docs(agent): promote V2-capable PROPOSED items to NEXT #51–54

Bernardo-directed triage (VM now free post-#46): #51 Waybar/menu
behaviour bugs, #52 theme fidelity Broken/high-ROI fixes, #53 missing
previews + neon-glass whole-swap, #54 installer safety + polish. Promoted
pitches removed from PROPOSED (breadcrumbs left); non-selected V2 items

+- **Waybar doctor indicator never shows an icon:** `modules/home/waybar.nix`
+  `nomarchy-doctor-status` prints `"text":""` on failure — empty-text custom
+  modules self-hide, so the tripwire never appears. Fix: non-empty glyph
+  (e.g. `󰒡`) + `class: bad` when unhealthy; no output/exit 0 when healthy.
+- **Control Center appearance toggles are silent no-ops:**
+  `nomarchy-control-center.sh` `set_state` is always `--no-switch`, so
+  blur/gaps only land on a later rebuild with no warning (unlike
+  Updates/Bluetooth). Fix: run a switch for appearance keys, or warn clearly.
+- **summer-day workspace scroll misaligned:** `themes/summer-day/waybar.jsonc`
+  uses `workspace e+1/e-1` (next empty) vs every other bar's `r±1` (relative)
+  — align to `r±1`.
+V2: theme-shot session render (and/or a `checks.doctor` extension for the
+indicator).

+
+### 53. Missing theme previews + neon-glass whole-swap (promoted 2026-07-09, V2)
+- Capture `executive-slate` + `neon-glass` `preview.png` headlessly via the
+  theme-shot recipe proven on boreal (480×270); optional hand `btop.theme`.
+- **First, for neon-glass:** its `waybar.css` uses `@text/@base/…` with no
+  `@define-color` block (and no `waybar.jsonc`), so applying it yields broken
+  bar colours. Decide: **finish** (self-contained colours + jsonc + preview)
+  or **quarantine** (remove `waybar.css` → falls back to the generated bar),
+  then capture the preview. V2 render.
+
+### 54. Installer safety + polish (promoted 2026-07-09, V0+V2)
+- **Offline fail-closed:** when the offline path is active and
+  `compose-lock.py` fails, the script currently *warns* and runs `nix flake
+  lock` (needs network) → a promised offline install can hang. Fail the
+  install with a clear message instead. (V2 offline install.)
+- **Destructive-data warning:** at disk selection/review, if `lsblk -f`/`blkid`
+  shows Windows/BitLocker/NTFS/existing-LUKS on the **chosen** disk, add one
+  explicit "data will be destroyed" line. Single whole-disk only — no
+  dual-boot path. (V0 + V2.)
+- **Password min length = 8:** the account password only requires non-empty
+  while LUKS needs ≥8 — align to one 8-char rule (not a strength meter). (V0.)
+- **HM pre-activate recovery hint:** on pre-activate failure, drop a flag
+  file / MOTD snippet on the target so first login still shows the fix
+  (observed warning this session; the install still booted themed). (V2.)

 ### Bugs / broken behavior (codebase exam 2026-07-09)
 
-- **Waybar doctor indicator never shows an icon**
-  `modules/home/waybar.nix` `nomarchy-doctor-status` prints
-  `"text":""` on failure. Waybar custom modules with empty `text`
-  self-hide, so the tripwire never becomes visible (tooltip-only if
-  it rendered at all). Intent in comments is opposite: appear only
-  when the sheet has a ✖. Fix: non-empty glyph (e.g. `󰒡` / `!`) +
-  `class: bad` when unhealthy; exit 0 / no output when healthy.
-  Cost: one-line script fix; V2 with existing `checks.doctor` if
-  extended, else V1.
-
-- **neon-glass theme ships a broken Waybar whole-swap**
-  `themes/neon-glass/waybar.css` uses `@text` / `@base` / `@accent` /
-  etc. with **no** `@define-color` block. Whole-swap CSS replaces the
-  entire stylesheet with no palette prepend (`waybar.nix`), so
-  applying neon-glass yields undefined / broken bar colors (same
-  class as the purged stub CSS, JOURNAL #45). Also missing
-  `waybar.jsonc`, `preview.png`, `btop.theme`; CSS covers only a
-  subset of modules. Fix: either finish (self-contained colors +
-  layout parity + preview) **or** remove `waybar.css` until ready so
-  apply falls back to the generated bar. Cost: medium polish or
-  small quarantine delete; V2/V3 visual.
-
-- **Control Center appearance toggles are no-ops without a rebuild**
-  `nomarchy-control-center.sh` `set_state` always uses `--no-switch`.
-  Blur / gaps (and similar appearance keys) only take effect after a
-  home switch, but the UI never runs one and never warns (unlike
-  Updates/Bluetooth which print "requires rebuild"). User flips look
-  identical until a later rebuild. Fix: run switch for appearance
-  keys, or refuse / warn clearly. Cost: small UX fix in one script.
-
-- **summer-day workspace scroll dispatches differently from every other bar**
-  `themes/summer-day/waybar.jsonc` uses `workspace e+1` / `e-1` (next
-  **empty** workspace); summer-night, executive-slate, boreal use
-  `r+1` / `r-1` (relative). Likely leftover; behavior differs under
-  scroll. Fix: align to `r±1`. Cost: two lines.

-- **Missing theme picker previews + hand btop for identity themes**
-  `executive-slate` and `neon-glass` lack `preview.png` (picker
-  plain-name rows). All three still ship generated btop only (no hand
-  `btop.theme`). `boreal` now has a `preview.png` (2026-07-09) but it's a
-  **headless theme-shot capture** — a clean bare desktop+bar, not the
-  floating-terminal (fastfetch+btop) composition the other 21 use; a
-  real-hardware recapture to match the grid would be nicer (VM is the
-  documented fallback). CSS/jsonc for boreal/executive-slate are solid.
-  Capture the other two after neon-glass is fixed/quarantined. Cost:
-  asset capture + optional hand btop; V3 visual.
