feat(tri): tri t27b -- honest in-reference ratio, compile-only passes, per-spec delta - #6185

Conversation
…, per-spec delta `tri t27b status` printed "t27b 70 / reference 648" and the steward posted it; 14 of the 70 are passes where the reference fails. The card now quotes in-reference passes (56 of 648), splits them into checked (27) and compile-only (29), and lists out-of-reference passes and frontend rejects separately. doctor gains LAB-FRONTEND-DISAGREES. New `tri t27b delta` compares two lab runs per spec (REGRESSED, NEW-MISMATCH, CHECK-LOST exit 1). No workflow step added; census unchanged.

…894f Conflict in scripts/tri_loop/t27b.py: both `delta` (#6185) and `ratchet` are kept; `tri t27b` accepts status|doctor|delta|ratchet. Ledger re-blessed from lab run e0f894f: 75 pass, 582 not pass (max_not_pass 592 -> 582). faculty_board.t27 is pass -> frontend because typecheck refuses its typeless field; recorded as reference-bug (the reference path never typechecks).

Why
tri t27b status(from #6114) printedt27b 70 / reference 648, and the steward posted that number to #6063. It divides every t27b pass by the reference's pass count, but 14 of those 70 are specs the reference itself fails. The honest figure is 56 of 648 (8.6%). The epic comment has been corrected.What changes
resultsit splits them into 27 that ran a test or invariant and 29 compile-only (0 tests, 0 invariants). Out-of-reference passes and frontend rejects go on their own "not counted" line.LAB-FRONTEND-DISAGREES.

scripts/ci/test_a_t27b_tick_reads_before_it_acts.py(already in loop-tools-gate) passes locally. New checks cover the honest card, the frontend code, five delta transitions (with an unchanged spec that must stay silent), default---fromordering, and an absent run (exit 2). Mutation control: with the numerator switched back tot27b_passand REGRESSED disabled, 4 checks go red. No workflow step was added, so the census is unchanged.🤖 Generated with Claude Code
