The default open path is .codeiq/graph/codeiq.kuzu/ on disk; Open ensures the parent directory exists and lets Kuzu create the database directory itself.

Strips the longest matching suffix from REPOSITORY labels (Repository, Repo, Dao, DAO — first match wins) and emits a QUERIES edge to the case-insensitively named ENTITY. Skips when an explicit QUERIES edge already exists between the same source and target, so detector output isn't duplicated.

Groups non-MODULE nodes by their Module field and emits a MODULE node (reusing an existing one by ID if present) plus a CONTAINS edge per member.

Walks projectRoot directly (not the node list) because not all build files produce CodeNodes during index, so node paths alone miss modules. Emits SERVICE nodes (one per build-file-bearing directory) plus CONTAINS edges from each service to the nodes whose filePath falls under it, deepest-match wins. Supports 30+ build systems via two maps: exact filename (pom.xml, package.json, go.mod, Cargo.toml, pyproject.toml, build.gradle, etc.) and suffix match (*.csproj, *.fsproj, *.vbproj, *.gemspec, *.cabal, *.nimble). Priority rules mirror the Java side: supplemental tools (Docker, nx, lerna, turbo, rush) don't override real build tools; python files follow pyproject.toml > setup.py > requirements.txt > manage.py; gradle settings.* doesn't override build.gradle. Prunes node_modules, .git, target, build, dist, .gradle, .idea, .vscode, __pycache__, .tox, .eggs, venv, .venv, vendor, .bundle, _build, deps from the walk so vendored deps don't masquerade as separate services. Extracts the canonical name from build file contents when possible (artifactId, npm name, go module last segment, cargo name, pyproject name, gradle rootProject.name, sbt name, composer name, mix app, pubspec name) and falls back to the directory name (or projectDir for the root) when no extractor matches. 10 new tests cover the priority rules, dir/projectDir fallback, .csproj suffix path, skip-list enforcement, child assignment + CONTAINS edges + endpoint/entity counts, the no-build-files synthetic "unknown" service, and a determinism check across two runs of the same tree.

Files are read at most once across all nodes sharing a path; per-file work runs on a goroutine per file with results merged in sorted-file order for deterministic output. Also adds model.CapabilityLevel (EXACT, PARTIAL, LEXICAL_ONLY, UNSUPPORTED) to mirror Java's CapabilityLevel — distinct from the per-edge Confidence ladder.

For METHOD nodes, walks the matching method_declaration subtree and emits one CALLS edge per method_invocation that resolves to a unique METHOD node in the registry (ambiguous label = dropped, same guard as Java's lookupByLabel). For CLASS/ABSTRACT_CLASS/INTERFACE nodes, extracts extends_type and implements_types type-hints from the superclass / interfaces fields. Adds parser.Walk, parser.ChildFieldText, parser.ParseByName helpers so extractors can drive the existing tree-sitter parser via string keys.

Implements FindConsumers / FindProducers / FindCallers / FindDependencies / FindDependents / FindShortestPath / FindCycles / FindDeadCode. The Java side wraps Neo4j's single RELATES_TO edge; on Kuzu we filter by LABEL(r) against the per-EdgeKind rel tables. Kuzu 0.7 feature gaps worked around in this commit: - List comprehension [n IN nodes(p) | n.id] is rejected by the binder ("Variable n not in scope"); use properties(nodes(p), 'id') instead. - Parameters declared at the outer WHERE are not visible inside an EXISTS subquery, so the semantic-edge filter is inlined as a rel alternation pattern rather than `LABEL(r) IN $param`. - Kuzu's Go binding accepts []any only, not []string, for LIST parameters — stringsToAny widens.

charset=UTF-8 Content-Transfer-Encoding: 8bit Wires the tree-sitter TypeScript grammar into the parser package (also covers JavaScript — the grammar is a superset) and adds the TS extractor. For METHOD nodes the extractor walks the matching function_declaration / method_definition / arrow_function and emits one CALLS edge per call_expression whose `function` field resolves to a registry node. For MODULE nodes it stamps a `module_exports` type-hint listing the declarations attached to every export_statement in the file. Grammar import: github.com/smacker/go-tree-sitter/typescript/typescript (sub-package of the already-vendored smacker module — no go.mod change).

charset=UTF-8 Content-Transfer-Encoding: 8bit Port TopologyService.java to Go — service-map / service-detail / blast-radius / find-path / find-bottlenecks / find-circular / find-dead-services. The Java side ingests the full node + edge lists and walks them in heap; the Go side uses targeted Cypher queries against the structural CONTAINS edges ServiceDetector emits, so peak memory stays flat regardless of graph size. Implementation choices: - Pivot through CONTAINS rather than parsing the JSON `service` property at query time (no JSON-extract helper in Kuzu 0.7). - extractJSONString / extractJSONInt are single-pass scanners reading build_tool / endpoint_count / entity_count out of the props blob — cheaper than full JSON parse for the few fields we surface. - FindCircular uses an in-Go DFS over the cross-service adjacency, normalising each cycle to start at its lexicographically smallest service for stable output. Kuzu 0.7 feature gaps worked around in this commit: - Combining multi-label rel alternation (r:CALLS|...) with the kleene star in a single recursive pattern breaks the binder; BlastRadius uses an anonymous recursive pattern instead. - ORDER BY after RETURN DISTINCT must reference the projected alias (e.g. `id`), not `b.id` — DISTINCT scope drops the rel pattern's node aliases (same caveat as graph.FindOutgoingNeighbors).

For METHOD nodes the extractor walks the matching function_declaration / method_declaration and emits one CALLS edge per call_expression whose `function` field resolves to a registry node — qualified callees like `log.Println` are stripped to their bare name before lookup. For CLASS nodes it regex-matches the `var _ Iface = (*Foo)(nil)` interface-assertion idiom and stamps `implements_types` with the interface qualifier. Grammar import: github.com/smacker/go-tree-sitter/golang (sub-package of the already-vendored smacker module — no go.mod change).

Enrich rehydrates the SQLite cache, runs the three linkers (TopicLinker, EntityLinker, ModuleContainmentLinker), layer classifier, lexical enricher, language extractors (Java, TypeScript, Python, Go), and the filesystem-driven service detector, then bulk-loads Kuzu and creates the FTS-equivalent indexes. Adds `resolvePath` / `printOrdered` CLI helpers and an `OrderedMap` MarshalJSON shim so query results serialise with deterministic key order.

From 3d0ecae67d3c89cda4be3ec76918f3050133d7a1 Mon Sep 17 00:00:00 2001 From: Amit Kumar Date: Tue, 12 May 2026 02:13:01 +0000 Subject: [PATCH 065/189] feat(go/cli): query subcommands (consumers, producers, callers, deps, dependents) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the `codeiq query` parent command and the five preset finder subcommands backed by query.Service. Each subcommand resolves the graph directory the same way (--graph-dir override, otherwise default under the project root), opens the Kuzu store read-only, and prints tab-separated `id\tkind\tlabel` rows sorted by id for deterministic output. Extends docs_test.go to recurse into nested subcommands so the §7.1 documentation contract is enforced for `codeiq query ` as well as top-level commands.

Bare `topology` renders the service map (services plus cross-service runtime connections + count aggregates). Each sub-view is a thin Cobra wrapper around query.Topology methods, returning JSON via the OrderedMap.MarshalJSON path so output is deterministic and easily diffed.

Components: - parity/kuzu_dump.go: DumpKuzu(dir) opens the Kuzu store, projects every CodeNode (id/kind/label/fqn/file_path/layer/framework/language plus the prop_lex_comment / prop_lex_config_keys lexical fields) and every edge (id/kind/source/target), Go-side sorts by id, and serializes with empty- slice coercion so the JSON output stays stable across empty stores. - parity/kuzu_dump_test.go: TestDumpKuzuEmptyStore + TestDumpKuzuIsDeterministic. Schema-only, no enrich required — runs without the parity build tag. - parity/parity_test.go: TestFixtureMultiLangParityPhase2 builds the Go binary, runs index + enrich on testdata/fixture-multi-lang, calls DumpKuzu, and either snapshots (TEST_JAVA_KUZU_DUMP unset) or diffs against the Java side. Mismatches write the Go dump to t.TempDir() and print the path for CI artifact upload. diffJSON now renders via pmezard/go-difflib's unified format, with the allowlist applied line-by-line so allowed deltas are absorbed and only unexplained drift fails the build. - go.mod: promote github.com/pmezard/go-difflib v1.0.0 from indirect to direct (transitive in phase 1 via stretchr/testify, now used by the parity harness directly). - testdata/fixture-multi-lang/expected-divergence.json: switch property_ drift to string tags so the divergenceFile schema stays []string for fixture-minimal compatibility. Verification (CGO_ENABLED=1): go test ./parity/... -> 3 passed go test -tags=parity ./parity/... -> 5 passed go vet ./... -> clean go test ./... -count=1 -> 282 passed Kuzu-specific notes captured inline: rel-type accessor is label(r) not type(r) in Kuzu 0.7.1; LIMIT/SKIP can't be parameter-bound; ORDER BY scope drops after DISTINCT — Go-side sort is the safety net.

Wraps the SDK so callers register mcp.Tool {Name, Description, Schema, Handler} and Serve(ctx, transport) delegates to Server.Run. The Handler signature is the simple json.RawMessage shape from the plan; the SDK's ToolHandler unmarshalling happens inside Tool.asSDKTool. SDK API anomaly vs. plan: v1.x has no NewStdioTransport(in, out) and no ServerTool aggregate. Tests use NewInMemoryTransports; CLI will pass &StdioTransport{} (zero value, hard-bound to os.Stdin/os.Stdout). The wrapper hides this — Serve takes any mcp.Transport. 5 tests cover handshake, tools/list, tools/call round-trip, and the registry's duplicate/empty/nil-handler rejection.

read-only Kuzu open + mutation gate + row-cap iter MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit graph.OpenReadOnly(path, timeout) opens an existing Kuzu store with the SDK read-only flag set and applies a per-query wall-clock timeout via Connection.SetTimeout (Kuzu uses milliseconds). Timeout=0 disables the cap; defaults to 30s to match Neo4jConfig.transaction_timeout. graph.MutationKeyword(q) scans for blocked write keywords (CREATE, DELETE, DETACH, SET, REMOVE, MERGE, DROP, FOREACH, LOAD CSV, COPY) and gates CALL on a read-only-procedure allow-list (db.*, show_*, table_*, current_setting, table_info). Block-comment + line-comment strip happens before keyword detection so commented-out writes don't trip the gate. Earliest match wins so "DETACH DELETE" surfaces "DETACH". Go RE2 has no lookahead, so the CALL gate is a two-stage match (find all CALL sites, then allow-list each procedure name) rather than a single negative-lookahead regex. Store.Cypher now rejects mutation queries when readOnly=true. Store.CypherRows iterates up to maxRows then peeks one tuple to set truncated=true — cap enforced in the loop, NOT injected as LIMIT N into the user-supplied query (spec §8 gotcha).

Mirrors Java McpTools.generateFlow but routes JSON/YAML/Mermaid/DOT through the new Go renderers (Java only ships JSON+Mermaid today). Adds Flow / Evidence / QueryPlanner / ArtifactMeta fields to Deps so the remaining intelligence tools can plug in. Updates the SDK tool wrapper to pass plain-string returns through verbatim — generate_flow emits already-rendered text that must not be JSON-double-encoded.

Always runs the structural search (label/fqn substring) — the planner's route is advisory and surfaces via degradation_note. LEXICAL_FIRST / MERGED routes augment with a lexical pass (doc-comment + config-key match). get_evidence_pack: wraps internal/intelligence/evidence.Assembler. Falls back to the legacy `{"error":"...unavailable. Run 'enrich' first."}` envelope when Evidence is not wired — matches the Java contract so existing MCP clients reading `error` keep working. get_artifact_metadata: returns the most recent provenance snapshot from Deps.ArtifactMeta with the same legacy-error envelope when nil. get_capabilities: returns the per-language CapabilityMatrix — either the full matrix or a single language row, matching Java McpTools .getCapabilities key-for-key. Wires every tool family in cli/mcp.go: graph (20) + topology (9) + flow (1) + intelligence (4) = 34 tools total. tools/list now lands all 34 entries; the optionalRegisterHooks slice is reserved for future tool-family extensions.

KubernetesDetector MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Detect 17 standard k8s resource kinds. Emits INFRA_RESOURCE per manifest with kind/namespace/labels props; workload kinds (Deployment/Pod/etc.) get CONFIG_KEY child nodes for each container with image/ports/env_vars. Cross-resource edges: - Service→Deployment via matchLabels selector (DEPENDS_ON) - Ingress→Service via backend.service.name (CONNECTS_TO) Sorted iteration on label / selector maps for determinism.

DEPENDS_ON edges follow `$ref` strings between schemas in the same file. - GitLabCiDetector: pipeline MODULE + stage CONFIG_KEYs + job METHODs. needs → DEPENDS_ON, extends → EXTENDS, include → IMPORTS. Tool detection greps job scripts for docker/helm/kubectl/terraform/etc. - CloudFormationDetector: INFRA_RESOURCE per Resource, CONFIG_DEFINITION per Parameter / Output. DEPENDS_ON edges follow Ref + Fn::GetAtt references recursively in resource bodies. Discriminator: AWSTemplateFormatVersion or any AWS:: resource type. - KubernetesRbacDetector: GUARD nodes for Role / ClusterRole / RoleBinding / ClusterRoleBinding / ServiceAccount; PROTECTS edges from each Role to bound ServiceAccount subjects via roleRef.
