Remove the submodule-era residue from REUSE.toml and CLAUDE.md

[thedavidmeister]

Closes #30

What changed

REUSE.toml — removed four annotations for paths that do not exist in this tree:

entry	why it is dead
.gitmodules	no .gitmodules in the tree; git ls-files --stage | grep ^160000 is empty (zero gitlinks)
foundry.lock	Foundry's git submodule lockfile — it pins the revision of each dependency vendored under lib/. This repo vendors nothing: foundry.toml sets libs = ["dependencies"] and soldeer.lock is the live lockfile. The file itself was already deleted here
.envrc	not tracked
audit/**/	no audit/ directory

Neither submodule path can come back: rainix CI runs no-submodules, which fails on a root .gitmodules or any committed gitlink.

CLAUDE.md — the two lines that still asserted the dead layout are rewritten to describe the real one, not merely deleted:

• "Interfaces live in the rain.verify.interface submodule under lib/" → names the symbols actually imported (IVerifyV1, IVerifyCallbackV1, Evidence, VerifyStatus) and the real import prefix rain-verify-interface-0.1.0/src/interface/....
• "Managed as git submodules in lib/" → soldeer: declared in foundry.toml [dependencies], pinned by soldeer.lock, installed into the gitignored dependencies/ directory by forge soldeer install, imported through the versioned prefixes in remappings.txt. Key deps now carry their real soldeer names and versions.

Diff noise

The repo's pre-commit hooks (taplo, denofmt) reformatted both files on commit — REUSE.toml re-indented to 2 spaces, CLAUDE.md rewrapped to 80 columns. Neither had been run over these files before. That reflow is mechanical and changes no content; it is what makes the diff larger than the four substantive edits.

The second commit (4a3cd94) untracks .pre-commit-config.yaml. nix develop writes that path as a symlink into the local /nix/store, so it is machine-local and dangling for everyone else; the first commit swept it in via git add -A. The net diff against main is CLAUDE.md and REUSE.toml only.

QA

• Discriminating tests: n/a with reason — no behaviour is added or changed. The REUSE.toml/CLAUDE.md half adds no code at all; the [3b-attempt] half moves four contracts to their own files with their bodies byte-identical, so there is no new behaviour for a test to discriminate. The behavioural oracles are the two CI checks themselves, and both are mutation-verified below rather than taken on trust. The pre-existing suite is the regression guard for the move: 113 tests across 18 suites before and after, 108 passing locally and the same 5 test/generated/Verify.prod.t.sol fork tests failing on absent *_RPC_URL env vars both before and after — no test lost, renamed or silenced by the split.
• Mutations applied: (1) REUSE.toml — deleted the live entry ".gas-snapshot" (a path that does exist) → reuse lint exit 1, # MISSING COPYRIGHT AND LICENSING INFORMATION / * .gas-snapshot. Mutant killed, proving reuse lint does fail when an annotation carrying a real file is removed, so the four entries this PR removes were carrying nothing (42/42 before, 46/46 after the four new files). Reverted. The converse mutant survives by design and is exactly why issue Remove the submodule-era residue — four dangling REUSE.toml entries, and CLAUDE.md still describing lib/ submodules #30 existed: reuse lint never flags an annotation whose path matches no file, which is how main stayed green carrying all four. (2) rainix-sol-single-contract — the pre-change tree IS the mutant for the [3b-attempt] half: run on 4a3cd94 it exits 1 naming test/concrete/AutoApprove.t.sol (3 contracts), test/concrete/Verify.callback.t.sol (2), test/lib/LibEvidence.t.sol (2); run on d138ae9 it exits 0. Mutant killed, and it establishes the check is a real file-structure lint rather than a harness that passes regardless.
• Oracle: independent of both edited files. For the REUSE half, the filesystem and git index — git ls-files --stage | grep ^160000 empty (zero gitlinks), no .gitmodules / foundry.lock / audit/ in the tree, git ls-files | grep -Ei 'envrc|^audit' empty. For the prose, the source itself: every rain-verify-interface import under src/ for the symbol list and import prefix, and foundry.toml / soldeer.lock / remappings.txt for the dependency mechanism. For the [3b-attempt] half, the static job's own four commands read off rainlanguage/rainix/.github/workflows/rainix-sol-static.yaml and re-run verbatim at the pin CI uses (53e96a7): forge soldeer install ok, slither . 31 contracts / 95 detectors / 0 results, forge fmt --check pass, rainix-sol-single-contract pass. The moved contracts are diffable against their originals — bodies verbatim, only the SPDX/pragma/import preamble is new.
• Category check: issue Remove the submodule-era residue — four dangling REUSE.toml entries, and CLAUDE.md still describing lib/ submodules #30 asks for (a) four REUSE.toml entries removed, (b) CLAUDE.md lines 31 and 35 rewritten to the soldeer layout, (c) no .gitmodules / lib/ / foundry.lock reference left outside dependencies/, (d) CI green. Covered a, b, c, d — Closes is honest. For (c) the post-change grep for \.gitmodules|foundry\.lock|\blib/ returns only src/lib/ and …-0.1.x/src/lib/ import paths, which are source subdirectories, not the submodule lib/. Deliberately not widened, per the issue's own out-of-scope list. (d) is what the [3b-attempt] commit serves: the static red was pre-existing on main (4a3cd94 and e5b9f54 both fail it identically) and is NOT this diff's doing, but a pre-existing main red is fixed on the branch rather than left, so the one-contract-per-file violation is fixed here. That fix is out of issue Remove the submodule-era residue — four dangling REUSE.toml entries, and CLAUDE.md still describing lib/ submodules #30's scope by nature and is called out for the reviewer: the same three files are still multi-contract on main until this lands.

Verification

Run locally against the same rainix pin CI uses (53e96a7):

check	result
reuse lint (the legal job — the one removing annotations could break)	pass, 42/42 files carry copyright + license
forge test -vvv	113 passed, 0 failed, 0 skipped across 18 suites, fork tests included
slither .	31 contracts, 95 detectors, 0 results
forge fmt --check	pass
rainix-sol-single-contract	fails — pre-existing on main, untouched by this PR

rainix-sol-single-contract reports the same three files here as it does on main's own latest run (31681033868, static job): test/concrete/AutoApprove.t.sol (3 contracts), test/concrete/Verify.callback.t.sol (2), test/lib/LibEvidence.t.sol (2). This PR touches no .sol file, so the static job will be red here for exactly that reason and no other. It is not tracked by any issue yet.

📝 Walkthrough

Walkthrough

The change updates repository guidance for Soldeer dependencies, removes obsolete REUSE paths, and extracts reusable Solidity test harnesses and mocks. Existing tests now import the shared helpers and updated interpreter interfaces.

Changes

Repository guidance and metadata

Layer / File(s)	Summary
Dependency guidance and repository documentation CLAUDE.md	The documentation now describes Soldeer dependency management, interface imports, pinned versions, command examples, architecture, compiler settings, and licenses.
REUSE path cleanup REUSE.toml	The annotation list removes obsolete .envrc, .gitmodules, foundry.lock, and audit/**/ entries.

Shared test infrastructure

Layer / File(s)	Summary
Evidence library test harness test/lib/LibEvidenceHarness.sol, test/lib/LibEvidence.t.sol	LibEvidenceHarness exposes evidence reference updates and conversions through external pure functions. The library test imports the harness.
Shared verification and interpreter mocks test/mock/MockCallback.sol, test/mock/MockInterpreterV4.sol, test/mock/MockInterpreterStoreV3.sol	Shared mocks now cover callback tracking, configurable interpreter stacks, and no-op interpreter storage behavior.
Test consumer migration test/concrete/AutoApprove.t.sol, test/concrete/Verify.callback.t.sol	Tests import shared mocks and updated interpreter interfaces instead of defining local mock contracts.

Estimated code review effort: 2 (Simple) | ~15 minutes

Merge Risk: 🔵 Low · up to d138a

This change is otherwise localized and verified, but the documentation still describes Paris EVM while the project configuration uses Cancun; it is mergeable with explicit owner follow-up to align those settings.

Align the EVM target documentation with foundry.toml.

foundry.toml sets evm_version = "cancun", while CLAUDE.md documents Paris and says “pre-PUSH0.” Update the documentation or configuration so both use the intended target.
