feat(committor): add v2 delegation reads and settlement builders - #1860
Adds legacy/v2 delegation reads and selects commit and undelegation builders per account. V2 buffers support ordered uploads, partial-upload recovery, and cleanup through DLP. Instruction encoding errors propagate through transaction preparation.
Account discovery, cluster authority tracking, v2 intent limits and settlement recovery, and end-to-end qualification remain unfinished.
CI now runs the RedSuite v2 test stack against the matching pinned DLP program. V2 activation is expected to fail while account discovery remains legacy-only.
Metadata reads fetch both PDA layouts and the referenced v2 clusters. V2 uploads read the existing buffer and confirm each chunk before the next write. RPC overhead and the 200k CU write budget still need measurement.
Read legacy record/metadata PDAs and v2 DelegationState in matching RPC
batches. Validate account ownership, discriminators, delegation sessions,
and Direct cluster identities, and reject ambiguous protocol layouts.
Expose the resulting commit IDs through the existing provider.
Carry the delegation protocol into commit and undelegation tasks so each
account uses the matching DLP builder. Preserve the ScheduleCommit APIs
and propagate instruction encoding failures through transaction planning
and preparation instead of panicking.
Keep v2 payloads inline while DLP has no StateBuffer close instruction.
Reject v2 buffer preparation and mark the enablement and cleanup sites
with CHECKPOINT links to delegation-program#270.
This is the initial committor portion of #1858. Account discovery and
cluster authority handling, protocol-aware intent limits and recovery,
buffer preparation and cleanup, and v2 qualification remain unfinished.
Committor now reads legacy and V2 delegation information and selects protocol-specific task instructions. The change adds fallible instruction construction and error propagation, V2 StateBuffer upload, resume, validation, and cleanup behavior. RedSuite actions now build and use a revision-matched delegation-program fixture.
Changes: V2 delegation execution
Layer / File(s)
Summary
Delegation info and task construction Cargo.toml, committor/src/shared/account_state.rs, committor/src/execution/task_builder.rs, committor/src/execution/intent.rs, committor/src/test_utils.rs
Delegation reads support legacy and V2 layouts and validate V2 cluster accounts. Task construction uses delegation info to set task versions, rent payers, and undelegation request behavior.
Task instructions select legacy or V2 builders. Buffer writes and cleanup carry the delegation version, and instruction methods return encoding errors where applicable.
Instruction errors and transaction planning committor/src/shared/tasks/{task_strategist.rs,utils.rs}, committor/src/intake/intent_limits.rs, committor/src/execution/{error.rs,preparation/error.rs,test_utils.rs}, committor/src/execution/transaction/...
Instruction and account collection failures propagate through strategy and transaction preparation. Fit checks reject failed estimates, and lookup-table key fallbacks retain prior or original keys.
V2 StateBuffer upload and cleanup committor/src/execution/cleanup.rs, committor/src/execution/preparation/delivery_preparator.rs
V2 uploads validate existing buffers and resume matching partial uploads. Cleanup builds close instructions in batches and deduplicates buffer-close tasks by buffer PDA.
RedSuite DLP fixtures
Layer / File(s)
Summary
Build and run DLP fixtures .github/actions/build-redsuite/action.yml, .github/actions/run-redsuite/action.yml
The build action validates and caches fixtures using the DLP revision, then builds the program on a cache miss. The run action sets the DLP artifact path and uses a pinned RedSuite commit.
magicblock-labs/magicblock-validator#1859: This PR migrated the validator to a prior delegation interface revision; this change updates that dependency and uses V2 builders.
This change enables v2 settlement test scenarios before the validator can discover v2 delegations, so the correctness CI job can fail. Owner-requested v2 undelegations cannot complete, and a retried v2 upload against a mismatched buffer fails permanently. Resolve these before merging.

Explanation
The title "feat(committor): add v2 delegation reads and settlement builders" matches the main changeset. The changes add legacy and V2 delegation reads (account_state.rs, DelegationInfo, DelegationVersion), version-based selection of commit and undelegation builders (commit_finalize_task.rs, mod.rs, buffer_task.rs), and V2 buffer upload and cleanup logic (delivery_preparator.rs). The title is concise and follows conventional commit style. It does not mention the error propagation changes or the CI/RedSuite changes, but those are secondary.
Full details: Description check
Explanation
The description is related to the changeset. It states that the PR adds legacy and V2 delegation reads, selects commit and undelegation builders per account, adds V2 buffer uploads and cleanup through DLP, and propagates instruction encoding errors. It also covers the reviewer notes on unfinished work, the RedSuite CI changes (.github/actions), the metadata reads, and the dependency blocker on delegation-program PR #271. The description matches the summarized file changes.

Update the DLP interface to 3fb00596169d5963fbada0bf90e099e731fbacb4
from delegation-program#271, which adds CloseStateBuffer and records the
buffer rent payer. Preserve unrelated dependency selections in Cargo.lock.
Enable v2 buffered delivery and use WriteStateBuffer for full account data
and encoded diffs. Validate existing buffer identity, payer, length, and
payload before resuming an upload. Reuse finalized buffers and confirm
each chunk before sending the next, while retaining parallel legacy
writes. Reject payloads beyond DLP's buffer limit before uploading.
Close v2 buffers through DLP and refund the committor that funded them.
Deduplicate cleanup by buffer PDA so legacy and v2 buffers with the same
account and commit ID remain distinct. Preserve buffers while settlement
is uncertain, and propagate close-instruction encoding errors.
Remove the StateBuffer CHECKPOINT blockers. Extend the existing wire-size
tests for both protocols and mixed cleanup batches, and add coverage for
ordered uploads, partial-upload recovery, completed-buffer reuse, payload
mismatches, and cleanup retries.
V2 writes use a 200,000 CU budget pending on-chain measurement. Matching
DLP deployment and RedSuite qualification are still required; the other
account-discovery and settlement integration work in #1858 remains open.

# Delegation program
Delegation module for https://arxiv.org/pdf/2311.02650.pdf
## Public Api
* `Instruction Builders` – utilities to generate Instructions.
* `Args` – Instructions arguments structures.
* `Consts` – Program constants.
* `Errors` – Custom program errors.
## Program
* `Entrypoint` – The program entrypoint.
* `Processors` – Instruction implementations.
## Important Instructions
* `Delegate` - Delegate an account
* `CommitState` – Commit a new state
* `Finalize` – Finalize a new state
* `Undelegate` – Undelegate an account
## Tests
To run the test suite, use the Solana toolchain:
cargo test-sbf --features unit_test_config
For line coverage, use llvm-cov:
cargo llvm-cov --test test_commit_state
(llvm-cov currently does not work with instructions with CPIs e.g.: delegate, undelegate)
## Integration Tests
The integration tests are located in the `tests/integration` directory. The tests consist of a Bolt/Anchor program that uses the delegation program to delegate, commit, and undelegate accounts. This can be also used a reference for how to interact with the program.
To run the integration test, use Bolt or Anchor:
cd tests/integration && bolt test
or:
cd tests/integration && anchor test
## Upgrading the Program
Upgrades go through a Squads multisig whose vault holds the upgrade authority. CI only proposes them.
1. Run Actions → Propose Program Upgrade with the target `cluster` (start with `dry_run`). It builds `dlp` verifiably, uploads a buffer and opens a Squads proposal that upgrades the program and records its verified build. The job summary shows the proposal number and the executable hash.
2. Members review and approve:
* mainnet: in the Squads app;
* devnet: with the shared command-line tools, run locally with your own keypair:
node approve.mjs --multisig <MULTISIG> --keypair <your keypair> <proposal #> --hash <executable hash>
3. Once approved, any member with Execute executes it.

Recover a mismatched V2 buffer before ending the intent.
A failed base-account fetch can rebuild a retried DiffInBuffer task as full-state data. The V2 prefix check then returns InvalidStateBuffer. This error is non-transient, so the executor ends the current intent instead of retrying it.
The pinned V2 CloseStateBuffer instruction supports idempotent cleanup of abandoned partial uploads. Enter the existing cleanup-and-retry path for InvalidStateBuffer.

`InternalError::InvalidStateBuffer` through the existing cleanup-and-retry path,
preserving the current behavior for other errors.

Use DelegationInfo for the committor view of legacy and v2 delegation data, avoiding a name collision with the on-chain DLP DelegationMetadata type.
Rename DelegationProtocol to DelegationVersion and its protocol fields to version. Update provider methods, task builders, error names, local variables, and existing test fixtures to use the same terminology.
Preserve the DLP DelegationMetadata type and metadata PDA helpers. Settlement behavior and instruction encoding are unchanged.

Do not send owner-requested V2 undelegations through this instruction.
When DelegationInfo.undelegation_requester is OwnerProgram, TaskBuilder::follow_up_tasks sets include_undelegation_request. This V2 branch ignores that flag. The pinned DLP commit processor preserves the OwnerProgram requester, and its V2 undelegation processor rejects that requester. Consequently, an owner-requested V2 commit-and-undelegate intent cannot complete. Add a supported V2 owner-request path, or reject this intent before settlement until DLP supports it. (raw.githubusercontent.com)
As per path instructions, prioritize “API contract correctness” in Rust workspace code.

Pin RedSuite to the top of its three-PR v2 coverage stack: lifecycle,
buffered settlement and cleanup, and mixed legacy/v2 intents.
Read the DLP revision from the validator dependency and require RedSuite
to use the same interface revision. Build that program with the SBF
fixtures, include its revision in the artifact cache key, and load the
result through REDSUITE_DLP_SO instead of the cloned mainnet program.
This enables real v2 qualification on Linux CI. The scenarios deliberately
require normal v2 discovery and activation; they do not seed legacy PDAs
to bypass the remaining Chainlink integration gap.

Do not enable the v2 RedSuite scenarios before Chainlink resolves v2 delegations.
The pin at .github/actions/run-redsuite/action.yml:37 selects a RedSuite revision whose default redshift run includes three v2 scenarios. The PR states that these scenarios use normal v2 discovery and activation. Chainlink resolves delegated accounts only through the legacy delegation-record PDA, so those scenarios can fail to activate their accounts. The correctness job runs for this PR because the change touches .github/actions/run-redsuite/**, and it can fail on these scenarios.
Keep the v2 scenarios out of the correctness job until Chainlink implements v2 discovery and activation. Alternatively, land that Chainlink work before this pin merges.

What changed
Adds legacy/v2 delegation reads and selects commit and undelegation builders per account. V2 buffers support ordered uploads, partial-upload recovery, and cleanup through DLP. Instruction encoding errors propagate through transaction preparation.
Related to #1858.
Reviewer notes
Account discovery, cluster authority tracking, v2 intent limits and settlement recovery, and end-to-end qualification remain unfinished.
CI now runs the RedSuite v2 test stack against the matching pinned DLP program. V2 activation is expected to fail while account discovery remains legacy-only.
Metadata reads fetch both PDA layouts and the referenced v2 clusters. V2 uploads read the existing buffer and confirm each chunk before the next write. RPC overhead and the 200k CU write budget still need measurement.
Blocker
Depends on magicblock-labs/delegation-program#271 being merged and deployed before these validator changes are merged and released.
