Fhenix shipped a non-backward-compatible FHE engine upgrade with a ciphertext state migration on 2026-04-27. The cofhejs JS package was renamed to @cofhe/sdk and bumped to 0.5.0; cofhe-hardhat-plugin awaits publication of its 0.5.0-compatible release. - cofhejs@^0.3.1 → @cofhe/sdk@^0.5.0 - cofhe-hardhat-plugin@^0.3.1 → ^0.5.0 (pending Fhenix publication)
…cts to 0.1.0 - cofhe-hardhat-plugin -> @cofhe/hardhat-plugin@^0.5.0 - @fhenixprotocol/cofhe-mock-contracts -> @cofhe/mock-contracts@^0.5.0 - @fhenixprotocol/cofhe-contracts 0.0.13 -> 0.1.0 Fhenix consolidated all SDK packages into FhenixProtocol/cofhesdk monorepo under the @cofhe/ scope as part of the v0.5.0 release.
Pins exact versions matching the protocol's mock-contracts/foundry-plugin tandem. mock-contracts@0.5.0 is incompatible with cofhe-contracts@0.1.3 (TestBed.sol uses removed FHE.decrypt; MockTaskManager has unimplemented abstract methods); 0.5.1 resolves both.

Superseded: main migrated from Hardhat to Foundry (#5) so the cofhejs/hardhat-plugin bumps in package.json are no longer applicable. Re-doing as a fresh PR against new main: only foundry.toml remappings + reineira.json cofhejs reference need updating. |

Summary
cofhejs@^0.3.1to@cofhe/sdk@^0.5.0(Fhenix renamed the JS client package)cofhe-hardhat-pluginto^0.5.0(awaiting Fhenix publication)Why
Fhenix shipped a non-backward-compatible FHE engine upgrade with a ciphertext state migration on 2026-04-27 (window 12:00–15:00 UTC). All
cofhejs/cofhesdkconsumers must move to0.5.0in the window — old engine and new engine are incompatible.reineira-codeis a Hardhat scaffold for plugin development. No source files import cofhejs directly (only the plugin uses it transitively viahre.cofhe.*), so no code rewrites are needed here — only the dependency rename.Notes
cofhe-hardhat-plugin@0.5.0is not yet published at the time this PR is opened — install will fail until Fhenix ships it. Emptytest/directories mean nothing currently runs against the plugin, so this is not blocking.@fhenixprotocol/cofhe-contractsstays at0.0.13here. Tracked separately as a pre-existing version drift.TASK_MANAGER_ADDRESSconfirmed unchanged (0xeA30c4B8b44078Bbf8a6ef5b9f1eC1626C7848D9) — no contract redeploy needed.Test plan
