मुष्टिक 'fist' rebus: goldsmith
Meaning of 'goldsmith' is validated by the etyma which are semantic expansions of the Bhāratīya sprachbund word: muka 'blow with fist' (Sindhi) rebus: mũhe 'ingot' (Santali): मुष्टिक a partic. position of the hands rebus: मुष्टिक a goldsmith L.; (pl.) of a despised race (= डोम्बास्) R.;N. of an असुर Hariv.  अ-क्षर--मुष्टिका f. the art of communicating syllables or ideas by the fingers (one of the 64 कलाs) वात्स्यायन

The etyma Kur. muṭkā ʻfistʼ Prj. muṭka ʻblow with fistʼ are cognate with phonetic forms: Ku. muṭhagī,
muṭhkī f. ʻblow with fistʼ, N. muṭki, muṛki, M. muṭkā (CDIAL 10221). This suggests the basis for a hypothesis that an early spoken form in  Bhāratīya sprachbund is: muka 'blow with fist' (Sindhi)(CDIAL 10150). This is read rebus: mũhe 'ingot' (Santali) mũhã̄ = the quantity of iron produced at one time in a native smelting furnace of the Kolhes; iron produced by the Kolhes and formed like a four-cornered piece a little pointed at each end; mūhā mẽṛhẽt = iron smelted by the Kolhes and formed into an equilateral lump a little pointed at each of four ends;kolhe tehen mẽṛhẽt ko mūhā akata = the Kolhes have to-day produced pig iron (Santali).

There are many orthographic variants of the Sign 342. See for example, variants presented in ASI 1977 Memoir (Also called Mahadevan Concordance).

Sign 342 is orthography of ‘rim-of-jar’. This is read rebus as karṇaka ‘rim of jar’ rebus: karṇī 'engraver, supercargo' is echoed in Telugu. Tamil, Kannada expressions as a village accountant, writer, clerk. Marathi expressions are: गांवकुळकरणी gāṃvakuḷakaraṇī m The hereditary village-accountant: in contradistinction from देशकुळकरणी District accountant. kāraṇika m. ʻ teacher ʼ MBh., ʻ judge ʼ Pañcat.

(Monier-Williams) rebus:karṇī 'supercargo', 'engraver' (Marathi). In spoken form, the word is pronounced kankha as in Santali with the semantics 'rim-of-jar'.

The semantics of the homonym karṇī 'engraver' is echoed in Telugu. Tamil, Kannada expressions as a village accountant, writer, clerk:

కరణము karaṇamu. [Skt.] n. A village clerk, a writer, an accountant. వాడు కూత కరణముగాని వ్రాతకరణముకాడు he has talents for speaking but not for writing. స్థలకరణము the registrar of a district. కరణము n.

Thus, I submit that the Sign342 signifies कर्णक karṇaka'rim-of-jar' and is read rebus in Meluhh (Bharatiya sprachbund, speech union) as karṇī 'supercargo', 'engraver, scribe.'

That is, the most frequently used sign of Indus Script, Sign 342 is a signifier for a scribe, supercargo 'a representative of the ship's owner on board a merchant ship, responsible for overseeing the cargo and its sale.'
