No review-workflow replacement required
ShipCheck can sit on top of the GitHub workflow your team already uses instead of making a new PR interface, stack model, or merge queue the center of adoption.
Move pull requests faster.Know which ones deserve to move.
Graphite is an end-to-end code-review workflow built around AI review, stacked pull requests, its PR interface, merge queues, inboxes, chat, CLI tooling, and developer velocity. ShipCheck does not try to replace that workflow. It adds a persistent behavioral verification layer to the repository you already use.

Context for review. Memory for the system.
Graphite optimizes how changes move through review. ShipCheck focuses on what those changes must preserve and what proof is required before they move. Behavior Contracts, evidence policy, risk-aware verdicts, Behavioral Diff, and Behavior History make ShipCheck a behavioral-governance layer rather than another PR interface or merge workflow.
ShipCheck
Behavior survives individual PRs
Important expectations become durable repository memory rather than existing only inside the review of one change.
Regression history is first-class
Behavior History records how an expectation changes across many pull requests rather than optimizing only the flow of those pull requests.
Historical origin explains old safeguards
ShipCheck can recover where a behavior came from so a later cleanup can distinguish dead code from a safeguard introduced for a real reason.
Graphite
Stacked pull requests
Graphite lets teams build and review chains of dependent, smaller PRs.
Integrated merge workflow
Its stack-aware merge queue, PR interface, inbox, CLI, and notifications optimize review throughput.
AI review and chat
Graphite automatically reviews PRs and provides suggested fixes and conversational assistance inside its review experience.
What changes in practice.
These differences determine whether context disappears after review or becomes durable protection for the next change.
ShipCheck does not need to own the workflow to protect the code.
It is designed as a focused verification layer: connect the repository, retain important behavioral expectations, and evaluate future changes without replacing your PR UI or merge mechanics.
ShipCheck optimizes for behavioral continuity, not PR throughput.
The central question is not how quickly a PR moved through review. It is whether a safeguard, contract, authorization rule, validation behavior, or other invariant silently changed.
Repository memory remains useful through workflow changes.
Behavior Contracts and their immutable history stay attached to the software even if the team later changes editors, coding agents, reviewers, branching conventions, or review tooling.

| Capability | ShipCheck | Graphite | Context |
|---|---|---|---|
| AI pull-request review | Yes | Yes | |
| Dedicated PR interface | No: GitHub-native workflow | Yes | |
| Stacked pull requests | Not required | Core capability | |
| Stack-aware merge queue | Not the product focus | Yes | |
| Persistent software behavior object | Yes: Behavior Contracts V2 | Not the primary abstraction | |
| Explicit behavior lifecycle | Yes | Not assessed here; consult current vendor documentation | |
| Historical behavior origin | Yes | Not assessed here; consult current vendor documentation | |
| Works without replacing PR workflow | Core design | Best value comes from broader Graphite workflow adoption |
Your PR workflow moves changes. ShipCheck remembers what those changes must preserve.
Add behavioral verification without turning repository memory into another workflow migration.
