READINGPage 11 of the star-chart run. Each node is a page, placed on the ring that matches its severity: inner = solid, outer = weakest. Tap a node to read its note.

what works	what's weak
Real data: BSC5 (2,851 stars, V ≤ 5.5), the IAU/Delporte boundaries (88 in 89 polygons), and the JPL Standish ephemeris, verified against JPL Horizons for Oct 10 9 PM CT to within 6′ (Saturn worst at 5.1′). The precession polynomial puts Polaris closest around 2100. The ephemeris finds the Venus synodic mean of 583.92 d and the 2025 Mar 23 inferior conjunction. The gnomonic straight-line property and the galactic pole are checked exactly. The checks found two errors in the brief-era drafts (the ternary expansions and the galactic transform), now fixed. Betelgeuse computes yellow-orange, not red.	The data is a d3-celestial derivative of BSC5, not the original Harvard or CDS files (both were unreachable), and not Gaia DR3. No Moon. No refraction or nutation. Sky Atlas 2000 actually uses other projections; only gnomonic was implemented. The Alpha Cen and Proxima orbital figures, Rubin's alert rate and the M–M "1/20" are from memory. Leeluu v41 is cross-linked in name only.
Cross-linked: 17 explicit edges to earlier runs (index page). There are no text-presence checks in this run.	Next: load Gaia DR3 bright stars, add ELP Moon and nutation, and add a Horizons comparison for a second date.

Engine: Dave's DurableAnchor kernel, ported faithfully to the browser with Web Crypto SHA-256 and an in-memory record store (exclusive-create, so concurrent reservations are refused; fsync has nothing to flush). The ledger starts empty on each load. Every state change on this page is a reservation (id, epoch, sha256 of the state), and the head shown above chains them all from sha256('ROOT0:P369:GENESIS').
