ℹ️ 🦄 Downstream fork

This fork started from Dev v1.0.0 and has been through 2 sync cycles and 2 customization rounds. Custom fields are preserved across every sync. Upstream chaos is kept at bay by selective adoption.

Unicorn Dev has been through two upstream upheavals and come out the other side with their sparkles intact. This page shows the complete journey.

Ownership

Entity: Unicorn Dev 🦄
Type: Downstream fork
Upstream: Dev ColourModel
Forked from: v1.0.0
Last synced: v5.0.0 (Synced from Dev v3.0.0)

The journey (v1.0.0 → v5.0.0)

Version	What happened
v1.0.0	🐣 Forked from Dev v1.0.0 — 7 identical colours
v2.0.0	✨ Added custom: sparkle_level, glitter_mode, unicorn_power
v3.0.0	🔄 Sync Wave 1 — cherry-picked from Dev v2.0.0
v4.0.0	✨ Added custom: rainbows_per_second, magic_spell
v5.0.0	🔄 Sync Wave 2 — cherry-picked from Dev v3.0.0

v4.0.0 — more custom fields

Field	Type	Notes
rainbows_per_second	Integer	How many rainbows per second can this unicorn produce?
magic_spell	String	The spell currently active

Both are Unicorn-only — upstream has no idea they exist, so syncs can never touch them.

Sync Wave 2: evaluating Dev v3.0.0

Change	Decision	Rationale
colour_1: Integer → Boolean	❌ DECLINE	"Red EXISTS. It's not a boolean question."
colour_3: String → Integer	❌ DECLINE	575 nm is meaningless to a unicorn
colour_5: 🗑️ deleted	❌ DECLINE	"Blue is not a myth. Blue stays."
colour_6: Float → String	✅ ADOPT	Was already String in Unicorn (had declined prev change)
fave_colour: 🗑️ deleted	❌ DECLINE	"We just added this! Keep it!"
mood: NEW	✅ ADOPT	Colours have feelings too
rgb_tuple: NEW	✅ ADOPT	Useful for precise colour matching
is_neon: NEW	✅ ADOPT	Unicorns love neon
wavelength_min: NEW	✅ ADOPT	Fine, we'll do some science
wavelength_max: NEW	✅ ADOPT	Fine, we'll do some science
Custom fields	🛡️ PRESERVED	Always immune
