Since Sep 26, 2025 we focused on tighter FedWiki ↔︎ DM6 Elm integration and a smoother embed/debug loop. The FedWiki importer was rewritten to create one topic for the page title and one per story item with non-empty text (using a simple `{ typ, text }` decoder), and to add all new topics to the current map; this replaces the old paragraph-only import and avoids empty labels. AppRunner logging and naming were cleaned up while keeping the same behavior.
On the embed side, we introduced a small “Cold Boot” console that mounts DM6 Elm via `AppEmbed` inside a wiki frame, boots from either the page JSON or `{}`, and pipes the same JSON through jq for quick inspection. We also added one-liners to stack an Elm Debugger iframe under (or beside) the app and redirect `window.open` so the debugger appears in-page, which has made iterative testing far quicker. Open questions: rendering “Monad label-only” topics as true SVG circles (currently CSS-rounded divs) and polishing the frame/plugin interactions. The code up to commit 5cea616e advances import fidelity, embed robustness, and on-page debugging without changing the main document app. commit 
--- # 2025-09-27 → 2025-09-29 — FedWiki containers, WhiteBox rendering, and import flow ## Highlights * **FedWiki containers now render as *WhiteBox* by default in the embedded app**, fixing the “stays a label until interaction” issue. Also tightened the import + renderer handshake and touched up the dev shell. ([GitHub][1]) * **Structured FedWiki import**: create title container in the current map, ensure a child map, and import story items in order. ([GitHub][1]) * **Renderer + model glue**: detection helpers for “this topic is the FedWiki page”, safer `currentMapId`, and a fallback label-only circle renderer for monads. ([GitHub][1]) * **ModelAPI hardening**: `addItemToMap` becomes the single guarded entry; root map + `mapPath` correctness tweaks. ([GitHub][1]) ## Commits (newest → oldest) * **fix(renderer, import, devshell): render FedWiki container as WhiteBox; …** — `4f4412b` (2025-09-29) Makes the FedWiki title container show as WhiteBox on first paint; includes minor import + shell polish. ([GitHub][1]) * **feat: Ensure FedWiki containers render as WhiteBox in embedded app** — `b0447a4` (2025-09-29) Forces WhiteBox for the detected FedWiki container in the embed flow. ([GitHub][1]) * **feat(fedwiki): implement structured container tracking and WhiteBox rendering** — `053edd4` (2025-09-29) Adds the structured “this is the FedWiki page container” metadata used by the renderer. ([GitHub][1]) * **fix: handle empty mapPath gracefully in currentMapId** — `92a0fde` (2025-09-29) Removes a source of flakiness when the app boots without a full `mapPath`. ([GitHub][1]) * **feat(fedwiki): implement nested page structure with container tracking** — `e72951c` (2025-09-29) Solidifies child-map creation and container bookkeeping. ([GitHub][1]) * **feat(fedwiki): add ensureChildMap and Id-based page-container detection** — `b8d88c0` (2025-09-29) Introduces helpers used by the import and renderer to tie the title to its child map. ([GitHub][1]) * **feat(map): add FedWiki page detection helpers and …** — `de93b27` (2025-09-29) Renderer-side detection utilities for FedWiki containers. ([GitHub][1]) * **feat(map): render `Monad LabelOnly` as SVG circles with native drag** — `b90dd9b` (2025-09-28) Improves the minimal label-only topics and keeps free-form map editing snappy. ([GitHub][1]) * **feat(fedwiki-import): use currentMapId and import story items** — `5cea616` (2025-09-27) First pass that imports story items beneath the created page container in the current map. ([GitHub][1]) * **fix(modelapi): make addItemToMap the single guarded entry; …** — `5eae3f9` (2025-09-27) Centralizes map mutations through one safe path. ([GitHub][1]) * **fix(main): ensure root map and valid mapPath; correct Rectangle fields** — `5e69c39` (2025-09-27) Stabilizes initial model + geometry so early renders don’t glitch. ([GitHub][1]) ## What this delivers * **Immediate WhiteBox** for the FedWiki page container (no click/drag needed). * **Deterministic structure**: the page title gets a child map, and story items land there in order. * **Safer boot**: fewer edge-cases around `currentMapId`/`mapPath`, better first render. * **Editing unchanged**: non-FedWiki containers keep the free-form map behavior. --- [1]: https://github.com/RalfBarkow/dmx-systems-dm6-elm/commits/main/ "Commits · RalfBarkow/dmx-systems-dm6-elm · GitHub"
