+## Audit
+
+This repo has never been audited under its own name. It carries three
+**inherited** Protofire reports: audits of `rain.factory`, performed before the
+split, of the source that built the snapshots pinned here. They are prefixed
+`inherited.` and their provenance and per-snapshot coverage are recorded in
+[`audit/protofire/inherited.json`](audit/protofire/inherited.json) — read that
+file, not this section, for what each report covers.
+
+Every snapshot in `src/generated/` is covered by exactly one of them:
+`src/generated/0_1_3/` and `src/generated/0_1_4/` (the `ICloneableFactoryV2`
+bytecode) by r2.0, and `src/generated/0_1_5/` (the `ICloneableFactoryV3` rewrite
+that `LibCloneFactoryDeploy` currently aliases and that is live on every
+supported chain) by r3.0, which audited `rain.factory` at tag `sol-v0.1.5` with
+zero findings at every severity. Coverage is never inferred from a filename: it
+is asserted per snapshot directory in the manifest, so a future snapshot appears
+as uncovered until a report is inherited for it.

Zero findings at every severity. Coverage of src/generated/0_1_5 is an identity, not a rebuild: src/generated/0_1_5/CloneFactory.pointers.sol at that audited commit is byte-identical to this repo's copy (sha256 d3def164d01d2b50ebf7175a4efaaa76bfc020f992a9ed73e67203d3a54ed902), so the audited tree and this snapshot pin the same address 0x7053c1D000192f1FeC1fbe20350139F3300dBBaD and the same codehash.
