In `@src/interface/IRaindexV6.sol`:
- Line 17: Update the NatSpec comment in IRaindexV6.sol that still reads “order
book interface” to use the new Raindex branding (e.g., “Raindex interface” or
“Raindex order book interface”) so public docs are consistent with the V6
rename; edit the top-level NatSpec/comment string in the IRaindexV6 interface
declaration to replace the old phrase with the chosen Raindex terminology.
- Around line 433-436: The NatSpec comment in IRaindexV6 refers to an
unversioned event name "AddOrder" but the interface defines the versioned event
as AddOrderV3; update the comment to reference AddOrderV3 so generated docs
point to the correct symbol. Locate the comment block near the
AddOrder/AddOrderV3 usage in IRaindexV6 and replace the unversioned event name
with the exact event identifier AddOrderV3 (keeping the rest of the wording
intact) so it matches the declared event and follows the project's
versioned-naming convention.
- Around line 64-66: Add a compatibility shim so consumers using the old
exported name IOrderBookV6 keep compiling: create a minimal interface file that
imports IRaindexV6 and declares interface IOrderBookV6 is IRaindexV6 {} (or add
an identical deprecated alias in the same module), and include
SPDX/pragma/header consistent with the project; ensure the shim references the
IRaindexV6 symbol and is exported under the original IOrderBookV6 name so
existing imports/inheritance continue to work.

- Line 10: Update the heading "Raindex vs. traditional order books" (and the
other subsection at the same level referenced) to use one-level higher markdown
headers so they increment correctly from the top-level `#` title: change
occurrences of `### Raindex vs. traditional order books` (and the analogous
`###` at the other location) to `##` to restore proper heading hierarchy and
accessibility in the README.

@coderabbitai assess this PR size classification for the totality of the PR with the following criterias and report it in your comment:

S/M/L PR Classification Guidelines:

This guide helps classify merged pull requests by effort and complexity rather than just line count. The goal is to assess the difficulty and scope of changes after they have been completed.

Small (S)

Characteristics:

  • Simple bug fixes, typos, or minor refactoring
  • Single-purpose changes affecting 1-2 files
  • Documentation updates
  • Configuration tweaks
  • Changes that require minimal context to review

Review Effort: Would have taken 5-10 minutes

Examples:

  • Fix typo in variable name
  • Update README with new instructions
  • Adjust configuration values
  • Simple one-line bug fixes
  • Import statement cleanup

Medium (M)

Characteristics:

  • Feature additions or enhancements
  • Refactoring that touches multiple files but maintains existing behavior
  • Breaking changes with backward compatibility
  • Changes requiring some domain knowledge to review

Review Effort: Would have taken 15-30 minutes

Examples:

  • Add new feature or component
  • Refactor common utility functions
  • Update dependencies with minor breaking changes
  • Add new component with tests
  • Performance optimizations
  • More complex bug fixes

Large (L)

Characteristics:

  • Major feature implementations
  • Breaking changes or API redesigns
  • Complex refactoring across multiple modules
  • New architectural patterns or significant design changes
  • Changes requiring deep context and multiple review rounds

Review Effort: Would have taken 45+ minutes

Examples:

  • Complete new feature with frontend/backend changes
  • Protocol upgrades or breaking changes
  • Major architectural refactoring
  • Framework or technology upgrades

Additional Factors to Consider

When deciding between sizes, also consider:

  • Test coverage impact: More comprehensive test changes lean toward larger classification
  • Risk level: Changes to critical systems bump up a size category
  • Team familiarity: Novel patterns or technologies increase complexity

Notes:

  • the assessment must be for the totality of the PR, that means comparing the base branch to the last commit of the PR
  • the assessment output must be exactly one of: S, M or L (single-line comment) in format of: SIZE={S/M/L}
  • do not include any additional text, only the size classification
  • your assessment comment must not include tips or additional sections
  • do NOT tag me or anyone else on your comment
