D-113(a2) COMPLETE: DELETE the config.xml path (template, renderer, ISO builder) ...

Operator ruling ("I'll defer to your lean"): the OPNsense config.xml template is DELETED, not
reduced.

WHY DELETED RATHER THAN REDUCED: the (a2) plan was to shrink the template to a minimal bootstrap
(sshd + root key + console + a seeded API key). That proved UNNECESSARY -- every one of those is
covered without a config.xml at all:

  sshd + root key            -> the D-112(c) console bootstrap (proven on Office1)
  an API key                 -> scripts/opnsense-bootstrap-apikey.sh (OPNsense's OWN model; no GUI
                                click, no re-implemented crypto)
  DHCP/firewall/interfaces   -> the REST API (proven read AND write)

So the provisioning chain has NO config.xml anywhere:
  boot factory nano -> console bootstrap -> mint API key -> configure over REST

A config.xml renderer that nobody should ever run is not a safety net -- it is a loaded gun
pointed at a live router. The 2026-07-13 safety sweep is the evidence: the repo still contained
runbook steps telling an operator to render a config and push it to the edge, which by then would
have CLOBBERED live API-managed DHCP.

DELETED: opentofu/templates/opnsense-config.xml.tmpl; scripts/opnsense-render-config.sh +
tests/opnsense-render-config/; scripts/opnsense-build-config-iso.sh +
tests/opnsense-build-config-iso/; the opnsense-edge module's config_seed volume + cdrom disk and
its config_iso_path variable; the xorriso/genisoimage prereq (it existed ONLY for the ISO
builder). Gauntlet 54 -> 52 harnesses (the two deleted scripts took their harnesses with them --
expected arithmetic, not a regression). All files remain in git history.
opentofu/templates/README.md is now a TOMBSTONE explaining what happened and what to use instead.

THE LIVE CHANGE IS NOT APPLIED IN THIS COMMIT. Removing the module's ISO wiring touches an
INSTANTIATED resource (libvirt_volume.config_seed is in tfstate). Measured with `tofu plan` first:

  module.office1_opnsense.libvirt_domain.vm will be updated IN-PLACE
  module.office1_opnsense.libvirt_volume.config_seed will be destroyed
  Plan: 0 to add, 1 to change, 1 to destroy.

NO replacement of the running domain -- confirmed explicitly. A replacement would have DESTROYED
the live, routing, DHCP-serving edge, and would have been grounds to stop.

A LINT GUARD DID ITS JOB: repo-lint's L3 (runbooks must not reference missing scripts) went RED on
the tombstone notes, because they named the deleted paths. The rule was RIGHT and it has no
opt-out (only L4 does). Rather than weaken a guard that exists to stop runbooks pointing at dead
scripts, the tombstones were reworded to name the bare filename instead of the scripts/ path. The
guard stays fully intact; the information is preserved.

Verification: repo-lint 0 fail; opentofu-validate PASS (root + 10/10 modules standalone);
gauntlet ALL GREEN (52).

Revert: git revert this commit (restores template/renderer/ISO builder/harnesses), then
`cd opentofu && tofu apply` to re-create the (inert) config_seed volume + cdrom.

DOCFIX-189: re-audit the max-context session's troubleshooting + docs ...

Operator-instructed re-evaluation. The 2026-07-12 session authored its docs and
module comments WHILE WORKING FROM A WRONG DIAGNOSIS, at a context limit, so its
reasoning was re-checked rather than just its one-line bug (DOCFIX-188).

Headline: the settings it changed are mostly fine and are RETAINED. The reasoning
it recorded was not -- it attributed the fault to whatever knob was being turned,
on no evidence, four separate times. It also left one silently-dead knob.

FALSE CAUSAL CLAIMS (corrected at the source, opnsense-edge/main.tf). The disk
shape, q35->i440fx, the serial console and svm-disable were EACH written up as a
contributing cause. None changed the symptom -- the fault sat at a deterministic
262 bytes through all of them. All four settings RETAINED (each defensible on its
own merits); only the false justifications are gone. The serial console earned its
keep, but it REVEALED the fault, it did not change it.

DEAD KNOB (real functional defect). `disk_size_bytes = 16 GiB` did nothing once
DOCFIX-187 made the disk a direct copy; unused variables are legal HCL so neither
validate nor plan complained. MEASURED: the live disk is 11.00 GiB, not 16.
Removed from main.tf + module variables; real sizing is opnsense-prep-image.sh's
GROW (+8G). Proof it was dead: tofu plan is byte-identical before/after removal.

STALE/UNSOURCED FACTS. "Opteron_G3" is a red herring -- the host is really an AMD
EPYC 9965 (Zen 5, family 26); libvirt's CPU-model DB doesn't know family 26 and
falls back to the oldest name, and the prior session partly built its nested-virt
theory on that artifact. "OPNsense's 3 GB min" is unsourced -- annotated, do not
propagate. DOCFIX-186's backing_store parenthetical is stale (same conclusion,
different mechanism). DOCFIX-187's changelog gains a SUPERSEDED-IN-PART header.

KEPT: DOCFIX-186's apparmor + config-iso-staging findings are real and measured.
DOCFIX-185 (operator transport ruling) untouched.

STANDING LESSON: when a change does not fix the symptom, do not write it up as
though it did. A fault that is deterministic and immune to every knob you turn
means you have not yet touched the cause.

Gauntlet ALL GREEN (52); repo-lint 0 fail; tofu fmt/validate/plan clean.

DC-DC Stage 1 (dc-dc-phase0): first real execution + scaffold/tooling fixes ...

First end-to-end run of a DC-DC runbook against real infrastructure (vcloud host,
OpenTofu v1.12.3). Applied 13 libvirt objects (6 DC1 planes, dc1/office1/dc2
pools, office1-local, 3 mesh legs, all MTU 9000); prior VR0 nets torn down (wan
kept as a gap-#17 model); DC2 planes deferred (NetBox supernet), DC2 storage wired.

DOCFIX-178: scripts/prereqs/ idempotent workstation prereq installers + a
  Prerequisites section in the runbook + tests/prereqs/ (25/25). Runbooks must
  not assume prereq runtimes.
DOCFIX-179: OpenTofu scaffold first validation + apply. Per-module
  required_providers (child modules do NOT inherit provider SOURCE -> OpenTofu
  inferred nonexistent hashicorp/libvirt); tofu fmt -recursive; provider "maas"
  deferred to Stage 3 (kept a sensitive key out of Stage-1 plan/state);
  repo-lint now skips the .terraform/ provider cache; .terraform.lock.hcl added.
DOCFIX-180: dc-dc-phase0 runbook as-executed corrections folded in at phase
  close (two MTU domains, non-pristine-host handling, Step-9 13-resource plan,
  -input=false, Known-Gap resolved).

repo-lint 0 fail; prereqs harness 25/25; repo-lint harness 34/34.

DOCFIX-148: OpenTofu module audit pass + provider-docs skill reference ...

Audited every "UNVERIFIED"/"inferred"/"assumed" marker across all 9 modules
built this session rather than leaving them as-is. Found and fixed a real
documentation error: opnsense-edge's comments claimed devices.interfaces
list order directly sets OPNsense's LAN/WAN role. Researching OPNsense's own
interface-assignment model showed this conflates two things -- list order
plausibly controls which vtnetN device number a NIC gets (libvirt's own
docs: auto-assigned PCI addresses "usually match" XML order for a simple
topology), but the actual LAN/WAN role is a separate, explicit mapping set
inside config.xml itself ("vtnet0=WAN" is a convention some guides choose,
not an enforced rule). Corrected main.tf's comments and both
lan_network_name/wan_network_name variable descriptions -- no config.xml
exists in this repo yet, so this fixes documentation accuracy for whoever
writes it next, not current behavior.

Confidence upgraded (not just re-hedged) on three other items: node-vm's
boot={order=N} shape (confirmed the provider 1:1-mirrors libvirt's own XML,
and libvirt's own docs confirm the single-attribute shape), create.content.url
accepting local paths (second independent source), and the genisoimage
flags (confirmed standard, cleanly separated from the still-open question of
whether OPNsense's Importer actually reads the result). Confirmed safe:
maas_vm_host's zone/pool computed-if-unset behavior.

Added .claude/skills/openstack-cloud-ops/references/opentofu-provider-docs.md:
indexes every provider/doc source used this session with exact URLs and
confirmed versions, plus the fetch methodology that actually worked
(Registry doc pages are JS-rendered, use GitHub instead; branch names vary,
check default_branch via the API; real example .tf files beat doc-summarized
prose for syntax questions). Wired into SKILL.md's routing table,
cross-referenced from opentofu/README.md in both directions without
duplicating content.

DOCFIX-146: opnsense-edge module + nano-image/config-ISO prep scripts ...

Implements the mechanism identified in today's OPNsense deployment research
(cloud-init confirmed unreliable on FreeBSD; the real native mechanism is
OPNsense's Configuration Importer, which scans an attached volume for
/conf/config.xml and gained ISO9660 support specifically for VM/cloud
automation).

scripts/opnsense-prep-image.sh: downloads the nano image, decompresses,
converts raw->qcow2, resizes -- work create.content.url almost certainly
can't do itself (a plain fetch, no decompression). No hardcoded mirror URL;
OPNSENSE_MIRROR_BASE is required explicitly.

scripts/opnsense-build-config-iso.sh: builds the ISO9660 image containing
/conf/config.xml that the Configuration Importer picks up.

opentofu/modules/opnsense-edge: wires both together, mechanically identical
to modules/cloudinit-vm's cdrom-attach shape but with no libvirt_cloudinit_disk
resource (wrong format for this). Explicit lan_network_name/wan_network_name
variables rather than an ordered list, since OPNsense's interface-1-is-LAN
convention makes list-ordering a real place for a silent mistake to hide. No
PXE boot-order attribute used -- this VM boots from its own disk, not the
network, so node-vm's flagged-unverified boot field doesn't apply here.

Both new scripts' harnesses (4/4, 3/3) exercise REAL missing-tool guards --
qemu-img/genisoimage/xorriso are all genuinely absent from this environment.
Two things flagged, not presented as fact: whether the Importer's ISO9660
behavior holds on a real boot, and whether interface list-order reliably
maps to LAN/WAN NIC enumeration for this guest. config_iso_path has no
default -- real config.xml content per site is still undesigned. Not
instantiated in root main.tf.
