114-126:⚠️ Potential issue | 🟠 MajorEnforce Zoltu factory codehash, not only code presence.
The flow currently checks only
ZOLTU_FACTORY.code.length. A non-empty but non-canonical factory can pass dependency checks, anddeployToNetworksdoes not re-verify the factory hash. SinceZOLTU_FACTORY_CODEHASHalready exists, this should be enforced in both phases.Suggested integrity check patch

In `@audit/2026-03-05-01/pass1/LibRainDeploy.md`:
- Around line 11-33: The markdown tables for the "Function" block (containing
deployZoltu, supportedNetworks, deployAndBroadcastToSupportedNetworks), the
"Errors" block (containing DeployFailed, MissingDependency,
UnexpectedDeployedAddress, UnexpectedDeployedCodeHash), and the "Constants"
block (containing ZOLTU_FACTORY, ARBITRUM_ONE, BASE, FLARE, POLYGON) need blank
lines inserted immediately before each table header and immediately after each
table ends to satisfy MD058; update the LibRainDeploy.md sections so there is an
empty line above the pipe-separated header row and an empty line after the
trailing table row for each of those three tables.
In `@audit/2026-03-05-01/pass2/LibRainDeploy.md`:
- Around line 11-33: Add blank lines before and after each Markdown table block
so they are separated from surrounding text: ensure the "Function" table
(containing deployZoltu, supportedNetworks,
deployAndBroadcastToSupportedNetworks), the "Errors" table (DeployFailed,
MissingDependency, UnexpectedDeployedAddress, UnexpectedDeployedCodeHash), and
the "Constants" table (ZOLTU_FACTORY, ARBITRUM_ONE, BASE, FLARE, POLYGON) each
have an empty line above and below the table delimiter rows to satisfy MD058.
In `@audit/2026-03-05-01/pass4/LibRainDeploy.md`:
- Around line 13-16: The report still references the removed function name
deployAndBroadcastToSupportedNetworks; update the document to reflect the
current API by replacing that symbol with deployAndBroadcast (and adjust any
parameter/signature text if necessary to match the new function's parameters),
and search for any other occurrences of deployAndBroadcastToSupportedNetworks in
the report to remove or rename so the function table and descriptions match the
library's current API.
- Around line 11-26: Add blank lines before and after each markdown table in the
report (e.g., the tables listing Functions, Errors, and Constants) so they are
separated from surrounding text, and update the fenced code block at the
deployAndBroadcastToSupportedNetworks example to include a language identifier
(for example ```solidity or ```bash) on the opening fence to satisfy
MD058/MD040; ensure the code fence that was at Line 86 is changed from ``` to
something like ```solidity and that surrounding tables have an empty line above
and below them.
In `@audit/2026-03-05-01/pass5/LibRainDeploy.md`:
- Around line 13-16: The report references the old function name
deployAndBroadcastToSupportedNetworks; update all occurrences to the current
function name deployAndBroadcast and adjust any referenced line-range/location
notes accordingly (including the table row and the sections noted at lines 68-75
and 97-107) so the documentation matches the code surface; ensure other symbols
like deployZoltu, supportedNetworks, and the signature format remain unchanged
while replacing the old function name and any dead links or cross-references
that point to deployAndBroadcastToSupportedNetworks.
- Around line 11-26: Add required surrounding blank lines before and after each
Markdown table (the Function, Errors, and Constants tables referenced by
`deployZoltu`, `supportedNetworks`, and `deployAndBroadcastToSupportedNetworks`)
and ensure the fenced code block at the indicated location includes a language
tag (e.g., `solidity`) and also has blank lines before and after the fence;
update the fenced block around lines 43-45 to start with ```solidity and end
with ``` with a blank line separating it from adjacent text so markdownlint no
longer flags the tables or fenced block.
In `@audit/2026-03-05-01/triage.md`:
- Line 34: Update the test coverage summary to use the renamed function name:
replace the reference to deployAndBroadcastToSupportedNetworks with
deployAndBroadcast in the triage.md entry so it matches the actual test file and
the mention at Line 52; ensure the summary lists deployAndBroadcast (happy path
+ NoNetworks) alongside the other tests and any related function names like
supportedNetworks, deployZoltu, checkDependencies, deployToNetworks remain
unchanged.
- Around line 21-52: Add a single blank line after each subsection heading (for
example "### P0-A01-1 — Missing foundry.toml", "### P0-A01-2 — CLAUDE.md
describes Zoltu as \"CREATE2-style\"", "### P1-A01-1 — Silent address(0) return
when networks array is empty", etc.) so that the subsequent "**Status:**" lines
are separated by one empty line; update every subsection from the P0/P1... list
to comply with MD022.
In `@CLAUDE.md`:
- Around line 42-46: Update the Architecture section to reflect the current
LibRainDeploy API: replace the old reference to
deployAndBroadcastToSupportedNetworks(...) with the new flow and function
names—describe checkDependencies (validates required artifacts/dependencies per
network), deployToNetworks (per-network deployment logic using deployZoltu(bytes
creationCode) and supportedNetworks()), and deployAndBroadcast (aggregates
results and broadcasts proofs); also mention the relevant errors/constants used
by these functions for failure modes. Ensure each function name
(checkDependencies, deployToNetworks, deployAndBroadcast, deployZoltu,
supportedNetworks) is referenced explicitly and the sequence of operations
(dependency check → per-network deploy → verification/broadcast) is clearly
described so the doc matches the current code.
- Line 10: Update the README/CLAUDE.md setup section to explicitly list the
required RPC environment variables for each supported network (e.g.,
RPC_URL_ARBITRUM, RPC_URL_BASE, RPC_URL_FLARE, RPC_URL_POLYGON or a documented
pattern like RPC_URL_<NETWORK>) and state the fallback behavior when they are
unset (e.g., use a default local RPC endpoint or abort with a clear error
instructing the user to set the env var). Reference the supported-networks
sentence (the rain.deploy description listing Arbitrum, Base, Flare, Polygon)
and add a short bullet or sentence giving the exact variable names, expected
formats (HTTP WebSocket), and what happens if a variable is missing. Ensure the
doc mentions any alternate config keys (like a single RPC_URL or a networks
config file) if the code supports them.
In `@foundry.toml`:
- Around line 11-13: The RPC endpoints block in foundry.toml only defines
arbitrum and base but must include endpoints for the other supported networks
declared in src/lib/LibRainDeploy.sol (constants ARBITRUM_ONE, BASE, FLARE,
POLYGON); update the [rpc_endpoints] section to add flare = "${FLARE_RPC_URL}"
and polygon = "${POLYGON_RPC_URL}" so fork selection and deployments can resolve
all four networks.
In `@slither.config.json`:
- Line 3: Remove the global "assembly" suppression from slither.config.json
(remove the detectors_to_exclude entry for "assembly") and instead add a scoped
suppression comment directly above the inline assembly in the deployZoltu
function in src/lib/LibRainDeploy.sol (use a slither-disable-next-line comment
at the assembly block around line 71) so that only that known assembly usage is
ignored and the assembly detector remains active elsewhere.
In `@test/src/lib/LibRainDeploy.t.sol`:
- Around line 265-266: Replace the generic vm.expectRevert() calls with
selector-specific expectations to ensure the test only passes for the intended
revert; specifically, before calling this.externalDeployToNetworks(...) use
vm.expectRevert(LibRainDeploy.DependencyChanged.selector) (and do the same for
the second occurrence around lines 283-284) so the test asserts the revert
raised is the LibRainDeploy.DependencyChanged selector rather than any revert.

Outside diff comments:
In `@src/lib/LibRainDeploy.sol`:
- Around line 114-126: The check that currently only verifies
ZOLTU_FACTORY.code.length must also enforce its codehash equals
ZOLTU_FACTORY_CODEHASH: update the block that logs and validates ZOLTU_FACTORY
to compare ZOLTU_FACTORY.codehash to ZOLTU_FACTORY_CODEHASH and revert
MissingDependency if it mismatches; do the same in the second occurrence (the
later validation block) and ensure depCodeHashes still records
dependencies[j].codehash. Also add the same codehash verification inside
deployToNetworks where the factory is re-validated so a non-canonical factory
cannot pass that phase either.

In `@audit/2026-03-05-02/pass0/process.md`:
- Around line 3-8: Add a blank line after the heading "## Documents Reviewed" so
the markdown has an empty line between that heading and the following list
(fixing MD022); update the section around the "## Documents Reviewed" heading in
audit/2026-03-05-02/pass0/process.md to ensure there is one empty line before
the list that starts with `- CLAUDE.md`.
In `@audit/2026-03-05-02/pass1/LibRainDeploy.md`:
- Around line 10-19: The markdown tables (e.g., the Functions table listing
etchZoltuFactory, deployZoltu, supportedNetworks, checkDependencies,
deployToNetworks, deployAndBroadcast) must be surrounded by blank lines to
satisfy MD058; edit the MD file to ensure there is an empty line immediately
before the table's first line (the one starting with "| Function") and an empty
line immediately after the table's last line, and apply the same change to the
other two table blocks referenced around lines 20-29 and 30-40 so each table is
isolated by blank lines.
In `@audit/2026-03-05-02/pass3/LibRainDeploy.md`:
- Line 4: Replace the environment-specific absolute path
'/Users/thedavidmeister/Code/rain.deploy/src/lib/LibRainDeploy.sol' in the audit
artifact with a repository-relative path (e.g., src/lib/LibRainDeploy.sol) so
the audit is portable; update any occurrences in
audit/2026-03-05-02/pass3/LibRainDeploy.md to reference the repo-relative path
instead of the local absolute path.
In `@audit/2026-03-05-02/pass4/LibRainDeploy.md`:
- Line 4: Replace the absolute local filesystem path
`/Users/thedavidmeister/Code/rain.deploy/src/lib/LibRainDeploy.sol` in the
Markdown entry with a relative repository path (for example
`src/lib/LibRainDeploy.sol` or `./src/lib/LibRainDeploy.sol`) so the reference
is portable; update the string in LibRainDeploy.md (the line that currently
contains the absolute path) to the chosen relative path and ensure any
surrounding documentation links or references still resolve correctly.
In `@audit/2026-03-05-02/pass5/LibRainDeploy.md`:
- Around line 16-25: The Markdown tables lack surrounding blank lines which
triggers MD058; edit LibRainDeploy.md to ensure each table block (for example
the Functions table listing `etchZoltuFactory(Vm)`, `deployZoltu(bytes memory)`,
`supportedNetworks()`, `checkDependencies(Vm, string[], address[], mapping)`,
`deployToNetworks(Vm, string[], address, bytes, string, address, bytes32,
address[], mapping)`, `deployAndBroadcast(Vm, string[], uint256, bytes, string,
address, bytes32, address[], mapping)` and the other table sections covering
lines 26-35, 36-45, 56-77) has a blank line immediately before and after the
table markdown so it conforms to MD058.
In `@CLAUDE.md`:
- Around line 40-47: The fenced code block showing RPC environment variables
(e.g., ARBITRUM_RPC_URL, BASE_RPC_URL, FLARE_RPC_URL, POLYGON_RPC_URL) in
CLAUDE.md should include a language identifier; update the opening fence to use
```bash (or ```env) so the block is labeled for proper rendering and
accessibility and leave the environment variable lines unchanged.
In `@src/lib/LibRainDeploy.sol`:
- Around line 140-142: Update the NatSpec for the function deployToNetworks to
state that the function is idempotent and may skip deploying to a network if
code already exists at the expectedAddress; specifically edit the comment block
for deployToNetworks to explain that after verifying dependencies the function
will check expectedAddress on each network and will not re-deploy if non-empty
code is found, and that callers can rely on this skip behavior as a safe no-op
rather than an error.
- Around line 99-104: Update the NatSpec for the function checkDependencies to
state that it verifies both that each dependency has code and that the Zoltu
factory's codehash matches the expected ZOLTU_FACTORY_CODEHASH; mention that it
records each dependency's codehash into the depCodeHashes mapping and verifies
the factory codehash exactly. Refer to the function name checkDependencies, the
constant ZOLTU_FACTORY_CODEHASH, and the storage mapping depCodeHashes so
readers know which symbols are involved and what the function guarantees.
