Handoff — Aphelion at 100 Pages

What Was Accomplished This Session

Started at 83 pages, ended at 100. Everything pushed to spinchange/aphelion, GitHub Actions deployed.

Notes Added (17 new)

Outer solar system mythology cluster (6):

• neptune-planet, myth-poseidon, crossing-neptune-poseidon — blue planet / sea god; found by inferring what could not be seen; Triton moon chain
• pluto-dwarf-planet, myth-hades, crossing-pluto-hades — deliberate crossing; excluded Olympian = demoted planet; every moon is an underworld figure

Space exploration (3):

• hubble-space-telescope — COSTAR fix, deep fields, dark energy, Hubble tension
• new-horizons — Pluto flyby 2015, Tombaugh Regio heart, Arrokoth contact binary
• cassini-huygens — 13 years at Saturn, Huygens/Titan, Enceladus ocean, Grand Finale

Astrophysics and cosmology depth (8):

• white-dwarf, nebula, andromeda-galaxy, quasar, cosmic-inflation, fermi-paradox, moon, compass

Provenance Work

Established a clean pattern this session: crawl before writing for all factual planet/mission notes.

Crawls run (all via local crawler, no Firecrawl rate limits):

• Neptune, Pluto, Poseidon, Hades, Triton (moon), Hubble, New Horizons, Cassini-Huygens, White dwarf, Nebula, Andromeda Galaxy, Quasar, Cosmic inflation, Fermi paradox, Moon, Compass — all indexed in Supabase

Also backfilled neptune-planet.md and myth-poseidon.md which were initially written from training knowledge.

Crawl method for URLs with parentheses (e.g. Triton_(moon)): the MCP tool execute_source_crawl returns 0 pages for these. Use instead:

$urls = @"
https://en.wikipedia.org/wiki/Triton_(moon)
"@
$tmpFile = "$env:TEMP\aphelion_crawl.txt"
Set-Content -LiteralPath $tmpFile -Value $urls.Trim() -Encoding utf8
Set-Location "C:\Users\executor\Documents\vulture-nest\02_System\vulture-ingest"
python crawl.py --file $tmpFile --delay 5 --pages 1

This uses the local crawler directly and handles parentheses fine.

Batch crawl multiple URLs — same approach, multiple lines in the here-string, one URL per line.

Natural Next Directions

Ordered by leverage / graph density:

1. Complete the planetary mythology chain

• crossing-eris-eris — Eris (goddess of strife) / Eris (dwarf planet that caused Pluto's demotion). Strife named for strife; the most on-the-nose deliberate crossing in the system. eris-dwarf-planet already exists; myth-eris does not.
• myth-eris — goddess of discord, thrown apple, Trojan War chain

2. Titan (moon)

• titan-moon — Cassini/Huygens already in vault; Titan gets extensive coverage in cassini-huygens.md but deserves its own note. Mythologically: the Titans (Cronus's generation); Saturn's largest moon named after them. Wikipedia crawl: https://en.wikipedia.org/wiki/Titan_(moon)

3. Enceladus (moon)

• enceladus-moon — the ocean world; best life candidate in the solar system after Mars; Cassini's most significant discovery. Wikipedia: https://en.wikipedia.org/wiki/Enceladus_(moon)
• Enceladus in mythology: one of the Giants, buried under Mount Etna; his struggling causes earthquakes — fitting for a geologically active moon.

4. Deepen the navigation cluster

• dead-reckoning — estimating position from last known fix, speed, and heading; the backbone method for 500 years of ocean sailing; links celestial navigation, compass, and longitude
• sextant — the instrument; replaced the astrolabe; measures angle between celestial body and horizon

5. Black hole depth

• event-horizon-telescope — M87* image 2019; Sgr A* image 2022; VLBI; links black-hole, milky-way, andromeda-galaxy. Wikipedia crawl available.

6. More mythology crossings

• crossing-eris-eris (see above)
• Consider: Charon (moon) deserves a crossing note — Charon the mythological ferryman / Charon the moon that orbits Pluto in a binary dance. This is partly covered in crossing-pluto-hades.md but could be standalone.

7. Cosmology depth

• multiverse — eternal inflation produces bubble universes; connects cosmic-inflation; philosophical status
• lambda-cdm — the standard model of cosmology; ties together dark matter, dark energy, CMB, BBN
