     hardened: fail-open guard now covers the transit-iface existence AND the WAN bridge/uplink enslavement.
   - Harness: `site-headend-install` 49->54; `wan-bridge` covered by opentofu-validate S3. Records: D-125,
     SEC-010, model-a-fallback B->A delta (item 8 + revert), platform-traps 1g.
+  - **D-125 COMMITTED `d34ec94` + PUSHED** (operator "commit", then "push"). Branch
+    `dc-dc-stage3-phase2-dc-substrate` now carries `114d392` (A+B) + `5175365` (C+D) + `d34ec94` (D-125)
+    on origin.
+
+- **Doc drift-reconciliation batch (post-Model-B/D-125), all doc-only, COMMITTED + PUSHED:**
+  - `8496c2e` -- `dc-dc-deployment-workflow.md` Stage-3 section reconciled to D-121..125 + Model B
+    two-root (Build/Gate/Owns/Authoring-status/rulings-summary); gap-register D-113(a2) OPEN->DONE.
+  - `87f9d75` -- `opentofu/README.md`: authoritative STATUS-RECONCILED banner (two roots, added
+    `site-wan`/`wan-bridge`, instantiation reality) + neutralized the DELETED, dangerous OPNsense
+    config.xml/config-ISO path (D-112/D-113(a2)).
+  - `788911c` -- `runbooks/dc-dc-teardown-rollback.md`: Model B two-root teardown banner (site-down =
+    one `virsh destroy vvr1-dc0`; inner-then-outer order; maas-vm-host targets inner virsh).
+  - Repo-wide drift scan confirmed the deleted-file / old-node-count references elsewhere are all
+    immutable CHANGELOGS, decision-record supersession context, or deliberate tombstones
+    (`opentofu/templates/README.md`) -- NOT live drift. Deeper prose in the three reconciled docs +
+    the Stage-4/5 sections still lag Model B (flagged in-banner as historical), not yet rewritten.
 - **Phase D NOT STARTED** -- SEC-010 rack `ip_forward=0` + firewall artifact + mechanical pre-apply gate.
 - **Phase E NOT STARTED** -- operator assigns rack transit/30 + rack IP in office1-netbox (apex token),
   fill tfvars -> `tofu plan` renders.
