# Macroplan — version details

Frequent releases. Each version is a usable artifact, not a checkpoint.
This file holds the `macroplan` source block (below) and the per-version scope.
The user-facing requirements and engineering targets each release feeds into are
tracked in [`qfd.md`](qfd.md).

## Status — synced 2026-07-11

The editor **core** has been built 2–3 versions ahead of the device
**releases**, and is now **extracted into a host-testable `editor` crate** (plus
a `display` crate for the panel framebuffer) so `cargo test` exercises it off the
xtensa target. **v0.1 shipped 2026-07-11** (late against the 2026-06-29
baseline): SD storage, save, and **git publish are all wired into the app binary
and hardware-verified** (`:sync` commits on the SD `/sd/repo` and pushes to a
test repo), and the **boot splash (Spike 9) is confirmed on the panel** — a
vector `typoena`-in-a-circle shown at startup while the SD mounts, then the
editor comes up. **Cold boot verified at 4258 ms** (power-on → cursor,
2026-07-11; 742 ms under the ≤ 5 s gate). It first measured ~5.5 s; the fix was
to bring the editor up with a full-area partial (~630 ms) instead of a second
full refresh (~1.9 s) — panel confirmed clean, no ghosting. The 1-hour soak is
attested from real use; the remaining post-ship acceptance checks are power-pull
recovery, 1000-word no-drop, and `Ctrl-G`'s not-yet-built pull-then-retry
(→ v0.9). **v0.2 navigation is COMPLETE 2026-07-11** — Spike 13's on-panel gutter
refresh check passed (single-line edit repaints only rows at/below it, no extra
full refresh), closing the last gate. **v0.2.5 international input** is
hardware-verified (2026-07-11), and **v0.3 editing is complete in core** the same
day (register + yank/paste, snapshot undo/redo, `.` repeat — host-tested, and
partially smoke-tested on the panel: `dd`/`yy`/`Ctrl-r` good, a multi-line-paste
scroll bug found + fixed). **v0.4 visual + ex is complete in core** the same day
too — charwise/linewise **Visual** selection (`v`/`V` with `y`/`d`/`c`), the
read-only View mode moved to `gr`, and the selection drawn as reverse-video on
the panel; `:e` was deferred to v0.5. Host-tested (83 editor tests); on-device
smoke-test pending. The firmware crate is bumped to **0.4.0**. Most of v0.6
Markdown also already runs. Version numbers track shippable device releases, not
raw core progress — the 0.4.0 bump reflects the v0.4 feature set being met.

Marks: `[x]` done in core · `[~]` partially done · `[ ]` not started. An
inline `(✓)` marks the done half of a split item.

## v0.1 — MVP: "it writes, it pushes" — [x]

The minimum thing that justifies the hardware existing. Full design:
[product](v0.1-mvp-product.md) · [technical](v0.1-mvp-technical.md).

**Status:** SHIPPED 2026-07-11 (late vs the 2026-06-29 baseline). Core editing +
partial refresh run on device; **SD mount + save are wired into `main.rs`**
(Spike 3 resolved — a genuine ≤32 GB card mounts, verified on its own SPI3 host
per ADR-012); **git publish is wired** (`:sync` → commit + fast-forward push on
the SD `/sd/repo`, hardware-verified against a test repo); and the **boot splash
(Spike 9) is confirmed on the panel** — [`Frame::splash`](../display/src/lib.rs)
shows a vector `typoena`-in-a-circle at startup while the SD mounts, then the
editor comes up. Cold boot **verified at 4258 ms** (power-on → cursor, 2026-07-11; 742 ms under
the ≤ 5 s gate). It first measured ~5.5 s; the fix was to bring the editor up
with a full-area partial (~630 ms) instead of a second full refresh (~1.9 s) —
panel confirmed clean. The 1-hour soak is attested from real use; the remaining
post-ship acceptance checks are power-pull recovery, 1000-word no-drop, and
`Ctrl-G` pull-then-retry (→ v0.9) — see
[product → acceptance](v0.1-mvp-product.md#acceptance-criteria).

- [x] ESP32-S3 boots (✓); e-ink shows Typoena splash (✓ Spike 9, confirmed on
      panel 2026-07-11); boot status surfaces via the panel snackbar (no serial on device)
- [x] USB host enumerates the Nuphy, key events reach the editor (Spike 4)
- [x] One hard-coded file (`/sd/repo/notes.md`) opens on boot — **wired in
      `main.rs`** (`boot_storage` mounts the SD and loads the note; a missing
      card / repo / unreadable note halts with a panel message). The card is
      pre-seeded from a computer (`just init` copies a full clone to `/sd/repo` +
      writes config), never cold-cloned on device — see
      [note](notes/git-sync-images-and-repo-size.md).
- [x] Insert-only editing, backspace, enter, arrow keys — modal editor overshot this early (see v0.2)
- [x] Line wrap, no line numbers yet — soft-wrap done early (see v0.6)
- [x] Save to SD via `:w` (and `:sync`) — **wired in `main.rs`** through the
      `persistence` module's atomic write (unlink-then-rename + `*.tmp`
      boot-recovery)
- [~] Wi-Fi credentials + remote URL + PAT + author: today baked into the binary
      via `env!()` (no NVS, no on-device provisioning UI in v0.1). Migrating to
      `/sd/typoena.conf` on the card, provisioned by `just provision` (or
      `just init` for a fresh card) from the same `firmware/.env` the build uses
      (minimum input — rotate the PAT or switch networks without a reflash, no
      card re-copy). Firmware to read it at boot instead of
      `env!()` — the git-publish wiring landed with baked config (2026-07-11);
      the `typoena.conf` migration itself is deferred to v0.9 (on-device
      provisioning).
- [x] Publish on **`:sync`** (the editor's command; originally planned as
  `Ctrl-G`): format (`:fmt`, when `format_on_save`) → save → stage `notes.md`
  → commit with a timestamp message →
  fast-forward `push`; on a rejected push, fetch + reconcile then retry once
  (no-op short-circuit when the tree is unchanged). **Wired into the editor and
  hardware-verified 2026-07-11** — `firmware::git_sync` opens the SD `/sd/repo`,
  runs on a dedicated 96 KB git thread with lazy Wi-Fi, and pushes over mbedTLS
  HTTPS+PAT; the panel snackbar shows `synced <oid>` / `up to date` /
  `sync failed`. (Interrupted-push auto-retry deferred to v0.9.)
- [x] Split the display into a **writing column** (60 cols) + a **side panel**
      (~30 cols at FONT_6X10) for metadata — the surface every later panel
      feature writes to. **Built** in the `editor` crate (`draw_panel`): a
      full-height divider at x=600, with the panel currently showing the word
      count, the mode indicator, a NO-KBD flag, and a transient save/publish
      **snackbar** (below). Later fields (filename, clock, Wi-Fi, battery) add to
      the same surface. Defined in
      [`CONTEXT.md` § Screen regions](../CONTEXT.md#screen-regions) and
      [product § Screen layout](v0.1-mvp-product.md#screen-layout).
- [x] **Snackbar** — a transient side-panel notice for host events (added
      2026-07-11). On-device there is no serial log, so boot posts `loaded
      <name>` (the note's filename without suffix), `:w` posts `saved` /
      `save FAILED - retry :w`, and `:sync` posts `syncing...` then the push
      result (`synced <oid>` / `up to date` / `sync failed`). Set via
      `Editor::set_notice`; cleared on the next keystroke
      rather than a timer — a timed auto-dismiss would cost a ~630 ms full-area
      e-ink flash purely to erase text, which the panel deliberately avoids (cf.
      the dropped pending-accent marker in v0.2.5).
- [x] Partial refresh on edits (✓ Spike 5); save wired (full-area partial
      repaint on `:w`)

Out of scope: Vim, palette, multiple files, branches, conflict handling.

## v0.2 — Vim navigation — [x]

**Status:** COMPLETE 2026-07-11. Navigation done in core; the **UTF-8-correct
buffer** and **`Ctrl-d/u` half-page scroll** landed and are hardware-verified,
and the **absolute line-number gutter** is built, host-tested, and **confirmed
on the panel (Spike 13) 2026-07-11** — a single-line edit repaints only the rows
at/below the change and forces no extra full refresh. Shipped early beyond scope:
a read-only **View** mode and the full `d`/`c` operator + text-object grammar
(see v0.3 / v0.4).

- [x] Mode state machine (Normal / Insert / View), mode indicator in the status strip
- [x] Movement: `h j k l`, `w b e`, `0 $`, `gg G`, `Ctrl-d Ctrl-u`. `Ctrl-d/u`
      step **display** (soft-wrapped) rows, not logical lines — half a page is
      half the visible window however prose wraps; decoded as `HalfPageDown/Up`
      intents in the keymap, caret moves and the viewport follows.
- [x] `i a o O A` to enter Insert
- [x] `Esc` returns to Normal
- [x] Line numbers in the left gutter: **absolute**, built + host-tested
      2026-07-11, **confirmed on the panel (Spike 13) 2026-07-11** — numbered on a
      logical line's first display row, blank on wrapped continuation rows; the
      gutter width tracks the buffer's line count (2 digits + separator, widening
      past 99 lines) and steals its columns from the soft-wrap. **Always on** in
      v0.2; the on/off toggle rides the v0.5 `.typoena.toml` prefs (below).
      Relative numbering was dropped (2026-07-11): renumbering the whole gutter on
      every `j`/`k` burns the e-ink ghosting budget for no proportionate gain,
      whereas absolute renumbers only the rows below an edit — the on-panel check
      confirmed a single-line edit repaints only rows at/below it with no extra
      full refresh.
- [x] Groundwork — UTF-8-correct buffer: caret motions and edits step by
      character, not byte (dropped the ASCII == byte-offset assumption), so every
      motion stays correct with accented input. **Done 2026-07-11** alongside
      extracting the editor into a host-testable crate — char-step
      motions/deletes, byte-vs-char split in `layout`/`caret_rc`, `word_end`/`de`
      fixed; 15 host tests. Render font is ISO-8859-15 (Latin-9), so accented
      glyphs display.

## v0.2.5 — International input — [x]

**Status:** DONE in core, **hardware-verified 2026-07-11** (typed ç é è ñ on the
bench, no crash). US-International dead-key accent composition lives in the
`keymap` crate — a `Composer` downstream of the decoder — wired into
`usb_kbd.rs` so the editor still receives a single `Key::Char`. Builds on the
v0.2 UTF-8-correct buffer and the ISO-8859-15 render font. Host-tested.

- [x] Dead keys — grave, acute, circumflex, diaeresis, tilde — compose with
      the next letter: à é ê ë ñ, ç (via `'`+c), both cases
- [x] `'`+space emits a literal apostrophe (the everyday apostrophe path); a
      dead key followed by a non-composing letter emits the accent then the
      letter
- [x] A non-character event (Enter, Backspace, arrows) flushes any pending
      accent as its literal first
- [ ] ~~Pending-accent indicator in the side-panel status strip~~ — **DROPPED
      (2026-07-11 decision):** at typing speed it would be stale before the
      ~630 ms panel repaint, so it conveys nothing. Left unbuilt on purpose.
- [x] Bonus (2026-07-11): the physical **Esc key** (HID 0x29) now types
      `` ` ``/`~` — Esc comes from the Caps tap — so grave/tilde accents and
      Markdown code fences are reachable on a 60% board without a Fn layer.

## v0.3 — Vim editing — [x]

**Status:** COMPLETE in core 2026-07-11, host-tested (65 editor + 28 keymap
tests) and **partially smoke-tested on the panel 2026-07-11**. The three
remaining pieces landed together: a single unnamed **register** with
`y`/`yy`/`p`/`P` (and `x`/`d`/`c` filling it, so `dd`…`p` moves a line),
**undo/redo** (`u`/`Ctrl-r`, snapshot-based, bounded to 100 groups in PSRAM — a
whole Insert session undoes as one group), and **`.` repeat** (keystroke-recorded,
so it replays an insert session like `ciwfoo<Esc>`). The `d`/`c` operator grammar
and text objects had already landed ahead of schedule. On device, `dd`, `yy`, and
`Ctrl-r` confirmed good; the one issue found was that a **multi-line paste near
the bottom left its later lines below the fold** — `adjust_scroll` only kept the
caret's (first) pasted line visible. Fixed by a `reveal()` that scrolls the end of
the pasted block into view while the caret stays on its first line (reflash to
re-confirm on panel).

- [x] `x dd`, `dw dd d$` (✓); `yy p P` (✓) and `.` repeat (✓) — register + a
      keystroke-recorded last-change both landed 2026-07-11
- [x] Undo / redo (`u`, `Ctrl-r`) — snapshot history bounded to 100 groups in
      PSRAM; one Insert session = one undo group
- [x] Numeric prefixes (`3dd`, `5j`)
- [x] Ahead of schedule: `c` change operator + text objects
      (`ciw`, `di(`, `ca"`, … — inner/around, nesting-aware)

Known limits (deferred): `.` drops a *leading* count (`3x` then `.` deletes one;
a count inside an operator like `d2w` is kept); no named registers; `.` after an
aborted operator (`d<Esc>`) is a no-op.

## v0.4 — Visual mode + ex commands — [x]

**Status:** COMPLETE in core 2026-07-11, host-tested (83 editor tests), on-device
smoke-test pending. Charwise **Visual** (`v`) and linewise **VisualLine** (`V`)
selection landed with `y`/`d`/`c` on the span: charwise is vim-inclusive of the
char under the further caret, linewise spans whole logical lines and fills the
register linewise (so `Vy`…`p` copies a line, `Vd` deletes it like `dd`). Motions
(`h j k l`, `w b e`, `0 $`, `gg G`, `Ctrl-d/u`) and counts extend the selection;
`v`/`V` toggle/switch submode, `Esc` cancels. The selection renders as
reverse-video cells (black fill, glyphs redrawn white) — the only selection
affordance on a 1-bit panel — with the caret cell punched back to *normal* video
so the active end stands out. The Normal-mode motions were factored into a shared
`move_by` helper so Normal and Visual can't drift.

**DECISION (2026-07-07, resolved 2026-07-11):** `v`/`V` = **Visual** selection
(vim-standard). The read-only **View** (reading/scroll) mode that used to sit on
`v`/`V` moved to **`gr`** (go-read) — a `g`-prefixed gesture reusing the existing
pending-`g` machinery, no vim clash. View mode stays; `v`/`V` are now Visual.

- [x] Visual char (`v`) and line (`V`) modes, `y d c` on selections — landed
      2026-07-11 (18 new tests). Known limits (deferred): no `o` swap-ends, no
      `x`/`s` operator aliases, no Visual `.` repeat, no `:'<,'>` range commands.
- [~] `:` command line (mechanism ✓; `:w`/`:wq`/`:x` save, `:fmt`/`:sync`/`:gl`
      wired; `:q` deliberately dropped — nothing to quit to). Command-line
      editing added 2026-07-11: Ctrl-W deletes the previous word, Cmd-Backspace
      clears the line. **`:e <path>` deferred to v0.5** — opening another file
      needs host file-IO + buffer switching, which is v0.5's multi-file work
      (gated behind Spikes 11/14); half-building it here ahead of its
      dirty-buffer handling wasn't worth it.
- [x] Ahead of schedule / unscheduled: `:fmt` Markdown formatter
      (table alignment, blank-line collapse, trailing-whitespace strip)

## v0.5 — File palette + multi-file — [~]

**Status:** buffer **foundation** landed in core 2026-07-11 (slice 1 of 4),
host-tested; the palette + transient panel (Spike 11) and delete → git-staging
(Spike 14) remain the on-device gates. The single-file `Effect` return became a
drained **effect queue** (`Save{path,contents}` / `Load{path}` / `Publish` /
`Pull`), so one action can ask the host for several steps in order — opening a
non-resident file queues a `Save` of the outgoing dirty buffer *then* a `Load` of
the target. The multi-buffer state deliberately avoids a rope-per-buffer rewrite:
the active buffer keeps its fields inline on `Editor`, inactive buffers park in a
small LRU `Vec<Buffer>` (≤ 3 resident = active + 2), and a switch marshals fields
in/out so the ~3k-line editing engine is untouched. A dirty parked buffer is
saved before it is evicted (nothing leaves RAM unsaved); `:e <path>` opens by
prefix (`/sd/repo` → Tracked, `/sd/local` → Local); `:sync` is refused in-core in
a Local buffer. Firmware drains the queue **to empty** each batch (a `Load` can
cascade an eviction `Save`), and `persistence::{load_path,save_path}` generalise
the atomic save off the hard-coded `notes.md`. 93 editor tests pass; the default
(no-git) firmware binary builds clean. Remaining v0.5 slices: 2 palette + fuzzy +
transient panel, 3 `:enew` + delete, 4 prefs + palette command mode.

- [ ] `Ctrl-P` opens fuzzy file palette over **both** `/sd/repo/` and
      `/sd/local/`, with a scope marker (e.g. `[git]` / `[local]`) per result
- [~] Open, switch, close buffers (keep ≤ 3 in memory) — **open + switch + the
      ≤ 3 LRU-resident model with dirty-aware save-before-evict done in core**
      (host-tested); `:e <path>` drives it today. Explicit **close** (and the
      palette that surfaces switching) still to come.
- [~] `:e` and palette share the same recent-files list — **`:e <path>` landed**
      (prefix → scope); the shared recent-files list arrives with the palette.
- [ ] `:enew` creates a new file — prompts for scope (tracked vs local)
- [ ] Delete a file — removes it from the SD card; for a Tracked file the
      removal reaches the next `Ctrl-G` Publish's staged set (`git rm` / `add -A`
      semantics, not plain `git add .`); a Local file is just unlinked
- [~] `Ctrl-G` is disabled / hidden when the current buffer is local-scope —
      **`:sync` / Publish is blocked in-core for a Local buffer** (posts "Publish
      unavailable (Local)"); the side-panel affordance that hides/greys the
      gesture is the remaining half.
- [ ] The side panel briefly shows file count on `Ctrl-G` when the publish bundles
      more than one dirty Tracked file (e.g. `"publishing 3 files: abc1234"`),
      so workspace-scoped behaviour stays visible to the user
- [ ] **Preferences file** `/sd/repo/.typoena.toml` — a git-tracked,
      hand-editable TOML file for editor behaviour, deliberately **distinct from
      the `/sd/typoena.conf` card secrets** (Wi-Fi / PAT / remote / author,
      gitignored, never committed — see v0.1). Read at boot; a missing file or
      key falls back to the defaults below. Keys:
  - [ ] `save_on_idle` (bool, default `true`) — auto-save the current buffer on
        the existing idle pause (the ≥ 1 s typing-pause the panel already uses
        for its refresh), so `:w` becomes optional rather than required.
  - [ ] `format_on_save` (bool, default `true`) — run `:fmt` (table alignment,
        blank-line collapse, trailing-whitespace strip) on the buffer before it
        is persisted, so `:sync` is **fmt → save → commit → push** and `:w`
        saves formatted. Implemented in-core 2026-07-11 (`Editor::format_on_save`,
        default on); this key will drive it. **Open question:** with
        `save_on_idle` also on, this reformats on every idle pause — reflowing
        tables / collapsing blanks mid-session. Consider limiting fmt to
        explicit `:w`/`:sync` and leaving the idle auto-save unformatted.
  - [ ] `line_numbers` (bool, default `true`) — show the absolute line-number
        gutter (built always-on in v0.2). Off reclaims the gutter's columns for
        text; the palette `> line numbers: on/off` command toggles it live.
  - [ ] `auto_sync` (duration string, default `"10m"`; `"0"` / omitted
        disables; **min clamp ~`"2m"`** so a palette typo can't drain the
        battery) — a *max-staleness cap*, not a wall-clock timer:
        **opportunistic, rate-limited** Publish. Push when already awake + dirty
        (coalesced into the idle-pause, ≤ once per `auto_sync`) and once on the
        way into sleep if dirty; **never wake from deep sleep purely to sync**.
        Wi-Fi energy is a `1/T` curve whose knee sits at 5–10 min, and
        `save_on_idle` already owns local data safety — so 10 min halves the
        sync energy of a 5-min default for no real risk. Full derivation:
        [`tradeoff-curves/wifi-auto-sync.md`](tradeoff-curves/wifi-auto-sync.md).
        The **schema + defaults live here in v0.5**; the periodic side rides the
        better-git work (v0.7) and must interact with light / deep sleep (v0.8).
  - [ ] Open question: because the file is committed, these prefs **sync to
        every device** that clones the repo — a per-device sync cadence may
        instead want a card-local override (in `typoena.conf`). Decide before
        build.
- [ ] **Palette command mode** — typing `>` at the `Ctrl-P` palette switches it
      from file search to a command list (VS Code-style). The v0.5 commands edit
      the `.typoena.toml` prefs above — e.g. `> save on idle: on/off` and
      `> auto sync: 10m` — writing the value back to the file and applying it
      live. This command list is the discoverable surface that later actions
      (`:fmt`, theme, font) also register into.

## v0.6 — Markdown affordances — [~]

**Status:** render affordances done early; the 80-col ruler and the snippet
engine remain (snippets are net-new scope, added 2026-07-08).

- [x] Heading lines bolded in render (faux-bold double-strike)
- [x] List continuation on Enter inside `- ` / `1. ` (with empty-item exit)
- [x] Soft-wrap at word boundaries
- [ ] Optional column ruler at 80
- [ ] **Snippets** — trigger-driven text expansion for Markdown authoring
      (Zed-inspired, but no completion popup: e-ink's ~630 ms refresh rules out
      a live filtering menu, and it fights the distraction-free premise). Shape,
      mirroring the existing `list_marker` insert-transform:
  - [ ] Tab in Insert mode triggers expansion: if the word immediately before
        the caret matches a snippet prefix, expand it; otherwise insert spaces
        as today (`expand_snippet(word) -> Option<(body, stops)>`, alongside
        `list_marker`).
  - [ ] A snippet body is literal text plus numbered empty tab stops `$1 … $n`
        and a final `$0`. There is no placeholder text (`${1:label}`) — the
        editor has no selection/overtype model, so a placeholder would just be
        text to delete. There are no dynamic or computed values either (e.g. no
        `date` — there's no RTC; the wall clock is valid only after Wi-Fi+SNTP,
        so it'd stamp 1970 on a cold boot).
  - [ ] After expansion the caret lands on `$1`; Tab advances to the next stop,
        forward only (no Shift-Tab). Stored stop offsets shift with edits at the
        caret (all pending stops are always after it). The session auto-aborts
        on Esc, a mode change, or a motion that leaves the stops.
  - [ ] On a typing pause (same throttle as the insert cursor / word-count
        refresh — the panel never repaints per keystroke), if the word before
        the caret is a snippet prefix, the side panel shows the hint (the target
        expansion). Quiet while typing; the hint appears on pause.
  - [ ] The snippet table is hard-coded in the binary to start; a git-syncable
        file on SD (`/sd/repo/.snippets`) is a later option, deferred while SD
        is still blocked.
  - [ ] Starter set: link `[$1]($2)$0`, image `![$1]($2)$0`, fenced code block,
        etc.

## v0.7 — Search + better git — [~]

**Status:** the **`:gl` pull command landed in the editor** (2026-07-11,
host-tested) — `Effect::Pull` + a firmware stub; the on-device fetch +
fast-forward is still to build. Search not started.

- [ ] `/` forward search, `n N`
- [~] `:gl` — pull: fetch + **fast-forward only**, refuse on divergence and
      surface it (renamed from the planned `:Gpull`). Editor command +
      `Effect::Pull` done 2026-07-11 (host-tested); the git-thread
      fetch/fast-forward in `git_sync` remains (only push is wired today).

## v0.8 — Power: battery + sleep — [ ]

- [ ] Measure idle / typing / push current draw on bench
- [ ] 18650 + IP5306 charge board, soft power switch
- [ ] Light sleep on idle > 30 s (keyboard interrupt wakes)
- [ ] Deep sleep on lid close (reed switch); restore cursor + buffer
- [ ] Battery indicator in the side panel

## v0.9 — Robustness — [ ]

- [ ] Crash-safe writes (write to `.tmp`, fsync, rename)
- [ ] Recover from interrupted push (re-attempt on next save)
- [ ] SD card removal / reinsert handling
- [ ] Wi-Fi reconnect with backoff
- [ ] On-device provisioning + settings screen: SSID, PAT rotation, default
      remote, commit author (replaces the v0.1 dev-only NVS-flashing path —
      first release usable by someone who is not the firmware author)

## v1.0 — Polish — [ ]

- [ ] Boot time ≤ 3 s to usable cursor — currently ~4.26 s; the ~1.9 s cold-boot
      full refresh is a hard e-ink floor, so ≤ 3 s is marginal (see
      [`notes/boot-time-budget.md`](notes/boot-time-budget.md))
- [ ] Font selection (at least one serif + one mono) with adjustable font
      size, switchable at runtime and persisted across reboots
- [ ] Theme: light / dark (inverted e-ink), switchable at runtime and
      persisted across reboots
- [ ] Enclosure design files in `hardware/`
- [ ] User guide

## v1.x — Stretch / nice-to-have

- 10.3" panel upgrade via IT8951
- Multiple remotes / repos
- Stats: words today, streak
- BLE-HID fallback for wireless keyboards
