You are not making sense to me either.
What absolute evidence is there to prove that Samaales are only 800 years old? No written evidence to support such a claim.
What absolute evidence is there to prove Aw Barkhadle lived in the 12-13th century? No written evidence whatsoever but just theories.
Abtirsi is not a reliable historical source to determine the age of the Samaale ethnic group as it could be subjected to falsification, omission or expansion of ancestors etc.
I never argued that the ancestor of certain Somali haplogroup T carriers lived a 1000 years ago. Previously, I stated that the TMRCA of the Somali Haplogroup T cluster that I belong to is estimated to be around 2000 years old in the Danish study. Anyway, what has this got to do with my dismissal of unproven theories as to what route my haplogroup T ancestors took when they settled the Horn.
The authors of the Danish study were aware they had a limited and undefined gene pool. How can you accept that and still complain about unknown subclans in the other data? Your dismissal of "unproven theories" is your business. But I believe we have enough to conclude T came from the north.
Whether they came through Sinai or the Red Sea is immaterial at this point. That will come out with further testing. The important issue is that there is too much T in the Dir for them to have been part of the E1b1b migration. They did not come from the south.
Lacking written material, we have to turn to less explicit techniques, such as archaeology. So far, we have Aksumite/Himyarite/Harla settlements in the North, and an Ethio-Arabic rock art site at Laas Gaal. In the South we have Buur Heybe, an 11,000 year old site linked to the Eyle, a definitely indigenous people of Negroid/Khoisan.descent. Perhaps you can also work from that direction.
I find this chronology helpfull:

As’ad al-Himyari rules Mogadishu and environs.
632 AD The exiles of the Riddah (apostasy wars), mainly from Oman,

of Juland to settle on the East African Zanj coast.

Muruj al-Dhhahab wa Ma’adin al-Jawhar
(The garden of gold and gems), describes the socioeconomic life of Somali cities,
both on the Khalij al-Barbari (Gulf of Aden) and the Bahr al-Zanj
(Indian Ocean).
1000 Hassan ibn Ali al-Shirazi leads the largest migration from Persia
to East Africa.
1001 Oligarchic city governments emerge in Mogadishu and coastal
towns of southern Somalia. Mogadishu is governed by a con-
federation of 39 clans: 12 from the Muqri clan, 12 from the
Djid’ati, 6 from the Aqabi, 6 from the Isma’ili and 3 from
the Afifi.
1154 Al-Idrisi (1100–1166), a Muslim geographer, reports that Marka
(Merca) and Barawat (Barawa) are towns on Bahr al-Zanj (the
Sea of the Blacks), that is, the Indian Ocean, and that there are
Hawiye settlements on the Banadir coast.
1228 Al-Hamawi (d. 1228), a Muslim traveler who compiled
Mu’jam al-Buldan (Dictionary of cities), includes entries for Zayla,
Berbera, Mogadishu, and Marka. He notes that the inhabitants of
Berbera are very dark and speak an unwritten language, but that
the inhabitants of Mogadishu are not blacks.

1499 3 January: Vasco da Gama shells Mogadishu, “a large town,
with houses of several stories, big palaces in its center, and four
towers around it.”
Do you notice all the "protos" in the first part, and all the potential T in the last? The Somalis, as Somalis, form quite late. E1b1b and T are both far older, but at that age they are neither Samaale nor Somali. The first mention of a Samaale clan is likely the one by Al-Idrisi in 1154. But even that is less than 1000 years ago, and I don't think you will find an abtirsi that old.
