refactor(deploy): migrate deploy constants to the per-version snapshot canon - #253
refactor(deploy): migrate deploy constants to the per-version snapshot canon#253thedavidmeister wants to merge 10 commits into
Conversation
…t canon Bring rain.math.float onto the same deploy-constants model as raindex / rain.factory / st0x.deploy: each release's deployment record lives in a frozen snapshot under src/generated/<tag>/, generated rather than hand-pinned. Both deployables are placed by Zoltu's deterministic proxy, so every address is a pure function of its creation code — the whole record is reproducible offline. BuildPointers now etches a Zoltu factory, deploys the log-tables data contract then DecimalFloat (that order: DecimalFloat's constructor reads the log-tables codehash), and emits src/generated/DecimalFloatDeploy.pointers.sol. deployTag()/freezeSnapshot() freeze it to src/generated/<tag>/ keyed off foundry.toml [package].version, with the immutability guard that reverts rather than rewrite a frozen snapshot without a version bump. The generated record reproduces the previously hand-pinned constants byte for byte, which also pins 0.1.7 — published to soldeer 2026-07-14 with no pinned constants, so the old check was failing with MISSING: *_0_1_7. LibDecimalFloatDeploy now aliases the generated record. The four public constant names consumers import are unchanged, so this is not a consumer break; the *_0_1_1 literals are retired into src/generated/0_1_1/. The tagged-constants test drops its FFI/registry dependency — and with it the vm.skip that rainix's no-ignored-tests gate bans (and that reds main today). It now re-derives the record offline and asserts no drift, checks every frozen snapshot carries its full suite (the named imports enforce completeness at compile time), and asserts the current release's snapshot matches the live constants. No network, no skips: it always runs and passes or fails. script/check-published-deploy-constants.sh is deleted. Verifying that every PUBLISHED version has a snapshot is inherently a query against remote state, so it belongs in shared CI where an unreachable registry is a loud, retryable failure rather than a silent skip — rainlanguage/rainix#271.

Bump rain-sol-codegen 0.1.0 -> 0.1.1 and freeze via LibSnapshot.freezeSnapshot rather than a deployTag()/freezeSnapshot() pair defined in this repo. The canon was already copy-pasted across raindex, st0x.deploy and rain.factory and had diverged — deployTag() byte-identical in all three, the freezing half in three shapes, and the immutability guard in only half of them. Landing another copy here would have made it four. LibSnapshot (rain.sol.codegen#26, published in 0.1.1) is the shared implementation, and it ships the guard with the mechanism so a repo cannot adopt snapshots and omit the safety property. Regenerating through the shared library is a no-op: src/generated/ is byte identical, so this is a pure refactor of how the record is produced, not what it contains. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…runtime bytecode The first cut of this migration emitted BYTECODE_HASH = 0 and pinned only address + codehash. Both were wrong. BYTECODE_HASH was zero because two deployables shared one pointers file, so there was no single instance to hash and address(0) got passed to LibFs.buildFileForContract. A constant named BYTECODE_HASH sitting at zero in a deploy record is worse than absent: importing it silently compares against nothing. Each deployable now gets its own file with its own instance, so the hash is real. Pinning only address + codehash left every past release unreproducible and unverifiable once the current build diverges — the exact incompleteness the audit skill rates HIGH. Each record now carries the creation bytecode it is deployed FROM and the runtime bytecode it is verified AGAINST, so a release stays reproducible from the repo alone. The 0.1.1 historical is BUILT from tag v0.1.1 rather than copied from literals: its deps are all published versions, so the tag rebuilds, and it re-derives 0xc51a1425/0x2573004a and 0xBee0eEFa/0x7a93d031 — independently confirming the constants 0.1.1 has carried all along. Because each snapshot now holds its own bytecode, every release self-verifies offline and forever: per record keccak256(RUNTIME_CODE) == BYTECODE_HASH, and deployZoltu(CREATION_CODE) lands on DEPLOYED_ADDRESS with that runtime on-chain. testReleasesAreDistinctHistoricals guards the failure mode where a "frozen" tag silently re-derives from current source — 0.1.1 and 0.1.7 shipped different bytecode, so their records must not converge. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…l copy Bump rain-sol-codegen 0.1.1 -> 0.1.2 and emit DEPLOYED_ADDRESS through the shared helper. LibCodeGen already owned this family — bytesConstantString, uint8ConstantString, bytecodeHashConstantString — and address was the missing member, so raindex, rain.factory and st0x.deploy each hand-rolled it (rain.sol.codegen#28 added it upstream). BuildPointers now carries no hand-rolled helpers at all: LibCodeGen for the constant emitters, LibFs for file placement, LibSnapshot for the tag, freeze and guard. Regenerating through the shared helper is byte-identical, so this is a pure refactor. That is not a given: the shared version applies the MAX_LINE_LENGTH wrapping the local copy lacked, so identical output confirms the copies had not silently diverged in behaviour as well as location. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Bump rain-sol-codegen 0.1.2 -> 0.1.4 and regenerate. The generated file is a deploy record (address, codehash, creation and runtime bytecode), not a function pointer table, and src/generated/ already says it is generated: src/generated/<Contract>.pointers.sol -> src/generated/<Contract>.sol src/generated/<tag>/<Contract>.pointers.sol -> src/generated/<tag>/<Contract>.sol script/BuildPointers.sol -> script/Build.sol, which rainix#272 now requires: it matches the codegen script by exact name and errors rather than silently skipping regeneration. Every deploy constant reproduces byte for byte; the only content change is the generated header, which no longer names a build script. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
buildDeployPointersFor -> buildDeployRecordFor buildDeployPointers -> buildDeployRecords The docs already called these the deployment record; only the names still said pointers. Nothing here builds a function pointer table. Generated output is unchanged. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Rework note @865a49e42a4703562a1af899cc90794f6790d55c: rework the PR to fit the split release lifecycle — deploys never gate merges (the deploy-before-merge choreography is superseded); remove or restructure anything in the PR that waits on a deploy; where deploy constants/pins are involved, follow the *.deploy repo convention (audited code only; version ↔ snapshot ↔ pins internally consistent; tag-release lifecycle). Whatever states follow the rework (including a typed blocked-on the repo's migration if one is genuinely needed) are the producer's ordinary transitions. Executes the 2026-08-06 ruling: rainlanguage/issue-pr-cron#221 |
CLAUDE.md still carried the deploy-before-merge choreography — "trigger the Manual sol artifacts workflow on the PR's branch before merge ... do NOT wait for merge before deploying". No merge waits on a deploy: a source-changing PR regenerates its deployment record and lands on that record, and the on-chain deploy is a separate manual dispatch run when someone decides to publish. The prod fork tests are what made that read like a gate, so say what they actually assert: LibDecimalFloatDeployProd forks the five networks and checks the current record's addresses already carry the expected code, which is a statement about the state of the chains, not about the branch under test. The constants paragraph was also describing the pins this PR removed. Expected addresses and code hashes are generated now: frozen per release under src/generated/<tag>/, current build in src/generated/, aliased by LibDecimalFloatDeploy, and re-derived offline from their own bytecode by LibDecimalFloatDeployTaggedConstantsTest. It named testDeployAddress and testExpectedCodeHashDecimalFloat, neither of which exists any more. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
rainix's agent-context-cap gate fails both static checks: CLAUDE.md is the whole of this repo's per-session agent context and it was 6593 bytes on main against a 4096 cap, which the previous commit pushed to 7283. The gate is a floor-only ratchet, so the answer is to cut, and its own rule says which lines go: anything a capable agent would merely take a moment to FIND rather than get WRONG. Cut on that rule: the build-command list (foundry.toml, package.json, flake.nix say it), the directory-by-directory architecture tour (src/ says it), the dependency list (foundry.toml says it), the compiler settings (foundry.toml says it), the license section (REUSE.toml says it). Kept, because each is a mistake waiting to happen: no NaN/Infinity/negative zero, so IEEE intuitions are wrong here; the Rust crate executes the Solidity in revm rather than reimplementing it, and its bindings need a forge build; the deploy/record lifecycle above; the three packing modes, whose contracts differ in ways nothing at a call site advertises; exponent overflow reverting while coefficient truncation does not; SPDX headers. Now 2938 bytes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

GitHub Actions workflow_dispatch run workflow on selected branch actions/checkout default ref github.ref
💡 Result:
When you trigger a workflow manually using the workflow_dispatch event, GitHub Actions sets the github.ref context to the reference (branch or tag) you selected when initiating the run [1][2]. By default, the actions/checkout action automatically uses this github.ref value [3][4][5]. If you do not explicitly define a ref parameter in your checkout step, the action will check out the branch or tag that triggered the workflow [3][4]. For example: - uses: actions/checkout@v4 In this configuration, if you trigger the workflow on a branch named feature-xyz, actions/checkout will automatically check out feature-xyz [2][3]. If you wish to override this behavior and force the checkout of a specific branch (e.g., main or master) regardless of the branch selected during the manual trigger, you must explicitly set the ref parameter in your workflow file [2]: - uses: actions/checkout@v4 with: ref: main This ensures that the specified branch is checked out, ignoring the reference that triggered the event [2]. The internal logic of actions/checkout handles this by checking the input ref; if it is provided, it uses that value, and if it is omitted, it defaults to the event's reference (or the repository's default branch if no trigger context is available) [4][5].

Closes#252.
The deploy constants were hand-maintained pins in
LibDecimalFloatDeploy.sol. This migrates them to the per-version snapshot canon: generated from source, frozen per release tag, and reproducible offline.The record
Each deployable gets its own generated file, one contract per file, carrying the complete record:
DEPLOYED_ADDRESSBYTECODE_HASHCREATION_CODERUNTIME_CODEA pin carrying only address + codehash cannot reproduce or independently verify a past release, which is why the record includes both bytecodes. One file per contract because
BYTECODE_HASHidentifies a single instance — combining two deployables into one file leaves it meaningless.Every address is computed offline through a locally etched Zoltu factory, so no network access is needed to build or verify the record.

<Contract>.sol, not<Contract>.pointers.sol. The file is a deploy record; only the interpreter/word repos generate an actual function pointer table, so "pointers" named the exception rather than the thing, andsrc/generated/already carries the "generated" part.script/BuildPointers.sol->script/Build.sol, which rainlanguage/rainix#272 now requires: it matches the codegen script by exact name and errors rather than silently skipping regeneration, as the oldhashFilesguard did.Pins rain-sol-codegen 0.1.4.
Verification
0_1_1's header transform is proven, not asserted. The build script freezes only the current tag, so0_1_1is not regenerated by it.0_1_7has both a 0.1.2-generated file and a true 0.1.4 regeneration, so the transform was validated against that pair — byte-identical on both files — before being applied to0_1_1.script/Build.solreproduces the committed tree exactly, socopy-artifactsdiffs clean — and on rainix#272 that step actually runs rather than skipping.vm.skipmain-red that the hand-pins required.Known reds (pre-existing, not from this PR)
testRoundTripFuzzPow— fails on main independently of this branch (pow: negative-exponent squaring loop reverts Panic(0x11) instead of ExponentOverflow #239).testProdDeployment*x5 — the deploy gap: the record pins addresses that are not deployed on these networks yet.Neither is caused or fixable by this diff.
