# Grid 2.0 Standards Documentation

> Normative reference for the Grid 2 overlay plane: G2P, GCAP, and DESP, plus member behaviors, allocation domains, failsafe rules, and the G2TF comment cycle. For implementers, utilities, and editors working from the living specs and RFC #1.

## Pages

- [Overview](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/01-overview.md): What the Grid 2 overlay plane is, who implements or comments on it, the three-protocol stack, and the first docs routes after RFC #1.
- [How to read the specs](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/02-how-to-read-the-specs.md): Status headers, RFC 2119 keywords, living files versus immutable RFCs, independent 26.x lines, and what Draft seeking input still leaves open.
- [Minimum viable domain](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/03-minimum-viable-domain.md): Smallest Grid 2 domain: one host utility plus one flexible load, transmission-owner constraint provisioning, and the connect-and-manage on-ramp.
- [Overlay and Grid 1](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/04-overlay-and-grid-1.md): Overlay membership without a perimeter, NERC/FERC/TSO non-interference, coordination without prices, and v26.0 energy-in-the-interval scope.
- [One-minute window](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/05-one-minute-window.md): One-minute interval clock between ~5-minute market dispatch and sub-second ancillaries, commit-before-open, and the Grid 1-prevails conflict rule.
- [Allocation domains](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/06-allocation-domains.md): Nested constraint domains, transmission-owner authority, voluntary membership by spec compliance, and commercial terms that stay outside the protocol.
- [Service classes](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/07-service-classes.md): DESP classes A, B, and C above Grid 1 Firm, curtailment order C then B then A, Firm/Semi-Firm/Flex aliases, and per-interval reclassification.
- [Failsafe model](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/08-failsafe-model.md): No-surprises fallbacks per element, interval-only commitments, pool ramp limits, and fallback that is locally determinable without a remote peer.
- [Federation](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/09-federation.md): Allocator announce-and-listen, nested local-to-regional domains, missing-announcement conservative clearing, and partition that does not trip unrelated members.
- [Run Phase 0 shadow mode](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/10-run-phase-0-shadow-mode.md): Phase 0 dry-run: exchange and track commitments, execute only the Grid 1 baseline, then graduate to Phase 1 local integration and Phase 2 federation.
- [Map workloads to classes](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/11-map-workloads-to-classes.md): Informative Flex 0–3 and ERCOT CLR/PCLR mappings onto DESP A/B/C, plus what the Allocator never sees inside a facility.
- [Provision constraint inputs](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/12-provision-constraint-inputs.md): Required Grid 1 constraint set, optional DLR and distribution-factor inputs, input digests, and the rule that peer announcements must not relax local limits.
- [Comment, review, and file errata](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/13-comment-review-and-file-errata.md): Discussions versus Issues versus PRs, RFC #1 errata label, two-editor review, RFC 2119 and compatibility statements, and decision-log recording.
- [G2P reference](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/14-g2p-reference.md): Element identity, four message families, one-minute timing, authenticated descriptors and commitments, stale-commitment faults, and unspecified wire format.
- [GCAP reference](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/15-gcap-reference.md): Clearing inputs, headroom-then-buffers-then-tiered-curtailment, per-class commit outputs, identical-input determinism, and pool and ramp-safety bounds.
- [DESP reference](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/16-desp-reference.md): Class table and semantics, mandatory C-B-A curtailment order, domain class-policy limits, and open naming, extensibility, and SLA items.
- [Use Member](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/17-use-member.md): Per-class consume positions, commit-% listen, edge workload mapping, self-dispatch and telemetry MUSTS, ramp limits, and firm-limit fallback.
- [Buffer Member](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/18-buffer-member.md): Signed charge and discharge offers, committed dispatch before any load curtailment, verified self-dispatch, SoC open items, and standalone Grid 1 schedule fallback.
- [Source Member](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/19-source-member.md): Supply offers over a forward vector, committed take, forecast-error open items, v26.0 single-class supply, and Grid 1 interconnection fallback.
- [Allocator](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/20-allocator.md): No-discretion deterministic clearing, constraint-authority inputs, federation announcements, withhold-on-stale, and whole-pool ramp sizing.
- [Document lifecycle](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/21-document-lifecycle.md): Draft to Proposed to Stable to RFC, YY.N protocol versions, required compatibility statements, and the GOVERNANCE.md decision log.
- [Contributing](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/22-contributing.md): Open individual participation, comment-cycle steps, RFC 2119 and one-sentence-per-line conventions, and implementation reports from Phase 0 onward.
- [Governance and licenses](https://grok-wiki.com/public/docs/g2tf-org-g2tf-standards-436ba3f3e0ff/pages/23-governance-and-licenses.md): Editor, contributor, and Task Force roles; rough consensus; CC BY 4.0 spec text and Apache-2.0 code; trademarks; and Grid 1 regulator relationship.
