Summary

Record and reproduce @haot3x's scoped independent wallet client against official ERC-8350 reference source at 8b11215cf267f710b49ea003384e678bcf953eae.

• Pin haot3x/agent-economy-contributions@b4ba24169e63ede14eb2f11f8115ff058845aa55, relevant file SHA-256 values, exact scenario names and build digest.
• Run the unchanged external client from a fresh detached checkout with an isolated environment and pinned toolchain. Verify 34 scenarios plus one historical-decoder negative control, and 188 mined receipts (131 success, 57 expected reverts).
• Archive native reports, logs, commands, local block range and artifact hashes. Preserve the initial maintainer-wrapper failure: ethers Receipt.toJSON() omits type; the fixed validator uses the unchanged pinned executable's explicit type-4 assertion and required named outcome instead of inventing a report field.
• Add fail-closed validator tests and a read-only CI workflow; map coverage into the authorization and Draft-to-Review packets.

Scope and limitations

This is independent client execution against the official reference, not an independent Registry implementation, full #21 acceptance, an audit, or production certification. Safe is pinned to 1.4.1; local Anvil/Prague execution does not imply Sepolia/mainnet or arbitrary wallet-version coverage. Historical Python evidence keeps its original pins. Issue #21 remains open.

Official ethereum/ERCs#2151 was author-approved and merged as 47c7f884; that NatSpec-only correction is documented without relabelling these source-pinned runs as tests of the newer commit. No core runtime, signing input or baseline manifest is changed here.

Verification

• Local gate: clean consumer checkout, clean external source before/after, exact official-source SHA-256 checks, Node 24.11.0 / npm 11.6.1 / Foundry 1.7.1 / Solidity 0.8.24.
• node --test scripts/independent-wallet-gate.test.mjs scripts/independent-client-gate.test.mjs scripts/spec-baseline.test.mjs scripts/review-candidate.test.mjs: 78 passing, zero skipped.
• The native successful record and preserved initial wrapper failure are linked in docs/interop/independent-wallet-results.md.
• GitHub CI status is reported by the checks on this PR, not inferred from local success.

Related: project #21; official ethereum/ERCs#2148 and ethereum/ERCs#2151.

Verification completed at head 5e659ab647bd001c394c57e93aefde00531e1e83:

• All 10 active checks passed; the conditional failure-notification job was skipped as expected.
• Fresh Linux wallet gate passed 35/35 with the same 188 receipts and local block range 4–196 as the archived macOS reproduction. I downloaded its native artifact and verified all 16 artifact SHA-256 values; CI consumer commit is the synthetic PR merge 8b05fa5fbd3ceeeed7e597983ef649bf698f7af2, not a main merge.
• Clean-checkout conformance, TypeScript and Solidity, exact source checks, maintainer account suite, and existing independent Python client passed.
• After verification, updated issue #21 and supplied official #2148 review material.
• Official #2151 is merged, but this project PR remains open. The published evidence links use the immutable PR head and do not claim a main merge, full independent Registry, external audit acceptance or Review status.

[haot3x]

Reviewed the wallet evidence at 5e659ab. All 11 file hashes and 35 named outcomes match my pinned client/run; the 16 gate tests pass locally. The scope and receipt-type caveat are accurate. Approved for this evidence/CI change.
