Bumps the Soldeer dependency rain-math-binary from 0.1.1 to 0.1.3.

The repo uses version-suffixed Soldeer remappings, so the version string moves in place on both sides of the = in remappings.txt. That form is deliberate and is preserved — no unversioned alias is introduced.

No first-party source in this repo imports rain-math-binary at all. git grep rain-math-binary -- src test script returns nothing. The dependency exists here purely to satisfy transitive imports from other dependencies.

BLOCKED — this cannot compile until upstream republishes

This PR is correct as a mechanical bump but CI is expected to be red, and the reason is upstream, not in this diff.

foundry.toml sets [soldeer] recursive_deps = false, so the root remappings.txt is the only import resolver for the whole dependency tree. Two compiled dependency sources hard-code the 0.1.1 prefix:

  • dependencies/rain-interpreter-interface-0.1.0/src/lib/parse/LibParseMeta.sol
  • dependencies/rain-interpreter-interface-0.1.0/src/lib/codegen/LibGenParseMeta.sol
  • dependencies/rainlang-0.1.2/src/lib/op/bitwise/LibOpBitwiseCountOnes.sol

each with:

import {LibCtPop} from "rain-math-binary-0.1.1/src/lib/LibCtPop.sol";

(dependencies/rain-extrospection-0.1.0/test/src/lib/EVMOpcodes.t.sol does the same, but in test sources that this repo does not compile.)

Once the root remapping moves to rain-math-binary-0.1.3/, the rain-math-binary-0.1.1/ prefix no longer resolves and those imports dangle.

No currently published version combination fixes this: the latest published rain-interpreter-interface (0.1.2) and rainlang (0.1.8) both still pin rain-math-binary 0.1.1. This repo can only go green after rain-interpreter-interface is republished against rain-math-binary 0.1.3, and then rainlang is republished on top of that.

Constraint for the eventual rainlang bump

foundry.toml carries a deliberate pin comment:

# rainlang 0.1.2: parser emits V3 IntOrAString (see LibParseLiteralDiaKeyTest).
rainlang = "0.1.2"

Whoever lands the follow-up rainlang bump has to reckon with that: the replacement rainlang must still emit V3 IntOrAString, or test/src/lib/parse/LibParseLiteralDiaKey.t.sol and the CLAUDE.md V3 IntOrAString contract have to be revisited alongside it. Do not bump past this pin just to chase a compiling build.

Changes

  • foundry.toml"rain-math-binary" = "0.1.1" -> "0.1.3"
  • remappings.txtrain-math-binary-0.1.1/=dependencies/rain-math-binary-0.1.1/ -> rain-math-binary-0.1.3/=dependencies/rain-math-binary-0.1.3/ (exactly one rain-math-binary line; the stale 0.1.1 line that soldeer update leaves behind was removed by hand)
  • soldeer.lock — regenerated by forge soldeer update; only the rain-math-binary entry moved (version, url, checksum, integrity). No other dependency was touched.

No .gas-snapshot exists in this repo, so there is nothing to regenerate. No foundry.lock exists either; soldeer.lock is the only lockfile.

QA

  • Discriminating tests: n/a - no first-party source or test changed. This diff is three metadata/lockfile lines (foundry.toml, remappings.txt, soldeer.lock); there is no new behavior to discriminate. The existing suite is the discriminator, and its baseline result is recorded below.
  • Mutations applied: n/a - a dependency-version bump has no first-party line to mutate. The bump itself is the perturbation, and the whole 46-test suite is the killing set; it currently fails to even compile, which is reported below rather than hidden.
  • Oracle: the upstream published artifacts, independent of this repo. rain-math-binary 0.1.1 -> 0.1.3 is NatSpec/comment-only in src/lib/LibCtPop.sol, so the expected behavioral delta is exactly zero. Any behavioral change the suite reported would therefore be a defect in this diff, not in the library. The compile failure below is a resolver failure, not a behavioral one.
  • Category check: the task asks for (A) the foundry.toml version, (B) soldeer update lockfile regeneration, (C) remappings.txt on both sides of the = keeping the version suffix, (D) zero remaining rain-math-binary-0.1.1 in tracked files. Covered A, B, C, D. Green CI is NOT covered, and is blocked upstream for the reason stated above.

Verification is delegated to CI, and CI is expected to be RED for the upstream reason stated above. I am not claiming this is green.

What I actually ran:

  1. nix develop -c forge soldeer install && forge build && forge test on unmodified main (baseline, before any edit):
    Ran 14 test suites in 268.29ms (1.09s CPU time): 46 tests passed, 0 failed, 0 skipped (46 total tests)baseline main is GREEN, including the Base fork tests, which resolved against the public https://mainnet.base.org default. So there is no pre-existing red to hide behind.

  2. nix develop -c forge soldeer update — exit 0. Diff of soldeer.lock confirmed to touch only the rain-math-binary entry.

  3. rm -rf dependencies out cache && nix develop -c forge soldeer install && forge build after the bump — FAILED, exit 1, with exactly the dangling-import failure described above:

Error (6275): Source "dependencies/rain-math-binary-0.1.1/src/lib/LibCtPop.sol" not found: File not found.
 --> dependencies/rain-interpreter-interface-0.1.0/src/lib/parse/LibParseMeta.sol:5:1
 --> dependencies/rain-interpreter-interface-0.1.0/src/lib/codegen/LibGenParseMeta.sol:13:1
 --> dependencies/rainlang-0.1.2/src/lib/op/bitwise/LibOpBitwiseCountOnes.sol:9:1

This is not a semantic change in the library — the 0.1.1 -> 0.1.3 delta in rain-math-binary is NatSpec/comment-only in src/lib/LibCtPop.sol. It is purely the versioned-remapping prefix no longer resolving for dependencies that have not been republished.

What I did not run: forge test after the bump, slither ., forge fmt --check, rainix-sol-single-contract, reuse lint, or the copy-artifacts regeneration. forge build is a prerequisite for all of them and it does not pass, and further local verification was descoped in favour of getting this staged. CI will report them.

Sweep check: git grep rain-math-binary-0.1.1 over tracked files returns zero occurrences. Remaining occurrences live only inside the gitignored dependencies/ directory; those are published upstream artifacts and are correctly left alone.

The devshell-generated .pre-commit-config.yaml was deliberately kept untracked and out of this commit; the staged diff is exactly three files.

Summary by CodeRabbit

  • Chores
    • Updated the pinned math dependency to version 0.1.3 for improved compatibility and maintenance.

Version-suffixed soldeer remapping moves in place; no first-party
source imports rain-math-binary directly.

Mergeability Score: 🔴 Critical · up to e6985

This change points dependency resolution at rain-math-binary 0.1.3 while published dependencies still require 0.1.1, so the repository no longer compiles. Merge should remain blocked until compatible upstream releases are available or the version bump is reverted.

Blocked-on: Diagnosed from the CI logs and reproduced locally at e6985e5 in the repo's own CI devshell. All three red checks (rainix-sol test, rainix-sol static, copy-artifacts) fail with the identical resolver error, Source "rain-math-binary-0.1.1/src/lib/LibCtPop.sol" not found, raised from DEPENDENCY sources, not from anything in this diff.

This is not fixable in this repo, and not fixable by any version selection anywhere. rain-math-binary 0.1.3 was published 2026-07-19. The latest published rain-interpreter-interface (0.1.2, 2026-06-15) and the latest published rainlang (0.1.8, 2026-07-03) both PREDATE it, and both still hard-code the rain-math-binary-0.1.1 import prefix. Verified by installing them, not inferred: rain-interpreter-interface-0.1.2/src/lib/parse/LibParseMeta.sol and src/lib/codegen/LibGenParseMeta.sol, and rainlang-0.1.8/src/lib/op/bitwise/LibOpBitwiseCountOnes.sol. With recursive_deps = false, the root remappings.txt is the only resolver for the whole tree, so moving it to 0.1.3 dangles those imports.

The unblock is an ORDERED republish cascade, and its root is rain-interpreter-interface: it imports rain-math-binary-0.1.1 directly and depends on no other rain package that does. rainlang imports both rain-interpreter-interface-0.1.0 and rain-math-binary-0.1.1 directly, so it is second. Leaf repos like this one are third. Nothing here can move until (1) rain-interpreter-interface is republished against rain-math-binary 0.1.3, then (2) rainlang is republished against both.

Constraint for the eventual rainlang bump: foundry.toml pins rainlang = 0.1.2 with the comment that its parser emits V3 IntOrAString (see test/src/lib/parse/LibParseLiteralDiaKey.t.sol). The replacement must still emit V3 IntOrAString, or that test and the CLAUDE.md contract have to be revisited alongside it. Do not bump past that pin to chase a compiling build.

No empty-commit retrigger: the failure is deterministic and reproduces locally byte-identically to CI, so there is no transient signature to retry.
