 # M1 — Wi-Fi Service, Wi-Fi Tools, IRC
 
+**Status:** done on 2026-10-03, tagged `v0.2.0`.
+
+## Outcome
+
+The "Done when" items below work on the device, against irc.libera.chat over TLS, with the following changes.
+
+- **Changed:**
+  - **Wi-Fi Tools is built from ordinary scans only:** networks nearby, channel occupancy and a signal tracker. Monitoring-mode views and captures are deferred (revised Q42). The Monitoring mode stays in the Wi-Fi Service and the IRC pause logic, unused for now.
+  - **The frame buffer is 8-bit colour** (Q46), applied as soon as IRC on TLS measured a 51 KB low.
+- **Not done, carried over:**
+  - **Probe-request logs and Wi-Fi captures** are still listed as Storage Clean-up categories, but nothing writes to them yet.
+  - **IRC has no input history** (up-arrow recall). Each Buffer keeps only 50 lines in RAM; the full history is in the Logs.
+- **Measured on the device:**
+  - With Wi-Fi and IRC on TLS: about 92 KB free heap, about 77–81 KB at the lowest. The floor was 40 KB.
+  - 44% of the app flash used.
+  - 231 host tests.
+
 **Goal:** the device joins your Wi-Fi by itself, syncs its clock, keeps an IRC session alive in the background, and gives passive Wi-Fi diagnostics with full-frame captures.
