Is it an artifact or do I see white smoke billowing from port side engine just around time of rotation?

trouble is we have no evidence of anything at all about the start-up, taxi, roll etc. No pax videos inside or outside the windows to disclose unusual noises, announcements or anything. Not yet.,

Seat movement cannot be discounted. There have been several such incidents affecting the 787

Is there an incident (or your experience in a sim session?) that you can refer to?

Surprising that you can do nearly a minute of takeoff+climbout then fail cleanly and silently within seconds of each other.
I would, of course, presume, that take-off roll performance was within expected limits, otherwise they would have aborted by V1. They reached VR before running totally out of runway, and achieved a short-lasting climb. What one single point of failure occurred very shortly after aircraft went nose-up and would it be possible that the fuel feed in some way affected by virtue of that angle in the context of some failure?

3 possibilities come to mind:

1. Pilot who moved fuel switches to off did not do so intentionally to cause the outcome, but for some reason unknown (extreme fatigue, medical condition, medication/drug) somehow confused the action of retracting gear with shutdown procedure at end of flight.

2. Unthinkably, but very possibly, pilot who moved fuel switches did so intentionally, likely planned ahead of time to catch out other pilot at a moment where focus was intently on flying & recovery most unlikely. Mental illness, drug use, personal circumstances behind it.

3. Something extraordinary which was never encountered before which caused or allowed fuel switches to move on their own.

When both pilots flying & personal history is investigated, more is likely to emerge, maybe something to support possibility 1 above, where a pilot had on some previous occasions got sequences confused, or suffered brief episodes of seizures whee he took strange actions.

The CVR records one pilot asking \x93Why did you cut off?\x94, the other replies \x93I didn\x92t\x94. Then a bland Mayday attributed to the Captain \x93engine failure, returning\x94 in the middle of the crisis.

The language, if reported correctly, feels strangely detached. No confusion, no urgency, no clear troubleshooting. Not drawing conclusions, but does anyone else see signs of performative behaviour, that is saying the right things outwardly, while being at odds with the underlying cause?

I appreciate that both crew members lost their lives, however if we avoid discussing uncomfortable patterns, we miss the point of investigation and learning.
in that fraught moment of engines not functioning very close to the ground, the last thing to do at this critical moment when you don\x92t really known what has happened is communicate a MayDay. With the buildings looming up fast, the action required is to attempt to restart, as seems to have been done by a pilot putting the fuel switch to \x93run\x94, but too late to rescue aircraft. I think the timing of the MayDay call is strange given that the scenario called for Aviate, Navigate\x85 then Communicate.

In past occasions where pilots committed (or intended to) suicide/murder by means of a pax airliner there has sometimes been evidence of mental illness in the past - Germanwings which is in everyone\x92s living memory, and Japan waaay back when one of the pilots was found to have had some history of schizophrenia/psychosis; other times it\x92s been a case of personal issues (thought to be the case with Silk Air) like financial ruin where the pilot takes everyone else with him; whilst at least one other (Alaska) was due to a pilot having serious beef with the airline. None of it makes actual sense to most of us, especially taking others with you when not psychotic, but these factors will undoubtedly be explored to a full degree before the final report comes out. It must also be remembered that people can suffer unusual kinds of seizures, which may last very briefly, where intentional/complex movements are made, be it from neurological disorder or another medical condition/medication/drugs. However unlikely. The brain is a very complex thing which makes aviation technicalities seem simple.
