[0.5.0] — 2026-04-18 · Stop 6 — composite-model fixes (branch stop-6/composite-model-fixes)

Closes every known gap the Health_and_Safety composite-model fixture exposed. Four discrete fixes, each with its own regression test, plus a new auto-date toggle in the Tables tab.

Fixed

• Task 6.1 — Multi-line TMDL expressions with quoted names parse correctly. The expression 'NAME' regex used \S+ for the name, which stopped at the first space inside quoted identifiers like 'DirectQuery to AS - Health_and_Safety_Gold'. Every composite model silently parsed zero expressions, cascading into every DQ partition collapsing to "Unknown / M". Switched to '[^']+'|"[^"]+"|[\w.-]+ so quoted names are captured.
• Task 6.2 — Entity-partition source resolution via shared expressions. TMDL composite partitions use source + nested entityName: … + expressionSource: 'NAME', not inline M. The previous extractor only handled the source = <inline M> form. extractTmdlPartitions now accepts an expression table, follows expressionSource references, and runs inferSource against the resolved body. Result on H&S: 48 DQ partitions previously "Unknown / M" now resolve to Analysis Services with the real cluster URL (powerbi://api.powerbi.com/…). The partition-name regex was also fixed to handle quoted names with spaces (partition 'Date NEW' = entity).

Added

• Task 6.3 — Structured externalProxy field on ModelMeasure. EXTERNALMEASURE proxy detection moved from render-time regex into buildFullData, populating { remoteName, type, externalModel, cluster }. cluster resolves from the corresponding shared expression's AnalysisServices.Database(...) first argument. Downstream consumers (dashboard lineage card, measures MD export, future Quality rules) now read a structured field instead of each re-implementing the regex. Client keeps the render-time regex as a back-compat fallback for older DATA payloads.
• Task 6.4 — origin: "user" | "auto-date" on TableData. Tables matching LocalDateTable_* or DateTableTemplate_* are tagged as auto-date infrastructure. The client hides them from default counts on the Tables tab, Sources tab, and tab-count badges. A toggle button in the Tables-tab footer ("Show auto-date (N)" / "Hide auto-date (N)") opts them in. Default tab-count footer notes +N auto-date hidden so the count difference is discoverable.
• tests/composite-model.test.ts — 5 integration tests against the real H&S fixture covering every task above:
  1. expressions with quoted names parse
  2. every DQ partition resolves to Analysis Services
  3. EXTERNALMEASURE proxies get structured externalProxy
  4. proxy cluster URL resolves from the shared expression
  5. auto-date classification matches the naming convention exactly Tests gracefully skip if the fixture isn't checked out.

Test results

54 / 54 green (was 49, +5). Typecheck and build clean. Live smoke against test/Health_and_Safety.Report:

• 53 tables total → 43 user + 10 auto-date
• 48 DQ partitions resolve to Analysis Services (was 0 before)
• 4 "Unknown / M" remaining are user-authored import switch_* dimension tables whose M doesn't match any built-in pattern and isn't expression-referenced (correctly out-of-scope)
• 19 EXTERNALMEASURE proxies tagged with full externalProxy incl. cluster URL
• Toggle button present in Tables-tab footer
