Jan-Peter von Hunnius 41f1ec2887 openup: EA model preparation (COD) - checklist, scripts, realizations intermediate 
Per design-wi-2-architecture-cleanup.md §11.b/c: keyfob-station pipeline
studied (add-wi19-uc11.ps1, export-model-json.ps1). Platform gap: EA COM
pipeline is Windows-only; this session ran on Linux (no EABase.eapx found,
no pwsh) - .eapx skeleton NOT committed, documented in model/README.md
with the two path options. Landed:
- docs/openup/model/BUILD-CHECKLIST.md: full EA-session checklist
  (packages, 3 actors, 12 UCs with scenarios, 13 associations, 12
  realization packages / 36 elements) derived from use-case-model.md +
  uc-realization-mapping.md
- docs/openup/model/README.md: platform note, status, drift rule
- docs/openup/model/exports/uc-realizations.json: generated from mapping
  §2 via scripts/openup/markdown-to-json.py (tested locally)
- scripts/openup/build-model.ps1, export-model.ps1: adapted from keyfob
  patterns, Windows-gated (human gate per design §11.d)
- scripts/openup/markdown-to-json.py: local markdown -> JSON transform

docs/openup/model/ — EA Model Home (WI-2 status)

Per design-wi-2-architecture-cleanup.md §11 (decision reversal 2026-10-03): the binary EA model lives here at skara-brae.eapx with generated exports under exports/; generator scripts live in scripts/openup/ (repo root). Markdown stays the content source of truth; exports are generated, never hand-edited.

Status after COD session 2 (2026-10-03, Linux agent)

Design item (§11.b/c) Status
§11.b.1 clone keyfob-station read-only done — studied add-wi19-uc11.ps1 (scenario embedding: Name/Type/Notes/Steps arrays with per-step Actor) and export-model-json.ps1 (COM walk → JSON); patterns reused in the scripts below
§11.b.3 .eapx skeleton from EA's EABase.eapx not done — platform gap. No EABase.eapx exists on this Linux machine (searched ~, ~/.wine, /mnt, /media, /opt, /usr/local); EA is a Win32 application. The binary is deliberately NOT committed and NOT derived from keyfob's model (it carries keyfob content). Copy it during the Windows session (see BUILD-CHECKLIST §0).
§11.b.4 build checklist done — BUILD-CHECKLIST.md (packages, actors, use cases, scenarios, associations, realization packages — complete and clickable)
§11.c build-model.ps1 / export-model.ps1 committed, adapted from the keyfob patterns; Windows-gated — this machine has no EA COM automation (and no pwsh), so they could not be executed here. They are prepared, not proven.
§11.c machine-readable intermediates exports/uc-realizations.json generated (by scripts/openup/markdown-to-json.py, tested locally) from mapping §2 — 12 realizations, 36 elements. exports/use-case-model.json is not generated here: the markdown carries no per-step actor tags, so a faithful JSON intermediate cannot be produced mechanically. Per §11.c's recorded fallback, build-model.ps1 embeds the scenario content as PowerShell arrays (keyfob pattern); the human gate verifies it against use-case-model.md via the checklist.

Linux constraint and the two options

The EA pipeline is PowerShell + COM automation (New-Object -ComObject EA.App) against a .eapx (MS Access/Jet) file — Windows-only. This session ran on Linux. Options:

  1. Run the pipeline on the Windows/EA machine (planned path). BUILD-CHECKLIST.md §0–§5 is the session script: copy EABase.eapx → skara-brae.eapx, run build-model.ps1, verify per checklist §4, run export-model.ps1, commit .eapx + exports/ + scripts/openup/ as openup: EA model WI-2 baseline.
  2. EA manual XML export → agent-side transform. If the COM scripts hit friction in EA, export the package manually from the EA UI (Publish → XML / XMI), drop the file into exports/, and the agent side can transform/validate it into the JSON intermediates with a small local script (same role as markdown-to-json.py). The committed scripts remain the reproducible path of record.

Drift rule

Markdown (use-case-model.md, uc-realization-mapping.md) and the model must agree; exports are generated; a mismatch is a defect fixed in the same cycle (stale docs are defects). The human gate (design §11.d) owns .eapx editing/verification — never the agent.
