The daemon reads the Windows "now playing" media session (WinRT SMTC) and
adds np/nt/na to the BLE payload; the watch shows a play/pause glyph, a
scrolling title, artist and status. Best-effort and token-independent, so
it works even when the rate-limit data is unavailable.
Cyrillic titles: Styrene B has no Cyrillic glyphs, so the title/artist use
new composite fonts (font_styrene_cyr_{28,20}) — Latin from Styrene B,
Cyrillic + typographic punctuation from Montserrat, merged by lv_font_conv.
Latin titles stay on-brand; only Cyrillic falls back to Montserrat.
- daemon: read_now_playing() via winrt-Windows.Media.Control (lazy import,
never raises; PLAYING->1, PAUSED->2, else 0; title/artist truncated,
empty fields omitted)
- firmware: UsageData np_state/np_title/np_artist + parser; the real Now
Playing screen replaces the shared stub (SCREEN_NOWPLAYING)
- fonts: assets/Montserrat-Medium.ttf, font_styrene_cyr_{28,20}.c
- tools: patch_lvgl9_font.py (automates the 4 LVGL 9 font patches),
screenshot_win.py (Windows serial screenshot via pyserial + Pillow)
- README: document Cyrillic composite font generation
Verified on hardware (waveshare_amoled_206): idle state, a live Latin
title (scrolling), and Cyrillic (Prohozhdenie / Dunduk) all render.

In a managed Agent-SDK environment `claude login` is unavailable, so once
the stored access token expired the 5h/7d rate-limit % went dark forever.
The daemon now renews its own access token from the stored refreshToken via
the standard Claude Code OAuth refresh grant and writes the rotated tokens
back atomically (temp + os.replace, so a crash can't corrupt the file that
both the daemon and Claude Code read).
- proactive: refresh ~300s before expiry, checked each poll cycle
- reactive: on a genuine API 401, force one refresh + retry the poll once
- refresh tokens rotate on every use -> always persisted
- never raises: any refresh failure is logged and the loop continues
- secrets never logged (only lengths / expiry); error bodies are {"error":..}
Endpoint + client_id verified empirically against a live refresh
(HTTP 200, expires_in=28800).

The Session screen's tokens/cost are computed locally from transcripts and need
no network, but they were gated behind a successful rate-limit API call — so an
expired OAuth token or API outage froze the whole watch.
Daemon: always compute and send local usage every cycle; rate-limit utilization
is now best-effort and merged on top when available, with ok=true only when it's
fresh (ok=false on expired token / API down). poll_api returns just the
rate-limit fields; connect_and_run owns the payload + ok flag.
Firmware: ui_update always refreshes the Session screen; the rate-limit bars and
the freshness clock update only when data->ok, so the usage view falls back to
its existing idle "Zzz" state instead of showing stale or zeroed percentages.
Verified: with the token expired (HTTP 401) the daemon still sends
tk/tc/tn/to + ok:false and the Session screen keeps updating.

Pulling the USB Bluetooth dongle made BleakScanner raise from inside the main
loop; the exception propagated out of daemon_main, the bg thread died, and the
tray froze on its last state with no recovery (reported: "daemon crashed and
doesn't come back").
Two layers of hardening:
1. main() loop now wraps scan+connect in try/except — adapter-gone errors are
logged, the tray shows Scanning, and it backs off and retries, so replugging
the adapter recovers automatically. CancelledError is re-raised.
2. The tray supervises the asyncio loop: an unexpected crash is logged and the
loop is RESTARTED after a backoff, gated by a quit_evt so Quit still stops
cleanly (and call_soon_threadsafe is guarded against a closed loop).

Two bugs made the Session numbers wildly inflated (~$300/122M when the real
figures were ~$46/57M):
1. No de-duplication. Claude Code copies prior history into a new transcript
file on every compaction/resume, so the same API turn appears in several
.jsonl files. Summing all lines counted each turn multiple times — ~2.7x
inflation today (a heavily-compacted session). De-dup by (messageId,
requestId), matching ccusage.
2. Wrong Opus pricing. Used the older $15/$75 in/out rates; claude-opus-4-x is
actually $5/$25 (cache-write $10, cache-read $0.50) — 3x too high. Rates
verified against ccusage/LiteLLM, which they now reproduce to 100%.
Verified end to end against a fresh ccusage run: total tokens, output tokens and
cost all match exactly (57,256,809 tok / $45.63). Daemon-only change; no firmware
reflash needed.

The total is ~97% cache reads, which reads as implausibly large on its own.
Show the cache-inclusive total as the headline token number and the output
tokens ("what Claude actually generated", ~1.1M) as a small line beneath it —
impressive total, believable sub-number. Daemon sends a new `to` field; firmware
parses output_today and renders it. Re-spaced the Session layout for the 5th row.

Daemon: compute_today_usage() sums today's Claude Code token usage across the
local project transcripts (~/.claude/projects/**/*.jsonl), reading only files
modified today so the scan stays cheap, and prices it with Anthropic list rates
to show the equivalent API cost (the ccusage-style flex for subscription users).
The compact fields tk (total tokens), tc (cost in cents) and tn (message count)
piggyback onto the existing 60s BLE payload.
Firmware: UsageData gains tokens_today (64-bit) / cost_cents_today /
messages_today; parse_json reads tk/tc/tn; a new Session screen shows the cost
as the hero with total tokens and message count below, refreshed from ui_update
so it's current whenever opened. Wire SCREEN_SESSION to the real screen (was a
stub). Verified end to end: daemon sends e.g. tk=105374109 tc=26838 tn=663.

- New board firmware/src/boards/waveshare_amoled_206/ (CO5300 410x502,
FT3168 touch, AXP2101 PMU, QMI8658 IMU). PlatformIO env
waveshare_amoled_206. CO5300_COL_OFFSET=22, fixed orientation,
PWR button on GPIO10, FocalTech inline touch reader.
- Windows daemon: fix advertised device name (Claude Controller ->
Clawdmeter) to match firmware ble.cpp, and add CLAWDMETER_ADDRESS env
fallback so it connects by address when the bonded HID device is not
advertising (Windows keeps it HID-connected).
