"""Scrimmage / 学園交流会. Reference: baas-reference/module/scrimmage.py.

Ported per explicit user direction (2026-08-02): 3 areas (トリニティ/ゲヘナ/
ミレニアム -- this client's rendering of the reference's own
Trinity/Gehenna/Millennium scrimmage_area_name list), choose one via the
same date-ordinal-modulo rotation story_sweep.py/event_sweep.py/bounty.py
already use, and always sweep that area's hardest (D, last-lettered) stage.

Differs from the reference's own control flow (module/scrimmage.py's
get_los/scrimmage_common_operation, which scans however many stage rows are
currently visible for the first one whose color.check_sweep_availability
reads "sss") the same way bounty.py already differs from its own reference
(module/rewarded_task.py's analogous get_los/one_detect scan): rather than a
color-based per-row SSS-availability scan across a scrollable list, this
client's Academy Select stage list is a small FIXED 4-row grid (01 A / 02 B
/ 03 C / 04 D) with no scrolling at all -- confirmed live identical between
Trinity and Gehenna, all 4 rows already 3-starred/SSS-cleared -- closer to
story_sweep_hard.py's fixed 3-row Hard-mode list than to bounty's
scroll-to-extreme design. Per explicit user direction, the hardest
(last-lettered) row is always targeted directly (config.
SCRIMMAGE_HARDEST_STAGE_INDEX), with no availability scan needed.

Genuinely new guard, no reference equivalent: the account has a real
monthly pass making every scrimmage sweep cost 0 AP (ticket-only), per
explicit user direction. Rather than assume the pass is always active,
_sweep_hardest_stage OCR-reads the AP cost the ticket-usage confirm dialog
itself states in plain text ("学園交流会チケットをN、APをM使用して、掃討を
N回行いますか?") and refuses to click the final confirm button unless that
reads exactly 0, cancelling instead -- see config.
SCRIMMAGE_SWEEP_CONFIRM_TEXT_RECT for the live-captured dialog text this
was calibrated against.

Live-recon'd against nik-gpu 2026-08-02, zero real tickets spent (the one
ticket-usage confirm dialog reached during recon was cancelled via Escape,
ticket count 30/6 confirmed unchanged before/after):

- Entry: WORK_ICON -> config.SCRIMMAGE_CARD (学園交流会 card, third card in
  the Work hub's left column, below 指名手配/特別依頼) lands on Academy
  Select. Same card-based entry pattern as bounty's 指名手配 card / arena's
  Tactical Challenge card / story_sweep's Task card.
- Academy Select's 3 area rows are a fixed list, not scrollable --
  config.SCRIMMAGE_AREA_ROW_Y indexes directly by rotation, same pattern as
  config.BOUNTY_AREA_ROW_Y.
- Each area's own stage list (reached by clicking an area row) is a fixed
  4-row grid, confirmed live identical layout between Trinity and Gehenna
  (same 入場 (enter) button x/y per row). config.SCRIMMAGE_STAGE_ROW_Y
  indexes directly by config.SCRIMMAGE_HARDEST_STAGE_INDEX (3, i.e. row 04,
  stage D) -- no OCR search needed, unlike story_sweep/event_sweep's
  longer-than-visible lists.
- The 任務情報 (task info) modal reached by clicking a stage's 入場 button
  is PIXEL-IDENTICAL in position/color to bounty.py's own stage-info modal
  (same MIN/-/+/MAX stepper coordinates, same
  (171,172,171)-vs-(251,173,152) raised/default minus-button colors, same
  cyan 掃討開始 button position) -- confirmed live. It has the SAME real
  hazard bounty.py's own config.BOUNTY_SWEEP_CONFIRM_TEXT_RECT comment
  documents at length: a second, gold 任務開始 (start mission, a REAL
  manual battle) button directly below the intended cyan one. This module
  never clicks anywhere near config.
  SCRIMMAGE_MISSION_START_BUTTON_DO_NOT_CLICK, and additionally gates the
  final confirm click on an OCR text check (_confirm_dialog_is_sweep,
  mirroring bounty.py's own) before ever committing.
- The ticket-usage confirm dialog reached after 掃討開始 is the same shared
  "通知" component SWEEP_CONFIRM_BUTTON/SWEEP_CONFIRM_CANCEL_BUTTON/
  SWEEP_CONFIRM_CYAN/SWEEP_CONFIRM_GOLD already cover (confirmed live
  pixel-identical OK/Cancel button positions to bounty's own dialog) --
  reused directly. Its own message text is genuinely new here: unlike any
  other sweep-style dialog in this project, it states its own AP cost in
  plain digits, which is exactly what the AP==0 guard above reads.
- The post-sweep result screen was NOT reached live (every dialog was
  cancelled before confirming, to spend zero real tickets during recon) --
  config.SCRIMMAGE_SWEEP_RESULT_BUTTON_REGION is seeded from bounty.py's
  own already-hardened region rather than the generic
  SWEEP_RESULT_BUTTON_REGION story_sweep/event_sweep use, since bounty's
  own history is a direct, documented warning against that generic region
  on this exact modal family (see that config constant's own comment) --
  NOT yet independently confirmed against this module's own real result
  screen.

NOT yet live-tested with a real ticket spend -- config.SCRIMMAGE_SWEEP_COUNT
is "max" (spend every held ticket in one run) per explicit user direction,
same default bounty.py's own BOUNTY_SWEEP_COUNT uses. Needs the user's
go-ahead before the first real run, matching this project's own convention
for newly-added resource-spending tasks (arena, bounty).
