docs(quality-house): note Freewrite Sailfish firmware and rescore W1/W5/W9

Browse Source 
The Sailfish firmware (2025-11-19) rewrote the Freewrite Traveler OS in
Rust, cut keystroke latency 40–100 %, and trimmed power draw -30 %
typing / -50 % idle. Three rows are bumped: W1 3→4, W5 3→4, W9 1→2.
Freewrite now ties reMarkable at 42; Pomera still #2 at 45.

Freewrite Traveler scores assume the
[Sailfish firmware](https://getfreewrite.com/blogs/writing-success/freewrite-sailfish-firmware)
(released 2025-11-19), which rewrote the OS in Rust, cut keystroke latency
40–100 %, and trimmed power draw −30 % typing / −50 % idle on both
Traveler and Smart Typewriter Gen 3. Three Traveler rows were rescored
upward as a result: W1 3→4 (latency now plausibly inside 200 ms), W5 3→4
(boot accelerated, no published number), W9 1→2 (Rust rewrite explicitly
unblocked features that JS could not carry; still closed so it can't
reach reMarkable's hackable-Linux 3). The Smart Typewriter rows could be
bumped on the same basis but are left at pre-Sailfish values pending a
separate decision.

| W1 | Sub-second response to typing | 4 | 3 | 3 | 2 | 5 | Ours targets ≤200 ms; reMarkable + Frw.S (e-ink) visibly laggy, Smart's larger panel slower than Traveler; Pomera LCD ~zero. |
| W1 | Sub-second response to typing | 4 | 3 | 4 | 2 | 5 | Ours targets ≤200 ms; reMarkable e-ink laggy; Frw.S still slow (larger panel); Frw.T post-Sailfish trimmed latency 40–100 % (plausibly inside 200 ms); Pomera LCD ~zero. |
| W2 | Publishing is one deliberate action away | 5 | 4 | 4 | 4 | 2 | Ctrl-G atomic; reMarkable + Freewrite cloud-sync is one-tap but not git; Pomera = USB/SD copy or QR transfer. |
| W3 | Pulling power never corrupts the file | 4 | 4 | 2 | 2 | 2 | Ours: atomic-rename + fsync. reMarkable journals. Freewrite + Pomera: forum reports of corruption on yank. |
| W4 | Provisioning never interrupts writing | 5 | 2 | 2 | 2 | 5 | Ours v0.1: build-time config (dev-only). reM/Frw need Wi-Fi + account. Pomera: literally none. |
| W5 | Quick boot to a writing cursor | 4 | 3 | 3 | 3 | 5 | Ours target ≤5 s. reMarkable cold-boots ~20 s (great from sleep). Both Freewrites ~10–15 s e-ink wake. Pomera ~3 s. |

| W6 | Long sessions without crash / lag / drift | 3 | 3 | 4 | 4 | 5 | Ours unproven (1 h target). Freewrite famously stable (both variants). Pomera firmware is decades-mature. |
| W7 | Nothing on the device competes with prose | 5 | 2 | 5 | 5 | 5 | reMarkable has apps, menus, drawing, PDFs. Freewrite + Pomera are single-purpose; ours by design. |

Pomera ranking second is the useful signal — we're effectively building
Freewrite Traveler 42, reMarkable 42 (tied after Sailfish — pre-Sailfish
Traveler totalled 39), Freewrite Smart Typewriter 38. Pomera still
ranking second is the useful signal — we're effectively building
"Pomera + Wi-Fi + git + hackable BOM", which re-confirms the
differentiation thesis from `README.md`.
