PR Review — docs: update create-api-key usage + CI secrets

Overall this is a clean, well-scoped PR with good documentation improvements. The commit messages are clear and explain the why for each change. A few items worth discussing before merging:

Bug / Usability Issue

package.json — hardcoded address in apikey-gen script

-"apikey-gen": "... --subject=apikey ..."
+"apikey-gen": "... --subject=0x804e49e8C4eDb560AE7c48B554f6d2e27Bb81557 ..."

The old --subject=apikey was broken (not a valid EOA), but the fix introduces a different problem: 0x804e49e8C4eDb560AE7c48B554f6d2e27Bb81557 is hardcoded — presumably the address derived from the CI's TEST_PRIVATE_KEY. Local developers with a different TEST_PRIVATE_KEY will silently generate an API key bound to someone else's address. Requests authenticated with that key will either fail or return data for the wrong owner.

Suggestion — derive the address from TEST_PRIVATE_KEY dynamically in the script, or replace the address with a placeholder and print a hint:

# Option A: use a placeholder and fail loudly
"apikey-gen": "sh -c '[ -n \"$SUBJECT_ADDRESS\" ] || (echo \"ERROR: set SUBJECT_ADDRESS to your wallet address\" && exit 1); API_KEY=$(docker compose exec aggregator /ava create-api-key --role=admin --subject=$SUBJECT_ADDRESS) && ...'",

# Option B: derive from TEST_PRIVATE_KEY via cast/ethers if available

The CI use (dev-test-on-pr.yml) is fine as long as the hardcoded address matches what the CI's TEST_PRIVATE_KEY yields — but there's no assertion of that in the workflow, so a future key rotation could silently break tests.

Minor Issues

CHAIN_ENDPOINT secrets migration — silent failure risk

Moving from vars to secrets is correct (per commit message, endpoints embed API keys). One thing to verify: each of the four matrix environments (sepolia, ethereum, base, base-sepolia) must now have CHAIN_ENDPOINT configured as a GitHub environment secret, not a variable. If any environment is missing it, the workflow will receive an empty string and likely fail with a confusing error rather than a missing-secret message. GitHub doesn't warn on missing secrets the way it does for missing required inputs.

.env.dev loading fix — dotenv precedence

-if (currentEnv && currentEnv !== "dev") {
+if (currentEnv) {

This is the right fix (.env.dev was being silently skipped for the default dev environment). One edge case: dotenv loads the first occurrence of a key and ignores subsequent ones by default. Since .env is loaded before .env.dev, any key set in both files will use the .env value — .env.dev overrides won't work. This is probably fine for now but worth documenting in the comment block above if users are expected to put AVS_API_KEY in .env.dev.

What's Good

• The README.md change correctly documents that --subject must be a 0x-prefixed EOA address — this was a real footgun with the old --subject=apikey placeholder.
• The examples/example.ts header additions for getExecutions/getExecution CLI commands are clear and follow the existing pattern.
• The AVS_API_KEY setup documentation in the example file is thorough and should unblock new contributors who were confused about how to mint the JWT.
• Moving BUNDLER_URL to secrets is correct — the commit message confirms it embeds an API key query parameter.

---

Verdict: The documentation improvements are solid. The main concern is the hardcoded address in apikey-gen — it will silently break local dev for anyone whose wallet differs from that address. Recommend addressing that before merge (or at minimum adding a comment warning users to replace it).
