Highlights

Hardening

  • The run session now notices Ctrl-C/SIGTERM while idle: a signal landing in the gap before its input read blocks (or delivered on another thread) previously left the session waiting for the next command line; a self-pipe wake-up closes the window.
  • The QEMU child's serial capture keeps a bounded 1 MiB tail instead of growing for as long as a serve session runs; expect regexes and failure diagnostics only ever read recent output.
  • Boot failures for a missing emulator binary name the offending path on both macOS and Linux.
  • The fixture build image is pinned by digest, so an upstream re-tag cannot silently change fixture bytes and golden stability.

Docs

  • New README section: What each backend is authoritative for - a fidelity matrix across host-native, QEMU tier 1 (any flash image), and QEMU tier 2 (cooperating firmware), including per-architecture determinism (ESP32-C3 byte-exact under icount; ESP32/S3 wall-clock).

Binaries below carry the generic native targets plus both qemu board specs; the waveshare_amoled_18 target needs a source build against a firmware checkout (see README). esprite is alpha software; interfaces may change.
