The current example manually builds the crank schedule. Uses the SDK instead (legacy cranks, not Hydra)

Summary by CodeRabbit

  • New Features

    • Updated the crank counter to use the latest scheduling workflow for recurring increments.
    • Added support for preloading an account fixture during local development.
  • Bug Fixes

    • Improved scheduled increment reliability by waiting for on-chain updates instead of relying on a fixed delay.
  • Tests

    • Enhanced integration checks to verify initialization, delegation, scheduled increments, and undelegation results.

Review Change Stack

Warning

Review limit reached

@dhruvja, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 52 minutes

Limit details: You’ve used all 1 included review currently available under your plan.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Walkthrough

Changes

Crank-counter SDK migration

Layer / File(s) Summary
Program identity and SDK CPI integration
crank-counter/anchor/Anchor.toml, crank-counter/anchor/programs/crank-counter/Cargo.toml, crank-counter/anchor/programs/crank-counter/src/lib.rs
Updates the program IDs, pins the SDK to a git revision, and replaces manual task scheduling with ScheduleCrankCpi.
Anchor integration test flow
crank-counter/anchor/tests/crank-counter.ts
Uses typed Anchor RPC calls, asserts initialization, polls for scheduled increments, and uses RPC for delegation and undelegation.
Local account preload configuration
scripts/mAGicPQYBMvcYveUZA5F5UNNwyHvfYh5xkLS2Fr1mev.json, scripts/test-locally.sh
Adds account metadata and preloads the account when starting the local stack.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 2e98d

The legacy SDK migration currently passes the payer account twice when scheduling a crank, which can cause scheduling to fail or use an invalid account layout. Merge should wait until the duplicate account is removed.

55-69: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Remove payer from instruction_accounts.

ScheduleCrankCpi prepends payer, so the call passes [payer, payer, counter] to the scheduling CPI. Pass only ctx.accounts.counter.to_account_info().
