An official provider source changes
Delta Code captures and fingerprints the artifact, then normalizes it into a provider-independent change.
source.capturedA provider change enters. A verified draft PR comes out.
Delta Code turns external change management into a durable review workflow, with GPT-4o handling repository-specific judgment and deterministic systems preserving proof.
Connected repositories are assessed
Dependency inventory and language analyzers locate supported call sites and expose coverage limits.
impact.assessedGPT-4o proposes the migration
Bounded provider, repository, and call-site context produces a schema-validated plan, patch, tests, and commands.
ai.proposalPatch policy constrains the output
Only supplied files, expected hashes, known call sites, and approved command arrays can advance.
patch.validatedThe exact patch runs in a sandbox
Build, lint, type-check, test, and behavioral checks produce deterministic evidence.
sandbox.verifiedGPT-4o reviews against the evidence
The model identifies grounded findings and recommends approve, revise, snooze, or decline.
ai.reviewA draft pull request reaches the developer
Delta Code publishes the verified patch, source links, checks, uncertainty, and immutable attempt history.
pull_request.draft“AI proposes. Evidence proves. You decide.”
GPT-4o supplies the judgment required to migrate unfamiliar repository code. Deterministic systems establish what source was captured, what code was affected, what patch ran, and which checks passed.
