FRICTION:
- tool | faketime x0.01 slowed a 600 ms Node timer to roughly a minute; normal advancing clock with monotonic bypass worked | publish the known-working normal-speed libfaketime recipe.
- tool | Preview evaluate rejects leading/trailing expression whitespace | trim driver expressions before calls.
- tool | A custom WebSocket subscription stalled after its initial chunk until the driver ACKed chunks | document the RPC streaming ACK contract beside protocol examples.
- tool | agent-device delta references require their full pinned suffix; an unpinned stale reference was rejected | use the exact returned reference or refresh the snapshot.
- tool | Pairing a native deep link while its Metro bundle was still loading lost the route; retry after the app was ready succeeded | await app readiness before pairing.
- brief | The matrix calls four affected rows optional/equivalent while the round-2 brief requires every affected row | make the stricter round's scope explicit in the matrix handoff.
- tool | The mock catalog exposed Default or Auto for the same default model slug, making a later W3 recapture differ outside the error text | use an explicit stable Composer 2 selector on both failed threads without sending a new turn.
- tool | Native cellular signal glyphs changed between otherwise stable screenshots | use airplane mode with Wi-Fi retained before final captures and compare OS chrome too.
- tool | Remote device daemon briefly timed out after airplane/Wi-Fi changes; a retry after a minute recovered the same session | wait for transport recovery after network configuration changes.
- tool | Metro CDP rejected a direct WebSocket without the matching Origin header (401), and helper discovery stalled after relaunch | send the Metro origin explicitly; native-clock.mjs records the working fallback.
- infra | Egress recovered long enough to upload the W1 desktop sheet and determinism JSON, then DNS stopped resolving the ghdrop host; three later POST attempts failed and direct HTTPS probes timed out | keep VM DNS/egress stable for artifact publication.
