testkit: register Spark's test udf in the golden session engine - #346
The golden session engine never registered the udf function that Spark's SQLQueryTestSuite adds for the udf/ folders. udf(x) is an identity that keeps the argument's type (IntegratedUDFTestUtils), registered through Session::register_udf.
329 goldens now pass, none added to the known failures (ratchet updated; result 10,243 / 15,363).
Not covered: udaf (needs aggregate UDFs in the engine, about 104 statements) and the PostgreSQL helpers booleq/boolne/vol. Test-only change, no product code touched.
…goldens)
udf(x) is an identity that keeps the argument's type, as IntegratedUDFTestUtils'
TestScalaUDF does. udaf needs aggregate UDFs and stays unregistered.

- Line 58: Update IdentityUdf::invoke to normalize view-backed results before
returning: convert Utf8View to Utf8 and BinaryView to Binary, while returning
already matching Utf8 and Binary carriers unchanged.

Walkthrough
The golden testkit adds an identity UDF and registers setup UDFs during session reset. UDF known-failure fixtures are updated or deleted.
Changes: Golden UDF execution
Layer / File(s)
Summary
Define and register the test UDF crates/krishiv-testkit/src/golden/mod.rs, crates/krishiv-testkit/src/golden/session_engine.rs, crates/krishiv-testkit/src/golden/test_udfs.rs
Adds the public test_udfs module and a one-argument identity UDF. Session reset registers setup UDFs and propagates registration errors.
Some golden UDF cases with STRING or BINARY inputs can fail. Normalize those results before merging, or accept the bounded testkit risk.

Full details: Docstring Coverage
Explanation
Docstring coverage is 33.33% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 3 functions across 3 files. (12 skipped: 12 unsupported.)
Resolution
Write docstrings for the functions missing them to satisfy the coverage threshold.

Steward C: policy failed on 'Generated with Claude Code' in the PR body, which is already removed; the commits are clean (check-ai-attribution passes locally). The workflow does not re-run on a body edit, so the next push or a label toggle clears it.
Steward C: test fails on golden_ratchet only because two baseline entries now pass and must come off the list (the ratchet only shrinks): udf/postgreSQL/udf-aggregates_part2#23 and udf/udf-inline-table#16. Remove them from tests/spark-golden/known-failures-cases/ (or run golden-report --engine session --ratchet update). Not pushing to an active session's branch.
