-### 89. Tray icon parity — themed overrides for SNI apps (Bernardo 2026-07-11)
-The bar is monochrome; third-party tray icons aren't. EasyEffects 8's Qt
-SNI publishes IconName `com.github.wwmm.easyeffects` → Papirus full-color
-blue (T14s V3, 2026-07-11); Signal / Telegram / ZapZap (all flatpaks on
-the T14s) likely worse. Goal: every tray icon reads like part of the bar.
-
-Slices:
-1. **Inventory — DONE (T14s live session, 2026-07-11):**
-   | app | IconName | pixmap? | verdict |
-   |---|---|---|---|
-   | nm-applet | `nm-signal-*` (state-varying) | no | **name-based** — override the `nm-*` family |
-   | udiskie | `drive-removable-media-usb-panel` | no | **name-based** |
-   | Telegram | `org.telegram.desktop[-mute/-attention]-symbolic` | yes (fallback) | **name-based** — ship all state names |
-   | Signal | `Signal_status_icon_1` (generated, not a real theme name) | yes | **pixmap** — slice 3 |
-   | ZapZap | *(empty)* | yes | **pixmap** — slice 3; check its own tray-style setting first |
-   | EasyEffects 8 | `com.github.wwmm.easyeffects` (prior T14s finding) | — | **name-based**; NB `--gapplication-service` alone registers no SNI |
-
-   **Bernardo's visual verdict (T14s, 2026-07-11):** Telegram and ZapZap
-   already read fine on the bar — out of scope. The offenders are
-   **EasyEffects** (slice 2: name-based override) and **Signal**
-   (slice 3: pixmap; check for an app-side tray option, else document).
-   Related fix shipped same day: easyeffects.service now *waits for a
-   registered tray host* before starting (the old After=waybar.service
-   ordering was inert — waybar is supervisor-run, not a unit), so the
-   icon no longer vanishes on unlucky boot order.
-2. **Override layer — DONE (EasyEffects, 2026-07-12, f9d5e2c…b98248f).**
-   Chosen mechanism: a `Nomarchy-icons` child theme (built in
-   `modules/home/theme.nix`) that `Inherits` the resolved icon set and
-   becomes the session icon theme; a scalable, palette-`text`-coloured
-   monochrome override out-resolves the parent's fixed-size icon at every
-   size while all other icons fall through. Single shared layer → holds
-   for every theme (all resolve to Papirus-*), colour regenerated per
-   switch. V3 in Boreal (Bernardo confirmed). Extend to a new name-based
-   offender = one more SVG in `scalable/apps`.
-3. **Pixmap apps:** document (or wire, where a setting exists) per-app
-   monochrome/tray options; what can't be fixed goes in the item's
-   record, not silent scope creep. **Signal** is the live example
-   (`:1.227`, generated pixmap → shows as its full-colour blue round
-   icon on the bar); still open.
-
-V-path: V1 eval + icon file lands in the right lookup dir; V3 screenshot
-of the tray on a real session (headless VM has no flatpak chat apps).

+## 2026-07-12 — #89 slice 3: Documented Signal tray icon limitation (no commit)
+- **Task:** BACKLOG #89 slice 3 — Signal's tray icon is full-colour blue and doesn't match the monochrome bar.
+- **Did:** Researched Signal's Linux tray icon behavior. Found it is a hardcoded, dynamically generated pixmap (`Signal_status_icon_1`) driven by its Electron wrapper with no built-in toggle for a monochrome icon. Added an entry to `docs/ROADMAP.md`'s known issues noting that certain Electron apps cannot be natively themed. Closed out #89 from the backlog without introducing brittle `app.asar` repacking hacks.
+- **Verified:** N/A (Documentation only).
+- **Pending:** #89 is fully closed.
+- **Next suggestion:** Pick the next item from the BACKLOG.

 ## Known issues & follow-ups
+- **Signal (and some Electron apps) tray icon cannot be themed** (BACKLOG #89, 2026-07-12): Signal Desktop hardcodes a dynamically generated, full-color pixmap (`Signal_status_icon_1`) via its Electron wrapper and pushes it directly over SNI. It ignores GTK icon themes and provides no built-in toggle for a monochrome icon. We will not use brittle `app.asar` repacking overlays to override this due to maintenance overhead and scope creep. It is expected that its tray icon will not match Nomarchy's monochrome bar.
