… 15 objects Wraps the library's new dsp::xtc (merged upstream with gates X1-X6 green: 60.7 dB mean in-band XTC at the default geometry, 0.76 dB design-point coloration, +12 dB ceiling with reciprocal makeup). Stereo/binaural in -> two speaker feeds for a symmetric (span, distance) geometry, computed KEMAR plant, per-geometry redesign on the control thread published through the same lock-free pending/active/trash convolver handoff as panbin~ (widened to the 4-filter quad) with a one-block crossfade. 'bypass' attribute ramps over one vector for the listening protocol's A/B; help patch documents the 512-sample latency and ~12 dB makeup offset for loudness matching. Submodule bumped to AmbiTap main with dsp/xtc.h + the room~ R1-R10 verification harness. README: xtc~ entry, Wave 3 status (room~ C++ FDN is the remaining build). CI bundle count 14 -> 15; all 15 compile against the bumped pin. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_012VeadvCRUHJdneFNwRbFAM

Summary
Wraps the library's new
dsp::xtc(merged in tap/AmbiTap#12 with the PERCEPTUAL-VERIFICATION gates X1–X6 green — 60.7 dB mean in-band crosstalk rejection at the default geometry, 0.76 dB design-point coloration, +12 dB ceiling with exactly reciprocal makeup).ambitap.xtc~: stereo/binaural in → two loudspeaker feeds for a symmetric geometry. Attributes:span(degrees, default 20),distance(meters, default 1.0),regularization(0–1),bypass(ramped over one vector, for the listening protocol's A/B). Geometry changes redesign the four cancellation FIRs on the control thread and publish them through the same lock-free pending/active/trash convolver handoff aspanbin~, widened to a 4-filter quad with a one-block crossfade — the audio path never allocates. The help patch documents the 512-sample latency and the ~12 dB makeup offset so listening comparisons can be loudness-matched.Also: submodule bumped to AmbiTap main (brings
dsp/xtc.hand theroom~R1–R10 verification harness), README object entry + Wave 3 status refresh, CI bundle count 14 → 15.Test plan
