Wave 3 (security-engineer, 5 files sequential):
- T-7.4: schemas/policy_check_result.schema.json (REQ-18 schema half) —
canonical shape from ARCHITECTURE.md §12.6; engine enum
[checkov,kyverno,opa]; severity enum [critical,high,medium,low,info];
result enum [pass,fail,skipped,error]. Validates as Draft 2020-12;
valid instance validates.
- T-7.5: adapters/terraform/policy/checkov_adapter.py (REQ-18 adapter
half) — Checkov JSON -> PolicyCheckResult; RULE_MAP has all 11 Checkov
rule IDs (CKV_AWS_41/45/46/20/57/24/25/1/40/7/33) mapped to the 4 L2
checks + tag/naming; emits ACDL_TAG_NAMING SKIPPED per D-043; stdlib
only; tolerates both Checkov JSON shapes. Synthetic fixture produces 3
records all valid against the schema.
- T-7.6: platform/audit_ledger_design.md (REQ-20) — three tiers (S3
Object Lock compliance 7yr, acdl-evidence hot index, DynamoDB outbox
RPO=0); spike scope (D-041) = hash chain + outbox write; v1.2 build-out
= Object Lock + JWS (KMS key, quarterly rotation) + async worker + DLQ
+ daily checkpoints. Outbox item shape, RPO/RTO table, decision trail.
- T-7.7: platform/hitl_matrix_design.md (REQ-21 design half) —
pre-execution gate model; Gitea-specific mechanics (workflow_dispatch +
gitea.actor per D-042, no Environments API); full 8-concern matrix
verbatim from §10.4; timeout 1d warn / 2d freeze; rejection -> HELD +
supersedes; CODEOWNERS routing; SoD pointer to the .py.
- T-7.8: platform/separation_of_duties.py (REQ-21 impl half) —
check(outbox_client, contract_id, current_prod_approver) -> (ok,
reason); None outbox -> no-op; equal -> SEPARATION_OF_DUTIES_VIOLATION;
distinct -> ok; route_halt_artifact stub; stdlib only (duck-typed
outbox_client). All 5 SoD cases verified.
