What changed in this version
For readers who saw an earlier draft, these are the main changes since version 6.
| Item | What happened | Why |
|---|---|---|
| Adjacent fields and new evidence (v7.9) | Telephone engineering added to the discipline's lineage. New evidence from supply chains, power grids, risk management and AI platforms. It covers why not to split a shortage pro rata, why to name shared drivers, and measured AI demand. One labeled exploration on AI demand declared as a policy. New sources are listed as [A1]–[A9] until the next renumbering. | To test the method against fields that solved neighbouring problems first |
| Credit, re-checked (v7.8) | More of the frame is credited to Hixson and Guliani: blow-up factors as an early α, the fast lane, one plan for several products' upside, and the limits small companies face. The 2026 SRE chapter's link to error budgets is quoted again, and its stockout resiliency is named. Several reference links were repaired. | So a reader can tell which parts are the sources' and which are this paper's. |
| Prior art, re-checked (v7.7) | The measuring loop's eight steps are labeled as this paper's arrangement of the 2026 SRE chapter's advice. A few readings of the chapter were softened, and Hixson and Guliani's "costs" are read as an early form of the coefficient | Accuracy and fair credit |
| Softer where experts push back (v7.7) | Coefficients as a straight-line reading near today's load; k set per cell, with uneven failover; the marginal job pulls the next buy earlier; buffers multiply only if latency must hold during a failure | Precision |
| Layers | An abstract, an executive summary and a one-page version now come before the deep dive | Each reader can stop at the depth they need |
| Two claims and a method | The paper now states two claims, that a coefficient is an agreement and that approval is not allocation, and offers one method | To say plainly what it argues and what it offers |
| The commit-point method (Section 8) | New: eight steps for one launch, what each side owes the other, and a walk-through | To give planners something to try, not only an argument |
| Supply (Sections 6.2 and 6.7) | Section 6.2 rewritten around public values; Section 6.7, on supply's own step changes, expanded | Supply runs on its own clock, with its own lead times and contracts |
| Appendices A and B | New: a worksheet with a full walk-through, and the public record on supply | Each can be printed or handed over on its own |
| Figures | Added throughout: clocks, scenes, method cards, flowcharts, swimlanes and charts of public values; 60 in all | So the figures and captions carry the argument on their own |
| Corrections | Hixson and Guliani's five years is quoted in full, as their example, not a maximum; the AEP Ohio tariff figures and the Section 9.1 quote are corrected | Accuracy |
| Tests on the mechanisms (Section 9.2) | Each test moved from Section 9.4 to the mechanism it belongs to, under You'll know it's working when… | So each mechanism carries its own check |
| Mechanism 3 | Renamed the coefficient register and versioned rate card | It's the practice that keeps the first claim true, not a second statement of it |
| Sentences | Most long sentences split into shorter ones; a few that hold quotes are left whole | Easier to read |
| The 2026 SRE chapter | Read in full; credited in Sections 1, 3, 5.2, 5.4, 6, 7, 8.5, 9, 10, 11, 12 and 13, the Terms and Appendix B.5 wherever it got there first, and every "may cover" resolved | Its authors include Hixson, and much of this paper's ground is theirs first |
| New public sources | Added on pooling, stranding, quota versus capacity, phased supply, the Meet case and recent operator statements; lineage of the discipline in Section 3 | Each supports a claim already made, or softens one |
| Eight explorations | Labeled ideas from setting the paper beside the SRE chapter (Sections 5.2, 6.3, 6.6, 6.7, 9.3, 10.2, 12 and 13) | Offered as ways to think, not findings |
| The measuring loop (Section 5.2, Figure 10) | The SRE chapter's business-driver loop is now laid out step by step and credited in full; the paper adds the price reading and a labeled idea that the chapter's two alerts route each term to its owner. A second labeled idea makes re-baselining a routine step that scores the gap by owner. Sections 5.4 and 7 each gain one line | The paper's loop showed only the governance half |
| The handshake (Section 10, Figure 41) | Section 10 opens with capital, supply and demand as a handshake the planner brokers, and what the planner trades in; Figure 41 becomes the triangle, with the three seams on its edges | The people half lacked one frame |
| People practice (Sections 6.1, 6.4, 9.1, 9.3, 10.1, 10.2, 10.4, 12 and 14) | Short, general notes on where the right to refuse comes from, talking before the intake, no surprises in the room, shocks, finance's distrust, translation, freezes, onboarding, work between charters, re-baselining, brokering and re-shaping | Practice the mechanisms depend on, written as practice, not as a story |
