From bee9d02f01982bc0f953227a98a56980a7744beb Mon Sep 17 00:00:00 2001 From: Jon Chery Date: Thu, 23 Jul 2026 04:30:30 +0000 Subject: [PATCH] feat(P40): contract interpolation + environment JSON schema MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ---ci--- project: acdl phase: 40 milestone: v1.9 status: execute ---/ci--- Phase 40 — contract-interpolation (REQ-103, REQ-104, D-081): Interpolation: - core/contract_resolver.py: _expand_vars(value, context) recursively expands ${env.} + ${contract.} tokens (dotted paths supported, e.g. ${env.state_backend.bucket}). Unknown tokens raise ValueError (fail loud). Expansion is post-schema-validation, pre-IR-resolution. - resolve() accepts environment_override (D-088) — overrides the contract's environment field BEFORE schema validation so interpolation context is consistent. - env context loaded via _load_env (self-contained, works as script + package import); 'environment' alias for env 'name' so ${env.environment} resolves. Environment schema + bindings: - schemas/environment.schema.json (draft 2020-12): name, account_id, region, state_backend, network, runner_role_arn, autonomy, confidence_threshold. - core/environments/qa.json, prod.json, dr.json placeholder bindings (attested, thresholds 0.75/0.90/0.95, placeholder account_id with stderr warning at load). - core/environment_check.py: load(env_name) helper + placeholder warning. Sample contracts: - contracts/static-assets.yaml + microservice.yaml use acdl-${env.environment}-${contract.module}-${env.account_id}-${env.region} naming pattern (region + account id + environment). Tests: +35 (test_environment_schema.py, test_interpolation.py, test_sample_contracts_interpolate.py). 406 passed; run_ci.sh green; run_platform.sh --check-only green.
