+## Update: 23:50 PT — gap 1 + gap 2 closed: survey-collect + dfs-check built; SKILL marked wifi-working / switches-WIP
+
+GAP 1 (fold ad-hoc recipes into reusable collectors) — DONE, both validated on Cascades:
+- **survey-collect.sh** `<site> [ap-ssh-vault-path]` — per-AP per-channel busy%/noise from
+  `iw survey dump` -> in-use busy% + cleanest non-DFS channels per band. 72 APs reported.
+  Result: 2.4 saturated 94-97% on every channel; 5GHz cleanest non-DFS = ch36/48/153/161; 6GHz ~0%.
+- **dfs-check.sh** `<site> [ap-ssh-vault-path]` — per-AP `dmesg` radar history, PRECISE patterns
+  (excludes the "cached ifindex" false-positive). Result: **55/75 APs on DFS, ZERO real radar
+  events fleet-wide** -> DFS empirically low-risk at Cascades despite Davis-Monthan proximity
+  (confirms the retry-rate finding; the DFS concern was theoretical).
+
+GAP 2 (scope) — DONE via SKILL.md Status block: WiFi monitoring+tuning = **WORKING** for every UOS
+site we monitor (audit-site, live-stats, model-rank, optimize-radios, survey-collect, dfs-check,
+neighbor-collect, watch-ap, apply-radio — all site-parameterized). Switches/PoE, gateway/WAN/
+firewall, adoption = **WIP** (access layer reaches them; need dedicated collectors). Per-client:
+vault each client's own `clients/<x>/unifi-ap-ssh`, pass as the script arg.
+
+CROSS-PLATFORM LESSON (baked into both new scripts): pass temp paths to python via ARGV — MSYS
+translates POSIX->Windows for python.exe; `$TMP` embedded in a `python -c` string is NOT translated
+and fails ("No such file or directory") on Windows. Use `python - "$TMP/x" <<'PY' ... sys.argv[1]`.
+
+Coord: collectors+status announce c3ccaa07. Next: wire neighbor-collect redundancy into
+optimize-radios.sh; Floor-4 2.4 power-down pilot (still nothing applied to live radios).
