taxsim-latest changed behavior around 2026-07-08: with opt(30)=1 the VA 2021 record that anchored test_opt30_aligns_rebate_timing now returns siitax=2568.05 with srebate=0 -- the $500 rebate is neither netted into the eligible year nor reported in srebate. That broke CI on main (the #1074 merge commit) and every PR since. Keep a plumbing test that opt(30)=1 reaches the binary; xfail the timing alignment (strict=False, so it auto-recovers if the binary reverts) until Dan answers #1089.

@PavelMakarchuk quick one — this unblocks CI for all open PRs (main has been red since July 8 due to a taxsim-latest behavior change, details in #1089). |

Superseded by #1095: the failure wasn't an upstream TAXSIM change — the bundled Linux/Windows binaries were stale (Aug 2025). With current NBER builds the opt30 test passes on all six platform/Python combinations, so no xfail is needed. Every run now also reports the binary build date (see resources/taxsimtest/README.md) to make this failure mode self-diagnosing. |

Summary
Main's CI has been red since the #1074 merge commit (July 8):
test_opt30_aligns_rebate_timingfails on every platform becausetaxsim-latest(downloaded fresh each CI run) changed behavior. With opt(30)=1, the VA 2021 anchor record now returns siitax = 2568.05 with srebate = 0 — the $500 rebate is neither booked in the eligible year (the #1068 PSL-mode premise the test asserted) nor reported insrebate. PolicyEngine's side is unchanged (2068.05 + srebate 500). Reproduced locally with today's binary:Asked NBER whether this is intentional in #1089 (it may relate to Dan's rebate-timing comments in #1084/#1088). Until then:
opt(30)=1reaches the binary;strict=False, so it flips back to passing automatically if the binary reverts.Unblocks CI for open PRs (e.g. #1065).
