docs(agent): queue #123–#124 + diagnose #95 from Acer/XPS install photos

Real installs on Acer Aspire M5-481T and Dell XPS 9350 (2026-07-14):

- #123: HM pre-activate dies at dconf without XDG_RUNTIME_DIR on both
  machines — partial first boot (weird GTK + missing nm-applet are
  symptoms of the incomplete bake).
- #124: install seeds ?ref=v1 while writing main-era nomarchy.hardware.*,
  and v1 lags hard enough that rebuilds die with "option does not exist".
- #95: Ghostty on the Acer is OpenGL 4.2 < required 4.3 (OpenGLOutdated);
  XPS starts Ghostty fine.

HARDWARE-QUEUE V3 rows; photos stay local (.gitignore WhatsApp Image*).

+## 2026-07-15 — File install findings from Acer + XPS photos (no code)
+- **Task:** Bernardo: real installs on Acer Aspire M5-481T + Dell XPS 9350;
+  photos of the install end screens and post-boot sessions. Figure out
+  issues and queue them — do not implement in this iteration.
+- **Did:** Read the six photos. Three distinct root causes (not one vague
+  "home didn't build"):
+  1. **#123** — HM pre-activate dies on both machines at dconf
+     (`/run/user/1001/dconf: Permission denied`) → partial first boot
+     (weird GTK + missing nm-applet are *symptoms*, not separate bugs).
+  2. **#124** — seeded flake hardcodes `?ref=v1` while installer writes
+     main-era `nomarchy.hardware.*`; v1 lags (~hundreds of commits) →
+     `nomarchy.hardware does not exist` on Acer rebuild/pull.
+  3. **#95** enriched — Ghostty on Acer is OpenGL 4.2 < required 4.3
+     (`error.OpenGLOutdated`); XPS starts Ghostty fine.
+  HARDWARE-QUEUE V3 rows for all three. Photos stay local (not committed).
+- **Verified:** V0 (docs/agent only).
+- **Pending:** implement #123 first (unblocks first-boot polish); then
+  #124; #95 is independent (old-GPU floor).
+- **Next suggestion:** #123 (installer bake) — highest blast radius.
+
 ## 2026-07-15 — #119: mime defaults must name a present .desktop (this commit)
 - **Task:** BACKLOG #119 — `text/plain` named vscode, which the live ISO never
   ships (same GIO-skip trap as #94, one key over).
