…resolution (EXSC-767)
A failed on-chain periphery lookup (RPC error) returned error text that was written as invalid JSON, collapsing the whole jq merge to {} and unconditionally overwriting the recorded Periphery section.
Workers now classify each lookup (failure marker / unregistered / valid address) so an error can no longer poison the merge, and the write keeps the existing Periphery section unchanged when any lookup failed or a clean run resolves no addresses while the log holds some. This also fixes the second write site (saveDiamondFacetsAndPeriphery) via the periphery-only temp output.

ChangesPeriphery lookup preservation
Estimated code review effort: 3 (Moderate) | ~20 minutes Mergeability Score: 🔵 Low · up to The change protects populated periphery data from being cleared after failed lookups, but malformed Tron addresses may still be accepted and persisted in some cases. The PR is mergeable with explicit owner awareness or follow-up to tighten that validation. Possibly related PRs

Which Linear task belongs to this PR?
Fixes EXSC-767
Why did I implement it this way?
The wipe had two layers, so the fix addresses both rather than only the unconditional write the ticket pointed at. First, the parallel worker never checked the lookup's exit code —
universalCallrunscast call … 2>&1, so a transient RPC error returns error text as the "address". That text was written verbatim as invalid JSON ({"ERC20Proxy": "Error: …"}), which then madejq -s 'add'fail across every contract and fall back to{}. Second, that{}was written to.Peripheryunconditionally, so a single RPC blip silently replaced the whole populated section. The worker now classifies each lookup — failure marker (no JSON emitted, so it can't poison the merge), genuinely-unregistered (""), or valid address (validated with the existingisValidEvmAddress/isValidTronAddresshelpers). A single decision point then keeps the existing Periphery section unchanged and warns when any lookup failed, or when a clean run resolves zero addresses while the log already holds some; only a clean, non-empty resolution does the authoritative full replace, so legitimate periphery removals still record correctly. Because that decision also drives theperiphery-onlytemp-file output, the second write site (saveDiamondFacetsAndPeriphery, which had the same unconditional.Periphery = $periphery[0]) is fixed transitively — its merge now receives preserved values instead of{}. Verified withbash -nand a standalone 13-case logic harness covering the reported wipe, clean replace, both empty-result guards, fresh-network bootstrap, and a legitimate single-contract removal; the repo has no bash unit-test framework so no test file is added to the diff.Checklist before requesting a review
