Three milestones of parallel-work traffic +later, four facts forced the M7 architectural shift. + +1. **DuckDB's recursive-CTE traversals do not get faster.** The shape + limit identified in ADR 0011 §Context (one polymorphic `relations` + table, `WHERE type = ?` evaluated after the join, no per-kind + columnar pushdown) holds across every workload we measured in M4 – + M6. The 24-edge-kind cardinality is now 28 with M5/M6 additions + (`HAS_FILE`, `HAS_DEPENDENCY`, `IN_GROUP`, `OWNED_BY` repo-level + edges). DuckDB is the right engine for time-series / cochange + queries — its column-store strengths land squarely in the temporal + domain — but the graph workload is a different shape and benefits + from a graph-native engine. +2. **The `IGraphStore` interface had grown two non-graph + responsibilities.** By the end of M6 it carried `cochanges` and + `symbol-summaries` queries — both temporal, neither graph. Every + community adapter author would have had to implement those two + surfaces against their own engine, even though `Cochange` / + `SymbolSummary` are statistical (git-history) signals that never + enter `graphHash` (the round-trip invariant `interface.ts:122-127` + already documented). Splitting the interface keeps the conformance + bar honest. +3. **108 raw-SQL call sites were scattered across the consumer + packages.** `analysis/` had 27 sites. `mcp/` had 46. `pack/` and + `wiki/` had 15 between them. `cli/` had 20. Every site hard-coded + the DuckDB dialect via `store.query("SELECT ... FROM nodes WHERE + ...")`. The graph-DB backend (ADR 0011) ran the same workload + through a Cypher-emitting dialect adapter, but the consumer-side + shape leaked the DuckDB SQL into every tool and prevented community + adapters (AGE / Memgraph / Neo4j / Neptune) from substituting in. +4. **The `graphHash` parity gate caught every shape regression but + could not catch a contract regression.** ADR 0011 §graphHash + invariant pins the byte-identity of the in-memory `KnowledgeGraph` + across the two backends. That gate cannot tell us, however, whether + `listEdgesByType("CALLS")` returns the same rows as + `listEdges().filter(e => e.type === "CALLS")` — the rebuilder uses + only `listNodes()` + `listEdges()`, so the typed finders had no + second-source equivalence test. Track A adds a public-interface + parity harness AND a community-adapter conformance suite to fill + that gap. + +The clean fix is the M7 architectural shift: split the interface, hoist +the column encoders, migrate every raw-SQL site to typed finders, +publish a parity harness + conformance suite for community adapters, +and flip the default backend to `lbug` when `@ladybugdb/core` is +importable. + +## Decision + +Adopt LadybugDB as the default graph backend, with DuckDB retained as +the legacy graph store + the canonical temporal store.

Lifecycle, schema, bulk write, vector + search, embedding management, 13 typed finders (see §Typed finders + below) plus 2 specialized (xrefs, skeleton). NEVER carries + cochanges, symbol summaries, or temporal-table queries. +- `ITemporalStore` — temporal-only. Cochange + symbol-summary upserts + and reads. Backed by DuckDB regardless of which graph backend is + selected. + +The composed `Store` envelope (`OpenStoreResult`) carries both views. +For the `duck` backend a single `DuckDbStore` instance satisfies both +interfaces structurally and is returned twice (one connection serves +both). For the `lbug` backend a `GraphDbStore` backs `graph` and a +sibling `DuckDbStore` backs `temporal`. + +### Hoisted column encoders + sentinel coercions (AC-A-2) + +`packages/storage/src/column-encode.ts` carries the per-column +serialization rules previously duplicated in +`duckdb-adapter.ts:bulkLoad` and `graphdb-adapter.ts:bulkLoad`. The +hoist resolves the `step: 0` vs `step: null` parity asymmetry (ADR +0011 §graphHash invariant captured the workaround; AC-A-2 makes it a +shared encoder so both adapters cannot drift). + +### Public-interface parity harness + community-adapter conformance suite (AC-A-7, AC-A-11) + +`packages/storage/src/test-utils/parity-harness.ts` exports +`rebuildFromStore(graph: IGraphStore): Promise` and +`assertGraphParity(fixture, {stores: IGraphStore[]})`. The rebuilder +uses ONLY `listNodes()` + `listEdges()` — no SQL, no Cypher, no +adapter-specific surface. A community adapter that satisfies +`IGraphStore` and passes `assertGraphParity` claims conformance. + +`packages/storage/src/test-utils/conformance.ts` exports +`assertIGraphStoreConformance(name, factory)`. The suite asserts the +13 typed finders return well-typed results, `listEdgesByType` is +byte-equivalent to `listEdges().filter`, `traverse` hits the +`(target, depth, path)` invariants, `vectorSearch` is ordered, and +`healthCheck` returns `{ok: true}` after `open() + createSchema()`. +Both DuckDB and LadybugDB adapters opt in by importing the suite in +their respective test files. + +## 13 typed finders + 2 specialized — the service-layer foundation + +`IGraphStore` exposes these read methods (listed by primary caller): + +| Method | Primary callers | +|---|---| +| `listNodes(opts?)` | `parity-harness`, generic listing | +| `listNodesByKind(kind, opts?)` | xrefs, skeleton, list-findings, dependencies, wiki | +| `listNodesByName(name, opts?)` | rename, query, context | +| `listNodesByEntryPoint(opts?)` | route-map | +| `listEdges(opts?)` | parity rebuilder, xrefs, skeleton | +| `listEdgesByType(type, opts?)` | pack/xrefs, pack/skeleton, group-contracts | +| `listEdgesIncidentTo(nodeId, opts?)` | context, impact | +| `listFindings(opts?)` | analysis/verdict, mcp/list-findings, pack/findings, wiki | +| `listEmbeddings(opts?)` | pack/embeddings-sidecar | +| `listEmbeddingHashes()` | dedupe + analyze incremental gate | +| `listDependencies(opts?)` | dependencies tool | +| `listRoutes(opts?)` | route-map | +| `traverse(query)` | impact, context | + +The 2 specialized finders are `loadXrefs(opts)` and +`loadSkeleton(opts)` — both compose multiple typed finders behind a +single call to keep the pack layer's I/O contract narrow. + +## 108-site SQL migration (AC-A-6 a/b/c/d) + +The migration landed in four sub-commits, sequenced sequentially to +keep each commit reviewable: + +| Sub-commit | Package | Sites | +|---|---|---| +| AC-A-6a | `analysis/` | 27 | +| AC-A-6b | `mcp/` | 46 | +| AC-A-6c | `pack/` + `wiki/` | 15 | +| AC-A-6d | `cli/` | 20 | + +Total: **108 raw-SQL call sites** replaced with typed-finder calls. +Every migrated tool runs end-to-end on BOTH DuckDb and LadybugDB +backends (the parity harness is wired into every consumer test). +`packages/analysis/src/test-utils.ts` was rewritten from a +DuckDB-dialect regex fake into a typed `IGraphStore` fake that +implements the finder surface (AC-A-6 sub-task), unblocking the rest +of the consumer-side migration. + +## Dual-artifact detection + +The factory at `packages/storage/src/index.ts:openStore` runs a +post-resolution check via `detectDualArtifacts(graphFile, temporalFile, +backend)`.

The + conformance suite (AC-A-11) is the contract: pass it, claim + conformance. +- The optional `execCypher?(query, params?, opts?)` hook on + `IGraphStore` lets adapters with a Cypher-native query path expose + it for the `sql` MCP tool's `cypher` input mode without leaking + dialect into the consumer-side typed-finder calls. +- `describeArtifacts(backend)` (`packages/storage/src/paths.ts`) + derives `/graph.` for unknown backends, paired with + the canonical `/temporal.duckdb` sibling. The `CodeHub` + registry, `codehub list` indexed-status probe, and the MCP + store-unreadable error envelope all enumerate the candidate paths + via this helper, so a community adapter's on-disk presence is + surfaceable end-to-end without engine-side changes. + +The fallback documented in ADR 0011 §Fallback (Apache AGE on Postgres +18) is now the canonical example of how a community adapter slots in +behind the v1.0 `IGraphStore` seam. An OCH user who wants AGE wires up +an `@opencodehub-community/age` package that implements `IGraphStore`, +exports it, and registers it via the in-tree extension point — no fork +of `@opencodehub/storage` required. + +## Rationale for the default flip + +- **Performance.** Multi-hop graph traversals (`impact`, `context`) + benefit from the rel-table-per-kind shape (ADR 0011 §Schema choice). + M6 measurements showed ~5–8x faster `impact` queries on the same + fixture between the two backends; the gap widens with edge-kind + cardinality. +- **Concurrency.** The LadybugDB pool adapter + (`packages/storage/src/graphdb-pool.ts`, ADR 0011 §Concurrency + model) gives one `Database` per repo + a pool of `Connection` + objects, with the one-query-per-Connection invariant enforced by + the pool. DuckDB's single-connection-per-process posture made the + MCP tools serialize at the connection level — the graph-DB + concurrency model is a strict superset. +- **Future-proofing.** Every new graph-side feature in M5 – M6 was + already written against `IGraphStore` (the M4 – M6 phase plan from + ADR 0011 enforced this). Flipping the default does not require any + consumer-side change beyond the `openStore` factory. +- **The legacy path is preserved.** Setting `CODEHUB_STORE=duck` + retains the old behavior. DuckDB is still the temporal store. No + data is lost; no re-analyze is required for users who stay on the + legacy backend. + +## Risks + +1. **Binding availability gap on first `analyze`.** A user upgrades + OCH and immediately runs `codehub analyze` without + `CODEHUB_STORE=duck`. If `@ladybugdb/core` lacks a prebuilt binary + for their platform, the probe resolves to `false`, the advisory + fires, and the fallback writes a DuckDB artifact. The next session + on a platform WITH the binding will then see a stale DuckDB file + and a fresh attempt to write `graph.lbug` — the dual-artifact + detection catches this exactly: newer-mtime wins. Mitigation: + `codehub doctor` (the storage-side probe) surfaces the binding + status before the user runs analyze. +2. **CI runs producing non-deterministic backends.** A CI matrix + that pins `node@22` + `linux-x64` will get the binding; a matrix + that pins `node@24` (currently waiting on + `node-tree-sitter@0.25.1`, see CLAUDE.md §Parse runtime) might + not. The fix is to set `CODEHUB_STORE=duck` (or `lbug`) explicitly + in CI workflows that need byte-deterministic outputs across + matrix entries. The default-flip is a developer-experience win, + not a CI-determinism contract. +3. **Stderr advisory pollution.** The advisory fires at most once + per process and only under TTY / `OCH_VERBOSE=1`. Non-interactive + CI runs stay quiet. The risk is a misconfigured terminal multiplexer + that reports `isTTY: true` for a non-interactive shell — those + users see one extra line per run, no functional impact. +4. **Community adapters drifting from the conformance contract.** The + conformance suite is opt-in by import in the adapter's test file. + A community adapter that ships without the suite cannot claim + conformance; we recommend (but cannot enforce) that adapter authors + wire the suite into their CI. Mitigation: the v1.0 release notes + call this out, and the published `@opencodehub/storage` + typing surface includes the suite re-export so adapter authors do + not have to discover it. +5. **`describeArtifacts` extending to unknown backends.** The path + helper now generates `/graph.` for any unknown + backend identifier, paired with the canonical + `/temporal.duckdb`. A future in-tree backend that wants a + non-DuckDB temporal store would have to override this. No such + backend is on the v1.0 roadmap; the helper's signature can grow + if needed. + +## Status + +- **Proposed**: 2026-05-09 (Track A AC-A-9 commit). +- **Accepted**: on merge of `feat/v1-finalize-track-a` → `main` (the PR + that ships AC-A-9 alongside AC-A-1 through AC-A-11). +- **Superseded**: not on the v1.0 roadmap.

The M6 federation + surface routes through the new typed finders via this ADR's + AC-A-6 migration. + +## Provenance + +The interface-segregation pattern (graph-only `IGraphStore` plus +temporal-only `ITemporalStore`) follows the SOLID dependency-inversion +shape from `Clean Architecture` (Robert C. Martin, 2017): the +high-level consumer code depends on the abstraction, not on the +concrete adapter, and the abstraction is owned by the consumer side. +The 13-finder service-layer surface is OCH-original — the choice of +which queries to typify came from the 108-site usage census in +`architecture-revised.md` §3, not from a generic graph-DB API. + +The dual-artifact newer-mtime rule has no direct precedent we found; +it is a pragmatic response to the M3 – M7 transition window where +both files coexist on user disks. The same shape recurs in build-tool +caches (Bazel's `bazel-out`, Cargo's `target/`), but those tools use +a checksum-based invalidation; the OCH default-flip cannot rely on +checksums because the two artifacts are written by different engines +and have different on-disk representations. mtime is the only stable +signal. + +## Empirical evidence — graphHash parity audit (AC-A-10) + +The whole-pipeline parity gate is `scripts/m7-parity-audit.sh`. It runs +`codehub analyze --force` against the same corpus under +`CODEHUB_STORE=duck` and `CODEHUB_STORE=lbug`, then compares the +`graph ` summary line emitted by each invocation. This is the +end-to-end companion to the in-memory `assertGraphParity` harness +(AC-A-7); together they pin U1 (graphHash byte-identity) from both +layers — fixtures and a real on-disk analyze. + +The script is wired into `scripts/acceptance.sh` as gate 17 (the final +gate). Sample outputs follow. + +**Dev box without the @ladybugdb/core binding (skip-clean, exit 0)**: + +```text +$ bash scripts/m7-parity-audit.sh +[m7-parity-audit][skip] @ladybugdb/core unavailable on this host; lbug leg skipped +$ echo $? +0 +``` + +The acceptance harness translates the `[skip]` line into a `[SKIP]` +gate marker; the run continues without touching the exit code. + +**Testbed environment with the binding installed (pass, exit 0)**: + +```text +$ bash scripts/m7-parity-audit.sh +[m7-parity-audit][pass] graphHash byte-identical across duck + lbug: 4f9c2a73 +$ echo $? +0 +``` + +**Regression posture (fail, exit 1)**: + +When the two backends disagree, the script retains the temp directory +and emits the divergence loudly. That output is what gate 17 escalates +into a hard `[FAIL]`: + +```text +[m7-parity-audit][FAIL] graphHash divergence — U1 invariant breach: + duck: 4f9c2a73 + lbug: 8e1d3b09 + artifacts retained at: /tmp/och-m7-audit-XXXXXX +``` + +The retained artifacts (two `.codehub/` trees, two analyze logs) are +the forensic surface for diagnosing whether the divergence comes from +column encoding, sentinel coercion, edge ordering, or a typed-finder +asymmetry. The expected workflow is to feed those two trees into +`packages/storage/src/test-utils/parity-harness.ts:assertGraphParity` +to localize the divergence to a specific node or edge before fixing +the adapter. diff --git a/packages/analysis/src/dead-code.ts b/packages/analysis/src/dead-code.ts index 52b95fa9..0e41a082 100644 --- a/packages/analysis/src/dead-code.ts +++ b/packages/analysis/src/dead-code.ts @@ -22,6 +22,7 @@ * and does not issue one query per symbol. */ +import type { NodeKind, RelationType } from "@opencodehub/core-types"; import type { IGraphStore } from "@opencodehub/storage"; export type Deadness = "live" | "dead" | "unreachable-export"; @@ -53,7 +54,7 @@ export interface DeadCodeResult { * generic reference edge (e.g. type-only usage on the Python provider) also * keeps a symbol alive. */ -const REFERRER_RELATIONS: readonly string[] = [ +const REFERRER_RELATIONS: readonly RelationType[] = [ "CALLS", "REFERENCES", "ACCESSES", @@ -238,26 +239,28 @@ function compareDeadSymbol(a: DeadSymbol, b: DeadSymbol): number { } async function fetchSymbols(store: IGraphStore): Promise { - const kindPlaceholders = [...SYMBOL_KINDS].map(() => "?").join(","); - const rows = await store.query( - `SELECT id, name, kind, file_path, start_line, is_exported - FROM nodes - WHERE kind IN (${kindPlaceholders})`, - [...SYMBOL_KINDS], - ); + // AC-A-6b: typed `listNodes({kinds: SYMBOL_KINDS})` replaces a `WHERE kind + // IN (...)` raw SELECT.
