ixud.rs now has an IdxdObject-shaped reader, IxudObject, and build_caption_text
reads captions as FIELDS instead of pairing them with whatever token follows in
the pool.
build_demo_text token adjacency 134 ids 537 lines
build_caption_text token adjacency 3721 8074
build_caption_text record fields 4085 8800 = all of them
Verified over the whole disc by tests/ixud_records_disc.rs: 1104/1104 objects
parse, 1476/1476 records and 628165/628165 named fields reproduce their
ixud_hash, 48 positional, zero failures. The header word at 0x08 is record 0's
hash, asserted per object -- there is no schema field, exactly as for IDXD. The
module doc described a 12-byte record directory and a "schema/type hash"; both
were wrong and are corrected.
I also have to correct my own number from the previous commit. "1.3% of the
game's text" counted OCCURRENCES: each family lives in 24-45 IXUD blocks and
the same key repeats across them. Distinct text-bearing MSG_* keys number 8800,
not 44579, and every one has the <id>_<page>_<line> shape. So the real coverage
was 537/8800 = 6.1%, and I overstated the gap about fivefold. Direction right,
magnitude wrong.
The DEMO control is the sharpest evidence for the change: token adjacency finds
537 lines there, the field reader 541. It was dropping lines even in the one
family it was written for -- which is why the test now asserts "must not lose
lines" rather than "must be identical".
Same lesson twice in one session: pool adjacency is a consequence of how
records are written, not a rule of the format.
