For the `grammarToJson/lambda` call inside both public methods, use `stream=False`. For `pure/v1/execution/execute`, use `stream=True` and call `.iter_content(chunk_size=chunk_size)` on the response. For `pure/v1/execution/generatePlan`, use `stream=False`. + 5. Both public methods take `project_coordinates: ProjectCoordinates` as a required positional parameter (third for execute, second for schema).

The override was intended to route LegendQL execution through Pure, but `to_pure()` on service frames hardcodes `pylegend::test::` as the package prefix — it only works for PyLegend's own test model. Real user services silently fell back to SQL anyway.

The cascade (Pure → depot → SQL) silently hides Pure failures. Since the only real PyLegend consumer uses `to_pure()` for Pure generation (not SQL execution), and since SQL execution will be deleted in Phase 2, the fallback has no legitimate use. If Pure fails and no depot is configured, raise the error. Delete `_pure_to_sql_fallback`. + +**Gap 2 (Warning, PURE-05):** Remove stale `@pytest.mark.xfail` from `test_e2e_pure_schema_api` and `test_e2e_pure_execute_api`; add `depot_server_host`/`depot_server_port` so they use the depot cascade (same pattern as Plan 04's LegendQL frame tests). + + + +@/Users/deepyaman/github/finos/pylegend/.claude/get-shit-done/workflows/execute-plan.md +@/Users/deepyaman/github/finos/pylegend/.claude/get-shit-done/templates/summary.md + + + +@.planning/ROADMAP.md +@.planning/STATE.md +@.planning/phases/01-fix-pure-foundation/01-CONTEXT.md +@.planning/phases/01-fix-pure-foundation/01-VERIFICATION.md +@pylegend/core/tds/legendql_api/frames/legendql_api_base_tds_frame.py +@pylegend/core/request/legend_client.py +@tests/extensions/tds/frames/legendql_api/test_legendql_api_table_spec_input_frame.py +@tests/core/request/test_legend_client_e2e.py +@tests/conftest.py + + + +## Artifacts this phase produces + +Modified files only — no new files: + +- `pylegend/core/tds/legendql_api/frames/legendql_api_base_tds_frame.py`: `execute_frame` method and `_get_legendql_input_project_coordinates` method deleted; `from pylegend.core.tds.result_handler import ResultHandler` import deleted +- `pylegend/core/request/legend_client.py`: SQL fallback branches deleted from `get_pure_string_schema` and `execute_pure_string`; `_pure_to_sql_fallback` method deleted +- `tests/core/request/test_legend_client_e2e.py`: `@pytest.mark.xfail` removed from two tests; `depot_server_host`/`depot_server_port` added to their `LegendClient` constructors + + + + + + Task 1: Delete execute_frame override and _get_legendql_input_project_coordinates from LegendQLApiBaseTdsFrame + + pylegend/core/tds/legendql_api/frames/legendql_api_base_tds_frame.py + + + - pylegend/core/tds/legendql_api/frames/legendql_api_base_tds_frame.py (current state — `execute_frame` at lines 63-72, `_get_legendql_input_project_coordinates` at lines 74-90, `ResultHandler` import at line 45) + - tests/extensions/tds/frames/legendql_api/test_legendql_api_table_spec_input_frame.py (test_table_spec_frame_execution_error at lines 38-54 — this must pass after the deletion with ValueError, no code changes needed here) + + + In `pylegend/core/tds/legendql_api/frames/legendql_api_base_tds_frame.py`: + + 1.

This endpoint is NOT currently registered in `PyLegendSqlServer.java` — adding `Execute` to the Dropwizard environment requires a single-line Java change and a Maven rebuild. A schema/column-info endpoint analogue for Pure does not exist as a separate endpoint: instead, `POST /api/pure/v1/execution/generatePlan` (also in `Execute` class) returns an execution plan whose `resultType` carries column info, or the schema can be derived by executing the Pure expression via the `pure/v1/grammar/grammarToJson/lambda` endpoint to parse the Pure string, then calling `generatePlan`. The simplest approach is to parse the Pure lambda string via the grammar endpoint, then pass the resulting protocol JSON to the execute endpoint. + +The PCT (Protocol Conformance Tests) are NOT a separate Python test suite. They are Java tests inside legend-engine that launch `finos/pylegend:SNAPSHOT` Docker container and execute Python scripts that must generate correct Pure output. The PCT exercises PyLegend's Pure expression generation (CSV frames, applied functions). It does NOT exercise `LegendServiceInputFrame.to_pure()` or `LegendFunctionInputFrame.to_pure()` — those frames are not tested by PCT at all. PCT tests only CSV-backed frames using `#TDS{...}#` as root.

Researcher must find how PyLegend participates (the wiring is unclear from the codebase).

The existing `parse_model` response includes a serializer version that can be used. + +### Pattern 2: Get Pure string schema via generatePlan + +**What:** `POST /api/pure/v1/execution/generatePlan` returns a `SingleExecutionPlan`. For a TDS result, `rootExecutionNode.resultType` has a `tdsColumns` field compatible with `tds_columns_from_json()`. + +**When to use:** At frame construction time to populate column schema. + +```python +# Source: VERIFIED via legend-engine Execute.java generatePlan endpoint +# Plan response tdsColumns format matches what tds_columns_from_json() already parses +response = self._execute_service( + method=RequestMethod.POST, + path="pure/v1/execution/generatePlan", + data=execute_input_json, + headers={"Content-Type": "application/json"}, + stream=False +) +plan_json = json.loads(response.text) +result_type = plan_json["rootExecutionNode"]["resultType"] +# result_type has same structure as sql/v1/execution/schema response +return tds_columns_from_json(json.dumps(result_type)) +``` + +**Note:** This is `[ASSUMED]` as the exact schema of `resultType` for TDS plans needs verification against the running engine. An alternative is to use `sql/v1/execution/schema` with the existing SQL query string for schema retrieval only (since schema doesn't depend on the execution path), and only switch the execution call to Pure. This simpler approach avoids the `generatePlan` complexity entirely for Phase 1. + +### Pattern 3: Pure root expression for LegendServiceInputFrame + +**What:** The correct Pure root expression for a Legend service call. + +**When to use:** In `LegendServiceInputFrame.to_pure()`. + +The existing SQL form uses: `service(pattern => '/simplePersonService', coordinates => 'org.finos.legend.pylegend:pylegend-test-models:0.0.1-SNAPSHOT')` + +The Pure equivalent — based on the test model JSON showing service path `pylegend::test::model::simple` and the reverse PCT showing that the execute endpoint accepts `ExecuteInput.function` as a compiled lambda — uses a service call expression. However, the execute endpoint for services can also work by sending the service path directly in the model. The simplest correct approach is: + +```python +# Source: ASSUMED - inferred from Execute.java pattern and existing codebase structure +# The Pure string that, when parsed by grammarToJson/lambda, gives a valid service call +pure_service_root = f"{{|pylegend::test::service::{service_name}.all()}}" +``` + +**CRITICAL UNKNOWN:** The exact Pure package path and form for calling a service by its HTTP pattern versus by its Pure path. This requires testing against the running engine. The CONTEXT.md D-01 locks this as researcher-discovered. + +**Alternative simpler approach (recommended for Phase 1):** +Keep schema retrieval using `sql/v1/execution/schema` (unchanged), switch only `execute_frame()` to call `pure/v1/execution/execute`. This avoids the complexity of `get_pure_string_schema()` for Phase 1 and still satisfies PURE-03 and PURE-05. PURE-04 becomes a follow-on in the same phase or deferred. + +### Pattern 4: Registering Execute in PyLegendSqlServer.java + +**What:** The `Execute` JAX-RS resource must be registered with the Dropwizard environment. + +**When to use:** In the `run()` method of `PyLegendSqlServer.java`. + +```java +// Source: VERIFIED from Execute.java constructor and GrammarToJson registration pattern +// The Execute class needs ModelManager and PlanExecutor (already constructed) +// GrammarToJson is already registered; Execute needs to be added alongside it + +environment.jersey().register( + new Execute(modelManager, planExecutor, routerExtensions, + generatorExtensions.flatCollect(PlanGeneratorExtension::getExtraPlanTransformers))); +``` + +The `Execute` constructor signature: `Execute(ModelManager, PlanExecutor, Function>, Iterable)`. + +All four arguments are already available in `PyLegendSqlServer.run()`. + +### Pattern 5: `execute_pure_string` / `get_pure_string_schema` method signatures + +Mirror `execute_sql_string` / `get_sql_string_schema` with the Pure string as input: + +```python +# Source: ASSUMED (following Claude's Discretion from CONTEXT.md) +def execute_pure_string( + self, + pure: str, + chunk_size: PyLegendOptional[int] = None +) -> ResponseReader: + # 1. Parse lambda via pure/v1/grammar/grammarToJson/lambda + # 2. Construct ExecuteInput JSON with parsed lambda + model pointer from pure context + # 3.

The SQL endpoints embed coordinates in the SQL query string. The Pure endpoint requires coordinates in `model.sdlcInfo`. This means `execute_pure_string` needs project coordinates as a parameter OR the coordinates are embedded in the Pure string and the model is set to a default/empty context for evaluation. + +**Discovery needed:** Whether the service pattern call `/simplePersonService` resolves via the engine's own model lookup without an explicit `model` pointer, or whether the caller must provide `sdlcInfo`. + +### Anti-Patterns to Avoid + +- **Constructing ExecuteInput protocol JSON by hand from scratch:** The protocol version evolves; always use `grammarToJson/lambda` to parse the Pure lambda, then copy the response into `ExecuteInput.function`. Do not attempt to hand-construct `body: [{_type: "func", function: "project", ...}]`. +- **Calling `pure/v1/execution/execute` without registering `Execute` in the test server:** The endpoint will return 404. Registration is required in `PyLegendSqlServer.java`. +- **Assuming `generatePlan` returns the same JSON as `sql/v1/execution/schema`:** The plan's `resultType.tdsColumns` may have a different structure than the SQL schema response; verify before reusing `tds_columns_from_json()`. +- **Changing the `execute_frame()` method on `BaseTdsFrame` instead of overriding in LegendQL frames:** Per D-07, Legacy and Pandas API frames must continue using SQL. Override in `LegendQLApiExecutableInputTdsFrame` or the LegendQL-specific frame classes only. + +--- + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| Pure grammar → protocol JSON | Hand-construct `LambdaFunction` body array | `pure/v1/grammar/grammarToJson/lambda` endpoint | Protocol JSON is version-sensitive; engine parses its own grammar correctly | +| HTTP retry/session | Custom retry wrapper | Existing `LegendClient._execute_service()` | Already handles retry policy, auth headers, and session management | +| TDS column parsing | New parser for plan result | `tds_columns_from_json()` (if resultType format matches) | Already handles enum and primitive column types | +| Maven install | Bundled or scripted Maven | `pixi global install maven` | pixi is already installed and manages system tools | + +**Key insight:** The Legend engine already does all the hard work of Pure parsing, compilation, and execution. PyLegend's role is to (a) generate the right Pure string and (b) call the right HTTP endpoint with correctly-structured JSON. Both of these are straightforward given the existing patterns. + +--- + +## Common Pitfalls + +### Pitfall 1: Execute class not registered in test server +**What goes wrong:** All calls to `pure/v1/execution/execute` return HTTP 404. +**Why it happens:** `PyLegendSqlServer.java` only registers SQL endpoints. The `Execute` class in `legend-engine-core-query-pure-http-api` is in the shaded JAR but not registered. +**How to avoid:** Add `environment.jersey().register(new Execute(...))` to `PyLegendSqlServer.run()` before running any integration tests. +**Warning signs:** HTTP 404 response from the engine when calling `pure/v1/execution/execute`. + +### Pitfall 2: Forgetting to rebuild the JAR after Java changes +**What goes wrong:** Old JAR is used, Java changes have no effect. +**Why it happens:** `conftest.py` starts the JAR from `target/pylegend-sql-server-1.0-shaded.jar`; if not rebuilt, old code runs. +**How to avoid:** Always run `mvn -f tests/resources/legend/server/pylegend-sql-server/pom.xml clean package` after Java changes, then set `JAVA_HOME` before running pytest. +**Warning signs:** `RuntimeError("Unable to start legend server for testing")` or unexpected 404s. + +### Pitfall 3: Pure execute endpoint needs project coordinates separately +**What goes wrong:** `pure/v1/execution/execute` called without `model.sdlcInfo`, engine cannot resolve the service or function. +**Why it happens:** Unlike SQL (which embeds coordinates in the `service(coordinates=>...)` call), Pure execution resolves model elements via the `model` pointer in the request body. +**How to avoid:** Always pass `sdlcInfo` with groupId/artifactId/version when calling `pure/v1/execution/execute` for service or function frames. The `ProjectCoordinates` object already has this data. +**Warning signs:** Legend engine returns compilation error about unknown service or function path. + +### Pitfall 4: Wrong Pure root expression format for service +**What goes wrong:** `to_pure()` returns a string the engine cannot compile. +**Why it happens:** The exact Pure syntax for calling a service by HTTP pattern vs. by Pure path is not the same as the SQL `service(pattern=>...)` syntax. +**How to avoid:** Test the Pure expression against the running engine via `parse_and_compile_model()` before integrating. The CONTEXT.md D-01 flags this as requiring discovery. +**Warning signs:** Legend engine compilation error when `get_pure_string_schema()` is called at frame construction. + +### Pitfall 5: Confusing PCT scope +**What goes wrong:** Developer spends time trying to find/run PCT Python tests, or breaks PCT by accidentally modifying CSV frame `to_pure()`. +**Why it happens:** PCT lives inside the legend-engine Java repo; it runs against the published Docker image, not the local codebase directly. +**How to avoid:** PCT compliance means: (a) do not break `to_pure()` for `CsvInputFrameAbstract` or `TableSpecInputFrameAbstract`, (b) do not break `LegendQLApiAppliedFunction.to_pure()` implementations. TEST-01 is satisfied passively by not regressing these methods. +**Warning signs:** PCT is not part of `pytest ./tests/` and cannot be run locally without Docker and legend-engine. + +### Pitfall 6: `execute_frame()` change affects all API types +**What goes wrong:** Legacy API and Pandas API frames start failing when their execution switches to Pure (which they don't support yet). +**Why it happens:** `execute_frame()` is defined on `BaseTdsFrame` and calls `execute_sql_string()`. If changed there, all subclasses are affected. +**How to avoid:** Per D-07, only override in LegendQL-specific classes. Either override `execute_frame()` in `LegendQLApiBaseTdsFrame` or `LegendQLApiExecutableInputTdsFrame`, or add a hook method. +**Warning signs:** Legacy API and Pandas API integration tests start failing. + +--- + +## Code Examples + +### Registering Execute in PyLegendSqlServer.java + +```java +// Source: VERIFIED from legend-engine Execute.java constructor signature +// Add after SqlExecute registration (line 119 in current PyLegendSqlServer.java) +environment.jersey().register( + new Execute( + modelManager, + planExecutor, + routerExtensions, + generatorExtensions.flatCollect(PlanGeneratorExtension::getExtraPlanTransformers) + ) +); +// Also register GrammarToJson if not already present (it IS already registered: line 125) +``` + +### `get_sql_string_schema` pattern (existing, for reference) + +```python +# Source: VERIFIED from pylegend/core/request/legend_client.py +def get_sql_string_schema(self, sql: str) -> PyLegendSequence[TdsColumn]: + response = super()._execute_service( + method=RequestMethod.POST, + path="sql/v1/execution/schema", + data=json.dumps({"sql": sql}), + headers={"Content-Type": "application/json"}, + stream=False + ) + return tds_columns_from_json(response.text) +``` + +### `execute_sql_string` pattern (existing, for reference) + +```python +# Source: VERIFIED from pylegend/core/request/legend_client.py +def execute_sql_string(self, sql: str, chunk_size=None) -> ResponseReader: + iter_content = super()._execute_service( + method=RequestMethod.POST, + path="sql/v1/execution/execute", + data=json.dumps({"sql": sql}), + headers={"Content-Type": "application/json"}, + stream=True + ).iter_content(chunk_size=chunk_size) + return ResponseReader(iter_content) +``` + +### Parsing a Pure lambda via grammarToJson/lambda + +```python +# Source: VERIFIED from legend-engine GrammarToJson.java @Path("lambda") endpoint +# The endpoint accepts text/plain and returns LambdaFunction protocol JSON +response = super()._execute_service( + method=RequestMethod.POST, + path="pure/v1/grammar/grammarToJson/lambda", + data=pure_lambda_string, # e.g. "|/simplePersonService->execute()" + headers={"Content-Type": "text/plain"}, + stream=False +) +lambda_json = json.loads(response.text) +# lambda_json = {"_type": "lambda", "body": [...], "parameters": []} +``` + +### execute_pure_string method skeleton + +```python +# Source: ASSUMED (following Claude's Discretion pattern from CONTEXT.md) +def execute_pure_string( + self, + pure: str, + project_coordinates: "ProjectCoordinates", + chunk_size: PyLegendOptional[int] = None +) -> ResponseReader: + lambda_json = self._parse_pure_lambda(pure) # grammarToJson/lambda + execute_input = self._build_execute_input(lambda_json, project_coordinates) + iter_content = super()._execute_service( + method=RequestMethod.POST, + path="pure/v1/execution/execute", + data=json.dumps(execute_input), + headers={"Content-Type": "application/json"}, + stream=True + ).iter_content(chunk_size=chunk_size) + return ResponseReader(iter_content) +``` + +### LegendQLApiLegendServiceInputFrame switch to Pure (PURE-05) + +```python +# Source: ASSUMED — mirror of existing __init__ but using Pure path +# Current (SQL): +# LegendQLApiExecutableInputTdsFrame.__init__( +# self, legend_client=legend_client, +# columns=legend_client.get_sql_string_schema(self.to_sql_query()) +# ) + +# New (Pure): +LegendQLApiExecutableInputTdsFrame.__init__( + self, legend_client=legend_client, + columns=legend_client.get_pure_string_schema( + self.to_pure(), + project_coordinates + ) +) +LegendQLApiLegendServiceInputFrame.set_initialized(self, True) +``` + +--- + +## D-06 Resolution: PCT Wiring Mechanism + +**This was the blocking research item.

The frame now inherits `BaseTdsFrame.execute_frame`, which routes execution through `execute_sql_string`. The deletion is correct and complete; no residual references remain. + +2. **`legend_client.py`** — the SQL fallback branches (`_pure_to_sql_fallback` calls) were removed from both `get_pure_string_schema` and `execute_pure_string`. The deletion is correct. However, the surviving depot-cascade `except RuntimeError` scope remains too wide: it wraps both the HTTP call and the plan-response parsing, so a malformed-but-200 plan response silently triggers a depot retry rather than propagating a diagnostic error. + +3. **`test_legend_client_e2e.py`** — stale `@pytest.mark.xfail` removed from both Pure tests; `LegendClient` constructors now include `depot_server_host`/`depot_server_port`. The changes are functionally correct. A structural inconsistency in the `@pytest.mark.skipif` guards is noted below. + +--- + +## Critical Issues + +### CR-01: Overly Broad `except RuntimeError` Silently Swallows Plan-Parse Failures as "Pure Failed" + +**File:** `pylegend/core/request/legend_client.py:114-150` (and analogously `167-188`) + +**Issue:** In `get_pure_string_schema`, the `try` block (line 114) wraps the HTTP call to `pure/v1/execution/generatePlan` AND the subsequent parsing at lines 123-129. Both the inner `KeyError`/`TypeError` handler (line 125-128) and `_tds_columns_from_plan_result_type` (line 129) raise `RuntimeError` when the plan response is well-formed HTTP but contains unexpected JSON. Those `RuntimeError` instances are caught by the outer `except RuntimeError` at line 130. When a depot server is configured, the code silently retries the depot path instead of surfacing the parse error. A successful primary-path HTTP response with a missing `rootExecutionNode` key is therefore misclassified as "Pure execution failed", and the depot path is attempted — with the original diagnostic discarded. + +The same structural problem exists in `execute_pure_string` (lines 167-188), though it is less severe there because `_tds_columns_from_plan_result_type` is not called in that path. + +**Fix:** Narrow the try block in both methods so only the HTTP call is guarded; move response parsing outside the except scope: + +```python +def get_pure_string_schema(self, pure, project_coordinates): + lambda_response = super()._execute_service(...) + lambda_json = json.loads(lambda_response.text) + execute_input = self._build_execute_input(lambda_json, project_coordinates) + try: + plan_response = super()._execute_service( + method=RequestMethod.POST, + path="pure/v1/execution/generatePlan", + data=json.dumps(execute_input), + headers={"Content-Type": "application/json"}, + stream=False + ) + except RuntimeError as pure_err: + LOGGER.debug("Pure generatePlan failed (%s); attempting depot-based schema", pure_err) + if self.__depot_server_host is not None and self.__depot_server_port is not None: + # ... depot fallback ... + raise + # Parse errors propagate directly — NOT masked as "Pure failed" + plan_json = json.loads(plan_response.text) + try: + result_type = plan_json["rootExecutionNode"]["resultType"] + except (KeyError, TypeError) as e: + raise RuntimeError( + "Unexpected resultType JSON shape from generatePlan: " + + repr(str(plan_json))[:200], e + ) + return self._tds_columns_from_plan_result_type(result_type) +``` + +--- + +## Warnings + +### WR-01: `_get_model_context_data` Uses Raw `requests.get`, Bypassing Auth Scheme and Retry + +**File:** `pylegend/core/request/legend_client.py:201-215` + +**Issue:** The depot model fetch calls `req_lib.get(url)` directly (a bare `import requests as req_lib` inside the method) instead of going through `ServiceClient._execute_service`. This bypasses: (a) the `AuthScheme` configured at `LegendClient` construction time — requests to an authenticated depot server will silently fail with 401/403; (b) the retry adapter configured on the session; (c) the `secure_http` flag — the URL is always built with `http://` (line 203) regardless of how the depot server is actually served. The inline `import requests as req_lib` is also non-idiomatic; `requests` is already imported at module level implicitly through `ServiceClient`. + +**Fix:** Route the depot fetch through `ServiceClient` infrastructure or build the depot URL with an `https://` option controlled by a constructor parameter (e.g., `depot_server_secure_http: bool = False`). At minimum, apply the configured auth scheme headers: + +```python +# Or add depot_server_secure_http param and use self._get_session() / _execute_service +scheme = "https" if self.__depot_server_secure_http else "http" +url = f"{scheme}://{self.__depot_server_host}:{self.__depot_server_port}/..." +``` + +### WR-02: Uncaught `KeyError` in `_build_depot_execute_input` on Service Execution Dict Access + +**File:** `pylegend/core/request/legend_client.py:248-255` + +**Issue:** Lines 250-254 access `execution["func"]`, `execution["mapping"]`, and `execution["runtime"]` without guarding against missing keys. If the depot model contains a service with a non-relational or unexpected execution format, bare `KeyError` propagates out of `_build_depot_execute_input`. This is inconsistent with the project's error-handling convention (wrap in `RuntimeError` with a descriptive message) and surfaces a confusing traceback with no context about which service or field was problematic. + +**Fix:** +```python +try: + return { + "function": execution["func"], + "model": model_pointer, + "context": {"_type": "BaseExecutionContext"}, + "mapping": execution["mapping"], + "runtime": execution["runtime"], + } +except KeyError as e: + raise RuntimeError( + f"Service '{service_full_path}' execution element missing expected key {e}. " + f"Execution dict: {repr(str(execution))[:200]}" + ) from e +``` + +### WR-03: `@pytest.mark.skipif(JAVA_HOME is None)` on Pure Tests Is Inconsistent with Fixture Behaviour + +**File:** `tests/core/request/test_legend_client_e2e.py:118,132` + +**Issue:** The `legend_test_server` session fixture (in `tests/conftest.py:47`) raises `RuntimeError("JAVA_HOME environment variable is not set")` unconditionally when `JAVA_HOME` is absent. This means all six tests in `TestLegendClientE2E` fail at fixture setup regardless — including the four tests without a `skipif` guard. The `@pytest.mark.skipif(os.environ.get("JAVA_HOME") is None, ...)` on `test_e2e_pure_schema_api` and `test_e2e_pure_execute_api` provides no real protection: when `JAVA_HOME` is absent, those two are skipped but the other four still error at the fixture layer. The decoration creates a false impression that these tests are independently optional. + +**Fix:** Either (a) remove the `skipif` from the two Pure tests (they are not more optional than the SQL tests), or (b) add a fixture-level skip guard in `conftest.py` so the entire `legend_test_server` fixture is skipped when `JAVA_HOME` is absent, avoiding errors in the four unguarded tests. Option (b) is the correct fix if the intent is to allow running the test suite without Java installed: + +```python +# conftest.py +@pytest.fixture(scope="session") +def legend_test_server(): + java_home = os.environ.get("JAVA_HOME") + if java_home is None: + pytest.skip("JAVA_HOME unset; skipping legend_test_server") + ... +``` + +--- + +## Info + +### IN-01: Missing Space in Two Error Message String Literals in `range()` + +**File:** `pylegend/core/tds/legendql_api/frames/legendql_api_base_tds_frame.py:364-368,383-385` + +**Issue:** Implicit string concatenation at lines 364–368 produces `"...duration_start, duration_end).(with duration_start_unit..."` — no space before the opening parenthesis.

The scope is purely subtractive — no new functionality is added. + +The most important finding is that the SQL metamodel (`core/sql/`) is NOT confined to `core/sql/`, `core/database/`, and `extensions/database/vendors/`. It permeates the shared language layer: every `PyLegendPrimitive` subclass implements `to_sql_expression()`, and all operation expression classes import from `core.sql.metamodel`. The success criterion says `core/sql/` must not exist, but deleting it without touching the shared layer would break all imports. The plan must account for this cross-cutting cleanup. + +A second cross-cutting dependency: `grammar_method` — a decorator used on dunder methods (`__eq__`, `__add__`, etc.) in ALL shared primitive files (`primitive.py`, `integer.py`, `float.py`, `boolean.py`, `number.py`, `string.py`, `date.py`, `datetime.py`, `strictdate.py`, `decimal.py`) — is defined in `pylegend/core/tds/pandas_api/frames/helpers/series_helper.py`, which is being deleted. The decorator is a simple identity tag (`setattr(func, "_is_grammar_method", True)`) used purely for Pandas API introspection. It must be either removed or re-homed in `pylegend/utils/` before deleting `pandas_api/`. + +The phase also has a critical distinction about `testcontainers`: it is currently a **runtime** dependency in `pyproject.toml` but only used in `pylegend/samples/local_legend_env.py` (samples). Moving it to dev-only is correct; the samples module itself stays (samples/legendql_api/ is kept, samples/pandas_api/ is deleted). + +The LegendQL API function files (e.g., `legendql_api_filter_function.py`) each contain both a `to_sql()` method (used for SQL path) and a `to_pure()` method (used for Pure path). Only `to_sql()` and its imports are deleted from these files; `to_pure()` is preserved. + +**Primary recommendation:** Proceed in three waves: (1) move `grammar_method` out of `pandas_api/`, then delete entire Legacy/Pandas API trees and their test mirrors; (2) gut SQL from shared abstractions (BaseTdsFrame, AppliedFunction, PyLegendTdsFrame, PyLegendPrimitive, all operation classes, project_cooridnates) and from LegendQL function files; (3) prune pyproject.toml, samples, and the root `__init__.py`. + + +## Phase Requirements + +| ID | Description | Research Support | +|----|-------------|------------------| +| REMV-01 | Legacy API (`LegacyApiTdsClient`, all `legacy_api/` modules) is removed from the codebase | Full tree identified — see Architecture Patterns section | +| REMV-02 | Pandas API (`PandasApiTdsClient`, all `pandas_api/` modules) is removed from the codebase | Full tree identified; `grammar_method` dependency must be handled first | +| REMV-03 | SQL metamodel layer (`core/sql/`, `core/database/`, `extensions/database/vendors/`) is removed from the codebase | Identified; requires cross-cutting cleanup of shared language layer too | +| REMV-04 | SQL-related dev dependencies (`sqlalchemy`, `pg8000`, `pymysql`, `cryptography`, `mockito`) are removed from `pyproject.toml` | Confirmed these are dev-group only; straightforward deletion from pyproject.toml | +| REMV-05 | `testcontainers` is moved from runtime dependency to dev-only dependency | Confirmed — used only in `pylegend/samples/local_legend_env.py` | + + +## Project Constraints (from CLAUDE.md) + +- Apache 2.0 header required on every Python file — when editing files, preserve the existing header +- Max line length 127 chars (flake8) +- `mypy` strict mode — all parameters and return types must be annotated +- Every module must define `__all__: PyLegendSequence[str]` +- Public APIs centralized in `__init__.py` files — root `__init__.py` must be updated +- `flake8` linting enforced — no unused imports allowed after deletions +- No direct SQL path invocation after phase is complete +- Python 3.9–3.14 compatibility maintained + +## Architectural Responsibility Map + +| Capability | Primary Tier | Secondary Tier | Rationale | +|------------|-------------|----------------|-----------| +| Legacy API deletion | Package layer (`pylegend/legacy_api_tds_client.py`, `core/tds/legacy_api/`, `core/language/legacy_api/`, `extensions/tds/legacy_api/`) | Tests (`tests/core/tds/legacy_api/`, `tests/extensions/tds/frames/legacy_api/`) | Complete top-to-bottom removal of one query-building layer | +| Pandas API deletion | Package layer (`core/tds/pandas_api/`, `core/language/pandas_api/`, `extensions/tds/pandas_api/`, `samples/pandas_api/`) | Tests (all pandas_api test trees) | Complete top-to-bottom removal of another query-building layer | +| SQL metamodel deletion | Package layer (`core/sql/`, `core/database/`, `extensions/database/vendors/`) | Shared language layer (all primitives and operations that implement `to_sql_expression`) | Cross-cutting — SQL types woven into shared primitives | +| execute_frame / SQL method removal | Abstract base classes (`BaseTdsFrame`, `PyLegendTdsFrame`) | LegendQL function files (remove `to_sql()` method from each) | Interface-level surgery on retained code | +| pyproject.toml cleanup | Build configuration | None | Dependency graph trimming | +| Root `__init__.py` cleanup | Public API surface | `samples/__init__.py`, `core/language/__init__.py` | Remove LegacyApiTdsClient export; remove `agg`/`olap_*` legacy exports | + +## Standard Stack + +This phase performs deletions only — no new libraries are introduced.

Actually, `core/language/shared/primitives/primitive.py` has `to_sql_expression()` as an abstract method, and every primitive subclass implements it using SQL metamodel types. Deleting `core/sql/` without removing these methods causes `ModuleNotFoundError: No module named 'pylegend.core.sql'`. +**Why it happens:** The SQL metamodel was used both as a query builder AND as a type system for expression trees in the shared language layer. +**How to avoid:** Treat `to_sql_expression()` removal in the shared language layer as a separate task in the same phase, not as a consequence of deleting `core/sql/`. +**Warning signs:** Any file in `core/language/shared/` that imports `from pylegend.core.sql`. + +### Pitfall 2: `core/project_cooridnates.py` imports SQL metamodel +**What goes wrong:** `project_cooridnates.py` (retained module, used by LegendQL API) imports `NamedArgumentExpression` and `StringLiteral` from `core.sql.metamodel` for its `sql_params()` method. Deleting `core/sql/` without cleaning `project_cooridnates.py` causes `ImportError` on any LegendQL operation. +**Why it happens:** `sql_params()` was used when building SQL `FunctionCall` nodes for the `service()` table function — a path that no longer exists. +**How to avoid:** Remove `sql_params()` from `ProjectCoordinates` and all subclasses, and remove the SQL import. + +### Pitfall 3: `agg`, `olap_agg`, `olap_rank` are exported from root but ONLY used in Legacy API +**What goes wrong:** `pylegend/__init__.py` currently exports `agg`, `olap_agg`, `olap_rank` which come from `core/language/legacy_api/`. A planner might assume these are used by LegendQL and try to move them. +**What we found:** LegendQL API function tests (`test_legendql_api_aggregate_function.py`, `test_legendql_api_groupby_function.py`) do NOT import `agg` or OLAP helpers — they use inline lambdas. The LegendQL API frames themselves do not import from `legacy_api`. [VERIFIED: grep of `core/tds/legendql_api/` for `legacy_api` — no results] +**How to handle:** Simply remove `agg`, `LegacyApiTdsRow`, `LegacyApiAggregateSpecification`, `LegacyApiOLAPGroupByOperation`, `LegacyApiOLAPAggregation`, `LegacyApiOLAPRank`, `olap_agg`, `olap_rank` from `core/language/__init__.py` and `pylegend/__init__.py`. No re-homing needed. + +### Pitfall 4: `grammar_method` decorator in shared primitives imports from deleted module +**What goes wrong:** `pylegend/core/language/shared/primitives/primitive.py` (and 9 other shared primitive files) imports `grammar_method` from `pylegend.core.tds.pandas_api.frames.helpers.series_helper` — which is being deleted. If `pandas_api/` is deleted before this import is updated, ALL shared primitive imports fail, breaking the entire language layer. +**Why it happens:** The `@grammar_method` decorator was added to dunder methods (`__eq__`, `__ne__`, `__add__`, etc.) in ALL shared primitives to support Pandas API introspection. +**What `grammar_method` does:** It is a simple identity function that sets `func._is_grammar_method = True`. In a post-Pandas world it is still needed as long as the attribute is used, but the implementation can live anywhere. +**How to avoid:** Create `pylegend/utils/grammar_method.py` first, update all 10 shared primitive files to import from it, then delete `pandas_api/`. +**Warning signs:** `from pylegend.core.tds.pandas_api` anywhere in a non-pandas file. + +### Pitfall 5: LegendQL test files have mixed SQL/Pure assertions +**What goes wrong:** Tests in `tests/core/tds/legendql_api/` have both `frame.to_sql_query(FrameToSqlConfig())` assertions (which test the SQL path) and `frame.to_pure_query(FrameToPureConfig())` assertions (which test the Pure path). A naive "delete all tests that use SQL" would remove valuable Pure coverage. +**Why it happens:** The LegendQL functions were tested for both paths side by side. +**How to avoid:** Within each retained test file, only delete the `to_sql_query`/`FrameToSqlConfig` assertions; keep the `to_pure_query`/`FrameToPureConfig` assertions. + +### Pitfall 6: Shared language tests call `to_sql_query_object` as class-level setup +**What goes wrong:** `tests/core/language/shared/primitives/test_integer.py` and similar files call `test_frame.to_sql_query_object(frame_to_sql_config)` at class level to build a `base_query` fixture. After SQL is removed, `to_sql_query_object` no longer exists, so pytest collection fails. +**Why it happens:** The fixture setup interleaves SQL and Pure infrastructure. +**How to avoid:** Remove the SQL fixture setup lines (`base_query = test_frame.to_sql_query_object(...)`, `frame_to_sql_config = FrameToSqlConfig()`, `db_extension = SqlToStringDbExtension()`) and all test methods that use them.

The `add_primitive_methods` function in `series_helper.py` checks `getattr(attr, "_is_grammar_method", False)` to discover which methods to proxy onto Series. After `pandas_api/` is deleted, `add_primitive_methods` is also gone. + - What's unclear: Whether any kept code (e.g., LegendQL tests, shared language tests) introspects `_is_grammar_method` at runtime. + - Recommendation: The safest approach is to keep the decorator as a no-op in `pylegend/utils/grammar_method.py` rather than removing all `@grammar_method` usages across 10 files. This minimizes diff size and preserves the attribute for any future Pandas API reintroduction. The planner can choose to fully strip the decorator in a cleanup wave if preferred. + +2. **`tests/core/language/legendql_api/test_legendql_api_tds_row.py` — partial cleanup or full delete?** + - What we know: The file imports `from pylegend.core.database.sql_to_string import ...` (SQL layer).

If absent, `ibis.legend` silently fails with `AttributeError`. Entry_points are cached at process startup — reinstall required after adding. +- Prevention: Add the entry_point in the first commit. Smoke test: `import ibis; assert hasattr(ibis, 'legend')`. +- Phase: Phase 2 + +**IB-3: Schema resolution not implemented at `Backend.table()` time** +- What goes wrong: If schema discovery is skipped, `frame.columns()` returns `[]` and join/filter validation passes vacuously — generating Pure for a 0-column frame that the engine rejects. +- Prevention: In `Backend.table()`, call the Legend HTTP API to retrieve schema; construct explicit `ibis.Schema`. Assert `len(frame.columns()) > 0` after construction. +- Phase: Phase 2–3 + +**IB-4: Assuming Ibis operations map 1:1 to Pure TDS functions** +- What goes wrong: `as_of_join`, `window_extend` with duration ranges, `aggregate` without `group_by`, and `cast` have no canonical Ibis node. Without custom nodes, these fall through to "not implemented" at execution time, not query-construction time. +- Prevention: Enumerate all `LegendQLApiBaseTdsFrame` methods before writing any compiler code. Classify each as: (a) maps to existing Ibis node, (b) requires custom node, (c) raises `OperationNotDefinedError`. Implement custom nodes for (b) first. +- Phase: Phase 2 + +**IB-5: Building the Pure compiler by string formatting rather than a DAG visitor** +- What goes wrong: String concatenation breaks parenthesisation and lambda scoping for 3+ levels of nesting. +- Prevention: Implement the compiler as a visitor (similar to `SQLGlotCompiler` pattern). Each node type gets a `visit_` method returning a Pure fragment. +- Warning sign: `filter().group_by()` works but `filter().join(other, ...).group_by()` fails. +- Phase: Phase 2 + +**IB-6: Lambda variable naming collisions in nested Pure expressions** +- What goes wrong: Pure TDS functions use lambda parameters (`$x` for filter, `$l`/`$r` for join, `$c` for aggregate). Nested operations can shadow variables. +- Prevention: Use conventional names by function type (verify against existing `to_pure()` snapshots). Or use depth-indexed names (`$x0`, `$x1`). +- Warning sign: `filter().filter()` or `join().filter()` generates Pure that the engine rejects. +- Phase: Phase 2 + +## API Migration / Backwards Compat Pitfalls + +**BC-1: Changing the concrete type returned by frame operations** +- What goes wrong: The internal library subclasses `LegendQLApiTdsFrame`. If operations return a different concrete type, `isinstance` checks and `super()` calls in the internal library break silently. +- Prevention: Every operation must return an instance that is still a `LegendQLApiTdsFrame` subclass. Audit the MRO carefully. +- Warning sign: `isinstance(frame.filter(...), LegendQLApiTdsFrame)` returns `False`. +- Phase: Phase 3 (wrapper) + +**BC-2: `columns()` populated with wrong names or types** +- What goes wrong: Ibis uses names like `int64` and `float64`. `TdsColumn` uses Legend names (`"Integer"`, `"Float"`, `"Number"`). Incomplete mapping causes validators to reject valid columns. +- Prevention: Build an explicit bidirectional type-mapping table. Test every type in the PyLegend test suite. Never rely on `str(ibis_dtype)`. +- Phase: Phase 2–3 + +**BC-3: Hard-removing `to_sql_query()` without deprecation** +- What goes wrong: `to_sql_query()` is abstract on `PyLegendTdsFrame`. Internal library may call it. Hard removal causes `RuntimeError`/`NotImplementedError`. +- Prevention: Add `DeprecationWarning` implementation before hard removal. Communicate in 2.0 release notes. +- Phase: Phase 3–4 + +**BC-4: Eager import of the Postgres SQL extension at module load** +- What goes wrong: `tds_frame.py` eagerly imports the Postgres extension module. Removing the SQL extension without removing this import causes `ImportError` at `import pylegend`. +- Prevention: Remove the eager import in the same commit that removes the SQL extension. Run `grep -r "FrameToSqlConfig\|to_sql_query" pylegend/` before committing. +- Warning sign: `import pylegend` raises `ModuleNotFoundError` after partial SQL removal. +- Phase: Phase 1 or early Phase 2 — must be coordinated + +**BC-5: Renaming `project_cooridnates.py` (the typo) during the refactor** +- What goes wrong: The misspelled module path `pylegend.core.project_cooridnates` is part of the public import surface. Any rename breaks the internal library's import path. +- Prevention: Do not rename this module in 2.0. It is frozen. +- Phase: All phases — treat as frozen + +**BC-6: Removing the JAR-based test server before the Pure execution path is wired** +- What goes wrong: `legend_test_server` fixture starts the Java JAR — the only integration test execution path. Removing it before the Ibis backend can execute queries makes the PCT matrix entirely red. +- Prevention: Keep the JAR fixture alive until there is a replacement fixture. +- Phase: Phase 1 — must be planned before API removal + +## Pure Generation Pitfalls + +**PG-1: Input frames raise `RuntimeError` on `to_pure()` — they are the query roots** +- What goes wrong: `LegendServiceInputFrameAbstract.to_pure()` and `LegendFunctionInputFrameAbstract.to_pure()` both raise `RuntimeError`. In 2.0, Pure generation is execution. +- Prevention: Fix both before any compiler work. Verify correct Pure root expression syntax against Legend documentation. Add unit tests for root frame Pure output independently. +- Phase: Phase 1 — must be done first + +**PG-2: `TableSpecInputFrame` Pure output is non-executable against a Legend engine** +- What goes wrong: Returns `f"#Table({'.'.join(self.table.parts)})#"` — a SQL relational store reference; not valid Pure without a configured relational store. +- Prevention: Document as test-only scaffold. Add guard so `execute_frame()` cannot be called on it. +- Phase: Phase 4 (test cleanup) + +**PG-3: `as_of_join` Pure output has never been validated against a real engine** +- What goes wrong: `to_sql()` raises `RuntimeError`; `to_pure()` exists but has no integration test coverage. May be syntactically correct but semantically wrong. +- Prevention: Require at least one integration test for `as_of_join` before 2.0 ships. Mark as `xfail` if engine is unavailable. +- Phase: Phase 2 (compiler) and Phase 3 (integration) + +**PG-4: Type mapping between Legend types and Ibis types loses precision** +- What goes wrong: Legend's `Number` (abstract supertype) has no direct Ibis equivalent. `StrictDate` vs `date` (timezone handling). `Decimal` requires precision/scale in Ibis but not in Legend. +- Prevention: Build and test the type-mapping table in isolation as a standalone module before integrating. Verify the complete round-trip for all Legend primitive types. +- Phase: Phase 2 + +**PG-5: Column names with spaces not quoted in Pure lambda expressions** +- What goes wrong: Column names like `"Ship Name"` require Pure-compatible quoting (`$x.'Ship Name'`). The Ibis compiler must route through `escape_column_name()` — Ibis normalises column names to Python identifiers internally. +- Prevention: In the compiler's column-reference generation, always use `TdsColumn.get_name()` passed through `escape_column_name()`.
