Some compile seams hard-code spark or document only spark/duckdb, so a downstream validator can still reject databricks or silently bypass the requested dialect.\nROOT CAUSE: src/tablespec/e2e/compile.py:129 forwards the caller dialect to generate_dbt_dag_project, but src/tablespec/e2e/compile.py:141 hard-codes generate_ldp_project(..., dialect=\"spark\"). src/tablespec/e2e/compile.py:193 calls generate_ingest_sql without a dialect, and src/tablespec/schemas/ingest_generator.py:214 hard-codes build_ingest_select(..., dialect=\"spark\"). src/tablespec/ldp/project.py:242 documents LDP dialect as Spark with duckdb accepted for parity, but omits databricks even though LDP runs on Databricks.\nPROPOSED FIX: Make compile_umfs accept dialect=\"databricks\" across all relevant compile seams. Preserve dbt target behavior as databricks, and normalize Spark-family SQL emitters internally where SQL is identical.

ProfileToGxMapper currently emits approximate single-column uniqueness expectations from approximate distinct ratios, but that is not primary-key detection and can duplicate future inferred-key expectations. Users expect bootstrap/profile enrichment to surface likely keys while keeping authoritative UMF.primary_key and unique_constraints separate.\n\nROOT CAUSE: src/tablespec/profiling/types.py DataFrameProfile has only num_records and columns. src/tablespec/profiling/native_profiler.py computes per-column statistics but no key candidate model, scoring, exact verification, or minimality checks. src/tablespec/profiling/gx_expectation_builder.py has a separate approximate uniqueness threshold and no concept of verified key candidates.\n\nPROPOSED FIX: Add typed, JSON-serializable KeyCandidate and KeyCandidateEvidence models to the profiling layer. Add optional key-candidate inference to NativeSparkProfiler with defaults that preserve existing behavior unless enabled. Candidate inference must be advisory: it returns key_candidates on DataFrameProfile but does not mutate UMF.

Review found expect_compound_columns_to_be_unique is allowed in the UMF/GX validation type surface but is not present in the native executor dispatch table. If inferred composite key candidates emit a compound uniqueness expectation merely because the type is allowed by schema, the suite may claim enforcement without actually executing it. That is worse than advisory-only output.\n\nROOT CAUSE: Validation support is split between model/schema allowlists and runtime executor dispatch. FEAT-007 owns execution. Candidate key inference must define \"supported\" as executable by the native executor, not just representable in a suite.\n\nPROPOSED FIX: Make compound uniqueness enforcement explicit and testable. Either implement a Connect-safe native evaluator for expect_compound_columns_to_be_unique, or quarantine composite inferred candidates so they persist only as key-candidate evidence and do not emit a suite expectation until the evaluator exists. The final implementation must make this decision visible in code and tests so future agents do not confuse schema allowance with runtime enforcement.\n\nRequired behavior:\n- A helper or registry makes enforceable expectation types distinguishable from schema-allowed expectation types.\n- Inferred composite key candidates emit compound uniqueness suite expectations only when expect_compound_columns_to_be_unique is executable by the native executor path.\n- If compound uniqueness remains unsupported, composite candidates still persist as sidecar evidence but no validation suite expectation is emitted for them, and evidence/reason states unsupported_by_native_executor.\n- Classic Spark and Connect/Sail behavior must agree: no silent dropped result, no success=false empty result caused by GX dropping unsupported expectations, and no false claim of enforced composite uniqueness.\n\nIn-scope files:\n- src/tablespec/validation/native_executor.py\n- src/tablespec/validation/gx_executor.py if fail-closed routing needs an enforceability check\n- src/tablespec/profiling/gx_expectation_builder.py if candidate-derived expectation emission is gated there\n- src/tablespec/models/umf.py only if comments/constants need to distinguish allowed vs executable validation types\n- tests/unit/test_validation_compound_uniqueness.py or equivalent focused tests\n- tests/unit/test_native_profiler_key_candidates.py only for expectation-emission gating assertions\n\nOut-of-scope for this bead:\n- Profiler candidate scoring/model implementation; depends on tablespec-29002b40.\n- Bootstrap sidecar and manifest layout; tracked by FEAT-026 child.\n- Changing dbt or LDP generator semantics for authoritative UMF.primary_key.","id":"tablespec-5e65545a","issue_type":"task","labels":["area:validation","area:profiling","kind:bug"],"owner":"erik","parent":"tablespec-cc4f665b","priority":1,"schema_version":1,"spec-id":"FEAT-007","status":"closed","title":"Close compound uniqueness execution gap for inferred key candidates","updated_at":"2026-06-09T20:47:17.969094451Z"}

 ## Overview
 
 Make the guidebook + profiling application deployable into any Databricks
-environment as a configured step of the tablespec process. Today the
-application is bound to one workspace by environment literals embedded in its
-source; this feature makes the metadata location a declared input and adds an
-explicit provisioning step, satisfying FR-23.1–FR-23.6.
+environment as a configured step of the tablespec process. The metadata location

 ### Subsystem: App Deployment & Configuration
 
-**FR-23** requirement family. *Governs deployment and configuration of the guidebook + profiling Databricks App (`apps/data-profiling/`) so one source tree deploys into any workspace. The metadata substrate is already location-parameterized (`delta_repo.ensure_tables(catalog, schema)`, `VolumeRef`); this family is the desired deployability contract. Feature decomposition is FEAT-034; configuration precedence is ADR-019. Implementation gaps (portable config, provisioning, startup diagnostics, app e2e) are tracked in the alignment bead epic, not by shrinking these requirements.*

 - **FR-23.1** — **Resolved runtime configuration.** The app resolves every environment-specific setting through one configuration object with a fixed precedence: deployment-supplied environment variables → `connections.yaml` → built-in defaults. No catalog, schema, volume, warehouse id, or workspace URL appears as a literal in application code.
 - **FR-23.2** — **Declared governance location.** The metadata home is a declared `(catalog, schema)` pair plus an output volume. Every governance table and every volume path derives from that declaration, so relocating the metadata is a configuration change, not a code change.
