Adaptive spot finder: sum the rings across blocks in double
The ring sigma is the cancelling difference sum2/n - m^2, and both sums were float accumulated by atomics whose order is arbitrary. Two costs: the cancellation left only ~4 digits in the variance, and the ordering moved the resulting threshold by ~0.05 counts between runs - enough to flip a pixel sitting on the hard "value >= threshold" test, and with it a connected component's size. So the GPU engine did not reproduce the CPU one and did not reproduce itself. Only the accumulators that span blocks are widened. The per-block staging stays float, because a block contributes a few dozen similar-magnitude pixels to a ring and there is nothing to lose there - that also keeps the shared-memory footprint of the hot loop, and hence its occupancy, exactly as it was: measured on a 4.5 MP frame, 0.960 vs 0.966 ms/frame (40.9x over the CPU path, unchanged). finalize_rings now does the cancellation in double and rounds to float last, which is what AdaptiveSpotFinderCPU::AccumulateRings does. The device properties are also read from the current device rather than device 0; callers round-robin engines across GPUs. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Address code-review findings; make detection limits detector-driven
One changeset, developed together in response to a review of this branch, so the files carry several of the changes at once. Full test suite passes (733 cases). Spot finding - Split ImageSpotFinder into Detect() (flag strong pixels - the expensive per-pixel pass) and ExtractSpots() (CCL + min/max-pix + resolution mask), with Run() = both. The per-image min-pix escalation now detects ONCE and repeats only the cheap extraction, instead of re-running the whole finder four times per frame as it did on the default path. It also keeps the winning attempt's spot list rather than re-extracting it, so the frame that is integrated is exactly the frame that was scored - which a GPU re-extract could not guarantee (float atomic ordering). - spot_finding_time_s no longer swallows indexing time, and indexing_time_s now sums every escalation call instead of reporting only the last. Detection limits follow the detector - The azimuthal-integration upper q and the spot-finding high-resolution limit are now std::optional, in the C++ structs AND in the OpenAPI schema, and resolve to the detector's own maximum (DiffractionExperiment::GetDetectorMaxQ_ recipA). Adaptive detection reads a pixel's ring from the azimuthal bins, so a pixel outside that q range could never be strong - the integration range silently bounded what detection could see, regardless of the requested resolution limit. Regenerated the C++ and TypeScript clients; the viewer and the web frontend each gained a "to detector edge" switch. Detection defaults are now per workflow (measured, not assumed) - Stills: adaptive detection, min-pix chosen per image, no resolution clipping. - Rotation: fixed-threshold finder, min-pix 2, 1.5 A limit. On a 33-crystal rotation battery, adaptive detection helped four hard crystals but deterministically broke three (a lost space group, a halved indexing rate, a collapsed merge), and the detector-edge limit cost indexing on a strong rotation set (100.0 -> 96.8%). Each is still overridable by its flag, and --no-adaptive-spots is new. Indexer seed escalation - Stop escalating once a seed's lattice explains >= 90% of the seed spots. Previously any frame with >= 80 spots always paid three indexer calls, online broker included. Merge-consistency filter - --min-image-cc gated on a per-image CC computed BEFORE the stills partiality post-refinement and never refreshed; the refiner now recomputes it, so the reported CC describes the data that are actually merged. - Replaced the per-call cc_mask argument with one MergeOnTheFly flag, so the merge, the error model and MergeStats can no longer disagree about which images are in (the --scale path merged unfiltered while its statistics were filtered). Per-image B-factor refinement (-B) removed - Measured on four serial-stills datasets: it is a no-op where the per-image fit is well conditioned and actively harmful where it is not (CC1/2 -8.1, R_meas +23.2 on the weakest large-cell set, whose fits hit their [-50, 200] bounds on 14-25% of images). It had also been silently DISCARDED since the partiality post-refinement landed - reported but not applied. Rather than fix and keep a knob with no demonstrated benefit, the flag and the whole image_scale_b_factor chain are gone: setting, scaling fit, message field, CBOR, HDF5 write and read-back, per-image plot, OpenAPI enum, viewer column and checkbox, docs. ScaleOnTheFly no longer needs Ceres at all - the fit is a linear IRLS. (The Wilson per-image b_factor is a different quantity and stays.) Stills partiality width now fits both of its components - sigma^2 = gamma0^2 + (gamma_e*d*)^2 instead of a purely angular gamma_e*d* with gamma0 pinned to 0. Fitted per crystal by least squares of dist_ewald^2 on d*^2. The angular-only width is fitted over a d*^2-dense population, so it was pinned by the high-resolution edge and collapsed at low d*: median partiality 0.008 beyond 13 A for reflections that were plainly recorded, 55% of them under the merge's partiality floor, and the survivors divided by those values - which inflated the merged low-resolution intensity scale 3.6x (~ +9 A^2 of apparent B). Measured on 5000 stills: the ramp flattens to 0.89x, no observation is dropped any more (701750 -> 716811), shell-mean CC1/2 and R-free improve slightly. Note CC1/2, R_meas, completeness and a B-refining R-free are all blind to that ramp, which is why it survived earlier validation; the cost is high-resolution R_meas (98.5 -> 101.9 shell-averaged). Removed dead code from add-then-remove churn - Prediction-time "still partiality" (unreachable: no setter), the phantom IndexingSettings::min_indexed_spot_fraction knob (getter, no setter - now the constant it always was), StillsPartialityRefine's caller-less Settings constructor and its reference to a long-gone env var, ProcessImage's unread bool return, an unused include, and a dead viewer overlay hook. Also - Viewer: the magnifier compared a QImage with itself, so its scene rect was set once ever and it could not pan into a larger dataset; the hover tail timer could fire after leaveEvent and resurrect the resolution readout outside the image. - update_version.sh regenerated the frontend lock file BEFORE bumping the version (every release shipped an off-by-one lock), and did git rm/git add on a path that has not existed since the client moved to src/client - with no set -e, both failed silently. - fpga/pcie_driver/postinstall.sh tested "[ ! occurrences > 0 ]", which is a redirect, not a test, so dkms add never ran. - Unit tests for the adaptive-threshold host functions, which had none.

Add fused GPU adaptive spot finder (azint + spot finding in one pass)
AdaptiveSpotFinderGPU does the per-resolution-ring reduction once on the GPU and drives both products from it: the azimuthal-integration profile (corrected space) and the self-calibrating adaptive spot-detection threshold (raw counts). This replaces the separate GPU azint pass and the host-side adaptive spot finder that runs on the GPU path today. On a ~4.5 MP detector it does both jobs in ~1 ms/frame versus ~40 ms for the CPU adaptive finder (~42x), with an identical spot list and azimuthal profile. The per-ring threshold math (Poisson tail + read-floored Gaussian, operating point from the false-pixels-per-frame knob) is factored into AdaptiveThreshold.h so the CPU and GPU finders share one source of truth and cannot drift. Wired opt-in via a MXAnalysisWithoutFPGA constructor flag, default on for the rugnux offline path and the interactive viewer, off for the online receiver (so the broker path is unchanged). When on, Analyze() skips the separate azint pass and lifts the profile from the fused engine. The viewer gains an "Adaptive threshold" checkbox that greys out the signal/noise and photon-count sliders (the adaptive finder uses neither). Dedicated tests exercise both products (spot-finding parity vs the CPU finder, azimuthal profile vs a standalone GPU azint) plus a speed benchmark. Validated end-to-end on lysozyme serial stills: fused == CPU-adaptive index rate and merge stats. Docs: new section 3.2 in docs/CPU_DATA_ANALYSIS.md.
