…re C3 labs The Playground has no prod compiler, so a shared/agent lab only runs from a pre-built binary. Bare esp32c3-supermini labs had none, so every C3 lab opened from the hosted MCP died with "Cannot run: no firmware". This adds the canonical GPIO8 blink example whose committed ELF the Playground can fall back to (app-side wiring lands separately). Drives the plain R/W GPIO_OUT/GPIO_ENABLE registers (silicon-valid) because the C3 gpio block is the declarative register file without W1TS/W1TC side effects. The e2e test also pins rv32 C.JAL decoding: the blinky is small enough that the linker emits a compressed jal from _start to main. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Why
Hosted MCP / shared Playground labs only run from a pre-built binary (prod has no compiler). Bare
esp32c3-superminilabs had none, so every C3 lab opened from ChatGPT died with "Cannot run ESP32-C3 Super Mini: no firmware".What
examples/esp32c3-blinky: bare-metal rv32imc GPIO8 (user LED) blink with UART narration, reusing the Leo example'sstartup.S/c3.ld/c3_uart. Committed ELF so no toolchain is needed to consume it.GPIO_OUT/GPIO_ENABLEregisters (silicon-valid) because the C3 gpio block is the declarative register file without W1TS/W1TC side effects.test-blink.yamlscenario +e2e_esp32c3_blinky.rs: asserts boot banner, several LED ON/OFF transitions, andGPIO_ENABLEbit 8. Also pins rv32 C.JAL decoding — the blinky is small enough that the linker emits a compressedjalfrom_starttomain(the pre-esp32c3: RISC-V rom-boot + RV32C decode fixes + WiFi MAC RE #254 decoder bug class would send it into unmapped flash; none of the existing examples exercise it).Verification
