Use N intervals across an N-bin IQ FFT span. Share bin windows and frequency conversion across spectrum rendering, waterfall columns, and peak-jump tuning. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Use containing FFT intervals for cursor and marker lookup. Extend the final rendered interval and derive waterfall columns from each drawn row. Use captured-frame coordinates for lab peaks and recall. Address the approved geometry review of musithang#12. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Keep existing IQ profiles at -120 to 0 dBFS with a 500 ms trace-age limit. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Address musithang#13 review with shared range-safe zoom, explicit display validation, capability-based initialization, and budget-aware FFT pacing. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Extract backend-neutral control and math helpers for the tinySA prerequisites. Preserve finite IQ averaging, peak decay, noise-floor calculation, and RX session behavior. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Address musithang#14 review with documented availability and parameter contracts, buffer preconditions, and boundary regressions. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Adapt display tests to the geometry window API while keeping each preparation layer independently testable. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Add backend-neutral calibrated trace acquisition, measured-point publication, power RX control, and capability-aware layout fallback. Preserve IQ behavior through the shared prerequisite contracts. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Add hardware-tested tinySA discovery and calibrated spectrum acquisition on the generic power-trace path. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Publish a uniform grid for float-rounded firmware points and preserve the effective center after edge-clamped scans. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Accept the firmware's bounded float grid variation using measured endpoints. Clamp duplicate-producing spans and retain edge-shifted centers for later tuning changes. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Wait for the counted scan frame to close after the firmware acknowledges abort. Stop the worker if the serial stream cannot be synchronized. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Enable the Ultra input with its automatic threshold and submit each range as one scan. This keeps path selection and calibration in the verified firmware. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Keep Basic devices on one explicit LOW or HIGH connector and expose the choice through device selection. Normalize firmware frequency positions onto an endpoint-preserving display grid owned by the backend. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Treat the selector input as an explicit override so a bare serial path does not replace a persisted HIGH choice. Report invalid selectors and align the Basic model limit with the supported firmware. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>

Depends on #7 and its three prerequisites. This stack adds tinySA support through calibrated power traces. This branch will be rebased onto
mainafter #7 lands.The foundation had no concrete analyzer discovery or serial protocol implementation. It could not communicate with a tinySA.
This PR adds model-aware discovery and a sole-owner serial worker. The worker publishes validated dBm traces for spectrum and waterfall views on existing firmware. #9 extends the backend to native wide sweeps.
