The L2 thin-composition layer (composition.json + contract_resolver.py + contract schema + sample contracts) has been removed completely. The implementation was unsatisfactory and is deferred for a later redesign. - Delete: composition.json x2, contract_resolver.py, contracts/ x2, contract.schema.json - Patch: run_platform.sh now loads a pre-existing IR instance instead of resolving a contract (the downstream adapter/checkov/confidence/outbox pipeline is unchanged) - Prune: L2 entries removed from registry.json (L1 entries unchanged) - Rewrite: all 7 L1 module READMEs in plain language (no jargon), each with Resources/Inputs/Outputs/Usage/Compliance-extension-points/Versioning sections derived from interface.json - Add: 2 L2 placeholder READMEs noting the composition is under redesign - Add: modules-ir/README.md catalog index + README-TEMPLATE.md ---ci--- project: acdl phase: 17 milestone: v1.3 status: execute ---/ci---
