Second half of the design session. The realisation that resets the whole cost
budget: everyone shares one seed per season, so there is exactly one world per
season and the composer never runs on a player's machine. It runs once, on a
build box. Not "fast enough for a loading screen" -- "runs overnight". It can
generate a thousand candidates, keep eight, and let Jahni veto the season before
it publishes. What ships is the seed plus the chosen parameter vectors.
The measurement pass itself is one coarse grid and one flood fill, producing one
feature vector that serves validation, danger and rarity at once. Noted the one
place coarse sampling can lie -- a wall thinner than the sample spacing makes
sealed spaces look connected, which would pass the primordial-law check on an
impassable strate. Coarse to find the route, full resolution to confirm it.
And the answer to "how do we ever judge what's good": the judge is the corpus,
not a model. Good never gets defined, only collected -- strate-level thumbs
up/down, player behaviour, and best of all where players choose to snapshot
their home, which is an ungameable "I love this place" that costs nothing to
collect. Known risk written down: promote only what you already liked and the
system converges on a comfortable middle.

A long design conversation, written down as it happened. The headline: the
op stack's "Phase 3" is REOPENED. Asked what the world was missing, Jahni
described exactly it -- the system assembling worlds from data assets and a
seed -- so the 2026-08-16 handoff's "do NOT start Phase 3" is superseded.
Then a correction that moved the whole thing a level deeper: he does not want
to author strates either. The system must INVENT them. He authors raw content
(operators, meshes, materials, sounds, creatures) and tags it; everything above
that is composed and measured.
Decided along the way: worlds are wiped every 6-12 months, which dissolves the
"generation is frozen forever once public" problem -- generation is frozen only
within a season. Shared player builds are blueprint structures, vote-ranked.
Housing is an instanced level built from a snapshot of land the player chose.
Danger is depth x a per-strate multiplier, not a sort. Every strate has a
findable entrance and exit -- built first, generated around.
The range problem turned out cheap: don't roll 73 parameters independently
(that is what makes mush), blend known-good ones with FStrateGenerationParams::Lerp,
which already exists and already blends the whole field set. Ranges come from
the spread of the existing corpus, not from authored numbers. Verified against
the code: the X-macro is in sync with the struct, only Alpha differs.
Recurring mechanism, arrived at three separate times: measure, don't declare --
and promote what measures well back into the corpus, so the system's vocabulary
grows from its own history.
