A.6.3.NAR:5.1 - Scientific mechanism narrative
A chemistry paper has calculations, candidate mechanisms, failed synthesis attempts, and an unresolved tension between theory and experiment. For an internal explanation, the first useful result is a discovery-ordered account: failed attempts, structural clue, revised mechanism, new experiment, remaining uncertainty. Its compact note says that candidate relations and failed attempts are preserved, full calculations are deferred, connective claims are not proof, and mechanism-proof use returns to the calculations and experiment record.
If a published account must travel independently, be cited or disputed as a stable account, or support consequential reliance, open the exact branch. Mere publication of a source-linked low-reliance explanation does not require it. Source episteme ChemistryMechanism-X states the relevant claims about the reaction case; receiving episteme ChemistryDiscovery-Y concerns the same case. DiscoveryNarrativization : X -> Y records the exact selection, scheme relation, discovery order, preserved and lost claims, prohibited proof overread, and return. Calculation files are not X; the paper form and carrier are not Y.
