re: sound.pak is fully accounted for -- the last 2 entries were named in the table

Browse Source 
static.slb (8970240 bytes, the shared SE bank) and Pj_Silph.xgs (533 bytes, XACT
global settings) both hash into the TOC. Their names come from the BANK_SE and
SETTINGS records of the very IDXD object this page documents -- I had printed
them at the top of the write-up and then reported the entries as unidentified.

9519 of 9519 now: 5100 jpn + 4382 eng + 35 root + these 2.

**2 entries are unaccounted for.** I did not identify them.
**The archive is now fully accounted for.** The last two took a correction:
I first reported them as unidentified, having looked past the fact that the
same IDXD object names them. `BANK_SE`'s single field is `Static.slb`
(8 970 240 bytes — the shared sound-effect bank) and `SETTINGS.PARAM` is
`Pj_Silph.xgs` (533 bytes — the XACT global settings). Both hash into the TOC,
and both were sitting in the table I had already printed at the top of this
page. For 18 candidate names against 9 519 occupied slots the expected number of
accidental matches is about 4 × 10⁻⁵, and these two are corroborated by being
named in the table rather than guessed.
Only `eng` and `jpn` resolve. `deu`, `fra`, `ita`, `esp` and the alternative
spellings `fre`/`ger`/`spa` produce **zero** hits, which is the measurement
