- Gateway/restart continuation: durably hand restart continuations to a session-delivery queue before deleting the restart sentinel, recover queued continuation work after crashy restarts, and fall back to a session-only wake when no channel route survives reboot. (#70780) Thanks @fuller-stack-dev.

- Agents/tool-result pruning: harden the tool-result character estimator and context-pruning loops against malformed `{ type: "text" }` blocks created by void or undefined tool handler results, serializing non-string text payloads for size accounting so they cannot bypass trimming as zero-sized. Fixes #34979. (#51267) Thanks @cgdusek, @alvinttang, and @coffeexcoin.

- Daemon/service-env: add Nix Home Manager profile bin directories to generated gateway service PATHs on macOS and Linux, honoring `NIX_PROFILES` right-to-left precedence and falling back to `~/.nix-profile/bin` when unset. Fixes #44402. (#59935) Thanks @jerome-benoit.

- Agents/heartbeat: stop injecting the heartbeat system prompt into non-heartbeat runs, preventing ordinary user replies from being suppressed as `HEARTBEAT_OK` acknowledgments. Fixes #69079. (#69278) Thanks @stainlu.
