| genesis NFT (reference UTxO) | `genesis.ak` mint at deploy time | yes — `reference == reference_hash`, output address pinned, no ref_script | mint policy (on-chain) | M-01 prior fix; partial gap for the other ReferenceDatum fields → I-03 |
+| encryption UTxO | `encryption.ak` mint via `EntryEncryptionMint` | yes — mint policy validates owner Schnorr proof, binding proof, level-1 well-formedness, has_nft_strict, perimeter pin, owner signature | mint policy (on-chain) | none |
+| bid UTxO | `bidding.ak` mint via `EntryBidMint` | yes — mint policy validates owner Schnorr proof, lock window, references existence of an encryption UTxO, has_nft_strict, perimeter pin, owner signature | mint policy (on-chain) | none (I-04 binding gap is a related but separate concern at the proof level) |
+| ReferenceDatum content (`encryption`, `bid`, `groth`, `snark_vk`) | Operator-published at genesis | NO — `genesis.ak` validates only `reference == reference_hash` | operator (off-chain) | I-03 |
+
+The encryption and bid creation paths are fully on-chain-enforced. The genesis creation path is on-chain-enforced for the `reference_hash` field only; the rest is operator-trusted. I-03 captures this. No other off-chain-only enforcement paths exist in the target.
+
+## 12. Mint ↔ Spend Coupling Matrix
+
+| Policy | Asset | Action | Spend Validator | Redeemer | Coupling Enforcement |
+| --- | --- | --- | --- | --- | --- |
+| genesis | `(genesis_pid, genesis_tkn)` | mint | reference.ak (always-fail) | n/a — UTxO never spends | one-shot via `(tx_id, tx_idx)` parameter; `reference == reference_hash` checked |
+| encryption | `(encryption_pid, fresh_tkn)` | mint via `EntryEncryptionMint` | encryption.ak (own mint validator) | n/a (mint) | self-coupling — mint validator is the same script |
+| encryption | `(encryption_pid, fresh_tkn)` | burn via `LeaveEncryptionBurn(tkn)` | encryption.ak (own spend validator) | `RemoveEncryption` | mint side enforces `[(pid, tkn, -1)]`; spend side enforces `no_output_holds_token` + owner signature |
+| bidding | `(bidding_pid, fresh_tkn)` | mint via `EntryBidMint` | bidding.ak (own mint validator) | n/a (mint) | self-coupling |
+| bidding | `(bidding_pid, fresh_tkn)` | burn via `LeaveBidBurn(tkn)` | bidding.ak (own spend validator) | `RemoveBid` (with owner sig + lock expired) OR `UseBid` (paired with encryption.UseEncryption) | mint side enforces `[(pid, tkn, -1)]`; spend RemoveBid enforces burn + owner; spend UseBid enforces burn + encryption-input-coupling |
+
+All mint/burn paths are coupled with the corresponding spend validator. No free-mint paths exist (every mint requires a fresh seed UTxO and burns require the spend validator's specific terminal redeemer).
+
+## 13. Replay / Off-Chain Signature Analysis
+
+**No `verify_ed25519_signature` calls anywhere in the target.** The protocol does not use Cardano-key cheques. Off-chain signatures are not part of the design.
+
+The cryptographic proofs that ARE used (Schnorr knowledge, binding sigma, Wang pairing, Groth16) are reviewed in §5g of the working notes and findings I-04 (Schnorr binding gap) and §3.7 Out-of-Scope (cryptographic primitive correctness).
+
+## 14. Cross-Validator Coherence
+
+| Pair | Coupling | Enforced? |
+| --- | --- | --- |
+| genesis mint ↔ reference UTxO | mint asserts `reference == reference_hash` and output goes to `address.from_script(reference)` | yes (on-chain, M-01 prior fix) |
+| encryption.UseSnark ↔ groth.withdraw | spend reads `groth_script` from ReferenceDatum, searches for the withdraw redeemer with `for_withdraw_redeemer_by_script_hash`, expects `GrothWitnessRedeemer`, builds `expected_output_datum_data` with the withdraw redeemer's `(groth_proof, groth_public, ttl)`, and asserts `output_datum_data == expected_output_datum_data` — proof is bound between withdraw and spend | yes (on-chain) |
+| encryption.UseEncryption ↔ bidding.UseBid | spend reads `bid` from ReferenceDatum, locates bid input by `selected_bid_token`, asserts `spend_redeemer == UseBid`; bidding.UseBid in turn asserts the encryption input is present with the matching token, `selected_bid_token == pointer`, and burns the bid token | yes (on-chain, bidirectional) |
+| bidding.EntryBidMint ↔ encryption UTxO existence | mint reads `encryption` from ReferenceDatum, requires a reference input with the encryption-token being bid on | yes (on-chain) |
+| genesis ReferenceDatum content (`encryption`/`bid`/`groth`/`snark_vk`) ↔ runtime use | on-chain genesis check enforces only `reference == reference_hash`; the other fields are operator-set and used at runtime without re-verification | **off-chain only** → I-03 |
+
+All cross-validator couplings are firing-coordinated and bidirectional with the single exception captured by I-03.
+
+## 15. Oracle Authentication & Freshness
+
+**Not applicable.** The protocol consumes no external oracle data. The only "oracle-shaped" reference input is the genesis UTxO, which carries the `ReferenceDatum` and is authenticated by the one-shot genesis NFT `(genesis_pid, genesis_tkn)`. There is no time-sensitive oracle, so freshness against `validity_range` is also N/A.
+
+The validity-range usage in the protocol is for time-locks, not oracle freshness:
+
+- `encryption.UseSnark` bounds interval width to ≤1h and asserts `ttl ∈ [ub + 6h, 2*(ub + 6h)]`.
+- `encryption.CancelEncryption` permissionless branch requires `lb > ttl`.
+- `bidding.EntryBidMint` requires `locked_until >= ub + 6h`.
+- `bidding.spend.RemoveBid` requires `lb > locked_until`.
+
+Each use is appropriate for its semantic (upper bound for "earliest the action can affect future state"; lower bound for "earliest the action can occur").
+
+## 16. Optimization Review
+
+**Baseline benchmarks exist? Partial** — 5 `bench` blocks in [lib/benchmarks/](../../contracts/peace-protocol/lib/benchmarks/), three of which are stand-ins (I-05). Realistic-context benches for the encryption/bidding redeemers are absent (see I-01 checklist).
+
+| ID | Optimization | Component | Expected Benefit | Risk | File:Line |
+| --- | --- | --- | --- | --- | --- |
+| O-01 | Replace `search.for_*` linear scans with redeemer-supplied indices (utxo_indexer pattern) | encryption.spend, bidding.spend | drop dominant scans from O(N) to O(1); CPU reduction proportional to N | medium — refactor every spend handler; off-by-one risk; no baseline (benchmark before/after required) | [lib/search.ak:32-135](../../contracts/peace-protocol/lib/search.ak#L32-L135) |
+| O-02 | Dedupe `add_commitments` / `sum_commitments_acc` | lib/types/groth.ak | ~50-100 bytes script-size | low — mechanical refactor; no baseline | [lib/types/groth.ak:125-150](../../contracts/peace-protocol/lib/types/groth.ak#L125-L150) |
+| O-03 | Replace bench stand-ins with real-Transaction fixtures (pairs with I-05) | lib/benchmarks | honest baselines for subsequent optimization claims | low — fixture rewrites; no baseline | [lib/benchmarks/groth.ak:40-53](../../contracts/peace-protocol/lib/benchmarks/groth.ak#L40-L53), [lib/benchmarks/util.ak:82-91](../../contracts/peace-protocol/lib/benchmarks/util.ak#L82-L91) |
+
+Detailed findings: see O-01, O-02, O-03 in §8.
+
+**Stdlib red-flag scan:** `assets.flatten` is used in burn handlers ([encryption.ak:94](../../contracts/peace-protocol/validators/encryption.ak#L94), [bidding.ak:91](../../contracts/peace-protocol/validators/bidding.ak#L91)) pinned to `[(pid, tkn, -1)]` — bounded use, acceptable. `assets.without_lovelace` is used in UpdatePrice paths — bounded use. No `list.sort`, `list.count`, `dict.from_pairs`, `list.flat_map`, `list.zip`, or `list.reverse` in the validator code.
+
+**Aiken optimization patterns applied:** `const` for compile-time fixture data (`wang_h0..h3`, domain tags) — present. Fail-fast `expect` patterns — present. `Data` equality on full datum — present. Tail recursion — present (`derive_vk_x_combined`, `sum_commitments_acc`, `add_commitments`). Witness-verify pattern (`limb_compression` is the canonical "compute off-chain, verify on-chain" lift) — present. Ledger-invariant leverage — yes (no defensive re-checks of min-ADA, mint-ADA-zero, output-quantity-nonneg).
+
+## 17. Test Coverage Review
+
+**Mainnet-readiness:** Mainnet-ready (see §6 rubric). Critical=0, High=0; all five new findings are Informational with the bench/test coverage gaps tracked as actionable backlogs.
+
+| Test Area | Present? | Notes |
+| --- | --- | --- |
+| Happy-path for each redeemer | No | helper layer is exhaustive; validator layer is empty |
+| Negative tests per critical check | Partial | M-03 over-supply negative; helper-level H-01 stake variants; schnorr & binding negative tests; register validation negatives |
+| Property/fuzz tests over Value/Datum | No | `fuzz.constant` is used in benches but no property assertions |
+| Double-satisfaction tx shapes | No | UseBid singleton is enforced in code; no negative tx-shape test |
+| Datum mutation | No | `..this_datum` spread pattern relies on the structural equality check; no fuzz |
+| Redeemer mutation | No | |
+| Wrong-signer | No | |
+| Duplicate inputs/outputs | No | UseBid singleton is in production; no negative test that proves the rejection |
+| Wrong-asset / extra-mint | Partial | search tests cover "extra token in value" via `has_nft_strict` rejection |
+| Burn tests for terminal redeemers | No | LeaveEncryptionBurn / LeaveBidBurn behaviour untested directly |
+| Validity-interval edge cases (Always, Inf) | No | UseSnark / CancelEncryption / EntryBidMint / RemoveBid bound checks untested |
+| Reference-input mutation | No | `for_reference_datum` requires the genesis NFT but the validator-level chain isn't tested |
+| Continuing-output stake-cred mutation | Partial (helper level only) | `util.is_protocol_output` regression suite covers four stake variants; the validators inline the same checks and aren't driven adversarially |
+| Continuing-output reference-script attached | Partial (helper level only) | same as above |
+| Benchmarks for hot paths | Partial | 5 benches; three are stand-ins (I-05); 13 of 15 redeemer constructors uncovered (I-01) |
+| Worst-case datum-size benchmark | No | no large-datum bench (e.g., Pending status with `GrothPublic = List<Int>` at the deployed snark_vk's `nPublic - 1` length) |
+
+**Per-redeemer-constructor coverage**
+
+| Validator | Redeemer Constructor | Happy? | Negative? | Property? | Bench? |
+| --- | --- | --- | --- | --- | --- |
+| genesis.mint | (Data, unused) | No | No | No | Partial (stand-in I-05) |
+| reference.spend | else(_) fail | n/a | n/a | n/a | n/a |
+| encryption.mint | EntryEncryptionMint | No | No | No | No |
+| encryption.mint | LeaveEncryptionBurn | No | No | No | No |
+| encryption.spend | RemoveEncryption | No | No | No | No |
+| encryption.spend | UseEncryption | No | No | No | No |
+| encryption.spend | UseSnark | No | No | No | No |
+| encryption.spend | CancelEncryption | No | No | No | No |
+| encryption.spend | UpdateEncryptionPrice | No | No | No | No |
+| bidding.mint | EntryBidMint | No | No | No | No |
+| bidding.mint | LeaveBidBurn | No | No | No | No |
+| bidding.spend | RemoveBid | No | No | No | No |
+| bidding.spend | UseBid | No | No | No | No |
+| bidding.spend | UpdateBidPrice | No | No | No | No |
+| groth.withdraw | GrothWitnessRedeemer | Yes (`valid_groth_proof1/2`) | Yes (`fail_groth_proof1_public_oversupplied`, `verify_commitments_invalid_pok`) | No | Yes (`groth__withdraw__verify_groth16_low_n`, `_high_n` (stand-in)) |
+| groth.publish | Register(ScriptHash) | No | No | No | Partial (stand-in I-05) |
+
+**Test-Fixture Variance**
+
+| Fixture Field | Default | Variants Tested | Verdict |
+| --- | --- | --- | --- |
+| Address.stake_credential | None | None / Inline(VerificationKey) / Inline(Script) / Pointer | full helper-level coverage; no validator-level fixture |
+| Output.reference_script | None | None / Some(_) | partial (helper-level only) |
+| tx.mint | n/a (helpers don't read it) | n/a | n/a at helper level; validator-level negative tests must add adversarial mint variants — folded into I-02 |
+| tx.certificates | n/a | n/a | groth.publish would need Conway cert variants; absent — folded into I-02 |
+| tx.validity_range | n/a | n/a | UseSnark / CancelEncryption / EntryBidMint / RemoveBid need adversarial bound variants — folded into I-02 |
+| Output.value default shape | Lovelace-only or Lovelace + 1 NFT | (search.ak: one extra-token variant) | partial; multi-asset shapes untested — folded into I-02 |
+
+**Test Smells Found**
+
+- Only happy paths: not quite — the helper-layer suite has rich negatives, but the validator layer has neither happy nor negative tests.
+- Tests that re-import production code rather than driving via Transaction: yes — all current tests are at the helper layer (calling production helpers directly, not the validator). Folded into I-02.
+- Absurdly small synthetic contexts: yes for the benches (1 input, 1 output, 0 ref inputs) — `lib/benchmarks/util.ak`'s fixtures are minimal. Folded into I-01 / I-05.
+- Missing `fail` keyword on expected-failure tests: not present — every `test fail__*` / `_fails_*` carries the `fail` keyword. ✓
+- Hardcoded test data not reflecting Cardano realities (no min-ADA, unrealistic native-asset counts): yes — bench fixtures use `from_lovelace(2)` everywhere; no native-asset variants. Folded into I-01.
+
+## 18. Off-Chain Builder Review
+
+**Not applicable** — no TypeScript / Lucid / Mesh / Blaze transaction-builder code is present in TARGET_CONTRACT_FOLDER. The only off-chain artefact is [compile.sh](../../contracts/peace-protocol/compile.sh), which is a deployment-time bash + python build script (not a transaction builder). `compile.sh` is reviewed at the bash/python level for I-08 token-name parity (the off-chain construction of `bytes([tx_idx]) + tx_id` truncated to 32 bytes matches the on-chain `util.construct_token_name`).
+
+The README references `app/commands/` and `app/setup.sh` as off-chain deployment scripts, but those files are not present in the target. They are out of scope per §3.7.
+
+**Is the validator safe if a malicious user bypasses the official builder?** Yes — restated from §3.8: every continuing-output / input-filter / NFT-strictness / signer-verification check is enforced on-chain. The H-01 perimeter pin is inlined at every site. No off-chain enforcer is load-bearing for the protocol's spend-time security. The one residual off-chain trust point is operator-set `ReferenceDatum.snark_vk` at bootstrap (I-03), which is a deploy-time concern not a runtime tx-builder concern.
+
+## 19. Dead Ends / Non-Issues / False Positives
+

+| Absent ADA min-check on continuing outputs | not a finding | ledger enforces min-ADA per output | n/a — ledger invariant |

+| Withdraw amount checks (zero-withdrawal trick) on `groth.withdraw` | not a finding | `groth.withdraw` is a Groth16 verifier triggered via the zero-withdrawal pattern; this is the standard idiom for "validator-as-witness" and the script does not gate funds | [validators/groth.ak:15-34](../../contracts/peace-protocol/validators/groth.ak#L15-L34) |
+| `groth.publish` only accepts `RegisterCredential` (deregister forever blocked) | not a finding | design decision — once the credential is registered, the verifier is permanently available; the 2-ADA registration deposit is the price of having the verifier on-chain | [validators/groth.ak:36-47](../../contracts/peace-protocol/validators/groth.ak#L36-L47) |

+## 20. Final Recommendations
+
+### 20.0 Coordinated Fixes
+
+| Root Cause Slug | Findings | Proposed Single Fix | Effort | Risk |
+| --- | --- | --- | --- | --- |
+| `bench-fixture-stand-in` | I-05, O-03 | Refresh the three stand-in benches (`groth__withdraw__verify_groth16_high_n`, `groth__publish__register_credential`, `genesis__mint__one_shot_bootstrap`) to use real-Transaction fixtures + a larger `nPublic` SnarkVerificationKey. This single fixture pass closes both the coverage-quality view (I-05) and the optimization-backlog view (O-03). | ~3 hours; one new fixture module + edits to two bench files | Low (mechanical; benches are not on-chain code) |
+
+No other shared root-cause slugs. The remaining findings (I-01, I-02, I-03, I-04, O-01, O-02) each have a distinct root cause.
+
+### Must Fix Before Mainnet
+
+None. The protocol has no Critical, High, Medium, or Low security defects. All findings are Informational or Optimization.
+
+### Should Fix Before Mainnet
+
+1. **I-02** — Add validator-level happy-path and negative tests. The H-01 perimeter fix's regression-resilience depends on this; the existing helper-layer suite is not sufficient. Effort: ~1-2 days of fixture and test authoring. This is the single most impactful improvement to long-term maintainability.
+2. **I-03** — Commit the bootstrap trust model to spec. Add an explicit "Trust Model" section to README. Optionally bake `snark_vk_hash` into the genesis policy parameters for belt-and-suspenders. Effort: ~2 hours docs; ~1 day for the optional code change + re-tests.
+
+### Nice To Have
+
+1. **I-01** — Fill the bench coverage gap per the checklist. Effort: ~1 day. Necessary precondition for the O-01 optimization measurement.
+2. **I-04** — Make and document the `(owner_vkh, owner_g1)` coupling decision. If binding: thread `owner_vkh` into the Schnorr FS preimage and add the negative tests. If not binding: document the intentional looseness and the bid-spam concern. Effort: ~2 hours docs; ~3 hours if implementing the binding.
+3. **I-05 / O-03** — see §20.0 Coordinated Fixes.
+
+### Optimization Backlog
+
+1. **O-01** — `utxo_indexer` pattern adoption. Conditional on I-01 (benches) being in place to quantify the delta. Effort: ~1-2 days refactor.
+2. **O-02** — Dedupe `add_commitments` / `sum_commitments_acc`. Effort: ~10 minutes.
+3. **O-03** — see §20.0.
+
+### Documentation Backlog
+
+1. **Trust Model section in README** (per I-03 fix path 1) — explicit statement that `ReferenceDatum.snark_vk` and three of four script-hash fields are operator-trusted at bootstrap; what observers should verify post-deployment.
+2. **`(owner_vkh, owner_g1)` coupling policy** (per I-04) — document whether the two must derive from the same principal.
+3. **Inline doc-strings** on `schnorr.verify` and `schnorr.binding_verify` clarifying what each proof binds and does not bind.
+4. **`bench` README** explaining the rationale for each bench's scenario (low_n / mid_n / high_n) and noting which are stand-ins pending I-05 fix.

+# Smart Contract Audits
+
+Each audit is authored by an AI model and should be read as a supplement to — not a replacement for — human cryptographic and economic review. Over time, as newer models come online, additional audits are added here so findings can be compared across audit dates.
