Does a primary or archival source confirm the Amicable Society split its fixed annual dividend fund among claimants proportional to shares held, rather than equally per claim?

This capture directly answers question-verify-amicable-society-dividend-distribution-mechanism-primary, which was routed from claim-amicable-society-1706-fixed-dividend-fund-divided-equally-per-death after that claim's proportional-to-shares detail was found to rest on a single Tier 2 secondary account (Tontine Coffee-House) with no independent primary cross-check. This session made a fresh attempt at each of the four leads that question named: a clean re-extraction of the 1706 pamphlet, Cornelius Walford's 1885 essay, Geoffrey Clark's Betting on Lives (1999), and M. E. Ogborn's Equitable Assurances (1962).

Bottom line: no primary or archival source was located this session that confirms or denies the shares-proportional distribution mechanism. The existing Tier 2 secondary claim is not contradicted, but it is also not strengthened — and one thread of investigation (checking the secondary source's own citation practice) makes the existing Tier 2 status look slightly weaker than previously assumed, not stronger.

Claim: A fresh extraction pass of the 1706 pamphlet still does not yield a legible distribution-mechanism clause

Claim type: technical-mechanism. Floor: Tier 1-2 required. Met: Tier 1 source, but inconclusive on this specific point.

The 2026-07-22 capture's attempt to read the 1706 pamphlet's dividend clause via extract_pdf failed with an HTTP 500 and fell back to an OCR'd djvu.txt transcript read through WebFetch. This session, the same archive.org item's /download/ PDF endpoint resolved successfully through extract_pdf (tls: verified) — a genuine technical improvement over the prior attempt. The resulting pdftotext extraction is still severely garbled by period typeface and scan noise, but it independently reproduces the same substantive content as the earlier OCR pass: "The Dividends to be added amongſt the Qlaimants... commencing from the 15th of Marth,... in the follow[ing] Proportion, VIZ. The firſt Yer 2000... at leaſt Anqually ever after." The clause confirms a fixed, guaranteed annual fund (already established in claim-amicable-society-1706-fixed-dividend-fund-divided-equally-per-death), but the specific wording of "the following Proportion" — which would state whether the fund is split by shares held or some other rule — is not legible in either extraction pass. This is now two independent extraction attempts, via two different fetch paths, converging on the same gap rather than the same answer.

Claim: The secondary source carrying the shares-proportional claim attaches no specific citation to that sentence

Claim type: historical/sourcing-provenance. Floor: Tier 3-4 acceptable for characterizing a source's own citation practice; recorded here to explain why the underlying mechanism claim stays at Tier 2 rather than being treated as corroborated.

Tontine Coffee-House (Daniel DeMatos) is the sole existing source for "At the end of each year, the collections were split amongst heirs of deceased members in proportion to the shares those members owned." A targeted re-fetch this session, asking specifically what footnote is attached to that sentence, found none: the sentence appears in the body text with no inline citation, and Walford (1885) and Clark (1999) are named only in a general further-reading list for the piece as a whole, not tied to this specific claim. This does not make the claim false — DeMatos may simply have omitted inline citation for a fact he considered well-established — but it means the existing vault claim-note's framing ("Tontine Coffee-House, citing Walford's 1885 ... and Clark's ... 1999") slightly overstates the traceability of this one sentence. The claim remains Tier 2 (named author, own venue) but should not be read as "Tier 2 with a visible citation trail to Walford and Clark" — it is Tier 2 on the author's general credibility alone, for this specific sentence.

Claim: Walford's own 1885 essay is freely accessible (not paywalled), but its located installment does not yet reach the Amicable Society's 1706 mechanics

Claim type: historical / bibliographic. Floor: Tier 3-4 acceptable.

The JSTOR copy of Walford's essay (stable/41135809) returned HTTP 403 both in the 2026-07-22 and this session's attempts — effectively inaccessible without institutional access. However, this session located a freely hosted copy of the same essay's first installment directly on the Institute and Faculty of Actuaries' own site: actuaries.org.uk/system/files/documents/pdf/0114-0133.pdf, pages 114-133 of Journal of the Institute of Actuaries vol. 25 (1885). Read in full via extract_pdf, this installment covers the Experimental Period and the early Speculative/Transitional Period, ending mid-narrative at the founding of the 1699 and 1700 "Societies of Assurance for Widows and Orphans" and the 1704 "New Assurance Office," with the essay explicitly marked "(To be continued.)" The Amicable Society (1706) is named only once in passing ("the movement of 1706 was intended to be in the direction of permanence," p.126) with no dividend-distribution detail. Web search results reported inconsistent, unverified bibliographic details for the essay's continuation (one search surfaced "History of Life Assurance in the United Kingdom (Continued)" on JSTOR at stable/41135846 with no confirmed page range; another surfaced a claimed "(Concluded)" installment in vol. 26 (1887), pp. 436-465, which could not be independently verified — JSTOR access was blocked and no matching free-hosted PDF was found by guessing the actuaries.org.uk page-range URL pattern). These bibliographic claims are flagged [unsourced -- needs verification] rather than recorded as fact.

Claim: The central question is unresolved — no primary or archival source confirms or denies the shares-proportional distribution mechanism

Claim type: this is the capture's core finding, stated plainly per the operating spec's "valid non-outcome" provision.

After genuine effort across four named leads (primary pamphlet re-extraction, Walford's own essay, Clark's Betting on Lives, Ogborn's Equitable Assurances), no source clears the Tier 1-2 floor with a legible, on-point statement of how the Amicable Society's fixed annual dividend fund was divided among claimants. The pamphlet itself states a fund exists and is fixed but not how it is split; Walford's own essay, now freely accessible, has not yet been read in its entirety and its accessible installment predates the relevant passage; Clark's and Ogborn's books were not found in any accessible full-text form online this session (Google Books previews, if any, did not surface the relevant passage; no free full text was located). The existing Tier 2 claim from Tontine Coffee-House stands as the only source for the shares-proportional rule, and it is not contradicted by anything found this session — but it is also not independently corroborated. Marked [unverified — could not confirm or deny after search].

Further leads

• Walford's essay continuation ("Continued" / possibly "Concluded") is real but its exact volume/page location is unverified this session — JSTOR stable/41135846 surfaced as a candidate "(Continued)" entry but returned HTTP 403 on fetch; worth a library-access attempt or a direct actuaries.org.uk page-range guess-and-check campaign (0114-0133.pdf's numbering convention suggests sequential page-range PDFs exist for the same volume).
• Geoffrey Clark's Betting on Lives (1999) and M. E. Ogborn's Equitable Assurances (1962) — neither has an accessible full text online found this session; a library/interlibrary-loan read of either is the strongest remaining path to resolving this question.
• The 1706 pamphlet's certificate-of-age form text, read cleanly this session ("being full Twelve Years of Age or more, and under Fifty Five"), resolves the separate open lower-age-bound ambiguity flagged in the 2026-07-22 capture (previously OCR-ambiguous between "Ten" and "Twelve") — not part of this capture's core question, but worth folding into claim-amicable-society-1706-rules-capped-admission-age-at-55 on a future pass.
• The archive.org /download/ PDF endpoint for the 1706 pamphlet now resolves via extract_pdf (previously HTTP 500 on 2026-07-22); worth noting for any future session re-touching this item that the /download/ path succeeds where the /stream/ djvu.txt fallback was previously needed.

Entity candidates

• M. E. Ogborn — person — author of Equitable Assurances (1962), named repeatedly across this vault's Amicable Society cluster as a plausible primary-adjacent source, not yet directly read or given an entity page
• Institute and Faculty of Actuaries — concept/institution — hosts Walford's original 1885 essay as a free direct PDF (a stronger access path than JSTOR); may be worth tracking as a recurring primary-source venue for this vault's actuarial-history cluster
