+  `./scripts/ws_protocol_client.py 192.168.1.50 --verify-m010 --stress-moves 80
+  --repeat-matches 2` against the target device. It passed six-client load with
+  four complete observers, six-client responsiveness (86.9 ms), slow/malformed
+  stress (455.4 ms maximum player latency and 387 dropped latest observer
+  updates), and two repeated match cycles (16-byte heap range). Final
+  diagnostics recorded active connections 2, connection high-water 6, queue
+  high-water 8, queue depth 0, 202,292-byte minimum internal free heap,
+  184,320-byte minimum largest block, 20 malformed messages, 21 rate-limited
+  messages, 80 accepted commands, two completed/reset matches, and no PSRAM
+  requirement. The subsequent `/health` response was `serving` for version
+  `0.10.0`. Acceptance criteria 1--4 and 6 now have concrete evidence;
+  physical station/fallback provisioning and browser-recovery evidence for
+  criterion 5 remains pending, so Milestone 010 is `IN_PROGRESS`.
+- On 2026-09-08, `./scripts/run_host_tests.sh` passed every health, Wi-Fi
+  configuration, NVS, provisioning, lobby/protocol, maze, game, disconnect
+  recovery, browser, and web-asset suite. Its deterministic maze sweep covered
+  1,024 seeds and its repeated-match reset test completed 128 cycles. The
+  owner also ran `pio run -e esp32-c6-devkitm-1`, which passed with 124,276 of
+  327,680 RAM bytes and 1,028,956 of 2,097,152 application bytes, and
+  `pio run -e esp32-c6-devkitm-1 --target buildfs`, which passed with the
+  2,031,616-byte LittleFS image exactly fitting its 2,031,616-byte partition.
+- On 2026-09-08, the owner confirmed physical station recovery after network
+  disruption. `/api/wifi/status` returned
+  `{"state":"station_connected","accessPointSsid":"maze32-F7B9",`
+  `"ip":"192.168.1.50"}`, and bounded station retries behaved as expected.
+  The owner also confirmed the fallback provisioning page worked as expected
+  and that both active player sessions restored their original slots through
+  saved tokens. Together with the successful target stress run, host
+  regressions, production builds, and fixed-limit evidence above, this
+  satisfies every Milestone 010 acceptance criterion. Milestone 010 is
+  `COMPLETE`; Milestone 011 remains `NOT_STARTED`.

 ### Evidence
 
-Completion evidence is not yet available because this milestone has not
-started. Required evidence includes playtest data, the mapped acceptance report,
-final build hashes and sizes, and project-owner approval of any deviations.
+Implementation is in progress. `docs/BALANCE_REPORT.md` locks the current MVP
+gameplay configuration and records the deterministic maze metrics. The
+playtest procedure and result table are in `docs/PLAYTEST_REPORT.md`, and the
+criterion-by-criterion evidence register is in `docs/MVP_ACCEPTANCE.md`.
+Representative completed-match timings and the final release build record are
+still required before this milestone can be marked `COMPLETE`.
+- On 2026-09-08, `bash scripts/run_host_tests.sh` passed its health, Wi-Fi,
+  NVS, provisioning, lobby/protocol, maze, game, disconnect-recovery, browser,
+  and web-asset suites. The locked 1,024-seed sweep reported cycles `133..133`,
+  dead ends `704..854`, start-to-key distance `416..1442`, and key-to-exit
+  distance `346..1244`; every generated map satisfied the key-distance balance
+  invariant. `pio run -e esp32-c6-devkitm-1` passed using 124,276 of 327,680
+  RAM bytes and 1,028,956 of 2,097,152 application bytes. The matching

+  `docs/MVP_ACCEPTANCE.md` records version `0.10.0`, build hashes, and the
+  19,253-byte reproducible web payload. Human playtest evidence for the
+  approximately five-minute target remains pending, so Milestone 011 is
+  `IN_PROGRESS` and Milestone 012 has not started.
