Address registry: interface, concrete, reader lib and post-deploy cross-network verification

[thedavidmeister]

Closes #25 and
#27. Supersedes
rainlanguage/rain.factory.deploy#7, which held the
concrete before it moved here.

Two issues, one structure. #25 wants a deployment to acquire a configured
address without baking one into creation code. #27 wants deploy pins verified
against source and against every chain, from an abstract every deploy repo
inherits rather than assertions hand-enumerated per version and per repo. What
both landed on is the same property: a repo declares what it deploys ONCE, and
the broadcast and every verification group read that one declaration. Nothing
here is written twice, nothing is written per network, and a suite is an array
entry.

The registry

src/interface/IAddressRegistryV1.sol and src/concrete/AddressRegistry.sol.
An immutable root binds an opaque bytes32 name to an address (register),
anyone reads a bound name (get), and reading an unbound name reverts. Three
errors, one event, two functions. No removal, no upgrade, no authority besides
root — root is a compile-time constant, so it cannot even hand itself over.

src/lib/LibAddressRegistry.sol is the read: resolve(bytes32 name) verifies
the registry's code hash before calling it, exactly as LibRainDeploy verifies
ZOLTU_FACTORY_CODEHASH. It resolves a name to an address and stops there. It
sets no owner and knows nothing about Ownable, roles or initializers.

Bindings are mutable, and that is the point. The name a consumer resolves is
in that consumer's creation code, so a write-once binding cannot express an
ordinary rotation of an owning Safe: it would need a new name, hence new
creation code and a new deterministic address — the exact problem the registry
exists to remove, relocated. Write-once also bought less than it looked like it
did. It protected bindings on chains already in use from a compromised root and
never protected a fresh chain, because an attacker who is root binds the name
there first either way.

Mutability costs nothing already deployed, because a consumer resolves once,
in its constructor, and stores the answer. MockResolvedOwner is that shape and
testCheckResolvedAddressesUnaffectedByRebinding is the proof: re-bind the name
after deploying, and the registry answers differently while the deployed
contract does not move.

Kept: immutable root, revert on unset, and register rejecting the zero
address. That last one still matters — unset reads as zero, so a zero binding
would be a name both bound and unreadable, and
testRegisterZeroAccountCannotUnbind pins that there is no way to unbind.

ADDRESS_REGISTRY_ROOT is address(0), deliberately. Nothing calls from
the zero address, so no name can be bound while root is zero, and get reverts
on every unbound name — a registry compiled under this root answers every read
with a revert and cannot answer one with an address. There is no state in which
a consumer silently resolves something wrong from it. That makes the zero root
inert rather than unfinished, which is what lets the deployment pattern ship
now. Setting a real root later is an ordinary source change that moves the
creation code, the address, the code hash and the snapshot together.

The check runs after the deploy

A pre-deploy check against a mutable registry is TOCTOU and guarantees nothing:
the binding can move between the check and the constructor that consumes it. So
LibRainDeploy.checkResolvedAddresses{,OnNetworks} run after the deploy,
against the value the deployed contract has already snapshotted — settled state
that cannot move underneath the check. A network where the deployment took
something else is a burned deterministic address, found while nothing points at
it yet.

Only the consumer knows where it stored what it resolved, so the consumer
supplies the reads (abi.encodeCall(IOwnable.owner, ()) and the like) and this
library supplies the fork loop and the comparison. It is deliberately
source-agnostic: it asserts that the deployed contract holds the expected
address, not where that address came from. Re-reading the registry here would
assert a value that can move rather than the value the deployment actually took.

Stated as a guarantee: on every listed network, target answers each supplied
read with exactly the expected address; a read that reverts, that hits an
address with no code, or that answers anything other than one address-sized word
is a failure, never a pass.

That last clause got stricter in the head commit. The read used to decode with
abi.decode(returnData, (address)), which validates the upper 96 bits itself
and reverts with no return data of its own. So a contract answering with one
word that is not an address — a getter declared bytes32 or uint256, or one
written in assembly — produced a bare revert naming neither the network, the
target, nor which read produced it, which is precisely what
ResolvedAddressReadFailed exists to avoid. It now decodes as a word, range
checks against type(uint160).max, then narrows.
testCheckResolvedAddressesDirtyWordReverts fuzzes over words that are not
addresses and expects the expected address to be that word's own low 160 bits,
so it rules out both wrong answers at once: truncating silently passes against
an address the read never gave, and decoding as an address reverts
undiagnosably.

One declaration, deployed AND verified

src/abstract/RainDeploySuitesBase.sol is the whole of what a deploy repo
writes. A DeploySuite is a key, the creation code, the recorded
address/code hash/runtime code, an artifact path, and the addresses that must
already be on chain before it can be broadcast. A DeployCandidate is one of
those plus the type(X).creationCode it must equal.

abstract contract AddressRegistryDeploySuites is RainDeploySuitesBase {
    function releasedSuites() internal pure override returns (DeploySuite[] memory);
    function candidateSuite() internal pure override returns (DeployCandidate memory);
}

contract Deploy is AddressRegistryDeploySuites, RainDeployBroadcast {}
contract AddressRegistryDeploySnapshotTest is AddressRegistryDeploySuites, RainDeployVerifySnapshot {}
contract AddressRegistryDeployChainTest is AddressRegistryDeploySuites, RainDeployVerifyChain {}

All three bodies are empty. The property is not that the deploy script and the
tests are checked to agree — it is that they cannot disagree, because there is
one array and all three read it. A repo that declared its suites twice, once for
the script and once for the tests, could broadcast one contract while verifying
another and stay green forever. That bug is not available here.

A registry, not an if. Suites are an array the abstract iterates. Adding
one is adding an entry; the valid keys a mistyped DEPLOYMENT_SUITE reports are
built from that same array, so the message cannot fall behind the suites;
duplicate keys revert in allSuites(), which both sides go through. Every suite
is individually selectable, including a frozen release — which is how a snapshot
from before a network existed reaches that network, and which is #27's open
question in operable form.

src/abstract/RainDeployBroadcast.sol is the broadcast: resolve the suite, then
read DEPLOYMENT_KEY, then deployAndBroadcast. In that order deliberately, so
a mistyped suite: input fails in seconds naming the valid ones rather than
failing on a missing key and sending the reader after the wrong thing.
deployNetworks() defaults to supportedNetworks() and is virtual, because
that default is not universal — a repo bootstrapping one chain per dispatch
(st0x.deploy selects between Ethereum and HyperEVM) overrides it, and the
reusable workflow already carries a network: input for exactly that.

What is deliberately NOT derived. The recorded address and code hash are
passed to deployAndBroadcast, not derived from the creation code there. They
are derivable — that is what RainDeployVerifySnapshot derives them for — but
deployToNetworks compares the recorded address against the creation code
before it forks anything, precisely so a stale pin fails instead of silently
deploying wherever the code lands. Feeding it a derived value makes that
comparison derived-against-derived, and a guard that compares a value to itself
is not a guard. The artifact path is declared for the same class of reason:
src/concrete/<Name>.sol:<Name> holds only for the flattest repos, and
st0x.deploy groups six of its ten concretes under deploy/ and authorize/.

Verification: four groups, sorted by what each is anchored to

The creation code is the only parameter. The Zoltu factory is CREATE2 over its
calldata under a zero salt, so the address is a pure function of it and
identical on every network, and running it once locally yields the runtime code
and its hash. Everything else a suite records is a checked OUTPUT.

RainDeployVerifyBase is the derivation, once: zoltuAddress for the address,
an actual deploy through the etched factory bytecode for the code hash, and the
two cross-checked against each other so a formula that drifted from the factory
is caught here rather than poisoning every comparison downstream. It runs inside
a state snapshot it reverts, and clears the derived address and its nonce first,
so it reads only what the creation code produces. A failed revert is
unrecoverable rather than a warning to silence —
DerivationSnapshotRevertFailed — because the etch would otherwise survive into
every later derivation, and the chain group would then compare a locally planted
deployment against itself.

group	anchored to	catches	cannot catch
internal	the recorded set	an inconsistently generated set — a hand-edited constant, a snapshot regenerated for one field, an address copied from the wrong tag	a snapshot of the wrong contract
source	type(X).creationCode	a snapshot of the wrong contract	anything about any chain
record	the frozen src/generated/<tag>/ tree	a release the declaration missed	what a declared suite records
chain	the networks	never deployed there, or not there any more	anything about the candidate

The first three are RainDeployVerifySnapshot and need no network. The fourth
is RainDeployVerifyChain and is the only thing here that forks.

The internal group's blind spot is not a gap to close there. Every check in it
asks the recorded bytes to agree with each other, and a consistent snapshot of
the wrong contract does that perfectly.
testWrongContractSnapshotPassesInternalConsistency pins the miss and
testWrongContractSnapshotCaughtBySource pins the catch, on the same fixture.

Two exemptions, and they are the same shape from opposite ends. The source
anchor is candidate-only, because a released tag is MEANT to have diverged from
current source. The chain group is released-only, because a candidate is what
the NEXT release will be and is ordinarily ahead of anything on chain — a repo
whose source has moved since its last deploy is the normal state of a repo, not
a fault in it. Neither is a field a caller can set: sourceCreationCode lives
on DeployCandidate and is simply absent from DeploySuite, and the chain
matrix takes releasedSuites() rather than allSuites(). There is no way to
spell "released, and also skip the checks that do apply", and no way to spell
"candidate, and please demand it be live".

The record group is what makes the chain group's scope complete, and it is
the one check here that is about the DECLARATION rather than about what a
declared suite records. Scoping to releases puts the whole weight on
releasedSuites() naming every release — and a frozen tag it does not name is
not an entry that turns up missing somewhere. It is a release the chain group is
never handed, and a check with no subject cannot fail on it, so that release
drops out of everything while the whole suite stays green. So every file in the
append-only src/generated/<tag>/ tree must be declared by a released suite.

The match is by address: the address a record file DECLARES against the
address a released suite's creation code DERIVES. Matching by name would assert
only that a convention was followed. Matching by searching the file's text would
be worse than useless — a record is two hex payloads thousands of digits long,
and an address that merely occurs somewhere in one says nothing about what the
file records. testFrozenSnapshotMatchesTheDeclarationNotTheText builds a
record that declares one address and merely mentions another, and
testFrozenSnapshotIgnoresACommentedOutDeclaration builds one whose declaration
is preceded by a commented-out copy carrying a released address — the parser
reads the declaration the compiler would read, because a parser that swallowed
the comment would let a hand edit park a released address above a real
declaration carrying something else. A file with no DEPLOYED_ADDRESS
declaration at all is FrozenSnapshotUnreadable rather than
FrozenSnapshotNotReleased, because reporting it as undeclared would send the
reader to releasedSuites() to add an entry for something that is not a
snapshot.

Chain-independent runtime code is a requirement, not a caveat. One recorded
code hash per suite can only be true if the runtime code is the same everywhere.
A constructor reading block.chainid deploys different code per chain —
deploying through Zoltu buys address predictability and such a constructor
spends it. So a per-chain difference is a DEFECT: it fails hard with
CodeHashMismatchOnNetwork(network, suite, address, expected, actual), naming
the chain and both hashes. There is deliberately no per-chain code hash to
record.

The split is by contract, not by naming convention.
RainDeployVerifySnapshot and RainDeployVerifyChain are separate abstracts, so
forge test --no-match-contract Chain is the whole snapshot gate and nothing
reachable from a snapshot contract forks anything. A contract is what
forge test and a CI job select at. It does not make the repo RPC-free — 26
tests in LibRainDeployTest fork, and always have — but it does mean an
unreachable endpoint can never fail an assertion that needed no endpoint.

The record: two facts, two homes

• src/generated/candidate/ — the ROLLING snapshot, regenerated every build,
  always describing HEAD.
• src/generated/<tag>/ — a FROZEN record of what a release deployed, written
  once and never again.

LibAddressRegistryDeploy aliases candidate, so consumers' import path never
moves. This is what makes the source anchor real for the first time: the
candidate's creation code is now RECORDED, so RainDeployVerifySnapshot
compares it against type(AddressRegistry).creationCode and catches a source
edit made without regenerating. While nothing was recorded, that check compared
source against itself and could only pass.

src/lib/LibAddressRegistryReleased.sol is the declaration of the frozen
record, and it is GENERATED from that record — by the same call that writes it.
Today it declares an empty set, because nothing has been released; the rolling
candidate is not a release. Four fields per entry are aliased from the release's
own frozen file, so the consensus record is read from the immutable file and
nowhere else. Three — the key, the artifact path, the dependencies — are
explorer and ordering metadata regenerated from the CURRENT declaration, which
means moving a source file retroactively updates the artifact path of a release
cut years ago. That is intended: the alternative is parsing the previously
generated Solidity back in to preserve what it last said.

Generating the record and the declaration of it from one call is what makes the
record group pass by construction rather than by remembering. The check still
earns its place, because it catches the three ways they come apart anyway: a
hand edit to the generated file, a record directory that arrived out of band,
and a generated file nobody regenerated after the record moved. Nothing in CI
regenerates anything, so a stale generated file is caught there or not at all.

The release ordering is structural

LibRainDeploySnapshot.freeze takes the regeneration as an argument and runs it
FIRST, in one call. cutRelease() is the only way to freeze, and it cannot
freeze anything it did not just generate — so "freeze, then regenerate" has
nowhere to be written. That is the property rainix#302 implements in Rust at the
CI layer; here it is in the Solidity consumers already depend on.

Every guard runs, and every byte that will be written is in hand, BEFORE
<tag>/ is created. That ordering is load bearing rather than tidy: filesystem
cheatcodes are not undone by a revert, so a throw once the directory exists
leaves a partial record behind — and a partial record IS a frozen tag, which
SnapshotAlreadyFrozen then refuses the retry of. The only exit would be
deleting a directory this design calls append-only, so a failure would wedge the
release rather than merely stop it. The guards: strict X.Y.Z (a 0.1.7-rc1
maps to a directory the append-only gate ignores forever — an orphan nothing
protects), this release not already frozen, the release naming at least one
contract, and every named contract having a rolling snapshot once regenerated.
Byte-identity of the frozen copy is true by construction — it is the bytes just
written, read back — so a diff -r afterwards would be redundant rather than
reimplemented.

One shape rule, asked twice. isStrictTriple is asked with . for a version
out of foundry.toml and with _ for the directory that version freezes to, so
what tagForVersion accepts and what the record walk recognises as a release
cannot drift apart. candidate/, a scratch directory and a 0_1_7-rc1 nobody
could have frozen all fall out under that same rule, and there is no name to
remember to exclude.

cutRelease() is wired: package-release.yaml's snapshot-generate-cmd is
forge script ./script/Build.sol --sig "cutRelease()" && forge fmt.

.pointers is gone, and LibSnapshot moved in

Pointers meant the interpreter's function-pointer tables. A file holding a
deploy address, a code hash and bytecode has none, so the name was a misnomer
carried by inertia. No .pointers string survives anywhere in this PR.
rain.deploy is the cheapest place in the org to make that change, because
src/generated/ did not exist here; every other repo has committed generated
files, some inside append-only frozen directories where a rename reads to the
append-only gate as modifying a frozen record. That migration is not in this PR.

LibSnapshot moved out of rain.sol.codegen and into
src/lib/LibRainDeploySnapshot.sol. "Which release am I building", "where does
its record live" and "freeze it immutably" are release machinery, not code
generation — splitting them across two repos was the reason nothing adopted it.
It had zero callers anywhere, so the move cost nothing, and it is deleted
upstream in rainlanguage/rain.sol.codegen#33 independently in both directions.

Ends on rain-sol-codegen 0.1.6. 0.1.5 is that deletion; 0.1.6 makes
filePrefix() generic — it no longer bakes in a consumer's script filename, and
no longer hardcodes a paragraph explaining that the file is committed because of
a circular dependency between a contract and its generated file, which is true
of a snapshot and false of an alias lib. Both writers here now use it, so
nothing restates SPDX lines and nothing emits a false statement into generated
output.

The alias lib is emitted once, not copied per repo

script/Build.sol hand-rolled ~20 lines of vm.writeLine for
LibAddressRegistryDeploy. rain.factory.deploy's LibCloneFactoryDeploy is
that shape to the character, so it was a precedent for copy-and-drift across
every deploy repo. It is now
LibRainDeploySnapshot.writeAliasLib(vm, contractName, constantPrefix, dir).
The library name and output path are DERIVED, because Lib<Contract>Deploy at
src/lib/ is mechanical; the constant prefix is PASSED, because deriving
ADDRESS_REGISTRY from AddressRegistry is camelCase-to-SCREAMING_SNAKE in
Solidity — a byte loop with an acronym problem — to save a caller one short
string.

The snapshot writer has one output root

LibFs.pathForContract hardcodes src/generated/ and takes a contract name
rather than a path, so writeSnapshot folds the snapshot directory into the
name it hands over and writes nowhere else. There is no staging, no copy and no
removal: an earlier round reached a non-default root by generating under
src/generated/ and moving the result, which is a recursive removal inside the
one tree that is supposed to be append-only. A test that wants a record tree of
its own writes it with vm.writeFile and reads it with frozenSnapshotPaths,
which DOES take a root — because reading somebody else's tree is a thing a walk
genuinely does, and writing this repo's record somewhere else is not.
LibRainDeploySnapshotTest builds its fixture under test/generated, never
src/generated, because the inherited record check reads that root from
contracts forge runs in parallel — a fixture release there would be one they
have to fail on for as long as it exists.

The assertions are the specification of a snapshot

Every deploy snapshot here is generated and committed. No hand-maintained hex
survives anywhere in the repo; a compiler or optimiser change is "run the
script, commit".

GeneratedSnapshotShapeTest states what a snapshot must be, once, in test code,
and checks it against the compiler's AST. No second reference file, so no
provenance to defend; no source-text matching, so formatting cannot break it.

1. exactly four constants, in order — bytes32 BYTECODE_HASH,
   address DEPLOYED_ADDRESS, bytes CREATION_CODE, bytes RUNTIME_CODE
2. every declaration is constant
3. no ImportDirective — a snapshot is read by repos that do not have the
   contract it describes, which is the whole reason a frozen release stays
   verifiable after its source has changed or gone
4. no ContractDefinition — it is a record, not code
5. the generated-file header is present

Values are deliberately not asserted: a solc change moves every literal without
changing the shape, and a wrong literal is caught immediately by the internal
group. Two things worth recording about the route: foundry emits an artifact for
a file declaring only file-level constants and no contract at all, which is what
makes this possible, and its JSON path support rejects a
$.ast.nodes[*].nodeType wildcard (a path must resolve to exactly one value),
so nodes are indexed one at a time under vm.keyExistsJson. ast = true in
foundry.toml puts the AST in the artifacts a plain forge test produces.

That shape is also what RainDeployVerifySnapshot relies on to read a record
from disk. It reads the text rather than the AST there, because a record is
reached by its PATH — which is what the record walk returns — while its artifact
path is not something a caller can name, since foundry disambiguates those by
whatever else happens to share the basename.

The concrete, the pins and the settings live together

The address and code hash are a function of the creation code, which is a
function of the compiler settings that compiled it. With the concrete, the
settings and the pins all in this repo there is no boundary across which they
can silently diverge, and nothing depends on rain-factory-deploy to get them.
foundry.toml pins solc = "0.8.25", optimizer_runs = 100000 and
evm_version = "cancun" exactly, so the pins cannot move under a compiler or
default-target change.

• ADDRESS_REGISTRY_DEPLOYED_ADDRESS = 0x25aC2b82915f191dbE64e65BAeDDD68b97b68fe1
• ADDRESS_REGISTRY_DEPLOYED_CODEHASH = 0xef835570415a69bdf98ea5cacd8c4d2caba4730d06c2218bf102cb4473f4ea73

Both generated, both aliased from src/generated/candidate/AddressRegistry.sol,
and both checked in-repo by AddressRegistryDeploySnapshotTest. They move if
the root constant changes, which is the point of the root being a constant.

Placement. All of the machinery is in src/, not test/. Two reasons and
the second is the one that matters: .soldeerignore excludes test/ from the
published package, so an abstract under test/ is unimportable by every
consumer that would inherit it — and this repo's PRODUCT is the deployment
process, so machinery for deploying and verifying deployments is not scaffolding
that happens to live here. CLAUDE.md records this as a SCOPED exception with
the explicit instruction not to copy it into a consumer repo, where src/ is
the product and deploy verification is scaffolding around it, so test/src/**
mirrors src/** unchanged. src/concrete/AddressRegistry.sol is an ordinary
deployed contract tested from test/src/concrete/ exactly as the convention
requires.

Slither. slither.config.json filters the six deploy/verify/suite abstracts
by exact filename. They are inherited by test contracts and never deployed, so
every detector is about a risk they do not have; the ones raised were "an
abstract does not implement its own virtuals" and "a cheatcode is called in a
loop". By name rather than by the src/abstract/ prefix, so a deployable file
added there later is still analyzed.

detectors_to_exclude is now assembly alone. The head commit removed
low-level-calls from it: one deliberate staticcall had silenced the detector
repo-wide, including for AddressRegistry. It is now a
// slither-disable-next-line low-level-calls at the site, so a value-bearing
call added anywhere else is still reported.

The deploy this repo had no way to run

AddressRegistry had pins, a generator and chain verification, and nothing that
could put it on chain — script/ held only Build.sol.

• script/Deploy.sol — contract Deploy is AddressRegistryDeploySuites, RainDeployBroadcast {}, empty body. Broadcasts whichever suite
  DEPLOYMENT_SUITE names, to every network in supportedNetworks().
• .github/workflows/manual-sol-artifacts.yaml — workflow_dispatch only,
  calling rainix-manual-sol-artifacts@main with suite: address-registry and
  secrets: inherit. Broadcasting is key custody and real money; no merge and
  no tag should be able to reach it.

The order is deploy → verify → tag, and they are three different things.
rainix-tag-release verifies live chains against freshly generated pins and
never broadcasts, which is exactly why the deploy cannot be folded into it.
Deploying is idempotent — deployToNetworks skips a network that already has
the code — so a partial run is fixed by running it again.

rainix-manual-sol-artifacts passes --verify by default and exports
CI_DEPLOY_<NET>_ETHERSCAN_API_KEY per network, but foundry.toml had no
[etherscan] section, so a dispatch would have broadcast and then failed with
no API key configured — after spending the gas. That section is added, one entry
per [rpc_endpoints] alias.

Nothing was dispatched and nothing was broadcast. The mechanism is added,
not run; the on-chain deploy follows the merge.

Release lifecycle: autopublish → tag release

This repo now carries a deployed concrete whose pins consumers rely on, which is
what rainix-tag-release exists for and what rainix-autopublish's
merge-driven, next-version lifecycle is wrong for: autopublish bumps
[package].version on every merge while a frozen deploy tag only advances at
deploy time. package-release.yaml moves to rainix-tag-release,
[package].version becomes the LAST released version (0.1.5), and
cutRelease() is the snapshot-generate-cmd.

Switching retracts nothing — every published version stays published and
consumers pin exact versions. It changes who cuts a release, not how anyone
consumes one.

script/BuildPointers.sol → script/Build.sol, per
rainlanguage/rainix#304. Eight org repos already use
Build.sol against four using the variant, and this PR would have made it five.
#304's larger half — folding generation into build — is deliberately not here.

What is red, and what it is not

The test job fails. Two tests of 130, both
[FAIL: vm.createSelectFork: ... HTTP error 500 ...] on the Arbitrum endpoint:
RainDeployVerifyChainTest::testChainMatrixReachesTheLastSupportedNetwork and
RainDeployVerifyChainCandidateTest::testChainIgnoresAnUndeployedCandidate.
That is an RPC outage, not an assertion — every assertion in the run passed, and
legal and static are green.

AddressRegistryDeployChainTest::testSuitesLiveOnEverySupportedNetwork
passes, at 547 gas, and that is correct rather than a hole. It checks
releasedSuites(), which is empty until the first release is frozen, so it has
no subject and forks nothing. An earlier round of this PR did demand the
candidate be live and was permanently red; that was the design being wrong, not
the report being wrong. Demanding a candidate be on chain makes every deploy
repo red for as long as its source is ahead of its last deploy, which is most of
them, most of the time. testChainIgnoresAnUndeployedCandidate is the proof
that the scope really is what it says: the release is etched live on every fork,
the candidate is deliberately absent at a different address, and the matrix
passes.

The check gets its subject the moment a release is frozen and declared, and from
then on it is red until that release is live everywhere — which is why the
deploy comes first.

What the head commit changed

57618df is a batch of review fixes, and it is mostly doc claims that were
false rather than code:

• the dirty-word decode above, plus MockDirtyWordOwner and its fuzz test
• low-level-calls narrowed from repo-wide to the one site
• the README claimed an unreachable RPC endpoint fails only the chain contract.
  26 fork tests in LibRainDeployTest say otherwise. The true claim is the
  narrower one: an outage cannot fail an assertion that needed no endpoint.
• the README claimed the chain group has no exemption. It is released-only.
• the README listed three verification groups. There are four; the
  record-anchored row was missing.
• the README justified the forge-std requirement by saying everything under
  src/ is test-and-script infrastructure. Four of fourteen files import
  forge-std; the requirement is transitive through the inherited abstracts.
• the README's Publish section named a v<x.y.z> tag and a workflow that does
  not exist, contradicting the sol-v* lifecycle documented above it.
• README and CLAUDE.md named rainix-sol-{test,static,legal} as commands.
  They are reusable workflow names and no longer exist in rainix; what each one
  runs is documented instead.

QA

• Discriminating tests: 130 across 13 suites. 128 pass; the 2 failures are the
  RPC 500 above.
• Mutations: 24 across two probes at earlier heads, with what has moved since
  named below rather than implied away.
• Oracle: issues Address registry: immutable root, mutable bytes32 bindings on Zoltu, plus a lib to read it and a post-deploy check #25 and Parameterized deploy-verification abstract: derive expectations from creation code, check against source and every chain #27, not the code. The pins have a second independent
  oracle in the Zoltu factory itself — deployed to and read back, rather than a
  recomputation of the formula the library uses.
• Category check: both issues describe categories rather than instances — an
  opaque bytes32 name rather than an owner, and a suites-by-networks matrix
  rather than a per-version or per-chain test.

Discriminating tests

The registry is never mocked: AddressRegistry is deployed through the Zoltu
factory, so every test runs at the pinned address with the pinned code hash.

• Mutability: testRegisterRebind, testRegisterRebindSameAccount,
  testRegisterRebindRepeatedly (only the most recent binding counts),
  testRegisterRebindEvent (a re-binding emits, so an indexer is not left
  serving the original), testRegisterRebindOnlyRoot (a bound name gives nobody
  else authority, and the failed attempt leaves the binding intact).
• What a binding may never be: testRegisterZeroAccount,
  testRegisterZeroAccountCannotUnbind.
• The reverting read is the only read: testGetUnsetReverts,
  testGetNoGeneratedMappingGetter, testGetNoOtherEntryPoint (fuzzed selector
  outside the two interface selectors).
• Post-deploy semantics: testCheckResolvedAddressesUnaffectedByRebinding
  is the load-bearing one — after deploying, root re-binds the name; the
  registry answers differently, the deployed contract does not, the check
  against the deployment's own value still passes, and a check against the new
  registry value fails. That is the whole argument for verifying after rather
  than before, as a test.
• Reads that cannot be answered are never passes:
  ...UnreadableTargetReverts (an address with no code static-calls
  successfully and returns nothing), ...RevertingReadReverts,
  ...DirtyWordReverts, ...ChecksEveryRead, ...LengthMismatchReverts,
  ...OnNetworksNoNetworksReverts,
  ...OnNetworksLengthMismatchRevertsBeforeForking (the network is a
  deliberately unconfigured RPC alias, so reaching a fork at all is the
  failure).
• The suite registry: testAllSuitesIsReleasedThenCandidate,
  testEverySuiteIsSelectableByKey, testSuitesSharingCreationCodeSelectApart,
  testUnknownSuiteNamesEveryValidSuite, testEmptySuiteIsUnknown,
  testSuiteNamesIsTheRegistry, testDuplicateSuiteKeyReverts.
• The broadcast: testRunUnknownSuiteRevertsBeforeReadingTheKey and
  testRunUnsetSuiteReverts pin the ordering,
  testDeployNetworksDefaultsToSupportedNetworks the default,
  testSelectedSuiteCarriesTheRecordedPins that what is broadcast is what is
  recorded.
• The internal group's blind spot, from both sides:
  testWrongContractSnapshotPassesInternalConsistency feeds a fully consistent
  snapshot of one contract in as the candidate of a repo whose source is
  another, asserts it really is a different contract, and asserts every internal
  check passes anyway. testWrongContractSnapshotCaughtBySource takes the same
  fixture and gets CandidateSourceMismatch.
• One broken field at a time: testStoredAddressMismatchReverts,
  testStoredCodeHashMismatchReverts,
  testStoredRuntimeCodeHashMismatchReverts. The last is the only thing between
  a corrupted RUNTIME_CODE and a green suite — the address and code hash still
  agree with the creation code in that case.
• The record group: testFrozenSnapshotDeclaredPasses (so the failures are
  discriminating), testFrozenSnapshotUndeclaredReverts,
  testFrozenSnapshotDeclaredByAnotherSuiteReverts (a repo that declares SOME
  releases and misses one is the case that actually happens, and is
  indistinguishable from a full declaration to anything that only counts),
  testFrozenSnapshotMatchesTheDeclarationNotTheText,
  testFrozenSnapshotIgnoresACommentedOutDeclaration,
  testFrozenSnapshotWithoutADeployedAddressReverts.
• The derivation reads only the creation code:
  testDerivationLeavesNoCodeBehind and
  testDerivationRestoresCodeAtDerivedAddress. The second checks the NONCE as
  well as the code, and the nonce is the discriminating part: a local deploy
  that survived leaves the same runtime code, so code alone cannot tell "put back"
  from "deployed over the top", but CREATE2 leaves nonce 1 where a restored
  etch is at nonce 0. A leaked local deploy at a persistent address would be
  compared against itself and every chain would pass regardless.
• Chain, negative: testChainNotDeployedReverts,
  testChainNotDeployedRevertsForALaterSuite (the second suite, so a matrix
  that stopped after the first would pass), testChainCodeHashMismatchReverts
  — which doubles as the proof that the expectation is DERIVED rather than
  observed, since the wrong code is etched at the very address the check reads —
  and testChainFailureNamesTheNetworkChecked.
• The matrix is a matrix: testChainMatrixCoversEverySupportedNetwork walks
  every network supportedNetworks() returns;
  testChainMatrixReachesTheLastSupportedNetwork starts on a fork the matrix
  does not end on and asserts the completed run leaves the LAST network
  selected, which a run that stopped early cannot do.
• The chain scope: testChainIgnoresAnUndeployedCandidate, in its own file
  because the suites a contract inherits are the whole of what the matrix runs
  over — a second scope is a second contract, not a second function.
• The library's own invariant: testZoltuDerivationMismatchReverts mocks
  the factory into answering with an address it did not deploy to, otherwise
  unreachable since the derivation etches the factory bytecode itself.
• The release guards, driven directly:
  testIsTagAcceptsWhatAFreezeCanWrite,
  testEveryFreezableVersionIsATagTheRecordFinds (fuzzed over X.Y.Z, so
  "freezable" and "found by the record walk" are the same set rather than two
  lists), testTagForVersionRefusesNonStrict,
  testFreezeRefusesAnEmptyRelease,
  testFreezeLeavesNothingBehindWhenThereIsNothingToFreeze,
  testFrozenSnapshotPathsFindsEveryReleaseAndNothingElse,
  testFrozenSnapshotPathsExcludesTheRollingSnapshot,
  testFrozenSnapshotPathsOnAMissingRoot.
• The generated declaration: testReleasedImportBlockAliasesEveryRecord,
  testReleasedLibraryBlockDeclaresEveryRecord,
  testReleasedLibraryBlockKeysAreUniquePerRelease,
  testReleasedLibraryBlockCarriesTheTemplateDependencies,
  testWriteReleasedSuitesLibReadsTheRecordItIsHanded,
  testSortedRecordPathsOrdersTagsAsVersions,
  testRecordPathsForContractSelectsOneContractInTagOrder.

Fork tests use Arbitrum and Base rather than all five where the loop itself is
what is under test; an earlier five-network version failed on CI's
base_sepolia endpoint answering 408 Request timeout on the free plan.

Mutations applied, and where the evidence stops

Probe A — 12 over the verification abstracts, at 10b14d5. 12/12 killed.
The load-bearing row is dropping the source anchor: it kills only
testWrongContractSnapshotCaughtBySource, and every internal-group test,
including the one that feeds it a wrong-contract snapshot, still passes. That is
the measured version of "the internal group cannot catch this" rather than an
assertion about it. One mutation SURVIVED on the first pass — not reverting the
derivation's state snapshot — because
testDerivationRestoresCodeAtDerivedAddress
compared only code, and a surviving local deploy leaves the same code. The nonce
assertion was added for that and the mutation dies now: a gap found and closed,
not a green reported.

Probe B — 12 over the suite registry, the broadcast and the release library,
at a later head. 11 killed, 1 recorded gap. Killers were
testDuplicateSuiteKeyReverts, testAllSuitesIsReleasedThenCandidate,
testSuiteNamesIsTheRegistry, testUnknownSuiteNamesEveryValidSuite,
testEverySuiteIsSelectableByKey, testEmptySuiteIsUnknown,
testRunUnknownSuiteRevertsBeforeReadingTheKey, testRunUnsetSuiteReverts,
testDeployNetworksDefaultsToSupportedNetworks,
testTagForVersionRefusesNonStrict and testTagForVersionConvertsDots.

Both probes key results by Contract::test rather than by bare test name,
require every killer to FLIP from pass to fail rather than merely be failing,
and refuse to score a mutation whose named tests produced no result line. Two
harness bugs were caught by exactly those guards before any result was believed:
an anchored --match-test regex that matched nothing (forge matches signatures,
not names), and forge's trailing "Failing tests:" summary being re-parsed under
the wrong suite, which rewrote a real PASS into a FAIL.

The recorded gap. A failed vm.revertToState is guarded with
DerivationSnapshotRevertFailed and no test can fire it: forge does not return
false for a snapshot taken moments earlier in the same call, and the existing
tests catch a revert that is DELETED rather than one that runs and returns
false. It stays, because the alternative — the (reverted); that was there —
silently leaks a planted etch and nonce reset into every later derivation in the
loop, and every result after that describes state the previous iteration
created.

What the probes no longer cover, stated rather than implied. Probe A ran
before the rename (RainDeployVerifyOffline → RainDeployVerifySnapshot,
DeployVersion → DeploySuite, testDeployPins* → testSnapshot* /
testChain*) and before the chain group was scoped to released suites; the
assertions it scored are unchanged in substance but the scores were not re-run
against the current names. One of probe B's rows is gone entirely along with the
mechanism it mutated — staging through an existing directory, which no longer
exists now that writeSnapshot has one output root. And everything added from
0c5967d onward — the record-anchored group, the record-and-declaration
one-call generator, LibAddressRegistryReleased, the candidate chain scope, and
the head commit's decode fix — has discriminating tests and no mutation pass.
Recording that rather than implying coverage I did not measure.

Oracle

The issues are the oracle, not the code. #27 is the oracle for what each group
must catch, and the groups are sorted by anchor precisely so no group's coverage
is claimed for another. For the derivation itself there is a second, independent
oracle: the pure zoltuAddress formula and an actual deploy through the etched
Zoltu factory bytecode are cross-checked against each other, so neither is
checked only against itself.

Category check

#25's example is initial ownership; it says the problem is not owner-specific
and nothing here is — the key is an opaque bytes32, the value is an address,
and neither lib has a notion of an owner, a role or an initializer. The
post-deploy check is source-agnostic for the same reason: it covers "the
deployment holds what it should" as a category rather than "the registry said
the right thing" as one instance.

#27's example is rain.factory.deploy — three versions, five networks, five of
fifteen facts checked. Nothing here is specific to that repo, to a version count
or to a network: the parameter is a creation code, the suite set is an array,
and the network set is supportedNetworks(). Adding a suite is an array entry
and adding a network is a supportedNetworks() entry; neither adds a test,
which is the category rather than the instance. Every error any of these
contracts can revert with has a test.

n/a

• Screenshot — n/a, no GUI.
• A live deployment — n/a, nothing has been broadcast; the deploy follows
  the merge.

Things for you, not for me

1. Three natspec/README claims are stale in the same direction, and I did not
   fix them here. test/src/concrete/AddressRegistryDeployChain.t.sol's
   natspec says the contract fails and calls the root a "placeholder";
   script/Deploy.sol's says the chain test "fails until every supported
   network has the registry, which is the state this repo is in right now"; and
   the README's step 2 says "It is red today because step 1 has never been run."
   All three predate scoping the chain group to released suites, and all three
   are now false — the contract passes with nothing to check, and the root is
   address(0) by design rather than as a stand-in. Flagging rather than
   folding in, because it is a source edit outside this description.
2. rain.deploy is now a mixed shape. The deploy-repo convention is
   "audited code only, internally consistent, version↔snapshot↔pins enforced by
   a test". AddressRegistry fits it. The tooling libs do not and were never
   meant to: isStartBlock, findDeployBlock, deployToNetworks,
   deployAndBroadcast and checkResolved* are forge script/test-time
   helpers that take a Vm, are never deployed, are never audited as deployed
   code and have no pins. So a sol-v* tag now simultaneously means "these pins
   are live" and "here is a tooling release", and those two have no reason to
   move together. Coherent — the tooling has no on-chain surface to be
   inconsistent with — but not what the convention anticipated. Reporting, not
   resolving.
3. The first tag is what writes src/generated/<tag>/. cutRelease() is
   wired and the record machinery is tested, but no release has been cut, so
   releasedSuites() is empty and the chain group has no subject. The order
   from here is: merge, dispatch the deploy, confirm the chain group, then tag.
4. There is no test for script/Deploy.sol or script/Build.sol. Neither
   this repo nor rain.factory.deploy tests a deploy script, and the stated
   tree convention (test/src/** mirrors src/**) has no slot for one. What
   the empty bodies leave untested is thin — ExampleDeploy and
   ExampleDeploySuites drive the same inherited machinery from test/ — but
   the residual risk is a suite: string disagreeing between the workflow and
   the declaration. It is mitigated by the revert naming every valid key and by
   failing in the first seconds of a dispatch rather than after any broadcast.
   Flagging rather than inventing a location for a script test unasked.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔴 Critical · up to dd2d9

The change adds mutable address bindings and post-deployment verification, but the current revision is not merge-ready because the deployed registry has no usable operator root, the default network verification fails, and the release process exposes credentials to mutable external workflow code; several bounded validation and test-isolation issues also remain.

🚥 Pre-merge checks | ✅ 4 | ❌ 1

❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Linked Issues check	❓ Inconclusive	The implementation covers issues #25 and #27, but the excluded generated candidate snapshot cannot be verified because path filtering omitted it.	Review src/generated/candidate/AddressRegistry.sol, excluded by !/generated/, before merging.

Naming: this should be script/Build.sol, not script/BuildPointers.sol.

Eight repos already call theirs Build.sol — rain.flare, rain.dia, rain.erc4626.words, raindex, rainlang, rain.merkle, rain.pyth, rain.sol.codegen. Four call it BuildPointers.sol — rain.factory.deploy, rain.verify, rain.math.float, S01-Issuer/st0x.deploy. The split tracks the deploy side rather than a different job, so it is a dialect for the same thing, and this PR would make it five against eight.

The wider ruling is rainlanguage/rainix#304: pointer generation is part of build, not a separate script you remember to run. Under CREATE2 the deployed address and codehash are pure functions of the bytecode — as derived as the ABI — and in the Build.sol repos the build already regenerates several derived artifacts together. Every guard around this exists only because regeneration is separable: the copy-artifacts gate, the git-clean gate, and cut-release's regenerate-then-freeze ordering, whose inversion silently publishes one address while permanently recording another.

Renaming here is the cheap half and worth doing before this lands. Folding generation into the build is #304 and need not block this PR.

Also relevant to this PR's "post-deploy cross-network verification": #27 proposes a parameterized abstract in this repo, so the cross-chain matrix is derived from creation code and generated per version rather than hand-enumerated per version and per chain. test/src/concrete/AddressRegistryDeployPins.t.sol is the first thing that would inherit it. Not asking to change that here — flagging the overlap so the two do not diverge.

Reviewed 57618df: approve — read the full diff, ran the suite (130 tests, 128 pass), slither (0 results) and reuse lint (53/53) locally; the only red is an Arbitrum RPC 500 on fork creation, not an assertion.

Verified rather than assumed:

• AddressRegistryDeployChainTest passes at 547 gas because releasedSuites() is empty, so it forks nothing. That is the released-only scope working as designed, and the tag release is what gives it a subject.
• checkResolvedAddresses reports a dirty-word read as ResolvedAddressReadFailed; the new test was watched failing against the unfixed decode before being kept.
• low-level-calls is suppressed at the single staticcall rather than repo-wide; deleting the inline disable reproduces exactly one finding at that line.
• [package].version = 0.1.5 matches the last published Soldeer revision.
• cutRelease() orders freeze before the released-lib regeneration, and rainix-tag-release sets the version before running it.

Known and accepted: the NatSpec on AddressRegistryDeployChainTest and script/Deploy.sol still describe that test as failing until deployed. It reads releasedSuites(), so that stays inaccurate after the deploy too — flagged, deliberately not fixed here.
