What

Moves the one upstream pin raindex cannot satisfy alongside rainlang 0.2.x: rain-math-float 0.1.1 -> 0.2.1, re-spelled at the two Float import sites (IRaindexV6.sol, deprecated IOrderBookV5.sol). Lockfile and remappings regenerated by forge soldeer update; the superseded line and dir pruned. No alias remapping.

Why

rainlang 0.2.4 spells rain-math-float-0.2.1/ at 46 import sites. Soldeer installs one version per package name, so raindex holding raindex-interface 0.1.5 (spells 0.1.1) and rainlang 0.2.4 (spells 0.2.1) has no expressible pin set: two copies would be two distinct Float types. The ruling on raindex is that mapping one version prefix onto another is not acceptable, so the fix is here, upstream, then a release.

LibDecimalFloat.sol 0.1.1 -> 0.2.1 is signature-identical (diffed every function line); the 0.2.x split only moved the concrete DecimalFloat and LibDecimalFloatDeploy out to rain-math-float-deploy, which this repo never reaches.

forge-std 1.16.1 and rain-sol-codegen 0.1.0 are left alone: nothing under src/ spells either prefix, so no consumer compile reaches them.

QA

  • Discriminating tests: n/a - pin bump and import re-spelling; this repo has no tests (forge test reports no tests found) and the change authors no behaviour.
  • Mutations applied: n/a - no logic line in the diff.
  • Oracle: forge build exit 0 through the repo flake; forge fmt --check clean; the installed 0.2.1 LibDecimalFloat.sol exports the same Float type and function set as 0.1.1.
  • Category check: pin bump only; the consumer-side change (raindex #2863) pins the release this produces.

Downstream: raindex #2863 needs the raindex-interface release cut from this.

Summary by CodeRabbit

  • Chores
    • Updated the rain-math-float dependency from version 0.1.1 to 0.2.1.
    • Updated related integrations to use the newer dependency version.

`IRaindexV6.sol` and the deprecated `IOrderBookV5.sol` import `Float` from
`rain-math-float-0.1.1/`. `rainlang` 0.2.x spells `rain-math-float-0.2.1/`
and Soldeer installs one version per package name, so a consumer holding
both cannot resolve one `Float` type. `LibDecimalFloat.sol` is API-identical
between 0.1.1 and 0.2.1; the concrete `DecimalFloat` and its deploy lib moved
to `rain-math-float-deploy`, neither of which this repo reaches.

`forge soldeer update` regenerated `soldeer.lock` and `remappings.txt`; the
superseded `rain-math-float-0.1.1/` line and dir are pruned.

The dependency update is consistent and builds successfully, but the remapping file still needs its required SPDX header before merge.

@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
