If all criteria pass, set this milestone to `DONE`, append its execution record, and change Milestone 009 from `BLOCKED` to `READY`.
### Execution record
- Date: 2026-08-28
- Board model and revision: ESP32-C6FH4 QFN32, revision v0.2.
- Toolchain and library versions: PlatformIO Core 6.1.19; `espressif32` 7.0.1; ESP-IDF 6.0.1; `esp_littlefs` 1.20.4.
- Result: PASS.
- Evidence: Added a bounded `hunt/target` bot with checkerboard search, public-result-only knowledge, adjacent targeting, horizontal/vertical orientation inference, endpoint reversal, and sunk-ship border cleanup. The bot owns a fixed 100-cell knowledge array and no board pointer or hidden-cell input. Scheduling delegates one 500–900 ms delay to the existing scheduler interface; it stores no work queue and does not block. Cancellation clears a pending bot turn.
- Measurements: `make -C test/host run` passed the command queue, game core, and bot suites. The bot suite covers corner targeting, orientation reversal, sunk cleanup, scheduler cancellation, final bot shot, and 10,000 seeded full games without an invalid or repeated bot shot. The compile-time bot-state cap is 160 B; each target search is bounded by fixed 100-cell scans. `pio run -e esp32-c6-devkitm-1` passed with 38,212 / 327,680 B RAM (11.7%) and 1,000,730 / 2,097,152 B flash (47.7%), within the Milestone 005 limits.
- Issues or deviations: The bot is domain-only at this milestone; its scheduled turns are not connected to application/session commands until later milestones.
- Next action: Milestone 009 is ready. Do not start it unless explicitly requested.
