Jon Chery bee9d02f01 feat(P40): contract interpolation + environment JSON schema
---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.<field>} + ${contract.<field>} 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. Existing fixture-based tests
preserved (instance.json static fixtures unaffected).
