 Task-specific context packs now exist in `docs/task-context-packs.md`, giving each work type a minimal four-document starting set plus targeted reading paths. Future sessions should start with `docs/current-project-state.md`, then choose one pack from `docs/task-context-packs.md`. Additional documents should be loaded only for a named gap, with the reason recorded. Engine and UI experiments remain paused. Branch: `feature/user-workspace-ux-v0.7`.

+### Return-to-Work Note (Experiment 34)

+A single return-to-work handoff file now exists at `docs/current-handoff.md`. It carries the latest stopping point in approximately 68 lines and replaces scattered current return notes for immediate resumption. Historical evidence remains in the design log and archive. Engine and UI experiments remain paused after Experiment 25B. Branch: `feature/user-workspace-ux-v0.7`. First file to inspect when resuming: `docs/current-handoff.md`, then `docs/current-project-state.md`, then the relevant pack from `docs/task-context-packs.md`.
