…broadcast logs Application-evidence package for the Circle 2026 Cohort 2 (Arc) grant: - test/fixtures/cctp/arc-to-base-hook-v2.json: the placeholder becomes a REAL capture from the 2026-07-17 live run — the 420-byte Iris message (376 CCTP v2 burn + 44 Lattice hook envelope) and 130-byte attestation for Arc burn 0x45071a…5ac39, relayed on Base in 0xc41fbe…badfc (block 44258756). test_Fork_RelayWithHookCreditsVaultFromRealAttestation now RUNS (was skipping): pinned-fork replay through the live Base diamond credits exactly 1 USDC and the second relay reverts (nonce consumed). - broadcast evidence committed (ENS-M1 precedent): the three real hook- demo multichain setups, the hook relay logs (84532), and the Arc-hub transfer demo logs (setups + relays on 11155111/84532/5042002). The probe-generated multi/-latest and a resume-duplicate dir are excluded. - README: 'Live cross-chain USDC demos' section — both demos, all addresses/txs as explorer links (Sourcify-aware: Base links point at Blockscout), one-command reproduce. - PROGRESS.md: restructured as a per-grant index (ENS section unchanged) plus a 'Circle Arc Grant' evidence table: adapter permalinks, hub / diamond / vault, USDC deliveries to both destinations, the one-tx mint+hook proof with the decoded Credited event, the replayable fixture, and broadcast-log paths.
Per operator direction: the evidence set is the -latest broadcast of each step (ENS-M1 precedent), not the per-run timestamped history — 7 files: hook setup (multi) + hook relay, transfer setup (multi + Arc per-chain) + both destination relays + the legacy Sepolia burn. broadcast/multi/CCTPHookDemo.s.sol-latest is restored from the last real testnet run's timestamped copy (Arc hub 0x3446…, the documented one) — the on-disk file had been overwritten by a local two-anvil probe. .gitignore now excludes timestamped run copies (run-1*.json and multi/*.s.sol-1*) so future demo runs never clutter git status; -latest names never match either pattern.

Circle Arc grant — application evidence package
Everything a reviewer needs to verify the "CCTP + USDC currently integrated" claim, before the video is even played.
The fixture is real now
test/fixtures/cctp/arc-to-base-hook-v2.jsonwas a placeholder since #148; it now holds the captured Iris message + attestation from the 2026-07-17 live run (Arc burn0x45071a…5ac39→ Base relay0xc41fbe…badfc, block 44258756). The message is 420 bytes = 376 (CCTP v2 burn) + 44 (Lattice hook envelope) — the byte math independently confirms the envelope rode inside the attested message.test_Fork_RelayWithHookCreditsVaultFromRealAttestationnow runs green (previously skipped): it forks Base Sepolia one block before the real relay, replays the actual attested bytes through the live destination diamond'srelayMessageWithHook, asserts the beneficiary is credited exactly 1 USDC, and asserts a second relay reverts on the consumed nonce. The receive path is proven against real attested bytes, reproducible by anyone with a Base RPC.Broadcast evidence committed (ENS-M1 precedent)
