Refresh wiki for August–September 2026 ecosystem cycle

[geoffturk]

Four things happened since the August refresh that the wiki either contradicted or did not know about: the Dogwood coordinated release (2026-08-30, tag-only, re-cut as Dogwood-R1 two days later) and the first Eucalyptus RC (2026-09-17); the DTG Core Credentials spec tagging Working Draft 02 (2026-09-07) with its main branch already heading for 0.4.0; the sysop "deploy" stream the wiki had called "coming soon" shipping as three open-source VTA Farm repos; and data rooms landing in the VTI as a third kind of node. WD02 is the disruptive one: it deletes the four-way DID taxonomy the concept pages were built on and adds two credential types, so the pages described a spec that no longer exists.

Spec-driven changes (WD02 and the post-WD02 main branch):

• New concepts/correlation-scope.md — the holder-declared pairwise / directed / public width that replaces the DID types. did-types.md is rewritten as a retired/history page explaining why the taxonomy went and pointing at its replacement.
• New concepts/delegation-credential.md (VDC, third edge type) and concepts/authority-credential.md (VAC, attenuable permission chains).
• New concepts/statement-credential.md (VSC) for the main-branch folding of endorsement and witness into predicate profiles; clearly marked as not yet tagged or implemented anywhere.
• membership-credential.md: the grant + consent-carrying acknowledgement pair is now fully specified and implemented.
• witness-credential.md, credential-categories.md, dtg-credentials-overview.md and the other credential pages moved to digestMultibase and the WD02 category layout.
• entities/dtg-credential-spec.md rewritten for WD02 with the PR-by-PR history; entities/dtg-credentials.md covers the eight breaking releases (0.2.0 → 0.9.1) that tracked it.

New pages for sources not previously covered:

• entities/vtafarm.md, entities/vtafarm-api.md, entities/vtafarm-k8s.md — the portal, the Go/Kubernetes provisioning backend and the OpenTofu cluster on Hetzner, with the namespace-per-user / Vault-sealed-seed security model.
• concepts/data-rooms.md — credential-governed, MLS-encrypted shared spaces with their own DIDs and no member list.
• concepts/post-quantum-cryptography.md — ML-DSA keys in the VTA, hybrid multi-proof credentials from the VTC, and the PQ path in the TSP implementation, with the VID model noted as not yet PQ-aware.
• concepts/peer-identity-vetting.md — early, marked as such.

Entity and concept activity refreshed through mid-September: coordinated-releases.md gains the Dogwood / Dogwood-R1 / Eucalyptus RC-1 version matrix; trust-spanning-protocol.md covers the Rev 3 flag day and the five-implementation conformance suite; verifiable-trust-infrastructure.md, verifiable-trust-agent.md, affinidi-tdk.md, affinidi-webvh-service.md, didwebvh-rs.md, openvtc.md, vta-browser-plugin.md, vti-didcomm-js.md, rp-sdk-js.md and verifiable-git-infrastructure.md pick up the security sweep, the wallet console and persona map, and the Signed-by-DID: trailer. vti-setup.md follows the explore stream to VTI-Dogwood and the newly verified bootstrap script.

Two things a reviewer should notice: the dtg-credentials digest- encoding divergence recorded as unresolved last cycle is now closed (the crate and the spec converged on multibase), and the per-repo version matrix flags several components whose main branch is ahead of any tag — those are recorded as "not yet tagged", not as releases.

overview.md, index.md (ten new pages) and log.md updated to match.
