test: pin cyclo-site-tokens.json claims on-chain via fork tests

[thedavidmeister]

Summary

canonical/cyclo-site-tokens.json is the single source of truth for every cyToken's vault, decimals, underlying, underlying decimals, receipt, and chain. cyclo.site will consume this same JSON in a follow-up PR; for now both repos stay in sync by hand and the fork test guards the on-chain claims for the values it can verify.

For every entry on the test's chain (filtered by chainId), the fork test asserts:

• vault decimals() matches the JSON
• underlying decimals() matches the JSON
• vault asset() matches the JSON's underlyingAddress

receiptAddress is not verified — older vault impls (cysFLR) don't expose receipt() as a getter. Follow-up tracked at #43.

Closes cyclofinance/cyclo.site#370 in part (decimals + asset linkage).

Test plan

• Flare suite locally: 1 test, all entries (cysFLR / cyWETH / cyFXRP) pass on a public RPC
• Arbitrum suite locally: same trie-state error the existing prod arbitrum tests hit on a non-archive RPC; CI's RPC_URL_ARBITRUM_FORK is archive-capable
• CI green

Producer note: structural CI blockers, not PR code (last run 2026-05-09, stale). (1) rainix-sol-test: all 25 failures are Arbitrum fork tests dying in setUp with 'missing trie node … change your RPC url to an archive node' — the CI ARBITRUM RPC secret is not an archive node; no assertion is ever reached. (2) rainix-sol-static: slither annotation errors inside the nested submodule lib/ethgild/lib/rain.math.fixedpoint (LibFixedPointDecimalFormat.sol 'slither-disable-end without slither-disable-start') — needs a submodule bump decision, not a source edit here. A code push cannot green this PR; leaving in the needs-human queue.

Producer note: the recorded reds were a 2026-05-09 GitHub-outage snapshot (HTTP 418 nix substituter) — empty-commit re-triggered. The re-run surfaced the real state: (1) rainix-sol-static was forge-fmt drift on the two CycloSiteTokens.prod.*.t.sol files — fixed and pushed (437b0ee, repo-pinned formatter). (2) rainix-sol-test is a STRUCTURAL env red: the fork tests' pinned block state is no longer served by CI's RPC ("missing trie node … state not available" on Arbitrum) — a re-run reproduces it identically and no code fix short of a pin/RPC decision helps; leaving it for the interactive pin work. Heads-up: rainix-HEAD sol-shell forge fmt reformats 12 files in this repo (formatter drift vs the repo's pinned flake) — use the repo's own nix develop -c forge fmt.

Producer note: 3b HAND-OFF — rainix-sol-static is red AGAIN after the 437b0ee fmt fix, now with a fmt diff in test/lib/LibCycloSiteTokens.sol (run 28742777852). This matches the formatter-drift trap flagged earlier (rainix-HEAD forge fmt vs this repo's pinned flake format differently), so a local fmt push risks ping-ponging; per back-off (one attempt per check, already spent) this is parked for a human with the repo-pinned formatter. rainix-sol-test remains the STRUCTURAL env red previously noted (Arbitrum fork state no longer served: -32000 missing trie node / metadata not found on testProdCloneFactoryBytecodeArbitrum + testProdCycloReceiptManagerArbitrum) — no code fix applies.

Blocked-infra: Two reds, both past back-off: (1) rainix-sol-test run 29051045944 — Arbitrum fork suites fail with 'missing trie node / older block with a non-archive node' (-32000); RPC_URL_ARBITRUM_FORK secret IS set but points at a pruned node; SAME failure class red on main (run 24800484874) — infra: the secret needs an archive endpoint. Flare fork suites pass. (2) rainix-sol-static — forge fmt --check diff in test/lib/LibCycloSiteTokens.sol after a prior fmt [3b-attempt]: local forge fmt output ≠ CI's (version skew; CI wants the multi-line require(...) collapsed). Both need infra/human resolution; no further producer pushes.

Design-question: Both reds are PRE-EXISTING main reds this branch cannot green, and 3b back-off is exhausted on both checks (prior attempts: a forge-fmt [3b-attempt] plus two empty-commit retriggers, 2026-05-09 and 2026-07-05). cyclo.sol main has been red since 2026-04-22 (last green 2025-12-22) and every branch run since fails the same way. (1) rainix-sol-static: Slither aborts on a VENDORED dependency, not this repo's code — 'slither-disable-end without slither-disable-start' at lib/ethgild/lib/rain.math.fixedpoint/src/lib/format/LibFixedPointDecimalFormat.sol#43 and 'Consecutive slither-disable-starts without slither-disable-end' at #37. Greening it means a cross-repo fix in rain.math.fixedpoint (then an ethgild bump), which the producer must not decide unilaterally. (2) rainix-sol-test: the Arbitrum prod-pin fork tests testProdCloneFactoryBytecodeArbitrum and testProdCycloReceiptManagerArbitrum die on 'missing trie node ... state is not available' / 'metadata is not found', with foundry's own diagnosis in the log: 'trying to fork from an older block with a non-archive node which is not supported'. No code change reaches that; it needs an archive-node Arbitrum RPC provisioned for CI (or a human ruling to re-pin FORK_BLOCK to a block a non-archive node still serves, which would move every pinned expectation in the suite). Questions for the human: who fixes the rain.math.fixedpoint slither markers, and do we provision an archive Arbitrum RPC or re-pin the fork block?

👤 human
Ruled 592b2a7: design — Misrouted: neither question needs a human, and the PR's real blocking state is the vetter's reject at this same head naming two fixable in-repo defects — the library pragma at test/lib/LibCycloSiteTokens.sol:3 (confirmed in the tree where convention wants a caret) and a bare first-party test/ import. On the Arbitrum archive red, the option space in the question is wrong: I read .github/workflows/rainix.yaml and this repo runs a hand-rolled inline job that does not call the rainix reusables at all, so the answer is neither provisioning a new RPC nor re-pinning FORK_BLOCK but adopting the reusable, where archive-aware fork RPC selection now lives. On the slither markers, who fixes it answers itself — the repo that owns the file — so that is an upstream issue to file, not a ruling to wait on.

[thedavidmeister]

Rework note @592b2a74b6de1ca9db62e9198dcd78217da1c2c8: Neither question needs a human ruling, and neither is what is actually blocking this PR. Work, in order:

1. FIX WHAT THE VETTER ALREADY NAMED. Its reject at this exact head lists two concrete in-repo defects and they are the PR's real blocking state: test/lib/LibCycloSiteTokens.sol:3 is pragma solidity =0.8.25; on a LIBRARY where the org convention requires a caret for library/abstract files (I confirmed line 3 in the tree); and CycloSiteTokens.prod.arbitrum.t.sol adds a bare first-party test/ import, which breaks consumption as a dependency. Both are yours, need no permission, and the vetter called the fork-test substance otherwise sound.

2. THE ARBITRUM ARCHIVE RED HAS A THIRD OPTION YOU DID NOT LIST, and it is the org-conventional one. Your question offered "provision an archive Arbitrum RPC" or "re-pin FORK_BLOCK". This repo's .github/workflows/rainix.yaml is a hand-rolled inline job — DeterminateSystems/nix-installer-action@v4, magic-nix-cache-action@v2, nix develop -c ${{ matrix.task }} — and does NOT call the rainix reusables at all. Shared CI belongs in rainix reusables rather than in consumers, so the move is to adopt rainlanguage/rainix/.github/workflows/rainix-sol.yaml@main (or the individual reusables) with secrets: inherit.

VERIFY THIS BEFORE ACTING ON IT, do not take it from me: I believe rainlanguage/rainix#289 merged today adds an archive-aware RPC preflight to those reusables that picks an endpoint able to serve the pinned fork block, with hardcoded archive defaults so it needs zero configuration, and that its issue #288 named cyclo.sol as one of the repos reddened by exactly this archive error. I also believe its demand scan handles this repo's raw-secret env form (RPC_URL_ARBITRUM_FORK) as well as the <NET>_RPC_URL form, and exports the selection under both. Check the merged reusable yourself and confirm it covers this repo's shape before adopting; if it does not, say so rather than adopting blind.

3. DO NOT RE-PIN FORK_BLOCK. Moving every pinned expectation in the suite to work around an RPC that cannot serve historical state is fixing the wrong thing, and it destroys the pins' value as prod assertions. That option is off the table.

4. THE SLITHER MARKERS ARE AN UPSTREAM BUG, and "who fixes it" answers itself: the repo that owns the file. FILE AN ISSUE on rain.math.fixedpoint for the mismatched markers you found at lib/ethgild/lib/rain.math.fixedpoint/src/lib/format/LibFixedPointDecimalFormat.sol — slither-disable-end without a start at Verify cyclo-site-tokens.json receiptAddress linkage on-chain #43, consecutive starts without an end at 2025 11 12 cbbtc #37 — with your log. Do not fix it here, do not vendor a patch, and do not block this PR on it. If adopting the reusable in (2) does not also resolve the static red, say so on the PR and leave it to the upstream fix.

5. Re-push and let the vetter judge it again. Note that main has been red since 2026-04-22, so a red on this branch that matches main's is not evidence about this diff — but it is also not a reason to stop, since main-red is fixable on a branch and (2) is how.
