Build fails: `RuleEngineBase.sol` imports `CMTAT/library/RuleEngineInterfaceId.sol` and `CMTAT/library/ERC1404ExtendInterfaceId.sol` but those files don't exist anywhere in any tag/branch (v3.0.0 audited release)

Bug: CMTAT/library/RuleEngineInterfaceId and CMTAT/library/ERC1404ExtendInterfaceId import paths do not resolve

Versions

• CMTA/CMTAT tag v3.0.0 (the audited release, Wake Arena M1/M2/M3)
• CMTA/RuleEngine tag v3.0.0-rc4
• OpenZeppelin contracts v4.9.x
• OpenZeppelin contracts-upgradeable v4.9.x

Reproduction

cd /tmp && mkdir cmt-repro && cd cmt-repro
git clone --depth=1 -b v3.0.0 https://github.com/CMTA/CMTAT.git
git clone --depth=1 -b v3.0.0-rc4 https://github.com/CMTA/RuleEngine.git
cd RuleEngine && forge build

Compiler output

Error: Source "CMTAT/library/ERC1404ExtendInterfaceId.sol" not found
Error: Source "CMTAT/library/RuleEngineInterfaceId.sol" not found
   --> RuleEngineBase.sol:8:
   --> RuleEngineBase.sol:9:

Root cause

The imports in RuleEngineBase.sol reference:

• CMTAT/library/ERC1404ExtendInterfaceId.sol (singular path, "ERC1404Extend" name)
• CMTAT/library/RuleEngineInterfaceId.sol (singular path, "RuleEngine" name)

But the actual files in RuleEngine/src/modules/library/ are:

• ERC1404InterfaceId.sol (no "Extend")
• RuleInterfaceId.sol (no "Engine")

Either the Base is stale or the library library has been renamed since. I verified this consistently across all tags and branches (main and dev are at identical commits, no rebrand history).

I am using your tag pinned releases to keep the audit lineage. Without this fix, no third party can build a working integration against the audited v3.0.0 release.

I would be grateful for either:

• A patched v3.0.x point release that fixes these imports, or
• An official reply with which version pairing IS known-good

My work-in-progress: I have a working SwissDLTComplianceRule that needs to plug into RuleEngineBase. With the import bug fixed, integration tests should be straightforward.

Thanks
