with the ERC and DRC results from python3 scripts/check_pcb.py; list each
remaining violation and its reason, or state that none remain.
Review comments at @openspec/changes/push-button-extension/design.md:
- Line 62: Update the push-button requirement associated with POST /play to
state the supported edge-queue limit and what happens on overflow; bound the
press-and-release guarantee to clicks whose two edges are retained, rather than
promising it unconditionally.
- Line 47: Update pushButtonPoll() to suppress the initial release when the
button was held at enable time, then arm event publication so only subsequent
button transitions, including the next press, can publish events; preserve the
existing debounce behavior.

- Around line 90-91: Update the “CLI watch over HTTP uses the event socket”
requirement to define HTTPS handling: use a reachable TLS-protected WSS
endpoint, or explicitly reject HTTPS URLs. Ensure HTTPS never falls back to
plaintext ws, especially when appending a Bearer token.

Review comments at @packages/tiny-engineer-cli/src/commands/watch.js:
- Line 118: Update the WebSocket construction in the watch flow to set a short
handshakeTimeout, so a connection that never completes the upgrade triggers the
existing error handler and exits instead of waiting indefinitely.
- Around line 117-146: Update the WebSocket error and close handlers so failures
after the socket opens set process.exitCode to 1, while preserving the existing
failure behavior for pre-open errors and closes. Keep Ctrl+C as a deliberate
interruption rather than treating it as a failed disconnect.
Review comments at @src/events/hub.cpp:
- Around line 72-93: Add a hub function to disconnect all current WebSocket
subscribers, using a disconnect-all overload supported by the WebSocket server,
and call it from handleSettingsPost only when access_token changes to a
non-empty value. Leave token clearing behavior unchanged; locate the hub
implementation near onWsEvent and tokenOk.
Review comments at @ui/src/App.tsx:
- Line 49: Register `/extensions` in `kRoutes` with `handleIndex` as its handler
so direct requests in configured mode serve the UI instead of reaching
`handleNotFound`.

* Updated API documentation to clarify that setting or rotating a non-empty access token will disconnect current WebSocket subscribers, requiring them to reconnect with the new token. * Implemented a new function to disconnect all WebSocket clients upon access token rotation. * Modified settings handler to invoke the disconnection function when the access token is changed.

🟠 Major · Percent-decode the token query value in tokenOk before comparing it. · hub.cpp:50-60
src/events/hub.cpp:50-60
🔒 Security & Privacy | 🟠 Major | ⚡ Quick winPercent-decode the
tokenquery value intokenOkbefore comparing it.The CLI builds the watch URL with
ws.searchParams.set("token", token). This encodes reserved characters in the token. For example,%becomes%25,&becomes%26,+becomes%2B, and=becomes%3D.tokenOkcompares the raw query bytes with the configured token and does not decode them. A configured token that contains any of these characters therefore never matches. The authenticated/eventsconnection is then disconnected.Decoding the
tokenvalue intokenOkmakes the firmware match the encoded URL. The CLI encoding stays unchanged.Suggested fix
Percent-decode the value in
tokenOkbefore thememcmp. Decode into a fixed buffer sized to the 64-character token limit, and reject values that exceed it.🤖 Prompt for AI Agents

The robot only took commands. A button on the Extension port could not drive host-side automation until the device could push events out. This PR adds that outbound path, a configurable push-button extension (edges + gestures + optional local SFX), CLI
