handoff

# /handoff Close the session with three separate artifacts: 1. A typed update to the daemon-owned Space Brief. 2. Durable MCP captures in that Space. 3. A chronological session log in `~/.wenlan/sessions/`. The daemon Brief is current-work authority. Its `~/.wenlan/sessions/_status/<space>.md` projection is a one-way human receipt. Never read, edit, or overwrite that receipt as authority. ## 1. Resolve repository and Space ```bash handoff_arg="<the Space name passed to /handoff, empty when none>" resolved="$("$CLAUDE_PLUGIN_ROOT/bin/resolve-space.sh" --cwd "$PWD" --arg "$handoff_arg" --new-repo-fallback 2>/dev/null)" space="$(printf '%s\n' "$resolved" | cut -f1)" source_layer="$(printf '%s\n' "$resolved" | cut -f2)" ``` If the user passed a Space name (`/wenlan:handoff <space>`), pass it as `--arg <space>` to resolve-space.sh. Print `space` and `source_layer`. Explicit pins, defaults, and mappings still win. `cwd-repo-new` is the approved first-handoff fallback: use the canonical repository basename, which the user can override through normal Space config. Do not invent any other Space name. Outside a Git repository, do not derive a new Space from the directory basename. If resolution still leaves `space` empty, skip the Brief read and typed update, do not issue Space-scoped captures, and continue with the unscoped session log and any unscoped durable captures. Outside a Git repository, a pin, explicit argument, default, or mapping still resolves a Space, and the Brie...
