FA-77796 / Legal deadline computation / Open access
Per-defendant removal deadlines with a one-year diversity bar: bar scope · case 01
The one-year bar is applied to a federal-question case.
ROOT CAUSE
The one-year bar is applied to every case.
VERIFIED REPAIR
At the bar scope decision use `diversity`, leaving the other decision sites of the model unchanged.
Unsuccessful approach: The partial repair `diversity or len(defendants) > 1` applies the bar to any multi-defendant case.
Case contract
Stipulated: each defendant [name, served, received] has 30 days from its own trigger, where the trigger is formal service, or later receipt of the pleading when received (not None) after service; a courtesy copy received before service does not start the clock. A deadline on a weekend or listed holiday moves to the next open day. In diversity cases removal is additionally barred after one year from commencement (anniversary, never moved): the deadline is capped there, and a defendant whose trigger is after the bar gets "barred". Return [[name, deadline or "barred"]].
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.
