rainix-tag-release invokes rain.deploy's cutRelease() instead of reimplementing the freeze

[thedavidmeister]

Closes #301
Unblocks rainlanguage/rain.deploy#141

rainix-tag-release required snapshot-generate-cmd as free-text shell, so every deploy repo hand-rolled the release freeze and the first consumer to write it inverted the ordering.

The standard for that already exists, in Solidity, in rain.deploy — BuildScript.cutRelease() and LibRainDeploySnapshot.freeze, written deliberately as the one implementation for deploy repos to converge on (rainlanguage/rain.deploy#132, #138). So this PR makes rainix invoke it rather than reimplement it.

What changed

snapshot-generate-cmd keeps its name and becomes optional, defaulting to:

forge script ./script/Build.sol --sig "cutRelease()" && forge fmt

A deploy repo whose script/Build.sol extends BuildScript passes nothing. rain.deploy's package-release.yaml works unchanged.

The command runs under set -euo pipefail via env: rather than string interpolation, so a; b cannot hide a's failure behind b's success and the input is not a template-injection surface.

What was removed

This PR previously reimplemented the freeze in Rust. That is deleted:

• rainix-static/src/cut_release.rs
• its registration in rainix-static/src/main.rs
• the soldeer_gate pub(crate) widening it needed
• .github/actions/cut-release/

rainix-static/ is now byte-identical to main. The PR is one file.

Why the Rust could not stay

The two designs were mutually exclusive, not merely duplicated. cut_release.rs refused a generate command that creates the tag directory; cutRelease() creates it. No consumer could satisfy both.

cutRelease() also runs regenerateLibs() after the freeze, so the released-suites declaration names the release being cut. A CI-side copy cannot do that — it would have to re-enter the repo's Solidity to know what to regenerate.

And the Rust default named script/BuildPointers.sol while copy-artifacts in this same repo matches script/Build.sol exactly and hard-errors otherwise. One repo, two contradictory expectations.

The guards

Every guard the Rust implementation carried has a Solidity counterpart already on rain.deploy main:

guard	where it lives now
version read	LibRainDeploySnapshot.deployTag
tag shape	tagForVersion / isStrictTriple
freeze ordering	freeze takes the regeneration and runs it first, in one call
already-frozen refusal	SnapshotAlreadyFrozen
nothing-to-freeze refusal	NothingToFreeze
monotonic release	NonMonotonicRelease
append-only record	frozen-snapshots-append-only, already in shared CI

Only bash -euo pipefail stayed on the rainix side.

QA

• Discriminating tests: n/a — rainix has no harness that executes a reusable workflow's command line (test/bats covers devshells and composite actions only). The discriminating evidence is rain.deploy's package-release.yaml, which passes snapshot-generate-cmd with a cutRelease() value: it is rejected by the pre-change contract in this PR and accepted after, which is rain.deploy#141.
• Mutations applied: n/a for the diff — a workflow input default and an env:-quoted run:. The negative control is the deleted code itself: cut_release.rs erroring on "the generate command created the tag dir itself" is the pre-change behaviour, and it kills every real consumer.
• Oracle: rain.deploy main — BuildScript.sol, LibRainDeploySnapshot.freeze, and the package-release.yaml that must keep working. Not derived from this repo.
• Category check: rainix-tag-release delegates cut-release to consumers; the freeze ordering is a silent-corruption hazard #301 asks that the freeze stop being hand-rolled per repo. Covered: it is now one implementation, in rain.deploy, invoked by default. It asked for that implementation to live in rainix-static; the org has since made rain.deploy the home of the standard, so it lives there instead.

Not fixed here

• README.md:150 still names BuildPointers.sol.
• The sed-first-version=-line bump vs [external.package].version seam.

📝 Walkthrough

Walkthrough

The PR adds rainix-static cut-release, which regenerates and formats candidate snapshots, validates release inputs, freezes verified contents into versioned directories, and integrates this process into the tag-release workflow through a composite GitHub Action.

Changes

Release snapshot freezing

Layer / File(s)	Summary
Release freeze implementation rainix-static/src/cut_release.rs, rainix-static/src/soldeer_gate.rs	Adds validation, regeneration, formatting, recursive copying, byte-identity checks, append-only writes, and comprehensive failure-case tests.
rainix-static command integration rainix-static/src/main.rs	Registers and documents cut-release, applies default arguments, dispatches the command, and reports errors or the frozen tag.
Release workflow integration .github/actions/cut-release/action.yml, .github/workflows/rainix-tag-release.yaml	Adds the shared composite action and changes the tag-release workflow to pass an optional pointer-generation command.

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

Merge Risk: 🟡 Moderate · up to d3258

The release workflow now regenerates and formats the candidate before freezing it, but a failed write can leave a partial snapshot that blocks retry, and the default generator command may not work for every supported repository. These bounded release-readiness risks should be resolved or explicitly accepted before merging.

@thedavidmeister Reviewed the current branch.

I found no review findings.

The release workflow removes snapshot-generate-cmd and passes only pointers-generate-cmd to the new composite action. The composite action runs the new rainix-static cut-release command from its own checkout through the path: flake reference.

cut_release.rs enforces the required sequence:

1. Validate the release plan before generation.
2. Run the generate command.
3. Run forge fmt.
4. Refuse a generator-created numbered snapshot.
5. Copy the non-empty candidate tree into the new numbered directory.
6. Re-read both trees and verify byte equality.

The command also reuses soldeer_gate::read_local_version and frozen_snapshots::is_tag, so the release-version parsing and append-only tag acceptance stay aligned.

HELD — do not merge. The design this PR sits in is unresolved, and merging now ships something we would immediately undo.

Specifically: this PR deletes snapshot-generate-cmd and adds pointers-generate-cmd, defaulting to forge script ./script/BuildPointers.sol. Two open questions decide whether that input should exist at all.

• BuildPointers should not exist: pointer generation is part of build #304 — pointer generation is part of build, not a separate script. Eight repos already call theirs Build.sol; four call it BuildPointers.sol, and the split tracks the deploy side rather than a different job. If that holds, cut-release runs the repo's build and rainix asks for nothing — so this PR would be removing one knob and adding another in the same change, while enshrining the minority spelling as the default.
• Release-time verify runs the whole suite and asserts nothing about the snapshot it publishes #303 — release-time verify runs the whole suite and asserts nothing about the snapshot it publishes. The frozen dir this workflow creates is imported by no test at the moment it is created, while the tagged-constants tests re-verify directories an append-only gate already makes immutable. That reshapes what cut-release should hand to the verify step.

What stands regardless of both: the Rust cut-release, the guards reusing frozen_snapshots::is_tag and soldeer_gate::read_local_version, and the regenerate-then-freeze ordering being unrepresentable rather than documented. The ordering hazard is real and live — S01-Issuer/st0x.deploy's script/cut-release.sh copies candidate at line 47 and only then runs forge script at line 51.

The two caller PRs are held with it, since they were sequenced behind this one: rainlanguage/rain.factory.deploy#9 and S01-Issuer/st0x.deploy#305. Neither is a no-op — snapshot-generate-cmd is required: true on main today, so dropping it before this lands fails at workflow_call startup.

[thedavidmeister]

Caller count correction: there are three, not two.

The sweep behind this PR found two callers passing snapshot-generate-cmd — rain.factory.deploy and st0x.deploy. A third has appeared since: rainlanguage/rain.deploy#26 switches that repo from rainix-autopublish to rainix-tag-release and declares snapshot-generate-cmd: forge script ./script/Build.sol && forge fmt. It was not counted because it had not landed when the sweep ran.

That PR is correct as it stands — the input is required: true on main today, so it must pass one. But it means the deletion here has three callers to sequence, not two, and the caller PRs currently open (rainlanguage/rain.factory.deploy#9, S01-Issuer/st0x.deploy#305) do not cover it.

Note also that #26 uses script/Build.sol, not BuildPointers.sol — so the default this PR would have introduced (forge script ./script/BuildPointers.sol) is already the minority spelling among live callers, which is the substance of #304.

This PR remains HELD pending #304 and #303.

Ruled by the human, verbatim:

302 needs to match the latest rain.deploy conventions and process

everything in rainix is moving TO THE NEW STANDARD, don't care if it breaks old things

there should not be any rust or anything else, it should be the solidity thing we built only

rain.deploy is the reference implementation; rainix conforms to it. Pushed 5db1688 to this branch — additional commits, no force-push, origin/main merged in first.

What this PR is now

The whole diff against main is one workflow file, .github/workflows/rainix-tag-release.yaml.

• snapshot-generate-cmd keeps its name, becomes required: false, and defaults to forge script ./script/Build.sol --sig "cutRelease()" && forge fmt.
• The step runs that command and nothing else — no wrapper, no post-check.
• The value travels via env: instead of being interpolated into the run: body, and runs under set -euo pipefail.

Deleted: rainix-static/src/cut_release.rs, its main.rs registration and usage text, the pub(crate) widening of soldeer_gate::read_local_version, and the .github/actions/cut-release composite. rainix-static/ is now byte-identical to main.

actionlint is clean on the workflow.

Why the Rust went

rainlanguage/rain.deploy#138 landed src/abstract/BuildScript.sol. Its cutRelease() calls LibRainDeploySnapshot.freeze(vm, recordRoot(), regenerateSnapshots, snapshotContractNames()), which takes the regeneration as an argument and runs it FIRST, inside the same call — so "freeze, then regenerate" has no entry point to be written through. That is the invariant this PR's cut() was built to hold, already held in the repo that owns the record.

The two could not coexist. This PR's contract was that the supplied command generates ONLY and must not create the tag directory (cut_release.rs: "the pointer-generation command created {} itself — it must only regenerate"). rain.deploy's command IS the freeze, so every release would have hit that refusal.

cutRelease() also does work AFTER the freeze that no CI-side tree copy can do: regenerateLibs() re-emits the released-suites libs from the record that now holds the release being cut. Owning the freeze in Rust means owning half a release.

rainlanguage/rain.deploy#141 is answered by this rather than by a change there: package-release.yaml on main passes snapshot-generate-cmd: forge script ./script/Build.sol --sig "cutRelease()" && forge fmt, which is the input name that still exists, and is now also the default.

Fate of each guard this PR existed for

guard in cut_release.rs	where it is now
version read from foundry.toml	LibRainDeploySnapshot.deployTag, via .external.package.version
strict X.Y.Z, else refuse	tagForVersion reverts UnreleasableVersion. This workflow's "Resolve release version from the tag" step also already required ^[0-9]+\.[0-9]+\.[0-9]+$ on main
candidate/ must exist, and be non-empty	freeze reverts NothingToFreeze per named contract
refuse to overwrite src/generated/<tag>/	freeze reverts SnapshotAlreadyFrozen. frozen-snapshots-append-only still runs after the commit
regenerate → freeze ordering	structural in freeze: the regeneration is a parameter, run before anything is read or written
forge fmt before the copy	went, and is not needed: freeze copies inside the call, and forge fmt afterwards formats the record and the candidate identically
<tag>/ byte-identical to candidate/	true by construction — freeze writes the bytes it just read out of candidate. rain.deploy's testFreezeCopiesTheRegeneratedRollingSnapshot asserts it
the command must NOT create the tag dir	void — under the standard the command is what creates it
bash -euo pipefail around the consumer command	kept, in the run: step

No guard is left without a counterpart, so nothing was reimplemented on the rainix side. rain.deploy additionally holds two guards this PR never had: EmptyRelease (a release naming no contracts) and NonMonotonicRelease (a tag that does not strictly follow every tag already frozen).

Found while here, not fixed

• "Set foundry.toml version to the release version" rewrites the FIRST version = line with sed, while deployTag reads .external.package.version by TOML path. They agree on rain.deploy's foundry.toml because that line is first. Pre-existing on main, untouched here.
• README.md line 150 still documents rainix-copy-artifacts as running ./script/BuildPointers.sol, while the workflow itself requires script/Build.sol exactly and errors if src/generated/ is committed without it. Also pre-existing on main.
• The PR title and body above still describe the deleted design.

[github-actions]

@coderabbitai assess this PR size classification for the totality of the PR with the following criterias and report it in your comment:

S/M/L PR Classification Guidelines:

This guide helps classify merged pull requests by effort and complexity rather than just line count. The goal is to assess the difficulty and scope of changes after they have been completed.

Small (S)

Characteristics:

• Simple bug fixes, typos, or minor refactoring
• Single-purpose changes affecting 1-2 files
• Documentation updates
• Configuration tweaks
• Changes that require minimal context to review

Review Effort: Would have taken 5-10 minutes

Examples:

• Fix typo in variable name
• Update README with new instructions
• Adjust configuration values
• Simple one-line bug fixes
• Import statement cleanup

Medium (M)

Characteristics:

• Feature additions or enhancements
• Refactoring that touches multiple files but maintains existing behavior
• Breaking changes with backward compatibility
• Changes requiring some domain knowledge to review

Review Effort: Would have taken 15-30 minutes

Examples:

• Add new feature or component
• Refactor common utility functions
• Update dependencies with minor breaking changes
• Add new component with tests
• Performance optimizations
• More complex bug fixes

Large (L)

Characteristics:

• Major feature implementations
• Breaking changes or API redesigns
• Complex refactoring across multiple modules
• New architectural patterns or significant design changes
• Changes requiring deep context and multiple review rounds

Review Effort: Would have taken 45+ minutes

Examples:

• Complete new feature with frontend/backend changes
• Protocol upgrades or breaking changes
• Major architectural refactoring
• Framework or technology upgrades

Additional Factors to Consider

When deciding between sizes, also consider:

• Test coverage impact: More comprehensive test changes lean toward larger classification
• Risk level: Changes to critical systems bump up a size category
• Team familiarity: Novel patterns or technologies increase complexity

Notes:

• the assessment must be for the totality of the PR, that means comparing the base branch to the last commit of the PR
• the assessment output must be exactly one of: S, M or L (single-line comment) in format of: SIZE={S/M/L}
• do not include any additional text, only the size classification
• your assessment comment must not include tips or additional sections
• do NOT tag me or anyone else on your comment
