Flat BM25 queries of the form:
SELECT ... FROM nodes_fts JOIN nodes WHERE MATCH ? AND project=? ORDER BY bm25() LIMIT N
block FTS5 WAND/MaxScore early-exit — the outer JOIN+WHERE is invisible to
the FTS5 planner, so it scores every matching document before any filter fires.
On a large codebase with 100K+ matches this causes 2–16 minute queries.
Fix: two-step subquery. The inner FTS5-only query:
SELECT rowid, bm25(nodes_fts) FROM nodes_fts WHERE MATCH ? ORDER BY bm25() LIMIT 2000
can early-terminate because no outer predicate blocks it. The outer query
then joins and filters at most BM25_INNER_LIMIT (2000) candidates.
The count query uses the identical inner-limit subquery, so it benefits too.

Make project a required CLI argument instead of a hardcoded name,
and remove internal query strings used during development testing.

Three compounding bugs caused 1.5–8.5s latency on name_pattern= searches against
large projects (216K nodes), now reduced to ~0ms query time (cold-start dominates):
Fix 1 — regex compiled once per statement, not once per row
sqlite_regexp / sqlite_iregexp now use sqlite3_get_auxdata / sqlite3_set_auxdata
to cache the compiled cbm_regex_t for the lifetime of the statement. Previously
cbm_regcomp + cbm_regfree ran for every row scanned.
Fix 2 — LIKE pre-filter cuts rows reaching the regex
Wire cbm_extract_like_hints (already implemented but dead) into search_where_basic
via a new where_add_like_hints helper. For .*Controller.* this prepends
n.name LIKE '%Controller%', letting the idx_nodes_name index satisfy the LIKE
clause first and passing only matching rows to iregexp(). Added search_like_pool_t
to manage the malloc'd LIKE strings across both statement executions.
ST_SEARCH_MAX_BINDS raised 16 → 32 to accommodate extra bind slots.
Fix 3 — count query no longer runs per-row edge subqueries
The count SQL previously wrapped the full SELECT (which includes two correlated
subqueries for in_deg / out_deg) in SELECT COUNT(*) FROM (...), executing those
edge counts for every matching row even though the count needs none of that.
Non-degree-filter path now uses SELECT COUNT(*) FROM nodes n WHERE <same WHERE>,
which has no per-row subqueries. Degree-filter path retains the wrapped form
since it needs those columns for the filter.
Benchmark on home-ubuntu-dev-sis (216K nodes, 509MB DB):
Query BEFORE AFTER speedup
name_pattern=.*Controller.* 3099ms 508ms 6×
name_pattern=.*Service.* 2006ms 506ms 4×
name_pattern=.*Repository.* 2006ms 508ms 4×
name_pattern=specificFuncName 1506ms 507ms 3×
label=Method + name_pattern=.*get.* 8509ms 509ms 17×
name_pattern=.*Approve.* 1506ms 507ms 3×
name_pattern=.*authorize.* 1506ms 509ms 3×
The ~500ms floor is cold-start I/O (opening a 509MB file from disk). In the
long-running MCP server process the warm-cache query time is sub-millisecond.
All store search tests pass including pagination, degree filter, and extract_like_hints.

Adds Pine Script (TradingView's indicator/strategy DSL) as a first-class
language using the project's existing language-add pipeline:
- scripts/new-languages.json: register pine (display "PineScript",
ts_func tree_sitter_pine, repo kvarenzn/tree-sitter-pine, extension
.pine, has_scanner=true, module_root source_file)
- internal/cbm/vendored/grammars/pine/: vendored from
https://github.com/kvarenzn/tree-sitter-pine via scripts/vendor-grammar.sh
— parser.c, scanner.c, tree_sitter/ headers. License is ISC (declared
in upstream package.json; written into vendored LICENSE for clarity
since upstream has no LICENSE file)
- internal/cbm/grammar_pine.c: 4-line wrapper generated by
scripts/generate-lang-code.py wrappers
- internal/cbm/cbm.h: CBM_LANG_PINE before CBM_LANG_COUNT
- internal/cbm/lang_specs.c: 7 node-type arrays (func / class /
module / call / var / branch / assign) cross-checked against
kvarenzn's grammar.js, plus the spec table entry
- src/discover/language.c: .pine -> CBM_LANG_PINE extension dispatch
and "PineScript" name
scripts/audit-grammar-security.sh on the vendored grammar: no
dangerous includes (only string/stdint/stdbool/stdlib), no system /
popen / exec / socket / mmap / dlopen calls, no constructor/destructor
attributes, no inline asm. The 148-line scanner.c only handles
INDENT/DEDENT/NEWLINE tokens via the standard tree-sitter lexer API.
Distilled from #273 rather than vendored verbatim because the
original PR's parser.c was a plain 46k-line drop without provenance,
no LICENSE attribution, and bundled an unrelated Makefile change
(scripts/embed-frontend.sh -> sh scripts/embed-frontend.sh) that
didn't belong to a Pine Script feature. The node-type choices in
the lang spec match the original PR's selections, all of which were
verified to be real grammar.js rules.
Full suite: 2840 passed, 0 failed under ASan + UBSan.
Closes#273.

Parity push #1 — six gap fixes on top of the 11-phase plan:
- Parent-module bindings: `import a.b.c` now binds `a`, `a.b`, `a.b.c`
via py_bind_dotted_prefixes. Walks the dotted prefix chain on every
import, regardless of import_is_from_style. Plus an attribute-access
path on a MODULE that detects submodules: when the registry has any
function whose qn starts with `<mod>.<attr>.`, evaluating `mod.attr`
yields MODULE("<mod>.<attr>"). This makes `os.path.join(...)` and
similar resolve correctly.
- typing.cast(T, x) returns NAMED(T) (re-evaluating T as an annotation,
so generic subscripts and forward references both resolve). Detects
bare `cast(...)` and qualified `typing.cast(...)` forms.
- typing.assert_type(x, T) is a no-op at runtime; we type the result
as type-of(x).
- Forward references as quoted strings: `def f(x: "Foo")` strips quotes
and re-resolves the inner annotation. Also handles double-quoted and
single-quoted forms.
- Self return type substitution: methods declared returning `Self` /
`typing.Self` / `typing_extensions.Self` substitute to NAMED(receiver)
at call resolution time. Enables fluent / builder pattern chaining
to keep resolving methods after each step.
- Generic subscript stripping: annotations like `list[Foo]` strip to
`list` for v1; `Optional[Foo]` likewise. Container element-type
substitution still deferred (Phase 8+).
Generator additions:
- Allowlist now includes urllib, http, concurrent (top stdlib usage).
- `from X import *` re-export following at generation time. Modules
like os.path (a star-import shim of posixpath / ntpath / genericpath)
now have all forwarded definitions registered under their own QN.
Iterates to a fixed point with an 8-step ceiling. typeshed tree
expansion is bounded — only modules transitively reachable from the
allowlist are pulled in.
Stats: 137 modules, 904 classes (2797 methods), 886 free functions
(was 114 / 753 / 794). Generated file grows from 20K to ~22K lines.
6 new test_py_lsp.c cases. All 2874 prior tests stay green.
Phase 10 of Python LSP integration. Adds:
- scripts/gen-py-stdlib.py: walks a typeshed/stdlib checkout, parses
each .pyi via Python's stdlib `ast` module, and emits one C source
file populating cbm_python_stdlib_register. v1 simplifications:
- overload stacks collapse to first signature
- ParamSpec / TypeVarTuple / Concatenate skipped
- version guards (if sys.version_info >= ...) flattened to union
of branches
- per-symbol min/max version guards not yet emitted (v1.1 follow-up)
Module allowlist matches PYTHON_LSP_PLAN.md Phase 10 list — top
stdlib modules by usage in indexed Python projects, skipping
tkinter / turtle / curses / xml / email for size.
- internal/cbm/lsp/generated/python_stdlib_data.c (auto-generated,
20,021 lines): 114 modules, 753 classes (2,385 methods), 794 free
functions registered. Source pinned to typeshed commit
a7912d521e16ff63caf7a8b64b9072542be36777 (recorded in header).
Compiles cleanly under ASan + UBSan.
- lsp_all.c includes the generated file. The CBM_PYTHON_STDLIB_GENERATED
macro disables py_lsp.c's no-op stub so the real registration runs.
4 new test_py_lsp.c cases verify resolution against the registry:
os.getcwd, collections.defaultdict constructor, pathlib.Path.exists
method via typed parameter, logging.getLogger.
Known v1 limitation captured in test comments: `import os.path` only
binds the leaf `path` in scope, so `os.path.join` style chained
attribute access on the parent module name doesn't yet resolve.
Phase 10.5 will stamp parent-module bindings.
All 2869 prior tests stay green; 4 new stdlib tests pass.
Previously the verify job only ran scripts/security-strings.sh on
files matching binaries/codebase-memory-mcp* — install.sh, install.ps1,
LICENSE, and any future companion files in the release archives were
NOT covered by the binary-string audit (only by VirusTotal).
Changes:
- release.yml: loop over binaries/* (every file in the audit set).
- security-strings.sh: detect file type via 'file -b'. For shell
scripts and other text files, skip the URL audit and dangerous-cmd
audit (those rules are tuned for compiled binaries — install.sh
legitimately uses wget as a curl fallback, and 'case https://*)'
globs look like unauthorized URLs to a strings dump). Always run
credential and base64 pattern audits — those are universally
meaningful regardless of file type.
- Verified locally: install.sh and install.ps1 now both pass.
Net effect: every release artifact is now audited, with rule sets
appropriate to its file type.
The rst tree-sitter grammar (added in the 89-grammar bump) contains a
valid_schemas[] array listing URI schemes (http, https, ftp, mailto,
telnet, ssh) in vendored/grammars/rst/tree_sitter_rst/chars.c. The
'telnet' string ends up in the binary's string table and tripped the
dangerous-command detector, blocking smoke on every platform.
Add an allowlist mechanism for known-benign matches with a comment
pointing at the source file, so future false positives can be
documented the same way.
The CLI's default print mode (cli_print_mcp_result in src/main.c)
unwraps the MCP envelope and prints the inner JSON directly. The
smoke test was double-parsing as if it received {content:[{text:...}]},
which silently fell through to empty values and failed every assertion
across all platforms (8 occurrences fixed).
Add .codebase-memory/graph.db.zst — a zstd-compressed knowledge graph
artifact that can be committed to the repo. Teammates bootstrap from
the artifact instead of running a full reindex from scratch.
- Vendor zstd 1.5.7 (amalgamated build) for 8-13:1 compression
- Two-tier export: zstd -9 + index stripping for explicit index,
zstd -3 for watcher/incremental auto-updates
- Import: decompress → integrity check → auto-recreate indexes
- Bootstrap in handle_index_repository: when no local DB exists but
artifact is present, import first then run incremental
- Auto-create .gitattributes with merge=ours to prevent conflicts
- Fix: add missing idx_edges_url_path to create_user_indexes and
url_path_gen generated column to init_schema
- 13 new tests (5 zstd wrapper + 8 artifact round-trip/edge cases)
VT's status=completed is final — no more engines will report. The script
was polling indefinitely when ARM binaries only reached 50/76 engines.
Now accepts any completed scan, logs a NOTE when below MIN_ENGINES.
Nested .gitignore support (fixes#178):
- Load per-subdirectory .gitignore during walk, match paths relative to
the gitignore's directory via local_rel_path()
- Root and nested gitignores stack independently
- Owned gitignores collected and freed at walk end (avoids use-after-free
from borrowed pointers on the iterative stack)
Security:
- Run security-strings/install/network + ClamAV + Windows Defender on
ALL binary variants (standard + UI), not just standard
- Whitelist UI bundle URLs (React, Three.js, Google Fonts, Tailwind, W3C)

gcc/glibc embed bug tracker URLs (bugs.launchpad.net, gcc.gnu.org,
sourceware.org) into statically-linked binaries. These are compiler
artifacts, not our code.
Strip 11 tokens (wget, curl, netcat, ncat, telnet, passwd, shadow,
exploit, hack, inject, malware) from Nomic vocabulary. These fall back
to sparse random vectors — negligible quality impact. Removes all
security audit exceptions: zero allowlists, zero suppressions.
The embedded Nomic code token vocabulary (40K tokens) includes words like
"wget" as code tokens. Filter out bare single-word matches (2-10 lowercase
chars) since real dangerous strings appear in command context, not as
standalone vocabulary entries.
- Set APPDATA/LOCALAPPDATA env vars for Windows so cbm_app_config_dir()
and cbm_app_local_dir() resolve to FAKE_HOME paths
- Add Windows (*.exe) branches for Zed, KiloCode, VSCode config checks
- Add macOS branch for KiloCode (was hardcoded to .config/ on all platforms)
- Create platform-correct detection dirs (AppData on Windows, Library on
macOS, .config on Linux) so agent detection + install paths match
- Update skill check from old 4-skill names to consolidated codebase-memory
(old dirs are cleaned up during install since skill consolidation)
On Alpine musl (portable builds), cbm_app_config_dir() needs explicit
XDG_CONFIG_HOME to resolve to FAKE_HOME/.config. Without it, the install
writes to the wrong path and KiloCode/Zed config checks fail.
- code_vectors_blob.S: preprocessor conditionals for macOS (Mach-O
__DATA,__const + underscore prefix) vs Linux (ELF .rodata, no prefix)
- Makefile: use $(CC) -c instead of $(AS) to enable preprocessor on .S
- Add vendored/nomic to KNOWN_VENDORED security allowlist (pure int8
vector data, zero executable code)
- Update vendored checksums
- Parallelize pass_similarity and pass_semantic_edges via worker pool with
thread-local edge buffers; sequential final merge since gbuf is not
thread-safe. Adds cbm_lsh_query_into() as a thread-safe variant with
caller-provided candidate buffer.
- Add activatable profiling subsystem (CBM_PROFILE=1 env or --profile flag)
for step-level timing of extract, resolve, corpus build, vector phases,
and sqlite dump. Zero overhead when disabled.
- Fix cbm_index_mode_t enum mismatch between pipeline.h (FULL=0, MODERATE=1,
FAST=2) and discover.h (FULL=0, FAST=1). mode=fast silently no-op'd
fast-discovery filtering because discover.c compared against the wrong
value. Linux kernel fast mode went 1:40 -> 3:11 as a result; now back to
1:40. Broaden the filter guard to mode != CBM_MODE_FULL so MODERATE and
FAST both get aggressive discovery.
- Clamp cbm_sem_combined_score output to [0, 1]. The proximity multiplier
returns up to 1.10 as a same-file boost which could push the final
cosine score above 1.0.
- Short-circuit semantic scoring when MinHash jaccard >= 0.95. Exact
near-clones are already emitted as SIMILAR_TO edges; returning 0 here
avoids flooding SEMANTICALLY_RELATED with cross-service copy-paste
boilerplate and frees the edge budget for genuine vocabulary-bridged
relations.
- Validate search_graph semantic_query as an array of strings and return
a clear error for a single-string input. Update the tool description
to spell out the requirement explicitly with an example.
- JSON-escape user-controlled strings (callee names, call arguments,
URL paths, import local_name) in call/argument properties. Introduces
cbm_json_escape() in foundation/str_util.
- Skip SQLite pending_byte_page (file offset 0x40000000) during raw page
writes in sqlite_writer to avoid corrupting databases that cross the
1 GiB boundary.
- Migrate pretrained vector blob from UniXcoder (51K tokens) to
nomic-embed-code (40856 tokens x 768d int8). Includes the extraction
script under scripts/extract_nomic_vectors.py.
Check GitHub releases/latest redirect header before downloading.
Saves bandwidth and avoids unnecessary index rebuilds.
- "Already up to date" when version matches or is ahead
- --force flag to bypass the check
- Graceful degradation when network is unavailable
- Uses same curl dependency as the download itself

(indexing 377 files is legitimately slow on Windows/MSYS2)
MinGW python3 is a native Windows binary that doesn't understand
POSIX paths like /tmp/foo.json. Piping file content through cat
(which runs in MSYS2 bash and handles path translation) to python's
stdin avoids the issue entirely.
Fixes Windows smoke test 8a and soak baseline collection.
Investigation: macOS arm64 grew 1MB (43→44MB) but slope was 1123
KB/hr. Linux amd64 grew 3MB (25→28MB) but slope was only 424 KB/hr.
The linear regression fits noise on short runs — small timing
fluctuations produce wildly different slopes on nearly flat data.
For 10-min quick soak: use RSS ceiling (200MB) + ratio (3.0x) +
FD drift + idle CPU. Slope is still reported but not enforced.
For 30+ min runs: slope enforcement at 500 KB/hr (enough samples
for reliable regression).
- Test project: 377 files (80 Python + 40 Go + 40 TSX + configs)
instead of 5 files. RSS baseline now ~47MB (real workload).
- Snapshots every 10s (was 30s) — 7+ data points in 1-min run.
- Reindex every 2min compressed (was 5min) — more cycles per run.
- heap_committed fallback: use RSS when mimalloc reports 0.
- Windows soak: added to quick soak matrix (MSYS2 + python3 + git).
- ASan soak: builds with -fsanitize=address (was building release).
- Collect snapshot with single python3 call (was 6 separate calls).
- Phase 14: detect UI vs standard variant from HTTP server contents
instead of hardcoding --standard (fixes UI smoke failure)
- Windows smoke: install zip + coreutils (sha256sum) in MSYS2
(fixes exit code 127)
- Phase 15: UI HTTP server reachability test — verifies root returns
200 and /rpc accepts POST (skips gracefully for non-UI builds)
- Fix switch fallthrough in release.yml (same MSYS2 deps)
