re(challenge): the gate's bit space is the game's 24 ACHIEVEMENTS

Browse Source 
Static only. Last commit left "REQUIREMENT is a bit index into a progress
bitfield" with the space unidentified. It is the achievement space, and both
halves are now readable off the disc and the executable.

- GamePart_Debriefing (0x8218CF38-0x82191B18) awards them: sub_8218F9A8 walks
  the on-disc ACHIEVEMENTS_REQUIREMENTS list (tables.pak #16, schema 744c0519),
  and for entry index n tests bit n, evaluates the entry when clear, and sets
  the bit when satisfied. The list is literally ACHIEVEMENT01..ACHIEVEMENT24 --
  24 entries, which is exactly where the challenge gate splits word A from
  word B.

- The XEX carries the definitions: XACH at .pe 0x8FBCBC, 36-byte records
  {id, name_id, unlocked_desc_id, locked_desc_id, image_id u32, gamerscore u16,
  pad, flags u32, 16 zero bytes}, strings from one XSTR per language (English is
  table #5). tools/xach_dump.py parses it. SELF-CHECK: the 24 gamerscores sum to
  exactly 1000, the retail total -- a wrong stride does not land on a round 1000.

- The two sources agree on ORDER independently: the requirement types
  ShootDownAircrafts 1000/10000, ShootDownShips 100, ShootDownWeight MegaTons,
  GetAllWeapons and GetAllAchievements line up with ids 19-24 exactly as XACH
  names them. So bit n <-> achievement n+1 is evidence, not inference. (Those
  last two are requirement TYPES, not debug cheats, despite how they read.)

- Corollary: TimeAttack's REQUIREMENT 16 -- the one value that sits in direct
  value-before-key adjacency, so it survives IDXD dedup -- is bit 16 =
  achievement 17, "Solar System Defense Award", i.e. finish the story campaign.
  The other five values (25-29) are >= 24 and so index word B, a second flag
  space, plausibly a challenge-clear chain. Still 🟡.

REFUTED, from the last commit: the stores to +1956 in 0x822AF278 / sub_822C8748
are NOT this singleton. That object comes from 0x822CEB30, checks a +2652 flag
and stores string POINTERS at +1956/+2024 -- and a pointer ANDed with 1<<n is
meaningless as a gate. So nothing in the image writes this singleton's +1956
field-wise, and where the mask persists (save vs Xbox profile) is open. XEX
imports are by ordinal, so absent XamUser* strings are not evidence either way.
