Six streams were left unbooked because the source records no amount: a
pool zone with no ticket price and no attendance, a player card with no
fee column, a booking the code writes as zero. The scanner refuses to
invent a figure, and should — a wrong number in the books is harder to
find than a missing one, and it looks settled.

But "the system cannot tell you" is not "nobody knows". Finance knows
what a lane costs. This adds the screen where they say so.

/accounting/gaps — one card per gap:

  see the blocker      what exactly is missing, and why it blocks
  propose a value      a flat rate per unit, or the recorded amount
  see the consequence  "احسبلي هينزل كام" computes without writing
  commit               reason and effective date are mandatory

The reason is required because it is what turns an invented number into
a management estimate — a legitimate basis to account on, provided it is
stated, approved and attributable. The effective date is required
because backdating a rate onto years of history rewrites results for
periods already reported.

Nothing posts from this screen. It records a decision; the accrual
scanner acts on it next pass. Four new runners stay silent until a
decision exists, so the rules ship configured but inert.

Academy settlements get a different tool, because it is a different
problem: the settlement engine reads `academy_contracts` (empty) while
the 13 real contracts live in `sa_academy_contracts`. The tables are not
copies — the settlement table carries settlement_day, grace_period_days
and penalty_rate_pct, which the engine calculates with and the other
table lacks. So the tool COPIES rather than moves, with the missing
terms supplied by the accountant rather than defaulted silently, and the
source contracts keep working untouched.

Verified: gaps stay silent with no decision; a rate of 25/booking books
8,800 over 352 bookings and re-running books nothing; switching off
stops future accrual without reversing what was booked; all four
validation rules reject bad input; 13 contracts import and re-import is
a no-op. Trial balance still nets to 0.00.
