# Vaultfire V3 — Final Readiness Report

- **Report date:** 2026-08-21
- **Integrated review commit:** `468fe16c02252622790c96cbce8071d6573f0e63`
- **Branch:** `feat/v3-prompt-completion-integration`
- **Scope:** additive V3 contracts; V2 compatibility; x402/Bazaar metadata;
  migration, pilot, governance, and website-readiness artifacts.

## 1. Readiness decision

**Vaultfire V3 is not pilot-ready and is not mainnet-ready.**

The current implementation and verification checkpoint materially improve the
review package, including contract-enforced native bond liability caps and a
successful official Base-mainnet fork simulation. They do not authorize a
deployment, pilot, or public write path. The checked-in deployment manifest
continues to have no V3 addresses and unset owner roles; the pilot gate reports
`pilotReady: false`. The owner-selected tiny native-cap profile is now recorded,
but it has not been independently audited or verified against a deployment.

No independent audit has been completed. No owner-provided live Bazaar
validation, settlement, or indexing evidence is present. No transaction,
signature, deployment, treasury change, or production configuration change is
part of this documentation update.

## 2. V2 baseline and compatibility status

| Item | Current result | Evidence / implementation |
| --- | --- | --- |
| Frozen V2 runtime bytecode | 134 manifest hashes remain checked in | `ci/manifests/v2-bytecode-manifest.json`; `ci/check_v2_bytecode_manifest.py` |
| ABI provenance | 35 of 36 deployed V2 names have provenance-backed ABIs | `baseline/V2_ABI_PROVENANCE.md`; `legacy/v2/manifest.json` |
| ABI release blocker | `VaultfireTrustAttestation` still lacks an authoritative exact ABI; strict validation deliberately fails | `baseline/V2_ABI_FOLLOWUP_REPORT.md`; `baseline/check_v2_abi_package.py --strict` |
| Response fixtures | 1 exact route fixture; 131 V2 response fixtures remain explicitly unresolved | `baseline/schemas/v2/route-response-fixtures.json` |
| Route-method alignment | 132 of 132 extracted V2 paths are now represented in the registry; 50 extracted paths are method-only rather than fully operationally described | `pr7/generated/v2-inventory-alignment.json`; `baseline/schemas/v2/route-source-method-evidence.json` |

The V2 ABI package must still be described as **35/36 provenance coverage**, not
complete ABI coverage. The V2 route-method result must likewise not be
overstated: 132/132 alignment eliminates the prior untyped-path gap, but it
does not resolve the 131 absent response captures.

## 3. V3 contract implementation and cap enforcement

V3 remains additive under `v3-src/contracts/`: mandate/signature and identity
components, bonds, rewards, pull payments, evidence/dispute and reputation,
escrow, mutual aid, ERC-4626 vault, governance, and the Base pilot controller.
No V2 deployment is upgraded or replaced.

The partnership and accountability bonds are now native-only and enforce
immutable constructor-supplied wei caps in contract:

| Contract family | Enforced native limits |
| --- | --- |
| `PartnershipBondV3Safe` | Per-party, per-bond, and aggregate principal/liability caps. |
| `AccountabilityBondV3Safe` | Per-bond and aggregate principal/liability caps. |
| Both | Zero caps are rejected; aggregate capacity remains occupied through settlement/refund crediting and releases only after successful pull-payment withdrawal. |

The implementation and focused coverage are in
`PartnershipBondV3Safe.sol`, `AccountabilityBondV3Safe.sol`,
`SafeBondFactoryV3.sol`, the specialized factories, and
`v3-src/test/bonds/BondNativeCapsV3.t.sol`. The caps are real contract
constraints. The owner-selected tiny Base profile is recorded as partnership
`0.01 ETH` per party, `0.02 ETH` per bond, and `0.20 ETH` aggregate, plus
accountability `0.02 ETH` per bond and `0.20 ETH` aggregate. These values still
require independent review and deployment verification. The checked-in review
manifest cannot produce a production payload while owner roles, audit evidence,
approval, and verified deployment addresses remain absent.

## 4. Current verification checkpoint

The following exact results apply to the current integrated checkpoint:

| Verification | Result |
| --- | --- |
| Foundry RPC-free suite | **121 tests passed**. |
| Fork availability checks | **4 tests passed**: Base executed against `https://mainnet.base.org`; Avalanche, Arbitrum, and Polygon were explicit skips because their RPCs were not supplied. |
| Base deployment/rollback simulation | **1 test passed** on the official Base-mainnet fork. It is an ephemeral, non-broadcasting Foundry fork simulation. |
| PR7 API/SDK/indexer/x402/Bazaar package | **46/46 tests passed**. |
| PR9 website version-gate package | **36/36 tests passed**. |
| Manifest/payload package | **17/17 tests passed**. |
| Slither | **Zero non-baselined findings.** |
| Clean deterministic build checkpoint | Checkpoints **A** and **B** each produced **123 artifacts**; their exact creation/runtime bytecode manifests are equal. |
| Production runtime sizes | Partnership **18,396 B**; Accountability **16,929 B**; SafeBondFactory **1,561 B**. |

The fork result is real Base fork evidence, unlike the former local chain-ID
8453 emulator-only smoke result. It is still not a deployment: the test does
not broadcast, read a private key, or alter Base state. The three missing
non-Base RPCs are recorded skips, not passed multi-chain fork validations.

Historical files in `release-evidence/` document earlier checkpoints. They must
not be used to replace the current 121-test, 123-artifact, or current-size
results above.

## 5. Current x402 and Coinbase Bazaar state

The current generated registry contains **147 routes**: **143 V2** and **4
V3**. Its V2 inventory alignment is **132/132**. There are **77 Bazaar
metadata candidates**, **0 statically blocked candidates**, and **29 Solana
payment options**. The static package uses Bazaar resource version `v2` and
x402 payment rail version `2`.

**Three distinct dimensions must remain separate:**

1. **Vaultfire contracts V3** is the additive Solidity implementation. It has
   no verified public V3 addresses.
2. **Bazaar resource metadata v2** describes the generated discovery resource
   format.
3. **x402 payment rail v2** describes payment metadata and validation format.

Static candidate completeness is not live readiness. The checked-in
`bazaar-readiness.json` declares
`metadata-candidates-not-live-validated`. The fail-closed owner gate still
requires, for every candidate, owner-supplied public x402-v2/402 validation and
accepted preflights; it also requires at least one separately authorized,
successful settled payment bound to a resource plus a non-rejected Bazaar
extension response. There is no committed owner/live Bazaar evidence and no
claim of publication, validation, settlement, or indexing.

The V3 protocol-status and solvency surfaces remain fail-closed: with no live
V3 deployment/read-plan inputs they report degraded status rather than a
plausible healthy default.

### Solana readiness and partner-led activation

The checked-in Solana handoff is explicitly source-only. It does **not** claim a
Vaultfire V3 program is deployed on Solana mainnet: no program ID, deployment
transaction, reproducible deployed-bytecode comparison, independent audit, or
upgrade-authority custody record is available. `MAINNET_READINESS.json` records
this as `not_deployed` and the partner path as `not_ready`.

The PR7 registry retains **29** canonical Solana payment options marked
`settlement-configured`; that is checked-in x402 USDC source metadata, not a
published discovery capture, facilitator confirmation, or settled payment.
Before any partner-led activation, obtain a payee-ownership attestation, mint
provenance review, controlled mainnet settlement receipt, route challenge and
receipt capture, plus replay/expiry/incident-handling evidence. The eight
listed Solana trust/indexing lanes remain passive/read or receive-only inventory
until independent RPC, webhook, indexer, and production-route evidence is
recorded.

A partner-led native program remains optional and blocked pending a written
partner approval and accountable signatory, independent audit and remediation
disposition, verifiable program ID and deployment transaction, reproducible
build/deployed-bytecode comparison, upgrade-authority/emergency plan, and
accepted monitoring, webhook, indexer, and rollback controls. No Solana V3
program deployment is authorized or implied by this source tree.

## 6. Migration, manifest, and rollback posture

Migration remains voluntary and defaults to V2. The migration UI is
simulation-only: it has no signer, wallet writer, RPC write, or broadcast
path. The deterministic proposal/payload tooling is offline and unsigned; it
generates governance-proposal transport rather than authorizing direct calls to
owned modules.

The current review manifest is intentionally non-executable:

- every V3 deployment address is `null`;
- five tiny native-bond cap values are selected in the review manifest, but they
  are not verified against a deployment and remain subject to independent review;
- governance signer, guardian, treasury, attester, adjudicator, design-partner,
  and on-chain owner roles are unset;
- `--for-payload` validation fails until roles, independent audit evidence,
  verified addresses, and explicit approval are supplied.

Rollback remains additive: pause V3 through the finalized
governance/guardian path, disable V3 API/UI entry points, and leave V2
contracts, routes, and positions unaffected. Pull-payment exits remain part of
the contract and rollback design.

## 7. Fork, deployment, address, and website status

`ci/fork-gates.sh` now has a successful official Base-mainnet run as described
in section 4. The Base deployment/rollback test validates constructor ordering,
final governance bindings, default-closed controller behavior, caps and
allowlists, timelocked rollback, pull-payment withdrawal after pause, and
read-only V2 witnesses. This is a high-value pre-deployment control-flow check,
not proof of a deployed V3 system.

No V3 address belongs in `baseline/deployments.json` or the review manifest at
this stage. The website's default-off V3 gate must therefore continue to
return `v3-deployment-address-missing`; protocol status stays degraded and
money movement stays disabled. PR9's 36 passing package tests do not establish
production website wiring: the production source remains a gitignored vendored
mirror and is not wired or deployed by this tree.

## 8. Centralized dependencies and remaining external blockers

| Area | Current blocker |
| --- | --- |
| Governance and roles | Final multisig signers, separate guardian, treasury, attesters, adjudicators, design partners, pilot modules, and on-chain owner address are unset. |
| Cap configuration | Tiny Base profile selected and recorded; independent review and deployed-constructor verification remain absent. |
| Addresses and selectors | There are no verified public V3 deployments or post-deployment selector/role checks. |
| Assurance | No independent audit; bug bounty remains unratified/unproven live. |
| Operations | Monitoring, alert delivery, secondary on-call, rehearsal, indexer operation, and facilitator/RPC failover remain unproven. |
| Bazaar | No owner-provided public validation, settled-resource evidence, accepted Bazaar response, or live-indexing evidence. |
| Solana | No Vaultfire V3 program deployment evidence; 29 x402 USDC options are source metadata only; partner approval, audit, deployment proof, custody plan, and operational receipts are absent. |
| Compatibility | One authoritative V2 ABI is missing and 131 V2 response fixtures remain unresolved. |
| Authorization | No explicit deployment approval exists; `pilotReady` remains false. |

The centralized infrastructure and authority assumptions remain documented in
`pr8/governance/CENTRALIZED_DEPENDENCIES.md`,
`pr8/governance/MULTISIG_TIMELOCK_PLAN.md`,
`pr8/runbooks/MONITORING_RUNBOOK.md`, and `pr8/audit/SECURITY.md`. Those files
are plans and runbooks, not operating proof.

## 9. Reviewed changes and evidence boundary

The current review includes these readiness-relevant commits above the previous
documentation checkpoint:

| Commit | Readiness-relevant change |
| --- | --- |
| `0a69bba` | Frozen source-backed V2 route-method evidence and 132/132 registry alignment. |
| `5e08b34`, `357cdd0` | Bazaar v2 metadata hardening and source-backed input-schema recovery; 77 candidates, zero static blockers. |
| `fcdc962` | Base fork gate EOA fixture correction. |
| `b7577b9` | Fail-closed pilot manifest and unsigned governance-payload hardening. |
| `c3cd46a` | Replaced legacy solvency invariant coverage. |
| `bc18934` | Routed pilot administration through multisig proposals. |
| `468fe16` | Enforced immutable native bond caps and aggregate liability accounting. |
| `fdddcbb` (integrated as `b5b9b0b`) | Added the fail-closed Solana partner-led mainnet handoff; its PR7 assertion was reconciled to the newer 29-option source metadata without a settlement or deployment claim. |

The current checkpoint results in section 4 are the applicable verification
statement for `468fe16`. The older `release-evidence/` receipts remain retained
as historical artifacts, but they describe earlier source checkpoints and are
not represented here as current-release evidence. Their current file digests
are recorded for traceability only:

## 10. Exact readiness checklists

### Before audit handoff

- [ ] Freeze an audit target commit and attach the current 121-test,
      Base-fork, 123-artifact checkpoint, static-analysis, PR7, PR9, and
      manifest/payload records.
- [ ] Give the auditor the native-cap implementation, aggregate-liability
      release behavior, constructor/bootstrap plan, all V3 source, and the
      migration/governance artifacts.
- [ ] Disclose the unresolved `VaultfireTrustAttestation` ABI and 131
      unresolved V2 response fixtures; do not call either area complete.
- [ ] Disclose the absence of owner/live Bazaar evidence, the Solana
      source-only/partner-led handoff blockers, and all remaining non-Base
      fork-RPC coverage.

### Before any capped pilot

- [ ] Complete the independent audit and resolve all unmitigated High findings.
- [ ] Independently review the five selected positive native-wei cap values and
      confirm they remain appropriate for the named allowlisted design partners;
      keep `party <= bond <= aggregate` for partnership and
      `bond <= aggregate` for accountability.
- [ ] Finalize the 3-of-5 signers, separate guardian, treasury, attesters,
      adjudicators, design partners, pilot modules, and 24-hour governance
      configuration.
- [ ] Obtain explicit approval, deploy only through the approved mechanism,
      and verify addresses, bytecode, constructor caps, ownership, roles,
      selector scan, controller hooks, and configured controller caps.
- [ ] Record real pilot-gate evidence hashes until `pilotReady: true`; the
      checked-in template must stay non-passing until then.
- [ ] Complete monitored staging, alert delivery, incident rehearsal, a
      two-engineer on-call rota, service failover checks, and a live bounty.
- [ ] Provide owner-authorized Bazaar evidence before representing a resource as
      validated, settled, or indexed.

### Before broader mainnet enablement

- [ ] Complete and independently review a capped Base pilot with stable
      operations and post-pilot evidence.
- [ ] Close audit and bounty findings, then review any material remediation.
- [ ] Demonstrate Base and supporting-service failover, monitoring, indexer,
      facilitator, and incident response under rehearsal.
- [ ] Re-verify every V3 address, role, cap, registry, website integration,
      treasury/payee, and final governance proposal.
- [ ] Obtain explicit authorized approval for expansion.
- [ ] For any partner-led Solana activation, complete the separately recorded
      partner approval, audit, deployment, reproducibility, custody, x402
      settlement, and operational-evidence requirements; do not relabel source
      metadata or read-only lanes as a Vaultfire V3 deployment.

Until every applicable item has attributable evidence, no pilot or mainnet
readiness claim is authorized.
