SMILE — Sustainable Methodology for Impact Lifecycle Enablement (v6.4.5): Operational Grammar for Auditable, Shared and Forkable Reality
Version 6.4.5 makes the one-page methodology overview readable. In v6.4.4 the figure was 1999 pixels compressed into a 6.6-inch text column — about 303 dpi, roughly 4-point type — and was attached separately, so the record opened on the image rather than the paper. Here the figure is given its own landscape page at full width, and six panels cut from it are repeated inside the sections they explain: the scale axis in 2.4, the AI Journey in 4.4, the Spin Twin Lifecycle in 4.7, the Outcome-to-Data chain in 5.2, the Alignment row in 5.5, and the Cycles and Use Cases rows in 6.1. Each panel lands between 75 and 154 dpi, so its smallest labels are two to four times larger than before. Banner sentences that span the full width of the figure are quoted verbatim in the panel captions rather than cut across panels. The overview is no longer a separate attachment; it is part of the text. No claim, reference or figure other than the overview is changed from v6.4.4. Version 6.4.4 restored the one-page methodology overview to the front of the paper, immediately after the abstract. The overview predates this specification: it was drawn approximately four years earlier in work with manufacturing industry, and it is the artefact from which the phase sequence, the cycles and the parallel AI journey in this paper descend. It is reproduced unchanged and is therefore not fully industry-agnostic; where its wording differs from the specification, the specification governs. SMILE (Sustainable Methodology for Impact Lifecycle Enablement) is a lifecycle methodology and design-science specification for constructing continuously learning digital twins as a consequence of impact-first project work. Version 6.4.x adds the operational grammar for auditable, shared and forkable reality: the Reality Branch Lifecycle ("no simulation becomes history"), the Reality Consensus Protocol, a canonical metamodel mapped to PROV-O, SOSA/SSN, OWL-Time, GeoSPARQL, ODRL, SHACL, NGSI-LD, ISO 23247, OpenUSD, MCP and A2A, an applicability and proportionality instrument, a spatial business and operating model, virtual-world rights and governance, a measurement framework, and fourteen falsifiable research propositions. The paper reframes Tuckman's group-development stages as concurrent capabilities on a shared reality substrate (grounding, situated contestation, protocolisation, closed-loop action, reconstitution), introduces Recorded Reality, the Epistemic Horizon, Reflexive Zoom, Reality-Defined systems, SEEN (Situation, Evidence, Effects, Needs) and the digital twin as a constitutional obligatory passage point. Version 6.4.3 completes an exhaustive verification of all 153 references, redraws the metamodel and proportionality figures, and adds an archival deployment record (2022) as lineage evidence. Note: the acronym expansion changed from "Interoperable" (v5.x) to "Impact" (v6.x); see the version history in the manuscript.
