# Frozen Handoff for Independent Human Audit

## Handoff purpose

Give an independent human smart-contract reviewer a reproducible, bounded source package for the exact proposed Base V3 read-only bootstrap. This handoff is not an audit report, audit engagement, finding closure, production-readiness conclusion, or guarantee that the source is bug-free.

| Included production source | All 28 tracked files under `v3-src/contracts`, including the six read-only bootstrap contracts and the two internal specialized bond factories created by `SafeBondFactoryV3` |
| Included dependencies | `forge-std` `680ee6692649dcc7c617e05b2144932618264a83`; OpenZeppelin `dbb6104ce834628e473d2173bbc9d47f81a9eec3`; nested dependencies are recorded by `git submodule status --recursive` |
| Excluded deployment scope | Child bonds, escrow, vaults, pools, x402 routes, Bazaar listings, payees, design partners, modules, attesters, adjudicators, value transfers, activation calls, and public writes |
| Compiler and EVM settings | Solidity `0.8.24`, optimizer and via-IR settings from `v3-src/foundry.toml` whose SHA-256 is `ab1bd18ace9d62481412c972d05cd12e3ea428fc4a7cffdd6c274844cf8a9da5` |
| Foundry tooling | Forge and Anvil `1.7.1`, commit `4072e48705af9d93e3c0f6e29e93b5e9a40caed8` |
| Reproducible build | Canonical release gate passed for 46 deployable creation/runtime pairs; prior RC2 independently clean build evidence covers 43 deployable artifacts within EIP-170/EIP-3860 limits |
| Full Solidity execution | 39 non-fork paths, 136 passed, 0 failed, 0 skipped; 1,000 fuzz runs and 64 invariant runs with a fixed recorded seed |
| Base fork execution | Base chain `8453`, block `50317469`, hash `0x1ac7b7f5babf746191014dc402029642f35dce55d7ed4b24d5c837bc98e02055`; 6 tests passed, 0 failed, 0 skipped across availability, deployment/rollback, and stale-term regression runs |
| Static analysis | Complete repository Slither policy passed with 46 contracts, 60 detectors, and zero non-baselined findings |
| Bootstrap tooling | 17 Python tests passed; isolated 20-source Base read-only bootstrap gate passed with `pilotReady=false` |
| V2 compatibility | Strict ABI gate verifies 36 provenance-backed deployed contract names; 134 frozen V2 runtime hashes verified; PR7 has 60 tests passing and preserves V2 as default |
| V2 ABI recovery | Public alias `VaultfireTrustAttestation` is bound to exact source contract `TrustPortabilityExtension`, Solidity `0.8.25`, and identical 12,259-byte deployed runtime evidence on Base, Avalanche, Arbitrum, and Polygon |
| x402 status | Security regressions pass locally, but live V3 settlement, durable production concurrency/idempotency, owner Bazaar evidence, and a funded canary remain unverified and out of this bootstrap deployment |
| Solana status | Source-only and `not_deployed`; no native Anchor/SBF/validator build is claimed and Solana is not a prerequisite for the Base read-only bootstrap |
| Deployment package | Not generated. The checked-in profile is intentionally blank and non-deployable until five signers, one distinct guardian, one distinct treasury, custody disclosures, deployer address, and nonce are supplied |
| Audit status | **Exact-commit AI-assisted adversarial review** evidence exists for the commit it names. Independent human audit completion remains `false`; no audit or mainnet-readiness claim is permitted. |

## Required review questions

1. Does the exact frozen source produce the recorded creation and runtime bytecode under the pinned toolchain?
2. Do `MultisigGovernanceV3`, `BasePilotAccessControllerV3`, and `SafeBondFactoryV3` enforce 3-of-5 governance, the immutable 86,400-second minimum timelock, bounded guardian powers, and default-closed deployment/write/value behavior?
3. Can any constructor, internal factory creation, forced Ether, callback, reentrancy, signature replay, stale authorization, or accounting path make the read-only bootstrap value-bearing or pilot-ready?
4. Are mutual consent, immutable or consent-controlled terms, mandate/provenance binding, caps, liabilities, pull withdrawals, disputes, expiry, cancellation, and pause-preserved recovery correctly enforced in both specialized bond implementations?
5. Are V2 withdrawals, routes, ABIs, APIs, SDK behavior, and V2-default version selection preserved without implicit V3 redirect or V3-to-V2 money fallback?
6. Are all evidence and identity paths data-minimized, and are flourishing metrics non-slashable and unable to authorize confiscation?
7. Is every accepted High or Medium finding remediated in the exact frozen source with an exploit-oriented regression?

## Reviewer deliverables

Return scope confirmation, commit and archive hash, tooling version, independent reproducibility result, findings with severity and evidence, remediation disposition, unresolved assumptions, and an explicit statement of what was not reviewed. The final report must name the exact source commit and must not be paraphrased as approval beyond its stated scope.

## Remaining human gates

The Accountability typed-enforcement correction post-dates the frozen commit
above. The archive hashes and test counts above do not cover that correction.
A replacement freeze must name its exact commit and repeat every applicable
gate; until then, only the phrase **exact-commit AI-assisted adversarial
review** may describe the current review state.

1. An independent human smart-contract auditor must accept this exact scope, complete the review, and disposition every finding.
2. The owner must supply and verify exactly five Base governance signer addresses, a distinct guardian, a distinct treasury, and truthful signer custody disclosures.
3. The owner must supply an existing public deployer address and fresh contiguous nonce for deterministic address derivation.
4. After the unsigned six-transaction package is independently re-encoded and reviewed, deployment still requires the exact phrase `APPROVE BASE V3 READ-ONLY DEPLOYMENT`.
5. Partner activation is a separate later gate requiring the independent audit, real roles and consent, approved caps, live payment evidence, and `APPROVE CAPPED BASE V3 PARTNER PILOT`.
