+# KOTA Sensorbox Technician Tool
+
+Diagnoza sensorboxa przez USB, wgrywanie firmware z folderu `firmware/` i przygotowanie karty SD.
+Działa na Windows 10/11 i macOS 13 (Ventura) lub nowszym, na Macach z Intelem i Apple Silicon.
+
+Repozytorium: https://gitea.kota-app.com/kkallas/kota-technician-tool (dostęp nadaje właściciel repozytorium).
+
+## Dla technika: dwa pliki
+
+| System | Aktualizacja | Uruchomienie |
+|---|---|---|
+| Windows | `update_windows.bat` | `run_windows.bat` |
+| macOS | `update_macos.command` | `run_macos.command` |
+
+- **Aktualizacja** sprawdza na Gitea najnowszą wydaną wersję i pobiera tylko to, co się zmieniło
+  (pliki programu, firmware i potrzebne biblioteki). Uruchom ją, gdy firmware team ogłosi nową wersję,
+  albo po prostu przed wyjazdem do klienta. Pokazuje, co się zmieniło.
+- **Uruchomienie** startuje program. Nie łączy się z Gitea, działa też bez internetu (po pierwszej aktualizacji).
+
+Nie trzymaj folderu narzędzia w Google Drive ani OneDrive.
+
+## Pierwsza instalacja (raz na komputer)
+
+1. Na Gitea otwórz **Releases** i przy najnowszej wersji pobierz **Source Code (ZIP)**.
+2. Rozpakuj do zwykłego folderu, np. `Dokumenty\KOTA\technician-tool` (macOS: `~/Documents/KOTA/technician-tool`).
+3. Uruchom plik aktualizacji dla swojego systemu. Za pierwszym razem:
+   - połączy folder z Gitea i zapyta o login do Gitea (hasło lub token); system je zapamięta,
+   - zainstaluje brakujące narzędzia za Twoją zgodą: Git (Windows: przez winget; macOS: Apple Command Line Tools
+     - po ich instalacji uruchom aktualizację jeszcze raz) oraz `uv` (menedżer Pythona, tylko dla bieżącego
+     użytkownika),
+   - pobierze biblioteki Pythona (1–2 minuty, potrzebny internet).
+4. Uruchom program plikiem `run_...`.
+
+**macOS:** jeśli Finder odpowie, że pliku nie można uruchomić (zdarza się po rozpakowaniu zip), otwórz Terminal,
+wpisz `bash ` (ze spacją), przeciągnij `update_macos.command` do okna i naciśnij Enter. Po pierwszej aktualizacji
+oba pliki `.command` dają się już otwierać dwuklikiem.
+
+Zamiast zip można też zrobić `git clone https://gitea.kota-app.com/kkallas/kota-technician-tool.git` i dalej
+używać tych samych dwóch plików.
+
+Konkretna starsza wersja (np. do serwisu nietypowego boxa): w folderze narzędzia `git switch --detach v0.8`;
+kolejna aktualizacja wraca do najnowszej.
+
+Wszystkie wersje używają jednego środowiska Pythona poza folderem narzędzia:
+`%LOCALAPPDATA%\KotaTechnicianTool\venv` (Windows), `~/Library/Caches/KotaTechnicianTool/venv` (macOS).
+Stare środowiska `venv-0.x` z poprzednich wersji można usunąć.
+
+Sesje, kopie zapasowe flash i ustawienia są w `~/KotaTechnicianTool` (Windows: `C:\Users\<użytkownik>\KotaTechnicianTool`).
+
+## Port sensorboxa
+
+- Windows: `COMx - Sensorbox (native USB) [MAC]`
+- macOS: `/dev/cu.usbmodemXXXX - Sensorbox (native USB) [MAC]`
+
+Kabel USB musi przenosić dane (nie tylko ładowanie). Przy restartach z komunikatem o brownout użyj innego portu
+lub zasilacza.
+
+## Firmware
+
+Wgrać można tylko pliki `.bin` z folderu `firmware/`. Lista pokazuje datę kompilacji zapisaną w pliku,
+najnowszy build jest na górze. Nowy build: wrzuć plik do `firmware/` i kliknij **Refresh list**.
+
+## Dla zespołu
+
+- Praca nad zmianą: gałąź (`git switch -c feature/<nazwa>`) → commity z przechodzącymi testami →
+  `git push -u origin feature/<nazwa>` → pull request na Gitea → merge do `main`.
+- Wydanie wersji: numer w `pyproject.toml`, `kota_tech/__init__.py` i `uv.lock`, tag `vX.Y`
+  (`git tag -a vX.Y -m "Technician tool vX.Y"`, `git push origin vX.Y`), opis w **Releases** na Gitea.
+  Aktualizacja techników bierze **tylko tagi `v*`** – zmiany w `main` bez tagu do nich nie trafiają.
+- Nie commitujemy `ENV.TXT` z prawdziwym tokenem ani haseł Wi-Fi.
+- Testy:
+
+```
+uv run --frozen pytest -q
+```
+
+Zmiany w wersjach: `docs/CHANGES-v0.*.md`; historia v0.1–v0.8 jest w tagach gita.

+# Technician tool v0.8 - changes
+
+## Windows + macOS
+- Dependencies verified to install on macOS arm64 and x86_64 (uv.lock: PySide6 6.11 universal2 wheels,
+  requires macOS 13+); Windows unchanged.
+- SD card check: macOS `diskutil` reports FAT32 partitions as `DOS_FAT_32` / `Windows_FAT_32`; these are now
+  accepted (previously a correct card was reported as "not FAT32" on a Mac).
+- Unit tests for the macOS serial-port filter (`/dev/cu.*` only) and FAT32 names.
+- README.md with launch steps for both systems (incl. the Google Drive executable-bit workaround on macOS);
+  docs/mac_agent_command.txt updated for a v0.8 test run on a Mac.
+
+## Diagnosis
+- Harmless Wi-Fi start-up errors are ignored (rule `benign.wifi_start`): `wifi:sta is connecting, return error`,
+  `esp_wifi_connect() failed: ESP_ERR_WIFI_CONN`, `Failed to get configured network when updating network
+  status` (unpaired box).
+- Brown-out resets are detected (`E BOD: Brownout detector was triggered`, ROM reports RTC_SW_SYS_RST).
+- Service report note = the Diagnosis panel as text (LED, firmware, box self-report, start-up progress with
+  times, findings with "Seen Nx, first at ... s, last at ... s" and log line), shortened to fit the service
+  form's 5000 characters.
+
+Not yet run on a real Mac: see docs/mac_agent_command.txt.

+# Technician tool v0.9 - changes
+
+- Two files per system for technicians: `update_windows.bat` / `update_macos.command` (update) and
+  `run_windows.bat` / `run_macos.command` (start).
+- Update: checks Gitea for the newest release tag `vX.Y`, downloads only what changed (git), shows the list of
+  changes, protects files edited by hand (asks first), connects a folder unpacked from a release zip on first
+  run, installs git / uv when missing (asks first) and brings the Python libraries up to date.
+- One shared Python environment for all versions: `KotaTechnicianTool/venv` (was `venv-0.x` per version).
+- A developer copy on a branch is left alone by the update script (use `git pull`).

 Tests, in order. Report pass/fail with evidence for each:
 1. Launch: `bash run_macos.command` (it offers to install uv). The app window opens; note any warnings.
-2. Tests: `UV_PROJECT_ENVIRONMENT="$HOME/Library/Caches/KotaTechnicianTool/venv-0.5" uv run --frozen pytest -q`
+   Also check whether a double-click in Finder works (Google Drive may drop the executable bit).
+2. Tests: `UV_PROJECT_ENVIRONMENT="$HOME/Library/Caches/KotaTechnicianTool/venv-0.8" uv run --frozen pytest -q`
+   (expect 172 passed).
 3. Serial: plug in the sensorbox (native USB). The port list shows a /dev/cu.usbmodem* "Sensorbox (native USB)"
-   entry with a MAC. Connect, press "Reset & capture": the boot log starts at "ESP-ROM:esp32s3" and the
-   Diagnosis panel identifies firmware v1.0 (build 45fa9d5b9). Check whether the port disappears after the
-   reset and whether the tool reconnects.
-4. Guided troubleshooting: run "Quick check" and answer truthfully with what I tell you the LED shows.
-5. Flash (App only, factory image; the box already runs it): the tool must enter flashing mode by itself,
-   write, restart the box and report "Success ... build 45fa9d5b9". Capture the esptool output.
-6. SD card tab: the settings load from ../../002-SD_card_format/ENV.txt. The card reader and card are listed
-   (internal disks must NOT be listed). Run "Check card", then, after my OK, "Format card and write ENV.TXT".
-   It must use `diskutil eraseDisk FAT32 KOTA MBRFormat` on the correct disk, write ENV.TXT byte-identical
-   to the template, and eject the card.
-7. "Service report..." opens the browser at https://service.kota-app.com/<MAC>#kota-report=... (it is fine
-   if the page itself cannot prefill yet).
+   entry with a MAC (no /dev/tty.* duplicate). Connect, press "Reset & capture": the log starts at
+   "ESP-ROM:esp32s3" and the Diagnosis panel shows firmware v1.0.16 (build 4f10989e), the "Box self-report"
+   section and the LED with its pattern. Check whether the port disappears after the reset and whether the
+   tool reconnects. Wait 2 minutes: a "KOTA: health" line appears every 60 s.
+4. Show filter "KOTA diagnostics + errors" shows only KOTA lines and errors.
+5. Guided troubleshooting: run "Quick check" and answer truthfully with what I tell you the LED shows.
+6. Flash (App only, the newest file in firmware/, chosen by its compile date): the tool must enter flashing mode
+   by itself, write, restart the box and report "Success ... build 4f10989e". Capture the esptool output.
+7. SD card tab: the card reader and card are listed (internal disks must NOT be listed). "Check card" must NOT
+   report a wrong file system for a FAT32 card. After my OK, "Format card and write ENV.TXT" must use
+   `diskutil eraseDisk FAT32 KOTA MBRFormat` on the correct disk, write ENV.TXT and eject the card.
+8. "Service report..." opens the browser at https://service.kota-app.com/<MAC>#kota-report=...; the note in
+   the form must match the Diagnosis panel (self-report, start-up progress with times, findings with
+   "Seen Nx, first at ... s").
 
 At the end, write a short report: macOS version, Mac model/architecture, each test with result, errors, and
 suggested fixes (file:line).
