 ### Evidence
 
-Not started. This milestone records the project owner's 2026-09-09 decisions:
-the child drags the centered player icon; the icon deflects slightly as the
-control handle while the authoritative map moves below it; displacement controls
-speed; approximately 100 ms is ideal, 150 ms is acceptable, and delays near
-500 ms are unacceptable. Implementation must wait for Milestone 016 to identify
-and prioritize the actual latency contributors.
+Implementation and automated validation are in progress. This milestone records
+the project owner's 2026-09-09 decisions: the child drags the centered player
+icon; the icon deflects slightly as the control handle while the authoritative
+map moves below it; displacement controls speed; approximately 100 ms is ideal,
+150 ms is acceptable, and delays near 500 ms are unacceptable.
+
+- On 2026-09-09, the browser control was changed from a separate joystick to a
+  96 by 96 CSS-pixel transparent target around the centered avatar. The visible
+  avatar deflects at most 28 CSS pixels, uses a 12-pixel dead zone and diagonal
+  hysteresis, and schedules cardinal repeats from 360 ms to 170 ms. It resets
+  on release, cancellation, lost pointer capture, pause, disconnect, blur, and
+  hidden-document events. `LatestIntentFlow` keeps one sent move in flight and
+  retains at most one replacement intention; release discards the replacement.
+  The map continues to render only complete server-authoritative projections.
+- On 2026-09-09, `node --test test/web/test_player_app.js` passed all 17 tests,
+  including avatar bounds, cadence, direction hysteresis, latest-intent
+  coalescing, reset paths, authoritative projections, keyboard/swipe
+  alternatives, observer immutability, and bounded diagnostics. `bash
+  scripts/run_host_tests.sh` passed all host tests and deterministic web-asset
+  verification (`2ca96e65b3aa06385028c420c7e605b2e422f7d0c57cae2d81e277a53ecdf6b3`,
+  25,121 of 1,572,864 allowed compressed bytes).
+- On 2026-09-09, `/home/sasa/.platformio/penv/bin/pio run -e
+  esp32-c6-devkitm-1` passed with 58,868 of 327,680 RAM bytes and 1,027,966 of
+  2,097,152 application bytes. `/home/sasa/.platformio/penv/bin/pio run -e
+  esp32-c6-devkitm-1 --target buildfs` passed and reported a fixed LittleFS
+  image of 2,031,616 of 2,031,616 bytes.
+- `docs/M017_LATENCY_REPORT.md` records the M016 baseline, the browser backlog
+  remediation, the required isolated-LAN deployment setup, and the controlled
+  before-and-after retest procedure. The physical mobile usability observation,
+  isolated-network 200-sample runs, and maximum-session diagnostics are still
+  required for acceptance criteria 6, 7, 9, and 10. Milestone 017 remains
+  `IN_PROGRESS`; Milestone 018 has not been started.

-# Maze32 command chamber
-
-This package designs a 12 m × 12 m gameplay-room lobby with a single central
-hero: the maze command table. Four stations give players a clear color-coded
-place around a protected circulation ring. The open north portal is 3 m wide
-and exposes a short arrival apron rather than implying a blocked route.
-
-All final geometry is procedural Blender geometry: slabs, walls, column rhythm,
-hero table, stations, ceiling beacon, and lighting. No external mesh or paid
-generation is needed. `build_command_chamber.py` uses an Exact Boolean for the
-north opening before adding the brass surround.
-
-Run it with a Blender installation:
-
-```sh
-blender --background --python build_command_chamber.py -- --output maze32-command-chamber.blend --renders renders
-```
-
-The package is deliberately at the Function-review stage. The prop image and
-opening schedule have **not** been marked approved, and no form or runtime
-approval has been claimed. After a reviewer inspects the production and review
-renders, record their explicit decision in `milestone-reviews.json`; then run
-the skill validator for the relevant gate.

+# Milestone 017 latency remediation report
+
+## Baseline
+
+Milestone 016 recorded an unsuitable local Wi-Fi tail: 100 HTTP requests had
+7.5 ms minimum, 186.7 ms average, 508.0 ms p95, 713.3 ms p99, and 985.4 ms
+maximum round-trip time. The available browser samples ranged from 19 to 548
+ms for command acknowledgement and from 30 to 551 ms for an authoritative
+painted view. ESP handler and send measurements were materially smaller during
+the partial runs. The M016 project-owner-approved deviation records that the
+remaining controlled runs could not be completed on that path.
+
+## Browser remediation
+
+The player now uses the centered avatar as a 96 by 96 CSS-pixel transparent
+touch target. Pointer movement changes only a local avatar deflection capped at
+28 CSS pixels. A 12-pixel dead zone, diagonal hysteresis, and a 360-to-170 ms
+monotonic cadence resolve a cardinal movement intention without exceeding the
+150 ms server cooldown.
+
+The browser sends at most one move at a time. While that command awaits an
+acknowledgement or error, changing drag direction replaces one local latest
+intention. Release removes the unsent intention. Consequently a slow socket
+cannot accumulate a client-side movement backlog. No browser code predicts a
+maze position, collision result, inventory, visibility, timer, or outcome.
+
+## Required deployment-network remediation and retest
+
+Do not use the M016 Wi-Fi path for latency acceptance. Place the ESP and both
+test clients on the same dedicated 5 GHz access point or the ESP fallback AP,
+with no WAN routing, captive portal, VPN, power-saving transition, or active
+bulk traffic. Record access-point model/band/channel, client hardware,
+browser/version, RSSI, device address, build identity, and viewport.
+
+Repeat the M016 procedure for two players with zero observers and with four
+observers. For each player, collect at least 200 accepted moves and export:
+
+```js
+window.maze32PlayerApp.pointerFeedbackSamples()
+window.maze32PlayerApp.latencySamples()
+```
+
+Record p50, p95, p99, and maximum values separately for pointer feedback,
+command acknowledgement, complete authoritative view, and painted
+authoritative view. Capture `/diagnostics` before and after each run and 100
+ICMP plus application/WebSocket round trips. The acceptance target remains
+painted-update p95 at or below 100 ms, maximum at or below 150 ms, and no
+accepted sample at or above 500 ms. Do not mark this report as a passing
+device measurement until those controlled results exist.

+The centered player avatar is also the touch movement handle. Its transparent
