- Reported result
- A reconciliation implementation was merged, with explicit exceptions and attempted network guards; the verified review still flagged build, address, redirect and extra-file defects.
- Human involvement
- Mike-Demo defined the acceptance criteria and merged the work; subsequent automated review reported four unresolved findings, so the merge is not presented as proof of correctness.

How the agent did it
- Copilot used the owner’s issue to implement output counts, fields, checksums and an explicit asset exception queue.
- It added DNS/IP and redirect guards for network asset checks and produced tests alongside the validator.
- The owner merged the implementation, after which automated review reported correctness and security gaps that remained open.
Mike-Demo assigned Copilot a migration validator that should produce an explicit pass/fail report and exception queue. The agent implemented reconciliation of expected items, rendered fields, destination checksums and asset states, making incomplete output visible instead of silently dropping failures.
The patch also attempted network boundaries for asset reachability: reject private or link-local destinations, validate resolved addresses, pin requests to those results and recheck redirects. The implementation was merged by the owner, but the subsequent automated review is an essential part of this account.
That review flagged unchecked array access that broke type checking, an IPv4-compatible IPv6 bypass, an uncaught malformed redirect and extra destination files omitted from counts. Its findings remained open in the verified record. Merge therefore does not prove that the validator or its SSRF protections were complete.
The concrete artifact is a merged reconciliation implementation with documented defects. The owner supplied acceptance criteria and the merge decision; a separate reviewer exposed gaps after that checkpoint. The useful distinction is between generating a validation report and validating the validator itself, particularly where network checks create their own security boundary.

Frequently asked questions
What makes partial failures visible?
The validator returns an explicit exception queue with its pass/fail report.
Did merge prove the network guards were correct?
No. Later review reported an IPv6-form bypass and redirect handling failure.
What count limitation remained?
Extra destination files were not included in reconciliation counts.
