Closes rainlanguage/rain.solmem#150

Removes audit/audits.json and the README.md link that pointed at it.
audit/mutation-test-scans.json and audit/protofire/ are untouched.

Everything that referenced the file

Checked rather than assumed, because two of these were the ones most likely to
break on a deletion:

Where Reference Action
README.md:77 a markdown link to audit/audits.json in the ## Audit section removed, see below
REUSE.toml covers audit/**/ as a directory glob, no per-file entry none — the directory still holds mutation-test-scans.json and protofire/, and nix develop -c reuse lint is compliant at 68/68 files after the deletion
.soldeerignore excludes /audit wholesale none
CI .github/workflows/rainix.yaml and package-release.yaml are uses: lines into the rainix reusables; at rainlanguage/rainix HEAD no reusable workflow mentions audit (the only audit string in that repo's workflows is npm --no-audit) none — there is no glob or gate to update
.audit/scope.json the audit skill's own scope snapshot, taken at 30ecd99 on 2026-07-25, predates the file and never listed it none
org-wide code search audits.json returns one hit in rainlanguage — the README.md line above — and zero across gildlab, cyclofinance, S01-Issuer, ST0x-Technology, ST0x-intelligence, h20liquidity, raincommercial, rain-archive none

After the change git grep -In audits over every tracked non-PDF file returns
nothing.

The one live thing that is about this file is not a code reference:
rainlanguage/rainix#321, still open, proposes a
rainix-sol drift-report job whose entire input is a consumer-side
audit/audits.json. Nothing there executes yet, so nothing breaks, but its
premise is gone — flagged, not edited, from here.

The README section

The section stays; only the pointer to the deleted file goes. The sentence that
carried the link stated the audited scope, so it is reworded to state the same
scope without the link rather than dropped:

Scope was all of src/ at those commits, the twelve contracts the report's
own scope table lists.

That claim is verified in this clone, not carried over from #137: at both
228b35c6725877e7fbcd2432b4c692357f16f510 and
26bce6197383f193e35326bab4d4424cf6eafde7, git ls-tree -r --name-only <c> -- src/ is exactly twelve files, and both commits are ancestors of HEAD.

What #88 needs now

Nothing in this repo, and it should stay closed.

rainlanguage/rain.solmem#88 is a MEDIUM audit finding
whose hazard is "nothing in the repo records which commit was audited or that
main has moved past it". After this PR the record is still there, in the
## Audit section of README.md: it names both reviewed commits, links the
report PDF — which nothing else in the repo did before #137 — states the
audited scope, says outright that today's src/ is not that tree, and gives the
command that measures the drift. What this PR deletes is a second, machine-only
copy of that record with no machine reading it.

The part of #88 that is genuinely unlanded is its third ask, the non-blocking CI
drift report. That was never in this repo's gift — its CI is two uses: lines
into rainix reusables — and it lives as
rainlanguage/rainix#321. That issue is the one that
needs a decision, and it needs it independently of #88: as written it reads a
manifest that now exists nowhere, so it is either re-scoped to derive the
audited commit from something that does exist, or the manifest is reintroduced
deliberately as an org-wide convention with the reader landing in the same
change, or drift reporting is dropped. Reintroducing it here first would
recreate exactly the file #150 removes.

Not reopened or edited by this PR, per the work order.

QA

  • Discriminating tests: n/a as forge tests — the diff is one deleted JSON file
    and two reflowed README lines, no Solidity, and a test asserting a path's
    absence would be the same unread ceremony this PR removes. The three
    discriminating checks, each failing on a mutant and passing here: A
    git grep -In "audits" -- . ':!*.pdf' — 1 hit on main (README.md:77), 0
    on this branch
    ; B git ls-files audit/ — must still list
    mutation-test-scans.json and the Protofire PDF, 2 entries on this
    branch
    ; C nix develop -c reuse lintcompliant, 68 / 68 files
    (69 / 69 on main, the difference being the deleted file itself).
  • Mutations applied: M1 restore main's README.md and
    audit/audits.json -> check A goes 0 hits -> 1 hit, README.md:77 -> killed.
    M2 also git rm audit/mutation-test-scans.json -> check B goes 2 entries
    -> 1 entry -> killed; this is the overreach Toggle big blocks from an admin-gated manual workflow #150 explicitly forbids, and it is
    the mutant worth having. M3 delete the "audit/**/" glob from
    REUSE.toml, on the theory that a per-file entry was what covered the deleted
    file -> check C reports not compliant, 66 / 68, the two surviving audit
    files losing their licence -> killed, which is why REUSE.toml is unchanged
    here. The three checks move independently across the mutants — 0/1 hits,
    2/1 entries, 68/66 files — so they ran rather than matching nothing.
  • Oracle: Remove audit/audits.json: invented today, read by nothing, already stale rain.solmem#150 for what must
    go and what must stay; the Protofire report and git for the scope sentence
    that replaces the link — the twelve files were re-derived here with
    git ls-tree -r --name-only <commit> -- src/ at both review commits, not
    taken from Point the generated-lib writers at a directory they are handed #137's body.
  • Category check: the issue asks A remove audit/audits.json, B remove the
    README.md line pointing at it, C leave audit/mutation-test-scans.json and
    audit/protofire/ alone. Covered A, B, C. Its fourth paragraph — "reopen or
    replace ci: daily scheduled sol sweep so chain drift is caught without a push #88 if the drift it names is still worth tracking" — is answered in
    words above and deliberately not acted on, per the work order.

QA

  • Discriminating tests: LibRainDeployTest.testSupportedNetworks (the roster
    and its order), LibRainDeployTest.testSupportedNetworksAreFullyConfigured
    (supportedNetworks() against both foundry.toml sections, both
    directions), LibRainDeployTest.testZoltuFactoryCodehash (forks every
    supported network and reads the factory on it) — the first two each fail
    under a mutation that reverts one half of this diff, shown below; the third
    passes on seven forks, which is the only thing that says the two new
    [rpc_endpoints] aliases resolve and the Zoltu factory is live with its
    expected codehash on Ethereum and HyperEVM. Verified by running
    nix develop -c forge test --match-contract LibRainDeployTest --match-test 'testSupportedNetworks|testZoltuFactoryCodehash' → 3 passed, 0 failed.
  • Mutations applied:
    • foundry.toml [etherscan] hyperevm line deleted → killed by
      testSupportedNetworksAreFullyConfigured.
    • foundry.toml [rpc_endpoints] ethereum line deleted → killed by
      testSupportedNetworksAreFullyConfigured.
    • foundry.toml extra [etherscan] optimism key no network names → killed
      by testSupportedNetworksAreFullyConfigured (the reverse direction).
    • networks[5] = HYPEREVMPOLYGON, keeping the length at seven → killed
      by testSupportedNetworksAreFullyConfigured.
    • networks[3]/networks[4] swapped, ETHEREUM after FLARE → killed by
      testSupportedNetworks (assertion failed: flare != ethereum), and
      SURVIVED testSupportedNetworksAreFullyConfigured, which asserts membership
      rather than order — the two tests are not redundant.
    • ETHEREUM = "ethereum""mainnet" → killed by
      testSupportedNetworksAreFullyConfigured
      (supported network has no [rpc_endpoints] alias: mainnet).
    • HYPEREVM = "hyperevm""hyperliquid" → killed by
      testSupportedNetworksAreFullyConfigured
      (supported network has no [rpc_endpoints] alias: hyperliquid).
  • Oracle: every value here comes from outside this repo's source. Chain ids and
    env var names are rainix's NETWORKS table in
    rainix-static/src/rpc_preflight.rsethereum is chain 1 reading
    ETHEREUM_RPC_URL, hyperevm is chain 999 reading HYPEREVM_RPC_URL. The
    --chain spellings are foundry's own parser, which rejects ethereum,
    hyperevm and base_sepolia and names mainnet, hyperliquid and
    base-sepolia in the rejection. The HyperEVM verifier is Etherscan's V2
    chainlist endpoint. Which chains already hold the Zoltu factory and
    AddressRegistry is cast code against the live chains, not anything the
    repo records.
  • Category check: the ask is (a) both chains in supportedNetworks(), (b)
    [rpc_endpoints] and [etherscan] in lockstep, (c) every other place the
    set is enumerated, (d) the secret names, by name, (e) whether HyperEVM has an
    Etherscan-family verifier. Covered a, b, c, d, e. One enumeration site carries
    no test: the networks default in manual-sol-verify.yaml. Nothing reads it
    — it is a workflow_dispatch default — and asserting it would need a second
    hand-written alias-to-chain-name mapping in the test, since three of the seven
    differ, which is one more enumeration of the set rather than one fewer.

Summary by CodeRabbit

  • New Features
    • Added support for Ethereum and HyperEVM networks.
    • Added RPC endpoint configuration for both networks.
    • Expanded deployment and verification coverage to seven supported networks.
  • Documentation
    • Updated deployment and verification guidance to reflect the expanded network coverage.
  • Tests
    • Updated network coverage checks to include Ethereum and HyperEVM.

`supportedNetworks()` goes from five to seven, and `[rpc_endpoints]` and
`[etherscan]` in `foundry.toml` move with it — the three lists are one
list and `testSupportedNetworksAreFullyConfigured` asserts it in both
directions.

The two new `[etherscan]` entries state `chain` because foundry does not
resolve `ethereum` or `hyperevm` to a chain by alias, and an entry with
neither `chain` nor `url` under an alias it cannot resolve fails the
whole section rather than only itself.
