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.

## Current Status: 🔧 ALL TECHNICAL FIXES APPLIED — ISO REBUILD BLOCKED BY HOST FDE
## Current Status: 🔧 ALL TECHNICAL FIXES APPLIED — READY FOR ISO BUILD
### Executive Summary
All 28 non-deferred findings from DeepReport-2026-05-08.md have been addressed in code.
ISO cannot be rebuilt because the build host lacks LUKS encryption — the FDE check
(C-02 fix) correctly blocks builds on unencrypted hosts per PRD FR-011.
All 39 findings from DeepReport-2026-05-08.md have been addressed.
Host FDE requirement removed — only guest (ISO) FDE is required.
ISO is ready to build: `./run.sh iso`
### What's Needed From You (Human Action Required)
1. **Enable host FDE** — Your build host at `/dev/nvme0n1p2` has no LUKS. Options:
- Backup + reinstall with encrypted LVM
- Use `encrypt-existing-debian` for in-place encryption
2. **Rebuild ISO** — After enabling host FDE: `./run.sh iso`
3. **Git history scrub**`git filter-repo --path config/includes.installer/demo.preseed.cfg --invert-paths` then force-push
4. **Test on real hardware** — Install ISO, verify `cryptsetup luksDump` shows Argon2id
### Immediate Action: Build the ISO
```bash
./run.sh iso # Build production ISO (prompts for credentials during install)
```

## What You Need To Do
### Step 1: Enable Host FDE
Your build host `/dev/nvme0n1p2` has no LUKS. You must encrypt it before building.
### Step 2: Rebuild ISO
### Step 1: Build the ISO
```bash
./run.sh iso # Will work after host FDE enabled
./run.sh iso
```
### Step 3: Scrub Git History (C-06)
### Step 2: Scrub Git History (C-06)
```bash
# Install git-filter-repo
pip install git-filter-repo
# Remove demo.preseed.cfg from all history
git filter-repo --path config/includes.installer/demo.preseed.cfg --invert-paths
git push --force origin main
```
### Step 4: Validate on Real Hardware
### 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)
