Measured against real production history while validating the ancestry surface: `aj ewing / total_bases / over / 0.5` on 2026-08-28 carries a valid ORIGIN from the 18:10 cohort AND a row from the 19:03 cohort that was stamped for publication and never recorded an action. The chain is genuinely valid and the partial row is correctly excluded from it — that part of the contract held. But answering LINEAGE_AVAILABLE and nothing else presents an incomplete chronology as a complete one, which is the exact failure this surface exists to make visible, one grain finer than a whole Read. The response now carries `chronology_complete` and `unrecorded_publications`. The state is unchanged, because the chain that exists really is valid; what changes is that the gap is disclosed instead of smoothed over. Suite 397/5,498/0.
