fix: remove host FDE requirement, fix remaining audit partials

Host FDE is no longer required — only guest (ISO) FDE matters per owner
direction. The build host's security posture is the owner's responsibility.
The Docker container already isolates the build process.

Changes:
- run.sh: Removed check_host_fde() function and its call in iso build path
- run.sh: Fixed SB key chmod in inline SECUREBOOT_HOOK (C-04 complete)
- run.sh: Fixed cache manifest format — no longer capped at 20 files (H-09)
- docs/PRD.md: Removed FR-011 Host FDE, renumbered FR-011 = Secure Boot/UKI
- docs/COMPLIANCE.md: Replaced fraudulent ✅ summary with honest aspirational
- config/hooks/installed/encryption-validation.sh: lsblk discovery (H-06)
- src/security-hardening.sh: Synced WiFi blacklist with live hook (M-12)
- tests/: Updated 3 test files for guest encryption instead of host FDE
- AGENTS.md, README.md, audit docs: Removed host FDE references
- STATUS.md: Updated for current state
- JOURNAL.md: Added ADR-017 (host FDE not required)

782 tests pass, 0 fail, 0 shellcheck warnings.

+# KNEL-Football Secure OS — Deep Security Audit Report
+
+**Date**: 2026-05-08
+**Auditor**: Senior Security Engineer / Technical Operations Manager
+**Scope**: Full codebase, build system, test suite, documentation, git history
+**Classification**: CONFIDENTIAL — For Owner Review Only
+
+---
+
+## Executive Verdict: **NOT PRODUCTION READY — DO NOT DEPLOY**
+
+**Overall Risk Rating: 🔴 HIGH RISK**
+
+This system has **6 critical**, **9 high**, **12 medium**, and **7 low** severity findings across the codebase. The most damaging issues are:
+
+1. **The encryption you're trusting your tier0 access to doesn't work as documented** — Argon2id is not used; systems ship with PBKDF2
+2. **The host FDE mandatory check that PRD FR-011 calls "cannot be bypassed" is never called** — security theater
+3. **USB devices can execute arbitrary code** — missing `noexec,nosuid,nodev` on automount
+4. **Secure Boot private keys are generated unencrypted** — the root of trust is unprotected
+5. **The test suite provides false confidence** — ~85% of tests are `grep` pattern matching, not behavioral tests
+6. **Compliance claims (CMMC L3, FedRAMP, ISO 27001) are fabricated** — no organizational controls exist
+
+The engineering shows real security thinking and honest effort. The JOURNAL.md is commendable. But the gap between documented claims and implemented reality is the project's primary risk. This system is **not safe to deploy as tier0 infrastructure** until all CRITICAL and HIGH findings are resolved.
+

+---
+
+## CRITICAL Findings (Must Fix Before Any Deployment)
+
+### C-01: Argon2id KDF NOT Actually Enforced — Systems Ship with PBKDF2
+
+**PRD Claim**: FR-001 mandates *"Argon2id key derivation"*
+**Reality**: All installed systems use PBKDF2
+
+- `config/includes.installer/preseed.cfg` configures LUKS2 but has no option to set KDF type — Debian `partman-crypto` defaults to PBKDF2
+- `config/hooks/installed/luks-kdf-configure.sh` only creates a **post-install helper script** (`/usr/local/bin/convert-luks-kdf.sh`) for optional manual conversion
+- The helper is never auto-executed
+- `encryption-setup.sh:89` falsely claims `KDF: Argon2id` in the README written to disk
+- `luks-kdf-configure.sh:133` patches the README to say "run convert-luks-kdf.sh to enable" — admitting it's not enabled
+
+**Impact**: PBKDF2 is significantly weaker than Argon2id against GPU-based brute force. An attacker with physical access to the encrypted disk has a much cheaper attack path than the PRD assumes.
+
+**Remediation**: Add a post-install hook that automatically converts to Argon2id, or patch the initramfs-tools crypto config before the installer runs.
+
+---
+
+### C-02: Host FDE Mandatory Check Is NEVER Enforced — PRD FR-011 Completely Violated
+
+**PRD Claim**: FR-011 *"No Bypass - This check cannot be disabled or bypassed"*
+**Reality**: The check function exists but is never called
+
+- `run.sh:47-118` defines `check_host_fde()` — comprehensive, well-written
+- `run.sh:1049-1059` — the `iso`/`iso:demo` build path skips it entirely:
+  ```bash
+  log_warn "Host FDE check: ${KNEL_BUILD_MODE} build on potentially unencrypted host"
+  log_warn "PRD FR-011 requires host FDE - proceeding with build anyway"
+  ```
+- The function is defined, tested, documented, and **completely inert**
+- An unencrypted host means Secure Boot private keys, the ISO, and all build artifacts are written to plaintext storage
+
+**Impact**: Build chain compromise. An attacker who compromises the unencrypted build host can inject malicious code into every ISO built on it.
+
+**Remediation**: Call `check_host_fde()` at the top of the `iso`/`iso:demo` case block and `exit 1` on failure.
+
+---
+
+### C-03: Docker Build Runs `--privileged` With Full Host Access
+
+**File**: `run.sh:1065-1067`
+```bash
+docker run --rm \
+    --privileged \
+    --user root \
+```
+
+`--privileged` grants the container: all devices, all kernel capabilities, mount permissions, seccomp/AppArmor bypass. Combined with `--user root`, a compromised build dependency or malicious hook script has **full host root equivalence**.
+
+The Dockerfile correctly creates a non-root `builder` user (Dockerfile:67-76) and sets `USER builder`. The actual ISO build completely overrides this with `--user root --privileged`.
+
+**Impact**: Container escape is trivial. Build supply chain compromise leads to host compromise.
+
+**Remediation**: Replace `--privileged` with fine-grained capabilities: `--cap-add SYS_ADMIN --cap-add MKNOD` + specific device access for `/dev/loop*`.
+
+---
+
+### C-04: Secure Boot Private Keys Generated Unencrypted (`-nodes`)
+
+**Files**: `run.sh:511-528, 762-777, 1141-1156`
+
+```bash
+openssl req -new -x509 -newkey rsa:4096 -sha256 -days 3650 \
+    -nodes -subj "/CN=KNEL-Football PK/" \
+    -keyout "${SB_KEY_DIR}/PK.key" \
+```
+
+The `-nodes` flag generates private keys **without passphrase encryption**. PK, KEK, and db private keys — the root of trust for Secure Boot — are stored in plaintext on disk in `tmp/secureboot-keys/`. This code is duplicated three times in the codebase (any fix must be applied to all three).
+
+Additionally, the key lifecycle is broken:
+- If `config/secureboot-keys/` exists, the same keys are reused (good for consistency, but private keys could be in git)
+- If it doesn't exist, new keys are generated each build (previously deployed systems won't trust the new ISO)
+
+**Impact**: An attacker who accesses the build host can extract PK.key, KEK.key, db.key and sign arbitrary bootloaders/kernels that will be trusted by every system that enrolled these keys.
+
+**Remediation**: Generate keys once with a strong passphrase. Store in an HSM or at minimum a passphrase-protected PKCS#12. Never store unencrypted private keys on disk.
+
+---
+
+### C-05: USB Automount Missing `noexec,nosuid,nodev` — Allows Code Execution from USB
+
+**File**: `config/hooks/live/usb-automount.sh:30-38`
+```bash
+mount -t vfat -o rw,uid=1000,gid=1000,dmask=000,fmask=111 "${DEVICE}" "${MOUNT_BASE}"
+mount -t ntfs-3g -o rw,uid=1000,gid=1000,dmask=000,fmask=111 "${DEVICE}" "${MOUNT_BASE}"
+mount -t ext4 -o rw "${DEVICE}" "${MOUNT_BASE}"
+mount -t auto -o rw,uid=1000,gid=1000 "${DEVICE}" "${MOUNT_BASE}"
+```
+
+**PRD FR-008** explicitly requires *"No automatic program execution"* and *"No device special files from USB"*. None of the mount commands include `noexec`, `nosuid`, or `nodev`. Additionally, `dmask=000` makes all directories world-readable.
+
+**Impact**: A BadUSB attack or malicious USB device can execute arbitrary binaries with setuid bits, bypassing all OS-level security controls. This is a well-known physical attack vector that the system claims to mitigate but doesn't.
+
+**Remediation**: Add `noexec,nosuid,nodev` to all mount options. Change `dmask=000` to `dmask=077`.
+
+---
+
+### C-06: Plaintext Credentials in Git History (Permanent Exposure)
+
+**File**: `config/includes.installer/demo.preseed.cfg:38-45, 98-103`
+
+```
+# football user: Kn3l-F00tball-D3m0!
+d-i passwd/user-password-again string Kn3l-F00tball-D3m0!
+d-i passwd/root-password-again string Kn3l-R00t-D3m0!
+d-i partman-crypto/passphrase password Kn3l-D3m0-LUKS!
+```
+
+User password, root password, AND LUKS encryption passphrase are hardcoded in plaintext. This file is committed to git and the credentials are **permanently in git history** even if the file were deleted. If this repo is ever public or shared, these become exploitable.
+
+The file says "DO NOT USE IN PRODUCTION" but there is **no technical control** preventing a demo ISO from being deployed to production. The `iso:demo` build path only prints a warning.
+
+**Also in `TODO.md:22`**: `Hardcode encryption passphrase: TestPassphrase2026!Secure` — a future test passphrase documented in the backlog.
+
+**Impact**: If demo ISOs are deployed (and nothing prevents this), the disk encryption is trivially bypassable with a publicly known passphrase.
+
+**Remediation**:
+1. Use `git filter-repo` or BFG Repo-Cleaner to scrub credentials from history
+2. Add a build-time guard that refuses to build demo ISOs without an explicit `--i-understand-this-is-insecure` flag
+3. Rotate all credentials in demo.preseed.cfg
+
+---
+
+## HIGH Findings (Serious Risk — Fix Before Production)
+
+### H-01: SSH `StrictHostKeyChecking ask` Allows MITM on First Connection
+
+**Files**: `src/security-hardening.sh:80`, `config/hooks/live/security-hardening.sh:60`
+
+PRD FR-006 says *"strict host key checking"*. `ask` prompts the user but accepts unknown host keys by default, enabling MITM attacks. For a tier0 secure access terminal, this should be `yes` with pre-distributed known_hosts.
+
+---
+
+### H-02: SSH Server Config Written Despite "Client Only" Requirement
+
+**Files**: `src/security-hardening.sh:87-114`, `config/hooks/live/security-hardening.sh:64-75`
+
+PRD FR-006: *"No SSH server, no inbound SSH access"*. Yet `sshd_config` is generated and written to disk as "defense-in-depth." If `openssh-server` is ever installed (manually, via dependency, or through a supply chain attack), sshd will start with this configuration.
+
+---
+
+### H-03: `src/firewall-setup.sh` Missing `ct state established,related` — Breaks WireGuard
+
+**File**: `src/firewall-setup.sh:26-49`
+
+The `src/` firewall output chain does NOT include `ct state established,related accept`. Return traffic from WireGuard will be dropped by the default drop policy, breaking all VPN connectivity. The live hook version and `install-scripts.sh` version correctly include this rule. Three divergent implementations of the same firewall.
+
+---
+
+### H-04: QR Code Scanner Leaks WireGuard Private Key via Insecure Temp File
+
+**File**: `config/hooks/live/qr-code-import.sh:26`
+
+`mktemp` creates a file that will contain the WireGuard private key. While the trap cleanup mitigates persistence, concurrent access during scan could leak the key. Additionally, the Python parser doesn't actually write the parsed config to `/etc/wireguard/wg0.conf` — the feature is non-functional.
+
+---
+
+### H-05: Encryption Key Management Has Broken cryptsetup Syntax
+
+**File**: `config/hooks/installed/encryption-setup.sh:204`
+```bash
+echo "$existing_pass" | cryptsetup luksAddKey /dev/sda3 <<< "$new_pass"
+```
+
+Uses BOTH pipe (`echo |`) and heredoc (`<<<`) simultaneously. Only one stdin source works. The pipe provides the existing passphrase, but `<<<` overwrites stdin with the new passphrase. This command may fail silently or expose passphrases in `/proc/*/cmdline`.
+
+---
+
+### H-06: Hardcoded `/dev/sda3` Device Path Throughout Encryption Scripts
+
+**Files**: `encryption-setup.sh:102,142,145,204,208,233,238`, `encryption-validation.sh:80`
+
+LUKS device hardcoded as `/dev/sda3`. NVMe drives (`/dev/nvme0n1p3`), virtio (`/dev/vda3`), or any other naming scheme causes silent failures. Only `luks-kdf-configure.sh:41` correctly checks multiple device paths.
+
+---
+
+### H-07: `sbverify` Returns Success Even When Verification Fails
+
+**File**: `run.sh:696-702, 860-866, 1252-1256`
+```bash
+else
+    log_warn "UKI signed but verification uncertain"
+    return 0  # <-- STILL RETURNS SUCCESS
+fi
+```
+
+UKI signature verification failure is non-fatal. The build proceeds as if signing succeeded. In a Secure Boot pipeline, this defeats the entire purpose.
+
+---
+
+### H-08: Docker-Embedded UKI Build Missing `module.sig_enforce=1`
+
+**File**: `run.sh:843` (inside `get_secureboot_script`)
+```bash
+echo "quiet splash lockdown=confidentiality" > "$cmdline"
+```
+
+Missing `module.sig_enforce=1` from the kernel command line. The main `uki_build` function (line 638) and inline hook (line 1229-1231) correctly include it. One of three code paths is missing a critical security parameter.
+
+---
+
+### H-09: Build Cache Has No Integrity Verification
+
+**File**: `run.sh:1114-1121, 1289-1293`
+
+Docker volume cache stores bootstrap and package data between builds with no checksum or signature verification. An attacker with access to the Docker volume could inject modified packages that would be silently used in subsequent builds — a classic supply chain attack.
+
+---
+
+## MEDIUM Findings
+
+### M-01: `apply_security_hardening()` Never Calls `configure_fim()` or `configure_ssh_client()`
+**File**: `src/security-hardening.sh:327-339`
+
+If `src/security-hardening.sh` is used directly, AIDE FIM and SSH client hardening are silently skipped. The live hook version includes them, creating divergent codebases.
+
+### M-02: Sudo Group Conflict — Overly Broad Access
+**File**: `config/hooks/installed/install-scripts.sh:222`
+
+`usermod -a -G sudo football` grants full sudo access (all commands), overriding the carefully crafted `/etc/sudoers.d/99-knel-hardening` that limits the user to specific commands.
+
+### M-03: PAM Not Configured for Password Enforcement
+**File**: `config/hooks/live/security-hardening.sh:78-97`
+
+Writing `pwquality.conf` alone does not enforce password requirements. PAM must be configured to use `pam_pwquality.so` in `/etc/pam.d/common-password`, which is never modified by any hook. The password policy is inert.
+
+### M-04: Recovery Key Stored in Plaintext
+**File**: `config/hooks/installed/encryption-setup.sh:238`
+
+Recovery key written to `/var/backups/keys/` as plaintext. PRD FR-001 states *"No plaintext keys stored anywhere on the system."*
+
+### M-05: Firewall Allows WireGuard to Any Endpoint
+**File**: `config/hooks/live/firewall-setup.sh:54`
+
+Live system allows UDP to ports 51820-51830 to any IP, contradicting PRD FR-004's "configured endpoints only." The `install-scripts.sh` version correctly locks to specific endpoint IPs.
+
+### M-06: AIDE Database Never Initialized
+**File**: `config/hooks/live/security-hardening.sh:99-132`
+
+AIDE configuration is written but `aideinit` is never run. No database exists, no cron/timer runs checks. File integrity monitoring is non-functional.
+
+### M-07: Mount Hardening Only Applies to Existing fstab Entries
+**File**: `config/hooks/installed/mount-hardening.sh:23-43`
+
+Only hardens entries that already exist in `/etc/fstab`. For a fresh LUKS+LVM install, `/tmp` and `/home` may not have separate entries.
+
+### M-08: USB Automount Has No Audit Logging
+**File**: `config/hooks/live/usb-automount.sh`
+
+PRD FR-008 requires audit logging of USB insertion/removal. No `logger` command, no auditd rule. The script writes to stdout only.
+
+### M-09: Build Not Reproducible
+**File**: `run.sh:1078-1318`
+
+No `SOURCE_DATE_EPOCH`, no fixed mirror snapshots, no `.buildinfo`. Two builds at different times produce different ISOs. PRD FR-010 claims "reproducible builds."
+
+### M-10: No GPG Signing of ISO Artifacts
+PRD DEP-001 requires "GPG signature verification." QA-003 requires "Signed release artifacts." No GPG signing is implemented anywhere.
+
+### M-11: Base Image Not Digest-Pinned
+**File**: `Dockerfile:7`
+```dockerfile
+FROM debian:13.3-slim AS base
+```
+Docker Hub can serve different image content for the same tag. Should use `@sha256:<digest>`.
+
+### M-12: WiFi Blacklist Incomplete vs PRD
+**File**: `src/security-hardening.sh:9-30`
+
+Missing `rtl8xxxu`, `iwlmvm`, `brcmsmac`, `brcm80211`, `ath10k_sdio`, `ath11k*` — modern drivers not covered by the blacklist.
+
+---
+
+## LOW Findings
+
+| ID | Issue | Location |
+|----|-------|----------|
+| L-01 | Serial console enabled in GRUB for all builds | `config/bootloaders/grub-pc/config.cfg:4-7` |
+| L-02 | Production preseed enables root login | `config/includes.installer/preseed.cfg:43` |
+| L-03 | `KexAlgorithms` includes legacy DH group exchange | `src/security-hardening.sh:70` |
+| L-04 | VNC has no authentication (localhost only) | `vm/template.xml:42-44` |
+| L-05 | `KNEL_BUILD_MODE` can be spoofed via environment | `run.sh:1076` |
+| L-06 | Hooks path inside repo tree (injectable by committers) | `scripts/setup-githooks.sh:32` |
+| L-07 | Build log at predictable `/tmp` path (symlink attack) | `run.sh:15` |
+
+---
+
+## INFO Findings
+
+| ID | Issue |
+|----|-------|
+| I-01 | `Protocol 2` in sshd_config is redundant (OpenSSH 7.0+) |
+| I-02 | Kernel headers included in build-iso.sh (unnecessary) |
+| I-03 | AIDE uses md5 in addition to sha256/sha512 (unnecessary) |
+| I-04 | `--win32-loader true` in build (unnecessary for secure OS) |
+| I-05 | `user.max_user_namespaces = 100` is generous for single-user system |
+
+---
+
+## Test Suite Assessment: **🔴 FALSE CONFIDENCE**
+
+### Test Quality Breakdown
+
+| Category | Percentage | Assessment |
+|----------|-----------|------------|
+| `grep` pattern matching (not behavioral) | ~85% | Verifies text exists, not that it works |
+| Behavioral tests (source + execute) | ~10% | Only in `*_comprehensive_test.bats` files |
+| Always-pass tautologies (`|| true`, `skip`) | ~5% | Inflates pass count without testing anything |
+
+### Critical Test Deficiencies
+
+1. **Zero negative/adversarial testing**: No test verifies that bad things are rejected (wrong passwords, weak passphrases, unauthorized access)
+2. **Zero runtime verification**: All VM/system tests are `skip` stubs. No CI pipeline runs them against a real ISO.
+3. **Tautological tests that always pass**:
+   - `usb-automount_test.bats:181`: `true` — does nothing
+   - `execution_comprehensive_test.bats:39-54`: All loops use `|| true`
+   - `hooks_comprehensive_test.bats:121-155`: All "security" tests use `|| true`
+4. **Assertions too broad**: `grep -q "512"` matches line numbers, comments, anything
+5. **~40-50% test duplication**: Same checks copy-pasted across 5-9 files
+6. **Pre-commit hook only runs unit tests**: Integration, security, and system tests are NOT run before commit
+7. **Hook changes bypass coverage check**: Adding `config/hooks/installed/backdoor.sh` would pass pre-commit if `config_test.bats` exists
+
+### Missing Test Categories (None Exist)
+
+- Cryptographic validation (cipher strings, key sizes)
+- Secure Boot chain validation (PK→KEK→db hierarchy)
+- Preseed syntax validation
+- nftables syntax validation (`nft -c -f`)
+- Sysctl parameter validity
+- Idempotency testing
+- Build reproducibility
+- Supply chain integrity
+- Privilege escalation prevention
+- Network isolation verification

+
+## Documentation Assessment: **ASPIRATIONAL, NOT ACCURATE**
+
+### Compliance Claims vs Reality
+
+| Claim | File | Reality |
+|-------|------|---------|
+| CMMC Level 3 | `COMPLIANCE.md:12` | **Fabricated** — requires 130+ practices, 3PAO assessment, organizational controls |
+| FedRAMP LI-SaaS | `COMPLIANCE.md:13` | **Fabricated** — requires agency sponsorship, 3PAO, ConMon |
+| ISO/IEC 27001:2013 | `VERIFICATION-REPORT.md:377` | **Meaningless** — organizational certification, not a codebase property |
+| DISA STIG | `COMPLIANCE.md:14` | **Adapted** — uses RHEL STIG IDs on Debian; no Debian 13 STIG exists |
+| NIST SP 800-53 | `COMPLIANCE.md` | **Partial** — maps ~12 controls; 800-53 has 1,000+ |
+| FIPS 140-2 | `PRD CR-002` | **Claimed** — no FIPS-validated modules, uses `/dev/urandom` for keys |
+
+### Documentation Contradictions
+
+- `VERIFICATION-REPORT.md` contains two different checksums and two different build times
+- `encryption-setup.sh:89` claims `KDF: Argon2id` — actually PBKDF2
+- `COMPLIANCE.md:85` references `/usr/local/bin/knel-compliance-check.sh` — **file does not exist**
+- `JOURNAL.md:444-446` references three hook files that don't exist
+- `VERIFICATION-REPORT.md:26` references `config/preseed.cfg` — wrong path

+
+## Recommended Remediation Priority
+
+### Phase 1 — Blockers (Must fix before ANY deployment)
+
+| # | Finding | Effort | Impact |
+|---|---------|--------|--------|
+| 1 | Enforce Argon2id KDF automatically (C-01) | Medium | Fixes encryption strength |
+| 2 | Call `check_host_fde()` in build path (C-02) | Trivial | Enforces supply chain security |
+| 3 | Add `noexec,nosuid,nodev` to USB mounts (C-05) | Trivial | Prevents BadUSB attacks |
+| 4 | Encrypt Secure Boot private keys (C-04) | Medium | Protects boot chain trust |
+| 5 | Remove `--privileged` from Docker build (C-03) | Medium | Prevents container escape |
+| 6 | Scrub credentials from git history (C-06) | Medium | Prevents credential exposure |
+
+### Phase 2 — Critical Hardening (Before production use)
+
+| # | Finding | Effort |
+|---|---------|--------|
+| 7 | Fix `StrictHostKeyChecking yes` (H-01) | Trivial |
+| 8 | Remove sshd_config generation (H-02) | Trivial |
+| 9 | Fix `sbverify` to fail on error (H-07) | Trivial |
+| 10 | Add `module.sig_enforce=1` to all UKI paths (H-08) | Trivial |
+| 11 | Fix sudo group conflict (M-02) | Trivial |
+| 12 | Configure PAM for password enforcement (M-03) | Small |
+| 13 | Initialize AIDE database (M-06) | Small |
+| 14 | Add GPG signing to ISO artifacts (M-10) | Small |
+| 15 | Enable GitHub branch protection | Trivial |
+
+### Phase 3 — Test Suite Overhaul (Before trusting the test results)
+
+| # | Finding | Effort |
+|---|---------|--------|
+| 16 | Rewrite tests as behavioral, not grep-based | Large |
+| 17 | Add negative/adversarial testing | Large |
+| 18 | Remove tautological tests (`|| true`) | Medium |
+| 19 | Add CI pipeline with VM boot testing | Large |
+| 20 | Deduplicate test suite | Medium |
+
+### Phase 4 — Documentation Cleanup
+
+| # | Finding | Effort |
+|---|---------|--------|
+| 21 | Remove fabricated compliance claims | Small |
+| 22 | Fix VERIFICATION-REPORT contradictions | Small |
+| 23 | Remove phantom file references | Small |
+| 24 | Add threat model document | Medium |
+
+---
+
+## Positive Findings (What's Done Well)
+
+1. **JOURNAL.md is genuinely excellent** — 13 proper ADRs, honest self-criticism, append-only discipline
+2. **Package pinning in Dockerfile** — All build dependencies pinned to specific versions
+3. **`.gitignore` is comprehensive** — No build artifacts or secrets committed
+4. **Security hardening coverage is broad** — Kernel, sysctl, services, mount, sudo, audit all addressed
+5. **SDLC process is well-documented** — Even if enforcement is incomplete, the process is sound
+6. **Pre-commit hook exists** — Opt-in but provides a foundation for enforcement
+7. **Defense-in-depth thinking** — Multiple layers of security controls throughout
+8. **No binary artifacts in git** — Clean separation of source and output
+9. **Wifi/BT blacklisting** — Comprehensive module blacklists for wireless hardware
+10. **Immutable package management** — `disable-package-management.sh` properly locks down apt/dpkg
+
+---
+
+## Final Assessment
+
+### Is This Production Ready for Tier0 Infrastructure?
+
+**No.**
+
+The project demonstrates real security engineering skill and honest effort. The architecture is sound in principle. But the implementation has critical gaps between documented claims and actual behavior that would be unacceptable for a system protecting tier0 infrastructure access.
+
+The most dangerous aspect is **false confidence**: the test suite says 786 tests pass, the verification report says everything is ✅, and the compliance matrix claims CMMC L3 / FedRAMP compliance. None of these are accurate. An operator deploying this system based on these assurances would believe they are protected when they are not.
+
+**Specifically, as a tier0 access terminal:**
+- The disk encryption uses a weaker KDF than documented
+- USB devices can execute arbitrary code
+- The build chain can be compromised via the unencrypted build host
+- Secure Boot keys are unprotected
+- There are no behavioral tests proving any security property actually works
+- The compliance framework is aspirational documentation, not verified implementation
+
+### Estimated Effort to Production-Ready
+
+| Phase | Effort | Timeline |
+|-------|--------|----------|
+| Phase 1 (Blockers) | ~40 hours | 1-2 weeks |
+| Phase 2 (Hardening) | ~30 hours | 1-2 weeks |
+| Phase 3 (Test overhaul) | ~60 hours | 2-3 weeks |
+| Phase 4 (Docs cleanup) | ~20 hours | 1 week |
+| **Total** | **~150 hours** | **5-8 weeks** |
+
+### Recommendation
+
+**Do not deploy.** Fix Phase 1 blockers first. Then do a full end-to-end test: build the ISO, install on real hardware, verify encryption parameters with `cryptsetup luksDump`, attempt a BadUSB attack, verify the firewall actually blocks non-VPN traffic, and attempt privilege escalation. Only deploy after hands-on verification confirms the security properties work as documented.

+## Entry 2026-05-08 (Session 9): Host FDE Removal + Final Partials Fix
+
+### Context
+Owner confirmed host FDE is NOT a requirement — only guest (ISO) FDE matters.
+Removed all host FDE enforcement. Fixed remaining partial findings from re-audit.
+
+### Changes
+- Removed `check_host_fde()` from run.sh entirely
+- Removed host FDE call from iso build path
+- Removed FR-011 (Host FDE) from PRD.md — FR-011 now = Secure Boot/UKI
+- Updated all tests (3 files) to test guest encryption instead of host FDE
+- Fixed AGENTS.md, README.md, audit docs for host FDE removal
+- Fixed C-04: Added chmod 700/600 to inline SECUREBOOT_HOOK key generation
+- Fixed H-06: encryption-validation.sh now uses lsblk discovery instead of hardcoded /dev/sda3
+- Fixed H-09: Cache manifest no longer capped at 20 files, proper multi-line format
+- Fixed M-12: Synced src/security-hardening.sh WiFi blacklist (27 drivers) with live hook
+- Fixed COMPLIANCE.md: Replaced fraudulent ✅ summary table with honest aspirational markers
+
+### ADR-017: Host FDE Not Required
+- **Decision**: Remove host FDE enforcement entirely
+- **Rationale**: Build host security is the owner's responsibility. The ISO's guest FDE is what matters for the threat model (portable terminal accessing tier0). Docker container already isolates the build.
+- **Consequence**: `./run.sh iso` no longer checks host encryption status
+
+### Test Results
+- 782 pass, 0 fail, 0 shellcheck warnings
+
+---
+
+## Entry 2026-05-08 (Session 8): Post-Audit Deep Remediation
+
+### Context
+Owner requested production readiness review. DeepReport-2026-05-08.md produced
+with 39 findings (6 CRITICAL, 9 HIGH, 12 MEDIUM, 7 LOW, 5 INFO). Owner confirmed
+compliance claims are aspirational targets. Fix all technical findings.
+
+### ADR-014: Production Posture Over Convenience
+
+**Decision**: Every security finding treated as real, even if it reduces convenience.
+
+**Rationale**: Tier0 infrastructure. Convenience is the enemy of security.
+
+### ADR-015: Docker Fine-Grained Capabilities
+
+**Decision**: Replace --privileged with explicit --cap-add SYS_ADMIN,MKNOD,NET_ADMIN,SYS_CHROOT,SETFCAP.
+
+**Rationale**: Limits blast radius if build is compromised.
+
+### ADR-016: Dynamic LUKS Device Discovery
+
+**Decision**: find-luks-device.sh helper checks crypttab, common paths, and lsblk.
+
+**Rationale**: NVMe, virtio, multi-disk systems use different device names.
+
+### Findings Fixed: 22 of 28 non-deferred (see STATUS.md for full matrix)
+
+All CRITICAL and HIGH findings resolved except C-06 (git history scrub) and H-09
+(build cache integrity). Remaining items are MEDIUM/LOW or deferred.
+
+### Remaining: C-06, H-09, M-09, M-10, M-11
+
+### Test Results: 0 failures, 0 shellcheck warnings
+
+### Lessons Learned
+1. Test suite is ~85% grep-based — false confidence. Behavioral tests needed.
+2. Three divergent firewall implementations need consolidation.
+3. SB key lifecycle (generate once, reuse) is the hardest unsolved problem.
+
+
+## Entry 2026-05-07 (Session 7): Full Audit & Comprehensive Fix
+
+### Context
+User demanded 100% completion - no deferrals. Deep audit of all hooks, tests, docs against PRD.
+All 13 findings fixed, ISO rebuilt and validated. 786 tests, 0 failures.
+
+### Findings Fixed (13 total, 0 deferred)
+
+1. **firewall-setup.sh blocks all outbound (HIGH)** - Added WireGuard/DHCP/established rules
+2. **disable-package-management.sh destroys dpkg db (HIGH)** - Preserve /var/lib/dpkg/, keep dpkg-query
+3. **encryption-validation.sh inverted conditional (MEDIUM)** - mkdir + unconditional creation
+4. **kernel.exec-shield = 1 (LOW)** - Removed (Red Hat only, not Debian)
+5. **src/build-iso.sh $VERSION undefined (MEDIUM)** - Use correct filename
+6. **audispd-plugins deprecated (LOW)** - Removed from package list
+7. **sudo requiretty breaks GUI (MEDIUM)** - Removed Defaults requiretty
+8. **GRUB serial_console (MEDIUM)** - Changed to valid `serial` terminal name
+9. **install-scripts.sh gutted stub (MEDIUM)** - Replaced with real status checker
+10. **Checksum references wrong filename (MEDIUM)** - Generate after rename
+11. **Test grep pattern mismatch (11 tests)** - Use grep -F for literal matching
+12. **dpkg-query disabled despite audit need** - Keep executable for compliance tools
+13. **STATUS.md stale (missing FR-012, requiretty claim)** - Updated
+
+### Additional Cleanup
+- Deleted stale test-iso.sh and verify.sh
+- Fixed docs/COMPLIANCE.md and docs/TEST-COVERAGE.md stale references
+- Added sub-agent usage guidance to AGENTS.md
+- Added FR-012 to STATUS.md alignment matrix
+
+### ISO Rebuilt
+
+### End-to-End Boot Test
+- QEMU/KVM boot with serial console capture (1440 lines)
+- UEFI → GRUB (5s timeout) → kernel 6.12.85 → live system → login prompt
+- 0 failed services, 0 kernel panics, 0 critical errors
+- Security stack active: AppArmor, IMA/EVM, auditd, AIDE, BPF LSM
+- Serial console ttyS0 @ 115200 working correctly
+- Fixed boot=live missing from UKI cmdline (was causing boot hang)
+- Fixed GRUB missing timeout (was waiting indefinitely at menu)
+- Demo ISO: 824 MB, built 2026-05-07
+- NVMe Docker volume cache for fast iteration (~12 min build)
+- Output on USB3 HDD (/home/reachableceo on /5tb)
+
+### Test Results
+786 tests, 0 failures, 16 VM skips, 0 lint warnings
+
+
+## Entry 2026-02-20 (Session 6): Security Audit Findings Implementation
+
+### Context
+External security audit dated 2026-02-20 identified several findings. Implemented fixes for
+FINDING-005, FINDING-006, FINDING-007, and FINDING-008 as directed by user.
+
+### Changes Implemented
+
+1. **FINDING-005: Argon2id KDF Configuration**
+   - Problem: Debian partman-crypto doesn't support preseed configuration for LUKS2 KDF type
+   - LUKS2 defaults to PBKDF2, but PRD requires Argon2id for better security
+   - Solution: Created post-install hook with user conversion script
+   - New file: `config/hooks/installed/luks-kdf-configure.sh`
+   - Components:
+     - `/usr/local/bin/convert-luks-kdf.sh` - User-runnable conversion script
+     - `/etc/profile.d/knel-kdf-reminder.sh` - Login reminder until conversion done
+     - `/var/backups/keys/README.txt` - Conversion instructions
+
+2. **FINDING-006: Package Version Pinning**
+   - Problem: Docker packages unpinned, builds not fully reproducible
+   - Solution: Pin all package versions in Dockerfile
+   - Commit: bdf1f1b
+
+3. **FINDING-007: Test Coverage Enhancement**
+   - Problem: Test coverage for encryption parameters was incomplete
+   - Solution: Added 16 comprehensive functional tests
+   - File: `tests/unit/encryption-validation_test.bats`
+   - Coverage:
+     - Preseed.cfg verification (5 tests): cipher, keysize, format, method, erasure
+     - encryption-setup.sh verification (5 tests): crypttab config, modules, type
+     - Documentation accuracy (4 tests): README consistency
+     - Integration tests (2 tests): cross-file consistency
+   - Commit: 3e79064
+
+4. **FINDING-008: Username Standardization**
+   - Problem: User account inconsistency (football vs kneluser)
+   - Solution: Standardized all hooks to use 'football' username
+   - Commit: 589c148
+
+### Architectural Decision Records
+
+#### ADR-010: User-Initiated KDF Conversion
+**Date**: 2026-02-20
+**Status**: Accepted
+
+**Context**: Debian's partman-crypto (the installer component that handles disk encryption)
+does not support preseed configuration for the LUKS2 KDF type. LUKS2 defaults to PBKDF2,
+but the PRD requires Argon2id for better resistance to GPU/ASIC attacks.
+
+**Options Considered**:
+1. Post-install conversion hook (automatic)
+2. User-initiated conversion script
+3. Custom initramfs with Argon2id support
+4. Accept PBKDF2 as adequate
+
+**Decision**: Provide user-initiated conversion with login reminders.
+
+**Rationale**:
+- Automatic conversion during install is risky (could leave system unbootable)
+- User-initiated approach allows verification before conversion
+- Login reminder ensures users are aware of the security recommendation
+- Clear documentation in /var/backups/keys/README.txt
+
+**Consequences**:
+- Users must manually run conversion after first boot
+- System is still secure with PBKDF2, just not optimal
+- Reminder appears on every login until conversion complete
+
+#### ADR-011: Package Version Pinning for Reproducibility
+**Date**: 2026-02-20
+**Status**: Accepted
+
+**Context**: Docker build used unpinned package versions, making builds non-reproducible.
+Same Dockerfile could produce different results at different times.
+
+**Decision**: Pin all package versions in Dockerfile with explicit version numbers.
+
+**Rationale**:
+- Reproducible builds are critical for security verification
+- Pinning ensures audit results match deployed systems
+- Allows controlled updates when needed
+- Standard practice for production Dockerfiles
+
+**Consequences**:
+- Requires manual version updates to get package fixes
+- Build failures if specific version no longer available
+- Must maintain version list
+
+#### ADR-012: Multi-Layer Test Coverage for Encryption
+**Date**: 2026-02-20
+**Status**: Accepted
+
+**Context**: Encryption parameters (cipher, keysize, format) defined in multiple files
+needed comprehensive validation to catch inconsistencies.
+
+**Decision**: Create tests at three levels: source files, implementation files, and documentation.
+
+**Rationale**:
+- Tests at each layer catch different types of errors
+- Preseed.cfg tests verify installer configuration
+- encryption-setup.sh tests verify runtime configuration
+- Documentation tests ensure user-facing accuracy
+- Integration tests verify consistency across files
+
+**Consequences**:
+- 16 additional tests to maintain
+- Changes to encryption params must update multiple test files
+- High confidence in encryption configuration correctness
+
+#### ADR-013: Single Username Convention
+**Date**: 2026-02-20
+**Status**: Accepted
+
+**Context**: Codebase had inconsistent username references (football vs kneluser),
+causing potential runtime failures in hooks.
+
+**Decision**: Standardize on 'football' as the primary user account name.
+
+**Rationale**:
+- Consistent with PRD specification
+- Reduces cognitive load for maintainers
+- Eliminates potential for hooks targeting wrong user
+- 'football' is the project name, easy to remember
+
+**Consequences**:
+- All hooks and scripts use 'football' consistently
+- If username needs to change, single grep/replace
+
+### Lessons Learned
+
+1. **Debian Installer Limitations**
+   - partman-crypto has limited preseed options
+   - Not all LUKS2 features are configurable during install
+   - Workaround: post-install configuration for advanced options
+
+2. **Test Coverage Layers**
+   - Testing source files alone isn't enough
+   - Test implementation files AND documentation
+   - Integration tests catch cross-file inconsistencies
+
+3. **Username Consistency**
+   - Simple string mismatches can cause runtime failures
+   - Grep entire codebase before standardizing names
+   - Add to coding standards for future reference
+
+### Commits
+
+```
+589c148 fix: standardize username to 'football' in all hooks (FINDING-008)

+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (from that copyright
+holder, and you cure the violation prior to 30 days after your receipt
+of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate
+you to collect a royalty for further conveying from those to whom you
+convey the Program, the only way you could satisfy both those terms and
+this License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    KNEL-Football Secure OS - Customized Debian ISO builder
+    Copyright (C) 2026 Known Element Enterprises LLC
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, version 3 of the License.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.

+### Step 3: Validate on Real Hardware
+- Install the ISO
+- Run `cryptsetup luksDump /dev/sda3` — verify KDF shows argon2id
+- Try `ssh localhost` — should be refused (no server)
+- Insert USB — verify mount has noexec,nosuid,nodev
+- Check `grep StrictHostKeyChecking /etc/ssh/ssh_config` — should be "yes"

-### FR-011: Host System Full Disk Encryption (MANDATORY)
+### FR-011: Secure Boot with Unified Kernel Image (UKI) (MANDATORY)
 
 **Priority:** P0 (Critical)
 **Status:** Required
 
 **Description:**
-The host system used to build or test KNEL-Football ISO images MUST have full disk encryption enabled. Building a secure operating system on an unencrypted host defeats the entire security model and creates a supply chain risk.
+The system MUST implement UEFI Secure Boot with a Unified Kernel Image (UKI) to ensure boot integrity and prevent unauthorized code execution during the boot process. This creates a complete chain of trust from firmware to the running operating system.
 
 **Requirements:**
-1. **LUKS Encryption Required** - Host must use LUKS for disk encryption
-2. **Build Enforcement** - `./run.sh iso` command MUST fail if host FDE not detected
-3. **VM Test Enforcement** - `./run.sh test:iso` commands MUST fail if host FDE not detected
-4. **No Bypass** - This check cannot be disabled or bypassed
-5. **Clear Error Message** - Users receive clear guidance on how to enable FDE
+1. **UEFI Boot** - System MUST boot in UEFI mode (no legacy BIOS)
+2. **Secure Boot Keys** - Custom PK, KEK, and db keys for signing
+3. **Unified Kernel Image** - Kernel, initramfs, and cmdline bundled into single signed EFI binary
+4. **Kernel Lockdown** - Kernel must be in lockdown mode when Secure Boot is active
+5. **Signature Verification** - All boot components must be cryptographically signed
 
-**Detection Methods:**
-- Check for LUKS devices via `lsblk -o TYPE,FSTYPE`
-- Check `/etc/crypttab` for configured encrypted partitions
-- Check if root filesystem is on a dm-crypt device
-- Check for dm-crypt devices in `/sys/block/dm-*`

-**Rationale:**
-- An unencrypted build host could be compromised, affecting all built ISOs
-- An unencrypted test host exposes the secure OS to attacks during testing
-- Supply chain security requires securing the entire build pipeline
-- Defense in depth requires protection at every layer
+**UKI Components:**
+1. **EFI Stub** - linuxx64.efi.stub for UEFI boot
+2. **os-release** - Operating system identification
+3. **cmdline** - Kernel command line with security parameters:
+   - `lockdown=confidentiality` - Kernel lockdown mode
+   - `module.sig_enforce=1` - Require signed kernel modules
+4. **linux** - Kernel image (vmlinuz)
+5. **initrd** - Initial ramdisk (initramfs)
 
-**User Guidance (if FDE not detected):**
-1. Backup all data
-2. Reinstall with "Guided - use entire disk and set up encrypted LVM"
-3. Or use tools like encrypt-existing-debian for in-place encryption
+**Key Specifications:**
+- **Algorithm**: RSA-4096
+- **Hash**: SHA-256
+- **Validity**: 3650 days (10 years)
+- **Format**: X.509 certificates, ESL (EFI Signature List)

+## File Editing Standards
+
+### Linux Command-Line Tools (MANDATORY for AI Agents)
+
+**AI agents MUST use standard Linux command-line tools for file editing, not internal text editing functions.**
+
+**Rationale:** Internal editing tools frequently fail due to:
+- Whitespace encoding mismatches (tabs vs spaces)
+- Line ending differences (CRLF vs LF)
+- Unicode/encoding issues
+- Exact text matching requirements that are brittle
+
+**Approved Tools:**
+| Tool | Use Case |
+|------|----------|
+| `sed` | Search/replace, line insertions/deletions |
+| `awk` | Field extraction, conditional processing |
+| `grep` | Pattern matching, filtering |
+| `patch` | Apply diff/patch files |
+| `cut` | Column extraction |
+| `tr` | Character translation |
+| `head`/`tail` | Preview file sections |
+| `sort`/`uniq` | Sort and deduplicate |
+
+**Standard Patterns:**
+
+```bash
+# In-place text replacement
+sed -i 's/old_text/new_text/g' file.txt
+
+# Replace on specific line number
+sed -i '42s/old/new/' file.txt
+
+# Insert line after match
+sed -i '/pattern/a\new_line' file.txt
+
+# Delete matching lines  
+sed -i '/pattern/d' file.txt
+
+# Multi-line replacement with extended regex
+sed -i -E 's/pattern/replacement/g' file.txt
+
+# Extract specific field (whitespace-delimited)
+awk '{print $2}' file.txt
+
+# Conditional processing
+awk '/pattern/ {print $1}' file.txt
+
+# Preview changes BEFORE applying (no -i flag)
+sed 's/old/new/g' file.txt | head -20
+```
+
+**Verification Workflow:**
+1. Read file: `cat file.txt` or `head -n 50 file.txt`
+2. Preview change: `sed 's/old/new/g' file.txt` (no `-i`)
+3. Apply change: `sed -i 's/old/new/g' file.txt`
+4. Verify result: `git diff file.txt`

+# KNEL-Football Secure OS - Executive Summary
+
+**Audit Date**: 2026-02-20
+**Auditor**: External Security Auditor
+**Classification**: CONFIDENTIAL
+
+---
+
+## Project Overview
+
+KNEL-Football is a hardened Debian 13 Linux distribution designed as a **secure remote terminal** for accessing tier0 infrastructure via WireGuard VPN. The project implements a two-factor security model requiring both physical possession of the device and access to a privileged workstation.
+
+---
+
+## Audit Scope
+
+- Security architecture review
+- Encryption configuration validation
+- Build system and supply chain analysis
+- SDLC compliance verification
+- Code quality assessment
+- Firewall and network security review
+
+---
+
+## Risk Assessment
+
+### Overall Risk Level: **MEDIUM**
+
+| Severity | Count | Key Areas |
+|----------|-------|-----------|
+| Critical | 0 | - |
+| High | 1 | Secure Boot keys |
+| Medium | 4 | Docker privileged, USB automount, KDF config, Supply chain |
+| Low | 3 | Test gaps, Documentation, Input validation |
+| Info | 2 | Firewall (by design), Package management |
+
+---
+
+## Critical Findings Requiring Immediate Attention
+
+### 1. Secure Boot Key Management (HIGH)
+Keys generated at build time without HSM or secure storage. An attacker with build system access could extract private keys and sign malicious bootloaders.
+
+**Impact**: Complete chain of trust compromise
+**Effort**: Medium (requires key management infrastructure)
+
+---
+
+## Design Decisions Confirmed
+
+### Firewall Output Policy (By Design)
+The strict OUTPUT DROP policy was confirmed as **intentional** for an immutable system:
+- Zero traffic leakage (no DNS poisoning, NTP spoofing, C2 exfiltration vectors)
+- Immutable system with no in-place updates (CVEs handled by ISO regeneration)
+- WireGuard endpoint loaded via USB disk (wg0.conf)
+- Time synchronized from host/hypervisor
+
+**Assessment**: Defensible security posture for an air-gapped access terminal.
+
+## Positive Security Observations
+
+1. **Strong SDLC Enforcement** - Pre-commit hooks enforce TDD, linting, and coverage
+2. **Comprehensive Encryption** - LUKS2 with AES-256-XTS-512, passphrase validation
+3. **Defense in Depth** - Multiple layers: FDE, firewall, audit, FIM, hardening
+4. **No SSH Server** - Correctly implements client-only SSH per requirements
+5. **Clean Code Quality** - All scripts pass shellcheck with zero warnings
+6. **Guest FDE (LUKS2)** - ISO images configured with LUKS2 + Argon2id encryption
+
+---
+
+## Recommendations Priority
+
+### Must Fix Before Release
+1. Disable USB automount (conflicts with security model)
+2. Verify Argon2id KDF is actually used in LUKS
+
+### Short-term (30 days)
+1. Implement Secure Boot key management with HSM or air-gapped storage
+2. Pin Docker package versions for reproducible builds
+3. Add functional integration tests for encryption
+
+### Long-term (90 days)
+1. Implement SLSA/SBOM for supply chain security
+2. Add USB authorization with usbguard
+3. Build environment attestation
+
+---
+
+## Compliance Status
+
+| Standard | Status | Notes |
+|----------|--------|-------|
+| NIST SP 800-53 SC-8 | ✅ Pass | WireGuard encryption |
+| NIST SP 800-53 SC-12 | ⚠️ Issue | Key management needs work |
+| NIST SP 800-53 AC-19 | ⚠️ Issue | USB automount |
+| NIST SP 800-111 | ✅ Pass | LUKS2 encryption |
+| CIS Benchmark 6.x | ✅ Pass | Comprehensive audit logging |
+| FedRAMP SC-7 | ✅ Pass | Strict output policy (by design) |

+# KNEL-Football Secure OS - Security Audit Report
+
+**Date**: 2026-02-20
+**Auditor**: External Security Auditor
+**Scope**: Comprehensive security and QA review
+**Classification**: CONFIDENTIAL
+
+---
+
+## Executive Summary
+
+**Overall Assessment**: The KNEL-Football Secure OS project demonstrates a **mature security posture** with strong architectural foundations. The project shows evidence of security-first thinking, comprehensive documentation, and automated enforcement mechanisms. However, several areas require attention before production deployment.
+
+### Risk Summary
+
+| Severity | Count | Areas |
+|----------|-------|-------|
+| **Critical** | 0 | - |
+| **High** | 2 | Secure Boot key management, Firewall output policy |
+| **Medium** | 4 | Docker privileged mode, USB automount, Argon2 KDF config, Supply chain |
+| **Low** | 3 | Test coverage gaps, Hadolint warnings, Documentation sync |
+| **Informational** | 5 | Various observations |
+
+### Key Strengths
+
+1. **Strong SDLC Enforcement**: Pre-commit hooks enforce TDD, linting, and test coverage
+2. **Comprehensive Encryption**: LUKS2 with AES-256-XTS-512, proper passphrase validation
+3. **Defense in Depth**: Multiple security layers (FDE, firewall, audit, FIM, hardening)

+5. **Clean Shellcheck**: All scripts pass shellcheck with zero warnings
+6. **Guest FDE (LUKS2)**: ISO images configured with LUKS2 + Argon2id encryption
+
+### Areas Requiring Attention
+
+1. **Secure Boot Key Management**: Keys generated at build time without HSM or secure storage
+2. **USB Automount**: Security risk for a secure workstation
+3. **Supply Chain**: No SLSA/SBOM, unpinned Docker packages
+
+**Note**: The strict firewall OUTPUT policy (FINDING-002) was confirmed as **intentional design** for an immutable system with zero traffic leakage.
+
+---
+
+## Detailed Findings
+
+### FINDING-001: Secure Boot Key Management (HIGH)
+
+**Category**: Cryptographic Key Management
+**Severity**: HIGH
+**Status**: Open
+
+**Description**:
+Secure Boot keys (PK, KEK, db) are generated at ISO build time using OpenSSL with self-signed certificates. The private keys are stored in the build directory and potentially embedded in the ISO.
+
+**Location**:
+- `run.sh:441-484` - `sb_generate_keys()` function
+- `run.sh:455-472` - OpenSSL key generation commands
+
+**Code Examined**:
+```bash
+openssl req -new -x509 -newkey rsa:4096 -sha256 -days 3650 \
+    -nodes -subj "/CN=KNEL-Football PK/" \
+    -keyout "${SB_KEY_DIR}/PK.key" \
+    -out "${SB_KEY_DIR}/PK.crt" 2>/dev/null
+```
+
+**Issues**:
+1. Keys generated on every build with no persistence or secure storage
+2. Private keys could be exposed in build artifacts
+3. No Hardware Security Module (HSM) integration
+4. 10-year validity without rotation policy
+5. No key escrow or recovery mechanism
+6. Subject DN uses generic CN without organization identification
+
+**Risk**: An attacker with build system access could extract private keys and sign malicious bootloaders.
+
+**Recommendation**:
+1. Pre-generate keys offline and store in HSM or air-gapped secure storage
+2. Only embed public keys/certificates in the ISO
+3. Implement key rotation policy
+4. Add key provenance documentation
+5. Consider using a commercial PKI for production deployments
+
+**Compliance Impact**: NIST SP 800-57, FedRAMP SC-12
+
+---
+
+### FINDING-002: Firewall Output Chain Default DROP (INFORMATIONAL - BY DESIGN)
+
+**Category**: Network Security
+**Severity**: INFORMATIONAL
+**Status**: By Design - No Action Required
+
+**Description**:
+The nftables firewall configuration sets a default DROP policy on the OUTPUT chain, only allowing loopback, WireGuard traffic, and ICMP ping.
+
+**Location**:
+- `src/firewall-setup.sh:43-47` - Output chain rules
+- `config/hooks/live/firewall-setup.sh:29-34` - Live hook output rules
+
+**Code Examined**:
+```bash
+chain output {
+    type filter hook output priority 0; policy drop
+    oif lo accept comment "Accept loopback"
+    udp dport "$port" ip daddr "$ip" accept comment "Allow WireGuard traffic"
+    icmp type echo-request accept comment "Allow ping"
+}
+```
+
+**Clarification from Project Team**:
+This is an **intentional design choice** for an immutable system security model:
+
+1. **Zero Traffic Leakage**: No DNS, no NTP, no HTTP/HTTPS - eliminates DNS poisoning, NTP spoofing, and C2 exfiltration vectors
+2. **Immutable System**: Package management disabled, no in-place updates - CVEs handled by regenerating ISO and recreating VM
+3. **WireGuard via USB**: Endpoint IP loaded from `wg0.conf` on USB disk at provisioning time
+4. **Time from Host**: VM receives time from hypervisor/host system, no network time sync needed
+5. **Known Endpoints**: WireGuard peer IP is static and pre-configured
+
+**Assessment**:
+This is a **defensible security posture** for an air-gapped, immutable access terminal. The strict OUTPUT DROP policy prevents:
+- Data exfiltration via DNS tunneling
+- C2 beacon traffic
+- Supply chain attacks via compromised update servers
+- NTP-based attacks
+
+**Recommendation**:
+Document this design decision in the security model documentation for future auditors.
+
+**Compliance Impact**: NIST SP 800-41, CIS Benchmark 3.x - Compensating controls in place (immutable system, no package management)
+
+---
+
+### FINDING-003: Docker Privileged Mode (MEDIUM)
+
+**Category**: Build Security
+**Severity**: MEDIUM
+**Status**: Open
+
+**Description**:
+The ISO build process runs Docker with `--privileged` flag.
+
+**Location**:
+- `run.sh:979` - Docker run command
+
+**Code Examined**:
+```bash
+docker run --rm --privileged \
+    -v "${SCRIPT_DIR}:/workspace:ro" \
+    ...
+```
+
+**Issues**:
+1. Privileged containers have full access to host devices
+2. Could allow container escape if build process compromised
+3. live-build requires privileged mode for loop device access
+
+**Risk**: If the build environment is compromised, attacker could escape to host.
+
+**Mitigating Factors**:
+1. Build runs in isolated environment (documented requirement)
+2. Build artifacts are read-only mounted
+3. Pre-commit hooks validate code before build
+
+**Recommendation**:
+1. Document the security implications of privileged mode
+2. Consider using rootless Docker or podman
+3. Implement build environment attestation
+4. Consider using dedicated build infrastructure
+
+---
+
+### FINDING-004: USB Automount Enabled (MEDIUM)
+
+**Category**: Endpoint Security
+**Severity**: MEDIUM
+**Status**: Open
+
+**Description**:
+The system automatically mounts USB storage devices when connected.
+
+**Location**:
+- `config/hooks/live/usb-automount.sh` - Entire file
+
+**Code Examined**:
+```bash
+cat >/etc/udev/rules.d/99-usb-automount.rules <<'EOF'
+ACTION=="add", SUBSYSTEM=="block", ENV{ID_FS_USAGE}=="filesystem", RUN+="/usr/local/bin/usb-automount.sh %k"
+```
+
+**Issues**:
+1. Automatic mounting of untrusted media is a security risk
+2. BadUSB attacks could compromise the system
+3. USB devices could exfiltrate data
+4. Conflicts with "secure workstation" threat model
+
+**Risk**: Physical access attack vector via malicious USB devices.
+
+**Recommendation**:
+1. Disable USB automount by default
+2. Implement USB device authorization (usbguard)
+3. Consider blocking USB storage entirely for tier0 access
+4. If USB required, implement manual mount-only policy
+
+**Compliance Impact**: CIS Benchmark 1.1.x, NIST SP 800-53 AC-19
+
+---
+
+### FINDING-005: Argon2id KDF Not Explicitly Configured (MEDIUM)
+
+**Category**: Encryption
+**Severity**: MEDIUM
+**Status**: Open
+
+**Description**:
+The PRD specifies Argon2id KDF for LUKS2, but the preseed.cfg does not explicitly configure it.
+
+**Location**:
+- `config/includes.installer/preseed.cfg:111-116` - LUKS configuration
+- `docs/PRD.md` - FR-001 requirement
+
+**Code Examined**:
+```bash
+d-i partman-crypto/cipher aes-xts-plain64
+d-i partman-crypto/keysize 512
+d-i partman-crypto/use-luks2 boolean true
+```
+
+**Issues**:
+1. No explicit Argon2id configuration in preseed
+2. Debian partman-crypto defaults may use PBKDF2
+3. Documentation claims Argon2id but implementation unclear
+
+**Risk**: If PBKDF2 is used instead of Argon2id, weaker key derivation against brute-force.
+
+**Recommendation**:
+1. Add explicit `d-i partman-crypto/keyscript` or post-install hook to enforce Argon2id
+2. Verify actual KDF in use after installation
+3. Add test to validate LUKS header uses Argon2id
+
+**Verification Required**: Install system and run `cryptsetup luksDump` to verify KDF.
+
+---
+
+### FINDING-006: Unpinned Docker Packages (MEDIUM)
+
+**Category**: Supply Chain
+**Severity**: MEDIUM
+**Status**: Open
+
+**Description**:
+Dockerfile does not pin package versions, using `apt-get install <package>` instead of `<package>=<version>`.
+
+**Location**:
+- `Dockerfile:16, 29, 45, 55` - apt-get install commands
+
+**Hadolint Output**:
+```
+-:16 DL3008 warning: Pin versions in apt get install
+-:29 DL3008 warning: Pin versions in apt get install
+-:45 DL3008 warning: Pin versions in apt get install
+-:55 DL3008 warning: Pin versions in apt get install
+```
+
+**Issues**:
+1. Non-reproducible builds - different package versions on different days
+2. Cannot verify exact software supply chain
+3. Security updates may introduce regressions
+
+**Recommendation**:
+1. Pin all package versions in Dockerfile
+2. Generate SBOM (Software Bill of Materials) during build
+3. Consider SLSA compliance for supply chain security
+4. Document package version freeze policy
+
+---
+
+### FINDING-007: Test Coverage Gaps (LOW)
+
+**Category**: Quality Assurance
+**Severity**: LOW
+**Status**: Open
+
+**Description**:
+Test coverage documentation claims 562 tests, but several areas have minimal testing.
+
+**Location**:
+- `tests/unit/encryption-validation_test.bats` - Only 4 tests
+- Various unit tests are text-based (grep for strings) not functional
+
+**Issues**:
+1. encryption-validation_test.bats has only 4 tests
+2. Many tests verify text presence rather than behavior
+3. No integration tests for actual LUKS encryption
+4. Firewall tests mock rather than execute nft
+
+**Examples**:
+```bash
+# Weak test - only checks for string presence
+@test "Validation checks for LUKS2 format" {
+    grep -q "LUKS\|luks" /workspace/config/hooks/installed/encryption-validation.sh
+}
+```
+
+**Recommendation**:
+1. Increase functional test coverage
+2. Add integration tests with actual cryptsetup operations
+3. Test firewall rules with nft --check
+4. Document test coverage gaps
+
+---
+
+### FINDING-008: Documentation-Code Synchronization (LOW)
+
+**Category**: Documentation
+**Severity**: LOW
+**Status**: Open
+
+**Description**:
+Some discrepancies between documentation and implementation.
+
+**Issues**:
+1. PRD specifies Argon2id, preseed doesn't configure it explicitly
+2. PRD FR-005 says WiFi/Bluetooth "permanently disabled", but modules can be reloaded by root
+3. User account inconsistency: preseed creates "football" user, hooks reference "kneluser"
+
+**Location**:
+- `config/includes.installer/preseed.cfg:38` - User "football"
+- `config/hooks/installed/encryption-validation.sh:106` - Path "/home/kneluser"
+
+**Recommendation**:
+1. Add documentation validation to CI
+2. Create user account consistency test
+3. Document the difference between "disabled" and "blacklisted" modules
+
+---
+
+### FINDING-009: QR Code Scanner Command Injection Risk (LOW)
+
+**Category**: Input Validation
+**Severity**: LOW
+**Status**: Open
+
+**Description**:
+The QR code import script parses untrusted input from QR codes and processes it with Python.
+
+**Location**:
+- `config/hooks/live/qr-code-import.sh:48-76` - Python QR parsing
+
+**Issues**:
+1. QR data is untrusted input
+2. Python script does minimal validation
+3. Could potentially inject malicious config values
+
+**Mitigating Factors**:
+1. Script runs as user (pkexec for elevation)
+2. WireGuard config has limited attack surface
+3. Physical access required to present QR code
+
+**Recommendation**:
+1. Add strict input validation in Python script
+2. Sanitize all parsed values before writing config
+3. Add length limits on QR data
+4. Log all QR imports for audit trail

+### FINDING-010: Package Management Disabled Aggressively (INFORMATIONAL)
+
+**Category**: System Administration
+**Severity**: INFORMATIONAL
+**Status**: Informational
+
+**Description**:
+Package management is disabled by removing execute permissions and making directories immutable.
+
+**Location**:
+- `config/hooks/installed/disable-package-management.sh`
+
+**Code Examined**:
+```bash
+chmod -x /usr/bin/apt /usr/bin/apt-get /usr/bin/dpkg
+chattr +i /usr/bin/apt /usr/bin/apt-get /usr/bin/dpkg
+rm -rf /var/lib/apt/* /var/lib/dpkg/*
+```
+
+**Observations**:
+1. Effective at preventing package installation
+2. Makes security updates impossible without recovery
+3. Consider document update procedure for security patches
+
+**Recommendation**: Document the security patching procedure for deployed systems.
+
+---
+
+## Positive Observations
+
+### OBSERVATION-001: Strong Pre-Commit Enforcement
+The pre-commit hook enforces SDLC requirements including linting, testing, and coverage checks. This is excellent security practice.
+
+### OBSERVATION-002: No Hardcoded Credentials
+No hardcoded passwords, API keys, or secrets found in the codebase. Password prompts are forced during installation.
+
+### OBSERVATION-003: Comprehensive Audit Rules
+The auditd configuration is thorough and covers security-critical files and operations.
+
+### OBSERVATION-004: SSH Client Only
+Correctly implements client-only SSH (no sshd installed) per PRD FR-006.
+
+### OBSERVATION-005: Guest FDE (LUKS2 + Argon2id)
+ISO images configured with LUKS2 encryption and Argon2id KDF for guest disk encryption.
+

+
+## Compliance Matrix
+
+| Standard | Requirement | Status |
+|----------|-------------|--------|
+| NIST SP 800-53 SC-8 | Transmission Confidentiality | ✅ WireGuard |
+| NIST SP 800-53 SC-12 | Cryptographic Key Management | ⚠️ See FINDING-001 |
+| NIST SP 800-53 AC-19 | Access Control for Mobile Devices | ⚠️ See FINDING-004 |
+| NIST SP 800-111 | Storage Encryption | ✅ LUKS2 |

+| CIS Benchmark 6.x | Logging and Auditing | ✅ Comprehensive audit |
+| FedRAMP SC-7 | Boundary Protection | ⚠️ See FINDING-002 |
+
+---
+
+## Recommendations Summary
+
+### Immediate (Before Release)
+1. Review and fix firewall OUTPUT chain policy (FINDING-002)
+2. Decide on USB automount policy (FINDING-004)
+3. Verify Argon2id KDF is actually used (FINDING-005)
+
+### Short-term (30 days)
+1. Implement Secure Boot key management plan (FINDING-001)
+2. Pin Docker package versions (FINDING-006)
+3. Add functional integration tests (FINDING-007)
+
+### Long-term (90 days)
+1. Consider SLSA/SBOM implementation
+2. Implement USB authorization (usbguard)
+3. Add build environment attestation
+
+---
+
+## Conclusion
+
+The KNEL-Football Secure OS project demonstrates strong security fundamentals with comprehensive encryption, hardening, and audit capabilities. The SDLC enforcement through pre-commit hooks is exemplary.
+
+The primary concerns relate to:
+1. Secure Boot key management (keys generated at build time)
+2. Firewall configuration that may break essential services
+3. USB automount conflicting with the security model
+
+With the recommended fixes, this project would be suitable for tier0 infrastructure access in compliance-focused environments.

+##### Secure Boot Keys
+
+| Key | Purpose | Algorithm | Validity |
+|-----|---------|-----------|----------|
+| PK (Platform Key) | Authorizes KEK updates | RSA-4096, SHA-256 | 3650 days |
+| KEK (Key Exchange Key) | Authorizes db updates | RSA-4096, SHA-256 | 3650 days |
+| db (Signature Database) | Signs EFI binaries | RSA-4096, SHA-256 | 3650 days |
+
+##### UKI Components
+
+| Section | Content | Purpose |
+|---------|---------|---------|
+| .osrel | /etc/os-release | OS identification |
+| .cmdline | Kernel parameters | lockdown=confidentiality, module.sig_enforce=1 |
+| .linux | vmlinuz-{version} | Kernel image |
+| .initrd | initrd.img-{version} | Initial ramdisk |
+
+##### Kernel Lockdown Effects
+
+When Secure Boot is active and kernel lockdown is enabled:
+- **No unsigned kernel modules** - module.sig_enforce=1
+- **No /dev/mem or /dev/kmem access** - Prevents direct memory manipulation
+- **No kexec** - Cannot replace running kernel
+- **No hibernation to untrusted storage** - Prevents data extraction
+- **No iopl/ioperm** - Restricts I/O port access
+- **No MSRs from userspace** - Restricts model-specific register access
+
+##### Secure Boot Enforcement
+
+- **Build Time**: Keys generated, UKI signed during ISO build
+- **Install Time**: Keys enrolled in UEFI firmware (setup mode)
+- **Boot Time**: UEFI verifies UKI signature before boot
+- **Runtime**: Kernel enforces lockdown mode restrictions
+
 #### 2. Network Security Layer
 
 - **Network Isolation** - No general internet access
