Restructure top-level to exactly three .md files:
- AGENTS.md (agent operating instructions)
- README.md (project overview, links to status + docmap)
- STATUS.md (living project status, agent-maintained, human read-only)
Add docs/docmap.md as the single documentation index/map. All docs are
categorized (active, operational guides, historical) with last-reviewed
dates. Includes the agent gardening protocol requiring agents to update
STATUS.md and docmap.md after every work session.
Rewrite AGENTS.md to be lean: points to docmap.md for doc discovery,
encodes the automatic gardening protocol (keep docs/code in sync, grep
for stale paths after renames, update STATUS.md after infrastructure
changes). All references are Gitea-renderable relative links.
Simplify README.md: header links to STATUS.md + docmap.md + AGENTS.md,
doc table replaced with pointer to docmap.md.

Comprehensive documentation gardening across the merged repo:
- tailscale.md: fully rewritten with current ground truth. The netinfra
pair now runs production Technitium with all knel.net records
replicated. Both LAN IPs resolve knel.net device names and recurse
externally. The old "NXDOMAIN / zone is stale" findings are replaced
with the resolved state and current recommendations.
- AGENTS.md: rewritten with Gitea-compatible clickable relative links
to all key scripts and docs. Autonomous commit/push policy
prominently documented. SSH user corrected to localuser.
- README.md: directory table and docs table now use clickable links.
- All .md cross-references converted to Gitea-renderable relative links.
- Stale path references (ProjectCode/, Project-Tests/, ProjectDocs/)
updated to current names (provisioning/, tests/) across all docs.
- Stale repo name "FetchApply" / "KNELServerBuild" updated to
"PFVCluster" in actionable docs; historical AI-review docs tagged
with an HTML comment notice.
- REFACTORING-EXAMPLES.md: tagged as historical (pre-refactor patterns).
- tests/README.md, dns-cluster-setup/README.md, docs/DEPLOYMENT.md,
docs/SECURITY.md: path references fixed to current structure.

Set up a fully scripted, documented Technitium DNS cluster that
replicates the production instance from tailscale-router to
pfv-netinfra-01 (primary) and pfv-netinfra-02 (secondary).
What it does:
- EXPORT: reads the production Technitium config (auth.config with
users + 2FA, dns.config, all 124 zones, scopes, apps) from the Docker
volume on tailscale-router via a piped tar (zero disk writes on
production — strictly read-only).
- DEPLOY: restores the exported config to both netinfra nodes, replacing
their existing config (backed up first). Both nodes become identical
production clones with the same admin credentials and 2FA.
- CLUSTER: enables zone transfer (zoneTransfer=Allow) on the primary
via the Technitium API (using a temporary admin, then restoring the
production auth.config). Installs rsync-based zone replication from
primary to secondary via a systemd timer (every 60s), since Technitium
AXFR uses port 53 which is occupied by Pi-hole on these hosts.
- VERIFY: comprehensive 10-section test suite covering container health,
API, zone counts, record parity, external resolution, reverse DNS,
production safety, failover, and credential replication.
Scripts:
- remote-dns.sh: SSH chokepoint for all DNS host access
- setup.sh: master orchestrator (export → deploy → cluster → verify)
- sync-zones.sh: rsync-based zone replication (installed as systemd timer)
- verify.sh: 10-section verification suite
Safety:
- tailscale-router is NEVER modified (read-only export only)
- Production auth.config is backed up before any temporary admin swap
- Each node's existing config is backed up before replacement
- The export tarball is gitignored (contains production credentials)

The ntp.conf hardening used `interface ignore wildcard` +
`interface listen 127.0.0.1`, which binds ntpd to loopback only. Outbound
NTP queries to the upstream servers then carried a 127.0.0.1 source
address that the servers cannot reply to, so the daemon's peers stayed
stuck in .INIT. with reach 0 — even though the servers are reachable
(verified: ntpdate -q succeeds, ntpd does not).
Replace the interface-based restriction with restrict-based hardening:
`restrict default ignore` blocks unsolicited queries from any host (so
the box never serves time to others), while explicit allow rules for the
two upstream servers and localhost let the client sync normally.

Add an architecture analysis for the tension between Tailscale's
default resolv.conf management (100.100.100.100) and the managed
LAN-resolver resolv.conf (.252/.253). Documents a key finding from
live-network probing: knel.net device records only resolve via the
Tailscale MagicDNS path; querying the LAN DNS servers directly returns
NXDOMAIN because their knel.net zone is stale (SOA serial 2025-06-23).
Lays out four options (Tailscale-owned, LAN-pinned, split DNS,
Tailscale-pushes-LAN-resolvers) with pros/cons, recommends leaving DNS
to Tailscale in the short term (since wazuh/postfix/syslog depend on
knel.net names that only resolve there) and fixing the Technitium/Pi-hole
knel.net zone before pinning the LAN resolvers. Confirms the NTP
(LAN-IP) change is safe regardless. Flags that the managed-resolv.conf
change will be overwritten by Tailscale and would break knel.net
resolution if it ever sticks.

Route every host built by this project through the new
pfv-netinfra-01 (192.168.3.252) / pfv-netinfra-02 (192.168.3.253)
pair for both name resolution and time, with automatic failover.
- NTP: replace the single pfv-netboot.knel.net upstream with both
netinfra servers (iburst) so time sync survives either one failing.
- DNS: add a managed static /etc/resolv.conf (new ConfigFiles/Resolv/).
The repo previously had no resolver configuration at all. Both servers
are listed so glibc falls through to the secondary on failure.
- DHCP: request domain-name-servers/domain-search/ntp-servers and
supersede them to the netinfra pair, so a DHCP renew can't silently
revert to whatever the DHCP server advertises.
- SetupNewSystem.sh: deploy resolv.conf (robustly replacing any
systemd-resolved/NetworkManager symlink) and add pfv-netinfra to the
NTP-server self-exclusion guard so those boxes don't client off
themselves.
LAN IPs are used throughout (not the knel.net hostnames) because those
hostnames resolve to Tailscale CGNAT addresses, not the LAN addresses,
and NTP must come up before DNS. Add a validation test asserting the
config is present and both servers actually answer DNS and NTP queries.

Deployed check.sh to all 7 hosts at 21:50 CDT. Captures the live state
after the user's PDM migrations:
Cnode movements since last audit:
- cnode1: tsys1 -> tsys9
- cnode2: tsys6 -> tsys7
- cnode5: tsys6 -> tsys7, storage D5(tsys4) -> S2(tsys5)
Wnode changes:
- wnode-tsys1 (102): new VM on S2, stopped
- wnode-tsys3: RAM bumped 20 -> 28 GB
- wnode-tsys6: now running (was stopped)
- wnode-tsys9: storage moved S3 -> S2
Storage distribution improved from 90/10 to 73/27 (tsys4/tsys5).
Still need 2 more cnode moves for etcd quorum survival.
Updated executive summary, k8s distribution tables, storage
utilization, and open items with the fresh data. Captured future k8s
requirements: vcluster + Rancher, OIDC to Keycloak, workload isolation
(RackRental/Suborbital ITAR/non-ITAR/SLP), and solar-aware scale-out
with PowerEdge 19xx/2950 systems.
Added tsys9 to deploy-check.sh host list.
Storage philosophy (user directive):
- NVMe/SSD: k8s worker scratch + ultix-streaming (dev workstation
running "cluster of 1" pre-prod jobs before full k8s deployment)
- Spinning rust: all infrastructure VMs (UCS, netinfra, LibreNMS, SIEM)
Clarified that hosts are standalone but managed via Proxmox Datacenter
Manager (PDM), which supports VM migration between nodes through the
UI -- eliminating the need for manual disk copies in the migration plan.
Updated all migration steps to reference PDM storage migrate instead
of manual cp commands.

Three tests produced false failures when run on the deployed host:
- safe-download: the read-only-location assertion expects a write to
fail, but the suite runs as root and root bypasses filesystem
permissions, so the write succeeded. Skip that assertion as root.
- 2fa-validation: package presence used `dpkg -l | grep`, whose
fixed-width output wraps long names when COLUMNS is narrow (as in a
non-interactive shell), falsely reporting libpam-google-authenticator
and qrencode as missing even though they were installed. Use dpkg -s.

OCSP stapling that many valid CDNs do not provide, flagging valid
certificates as invalid. Drop it; --ssl-reqd still enforces TLS and

Three bugs prevented the validation suite from running cleanly:
- run-tests.sh used `((TESTS_PASSED++))` under `set -e`. Post-increment
evaluates to the old value, so the first passing test (0 -> 1) made
`(( ))` return 1 and errexit aborted the whole run after exactly one
test. Use plain arithmetic assignment instead.
- https-enforcement.sh's comment filter ran `grep -n` (which prefixes
"linenum:") and then tried to drop comment lines with
`^[[:space:]]*#`, which never matched the line-number prefix. Every
http:// URL in a comment (deprecated curl lines, the strict-mode
attribution comment) was flagged as a violation. Match the prefix.
- 2fa-validation.sh hardcoded `/home/$user/` for the setup-instructions
check, so for root it looked in /home/root (which does not exist)
instead of /root. Resolve the home directory with getent.

secharden-2fa enforces AuthenticationMethods publickey,keyboard-
interactive, so once setup completes no non-interactive SSH client can
authenticate (a TOTP token is required). The harness's post-deploy steps
— log fetch, repo path resolution, and the validation suite — all relied
on SSH and therefore failed after the first successful deploy, masking
the fact that setup itself had completed (rc=0).
- remote.sh: add a vm-guest mode that runs commands as root inside the
VM via the Proxmox qemu-guest-agent (qm guest exec), bypassing SSH/2FA
entirely. Output is parsed on the Proxmox host with python3.
- vm-validation.sh: resolve repo path, fetch the setup log, and run the
validation suite via vm-guest when SSH is unavailable. Detect the
setup exit marker from the always-available live stream as a fallback
to the fetched log. Make restore_vm_access 2FA-aware so a post-deploy
SSH failure is understood (not a hard error) once 2FA is in effect.

configure_ssh_2fa only enabled the deprecated ChallengeResponseAuthentication

keyboard-interactive). The base tsys-sshd-config ships
KbdInteractiveAuthentication no, so on Debian 13 (OpenSSH 9.x/10.x)

Without a trailing newline the append fused onto the last line,

secharden-wazuh.sh did a hard `systemctl start wazuh-agent`. The agent

The KexAlgorithms line in ssh-audit-hardening.conf began with a space.
In sshd_config a leading whitespace marks a line continuation, so the
entire directive was absorbed as arguments to the (non-existent)
previous directive. The effective kexalgorithms collapsed to only the
two trailing GSSAPI entries (gss-curve25519-sha256-, gss-group16-sha512-),
which no normal OpenSSH client can negotiate.
Result: after secharden-ssh deployed this file, every SSH connection to
the host died in [preauth] with no usable key exchange algorithm. sshd -t
still returned 0, so the breakage was completely silent.

repo path on the VM before sudo to avoid the '~' -> root's home trap.
