dynwrap vs intsurv: at a glance
What is dynwrap?
A dormant trajectory-inference wrapper wakes up for maintenance only
dynwrap is the dynverse component that wraps single-cell trajectory inference methods behind a common interface, handling containerised method execution and the trajectory data model. The visible history is dominated by a burst of feature work in 2019 and then near-silence: the only recent release, v1.3.0, is a package modernisation with a minimum-version bump and no user-facing capability. The three entries in the feed span seven years.
What is intsurv?
A Cox cure-rate model package woke up after four years to simplify its own interface.
intsurv fits Cox cure rate models for right-censored survival data where event status may be uncertain — the case where you cannot tell whether a subject experienced the event or was never susceptible to it. The core has been stable since 2019: cox_cure() and its regularized counterpart cox_cure_net(), plus a weighted concordance index and a data simulator. After more than four years without a release, version 0.3.0 arrived in September 2025 and restructured how those two functions are configured rather than adding capability.

A dormant trajectory-inference wrapper wakes up for maintenance only
◆ Current state
dynwrap is the dynverse component that wraps single-cell trajectory inference methods behind a common interface, handling containerised method execution and the trajectory data model. The visible history is dominated by a burst of feature work in 2019 and then near-silence: the only recent release, v1.3.0, is a package modernisation with a minimum-version bump and no user-facing capability. The three entries in the feed span seven years.
◆ Where it's heading
The direction is custodial rather than developmental. The 2019 releases built out the substance — RNA velocity in the wrapper, velocity-oriented topologies, directed geodesic distances, Singularity 3.0 and sparse matrices throughout — and nothing since has extended it. The 2026 release reads as keeping the package installable against a modern R toolchain, which is what a maintained dependency of a benchmark suite needs rather than what an actively developed tool looks like.
◆ Prediction
On this evidence, expect further releases to be compatibility maintenance triggered by R or dependency changes; the entries give no indication of resumed feature work.

A Cox cure-rate model package woke up after four years to simplify its own interface.
◆ Current state
intsurv fits Cox cure rate models for right-censored survival data where event status may be uncertain — the case where you cannot tell whether a subject experienced the event or was never susceptible to it. The core has been stable since 2019: cox_cure() and its regularized counterpart cox_cure_net(), plus a weighted concordance index and a data simulator. After more than four years without a release, version 0.3.0 arrived in September 2025 and restructured how those two functions are configured rather than adding capability.
◆ Where it's heading
The package has reached the point where the methods are settled and the remaining work is ergonomics. Moving control parameters, M-step settings and penalty specification into cox_cure.control(), cox_cure.mstep() and cox_cure_net.penalty() follows the established R convention of separating tuning from the model formula, and it arrives long after the arguments accumulated. The C++ headers were placed in inst/include as early as 2019 so other packages could link against them, which suggests the implementation was always intended to be reused.
◆ Prediction
The gap between 0.2.2 and 0.3.0 makes cadence a poor basis for prediction. What the entries do support is that the interface rework is unfinished business rather than a prelude to new methods, so consolidation around the new helper functions is the likelier next step.

Frequently asked questions
What is the difference between dynwrap and intsurv?
They serve adjacent needs but don't currently overlap on shipped themes. dynwrap and intsurv are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is dynwrap better than intsurv?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. dynwrap and intsurv are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
