# deckops-smoke-test.sh — verify a fresh DeckOps setup end-to-end before any real edit.
#
# Builds the shipped 3-slide op sequence (smoke-test-ops.txt) against a uniquely-
# named copy of the speaker's template and reports where the output landed, so the
# user can open it in PowerPoint AND Keynote and confirm no "Repair" prompt. Given
# the history of lost work with other deck tools, this runs before the real edit.
#
# Usage:
#   deckops-smoke-test.sh <templatePath> [outDir]
#
#   templatePath  the speaker profile's infrastructure.template_pptx_path.
#                 Read-only — the script copies it.
#   outDir        where to leave the built deck (default: a mktemp -d dir).
#
# Prerequisites: DeckOps.pptm open with the DeckOps module imported, macros
# enabled, Automation consent granted. Run deckops-doctor.py first — a
# `status` other than `ok` means this will fail for a reason already diagnosed.
#
# Stdout: one JSON object — {"ok":true,"output":"<path>","slides":3,"base":"<path>"}
# Stderr: actionable diagnostics. Exit non-zero when the build did not produce a deck.
#
# The copy is uniquely named on purpose: PowerPoint keys open decks by filename and
# silently hands back an already-open same-named deck.
