FA-77631 / Legal deadline computation / Open access
Deemed receipt of a contract notice and a business-day response window: recipient zone · case 01
A notice sent at 15:30 in New York is treated as received before a 17:00 cutoff in London.
ROOT CAUSE
The sender wall-clock time is used as the recipient time.
VERIFIED REPAIR
At the recipient zone decision use `sent + dt.timedelta(minutes=recipient_offset_min - sender_offset_min)`, leaving the other decision sites of the model unchanged.
Unsuccessful approach: The partial repair `sent + dt.timedelta(minutes=recipient_offset_min)` applies the recipient offset to a time that is not UTC.
Case contract
Stipulated: a notice is sent at a local time in the sender zone (sender_offset_min east of UTC) and is received at the same instant in the recipient zone (recipient_offset_min). Received at or after the cutoff time (recipient local) it is deemed received the next day; a deemed day that is not a business day (weekday, not a listed holiday) moves to the next business day. The response window ends after n business days counted from the day after deemed receipt. Return [deemed receipt, response deadline].
Why this case matters
Docketing systems compute filing and response deadlines from trigger events; a wrong date can forfeit a right.

Verification & scope
Stipulated toy deadline rules evaluated offline on explicit fixtures. The contract is inspired by common court-rule structures but is not legal advice and makes no claim to reproduce any jurisdiction's rules. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
Observations recorded using Python 3.12.14 at 2026-09-29T14:49:27.258614+00:00.
