From 5dd70923066c0534bfe2e7bfa73213350232a70d Mon Sep 17 00:00:00 2001 From: Alex Moskowitz Date: Wed, 29 Apr 2026 23:30:18 -0400 Subject: [PATCH 1/3] docs + ci: README post-merge accuracy and tighter ROBOT triggers README review pass after the IAO + RO promotion: 1. Update the headline framing (line 9) to acknowledge that BFO, RO, and IAO are now full upstream imports rather than just calling out BFO + CCO. 2. Update the certificate sample's "ENTAILED TRIPLES ADDED" from the previous stub-state value (+3473) to the current full-imports value (+47888) so the advertised proof matches what the pipeline actually emits. 3. Update the "Getting started" section's asserted-vs-post-reasoning numbers from the stub-state baseline (1434 -> 4907) to the current values (17266 -> 65154) and explicitly note that this is over the full BFO + RO + IAO + ARCO union. ROBOT validation workflow trigger tightening: - Drop push triggers on tooling/** and experiment/**. With the full-import HermiT step taking ~30-40 minutes, running it on every WIP commit is noisy without adding signal. Independent DL verification still runs on every push to main and every PR targeting main, which is exactly what the README has always promised. Manual workflow_dispatch is retained. No ontology, gate, SHACL, SPARQL, or pipeline-logic change. Documentation accuracy and CI ergonomics only.

"Where do all those derived triples come from?" The overwhelming majority is OWL-RL closure over upstream axiomatization (BFO upper-level subclass propagation, RO property chains and inverses, IAO ICE hierarchy), not ARCO-specific reasoning. Slim MIREOT modules would shrink the post-reasoning graph by roughly an order of magnitude without changing the classification outcome. 2. "What does this mean for adding a new Annex III category or peer regulation?" Full imports leave whatever BFO/RO/IAO terms the new category needs already in scope; the only engineering work is the new gate axioms and ARCO-side classes. MIREOT modules would add a per- addition module-rebuild step that tends to rot if forgotten. Documentation only; no code or ontology change.
