Adds a direct-mode DLP v2 lifecycle scenario: delegate, write and commit, then write and undelegate. It checks exact base-chain data, ownership, commit ID, and delegation-state cleanup.
The fixture uses the validator's pinned DLP interface. REDSUITE_DLP_SO loads the matching local program; the existing scheduling API stays unchanged.
Requires the v2 validator integration in validator #1860. Its account discovery currently reads only legacy delegation records, so v2 activation is expected to fail until that path is updated. Local startup is blocked by the missing macOS Yellowstone plugin.
No actionable comments were generated in the recent review.
Walkthrough
The change adds a local DLP program override, a fixture instruction for v2 delegation, and an explicit committor scenario. The scenario checks base-chain state after a commit and after undelegation.
Changes: DLP v2 lifecycle
Layer / File(s)
Summary
Configure local DLP program Cargo.toml, core/src/topology/*, core/src/frontend.rs, README.md
Adds REDSUITE_DLP_SO to the base-plan configuration. When set, the path must be a file and is loaded as the DLP program. The base plan skips cloning that program, and the README documents setup for the scenario.
Adds the DelegateV2 instruction and its builder and handler. The handler validates the supplied accounts, transfers cell data through a temporary buffer, invokes the delegation instruction, and returns the buffer to the payer.
Implement and register lifecycle scenario redshift/Cargo.toml, redshift/src/scenarios/committor/*, redshift/src/scenarios/mod.rs
Adds v2 fixture helpers and registers the explicit-only dlp_v2_lifecycle scenario. It checks a committed write and a later undelegated write, including base-chain data, ownership, and delegation-state presence.

Full details: Linked Issues check
Explanation
[#281] Requirements are coding requirements. The summary shows implementation for each one:
Small lifecycle scenario with shared direct-mode setup and real v2 delegation: redshift/src/scenarios/committor/v2.rs adds the Fixture that initializes a direct-mode cluster. delegate_v2 in programs/fixture/src/build.rs and the DelegateV2 handler in programs/fixture/src/execute/mod.rs create real v2 delegation. redshift/src/scenarios/committor/dlp_v2_lifecycle.rs adds the scenario. It is registered in redshift/src/scenarios/mod.rs.
Harness can load the matching DLP build: DLP_SO_ENV (REDSUITE_DLP_SO) in core/src/topology/config.rs loads a local DLP program on base. It is exposed in core/src/frontend.rs and re-exported in core/src/topology/mod.rs.
Account is discovered, modified, committed, and undelegated through existing scheduling: the scenario writes value 11, commits it, writes value 22, and undelegates. The PR description states the scheduling API is unchanged.
DelegationState verification: create_cell checks delegation state fields.
Exact base data and ownership: await_base checks data and owner. The scenario checks that the cell reaches the base chain under the delegation program ID after commit and under the REDSHIFT program ID after undelegate.
Commit-ID advancement: the commit_id helper exists. The scenario verifies commit ID 1 after the first commit. The summary does not show an explicit check after the second settlement.
Delegation-state cleanup: the scenario checks that the delegation-state account is absent after undelegate.
Legacy behavior remains covered: the summary lists no changes to existing legacy committor scenarios.
Limits: the PR description states that v2 activation fails until validator #1860 updates legacy-only account discovery. Local startup is also blocked by the missing macOS Yellowstone plugin. The scenario therefore has no recorded passing run in this review. This assessment covers implementation evidence from the summary only. It does not confirm runtime behavior.
Full details: Docstring Coverage
Explanation
Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 12 functions across 10 files. (2 skipped: 2 unsupported.)
Resolution
Write docstrings for the functions missing them to satisfy the coverage threshold.

Explanation
Most changes connect to #281:
Cargo.toml, programs/fixture/Cargo.toml, redshift/Cargo.toml: add magicblock-delegation-program-interface, which the PR description names as the pinned DLP interface.
programs/fixture (lib.rs, build.rs, execute/mod.rs): add the DelegateV2 instruction needed for v2 delegation.
redshift/src/scenarios/committor/*: add the scenario and fixture.
core/src/topology/config.rs, core/src/frontend.rs, core/src/topology/mod.rs: add the REDSUITE_DLP_SO harness override.
README.md, programs/README.md: document the new behavior.
One dependency is not connected. redshift/Cargo.toml and the workspace Cargo.toml add the wheels Git dependency from the snawaz/nested-layout-options branch. The PR description does not mention it. The summaries of the scenario, fixture, and harness files do not show any use of wheels. This is not proof that it is unused, because the summary is not the full diff. The purpose of this dependency is unknown from the available evidence.
Resolution
Confirm which code uses the wheels dependency and why it is needed for #281. If no code in this PR uses it, remove the wheels entry from the workspace Cargo.toml and redshift/Cargo.toml. Explain its purpose in the PR description if it stays.

Give the v2 lifecycle cell a payload so commit and undelegation payload loss is detected.
The cell is created with CellHeader::SIZE, so it has no payload bytes. The base snapshot comparison then covers only the header. A payload lost during commit or undelegation would pass.
The write call after delegation refills the whole payload, so payload lost during delegation is overwritten before the commit. A larger cell detects loss in the commit and undelegation transfer, not loss confined to delegation.
🧪 Suggested fix
- let cell = fixture.create_cell(0, CellHeader::SIZE as u32).await?;+ let cell = fixture.create_cell(0, (CellHeader::SIZE + 64) as u32).await?;

Review comment at @redshift/src/scenarios/committor/dlp_v2_lifecycle.rs at line
21:
Increase the cell size in the v2 lifecycle test’s `fixture.create_cell` call
from header-only to include a payload, preserving the existing delegation and
write flow so the base snapshot comparison detects payload loss during commit or
undelegation.
