Slim rain.factory to the interface library (#46) - #47
Merged
Conversation
Move the deploy half — concrete CloneFactory, LibCloneFactoryDeploy pins, src/generated snapshots, deploy scripts, and their tests — to the new rain.factory.deploy repo. What remains is the ICloneable* interface surface, which imports nothing, so the deploy-only deps (openzeppelin, rain-extrospection, rain-deploy, rain-sol-codegen), the fs_permissions/rpc/etherscan config, and the manual-sol-artifacts deploy workflow all go too. Stays on autopublish. DO NOT MERGE until rain.factory.deploy has published its first release and the deploy-pin consumers (st0x.deploy) have repointed — else bumping to this version drops the pins consumers still import from here.

…pr_context fits itself to it (#81) #79 made an over-budget tool result a typed error so the caller could not improvise around it. For `pr_context` that guard never spoke. Its budget was `max_diff_bytes + MCP_MAX_RESULT_BYTES` — up to 332,000 bytes against a harness that stops at ~50,000 — so what reached the model was the HARNESS's replacement, untyped and with `is_error` UNSET, which is precisely the silent degradation #79 existed to remove. Ordering is the mechanism, not a preference: if the harness speaks first, every rule downstream about "a tool error is an instruction, re-call narrower" stops applying at the moment it is needed. THE CEILING, MEASURED. Not derived by halving a refused payload — that is how 32,000 was set, and how this gap survived #79. Probed against Claude Code 2.1.220 by calling `pr_context` through the real harness at increasing `max_diff_bytes` and reading the `tool_result` the model actually received. There are TWO independent gates and BOTH arrive with `is_error` unset: - a BYTE gate -> `<persisted-output> Output too large (NN KB)` plus a 2 KB preview. Delivered at 50,011 bytes, replaced at 50,176. NOT governed by `MAX_MCP_OUTPUT_TOKENS` (forcing it to 200,000 still replaced a 50,486-byte result). This one is the more dangerous: the preview it substitutes looks like the head of a real answer. - a TOKEN gate -> `Error: result (N characters ...) exceeds maximum allowed tokens`, governed by that variable (forcing it to 100 replaced a 4.5 KB result). This is the gate the live traces hit, at 63,742 and 56,789 chars. Isolating the token gate at `MAX_MCP_OUTPUT_TOKENS=10000` puts its boundary between 27,152 and 30,163 bytes, so this JSON measures 2.7-3.0 chars/token; nothing on the box sets the variable and 56,789 chars tripped it live, which puts the default near 19-21k tokens. Both gates land around 50 kB here. THE FIX. - `MCP_MAX_RESULT_BYTES` is 36,000, ~28% under both gates. The margin is not timidity: the token gate scales with CONTENT, and a diff of generated hex — which this org has in every `src/generated/*.pointers.sol` — tokenises far worse than the prose-and-code JSON the gate was measured on. At 36,000 even a payload at 1.5 chars/token stays inside a 19k-token cap. - ONE budget for every tool. `pr_context`'s special case is gone, and `max_diff_bytes` can no longer be raised past the budget, so no argument buys a call more room than any other call gets. - That is also what makes NARROWING CONVERGE. While the budget scaled with `max_diff_bytes` and the diff was truncated to `max_diff_bytes`, lowering the argument lowered allowance and payload equally — "re-call NARROWER" was a loop with no exit. Against a fixed allowance a smaller argument is a strictly smaller result, pinned by a monotonicity test. - `pr_context` does not wait to be refused: `fit_pr_context` shrinks the diff until the document lands under the budget. It terminates — each round removes at least the overflow from the cap, and one raw byte of diff is at least one byte of document, so it overshoots rather than undershoots. The document reports `diffBytes`, the new `diffIncluded`, and `diffTruncated`, so the gap between what exists and what was handed over is visible rather than inferred. The one case no argument can fix — metadata alone over the budget — is a typed error that says exactly that. The budget/ceiling relationship is a COMPILE-TIME assertion beside the constants, so raising the budget past the measured gate fails the build rather than quietly reinstating the defect. Four of the ten mutations for this change are killed that way; the rest by named tests. Verified live, same PR (rainlanguage/rain.factory#47), same harness: BEFORE (main @7df5496), default argument: received: HARNESS byte-gate (untyped) is_error=None chars=2248 AFTER, default argument: received: DELIVERED in full is_error=None chars=36631 AFTER, max_diff_bytes=300000: received: OUR typed refusal is_error=True chars=46 "max_diff_bytes must be an integer in 1..=36000" ...and the model then re-called within range and got the full result. No part of the existing #81 work is weakened: the pull-ref checkout, the binary postcondition, the sweep changes and the prompt rules are untouched.

Addresses the unresolved CodeRabbit thread on foundry.toml:29 (Major). The finding held on inspection at 18ea08e: [dependencies] declares only forge-std while soldeer.lock still resolved five packages and slither.config.json still filtered a dependency dir that would no longer be installed. - soldeer.lock regenerated with 'forge soldeer update', not 'install' -- install resolves FROM the lock and would have kept all five. update re-resolves from foundry.toml. The lock now holds forge-std and nothing else; @OpenZeppelin-Contracts, rain-deploy, rain-extrospection and rain-sol-codegen are gone. (remappings.txt is regenerated too but is gitignored here.) - slither.config.json filter_paths drops dependencies/@openzeppelin-contracts-5.6.1, keeps forge-std-1.16.1. Same class of drift found elsewhere and fixed: - CLAUDE.md described the deploy half as if it were still here: src/concrete/ CloneFactory.sol, src/lib/LibCloneFactoryDeploy.sol, src/generated/<tag>/, script/Deploy.sol, a --match-path at a deleted test file, a 'concrete contracts pin =0.8.25' rule with no concrete contracts left, fork tests that no longer exist, and the same four removed deps listed by name. Rewritten to describe a library repo, with the dependency line stated as a rule -- a new entry here means concrete code has landed in a library repo -- rather than a list that goes stale again. Added the autopublish release model, which was undocumented. - REUSE.toml annotated .gas-snapshot, which this PR deletes. Verified in rainix 53e96a7d sol-shell: forge build clean (6 files), reuse lint 22/22 compliant, forge fmt --check clean.
Second of the two slimming gaps the vetter named on 58a938e (the first, soldeer.lock / slither.config.json / CLAUDE.md, is a05d52f). README's 'Concrete implementations' section still presented CloneFactory as a thing in this repo. Rewritten to point at rain.factory.deploy, with the depend-on-which-package rule stated explicitly, plus a one-line statement at the top that this is the library half of #46. Also corrected the 'current interfaces in this repository' list, which omitted ICloneableFactoryV3 entirely -- it has been the current factory interface since 2026-07-11 and this repo is now nothing but interfaces, so that list is the README's main job.

Reviewed 2bf2615: APPROVE — slims rain.factory to the interface library per #46 step 4. Removes the concrete CloneFactory, LibCloneFactoryDeploy, the three frozen src/generated/0_1_3|0_1_4|0_1_5 snapshots, script/Deploy.sol + BuildPointers.sol, manual-sol-artifacts.yaml, the six deploy/concrete test files, and the now-meaningless .gas-snapshot. soldeer.lock regenerated via Coverage continuity verified one-for-one: every deleted file already exists on rain.factory.deploy main — src/concrete/CloneFactory.sol, src/lib/LibCloneFactoryDeploy.sol, all three generated snapshots, both scripts, and all six tests including LibCloneFactoryDeployProd.t.sol. Nothing is orphaned. Downstream safety verified: merging autopublishes an interfaces-only rain-factory 0.1.6. Soldeer revisions are immutable and this org carries the version inside the import path, so the only external deploy-pin consumer (S01-Issuer/st0x.deploy, pinned "0.1.1" with rain-factory-0.1.1/ prefixes) and rain.factory.deploy itself (pinned "0.1.5") keep working indefinitely. Neither moves until a deliberate bump, which would be a compile error rather than a silent resolution to the wrong thing. Known consequence, accepted: this makes rain.factory#51 unmergeable as written (three modify/delete conflicts, since it edits CloneFactory.sol and LibCloneFactoryDeploy.sol and adds src/generated/0_1_6/ in the library repo). #51 requires re-scoping regardless — under the split, ICloneableFactoryV4 belongs here and the open-salt implementation, its snapshot and tests belong in rain.factory.deploy. All four checks green. Zero unresolved review threads, queried via GraphQL rather than read off the checks rollup. Rulings-conformance:

The library half of the deploy/library split (#46). Practise run for the pattern before st0x.deploy.
What moves out
The deploy half is now in the new rain.factory.deploy repo (created, builds clean, 15/15 offline tests): concrete
CloneFactory,LibCloneFactoryDeploypins,src/generated/<tag>/snapshots,Deploy.sol+BuildPointers.sol, and all their tests.What remains here
The
ICloneable*interface surface — the abstract API consumers import. It imports nothing, so this PR also drops the now-unused deploy-only deps (@openzeppelin-contracts,rain-extrospection,rain-deploy,rain-sol-codegen), thefs_permissions/rpc_endpoints/etherscanconfig, and themanual-sol-artifactsdeploy workflow.rain.factorystays onrainix-autopublish— it's now a pure library repo, exactly one side of the split.Verified:
forge buildclean on the interfaces-only tree; rainixpre-commitclean.Merging republishes
rain-factory(0.1.6) as interfaces-only. Consumers that import the deploy pins (LibCloneFactoryDeploy.CLONE_FACTORY_DEPLOYED_CODEHASH) —S01-Issuer/st0x.deployat least — must first repoint torain-factory-deploy. So this merges only after:rainix-tag-release) lands + the Ankr fork-RPC key is restored (rain.factory.deploy's verify gate).rain.factory.deploycuts its first release (sol-v0.1.x), publishing the deploy pins.rain-factory-deploy.Interface-only consumers are unaffected throughout — that's why the library keeps the name. Sequencing tracked in #46.

Sequencing — updated 2026-08-13
The "do not merge yet" ordering above was written on 2026-07-24 on the assumption that publishing
rain-factory0.1.6 as interfaces-only would break deploy-pin consumers. It does not, and this can land first. Soldeer revisions are immutable and this org pins versions inside the import path, so:rain-factory0.1.0–0.1.5 stay on the registry forever, deploy pins included. Nothing that already resolved them changes.S01-Issuer/st0x.deploy(two files), and it pinsrain-factory = "0.1.1"withrain-factory-0.1.1/src/lib/LibCloneFactoryDeploy.solimport prefixes. It is untouched by a 0.1.6 publish and stays untouched until it deliberately bumps — at which point the missing path is a compile error, never a silent change.rain.factory.deployitself pinsrain-factory = "0.1.5", also unaffected.LibCloneFactoryDeployisrainlanguage/rainixrainix-static/src/frozen_snapshots.rs, which is not a consumer at all — the string appears in two unit-test fixtures as a path that is deliberately not a snapshot.The cost of holding this PR is real and compounding: while
rain.factorymainstill carries the deploy half, new deploy work keeps landing in the library repo. #51 is the proof — opened 2026-08-08, it modifiessrc/concrete/CloneFactory.solandsrc/lib/LibCloneFactoryDeploy.soland adds a whole new frozensrc/generated/0_1_6/snapshot, all in directories this PR deletes. Merging this first stops that accretion.QA
Discriminating tests: n/a, and that is the point of the diff. This PR deletes code and deletes every test with it; it adds no behaviour.
src/is now six interface files that declare functions, events and constants and implement nothing, so there is no behaviour a test could discriminate. The tests that exercised the deleted concrete moved torain.factory.deploywith it and run there.Mutations applied: n/a — same reason. There is no executable line left in this repo to mutate; the interfaces compile to no runtime code.
Oracle — the split plan in #46 (which files are library vs deploy, derived there from the import graph: the interfaces import nothing, the concrete imports the interfaces one-way), the Soldeer registry read directly rather than from prose (
rain-factorypublished revisions: 0.1.0, 0.1.1, 0.1.2, 0.1.3, 0.1.5 — 0.1.6 is the unpublished next slot), and the consuming repos' ownfoundry.tomland import lines. All independent of this diff.What was actually checked, and how:
forge buildclean on the interfaces-only tree (6 files, solc 0.8.25) — the cut is real: nothing left behind imports anything that left.reuse lint22/22 files compliant.forge fmt --checkclean.LibCloneFactoryDeployreturns rain.factory itself,S01-Issuer/st0x.deploy(2 files) and the rainix test fixture;st0x.deploy'sfoundry.tomlpinsrain-factory = "0.1.1"and its imports carry therain-factory-0.1.1/prefix.rain.factory.deploybuilds againstrain-factory = "0.1.5"from the registry, which is how we know the interface half publishes and consumes cleanly on its own.Category check. #46 asks for exactly one thing here: leave the
ICloneable*interface surface and move everything else out. Covered — concrete, pins, snapshots, both scripts and all four test files are gone; the four deploy-only Soldeer deps, thefs_permissions/rpc_endpoints/etherscanconfig and themanual-sol-artifactsworkflow are gone;package-release.yamlstays onrainix-autopublish. The follow-up commits also close the two gaps the vetter named on 58a938e:soldeer.lockregenerated withforge soldeer update(nowforge-stdonly),slither.config.jsonfilter path pruned, and README/CLAUDE.md rewritten to stop documenting the deploy half.Known limitation, stated rather than hidden:
forge-stdis now the only declared dependency and, withtest/removed, nothing imports it. It is kept deliberately (the review thread asked for it), butfoundry.toml's comment calling it "the test harness" is aspirational. Whether an interfaces-only repo should declare it at all is a separate call.
