# Task 2 Report ## Outcome Task 2 is implemented on `main`. The console now has a pure selected-step projection for keyed and compiled drafts, parser-first canonical input/output binding handling, unsupported-row preservation, ordered row serializers, schema-informed suggestions and source previews, structural diagnostic mapping, and presence-aware setup metadata projection. ## Changed Files - `web/apps/console/src/workspace/domain/draft-workspace-models.ts`: Added `StatePath`, `OutputBinding`, and focused input/output binding mutation input types. - `web/apps/console/src/workspace/authoring/selected-step-dataflow.ts`: Added canonical projection, structural path guards, row projections, single-row and list serializers, schema helpers, preview selection, and diagnostic ownership mapping. - `web/apps/console/src/workspace/authoring/selected-step-dataflow.test.ts`: Added keyed/compiled equivalence, ordering, null/zero/absent metadata, structural paths, malformed rows, output target rejection, serializer save blocking, suggestions, previews, and positive/negative diagnostic tests. - `web/apps/console/src/workspace/authoring/canonical-capability-form.ts`: Preserved absent setup metadata as omitted properties without synthesizing nulls in the binding projection. - `web/apps/console/src/workspace/authoring/canonical-capability-form.test.ts`: Added absent, explicit-null, and numeric-zero metadata tests. - `.superpowers/sdd/2026-08-09-workflow-console-selected-step-dataflow/task-2-report.md`: This report. ## TDD Evidence ### RED After writing the pure projection and setup tests, the prescribed command failed before collecting tests because `selected-step-dataflow.ts` did not exist: ```text Test Files 1 failed (1) Tests no tests Error: Failed to resolve import "./selected-step-dataflow.js" ``` This was the expected missing-production-module failure from the Task 2 brief, not a test assertion or environment failure. ### GREEN The first implementation run exposed five behavior/type defects. They were fixed test-first: structural state path segments were preserved, structural input roots were included during serialization, missing previews returned `null`, focused diagnostics honored the requested field, and array-item target suggestions were asserted. The final focused run passed: ```text Test Files 2 passed (2) Tests 10 passed (10) ``` ## Verification - `pnpm --dir web --filter @lda/console test -- src/workspace/authoring/selected-step-dataflow.test.ts src/workspace/authoring/canonical-capability-form.test.ts`: passed, `10/10`. - `pnpm --dir web --filter @lda/console test -- src/workspace/authoring/selected-step-dataflow.test.ts src/workspace/authoring/canonical-capability-form.test.ts src/workspace/authoring/ContextInspector.test.tsx src/workspace/authoring/CapabilityNodeForm.test.tsx`: passed, `17/17`. - `pnpm --dir web --filter @lda/console typecheck`: passed. - `git diff --check`: passed; Git reported only normal LF/CRLF conversion warnings for modified files. - No Serena configuration was modified. ## Deviations - No controller, transport, or React dataflow forms were added. Those are later plan tasks; Task 2's exact file list is limited to the domain models, pure projection module/tests, and canonical setup projection/tests. - The compiled fixture uses the repository's actual `nodes[]` capability key, `node`, while keyed drafts use `use`. - The list serializers return `null` while unsupported rows remain, providing the pure save-blocking behavior needed by later forms; removing unsupported rows before serialization is the explicit repair path. ## Concerns - `bindingDiagnosticsForStep` receives only diagnostics, `stepId`, and field, so it conservatively anchors `nodes[N]` ownership to the first matching selected step node diagnostic. If a backend sends a node-indexed diagnostic without a matching `step_id` or without another selected-step node anchor, it remains unmatched rather than risking assignment to the wrong row. The keyed JSON Pointer and focused `bindings[M]` forms do not have this limitation. - Literal input values remain typed as the existing domain `unknown`; the generated RPC/runtime contract remains authoritative for recursive JSON-value validation at transport time. ## Round 1/5 Review Fix ### Changed Files - `web/apps/console/src/workspace/authoring/selected-step-dataflow.ts`: Added strict JSON Pointer segment decoding, non-negative decimal array-index traversal, explicit `compiledNodeIndex` projection context, and recursive finite JSON literal validation. - `web/apps/console/src/workspace/authoring/selected-step-dataflow.test.ts`: Added regression coverage for invalid `~2` escapes, array `items.1` traversal and non-index rejection, compiled diagnostics with only the row diagnostic present, wrong node indexes, and invalid recursive literal values. - `.superpowers/sdd/2026-08-09-workflow-console-selected-step-dataflow/task-2-report.md`: Appended this review round. ### RED Before the production fixes, the focused pure-module run reported `5` failed tests out of `10`: the projection lacked `compiledNodeIndex`, `isJsonValue` was not exported, `items.1` preview returned `null`, invalid pointer escapes were accepted as row locations, and a wrong compiled node index was not kept unmatched. The failures were assertion failures against the intended behavior, not test collection or type errors. ### GREEN After the fixes: ```text Test Files 1 passed (1) Tests 10 passed (10) ``` `SelectedStepDataflow.compiledNodeIndex` is now `null` for keyed drafts and the selected `nodes[]` index for compiled drafts. `bindingDiagnosticsForStep` takes that explicit index and never derives ownership from another diagnostic. ### Verification - `pnpm --dir web --filter @lda/console test -- src/workspace/authoring/selected-step-dataflow.test.ts`: passed, `10/10`. - `pnpm --dir web --filter @lda/console typecheck`: passed. - `git diff --check`: passed; only normal Git LF/CRLF conversion warnings were reported. - No Serena configuration was modified. ### Deferred Cross-Task Acceptance The existing `ContextInspector` branch still uses the older canonical capability-binding projection and can drop malformed input rows. This is not resolved in Task 2. Task 7 must replace that selected-capability branch with `SelectedCapabilityInspector` and test that it consumes `inputBindingRows(...)` and `outputBindingRows(...)`, preserving unsupported rows and the explicit save gate. ### Concerns - The pure diagnostic helper now conservatively leaves compiled node paths unmatched when the caller supplies `null` or a wrong node index. This is intentional: ownership is explicit rather than inferred from unrelated diagnostics. - Literal validation is client-side recursive finite JSON validation; the generated transport contract remains authoritative at the RPC boundary.
