Credibility QA — §10 checklist (31 / 31 PASS)

• Evidence badges present in every section on every new page.
• All four “Why 260?” hypotheses + explicit no-consensus statement on the Maya page.
• Sun Stone correction (cuauhxicalli, not a functioning calendar) on the Aztec page.
• Both Norse negative findings (no canonical Nine Worlds list; no historical runic gematria).
• WRR + MBBK full-text links on the Methodology page.
• Long Count converter passes both anchor unit tests (era base 11 Aug 3114 BCE; era cycle 21 Dec 2012).
• Footer note “Compiled for analytical review — June 2026” on every new page.

Added

• Bibliography — consolidated reference list grouped by source quality (peer-reviewed, academic monograph, primary, encyclopedic). Every entry tells you which page(s) on the site cite it.
• Sitemap.xml — 36 URLs covering every public HTML page on the site.
• Number Lookup — enter any positive integer; get cross-cultural attestations grouped by evidence grade, computed properties (prime factorization, triangular/square/cube/perfect flags, digit sum, digital root), and an OEIS deep-link for external verification. Curated dataset of 71 entries.
• Site search — hand-rolled client-side scorer over a 48 KB index (30 pages, 246 sections). Title ×3 / heading ×2 / excerpt ×1 weights; top-25 ranked results with matched terms highlighted. Honours ?q= URL params for the schema.org SearchAction.
• 231 Gates K₂₂ visualizer — SVG, 22 Hebrew letters on a circle, all 231 chords drawn at low opacity. Hover a letter to highlight its 21 gates; click two letters to highlight the single gate between them and display the pair’s combined gematria value.

How it works

• Text: 5,000 letters from a 22-letter alphabet (A–V), with weights loosely modelled on Hebrew letter frequencies. Click Regenerate text to draw a new sample.
• Search: equidistant-letter-sequence (ELS) match-counting — at every starting position, check whether the target letters appear at fixed integer spacing.
• Null distribution: Fisher–Yates shuffle of the text, recount, repeat N times. Default N = 1,000; user can go up to 20,000.
• Output: canvas histogram of the null distribution with the observed value marked in gold; the right tail (matches ≥ observed) is highlighted in red; p-value = (count of null trials ≥ observed) / total trials. Null mean and standard deviation also displayed.
• UX: chunked async loop with progress bar + live trial counter; UI stays responsive even at 20,000 trials.

Added

• Maya Long Count — raw counter display (b’ak’tun continues past 13). Today’s date as a five-part Long Count (baktun.katun.tun.winal.kin) plus the days-since-era-base, anchored on the GMT correlation constant JDN 584,283.
• Maya Tzolk’in & Haab’ — the 260-day sacred count (13×20) and the 365-day solar count (18×20 + 5 Wayeb’) computed and displayed together. Their joint cycle (LCM = 18,980 days = 52 years) is the Calendar Round.
• Aztec / Mexica tonalpohualli — 260-day count with Nahuatl day-sign names (Cipactli through Xochitl). Caso correlation, with the explicit caveat that no single accepted correlation constant exists for the Mexica count — flagged as disputed correlation.

Algorithm validation

• Both anchor-date unit tests required by the expansion spec §7.1 pass:
  • Era base: JDN 584,283 → 0.0.0.0.0, 4 Ajaw, 8 Kumk’u (= 11 Aug 3114 BCE proleptic Gregorian)
  • Era cycle: JDN 2,456,283 → 13.0.0.0.0, 4 Ajaw, 3 K’ank’in (= 21 Dec 2012)
• Tests run on page load and report PASSED/FAILED to the browser console (non-blocking).

Edits

• Hebrew Bible — the Kabbalah Connections subsection now links to the full Sefer Yetzirah page.
• Ritual Calendars matrix — four new rows: Tzolk’in/tonalpohualli (260 = 13×20), Haab’/xiuhpohualli (365 = 18×20 + 5), Calendar Round/xiuhmolpilli (LCM(260, 365) = 18,980 days = 52 years), Maya Long Count era (1,872,000 days ≈ 5,125 years, GMT JDN 584,283).
• Sacred Numbers introduction — a new pointers card indexes numbers covered on dedicated pages: 9 (Norse), 10 (Pythagorean), 13/20/52/260 (Mesoamerican), 22 and 231 (Sefer Yetzirah), plus the Lab’s 3/4/5/9/40 profiles.
• Numeral Systems — new Section 09 on Maya vigesimal positional notation (3 glyphs, base 20, independently invented zero); a row added to the Comparison Matrix; a tetraktys cross-link added from the Greek Isopsephy section. Section renumbering: Matrix → §10, Calculator → §11, References → §12.

Changes

• All 33 HTML pages now carry the new nav block including: Greek & Pythagorean, Norse & Germanic (in Ancient Traditions), Maya + Aztec (new Mesoamerican Traditions group), Methodology (first in Cross-Cultural), Sefer Yetzirah, Number Lookup placeholder (in Interactive Tools), and Changelog.
• RSS autodiscovery (<link rel="alternate" type="application/rss+xml">) added to <head> on every page.
• Footer-links extended with Changelog and RSS on every page.

Side-fixes

• sikhism.html and cross-cultural-comparisons.html previously had unclosed <footer> markup (missing </div></footer></body></html>). Both now have properly structured footers matching the rest of the site.

Highlights

• 32 paths = 10 sefirot + 22 Hebrew letters — the text’s opening decomposition.
• The 22 letters in their explicit 3 + 7 + 12 partition: three mothers (Aleph, Mem, Shin) → three elements; seven doubles → seven planets / days; twelve simples → twelve zodiac signs / months.
• 231 gates = C(22, 2) — the complete graph K₂₂ on the circle of letters; one of the earliest explicit binomial-coefficient computations in a religious text. Sara Glaz’s 2021 Bridges paper documents the count as performed pair-by-pair as meditative practice — computation as ritual.
• Yisrael mnemonic: the name «Yisrael» re-segments as «Yesh Ra’ela» — «there are R-L-A», where Resh + Lamed + Aleph = 200 + 30 + 1 = 231 under standard gematria. Late but mathematically exact.
• Explicit factorials in SY 4:16: “two stones build two houses, three build six, four build twenty-four, five build one hundred twenty, six build [seven hundred twenty], seven build five thousand and forty” — the factorial sequence 2!, 3!, 4!, 5!, 6!, 7! stated as primary content c. 2nd–6th century CE. The 6! = 720 reading has a 620 textual variant catalogued in Hayman 2004.
• 5040 = 7! appears in two independent traditions as a recognised factorial: Sefer Yetzirah and Plato’s Laws 737e as the ideal city size.

Highlights

• Nine as the dominant Germanic mythological number, attested in Hávamál 138 (Odin’s nine nights on the windswept tree), Vǫluspá 2 (“nine worlds I remember”), Hyndluljóð 35 (the Nine Mothers of Heimdallr), and Snorri’s Gylfaginning (Thor’s nine steps; Hermóðr’s nine nights to Hel).
• The 24-rune Elder Futhark in three ættir of eight — attested on the Kylver stone (c. early 5th c.), the Vadstena bracteate, and the Grumpan bracteate.
• Negative finding 1: the Eddic sources never enumerate a complete canonical list of the “Nine Worlds.” Every modern named list is reconstruction, not transcription.
• Negative finding 2: there is no historical attested runic gematria. The 20th-century Armanen runes (von List 1908) are a romantic-nationalist invention of 18 runes, not a recovered system.
• Methodological argument: two honestly reported negatives are credibility-building, not credibility-undermining — parallel to the Sikh page’s explicit absence of Gurmukhi gematria.

Highlights

• The tetraktys (T₄ = 1+2+3+4 = 10) with its three musical consonances: octave (2:1), fifth (3:2), fourth (4:3).
• The arithmology of numbers 1–10 with attestation in Aristotle Metaphysics A5, plus the late Neopythagorean elaborations in Nicomachus and Theon of Smyrna.
• The five Platonic solids (Euclid XIII: exactly five) and the doctrinally awkward dodecahedron, assigned to the cosmos itself in Plato’s Timaeus.
• The Hippasus crisis — the flagship credibility story: a sacred-number tradition whose own mathematics falsified its central dogma. The irrationality of √2 disproved the “all is number” doctrine; the school’s expulsion (or, in the late Iamblichus tradition, drowning) of Hippasus is layered by evidence grade.
• Plato’s nuptial number at Republic 546b: Adam’s 1902 reconstruction 12,960,000 = 60⁴ ties to the Babylonian sexagesimal substrate; the passage remains a 2,000-year-old open problem.

Highlights

• The two interlocking calendars: tonalpohualli (260 = 13×20) and xiuhpohualli (365 = 18×20 + 5).
• The 52-year xiuhmolpilli ("Binding of the Years") = LCM(260, 365) = 18,980 days.
• The New Fire Ceremony at Mount Huixachtlán, anchored to the Pleiades zenith transit at midnight.
• The 13 heavens (Topan) and 9 underworld levels (Mictlan) — matching the 9 Lords of Xibalba in the K'iche' Maya Popol Vuh.
• Credibility correction: the famous "Aztec Calendar Stone" (Sun Stone) is not a functioning calendar — it is a sacrificial cuauhxicalli / temalacatl glorifying the Fifth Sun. The calendar lived in the codices, not on this monument.
• Structural comparison matrix with the Maya system, demonstrating the shared Mesoamerican calendrical substrate.

Highlights

• The vigesimal (base-20) positional system with three symbols (dot, bar, shell glyph), including one of the earliest independently invented zeros.
• The Long Count with the GMT correlation constant JDN 584,283: era base 13.0.0.0.0 = 11 Aug 3114 BCE = 4 Ajaw 8 Kumk'u; era completion = 21 Dec 2012 = 4 Ajaw 3 K'ank'in.
• Tzolk'in (260 = 13×20), Haab' (365 = 18×20 + 5), and Calendar Round (LCM(260,365) = 18,980 days = 52 years).
• All four "Why 260?" hypotheses (gestation, Venus, agricultural, solar zenith) with evidence grades and explicit "no scholarly consensus" statement.
• Dresden Codex tables: Venus (5×584=2920=8×365), Mars (780 = 3×260), Eclipse (405 lunations = 11,960 days = 46×260) — plus Aldana's 2016 empirical-observation reinterpretation as a live scholarly conversation.

Added

• Statistical Methodology — the site's credibility anchor. WRR (1994) vs. MBBK (1999) Torah-codes controversy as a peer-reviewed case study, plus a six-part toolkit applied to two worked examples (Genesis 1:1 factoring; Dresden Codex eclipse table).
• This changelog at /changelog.html — one entry per release, evidence-graded.
• This RSS feed at /rss.xml — one item per changelog entry, RSS 2.0 with autodiscovery via <link rel="alternate"> on every page.
