adjustedCurves vs Resend: at a glance
What is adjustedCurves?
A survival curve package spending release after release correcting its own estimates
adjustedCurves computes confounder-adjusted survival and cumulative incidence curves across a range of estimators - IPTW, AIPTW, Aalen-Johansen, direct standardisation - with support for multiple imputation and bootstrapping. The recent releases are dominated by corrections to numbers the package already reported. Version 0.11.4 fixed cumulative incidence estimates under method="aalen_johansen" that were being read one time step early, which the maintainer notes could differ substantially when events are few, and added risk and event counts to the ggsurvplot conversion including correctly pooled values under multiple imputation.
What is Resend?
Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.
Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.

◆ Current state
adjustedCurves computes confounder-adjusted survival and cumulative incidence curves across a range of estimators - IPTW, AIPTW, Aalen-Johansen, direct standardisation - with support for multiple imputation and bootstrapping. The recent releases are dominated by corrections to numbers the package already reported. Version 0.11.4 fixed cumulative incidence estimates under method="aalen_johansen" that were being read one time step early, which the maintainer notes could differ substantially when events are few, and added risk and event counts to the ggsurvplot conversion including correctly pooled values under multiple imputation.
◆ Where it's heading
Multiple imputation is the recurring fault line. The standard error pooling formula was implemented incorrectly until 0.11.2, then fixed again in 0.11.3 for the bootstrapping-plus-imputation combination, and 0.11.4 added the pooled risk table values that had previously been omitted entirely. A separate thread quietly removed capability: tmle and ostmle methods went in 0.10.0, and tmle support was pulled again in 0.11.1 after the concrete package left CRAN. Feature work does happen - risk tables, contrast arguments, the extend_to_last control on IPTW curves - but it is outweighed by correction.
◆ Prediction
Expect continued estimator-level corrections rather than new methods, and a possible return of tmle support if its upstream dependency returns to CRAN, since the removal was described as temporary.
Resend
6.3INFRA · APIS
Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.
◆ Current state
Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.
◆ Where it's heading
Resend is treating agents as the next class of sending client and building the authorization and discovery plumbing they need before that traffic arrives. The progression is legible: authenticate third parties (OAuth), be callable (MCP), be installable per vendor (Codex, Claude), then be installable by standard. The Cancel Broadcast API is the first sign of the next phase — once non-human callers can schedule sends, the ability to revoke one programmatically stops being a convenience.
◆ Prediction
Authorization and discovery are covered and reversibility has now started; the remaining gap is what an agent is permitted to send in the first place, so scoped per-agent sending limits or approval gates before dispatch are the natural next piece.
