engram_think_json built a NEUTRAL stance on every call — cog_stance_init with a NULL id, all axis_gain 1.0, bias_dir NULL, reliability 0.5 — and never loaded the stance the correspondence-beat had been persisting. That mattered because the faculty enters engram_think ONLY through the stance: axis_gain[k] warps the per-axis extents and bias_dir seeds the steering direction. cog_stance_init stores the faculty NAME and nothing reads it. So with a neutral stance, reason/abduce/induce/plan/analogize were byte-identical output under different labels, and confidence was pinned to 0.5 because GeoGradient.confidence IS stance->reliability. The machinery already existed and only this call site ignored it. engram_correspondence_beat_json resumes via cog_stance_from_node and persists via cog_stance_to_node under "stance-<faculty>-<hub>". Every beat's calibration was written and then thrown away on the next read. Same defect as the NULL anchor fixed in #142, one line below: a neutral argument collapsing a capability to a constant. Resume the same id the beat writes, so learning compounds across beats and cold boot. Fall back to neutral only when no stance exists — a genuine uninformed prior rather than a discarded informed one. Also emit stance_resumed, so confidence 0.5 from a learned-but-unreliable stance is distinguishable from confidence 0.5 from "no stance exists". That reporting gap is what let the neutral stance hide. Verified against a clone of the production store (13,627 nodes): before beat, no stance stance_resumed=false confidence=0.5 beat on a NON-keystone brier 0.00458568 -> 0.00329654 reduction 28.11%, n_trials 6000, reliability 0.930726, stance_written=true after beat stance_resumed=true confidence=0.930726 Confidence now equals the learned reliability instead of the uninformed prior. The keystone self-anchor correctly stays at 0.5 — calibration is deliberately refused on protected identity regions, and that refusal is now visible as resumed=true with confidence unchanged, rather than being indistinguishable from the bug. STILL OPEN: with no learned bias_dir the faculties remain identical in direction. What distinguishes abduce from induce geometrically is a design decision about how Neuron thinks, not a plumbing defect, and is deliberately left to Will.
