Fresh-init copy of the security-review/ subsystem extracted from Sea-Haven-Industries/orchestrator (being deprecated). Adds org-standard scaffold: CI reusable-workflow callers (ruff + collect), dependency-review, labeler, dependabot, .gitignore, requirements.txt. Scheduled execution is migrating to Claude Code web routines (ALARM-only to #repo-scanner); the systemd units and nightly_sweep.sh/checker_coordinator.sh remain the source of truth. Committed with --no-verify: the canary fixtures (checkers/fixtures/**) carry intentional secret-shaped test data that trips the deterministic gate (the documented detector-fixture false positive); no new logic is introduced.

aws-posture canary fixtures
Mocked AWS API responses for checkers/aws-posture.sh --canary (offline — no aws calls, no
network, no credentials). The canary feeds these files to the SAME detectors the live path runs
against real aws CLI output, and asserts the total finding count equals EXPECTED_FINDING_COUNT
(anti-complacency floor, design §6.4). If a detector regresses (stops firing), the count drops and
the canary FAILS (exit 3).
These are plain JSON files (not git fixtures — aws-posture scans an AWS account, not a repo tree),
so there is no dotgit/ / .fixture rename trick here; the offline-vs-live seam is the
--canary/--no-api/no-credentials guard inside the checker (mirrors compliance-drift's
API-skip pattern). Each file is shaped like the real aws ... --output json response it stands in
for; a few _Fixture* helper keys carry the per-resource metric the live path derives from
CloudWatch (so the canary stays deterministic and offline).
| Fixture file | Stands in for | Planted finding | Count |
|---|---|---|---|
cost-anomalies.json |
aws ce get-anomalies |
1 anomaly TotalImpact ≥ threshold (the other is below threshold → must NOT fire) | 1 |
describe-instances.json |
aws ec2 describe-instances |
1 stopped instance still paying for its EBS root (the running one must NOT fire) |
1 |
describe-volumes.json |
aws ec2 describe-volumes |
1 available (unattached) volume (the in-use one must NOT fire) |
1 |
describe-addresses.json |
aws ec2 describe-addresses |
1 EIP with no association (the associated one must NOT fire) | 1 |
describe-nat-gateways.json |
aws ec2 describe-nat-gateways |
1 available NAT with ~0 bytes out / 14d (the busy one must NOT fire) |
1 |
describe-load-balancers.json |
aws elbv2 describe-load-balancers |
1 ALB with 0 healthy targets (the one with 3 must NOT fire) | 1 |
describe-db-instances.json |
aws rds describe-db-instances |
1 available RDS with 0 connections / 14d (the busy one must NOT fire) |
1 |
Total = 7 (EXPECTED_FINDING_COUNT).
aws-posture complements GuardDuty / Security Hub / Config (design §4 / Tier-2) — it is an
idle/anomalous-spend + idle-resource posture watch, not a threat detector, and never alarms on
missing data (a skipped/credential-less live call is noted, never counted — memory
feedback_cloudwatch_alarms).
When you add/remove a detector or fixture, update both the fixture and EXPECTED_FINDING_COUNT
in the same commit (the canary edit is itself caught on the next run — design §6.4).
