Pairs with :gl as the push half of the git pair. Same behavior
(fmt → save → commit → push); notices, logs, and current READMEs
follow, historical docs keep :sync as a record of their time.
Run 4 (2026-07-13): remote.push() consumed ~6 MB of PSRAM over 66 s and
the UI thread aborted on Frame::new_white's per-draw vec![0xFF; 26928].
Run 5 confirmed the UI now survives, but the push still exhausts both
pools (a ~7 KB inflateInit fails inside the pack build) and the heap
telemetry never fired — hence the telemetry rework.
- display/editor: Editor::draw_into() renders into a caller-owned
Frame; main.rs keeps two boot-time frames (shown/back) and mem::swaps
on success, so steady-state repaints never allocate.
- git_sync: odb cache capped at 1 MB via raw libgit2-sys opts (git2
0.20 doesn't wrap the total cap); log_push_heap at pre-push,
post-push and push-failure with largest-PSRAM-block and per-pool
min-evers; pack_progress logging is now time-gated (2 s) — the
count gate (+256 objects) never fired because AddingObjects reports
total=0 and a small push inserts only dozens of objects.
- editor: empty/whitespace snippets file parses as 0 snippets instead
of a JSON error at boot.
- build.rs: refuse a git-feature build with unset TW_* publish vars —
a bare `cargo build --features git` baked empty creds and produced a
firmware whose :sync could never work.
Generalise the palette so Enter advances any pref to its next value and
wraps; a boolean toggle is the two-option case. Both string prefs share a
next_option(current, &OPTIONS) helper (off-list values snap to the head).
- theme (light/dark): rendered as a single whole-frame Frame::invert at the
end of draw(), so text, selection, caret, panel and palette flip together.
- auto_sync: cycles 2m/5m/10m/15m/30m. Set-ahead only — still read by
nothing until the v0.7 periodic push.
toggle_pref -> cycle_pref; palette hint "Enter toggle" -> "Enter change".
Land the v0.1 editor integration: the git_sync module (libgit2 on the SD
/sd/repo, dedicated 96KB git thread, lazy Wi-Fi, :sync push with
synced/up-to-date/failed snackbars), the boot splash (Spike 9) plus its bin
and justfile recipes, and a power-on→cursor boot-timing log. Also re-syncs
the roadmap/spikes/v0.1-product status and adds the SD hardware reference
photo.
Move the editor core out of the firmware crate (pinned to the xtensa
target, so it can't run `cargo test`) into a standalone `editor` crate,
with the panel framebuffer + geometry split into a `display` crate. Both
depend only on embedded-graphics + keymap, so the editor is now
host-buildable and unit-tested (8 characterization tests). Firmware links
them and re-exports the geometry from epd.rs; behaviour is unchanged.
The xtensa firmware build was not verified in this environment.
