The Giza plateau rebuilt from the survey, path traced in five eras from the
claimed First Time of 10,500 BCE to today, in which every "encoded
mathematics" claim (π and φ in the profile, the 1:43,200 Earth scale, the
Orion Correlation, the shaft alignments and the rest) is computed from the
same measurements that build the geometry.
Seked is the Egyptian unit of slope: palms of run per cubit of rise. A
seked of 5½ is the whole π-and-φ story.
What is in 1.0
| |
|---|
The guided tour (/walk/#tour/1) | The case for an older Giza in ten stops: the Sphinx's rain weathering, the valley temple's megaliths, the head too small for its body and the lion facing Leo, the midsummer sun in the horizon sign, Orion's belt on the ground, the shafts and their stars, the unfinished chamber under the rock, the Earth-scale numbers, and the Younger Dryas. Each stop moves the view and runs the eras; the text is in apps/walk/tour.json. |
The walkthrough (/walk/) | Seventeen 360-degree stations, outdoors and inside the Great Pyramid and Khafre's valley temple, each in every era it stands in, path traced in Blender Cycles at 4096 by 2048. The night station draws Orion's figure on its stars and a line from each belt star to its pyramid. |
| Five eras | The First Time (c. 10,500 BCE, theorized), the long rains (c. 7000 BCE, theorized), Giza as built (c. 2500 BCE, reconstruction), stripped and buried (c. 1800 CE, reconstruction), today (2026, survey). |
The films (/films/) | The rollback from today to the First Time, the Sphinx's sequence from lion to excavation, and a flight up the approach as built. |
The sky alignments (/alignments/) | Orion over the pyramids, the lion facing Leo, the shafts and their stars, each drawn as its strongest case with the size of its miss stated. |
The claims dossier (/docs/dossier.html) | Twenty-two claims, each with its residual, tolerance and the free choices it needs; fifteen land within their own tolerance. |
The realtime viewer (/viewer/) | The first, browser-rendered model, with live claim overlays, source presets, a section cut and a sky at any epoch. |
The rules that keep it honest
- Nothing is typed twice. Every number lives once in
data/measurements/ with a source in data/sources.json; derived quantities are computed, never stored.
- Claims are data. One YAML file per claim in
data/claims/: inputs, formulas, targets, tolerance, free choices, sources, overlay.
- Presets are preference orders over sources. Switch from Petrie 1883 to Dash 2015 and every result recomputes.
- The sky is computed. HYG 4.2 stars, Vondrák 2011 precession pinned in tests to ERFA.
- Pyramids from the survey; everything else placed, then labelled. Temples, tombs and the Sphinx stand on surveyed footprints to about a metre and are marked as visual stand-ins.
- Every era says what it is: survey, reconstruction, or theorized, the case for an older Giza drawn at its strongest.
CLAUDE.md carries the full set, and docs/plan.html the original plan.
Running it
pnpm install
pnpm test # vitest, every package, the scripts and the Blender reader (1,014 tests)
pnpm typecheck # the packages, the scripts and the viewer
python -m unittest discover -s render/tests # the path tracer's bpy-free parts
pnpm dossier # regenerate docs/dossier.md from data/
pnpm shafts # solve the shaft alignment epochs into docs/shafts.md
pnpm dev:web # the realtime viewer on a Vite dev server
pnpm site # assemble site/: landing page, walkthrough, films, alignments, viewer, progress, docs
pnpm run deploy # assemble and upload to Cloudflare Pages (https://seked.pages.dev)
The path-traced scenes are built and rendered headless in Blender 5.1
(C:\Program Files\Blender Foundation\Blender 5.1\blender.exe, not on PATH):
blender -b --factory-startup -P render/build.py -- --state built --shot panorama
blender -b --factory-startup -P render/build.py -- --queue render/queues/eras-v7.json
python render/publish.py # build/render/pano/ -> apps/walk/pano/ and stations.json
python render/film.py rollback # and `sphinx`: films cut from the hero stills
A full era queue takes about two hours on an RTX 5070 Ti laptop; long jobs
run detached through python scripts/job.py start (see CLAUDE.md, "One
session at a time"). The panoramas and films are build outputs and are not
committed; pnpm site assembles whatever is present and says what it left
out.

Where it stops
1.0 is a stopping point, not an ending. Left open:
- The First Time's lion and its figures are the weakest frames; they wait on new Meshy generations.
- Unverified records: entries from the starting sheet that nobody has yet checked against the cited page stay
verified: false, and qc.shaft.north.angle (claim C2) cannot be verified from Gantenbrink's report at all.
- Geometry holes listed in
docs/geometry-blockers.md: Khafre's casing cap, Menkaure's chambers, the mastaba field as surveyed rather than plausible.
- Next ideas: an LLM that runs a claim in somebody's own words against the model (
pnpm claim is the start of it).
How the model got here, stage by stage, is in docs/history.md
and the milestone renders in docs/progress/.
