admiralvaccine vs mirai: at a glance
What is admiralvaccine?
Vaccine ADaM templates exist and are maintained, but development has slowed to housekeeping.
admiralvaccine provides vaccine-specific ADaM templates and vignettes — ADCE, ADFACE, ADIS, ADSL — on top of admiral. The last two releases contain no functional change at all: 0.5.0 is maintainer handover, template fixes and lint config, and 0.6.0 is CRAN documentation compliance plus an ecosystem-wide Ask AI widget. Real work was last visible in 0.4.0's criterion-flag deprecation.
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.

◆ Current state
admiralvaccine provides vaccine-specific ADaM templates and vignettes — ADCE, ADFACE, ADIS, ADSL — on top of admiral. The last two releases contain no functional change at all: 0.5.0 is maintainer handover, template fixes and lint config, and 0.6.0 is CRAN documentation compliance plus an ecosystem-wide Ask AI widget. Real work was last visible in 0.4.0's criterion-flag deprecation.
◆ Where it's heading
The package has moved from building out vaccine domains to keeping them on CRAN. Each release tracks whatever admiral changed upstream and clears whatever CRAN flagged, and the changelogs have shifted from derivation notes to merged-PR lists. Maintainer churn in 0.5.0 is the clearest sign that this is a maintenance-mode package inside an otherwise active ecosystem.
◆ Prediction
The next release most likely continues the pattern — dependency and documentation alignment with admiral core plus deprecation follow-through — unless a new vaccine reporting requirement forces domain work.

2.5ANALYTICS
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.
