ritenseki 0ccf6b09f4 docs: record the triage rule — a stage element behaving wrong usually means a missing component
Two of this session's bugs had the same shape, and naming that shape is worth more than either
fix: the wash lights whipping back and forth, and the billboards spinning. In both cases the
data was fine — clip curves and serialized fields dumped clean and checked out — and what was
wrong was behaviour we had inferred on behalf of a script that does not exist.

So the default hypothesis for "this stage element moves when it shouldn't / doesn't move when it
should / moves at the wrong rate" is now written down as: the original component is missing and
something of ours is standing in for it. Not: the data was parsed wrong. That is justified by
the ledger — 728 MonoBehaviour instances are still empty, AnimationObjectController alone
accounting for 282, and every decision about what animates and when lived in those method
bodies. Data is dumpable and has repeatedly proven correct; behaviour is the part we cannot
retrieve.

Two practical corollaries go with it: check what scripts an object carried and whether we have
them ([StageScripts] plus the signature list) before suspecting the parser; and when standing in
for a missing component, say in the source whose decisions you are making, and mark whether the
rule came from bundle data or from watching reference footage. The latter is real evidence but
not ground truth, and may not hold on another stage.

The counter-example is recorded in the same breath so the rule does not become a reflex: the
black light shafts were a data problem after all — every material carries a URP Lit property
table whose opaque preset (_DstBlend = Zero) overrode the additive blend 14 of the 16 relevant
shaders declare. That one was found by dumping, and the general lesson — a stale saved-property
table can override render state, not just colour — now sits next to the existing warning about
saved properties.
