All 14 DOIs added under content/ resolve, and the resolved titles match the papers the rows claim to be citing (e.g. 10.1152/ajpheart.00977.2005 → 'Evidence for absence of latch-bridge formation in muscular saphenous arteries', used as the femoral/saphenous absence row; 10.1113/jphysiol.2012.243576 → the Moreno-Domínguez Ca2+-sensitization paper used as the arteriole row). Provenance is honest rather than padded: every citation carries locator 'Abstract' with verification label ai_verified, and cells the abstract does not state are explicitly recorded as 'Not stated in the accessible record' rather than filled from memory, with a limitation stating no full text was accessible (§3.7/§3.8 handled by disclosure, not invention). Evidence direction is explicit and split into three separate records rather than bundled (§3.5), independence notes flag the paired Han/Call rabbit arms and the two Wingard rows as non-independent (§3.10), negative results and a failed search for the unresolved canine saphenous-vein lead are recorded rather than dropped (§3.11), and the excluded candidates are named. The new evidence records are stamped ai_extracted with runId/model/date, the study carries humanReviewed: false and promptVersion, and history.yaml is appended rather than rewritten (§3.14, §3.15). The criteria/method/searchProtocol blocks are only re-wrapped (YAML folding leaves the strings identical) and the criteriaHash fe5e031b8b8f is unchanged, so the freeze is not weakened; internal counts also cohere (13 vessel-level + 1 reconstitution + 2 model = the 16 rows claimed). AGENTS.md is untouched and no confidential arc/notes material appears.

The change adds a collected study workpaper, three new Evidence records, a Source entry, and a history entry, all within content/; AGENTS.md is untouched. New evidence records are clearly atomic propositions tied to single claims (VASO-E019 to C020, VASO-E020 to C020, VASO-E021 to C010) with explicit directions (undermines/qualifies) and limitations, satisfying §§3.2 and 3.5. The workpaper carefully separates sourceStatement (what was in abstracts) from editorInference, and distinguishes vessel-level measurements from models and molecular reconstitutions, complying with §§3.6 and 3.9. All added DOIs resolve per the tooling, and the text’s use of them (arterial smooth muscle latch papers, energetics in carotid, model papers, microvessel physiology) matches the cited venues, so there is no sign of fabricated citations, meeting §§3.7, 3.8, and 3.15. The study explicitly records independence relationships, negative/absent findings, failed searches, and search limitations, aligning with §§3.10, 3.11, and 3.13. The history.yaml entry transparently logs the new evidence and its implications, preserving versioning and not overwriting prior assessments, per §3.14. Overall the changes strengthen, rather than weaken, the epistemic checks and make uncertainty and gaps explicit.

The change flawlessly executes the evidence collection step. It respects the frozen criteria (only reflowing whitespace, keeping the data hash intact), faithfully records exact provenance with honest labels (all DOIs mechanically resolved, locators strictly restricted to 'Abstract' since full texts were inaccessible), and clearly separates source statements from editor inferences. It also adheres to §3.10 by adding explicit independence notes for shared tissue preparations and to §3.11 by reporting a failed search in the limitations rather than silently dropping it.

The diff only adds study collection rows, three new evidence records, a workpaper source, and an append-only history entry; it does not touch AGENTS.md or weaken §3.15 checks. All 14 DOIs the collection adds resolve, and where Crossref returns a title it matches the paper the row claims (Dillon 1981, Wingard 1994/1997, Han 2006, Moreno-Domínguez 2013, etc.). Provenance is labeled at abstract grain with ai_verified / ai_extracted, sourceStatement is split from editorInference, directions are unbundled per §3.5, independence notes and named exclusions/failed searches are recorded, and the freeze hash is left as fe5e031b8b8f. Abstract-only extraction is a disclosed limitation, not a fabricated locator or an unratified judgment presented as human/ratified.

This is the collection PR of a two-PR pre-registered study: the criteria block in vaso-s001.yaml is re-wrapped but semantically identical under YAML plain-scalar folding, the criteriaHash fe5e031b8b8f is unchanged, and rows/findings/limitations were added only after the freeze, satisfying §3.12. All 14 added DOIs resolve per the mechanical check, and where Crossref returns titles they match the citation text exactly (Dillon 1981, Wingard 1994/1997, Han 2006, Moreland 1987, Moreno-Domínguez 2013); the DOIs without Crossref titles have volume/page patterns internally consistent with their citations (e.g. 10.1152/ajpheart.1995.269.5.H1590). Provenance is scrupulously honest: every cell states 'Abstract read at native verification' with locator 'Abstract', label ai_verified, and unstated fields recorded as unstated rather than filled in — exactly what §3.8 requires when full text is inaccessible, and the abstract-only limitation is disclosed prominently rather than buried. Evidence directions are split cleanly (two undermines, one qualifies) per §3.5, sourceStatement/editorInference are separated per §3.9, independence notes mark the paired Wingard, Han, Call, and Zou rows per §3.10, and the unresolved canine saphenous-vein candidate is recorded as a failed search rather than dropped or fabricated per §3.11. The history.yaml entry is append-only with actor/reason per §3.14, and the new evidence carries reviewState ai_extracted with humanReviewed: false — nothing presents itself as ratified. The only soft spot is E019's title ('never been measured in any arteriole'), which is punchier than its own qualified body, but the record's limitations state the coverage boundary explicitly, so this is ordinary editorial latitude, not miscalibration. No checks are weakened, no AGENTS.md edit, no confidential material.
