Unattended discovery: the full poll->score->capture->brief loop can
now fire with no operator present (Sunday-morning discovery), gated
behind a new Step 0.5 contract. Fails fast instead of asking when the
profile is missing, skips triage unconditionally (candidates stay
pending), and refuses --demand --headless rather than silently
degrading.
Trigger mechanism is Claude Code's own Desktop Scheduled Tasks, not a
hand-rolled cron wrapper -- verified against Claude Code's headless
docs that a cron + `claude -p` wrapper loses observability/session-
resumption/error-recovery versus the first-party mechanism. The
fallback `claude -p` recipe is documented (README) for portability,
not built as repo code. No new source/test file; no schema change;
counts unchanged (30/20/29).
This opens the research-engine's own 2026-06-24 re-evaluation gate
against v1.0.0 product maturity for slice (e) -- surfaced to the
operator explicitly rather than built around or silently deferred.
