 * @guardrail         pattern_id_stability
 * @routes_to         log10x_pattern_examples, log10x_pattern_trend
 * @_audit_rationale  Pairs current-window byte presence with 30d first-seen probe (fetchFirstSeenBatch) keyed on locally-derived tenx_hash so pattern_hash is snapshot-independent, then filters patterns whose first-seen age is inside the recency window. Identity-stable separation of new-vs-changing stories an agent cannot recompose from raw PromQL.
 *
 * log10x_whats_new — patterns whose first-seen timestamp falls inside a
 * recency window.
 *
 * Answers "what showed up recently?" — distinct from `top_volume` (current
 * cost ranking) and `whats_changing` (delta vs baseline). New patterns
 * have no baseline, so any "delta math" would be meaningless; this tool
 * exists so they get a clean home and don't pollute the changing-vs-baseline
 * surface.
 *
 * Implementation: query bytes_per_pattern in the current window to find
 * candidate hashes, then for each hash query the 30-day history to find
 * the earliest non-zero datapoint (`fetchFirstSeenBatch`). A pattern is
 * "new" when its first-seen timestamp is inside `first_seen_within`.
 *
 * Default sort: by `first_seen` recency descending (most recent first).
