… points Adversarial mutation testing at 5c165a8 found ten surviving mutants. Nine are the same shape: the inherited `rain-deploy` assertions check that a suite's recorded pins agree with its own creation code, and never ask about the declaration's METADATA — the suite key, the artifact path, the dependency list — none of which is derivable from a snapshot's bytes, and each of which steers something real. `CloneFactoryDeploySuitesDeclarationTest` asks: - Every frozen release directory is declared by a released suite under its own KEY. `testEveryFrozenSnapshotIsReleased` matches a record file to a release by the DEPLOYED ADDRESS it declares, so two releases that froze identical creation code are indistinguishable to it: dropping `0_1_10` from the declaration left `0_1_9` matching its record file and the whole suite green (mutant M45 SURVIVED), while dropping `0_1_1`, whose bytecode is unique, was caught (M46 KILLED). Same edit, opposite verdicts. - The candidate is declared under the bare `clone-factory` key. - `[external.package].version` has a frozen snapshot directory, the lockstep CLAUDE.md documents and nothing enforced. - Every declared suite records an EMPTY dependency list. The repo pinned this for the candidate's generated constant but not for the declaration, which is what the broadcast and the chain check actually read. - Every declared suite's `artifactPath` names a file that exists and the contract inside it. Nothing derives it, so a stale path survives every other assertion and fails after the gas is spent. `CloneFactoryCloneDeterministicOpenSaltTest` is the counterpart to `CloneFactoryCloneDeterministicTest`, which covers only the namespaced pair. Every expectation is built from the `ICloneableFactoryV4` spec and OpenZeppelin `Clones`, never from `LibICloneableFactoryV4`: the equivalence suite states its open-salt expectations in terms of the library's own `effectiveOpenSalt`, so it moves with the derivation rather than checking it, where the namespaced pair has had an independent oracle all along. It also covers the derivation's defining property — that the address is sender independent and commits to `data` — which nothing asserted directly. Revert paths and the `NewClone` event are deliberately not restated; the equivalence suite already holds them field for field. 28 tests -> 38.

rain-deploy deliberately refuses to compare the record's size against the declaration's, and says why on testEveryFrozenSnapshotIsReleased: a release deployed before a repo adopted the machinery has no frozen record and never will, so a size check red-lines that state permanently with no way to spell the exemption. Asserting it here reintroduced exactly that, for no gain — the per-tag key lookup is what kills a dropped release. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Match the declared contract name as an identifier.
vm.contains only checks file text. A declaration such as contract CloneFactoryV2 or a comment containing contract CloneFactory satisfies the assertion for CloneFactory. The declaration test can therefore miss a stale or incorrect <path>:<Name> target.
Use a Solidity-aware declaration check. If that is not practical, assert the supported artifact paths exactly and add regression cases for name prefixes and comments.

Picks up #39 (pre-commit formatter re-sync) and #40 (stale .gas-snapshot deletion), which is what `rainix-sol / static` was red on: this branch predates the REUSE.toml/.coderabbitai.yaml formatting fix and the job's `pre-commit run --all-files` step reformatted them on every run.

This PR carried three separable things. One PR per issue, so the other two move to their own branches off `main` and their own PRs: - `test/src/concrete/CloneFactoryCloneDeterministicOpenSalt.t.sol` closes no mutation gap (every concrete delegation mutant was already killed by the behaviour suite); it is oracle independence for the open-salt entry points and stands on its own issue. - `audit/mutation-test-scans.json` is campaign bookkeeping tied to no issue. What stays here is the one coherent unit: the five declaration-metadata tests, which close the nine Pass-A survivors that the inherited `rain-deploy` assertions cannot see. Neither removal touches the declaration suite; all three parts are independently mergeable. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

`rainix-static mutation-ledger` requires every SHA a record names to be an
ancestor of HEAD, and red-flagged this record on a branch off `main`:
ERROR: audit/mutation-test-scans.json[0].testsAfterCommit:
70d4e18 is not an ancestor of HEAD
That is correct and the record was wrong, not the gate. `70d4e18` is a commit on
the branch behind #37; it was an ancestor only while the scan record and the
tests shared one branch. Now that the scan record stands alone -- one PR per
issue -- no commit on this history carries those tests, so the field has no
truthful value here.
The field is optional by design: the gate validates `testsAfterCommit` when
present and never requires it, precisely so that a run whose test tree cannot be
named is not pushed into inventing a SHA. Its module doc is explicit that "the
only way to go green would be to invent a SHA, which is the fabricated evidence
this gate exists to catch."
So it is dropped rather than repointed. Everything the gate does require is
unchanged and valid: `commit` 5c165a8 is an ancestor of this branch, the
timestamp is well-formed, `tool` matches, and `scope`/`summary` are intact.

`vm.contains(vm.readFile(path), "contract <Name>")` is a substring match over file text: it is satisfied by the name in a comment, and by a longer declaration, so `contract CloneFactoryV2` satisfied it for `CloneFactory`. `vm.getCode` is forge's own resolution of a `<path>:<Name>` artifact id, the same form `forge verify-contract` takes. The file check stays because `vm.getCode` matches by path suffix. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
