Item: retry the blocker with the "wrong prefix" lesson from StageMessageSet_S02.tbl. The retry was already run and the owning doc says so: archive-naming's "13 name transformations" list already includes 2d\, eng\, hud\ and GP_MAIN_GAME_2D\ prefixes, every one scoring 0 against both the E2D pak and all 16630 entries. Reading the doc end to end first would have shown that in a minute. Recorded so the idea is not proposed a third time. What the re-open did add - two measurements the earlier passes did not make: 1. The six 2D archives share ONE key set: 711 keys, identical in all six. Intersection = union = 711; 4266 entries, 711 distinct keys. The entry names are language-independent - the language lives in the pak file name, not the entry path. That refutes any <lang>\ prefix hypothesis structurally, not merely by a zero score: if the names carried a language directory the six key sets would differ. 2. The 2D key space is disjoint from the rest of the disc - 0 of 711 appear in any non-2D archive, while disc-wide 2010 of 16630 keys are shared between archives. Sharing is common; this set never does it. The six named GP_READY_ROOM entries are all fonts - deu\GOTHICB.TTF, eng\, esp\, fra\, ita\ likewise, and jpn\HGRGE00.TTF. The doc recorded the count "6 named" without saying what they are: localisation fonts named from elsewhere on the disc, not a sample of the archive's own artwork vocabulary, so they cannot seed the dictionary attack the doc names as the last lever. Only 2 of 1106 GP_READY_ROOM keys appear in another archive. Still blocked, now for a sharper reason: the 2D names are language-independent, unshared, and absent from disc and executable alike. All fifteen artefacts byte-identical.
