How significant is birth tithi in Jyotish compared with planetary placements and house strength?

I’ve read in BPHS, Chapter 87 that Krishna Chaturdashi is divided into six parts, with only the 1st part considered auspicious and the 6th considered the most inauspicious, associated with destruction of wealth and even harm to the native. However, no Jyotish I consulted has ever mentioned this in my chart, and I don’t believe any specific remedy such as Rudra Homa was performed.

How seriously should this BPHS rule be interpreted in actual chart analysis? Is it considered a major dosha that can override or significantly modify otherwise favorable planetary/house placements? And if applicable, are there any traditional remedies that can still be performed later in life?

How does a four-planet stellium of Sun, Moon, Mercury, and Venus in Libra in the 10th house affect career and public standing?

Placement details:

Stellium: Sun, Moon, Mercury, and Venus in Libra, 10th house.

Sun: Atmakaraka, 8th Lord, debilitated in Libra, gains Digbala in 10H, forms Neechabhanga Raja Yoga via Venus.

Questions:

How does the 8th Lord and Atmakaraka Sun manifest in the 10H under debilitation and NBRY?

How do Moon, Mercury, and Venus modify the Sun's debilitation and shape the overall professional trajectory?

I've been trying to understand the practical hierarchy between house → sign/dignity → Nakshatra → Nakshatra lord → conjunction/aspects.

For example, how should we think about:

• an exalted Mars in Capricorn but in Shravana (Moon-ruled)
• a debilitated Sun in Libra but in Vishakha (Jupiter-ruled)
• Saturn in Rohini (Moon-ruled)
• Jupiter in Punarvasu (own Nakshatra) while conjunct Rahu
• Rahu in Mrigashira (Mars-ruled)

In the debilitated Sun example especially, does being in a Jupiter-ruled Nakshatra meaningfully change how much the debilitation manifests, or does the Libra debilitation remain the primary factor? Or since Sun gets digbala being positioned in 10H with Venus,mer,moon has lesser debilitation effect?

Basically, I'm trying to understand whether Nakshatra is mainly a flavour/modifier of the planet, or whether a strong/weak Nakshatra lord can substantially alter the planet's sign-based dignity.
