docs: add warm dev loop proposal (mxbuild --serve + reload_model)#1
Merged
Conversation
Draft proposal covering two scenarios: a Docker-free `mxcli dev` warm run loop to replace the docker inner loop, and an iPad split-screen preview workflow (Claude Code Web + browser, preview-before-commit). Built on measured mxbuild --serve incremental builds (~0.8s warm vs ~30-60s one-shot) and the runtime reload_model hot-reload primitive (~0.1s, no restart), with restartRequired branching page/microflow from entity/DDL changes.

Frame the iPad scenario as one leg of the full journey: Claude design prototype -> Mendix model via mxcli/MDL -> production security (ALTER PROJECT SECURITY LEVEL PRODUCTION, per-role grants) -> live warm-loop testing under real security, all on iPad without Studio Pro.

…loop proposal Verified reload_model reloads model store + microflows + i18n only, not the datastorage/entity layer. The runtime reconciles its metamodel catalog (mendixsystem$entity/entityidentifier/attribute/association) at startup, so entity/view-entity/association changes need a restart. Confirmed directly: a view entity added via reload_model never appears in mendixsystem$entity. Adds the two-signal decision matrix (restartRequired x get_ddl_commands) and the key nuance that OQL view entities need restart WITHOUT DDL (query-time, not materialized). Notes the standalone boot lacks preview_execute_oql for functional OQL verification.

…warm-loop proposal One static hub fronting many dynamic dev containers, verified via chisel: - chisel fan-in (one server, many clients on distinct ports; --authfile isolation) - why chisel works where ngrok/cloudflared/localtunnel didn't (go install past the gate, single-443 multiplex, system trust store already holds the MITM CA) - mxcli tunnel-hub (static) + mxcli dev --hub (self-registering dynamic side) - registration flow over chisel's authfile-reload + client-declared-remote primitives - admin overview page: fleet list + per-container pending-change summaries - Mendix fleet wrinkles (subdomain ApplicationRootUrl, cookie/DB isolation, slots) - reclassify coupling Option D (live tunnel) from "not recommended" to verified/preferred for the multi-container dev loop, artifact-push kept as durable fallback Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JXnEgoc2NQP1Y2TWMCMXC4
…strap) How a user goes from a new Claude Code Web project to a running testable app: - entry points: mxcli new (new app) / clone + mxcli init (existing) - gap identified: init scaffolds a devcontainer + .claude tooling but no SessionStart hook; Claude Code Web reaps Postgres/JVM on idle, so it needs an idempotent `mxcli dev up` wired to SessionStart - dev up = setup mxcli/mxbuild/mxruntime (all exist) + Postgres + boot + serve - first-run vs warm cost table; heavy costs are one-time and image-cacheable - adds impl rows (dev up, init SessionStart hook) and an open question on image pre-baking + the SessionStart contract Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JXnEgoc2NQP1Y2TWMCMXC4
Restructure Provisioning into three entry points (prompt template primary for web/iPad, repo template, local CLI). Add the prompt-template subsection with: - the draft bootstrap prompt - rule 1: committing the config is mandatory (survives reaping; produces the repo-template end state without a maintained template) - rule 2: mxcli delivery is an environment-layer concern (github gate blocks release curl; go install works only for a public module) - proven via chisel Adds impl rows (new --emit-template, shipped prompt template, public-module/ env-preinstall delivery) and open question 12 on mxcli delivery into a gated empty repo.

Keep one proposal but show how to ship it incrementally as four independent, value-ordered slices: (1) warm local loop, (2) provisioning, (3) single-app external preview, (4) tunnel hub. Recommends 1->2 first (solo dev, no external parts), 3 for single-app preview, 4 as a separately-reviewed scale-out.

Ran scripts/gen_proposals_readme.py. Indexes 5 previously-missing active proposals: mxcli_dev_warm_loop, check_mxbuild_gap_heuristics, ai_capability_dataset, architecture_graph_visualization, playwright_session_reuse. Side effect, flagged: PROPOSAL_marketplace_modules (status: shipping) and UNIFIED_SCHEMA_REGISTRY (status: descoped) drop from the index because their statuses are non-canonical; the generator only buckets canonical statuses. They remain on disk and re-index once their statuses are normalised (maintainer's call — not changed here).

Lint category-2 fix (maintainer-approved) so both re-appear in the index: - PROPOSAL_marketplace_modules: status shipping -> partial (active); tidy date - UNIFIED_SCHEMA_REGISTRY: status descoped -> abandoned; git mv to archive/ (terminal status belongs in archive/; retired into engalar's codec) Regenerated README via scripts/gen_proposals_readme.py: marketplace now under In Progress, UNIFIED under Archived, warm-loop still indexed. No proposals dropped from the index. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JXnEgoc2NQP1Y2TWMCMXC4
Document the first-part research (mxcli check improvements) as a proposal:
- where Mendix's diagnostics catalog lives (Mendix.Modeler.Texts.dll PO files)
- structure: CODE__SUMMARY msgids, {param} templates, severity via CE/CW/CI
prefix, LOCATION + MX_DOCS_CAT tags
- findings: 1318 codes (11.12.1), static-checkability tiering, mxcli already
reimplements ~77-81, mx check is same-floor as a build (Go check is the only
speedup)
- approach: versioned data asset, port by tier/frequency, harvest-against-oracle
- verbatim examples (small fair-use sample)
Commit scripts/extract-diagnostics-catalog.sh (the methodology). Its OUTPUT is
Mendix's proprietary corpus and is NOT committed (see IP open question).

…lope is mxbuild-only End-to-end reproduction of the mendixlabs#600 stack (DW 3.10.0 over bundled 3.4.0 in an 11.12.0 project, DataGrid2 authored with mxcli, isolated from the Atlas template pages) with an order-independent, ID-masked before/after-update-widgets subtree diff proves the parser/template/augment approach is structurally capped below large version jumps: - Nested-column PropertyKey sets are already identical before/after (augment adds every new 3.10.0 key correctly). - Residual drift is dominated by fields ABSENT from the widget XML source: AllowUpload (x105), DesignProperties, LabelTemplate, and a mxbuild-COMPUTED Required (XML declares 3 required="true"; mxbuild emits 54). - update-widgets on the same copy takes the grid CE0463 -> 0. Since these fields are not derivable from the .mpk, no augment (including the proposed full-ValueType path a) can reproduce a version-faithful WidgetType. A speculative reconcileValueTypeSchema was implemented and reverted (setting Required from the XML attr would mis-set the 51 computed keys to false). Revised path forward: delegate the envelope to mxbuild's own update-widgets made v2-safe (adopt mendixlabs PR mendixlabs#764), keep the moderate-drift augment as-is. Records the rejected approach inline in augment.go and updates the proposal Open Question #1.

…LVED via editorConfig extractor Updates Open Question #1 to record the landed outcome (was still framing the instance last-mile as needing v2-safe update-widgets / a goja spike): - The static editorConfig.js extractor (4b8c4f5) + selection-value fix (666a65b) close the DataGrid2 CE0463 natively in mxcli — 0 errors on the mendixlabs#600 stack (11.12.0 + DW 3.10.0), minimal and full, no bundled regression. No mxbuild/ update-widgets dependency needed for DataGrid2. - Phase 2 (458c52a): extraction moved into .def.json generation; rules wired into check as the config-aware MDL-WIDGET10 warning. - Marks paths (c) update-widgets and (d) goja as superseded (c kept as fallback for widgets the static extractor can't fully lift); records coverage (9/28 DataGrid hide-calls) and the JS-AST / LLM-property-card follow-ups.
