Contributors no longer need +two repos co-located. Update via: + +```bash +git subtree pull --prefix third_party/cartographer \ + https://github.com/SimplyLiz/Cartographer.git master --squash +``` + +#### Three new MCP tools (Cartographer-backed) + +**`detectShotgunSurgery`** — Detect files that historically required simultaneous +edits across many unrelated files.

Works +without a SCIP index; complements `analyzeImpact` for unindexed repos. +``` +getBlastRadius(repo_path: "/path/to/repo", target: "src/core/engine.go", max_related: 50) +``` + +#### LIP semantic search (`GetEmbedding`) + +`internal/lip` now exposes `GetEmbedding(uri, model)` — requests a +TurboQuant-quantized embedding vector from the LIP daemon for a given file URI. +Returns `[]float32` suitable for direct dot-product similarity ranking without +dequantization. Degrades silently when LIP is not running. + +### Performance + +#### SCIP loader: lazy CallerIndex — eliminates load-time regression on small indexes + +The caller inverted index (`CallerIndex`) is now built on the first `FindCallers` +call rather than at `LoadIndex` time. This removes ~22k persistent heap objects +from the initial SCIP load on small indexes (1k docs), which were causing elevated +GC pressure and a measurable load-time regression. Medium/large indexes are +unaffected — the index is built once and cached thereafter. + +**Benchmark impact vs v8.4.0 (small, 1k docs):** load alloc count is unchanged +(~375.6k in both versions — the CallerIndex for 1k docs is not large enough to +register in alloc counts). The win is GC liveness: ~22k heap objects that would +have been promoted to old-gen are no longer live after load. No change for +medium/large. + +#### SCIP loader: `DiscardUnknown` proto decode + +Both `proto.Unmarshal` calls in the document stream parser now use +`proto.UnmarshalOptions{DiscardUnknown: true}`. This skips the reflection-based +unknown-field accumulator, reducing allocations during SCIP file decode. + +**Measured vs v8.4.0 (medium, 10k docs):** +- `B/op`: **909 MiB → 781 MiB (-14.10%)** +- `allocs/op`: **6.94M → 6.64M (-4.27%)** + +Small and large indexes show no measurable change (unknown-field savings are +proportionally smaller there). + +#### CallerIndex builder: generation-counter deduplication + +`buildCallerIndex` now reuses the `ivs` interval slice across documents (resliced +to zero, grown only when needed) and replaces the per-document `map[edge]bool` +with a generation counter (`map[edge]uint64`). Eliminates ~2k per-load allocs on +the 1k-doc case and removes all per-document map allocs on medium/large. + +#### `PopulateFromFullIndexStreaming`: two-pass streaming to prevent OOM on large repos + +`PopulateFromFullIndex` has always called `LoadSCIPIndex` which materialises the +entire `*SCIPIndex` in memory before processing a single file. On a 50k-doc +monorepo this peaks at ~15 GB and causes sustained GC pressure (observed: 485s +first run vs a consistent 83s with streaming). + +`PopulateFromFullIndexStreaming` replaces this with a two-pass strategy over +the on-disk SCIP file (via `scip.StreamDocuments`), never materialising the full +index: + +- **Pass 1**: build the `symbol→file` map — one `*scippb.Document` live at a time, + freed by GC before the next arrives. Peak live heap ≈ the symbolToFile map alone. +- **Pass 2**: stream documents again, extract deltas via the new proto-native + `extractFileDeltaFromProto` (skips all `convertDocument` allocations), write SQL + in 1000-file batches. + +`extractFileDeltaFromProto` works directly on `*scippb.Document` so there are no +intermediate `*scip.Document` / `*scip.Occurrence` / `*scip.SymbolInformation` +allocations per document per pass. + +**Benchmark vs `PopulateFromFullIndex` (50k docs, Apple M4 Pro, -count=2):** + +| | current | streaming | delta | +|---|---|---|---| +| B/op | 15.69 GB | 15.23 GB | -2.9% | +| allocs/op | 166.4M | 181.8M | +9.3% | +| time (cold) | **485s** | **83s** | **-83%** | +| time (warm) | 122s | 83s | -32% | + +The extra allocs/op come from two proto-unmarshal passes vs one (plus +`convertDocument` in the current path). The time improvement reflects reduced +GC pressure: streaming never has more than one document live at a time, so GC +never needs to scan or collect the 15 GB of live SCIPIndex data. + +#### Incremental write path: major throughput improvements (landed in v8.4.0) + +The following improvements shipped in v8.4.0 and are reflected in the v8.4.0 +benchmark baseline. Documented here for completeness: + +- **Parallel `extractFileDelta`**: GOMAXPROCS worker goroutines extract file + deltas concurrently during `PopulateFromFullIndex`. Cuts large-repo population + time by the number of available cores. +- **Batched transactions** (1000 files/tx): WAL stays bounded on 50k-file indexes + instead of growing to multi-GB. Eliminates the 10h+ timeout on large repos. +- **`PRAGMA synchronous=OFF`** during bulk load: safe because a failed full index + is always re-run from scratch. +- **Bulk INSERT for `file_symbols`**: 499-row multi-value `INSERT` batches reduce + round-trips from 50k to ~100 for large repos. +- **Hoisted prepared statements** in `ApplyDelta`: `symbol`, `callgraph`, and + `file_deps` statements prepared once per delta instead of once per file. + +**Benchmark vs v8.2.1 (v8.4.0 baseline):** +- `ApplyDelta/large` (50k files): **50s → 42s (-16%)** +- `ExtractFileDelta/50syms`: **109µs → 90µs (-17%)** +- `GetDependencies/1000files`: **7.0ms → 6.3ms (-10%)** +- SCIP allocs geomean: **-12%** (backing-slice OccurrenceRef optimization) + +#### SCIP loader: O(1) `FindCallers` via CallerIndex (landed in v8.4.0) + +`FindCallers` was O(docs × funcs × occs). It now uses an inverted map built from +Documents, making every caller lookup O(1). The index uses a sorted interval scan +with early-break for function containment and a generation-counter for +cross-document edge deduplication. + ## [8.3.0] - 2026-03-27 ### Added diff --git a/Makefile b/Makefile new file mode 100644 index 00000000..b6144073 --- /dev/null +++ b/Makefile @@ -0,0 +1,48 @@ +CARTOGRAPHER_DIR := third_party/cartographer/mapper-core/cartographer +CARTOGRAPHER_LIB := $(CARTOGRAPHER_DIR)/target/release/libcartographer.a +BIN_DIR := bin + +.PHONY: build build-cartographer build-fast test test-cartographer lint clean + +## Build CKB with Cartographer integration (default) +build: build-cartographer + @mkdir -p $(BIN_DIR) + go build -tags cartographer -o $(BIN_DIR)/ckb ./cmd/ckb/... + @echo "Built: $(BIN_DIR)/ckb (with Cartographer)" + +## Build the Cartographer static library (requires Rust toolchain) +build-cartographer: + @echo "Building Cartographer static library..." + @cd $(CARTOGRAPHER_DIR) && cargo build --release + @echo "Library: $(CARTOGRAPHER_LIB)" + +## Build without Cartographer (no Rust toolchain required — for CI and contributors) +build-fast: + @mkdir -p $(BIN_DIR) + go build -o $(BIN_DIR)/ckb ./cmd/ckb/... + @echo "Built: $(BIN_DIR)/ckb (without Cartographer)" + +## Run all tests +test: + go test ./... + +## Run all tests with Cartographer compiled in +test-cartographer: build-cartographer + go test -tags cartographer ./... + +## Lint +lint: + golangci-lint run ./... + +## Remove build artifacts +clean: + rm -rf $(BIN_DIR) + +## Check whether the Cartographer library is present +check-cartographer: + @if [ -f "$(CARTOGRAPHER_LIB)" ]; then \ + echo "Cartographer library found: $(CARTOGRAPHER_LIB)"; \ + else \ + echo "Cartographer library NOT found.

It stores facts about a project — architecture decisions, ownership, deprecated patterns, known issues — and continuously verifies them against their sources. When a source changes (a doc page, a file, a git commit), TruthKeeper cascades invalidation to all downstream facts and re-verifies them. + +**States a fact can be in:** `SUPPORTED`, `OUTDATED`, `CONTESTED`, `HYPOTHESIS` + +**Use cases alongside Cartographer:** +- "This module owns authentication" — fact stored in TruthKeeper, invalidated when `auth.rs` changes significantly +- "We deprecated `old_api.rs` in favour of `new_api.rs`" — tracked with provenance, surfaced when an AI tries to reference the old module +- Architecture decision records (ADRs) linked to the files they govern — when the file structure drifts, the ADR is flagged as `OUTDATED` + +TruthKeeper does not parse code itself. Cartographer provides the structural signals (what changed, what's coupled) that TruthKeeper's source watchers can subscribe to. + +**Does NOT do:** Structural analysis, dependency graphs, symbol extraction, or context window management. + +--- + +### TurboQuant + +**Question it answers:** _How do we store embeddings efficiently at scale?_ + +TurboQuant is an online vector quantization algorithm that compresses high-dimensional embedding vectors to low bit-widths with near-optimal distortion. It uses a two-stage approach: MSE-optimal quantization (rotation + scalar quantizers) followed by Quantized Johnson-Lindenstrauss for inner-product preservation. + +At 3.5 bits per dimension it matches full-precision performance on long-context benchmarks. + +**Relevant in this stack for:** +- TruthKeeper's semantic retrieval layer — fact embeddings stored compressed via TurboQuant +- CKB semantic search over symbol embeddings at scale + +**Does NOT do:** Anything with code structure directly — it is a compression primitive. + +--- + +### ContextCompressionEngine + +**Question it answers:** _How do we keep the conversation window useful as it grows?_ + +ContextCompressionEngine (CCE) manages the LLM message history itself — the container that holds everything the other systems produce. As a multi-turn agent session grows, earlier turns accumulate stale prose, verbose tool output, and redundant context. CCE compresses that history deterministically (no API calls, no extra LLM) while preserving code blocks, structured data, and technical identifiers verbatim. + +**How it works:** +- Multi-stage pipeline: classify → dedup → merge → summarize → size guard +- Three-tier classification: T0 (preserve — code, JSON, tables), T2 (compressible prose), T3 (removable filler) +- Deterministic sentence scoring rewards technical content (identifiers, file paths, status words) +- Size guard: if a summary would be longer than the original, the original is kept +- Fully reversible: every compression stores the original in a verbatim store; `uncompress()` restores byte-identical originals + +**Measured performance:** 1.3–6.1× compression on synthetic scenarios; 1.5× on real Claude Code sessions (11.7M chars / 8,004 messages).
