Carry the SSI reconcile per-pass trajectory through raise and record (#447)#448
Merged
Conversation
…e and record populace#447: the Build M dense arm failed the #431 runaway cap after 3 passes (delta 749,467 vs cap 658,513, 11.4% vs 10%), and nothing survived the raise except the final line - no artifacts, no per-pass deltas. Converging-but-over-cap (cap mis-sized for the dense frame's equilibrium) and oscillating/diverging (real defect) demand opposite remedies, and the trajectory is the only way to tell them apart. Record each pass's national_swap_delta / sanity cap / within_bound in a pass_history that rides BOTH the success reconciliation record and the terminal RuntimeError message ("Pass trajectory: pass 1: delta=... cap=... within_bound=...; pass 2: ..."), so a failed run's log carries the adjudication evidence. No gate behavior changes - same cap, same raise condition. Both reconcile tests extended and fail without the instrumentation: the fail-closed test asserts the trajectory in the raise message, the fresh-pair test asserts pass_history in the reconciliation record.

…ation) (#452) Fixes populace#447. The #431 cap (0.10 x fresh national) was sized on sparse behavior: measured sparse deltas run 7.1-8.0% across attempts 9-16. The dense arm's #448-instrumented trajectory (af02c91, full pool) converges monotonically 11.97% -> 11.64% -> 11.38% with decelerating decrements (asymptote ~10.6%) - not a runaway, but structurally above 0.10 on the same #424-undercounted candidate universe, and unreachable by more passes alone. Per the maintainer's adjudication: the dense arm gates at 0.12 x fresh national; sparse keeps 0.10. The delta and the ratio used are recorded in the reconciliation payload, the pass trajectory rides both the success record and the terminal raise (#448), and both caps converge back to one number when #424 restores the candidate universe. Tests: the fail-closed reconcile case recalibrated above BOTH ratios (+1.1M ~ 14.9%, so the dense ratio cannot flip it); a new delta-level test pins the measured dense equilibrium class (11.42%) as in-bound on 0.12 and out-of-bound on 0.10, with >12% still refused on dense.

Part of #447 (instrumentation step — the adjudication itself follows the dense rerun).
Why
The dense arm's SSI reconcile failed the #431 runaway cap after 3 passes (delta 749,467 vs cap 658,513 — 11.4% vs 10%) and left no evidence but the final line: the raise fires before any diagnostics artifact is written, so the pass-by-pass trajectory is unknowable post-hoc. Converging-but-over-cap (cap mis-sized for the dense frame's equilibrium — the #431 adjudication pattern) and oscillating/diverging (real defect) demand opposite remedies.
What
pass_historyrecords each pass'snational_swap_delta/national_swap_sanity_cap/within_bound.ssi_take_up_reconciliation.pass_history) and the terminal raise message (… Pass trajectory: pass 1: delta=… cap=… within_bound=…; pass 2: …), so a failed run's log alone carries the adjudication evidence.Tests
Both existing reconcile tests extended, each failing without the instrumentation: the fail-closed test asserts the trajectory in the raise message; the fresh-pair test asserts
pass_historyin the reconciliation record. Full builder suite green.Next per #447: rerun the dense arm (warm checkpoint) with this in place, read the trajectory, then adjudicate cap-vs-defect.
