Published deploy scripts execute inside the consumer's Hardhat runtime. Ethers v6 consumers currently fail on v5-only APIs, and replaying copied deployments can repeat approvals, ownership transfers, or proxy deployment.

This change keeps both producers on ethers v5 while making their exports work on either runtime. It uses deployment records for addresses, hardhat-deploy confirmation waits and ABI reads, preserves existing deployments/governance, and skips completed state changes. Reused RandomBeacon and WalletRegistryGovernance deployments still reach verification, so failed Etherscan or Tenderly requests can be retried without new transactions. Matching governance deployment records retain their original constructor arguments and metadata. It also covers the Allowlist/V2 scripts, packages their weights data, and moves verification utilities outside the directory Hardhat treats as executable deploy scripts.

The new consumer CI matrix installs both npm tarballs into independent v5 and v6 projects. It exercises verification-tagged waits, Chaosnet, the V2 upgrade and Allowlist initialization, then clears the migration journal and replays against the same chain. It checks unchanged account nonces and addresses, governance recovery, injected verification failures and retries before and after governance transfer, and approval ABI/read variants including JSON and human-readable fragments. Approval transaction errors remain visible; an unreadable status alone cannot establish that approval succeeded.

Validation: both packages build, prepack and pass their full lint commands; both consumer lanes pass; the six existing verification-helper tests pass. Explorer services are stubbed, while deployment transactions and confirmation waits run on a real local Hardhat network.

Addresses #4319. Package publication, downstream pin bumps and removal of tbtc-v2 overrides remain release follow-ups. The sibling Threshold package fix is threshold-network/solidity-contracts#186.

📝 Walkthrough

Walkthrough

The PR adds an isolated consumer deployment fixture for ethers 5 and 6. It updates Random Beacon and ECDSA deployment scripts to check deployment state, handle proxy and approval variants, and support repeated runs. Package exports and a GitHub Actions workflow support the consumer validation.

Changes

Deployment replay compatibility

Layer / File(s) Summary
Consumer deployment harness
.github/workflows/deploy-consumers.yml, solidity/deploy-consumer/*
Adds an ethers 5 and 6 workflow matrix and an isolated Hardhat fixture. The fixture packs producer packages and checks deployment state, replay behavior, verification paths, and edge cases.
Random Beacon deployment replay
solidity/random-beacon/deploy/*, solidity/ecdsa/external/random-beacon-export/deploy/*
Configures network-specific confirmation counts and checks saved deployment arguments, ownership, authorization, and approval status. The exported JavaScript scripts receive corresponding deployment updates.
ECDSA governance and authorization
solidity/ecdsa/deploy/04_*, 05_*, 08_*, 09_*, 10_*, 13_*, 16_*
Adds checks for existing beacon assignments and authorizations, validates governance links and ownership, reuses compatible governance deployments, and handles allowlist weight-file selection and pending ownership.
ECDSA proxy and approval compatibility
solidity/ecdsa/deploy/03_*, 07_*, 11_*, 12_*, 15_*, 17_*, solidity/ecdsa/deploy-utils/*, solidity/ecdsa/package.json, solidity/ecdsa/test/*, solidity/ecdsa/external/random-beacon-export/README.md, solidity/ecdsa/hardhat.config.ts
Resolves proxy administration through the WalletRegistry proxy, updates approval checks for ABI and status variants, and uses deployment records and upgrades helpers for allowlist and V2 upgrade paths. Package export and verification documentation are also updated.

76-79: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Tolerate missing library records in the reuse branch.

deployments.get throws when a record is absent. The reuse branch at line 10 does not deploy the libraries, so it does not guarantee that the BLS, BeaconAuthorization, BeaconDkg, and BeaconInactivity records exist. A consumer that copies only the RandomBeacon and BeaconSortitionPool records then fails the whole run on an etherscan-tagged network, which is the copied-record scenario this PR targets. Use getOrNull and skip absent records so verification stays best-effort.

♻️ Proposed change
   if (hre.network.tags.etherscan) {
     // Deployment records survive verification failures. Verify them on every
     // run, including when the beacon already owns its sortition pool.
-    await helpers.etherscan.verify(await deployments.get("BLS"))
-    await helpers.etherscan.verify(await deployments.get("BeaconAuthorization"))
-    await helpers.etherscan.verify(await deployments.get("BeaconDkg"))
-    await helpers.etherscan.verify(await deployments.get("BeaconInactivity"))
+    for (const library of [
+      "BLS",
+      "BeaconAuthorization",
+      "BeaconDkg",
+      "BeaconInactivity",
+    ]) {
+      const record = await deployments.getOrNull(library)
+      if (record) {

🌐 Web query:

actions/checkout v4 persist-credentials default official README

💡 Result:

In the official actions/checkout v4 documentation, the default value for the persist-credentials input is true [1][2][3]. When persist-credentials is set to its default (true), the action configures the Git authentication token or SSH key into the local Git configuration [1][2][3]. This allows subsequent Git commands executed within your workflow steps to run in an authenticated context [1][4]. The token is automatically removed during the post-job cleanup phase of the action [1][4]. If you wish to prevent this behavior—for example, to restrict the persistence of credentials—you must explicitly set persist-credentials to false in your workflow configuration [1].

…innet paths

Deploy scripts:
- Reuse a saved governance or sortition pool record only when its constructor
  args match the current registry, beacon or token. A stale record could
  otherwise receive governance of a live contract.
- Governance transfer (ecdsa 10, beacon 08) refuses a foreign governance holder,
  a governance contract linked to another registry or beacon, and a foreign owner.
- ecdsa 13 fails when the beacon is governed by another contract instead of
  logging and succeeding.
- ecdsa 09 gives a clear error when governance is not a WalletRegistryGovernance.
- ecdsa 16 refuses ALLOWLIST_WEIGHTS_FILE on mainnet and logs the weights path.
- ecdsa 17 treats only a reverting allowlist() as V1 and writes the mainnet
  proposal into the project root, not into node_modules.
- Approval scripts skip any application that is not NOT_APPROVED.
- Beacon 04 tolerates missing library records when verifying.
- prepack cleans stale export output; the vendored beacon scripts under
  ecdsa/external are regenerated and their README corrected.

Consumer fixture:
- New edge.js covers mainnet skip flags, the V2 upgrade (mainnet proposal,
  non-owner refusal, V1 detection, repeat and mismatch), and every guard clause.
- smoke.js now asserts final ownership, confirmation depth, the Tenderly proxy
  address, packaged weights and the approval scripts' read targets.
- Shared helpers move to lib.js; transaction checks cover every local account.
- prepare.js refuses a non-empty directory and drops secrets from the environment.
- The workflow is path-filtered, runs weekly, cancels superseded runs and caches
  compilers.
A hung command made the CI job hit its timeout, and a cancelled job loses its
log. Give every external command a time limit and print the duration of each
step, so a hang fails the job with output.
A second run resolved git to the wrapper from the first run, so the new wrapper
executed itself and every later git call hung. The deploy consumer job runs the
action twice and was cancelled at its timeout on every run. Resolve git with the
wrapper directory removed from PATH.
