Namaskaram Kalyan ji,
Taking the liberty to share couple of thoughts:
First and foremost, both bandha and moksha (exist only within the realm of vyavaharika. From the paramarthika standpoint, the Self is nitya-suddha-buddha-mukta-svarupa. Any quest to "attain" moksha or verify its attainment arises solely from the empirical viewpoint and is rendered irrelevant in the ultimate reality.
The crux of Advaita Vedanta is the recognition that the so-called attainment of moksha is akin to realizing the illusory nature of the earlier cognition of a snake on a rope. Just as one discovers the rope to be free of the snake, one realizes that (bandha-moksha) are themselves mithya. Verification, therefore, is confined to the recognition of the mithyatva of bondage and liberation themselves.
Having said so, getting to your questions:
<< How can moksha be verified externally and internally? Can it even be verified at all? >>
Expanding on your original question, we can consider the following points:
Q1: Is moksha or Self-realization achievable? If it isn't, then disciplines like brahma-vidya and moksha-shastra lose their significance.
Q2: If moksha is achievable, how can one recognize that they have attained it? Without such recognition, the achievement of moksha would be indistinguishable from not attaining it—this pertains to "internal verification."
Q3: Assuming internal verification is possible, how can others validate this attainment? Without external verification, any personal experience could be mistakenly or falsely identified as moksha—this relates to "external verification."
Answer to Q1: Whether moksha is attainable largely depends on our current beliefs. If one believes themselves to be a limited, individualized entity (referred to as 'bandha'), then attaining moksha becomes possible. This belief underpins the relevance and effectiveness of brahma-vidya and moksha-shastra.
Regarding Q2 and Q3: These questions are critically important. History has shown that many self-proclaimed gurus have mistakenly equated their extraordinary experiences or the methods to achieve them with moksha-jnana. Without proper indicators for both internal and external verification, individuals risk falling into such misconceptions.
<< Internal verification - How can X verify his or her own claim to moksha? >>
Certainly, an individual can internally confirm their attainment of moksha. A profound realization that bandha is mithya and does not require overcoming serves as evidence of achieving moksha.
Moksha-jnana—the knowledge of liberation—involves recognizing one's true essence as nitya suddha buddha mukta. This realization dissolves the sense of being a limited independent individualized self and eliminates desires, fears, and likes-dislikes related to worldly experiences. Such profound changes are distinctly identifiable and honestly recognizable within oneself. Such a person is a tattva-darshi jnani sthitha-prajna jivanmukta.
<< External verification - If some X makes a claim that he or she obtained moksha, how can others verify that claim? This means, a completely external person who could be a non-believer or from another religion or from another Darshana should be able to verify the claim of X. Is that possible? >>
Yes, it is possible to externally verify someone's claim of having attained moksha. However, the degree to which this verification can be achieved largely depends on the external person's understanding and knowledge of moksha. Fundamentally for an individual to verify an external claim, they must first possess the requisite knowledge about what is being verified. For instance, without understanding Malayalam, one cannot accurately assess the validity of a translation from English to Malayalam. However, a tattva-darshi jnani sthitha-prajna jivanmukta guru possesses the deep insight necessary to accurately identify and verify a student's internal realization of moksha. This underscores the critical importance of tattva-darshi jnani jivanmukta guru; guru-shishya parampara; proximity / satsangam / 'upanishad' or approach to a guru; and Bhagavan's reference to such a guru in SBG-4.34.
Question: How can an ordinary person, who has not yet realized the Self, verify another person's claim of attaining moksha?
Response: While it may not be possible to verify moksha claims with absolute certainty, there are indicators that can suggest such an attainment to a certain extent. Individuals can look for manifestations of qualities associated with a stitha-prajna, tattva-darshi, jnani as described in the Upanishads, SBG, and authoritative teachings of various sampradhaya acharyas. For instance, the insightful talk by Pujya Swami Ramanacharana Tirtha on 'Jivanmukta Lakshanam' offers valuable perspectives on identifying the signs of moksha -

Question: If the internal verification of moksha relies on an external guru's verification, doesn't this create an infinite regress? That is, each guru's claim would then require verification by a preceding guru, potentially leading to a never-ending chain where everyone fails to recognize true moksha attainment.
Response: This concern is addressed within traditional sampradhayams through established foundational principles. In all sampradhayams, the initial guru is revered as Bhagavan or Ishvara, which establishes a direct and authoritative source of verification. Furthermore, the scriptures serve as an independent and definitive source of pramana, providing clear guidelines and indicators for both the methods to attain moksha and the signs that signify its attainment. Insights from Pujya Swami Chinmayananda on the identity and role of a guru further clarify this point -

No, moksha in Advaita Vedanta is not solely a matter of faith. While faith, or shraddha, is indeed a crucial prerequisite for a seeker, as part of the sadhana-chatushtaya, it must be complemented by logical reflection and direct, immediate experience. Without this combination, faith risks remaining mere blind belief. Advaita sampradhayam stands out among various religious traditions because it offers a framework where moksha can be credibly verified and demonstrated within one's lifetime through the concept of jivanmukti. This approach contrasts with other systems that may rely more heavily on faith alone or consider moksha as an attainment reserved for the afterlife. Therefore, in Advaita, moksha is accessible through a balanced integration of faith, reason, and personal experience, ensuring that it is both believable and achievable in the present life. For further insights, refer to "Need for a Guru and Duty of a Guru" by Pujya Swami Chinmayananda -

<< Side question - If you dream that you got moksha, will you really get moksha? If "No", then what is the guarantee that any self-assessed feeling of having attained moksha is not just one's dream? >>
No, dreaming of attaining moksha does not equate to actually achieving moksha. A self-assessed feeling of moksha may not necessarily reflect true moksha-jnana. This is precisely the trap mentioned earlier—mistaking any profound experience for genuine moksha. Moksha is not just any experience but specifically the genesis of 'brahmakara vritti'. Only this definitive vritti constitutes moksha. To distinguish true moksha-jnana from mere experiences or dreams, it is essential to rely on internal and external identification based on indicators provided by a guru or the scriptures. These indicators help assuage doubts and provide a framework for recognizing genuine liberation.
However, it is important to acknowledge that this reliance is a provisional concession given our current state of ignorance and limited understanding. Ultimately, with Brahma-jnana or moksha-jnana, there remains no doubt whatsoever. The clarity and radiance of this knowledge are unmistakable, akin to the brilliance of countless suns or the sharp clarity of an amla held in one's palm. This profound certainty distinguishes true moksha from mere dreams or transient experiences.
<< How could we know that internal verification is possible if it cannot be explained to anyone else? The only possibility is if Sruti mentions this. But assuming we take an over all view, there would be disagreements on the interpretations of Sruti statements too. >>
Your concern is valid only if the Self/Atman/Brahman is perceived as distinct—whether as sajatiya, vijatiya, or svagata—from oneself. In reality, the Self is not an external or separate or distinct unknown entity, even though it cannot be fully articulated to others. The true essence of "I," "you," and "oneself" is intrinsically the Self/Atman/Brahman. Misunderstandings about one's true nature arise from ignorance, leading to varied and sometimes conflicting interpretations of Shruti. Regardless of one's beliefs about their individual identity, the fundamental truth about the nature of "I" remains the same & immutable. Internal verification is achievable because the moksha-siddhanta directs attention solely to realizing the true nature of "who I am." This allows an individual to definitively realize their own Self. Swami Sankaracharya's Bhashya on the Brahmasutra Chatushtri drives home this point, highlighting that true knowledge of the Self transcends mere intellectual understanding and is experientially confirmed in this life itself.
<< Well, if Bhagavan thinks I deserve to be saved, He will save me. Else, He will not. I am not sure, if my hoping will make any difference. >>
Indeed, sharanagati and the grace of Ishvara/Bhagavan are of utmost and absolute importance in the attainment of moksha in Advaita siddhanta. According to the teachings of Swami Sankaracharya, any amount of personal effort is completely incapable of achieving moksha. In the complete absence of any personal endeavor, moksha can only be attained through total and unwavering surrender from the seeker combined with the complete grace of Ishvara. In the Advaita Vedanta tradition, even the slightest imperfection in surrender—such as 99.9999% sharanagati—renders moksha unattainable. This underscores the necessity of 100% surrender, which does not entertain any conditional thoughts like, "Either He will save me, or He will not." The emergence of Brahmakara vritti is entirely dependent on Ishvara's grace responding to the individual's full & absolute surrender. Swami Sankaracharya emphasizes that without this absolute surrender Bhgavan / guru and divine grace, liberation remains impossible
