v0.13.0 — Tabular Editor cleanup script alongside the AI prompt

[jonathan-pap]

Summary

v0.12.0 shipped an AI prompt for users who run cleanup through Claude Code with the pbi-desktop plugin. Many BI devs live in Tabular Editor instead — v0.13.0 generates a paste-into-TE C# .csx script as a second output format from the same audit data, no AI loop required.

Same input (FullData + category), same filtering (EXTERNALMEASURE proxies + auto-date excluded, Stage 1 / Stage 2 ordering), different output. The two formats serve different users; both ship today.

What changes

Surface	Change
Modal	New segmented toggle at the top: AI prompt (.md) | Tabular Editor script (.csx). Body, hint text, and download button label switch in place when toggled.
CLI	--format ai-prompt | te-script flag added to powerbi-lineage prompt. Default is ai-prompt, fully backwards compatible with v0.12.0. Unknown values fail loudly.
Improvements MD embed	Unchanged — AI prompt only. TE users live in TE, not in the wiki.
Unused-tab toolbar button	Unchanged — opens modal; user toggles format inside.

Script anatomy

The TE script (works in both TE2 free and TE3 paid):

1. Hardcodes the target list as anonymous-type entries { Table, Measure, Stage } — C# 3.0 syntax, portable across every TE version.
2. Iterates with safety guards: missing table → skip · missing measure → skip (idempotent) · EXTERNALMEASURE in expression → skip (defence-in-depth on top of the static filter).
3. Calls m.Delete() only after all three guards pass.
4. Prints a tally and reminds the user to Ctrl+S — TE doesn't auto-save.

Tests

• 311/311 pass (was 299): 9 new for the TE-script generator (header, target entries, EXTERNALMEASURE static + runtime, Stage ordering, auto-date exclusion, no-op empty case, C# string escaping, trailing newline, Ctrl+S reminder), 2 new CLI cases for --format.
• No new runtime dependencies.

Test plan

Automated (already green locally):

• npm test — 311/311
• npm run build — clean
• Inline-script parse-check on the generated HTML still passes

Manual (defer to merge / pre-tag):

• Open a real .pbip with the dashboard. Confirm modal opens in AI-prompt view by default. Toggle to Tabular Editor script — body, hint, download button label, and filename extension all switch. Toggle back — same.
• Download .csx. Paste into TE2 or TE3 Advanced Scripting tab. Press F5 against a sacrificial model. Confirm the listed measures get deleted (and EXTERNALMEASURE-bound ones, if any, get skipped with the runtime guard).
• CLI: node dist/app.js prompt --category measures-all --format te-script --report <path> emits a script. --format omitted defaults to the markdown prompt (backwards compat smoke).
• Re-open the project in Lineage after running the script — confirm the audit shrinks.
