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.

security-review/iam/ — Phase-3 IAM artifacts (authored for cross-review, NOT applied)
These are the IAM / Roles Anywhere / step-ca artifacts for the R720 agent-team aws-posture
checker (design docs/r720-agent-team-design.md D5 / §4 / §6.3 / §7 Phase 3).
Nothing here is applied to AWS. They are FILES for the mandatory GPT-4.1 IAM cross-review.
Cross-review status (2026-06-18): APPROVE, no BLOCKs. FIXes applied — aws:SourceAccount
added to the trust policy; ec2:DescribeImages removed from the permission policy (see
CROSS-REVIEW-PACKET.md header + aws-posture-readonly-policy.rationale.md). The review passing
unblocked building ../checkers/aws-posture.sh (built in this Phase-3 change set). That
checker stays PROVISIONING-GATED: it makes NO AWS call until step-ca + the Roles Anywhere
trust anchor + this role are stood up. Provisioning happens only after the review is recorded
(design §7, B3) — and a VM snapshot is taken first per feedback_ec2_replacement_snapshot.
Decision (D5): the box stays read-only and authenticates to AWS via Roles Anywhere short-lived leaf certs issued by a new internal step-ca — no long-lived AWS key on the box.
| File | Purpose |
|---|---|
CROSS-REVIEW-PACKET.md |
Start here. End-to-end trust model, least-privilege rationale, blast radius, exercised rollback, and the specific items for the reviewer. |
aws-posture-readonly-policy.json |
Least-privilege read-only permission policy (valid, applyable IAM JSON). |
aws-posture-readonly-policy.rationale.md |
Statement-by-statement rationale (IAM JSON can't carry comments). |
aws-posture-trust-policy.json |
Role trust policy — pins Roles Anywhere + the leaf subject/issuer CN + trust-anchor ARN. |
roles-anywhere-config.json |
Trust-anchor (pins step-ca root) + profile (1h session) config. |
step-ca-config-sketch.md |
Internal CA config + systemd-timer auto-renewal of the short-lived leaf. |
Per global instructions this IAM change also requires the GPT-4.1 cross-family review via
orchestrator/run.py; this directory is that review's input.
