admiralneuro vs mirai: at a glance
What is admiralneuro?
admiralneuro is widening from Alzheimer's PET into general nervous-system findings.
The package launched in September 2025 with amyloid and tau PET analysis for Alzheimer's studies — centiloid computation, five neuro datasets, and ADAPET/ADTPET template programs. The February 2026 update is tagged twice on the same day, 0.2.0 and 0.2.1 carrying the same notes, and adds olfactory testing plus a nervous-system findings template.
What is mirai?
mirai removed its dispatcher process and added memory backpressure to the queue.
The async evaluation framework releases roughly monthly and moves fast at the architecture level. In 2.7.0 the dispatcher stopped being a separate process and became a thread, after its loop had already been rewritten in C inside nanonext one release earlier. The same release added an opt-in memory budget for queued task payloads and try_mirai(), which returns NULL immediately rather than blocking when that budget is exhausted.

admiralneuro is widening from Alzheimer's PET into general nervous-system findings.
◆ Current state
The package launched in September 2025 with amyloid and tau PET analysis for Alzheimer's studies — centiloid computation, five neuro datasets, and ADAPET/ADTPET template programs. The February 2026 update is tagged twice on the same day, 0.2.0 and 0.2.1 carrying the same notes, and adds olfactory testing plus a nervous-system findings template.
◆ Where it's heading
Development is moving from one disease area toward a general neuro toolkit: UPSIT smell-identification percentiles now sit alongside PET quantitation, and the ADNV template covers nervous-system findings broadly rather than PET specifically. Internal SDTM test data was retired in favour of pharmaversesdtm, tying the package more tightly to the shared pharmaverse data layer.
◆ Prediction
More assessment-specific compute functions on the UPSIT pattern are the obvious next step, each arriving with a vignette and a template program alongside it.

mirai removed its dispatcher process and added memory backpressure to the queue.
◆ Current state
The async evaluation framework releases roughly monthly and moves fast at the architecture level. In 2.7.0 the dispatcher stopped being a separate process and became a thread, after its loop had already been rewritten in C inside nanonext one release earlier. The same release added an opt-in memory budget for queued task payloads and try_mirai(), which returns NULL immediately rather than blocking when that budget is exhausted.
◆ Where it's heading
Two threads of work run together: cutting overhead out of the task path — thread-based dispatcher, in-process transport for synchronous daemons, lower per-element dispatch cost in mirai_map() — and making the framework safe to embed in an event loop, where blocking the host R thread is not acceptable. Deployment reach is growing too, with http_config() launching remote daemons over HTTP APIs and auto-configuring for Posit Workbench. Each release pins a minimum nanonext version, so the two packages advance as one unit.
◆ Prediction
With backpressure in place but opt-in, the open question these notes leave is whether a default memory budget arrives; continued overhead reduction and Shiny-facing non-blocking paths are the safer bet.
