- wire schema: relax effective_end.minimum 1 → 0 + expand
description to cover line-clamp + out-of-range sentinel
(panic-fix R1 emits Some(0) when line_start=1 and range is
beyond doc end — schema must accept it)
- tests: tighten first-chunk-target boundary test to assert ≤ 2
total neighbors (3-chunk doc, N=2). Strict "first chunk →
context_before empty" not assertable until chunks.ordinal
column lands (R1 #9 architectural caveat)
- store: trim contradiction in list_chunk_ids_for_doc warning
comment — drop "good enough for sequentially chunked
markdown" phrase that conflicts with "hash sort dominates"
paragraph above
