icount throttled TCG and starved the guest watchdog. Measured book open dropped from 146s to 31s. Off by default; ?icount restores it, ?noicount removed in favor of the new default. Harness now reports open-file timing.
The file browser no longer auto-seeds, so the headless test seeds Test/example.txt into OPFS before autoboot. Docs corrected: store-containing-TB TCI is upstream qemu-wasm design (compiled store path is not rewind-safe), not a port bug.
Add directory navigation, folder creation, inline deletion, clear controls, and a focused editor view. Include the opt-in FAT16 vvfat experiment and fail-fast browser diagnostics; raw FAT32 remains the default.
Bumps third_party/qemu to the wasm32 store-TB TCI workaround so the
browser reader no longer panics in uzlib font decompression. Adds
docs/wasm-inflate-panic.md with the full investigation (native control,
non-deterministic reject, JIT promotion) and next steps. Updates ISSUES:
the panic is worked around; the reader now inverts into muddled
grayscale after the initial BW page (new top reader defect). tests
navigate the 4th Open press into the reader.
Browser SD files are persisted in OPFS (web/sdstore.js) and edited in the
Files tab. At boot the browser builds a deterministic 64 MiB FAT32 image
(web/fat32.js) with nested directories and VFAT long names, then mounts
it as a raw block device, bypassing QEMU's broken populated-vvfat WASM
coroutine path. Guest writes mutate only the ephemeral image.
Exposes a hidden #frame-generation indicator that increments on every
e-ink flush, so automation can wait on real display updates instead of
fixed sleeps. Adds tests/ with a Makefile runner: 'make test' for JS +
FAT32/mtools checks, 'make browser-test' for a headless-Firefox boot of
the official CrossPoint 1.4.1 firmware that navigates to
Test/example.txt. Bumps third_party/qemu to the SPI-SD/CMD13 fixes and
updates README/ROADMAP/ISSUES for the new architecture.
