Twelfth hand-authored Zai-Magic preset: a true scrolling spectrogram as a
pure script -- bgx feedback slide moves the whole framebuffer left (the
time axis), persist 1 keeps the history locked, and a 64-bin vertical
write head at the right edge inks pink -> red -> orange -> yellow -> white
over a deep dark navy field that only leaves by scrolling off the left
edge. The per-frame ink is computed from the live stroke geometry (coats
= 1.12 + 1.604*wpx/segl; ink = 1.1/(coats*ratio)) so overlapping columns
accumulate to full palette strength at any fps, aspect or brush width,
with per-coat adds kept above 8-bit quantization. Half-second erase phase
drains the previous preset's framebuffer, 3s 15x fill sweep paints the
navy field, stage resizes replay the sweep. EMBEDDED_SEED_VERSION
7.14 -> 7.18.1; seed re-synced (107 presets).
Operator-authorized for the strictly private self-hosted Forgejo repo:
the env template (.env.ove), a baseline database snapshot
(db/custom.db.seed) and secrets/ now ride with the repo so sandbox
reprovisions can never wipe them. dev.sh self-heals at the very top
(before bun install): .env is restored from .env.ove whenever it lacks
OVE_DIRECTORY_API_KEY, and db/custom.db from the seed whenever it is
missing — verified end-to-end against a faithful reset simulation
(both [SELF-HEAL] restores fire, 106-preset library serves, directory
proxy authenticated, browser clean).
One evidence-driven deviation from the requested values: DATABASE_URL
is file:../db/custom.db, not file:./db/custom.db — Prisma resolves
relative SQLite paths against prisma/schema.prisma's directory, so the
./ form provably breaks both the CLI (would create a fresh empty db at
prisma/db/custom.db on every boot) and the runtime (cannot open); the
../ form is the portable equivalent and is documented in .env.ove's
header. secrets/ ships with a README documenting the house-cookie file
slots (the actual cookie exports are re-added by the operator).
