The accountant's zero

Status: Anticipated · untested

Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).

This is a proposed connection between two domains, generated by a language model. It is not an article and not evidence: it sits below the evidence/publication boundary. A quantitative prediction and a named kill-dataset are attached (when registered) so the claim stays falsifiable rather than merely evocative.

Claim (verbatim)

The zero digit is celebrated as a triumph of Indian mathematics and astronomy, yet the earliest securely dated zero symbols known anywhere survive in seventh-century Southeast Asian inscriptions, including the Khmer stone conventionally cited as bearing a śaka date of 605 (683 CE) with a small round zero. This conjecture joins the famous zero to bookkeeping rather than star-science: in this region, place-value digit notation entered writing as a clerk's tool, appearing in vernacular dating and economic formulas while Sanskrit verse in the very same period and even the same monuments kept the learned word-numerals and spelled-out numbers that fit metre. The mechanism is practical — clerks recording rice, cloth, and regnal years need compact columnar numerals, while poets and priests need words that scan — so the notation's social address is visible in where it lands on stone. If it holds, the celebrated 'first zero' stops being an isolated curiosity and becomes the exposed tip of a structurally necessary world of perishable ledgers computed in place-value arithmetic, decades before any surviving mathematical text in the region.

Prediction clause (verbatim)

Across dated seventh- to ninth-century inscriptions of Cambodia, Campā, and the archipelago, digit/place-value numeral tokens will occur predominantly in vernacular-language or formulaic dating and economic contexts rather than in Sanskrit verse contexts, at a skew of at least 3:1, while Sanskrit verse passages of the same period retain word-numerals (including bhūtasaṃkhyā-type expressions) at a comparable or greater preference. Primary clause: the at-least-3:1 contextual skew of digit notation toward vernacular/economic passages; the verdict follows it.

Kill-dataset (verbatim)

The DHARMA project editions (machine-readable Sanskrit/vernacular inscriptions of South & Southeast Asia): tagging every numeral token by notation type and language context in the dated early corpus.

Nobody has run this test. The kill-data is named above. If you can run it — or you know the paper that already settles it — claim the kill or submit the prior. Kills and priors are credited here, by name, as they come in.

Novelty / leakage triage

anticipated in the literature — this exact test has never been run

The K-127 zero (683 CE) is famous and its bill-of-sale, clerical context is explicitly remarked on (Coedes 1930; Aczel), so the bookkeeping direction is anticipated; but no corpus-wide tagging of digit versus word-numeral tokens by language/register with a quantified skew has been located. Thin-field flag: specialist numeral-notation studies may exist off-web.
