Reopen an archived spec: remove the branch it left behind and put the folder back among the active specs. By default every file is kept and the spec takes a round on what changed in its description; only when asked are the analysis, the plan and the status reset as well. **Input:** $ARGUMENTS (a spec number, a full folder ID, or an issue key its title began with) --- ## Workflow The steps below are this skill's own, inside the queue's `reopen` step. Mark each one in the log, so a reader can follow the run: when it starts, write one line `reopen · Step N of X: <title> — started`, and when it ends, one line `reopen · Step N of X: <title> — done`. A step that ends the run early says `— stopped: <why>` in place of `— done`, and one that does not apply to this run `— skipped: <why>`. ### Step 1 of 7: Find the spec First write `reopen · Step 1 of 7: Find the spec — started`, and when this step ends, `reopen · Step 1 of 7: Find the spec — done`. Resolve `$ARGUMENTS` to a folder, looking under `archive/` — that is where the spec is. `aide_resolve_spec` in `_aide-spec-lib.sh` already searches both and returns `archive/<NN>-slug` for an archived spec. If it is NOT archived, stop and say so: a spec already in the active list has nothing to reopen, and resetting its files would throw away the round that is running. Then ask: "Reset the analysis, the plan and the status as well? (default: no)". No, or no answer, is the keep mode; yes is the reset mode. A headless run never reach
