All methods stubbed with NotImplementedError tagged with the method name so downstream code can compile against the new backend while AC-M3-2 (pool) and AC-M3-3/4 (bulkLoad, query, traverse, parity) fill in the real bodies. Adds @ladybugdb/core@^0.16.1 as a direct dependency per spec 004 architectural decision #3 (user-approved 2026-05-05). Source-level naming stays clean — GraphDbStore / graphdb-adapter.ts — per decision #2. The scoped package identifier is the only place the library brand appears in tracked source; the banned-strings guardrail exempts the @ladybugdb/ scope via a targeted allowlist so every other mention still fails. openStore(opts) factory reads CODEHUB_STORE: unset or "duck" → DuckDbStore; "lbug" → GraphDbStore. Unknown values hard-error. DuckDbStore remains the default (spec 004 §S-M3-1, §W-M3-3).

Every relation kind in `ALL_RELATION_TYPES` (24 live in v1.1 — spec 004 quoted 23 but the source drifted past, so the translator uses the live list) gets its own polymorphic rel table with multiple `FROM/TO` pairs. A single `CodeRelation` rel table with a discriminator column would defeat columnar predicate push-down, so we fan out per spec 004 decision #1. Node-level layout keeps the DuckDB collapse — one `CodeNode` node table with a `kind` discriminator — so later graphHash round-trip tests read the same column set from either store. Embeddings, store meta, cochanges, and symbol summaries get their own node tables; the `EMBEDS` rel links embedding rows back to their source node without a property lookup. Tests assert the DDL shape (5 node tables, 24 + 1 rel tables, every kind from `getAllRelationTypes()` present, default embed dim 768, invalid dims rejected). A banned-literal sweep over the generated DDL catches regressions where the translator could leak a prior-art name; the test's banned-token list is built from character codes at runtime so this test file itself stays compliant with `scripts/check-banned-strings.sh`. --- packages/storage/src/graphdb-schema.test.ts | 122 ++++++++++ packages/storage/src/graphdb-schema.ts | 244 ++++++++++++++++++++ packages/storage/src/index.ts | 5 + 3 files changed, 371 insertions(+) create mode 100644 packages/storage/src/graphdb-schema.test.ts create mode 100644 packages/storage/src/graphdb-schema.ts diff --git a/packages/storage/src/graphdb-schema.test.ts b/packages/storage/src/graphdb-schema.test.ts new file mode 100644 index 00000000..18cc944a --- /dev/null +++ b/packages/storage/src/graphdb-schema.test.ts @@ -0,0 +1,122 @@ +import assert from "node:assert/strict"; +import { test } from "node:test"; +import { generateSchemaDdl, getAllRelationTypes } from "./graphdb-schema.js"; + +// NOTE: the spec quoted "23 edge kinds" (spec 004 L11) but the live source +// of truth `duckdb-adapter.ts:ALL_RELATION_TYPES` carries 24.

The dispatcher runs `installScipTool` for binary tools and emits the `dotnet tool install --global scip-dotnet` hint for the .NET path. Files: - packages/cli/src/commands/setup.ts: new `runSetupScip`, `parseScipFlag`, and `SetupScipOptions`/`SetupScipResult` types. Errors never throw past the function boundary — they are collected into `failed[]` so `--scip=all` finishes the installable tools when `scip-dotnet` can't find the .NET SDK. - packages/cli/src/index.ts: new `--scip ` option on `codehub setup`. Updated the command description to mention SCIP adapter installs. The handler parses the flag via `parseScipFlag`, then calls `runSetupScip({ tool, force })`. - packages/cli/src/commands/setup.test.ts: four new tests — parseScipFlag happy path, parseScipFlag rejection path, runSetupScip for the dotnet-tool branch (tolerates both `dotnet` present + absent), and the single-tool install via injected fetch + pin override.

COBOL has no tree-sitter grammar and will ship via a regex hot path in `packages/ingestion/src/parse/cobol-regex.ts`; this commit only adds the union member plus the minimum registrations that the compile-time `satisfies Record` constraints require. Adds: - cobol union member with explanatory comment - cobolProvider stub (empty extractions) so providers/registry.ts compiles; the regex hot path owns actual extraction - empty-string placeholder in GRAMMAR_PACKAGE_BY_LANGUAGE (marks a regex-provider language to getGrammarSha) - empty-string COBOL_QUERY placeholder in unified-queries.ts - "cobol" name in the ProjectProfile language-name registry - cobol entries in registry.test.ts (extensions, MRO, heritage) T-M4-5 Commit 2 replaces these stubs with a proper LanguageProvider discriminated union (the regex-provider escape hatch).

Tree-sitter candidates take the existing path (worker pool + parse cache + provider extract hooks). Cobol candidates bypass the pool entirely: the phase reads the file, calls parseCobolFile, emits one CodeElement node per CobolElement with a DEFINES edge from the file (reason: "cobol-regex:"), and emits IMPORTS edges for COPY refs to external /cobol-copybook: stubs. The shape mirrors how tree-sitter IMPORTS resolve unresolved externals, so impact / wiki / contract-map consumers treat them uniformly. Per the task anti-goals: no CALLS edges emitted between paragraphs (regex cannot disambiguate without a full ASG). PERFORM targets surface as CodeElement nodes only. - parse.test.ts: 3 new integration tests on a temp-dir fixture with HELLO.cbl + GREETING.cpy — asserts CodeElement node emission, DEFINES edges by reason tag, and external IMPORTS edges. Test count: 594 → 598. `mise run check` clean; banned-strings / biome / tsc / test all pass.

No tree-sitter, no AST library — line/regex scans are enough for the top-level shapes stage 3 needs to recognize. Inspectors: - next.config.{js,mjs,ts,cjs} — App Router vs Pages Router (via app/ and pages/ presence or experimental.appDir: true) plus hybrid - astro.config.{mjs,ts,js} — integrations: [...] function-call names - vite.config.{js,mjs,ts,cjs} — plugins: [...] function-call names - META-INF/spring.factories — EnableAutoConfiguration and other keys Each finding carries {framework, source, detail, variant?} so the commit-6 shape change can feed these straight into Evidence[]. Tests: 10 new (4 next.config + 2 astro + 1 vite + 2 spring-boot + 1 absent-files).

Implementation notes: - ImportStageGraph structural interface decouples the stage from the full KnowledgeGraph class so callers (and tests) can supply a minimal subset: edges() + getNode(). - Parses the scip/parse pipeline's "external import: :" stub content format. - Prefix-matches source against FRAMEWORK_ROOT_MODULES with longest-key wins (future-proof for overlapping prefixes). - Tiered: edge confidence >= 1 (scip-resolved) -> deterministic, otherwise heuristic. - Deduped by (framework, source); deterministic sort for byte-identity. 26 frameworks in the root-module registry today covering JS, Python, Ruby, Java/Spring, PHP, .NET. Tests: 11 new (4 positive + 1 tiering + 2 dedup/ordering + 4 negative). Frameworks tests go from 73 to 84. Note: the dispatcher wiring (folding ImportFinding into FrameworkDetection) lands in commit 6 alongside the signals->evidence shape change, since both touch the same code paths. --- packages/frameworks/src/index.ts | 8 + .../frameworks/src/stages/imports.test.ts | 167 +++++++++++++++++ packages/frameworks/src/stages/imports.ts | 170 ++++++++++++++++++ 3 files changed, 345 insertions(+) create mode 100644 packages/frameworks/src/stages/imports.test.ts create mode 100644 packages/frameworks/src/stages/imports.ts diff --git a/packages/frameworks/src/index.ts b/packages/frameworks/src/index.ts index 1925861a..8f4b013d 100644 --- a/packages/frameworks/src/index.ts +++ b/packages/frameworks/src/index.ts @@ -36,6 +36,14 @@ export { type ConfigAstFinding, inspectConfigAst, } from "./stages/config-ast.js";

The wrapper uses reflection against `io.proleap.cobol.asg.*` so the SAME `.java` source compiles against any v4.x point release of the library — we do not need to ship a version-specific JAR against which to build. Traversal (shallow first pass): - `CobolParserRunnerImpl.analyzeFile(file, FIXED)` → Program ASG root. - Walks CompilationUnits → ProgramUnit → IDENTIFICATION / PROCEDURE divisions. Emits one NDJSON record per program-id, paragraph, perform call-site, and copybook inclusion. - Per-file try/catch emits a `diagnostic` record so one bad file can't kill the batch — commit 4 turns those into silent regex-fallback triggers. Compile verification: `javac packages/cobol-proleap/java/cobol_to_scip.java` succeeds with JDK 17+ and no classpath because reflection removes the ProLeap compile-time dependency. The library JAR is only required at runtime, consistent with how `codehub setup --cobol-proleap` resolves it. Test: 4 new `java-source` tests lock in the class name, main signature, runner FQN, and CobolSourceFormatEnum.FIXED reference so a rename is caught before the wrapper ships. --- packages/cobol-proleap/README.md | 38 +++- .../cobol-proleap/java/cobol_to_scip.java | 204 ++++++++++++++---- .../cobol-proleap/src/java-source.test.ts | 57 +++++ 3 files changed, 252 insertions(+), 47 deletions(-) create mode 100644 packages/cobol-proleap/src/java-source.test.ts diff --git a/packages/cobol-proleap/README.md b/packages/cobol-proleap/README.md index a26eb63b..3b22d449 100644 --- a/packages/cobol-proleap/README.md +++ b/packages/cobol-proleap/README.md @@ -23,15 +23,35 @@ single bad file never aborts the run (spec AC-M4-6 success criterion #3). ## Install -The library is NOT on Maven Central. `codehub setup --cobol-proleap` performs -the one-time bootstrap: - -1. `git clone https://github.com/uwol/cobol-parser --branch master - ` — grabs the source. -2. `mvn install -DskipTests` — builds the JAR from source. -3. `javac -cp cobol_to_scip.java` — compiles our wrapper against the - resulting JAR. -4.

Also exports parseCobolFile + CobolElement types from @opencodehub/ingestion's parse barrel so the bridge doesn't reach into deep paths. 5 new tests cover the empty-batch short-circuit, the upfront JarMissingError precondition on the public entry, and the regex-fallback projection path (happy-path + missing-file).
