 ### M8: REPL + Interactive Forth
 
-**Goal:** Type Forth at the kernel, get `ok` prompt
+**Status:** Scoped 2026-08-11 (this section). Substrate (interrupt-driven keyboard
+input, glyph rendering) already complete via Stadium's Console fabric work
+(FABRIC.md §25.5 items 4.3.5–4.3.7f) — see "What's already done" below. This
+scoping pass covers what's left: wiring the existing keyboard-event stream into
+the REPL's character input path.
+
+**Goal:** Type Forth at the kernel *keyboard* (not just serial), get `ok` prompt.
+The REPL already works interactively over serial today (`sk_repl_run()`,
+`src/starkernel/repl.c`) — that is not what this milestone adds. What's missing
+is a second input source feeding the same loop.
+
+**What's already done, read from the code before scoping this, not assumed:**
+- Interrupt-driven keyboard input on all three architectures (amd64 i8042,
+  aarch64/riscv64 virtio-keyboard-pci + GIC/PLIC), converged behind one shared
+  interface: `KEY-EVENT ( -- keycode pressed -1 | 0 )` in
+  `src/word_source/keyboard_words.c`, `keycode` in the Linux input keycode
+  namespace. FABRIC.md items 4.3.5–4.3.5f, verified live on all three
+  architectures with real keypresses.
+- Glyph rendering, both paths: the stroke-drawn font (`TEXT`, capsule-based,
+  113-glyph v1 repertoire, FABRIC.md 4.3.6–4.3.6g) and TrueType (`TTF-TEXT`,
+  proportional spacing via real `hmtx` advance widths, FABRIC.md 4.3.7–4.3.7f).
+  Neither is required for the REPL text itself, though — see the VT100 finding
+  below.
+- **The REPL's on-screen text already renders independently of both of the
+  above.** `console_fb_init()` (`src/starkernel/hal/console.c`) calls
+  `vt100_init()`, which mirrors every `console_putc()`/`console_puts()` call to
+  the framebuffer via the baked-in `font_8x16.c` raster font. This is *already
+  live* — the REPL prompt and its output appear on screen today, serial-driven,
+  no CANVAS/glyph-capsule dependency. This confirms §27.6's mockup: a fixed
+  VT100 REPL strip (already working) plus a separate large CANVAS region above
+  it (still unsized — see the last deliverable below).
+
+**What's actually missing, confirmed by reading the code, not assumed:**
+`src/starkernel/repl.c`'s `sk_readline()` reads characters via
+`console_getc()` (`src/starkernel/hal/console.c`), which is serial-UART-only —
+it never looks at `KEY-EVENT`. Separately, the FORTH-79 words `KEY`/`?TERMINAL`
+(`src/word_source/io_words.c:84-108`, shared/vendored source) are dead in the
+kernel build: `KEY` calls libc `getchar()`, which the kernel shim
+(`src/starkernel/vm/host/shim.c:1206`) hardcodes to return `-1` (EOF);
+`?TERMINAL` is a literal stub that always returns false. Neither path has ever
+been wired to a real keyboard.
 
 **Deliverables:**
-- [ ] Keyboard input (PS/2 or USB HID)
-- [ ] REPL loop integration
-- [ ] Line editing (backspace, minimal)
-- [ ] Word execution from console
+- [ ] Minimal scancode→ASCII layout: a small lookup table (US QWERTY,
+      unshifted/shifted rows only — no dead keys, no locale switching) driven
+      by `KEY-EVENT`'s Linux-namespace keycodes, plus shift-state tracking
+      (`KEY_LEFTSHIFT`/`KEY_RIGHTSHIFT` press/release) since `KEY-EVENT` itself
+      carries no modifier state today (confirmed by reading
+      `keyboard_words.c` — deferred at 4.3.5f, not implemented anywhere).
+- [ ] Merge keyboard into `console_getc()`'s poll: extend it (or add a second
+      function `sk_readline()` polls alongside it) to also drain `KEY-EVENT`
+      and translate presses to ASCII via the layout table above. **Serial stays
+      a co-equal input source, not replaced** — the entire acceptance/DoE
+      harness injects FORTH commands over the serial socket
+      (`socat ... UNIX-CONNECT:$SERIAL_SOCK`) and greps the serial log for
+      `ok>`; breaking that path breaks `make qemu`, `DOE_INJECT`, and every
+      screendump verification technique used throughout 4.3.x. Both sources
+      feed the same byte stream into the existing `sk_readline()` — no new
+      line-editing code needed, backspace/echo already work
+      (`sk_readline()`, `repl.c:83-141`).
+- [ ] Wire `KEY`/`?TERMINAL` (`io_words.c`) to the same merged source under
+      `#ifdef __STARKERNEL__`, for FORTH-79 compliance — any capsule calling
+      these directly (not just the REPL) should get real input too, not a
+      permanently-EOF stub. Small addition once the merge above exists.
+- [ ] CANVAS viewport sizing (§27.6's explicit deferral to this milestone): the
+      large graphics region above the VT100 REPL strip needs an actual
+      scrollable framebuffer viewport size decided (e.g. 640×480, per the
+      original mockup) — layout/presentation, not input plumbing; do this
+      last, after keyboard input works, since it doesn't block interactivity.
+
+**Explicitly out of scope for this milestone (minimal bar, matches "Line
+editing (backspace, minimal)"):** extended (`0xE0`-prefixed) i8042 scancodes,
+virtio-input autorepeat (`value=2`) as actual character repeat, arrow-key
+cursor movement/history, non-US keyboard layouts. Deferred to a later item if
+ever needed — not blocking "type Forth at the kernel, get `ok`."
