Monitoring

[vzotova]

• manage.py monitor — nightly probe of every chain that keeps one GitHub issue in sync: opens on a prod deviation, comments when it changes, closes when clean. No secrets; it uses the public_rpc_url each deployment file already records.
• Nightly --bytecode --from-commit — recompiles each contract from the commit it was deployed at, matching ~264 contracts byte-for-byte (without --from-commit, 12 chains report every row uncomparable).
• manage.py verify — submits sources to Etherscan v2 (vyper-json), falling back to Blockscout for chains it doesn't list; 397 of 502 verifiable contracts are now verified, up from 155.
• manage.py site — renders the registry as one searchable page and publishes it to Pages on each deploy (needs Pages enabled, source = GitHub Actions).
• PR-scoped on-chain probe — a PR touching a deployment file gets that chain probed and commented on, catching a hand-edited address that offline checks can't see.
• pre-commit/action in CI — replaces hand-pinned black/isort so CI and the local hook can't drift; contracts/ is excluded from end-of-file-fixer because vyper hashes the source into the deploy bytecode.

Findings

• devnet/monad and devnet/etherlink record 42 addresses that hold no code, confirmed four ways.
• devnet/etherlink and devnet/plume publish public_rpc_url values that don't work.
• Prod is clean on every check.
