feat: Rust rewrite foundation — ADR-0003, Phase 0 scaffold, plan#34
Merged
Conversation
Record the decision to rewrite @pleaseai/csp from TypeScript/Bun to Rust. Captures the four motivations (single-binary distribution, indexing/embedding performance, ecosystem fit, maintainer preference), verified Rust crate mapping (model2vec-rs, rmcp, tree-sitter, ignore, clap), the Biome-style multi-channel distribution strategy that preserves the bunx entrypoint, and the decision to defer the JS library API behind a future napi-rs seam. Status: Proposed.
Set up the Rust rewrite skeleton alongside the TypeScript tree: - Cargo workspace with crates/csp (library seam) and crates/csp-cli (the `csp` binary), pinned to Rust 1.94.1 via rust-toolchain.toml. - workspace.dependencies pre-declares the ADR-0003 crate menu (model2vec-rs, tree-sitter, ignore, rmcp, clap, serde) for phase-by-phase wiring. - clap CLI stubs all README subcommands (search/index/find-related/mcp/init/ savings/clear); each bails with an ADR-0003 reference until its phase lands. - Rust CI workflow (fmt/clippy -D warnings/test), reusing the SHA-pinned actions/checkout and the runner's rustup honoring rust-toolchain.toml. - release profile tuned for single-binary distribution (lto/strip). The TypeScript src/ remains source of truth until Rust reaches parity.
Track for ADR-0003 Phases 1-7 (Rust rewrite). spec.md captures scope, the behavioral-equivalence success criteria (SC-001..005), and the JS library API deferral; plan.md breaks the work into 24 tasks across 7 phase sections with golden-fixture verification and STOP conditions on the high-risk ports (model2vec-rs embeddings, rmcp MCP parity, cache format).

Code Review
This pull request scaffolds Phase 0 of rewriting the @pleaseai/csp tool from TypeScript to Rust, establishing a Cargo workspace with a core library (csp) and a CLI binary (csp-cli). It also includes the architectural decision record (ADR 0003), a detailed migration plan, and toolchain configurations. The review feedback recommends fixing a typo ('невали드' to 'invalid') in the plan document and deriving standard traits (Debug, PartialEq, Eq) on the ContentFilter enum in the CLI crate for better idiomatic Rust design.

TIP This summary will be updated as you push new changes.
Phase 1 leaf modules ported into crates/csp with behavioral equivalence verified against the TypeScript test vectors (32 tests): - types: ContentType/CallType enums, Chunk, chunk_location, chunk_to_dict, chunk_from_dict (untrusted-JSON validation replacing the TS TypeError guards). - tokens: identifier-aware tokenizer; the camelCase splitter is reimplemented as a state machine because the Rust regex crate lacks the upstream CAMEL_RE lookahead — it reproduces the regex match sequence exactly. - utils: is_git_url (scheme + hand-rolled scp lookahead) and resolve_chunk. cargo fmt / clippy -D warnings / test all green. Refs #33
…007, T006 partial) Add the crates/csp ranking module: - weighting: resolve_alpha (adaptive alpha 0.3 symbol / 0.5 NL), honoring an explicit Some(0.0) vs None like the TS null/undefined distinction. - penalties: file_path_penalty (test/barrel/.d.ts/compat/examples patterns) and rerank_top_k with file-saturation decay and early-exit, keyed by chunk index. - boosting::is_symbol_query (SYMBOL_QUERY_RE) — consumed by weighting; the rest of boosting (apply_query_boost, definition detection) follows in T006. Score maps use IndexMap<usize, f64> (insertion-ordered, chunk-index keys) as the Rust analogue of the TS Map<Chunk, number>. Penalty regexes stay Unicode-aware (negated classes can't disable Unicode in a string Regex). 58 equivalence tests pass; fmt / clippy -D warnings / test green. Refs #33
Add crates/csp/src/indexing/sparse.rs:
- enrich_for_bm25: content + stem×2 + last 3 dir parts, POSIX-normalized.
- selector_to_mask: index selector → 0/1 mask, out-of-bounds dropped.
- Bm25Index::{build, get_scores}: minimal Okapi BM25+ (k1=1.5, b=0.75) with
Lucene/Robertson IDF and optional weight mask.
Two parity details reproduced exactly: per-addition f32 rounding (matching the
TS Float32Array accumulation) and first-appearance unique-term ordering — both
affect the order-sensitive f32 scores. save/load (filesystem) is deferred to
the Phase 3 cache task (T014); the state already derives serde.
73 equivalence tests pass; fmt / clippy -D warnings / test green.
Refs #33
Complete the boosting module: - apply_query_boost: symbol-definition boosts (with non-candidate stem scan), embedded-symbol half-strength boosts, and NL stem-match boosts. - boost_multi_chunk_files: per-file coherence boost of the top chunk. - chunk_defines_symbol / definition_pattern: language definition detection via fancy-regex, since the upstream (?<=\s) lookbehind is unsupported by the regex crate; patterns transcribed verbatim and cached per symbol name. - supporting helpers (extract_symbol_name, stem_matches, count_keyword_matches, path stem/parent helpers) all matched to the TS semantics. This completes Phase 1 (pure core). 88 equivalence tests pass across tokens, types, utils, ranking (weighting/boosting/penalties), and BM25; fmt / clippy -D warnings / test green. Refs #33
…mplete Add the crates/csp/src/chunking module: - core: the merge algorithm (merge_node_inner/merge_node/merge_adjacent_chunks) generic over an AstNode trait (unit-tested with mock nodes, later driven by tree_sitter::Node), chunk_lines (CRLF-aware, character offsets), constants (RECURSION_DEPTH=500, MIN_CHUNK_SIZE=50), and the chunk()/is_supported_language contract. - source: chunk_source with 1-indexed line numbering (only \n counts) and the AST-vs-line-fallback selection. At parity with the current TS, is_supported_language is a false stub and real tree-sitter grammar parsing activates with the language map (T012); until then callers use the line fallback. 115 equivalence tests pass; fmt / clippy -D warnings / test green. Refs #33
Add crates/csp/src/indexing/files.rs: - EXTENSION_TO_LANGUAGE: the full ~330-entry extension→language map, transcribed verbatim (.txt→vimdoc intentionally omitted as upstream). - DOC/CONFIG/DATA language sets and the derived CODE set (ALL − DOC − CONFIG − DATA). - detect_language: case-insensitive final-suffix lookup, dotfile-aware (.gitignore → None), POSIX + Windows separators. - get_extensions: sorted, de-duplicated union of extensions by content type with user extensions appended. This populates ALL_LANGUAGES (the future driver for tree-sitter activation in chunking, currently a separate stub at TS parity). 129 equivalence tests pass; fmt / clippy -D warnings / test green. Refs #33
Add crates/csp/src/indexing/file_walker.rs using the `ignore` crate:
- DEFAULT_IGNORED_DIRS (.csp/ replacing semble's .semble/).
- load_ignore_for_dir: merge .gitignore + .cspignore (gitignore first),
skipping blanks/comments, preserving source order.
- is_ignored: maps Gitignore::matched -> Match::{None,Ignore,Whitelist} onto the
upstream npm `ignore` {ignored,unignored} contract. Reproduces the
negation-with-extension bypass (found) via per-pattern matchers, gated on a
precomputed has_negated_ext_pattern fast-path. Multi-spec, outer-state-
preserving (later matches override earlier).
- walk / walk_files: recursive, symlink-skipping, name-sorted, with the
extension allowlist (case-insensitive) and the found bypass.
17 filesystem integration tests (tempfile dev-dep) mirror the TS suite; 146
tests total pass. fmt / clippy -D warnings / test green.
Refs #33
Add Bm25Index::{save,load} persisting to dir/bm25.json. The on-disk shape
matches the TS serialization exactly — camelCase keys (version, numDocs,
avgDocLength, docLengths) and [[term, postings]] / [[term, df]] entry arrays —
via a dedicated Bm25Serialized struct, so a Rust-written index is loadable by
the TS implementation and vice versa.
Tests: score round-trip after save/load, TS-compatible JSON key assertions, and
missing-file error. 149 tests total pass; fmt / clippy -D warnings / test green.
Refs #33
Add crates/csp/src/indexing/cache.rs with the pure cache pieces:
- resolve_cache_dir: sha256 cache key over a field-ordered {sourceId, content,
ref} JSON payload (byte-parity with the TS JSON.stringify), keyed dir
<home>/index/<key-32>. Adds ContentType::as_str for the lowercase form.
- resolve_index_root: <home>/index, parent of every cache leaf.
- compute_content_hash: order-independent sha256, folding "<utf16-len>:<path>"
prefixes + raw content bytes (string/bytes hash identically).
- ensure_cache_dir: create the ~/.csp -> index -> leaf chain at 0700, tightening
pre-existing dirs (Unix; no-op elsewhere).
- clear_index_cache: canonicalize the target and require it be the direct
`index` child of the resolved home, rejecting symlink escapes (AC-015).
load_or_build_index orchestration is deferred to T016 (it composes CspIndex,
which needs the dense index, T013). Adds the sha2 dependency. 168 tests total
pass; fmt / clippy -D warnings / test green.
Refs #33
The TS dense.ts ships a STUB Model2Vec (deterministic hash-seeded vectors),
not the real model — its TODO(dense) is still open. Since the behavioral oracle
is the TS test suite, reproduce the stub bit-for-bit:
- fnv1a over UTF-16 code units (u32 wrapping + Math.imul semantics).
- mulberry32 PRNG (exact u32 ops; JS `t ^= t + imul` = wrapping-add then xor).
- stub_embed: Box-Muller with the precise f64<->f32 narrowing (store g as f32,
accumulate norm from the pre-narrow f64 g, final scale reads f32 back).
- Verified against golden vectors captured from the TS functions
(fnv1a("hello")=1335831723; stub("hello",8) / stub("foo",4) exact f32).
This resolves the plan's embedding-parity STOP: both implementations use the
stub, so no model weights are needed for parity. Real model2vec-rs integration
is a separate future task (out of scope for oracle parity).
Also ports SelectableBasicBackend: cosine query with optional selector pool,
dim validation, and vectors.bin/args.json save/load. 187 tests total pass;
fmt / clippy -D warnings / test green.
Refs #33
Phase 3 complete. create_index_from_path walks the resolved extensions, chunks each file via chunk_source, embeds the chunks, builds the BM25 index over tokenize(enrich_for_bm25(chunk)), and wraps embeddings in a SelectableBasicBackend. Honors MAX_FILE_BYTES (1 MB skip), stores chunk paths relative to display_root when set, and errors when no chunks are produced. 5 filesystem tests mirror create.test.ts (small TS file, no-supported-files error, extensions override, MAX_FILE_BYTES skip, subdir descent). 192 tests total pass; fmt / clippy -D warnings / test green. The cache.ts load_or_build_index orchestration folds into T018 (it needs CspIndex.save / loadFromDisk). Refs #33
Add crates/csp/src/search.rs: semantic + BM25 -> per-list RRF (k=60) ->
alpha-weighted combine -> optional rerank. Trait-based over EmbeddingModel /
VectorBackend / SparseBackend (implemented for the real dense/sparse types,
mockable in tests).
Parity: search.ts still uses inline ranking stubs (apply_query_boost = identity;
rerank_top_k = file-saturation decay only, ignoring penalisePaths) with a
TODO(integration) to wire ranking/*. To match the TS oracle, search.rs
reproduces those stubs exactly — the fuller ranking::{apply_query_boost,
rerank_top_k} (T006/T007) stay ported but unwired, mirroring TS.
boost_multi_chunk_files is the shared ranking implementation.
Verified against search.test.ts: sort_top_k, rrf_scores (1/61 first rank),
distance->similarity, BM25 zero-exclusion + selector mask, alpha=1/alpha=0
ordering, startLine-stable tie-break, multi-chunk file boost. 209 tests total
pass; fmt / clippy -D warnings / test green.
Refs #33
Phase 4 complete. crates/csp/src/indexing/index.rs:
- CspIndex::{from_path, from_git, search, find_related, stats, save,
load_from_disk, new}. from_git shallow-clones into a 0700 tempdir
(std::process::Command, GIT_TERMINAL_PROMPT=0), rejects dash-prefixed refs
(flag injection, CWE-88), re-roots at the URL, and auto-cleans on drop.
- search applies language/path filters as a selector, short-circuiting to [] on
blank query / top_k<=0 / empty index / empty selector.
- save writes chunks.json + bm25.json + vectors.bin + args.json + manifest.json;
load_from_disk validates artifacts, schema version, and the manifest
(parse_manifest trust-boundary checks), then dim-aligns the query model.
- load_or_build_index: the T015-deferred cache.ts orchestration —
resolve_cache_dir -> ensure_cache_dir -> content-hash reuse-or-rebuild, keyed
by URL+ref for git sources. Miss/hit/invalidate verified.
Adds the IndexStats type; promotes tempfile to a normal dependency. 229 tests
total pass (incl. a real round-trip); fmt / clippy -D
warnings / test green.
Refs #33
Add crates/csp/src/stats.rs:
- BucketStats::add (saved clamped to >= 0 via saturating_sub).
- save_search_stats: best-effort JSONL append ({ts, call, results,
snippet_chars, file_chars}); snippet_chars uses UTF-16 length (JS .length
parity); file_chars deduplicated per unique path.
- clear_savings: deletes (not truncates) the file.
- build_savings_summary: Today / Last 7 days / All time buckets via UTC
YYYY-MM-DD (Hinnant civil-from-days, no date dependency), lexicographic
date compare, NaN-ts and malformed-line skipping. now injected for testable
bucketing.
- format_savings_report: ANSI headline + By Period (+ By Call Type when
verbose); header reads 'Csp Token Savings'; 'No stats yet' when absent.
14 tests cover bucket math, record format, dedup, time buckets, NaN skip,
clear, report header, and known UTC dates. 243 tests total pass; fmt /
clippy -D warnings / test green. CLI wiring of `csp savings` lands in T019.
Refs #33
Phase 5 complete. Port src/cli.ts onto the clap CLI:
- search / find-related: load via the on-disk auto-cache (load_or_build_index)
or an explicit --index, then emit { query, results } JSON. Adds
csp::utils::format_results producing the snake_case wire dict (content,
file_path, start_line, end_line, language, location) — distinct from the
camelCase ChunkDict used for persistence.
- index --out: build (from_path/from_git) and save a pre-built index.
- savings --verbose, clear all|index|savings: drive the telemetry + caches.
- init --agent/--force: write .{agent}/agents/csp-search.md (.github for
copilot) from one of 10 agent templates embedded via include_str!
(crates/csp-cli/agents/, copied from src/agents).
- mcp: stubbed pending T021.
Pure handlers (search_output, find_related_output, run_init, resolve_content,
agent_path) are unit-tested. 243 lib + 8 CLI tests pass; fmt / clippy -D
warnings / test green.
Refs #33
Port the verifiable core of src/mcp/server.ts into csp::mcp: - IndexCache: session cache keyed by git-URL@ref or absolutized path, LRU-bounded to 10, evict, build-failure-not-cached, git-vs-path routing through an injectable LoadOrBuild seam (default: the on-disk load_or_build_index). - get_index: source-safety layer — rejects ssh://, git://, file:// (only https://, http://, or local paths), and the no-source case, with descriptive errors. - search / find_related tool handlers: same format_results JSON + error strings as the CLI, transport-agnostic. 14 tests mirror server.test.ts (reuse/evict/LRU/routing/failure, URL-safety, handler JSON). 255 lib + 8 CLI tests pass; fmt / clippy -D warnings / test green. The rmcp stdio transport is intentionally NOT wired: its on-the-wire schema and stdio behavior can't be verified without an MCP client, and the plan's STOP requires that verification before claiming protocol parity. `csp mcp` reports the core is ready and the transport is pending verification. Refs #33
Phase 7 distribution infrastructure, authored without disrupting the live TypeScript release pipeline (release-please.yml): - T022: .github/workflows/release-rust.yml — cargo cross-compile matrix for darwin arm64/x64 (native), linux x64/arm64-gnu + x64-musl, windows-x64. SHA-pinned actions; emits csp-<target> + .sha256 matching the TS pipeline's asset names. workflow_dispatch only, so it does not override the live release. - T023: npm/ wrapper (Biome model) preserving bunx @pleaseai/csp — npm/csp with a Node launcher (bin/csp.js: platform + libc resolution -> exec the binary) and optionalDependencies on per-platform packages; npm/scripts/generate- platform-packages.mjs materializes those packages (os/cpu/libc constraints) from release assets for npm publish --provenance. - T024: the existing Homebrew formula generator already consumes the csp-<target> names release-rust.yml produces (works unchanged post-cutover); user-facing READMEs left accurate to the current TS distribution. These are CI/publish-gated and cannot be verified locally. Cutover to the Rust binaries is a maintainer decision gated on full runtime parity (see plan Progress log for the checklist). Rust workspace remains green (255 lib + 8 CLI tests); JS + YAML syntax-checked. Refs #33
Phase 6 complete. Add crates/csp-cli/src/mcp_server.rs — an rmcp 1.7 stdio
server that exposes the search / find_related tools over the live MCP protocol,
delegating to the transport-agnostic csp::mcp handlers:
- #[tool_router] + two #[tool]s (typed Parameters<T> with schemars schemas) +
#[tool_handler(router = self.tool_router)]; ServerInfo advertises
SERVER_INSTRUCTIONS and the tools capability.
- run_mcp builds a tokio runtime and serves over stdio(); csp mcp invokes it.
- IndexCache switched from Rc to Arc<CspIndex> so it is Send and shareable
across the async server's tasks (CspIndex is already Send + Sync).
- Add rmcp (server, macros, transport-io), tokio, schemars, serde deps.
Verified on the wire by driving JSON-RPC into the built binary:
- initialize -> protocol version, tools capability, our instructions;
- tools/list -> search + find_related with correct input schemas
(required query / file_path+line, optional repo / top_k);
- tools/call search -> indexed a temp dir on demand and returned the
snake_case {query, results:[{chunk, score}]} wire JSON as a CallToolResult
text payload (isError:false) — matching the TS MCP contract.
This resolves the last open STOP on T021. 255 lib + 8 CLI tests pass;
fmt / clippy -D warnings / test green.
Refs #33
…la (T022-T024) Convert the Phase 7 scaffolding from 'authored' to 'executed & verified' for everything that does not require a publish credential: - T022: built the release binary for the host (x86_64-apple-darwin, stripped+lto) and cross-compiled aarch64-apple-darwin; both smoke-tested (--version + a real search). Linux musl/gnu + Windows need native-runner cross-linkers (the matrix uses native runners for exactly this reason). - T023: made generate-platform-packages.mjs partial-matrix-tolerant (skip a missing asset with a warning, pin only generated targets in the wrapper's optionalDependencies). Ran it against the built binaries and verified the launcher end-to-end in a sandbox node_modules — resolve + exec, argv forwarding, and a clean exit-1 when the platform package is absent (the exact bunx/npx path). npm/dist/ is gitignored (release artifact). - T024: validated the generated Homebrew formula's Ruby syntax (ruby -c, with the workflow's sed placeholders filled). The only steps left are publish side-effects that require secrets + a real release tag (GitHub Releases upload, npm publish --provenance, homebrew-tap push) — not implementation, and not runnable locally.

In @.github/workflows/release-rust.yml:
- Line 45: The macos-13 runner label is retired and will cause the job to fail
to schedule on GitHub Actions. Replace the os value of macos-13 with
macos-15-intel to provide Intel (x86_64) architecture support using the current
supported runner label.- Around line 118-121: The Upload to release step directly interpolates
inputs.tag into the run command, creating a shell injection vulnerability. To
fix this, add inputs.tag as an environment variable (TAG) in the env section
alongside GH_TOKEN, then add validation logic in the run command to check that
the tag matches a valid format (typically a semantic version pattern) before
passing it to the gh release upload command. Replace the direct interpolation of
inputs.tag in the gh command with the environment variable reference.In @.github/workflows/rust.yml:
- Around line 9-21: The path filter strings in both the push and pull_request
sections use quoted scalars (single quotes around strings like 'Cargo.toml',
'Cargo.lock', etc.) which violate the repository's YAML linter rule
yaml/plain-scalar. Remove the single quotes from all the path strings in both
the push: paths and pull_request: paths sections to convert them to plain
scalars, as these filenames and paths do not contain special characters
requiring escaping.- Around line 34-36: The Checkout code step in the rust.yml workflow is using
the actions/checkout action but is not disabling persisted credentials. Add a
with configuration section to the actions/checkout step that sets
persist-credentials to false. This prevents Git credentials from being persisted
in the runner since all subsequent workflow steps (format check, clippy, test)
are read-only operations that do not require Git credentials, thereby
implementing the principle of least privilege.In
@Cargo.toml:
- Around line 8-36: The workspace configuration in Cargo.toml has formatting
violations preventing CI from passing. In the members array on line 8 and
throughout the workspace.dependencies section (lines 21-36), reformat to comply
with the repo's TOML linter rules: ensure array formatting follows the linter's
array style rules, add proper padding lines between dependency pairs in the
workspace.dependencies block, and remove excessive spaces in front of inline
comments to follow the no-multi-spaces rule. Adjust all spacing and line breaks
in these sections to match the enforced TOML style configuration.In
@crates/csp-cli/Cargo.toml:
- Around line 4-25: The Cargo.toml file in the csp-cli crate has TOML formatting
violations that are blocking CI. Fix the manifest by adding appropriate blank
lines between the workspace metadata fields and the [[bin]] section, ensuring
proper padding-line-between-pairs formatting between logical sections. Verify
that all array brackets in the [[bin]] and dependency sections follow proper
array-bracket-spacing conventions, and ensure array elements in the dependencies
sections follow consistent formatting without multi-space padding around the
equals signs and braces. Review the entire manifest structure from the workspace
metadata through the dev-dependencies to ensure it adheres to TOML linting
standards.In
@crates/csp-cli/src/main.rs:
- Around line 94-96: The git_ref field defined with the --ref argument in the
argument struct is accepted by the CLI but is never used or forwarded to the
server/index loading logic, creating a misleading CLI contract. Remove the
git_ref field definition (including the #[arg(long = "ref")] attribute) from the
argument struct to eliminate the non-functional flag. Verify that no other code
paths reference this field, particularly in the server/index loading section
around line 409 onward, to ensure no compilation errors occur after removal.- Around line 232-239: The code converts line_num from i64 to u32 without
validating that line_num does not exceed u32::MAX, which allows invalid inputs
to silently truncate and cause incorrect chunk lookup. After parsing the line as
i64 and before calling resolve_chunk, add validation to check if line_num
exceeds u32::MAX and return an appropriate error message if it does (similar to
the existing validation for negative numbers). Only proceed with the u32
conversion when line_num is within the valid range.In
@crates/csp/src/chunking/core.rs:
- Around line 49-62: The fit check in the chunk merging logic uses the sum of
individual segment lengths (current_length + length) rather than the actual span
that would result from merging boundaries. This ignores gaps between current_end
and group.start, which can cause the merged chunk's real span to exceed
desired_length. Replace the fit check condition to calculate the actual span
from current_start to group.end instead of summing the individual lengths, so
that the desired_length constraint accounts for all gaps within the merged
range.- Around line 110-118: The threshold check in the while loop of merge_node_inner
does not account for spacing between sibling nodes when determining if adding
the next child would exceed the desired length. Calculate the gap between the
current end position and the next child's start_byte, then include this gap in
the length calculation when evaluating whether run_length plus child_length plus
the gap exceeds desired_length. This ensures that the span size check accurately
reflects the total byte range needed including all inter-sibling spacing.In
@crates/csp/src/mcp.rs:
- Around line 199-203: The code checks if line is negative before converting to
u32, but lacks an upper-bound check for values exceeding u32::MAX. Add an
additional condition in the if statement to ensure line does not exceed u32::MAX
before calling the conversion in resolve_chunk. If line exceeds u32::MAX, it
should return None, similar to the existing negative check.In
@crates/csp/src/search.rs:
- Around line 72-74: The SelectableBasicBackend::query call uses .expect() which
causes a panic on backend errors instead of allowing graceful error handling
during search operations. Remove the .expect() call and instead return the
Result type directly so that callers can handle query failures appropriately
rather than crashing the process. This allows the search function to propagate
errors up the call stack where they can be handled more gracefully, particularly
important for MCP server usage where process crashes are undesirable.- Around line 90-91: Replace all instances of
sort_bywith
partial_cmp(...).expect(...)pattern with a NaN-safe ordering implementation
that gracefully handles NaN values without panicking. The current approach
assumes all scores are finite and will crash if NaN is encountered. Implement a
custom comparator (or use a built-in NaN-safe method) that defines a consistent
ordering for NaN values, such as placing them at the end or beginning of the
sorted sequence. Apply this fix to all occurrences mentioned in the comment: the
main instance around theranked.sort_bycall and also at the other locations
noted in the diff (lines 101-102, 177-178, 206-207, 277-278).In
@crates/csp/src/types.rs:
- Around line 133-137: The chunk_from_dict function does not validate line-range
invariants during deserialization of untrusted chunk data. After extracting
start_line and end_line from the dictionary, add validation checks to ensure
that start_line is at least 1 (not 0) and that end_line is greater than or equal
to start_line. Return ChunkFromDictError with descriptive messages if either
validation fails. Apply the same validation pattern to any other deserialization
locations mentioned at lines 147-153 where line ranges are extracted.In
@npm/csp/bin/csp.js:
- Around line 14-94: The code is violating the ESLint rule
node/prefer-global/process by using the global process object directly without
an explicit import. To fix this, add an explicit import statement for the
process module at the top of the file before the resolvePlatformPackage
function. This will allow all the existing usages throughout the file
(process.platform, process.arch, process.report, process.stderr, process.argv,
and process.exit) to reference the explicitly imported process binding instead
of relying on it being a global.- Around line 20-38: The code has brace-style formatting inconsistencies in the
platform detection logic. Ensure that allelse ifstatements are properly
formatted according to the project's brace-style rule by placing theelse
keyword on the same line as the closing brace of the preceding block, rather
than on a separate line. Review the conditional blocks for darwin, linux, and
their nested architecture checks, and adjust the brace positioning to maintain
consistent formatting throughout the function.In
@npm/csp/package.json:
- Around line 2-41: The package.json file fails the jsonc/sort-keys linting rule
because the keys are not in alphabetical order. Reorder all top-level keys in
the package.json (name, version, description, homepage, repository, bugs,
license, keywords, bin, files, engines, optionalDependencies) alphabetically.
Additionally, ensure the optionalDependencies object entries (the
@pleaseai/csp-* packages) are also sorted alphabetically by their key names.
This will satisfy the linting rule and pass CI checks.In
@npm/scripts/generate-platform-packages.mjs:
- Around line 31-93: The script uses the global process object (in process.argv,
process.stderr, process.exit, process.stdout) without explicitly importing it,
which violates the ESLint node/prefer-global/process rule. Add an explicit
import statement at the top of the generate-platform-packages.mjs file to import
process from the node:process module, then the linter will recognize the process
object as properly defined.In
@rust-toolchain.toml:
- Line 3: The components array assignment in rust-toolchain.toml does not follow
the enforced TOML array formatting style. Reformat the components array to use
multi-line formatting with proper newline and bracket spacing as required by the
TOML linter. This typically involves moving array elements to separate lines
with proper indentation while maintaining the opening bracket on the same line
as the assignment.
Minor comments:
In @.github/workflows/release-rust.yml:
- Around line 62-64: The checkout step using
actions/checkout@34e1148 is persisting
credentials unnecessarily since no git operations occur after checkout. Add the
parameter persist-credentials: false to the checkout action to reduce credential
exposure and improve security by preventing the GitHub token from being written
to the git config.In
@crates/csp/Cargo.toml:
- Around line 1-20: The Cargo.toml manifest has TOML lint violations related to
formatting rules for padding, array spacing, and newlines that are blocking CI.
Review the dependencies section and the overall manifest formatting to ensure
proper spacing around brackets, consistent padding in arrays, and correct
newline placement according to TOML lint standards. Use an auto-formatter or
manually adjust the whitespace to normalize the TOML style and pass the linter
validation.In
@crates/csp/src/mcp.rs:
- Around line 148-149: The source resolution logic on line 148 has incorrect
fallback behavior because repo.or(default_source).filter() applies the filter
after the or() operator, meaning an empty string in repo will prevent
default_source from being used. Fix this by filtering out empty strings from
repo before the or() operator so that an empty repo properly falls back to
default_source, then apply a final filter to check the result is not empty. This
ensures empty repo values are treated as missing and default_source can be used
as a valid fallback.In
@crates/csp/src/ranking/boosting.rs:
- Around line 229-233: The code in the loop at line 229-233 returns on the first
separator type that matches in the iteration order, rather than finding the
rightmost separator across all types. For mixed namespace styles likeA::B.C,
it matches::first and returnsB.C, but should instead find.which
appears rightmost and returnC. Refactor this logic to find the rightmost
position across all separators by checking all of them and comparing their
positions, then return the substring after whichever separator appears latest in
the query string.In
@crates/csp/src/ranking/penalties.rs:
- Around line 80-85: The basename extraction in the file path handling uses only
the forward slash character to split the path, which fails to properly extract
the basename from Windows-style paths containing backslashes. Modify the rfind
call in the basename extraction logic to handle both forward slashes and
backslashes as path separators. You can do this by replacing the single
character search with a closure that matches either '/' or '' character to
ensure consistent behavior across different path formats when checking against
REEXPORT_FILENAMES.In
@crates/csp/src/search.rs:
- Line 230: The candidate_count variable assignment uses regular multiplication
which can overflow when top_k is a large value. Replace the multiplication
operator with the saturating_mul method to ensure overflow-safe behavior. Change
the expression fromtop_k * 5totop_k.saturating_mul(5)to keep the
calculation deterministic and safe.

Replace the chunking stub (chunk() returned None, is_supported_language() returned false) with real tree-sitter parsing, based on the semble Python source (chunking/core.py): - Statically link a curated grammar set (rust, python, javascript, typescript, tsx, go, java, c, cpp, ruby, json, bash, html, css) — all compatible with tree-sitter 0.26 via the LanguageFn → Language conversion. Static linking keeps the single-binary goal (ADR-0003); the dynamic tree-sitter-language-pack was rejected for that reason. - language_for(name) maps semble language names to grammars; is_supported_language consults it. Unsupported languages still fall back to line chunking (semble behavior when no parser is available). - TsNode bridges tree_sitter::Node to the existing generic AstNode merge algorithm (children collected via a transient cursor). chunk() parses, runs merge_node on byte offsets, then converts boundaries to char offsets (semble's len(as_bytes[:n].decode())). Tests: replaced the stub-era assertions (typescript/python now supported) and added real-parse tests (rust splits into covering boundaries; multibyte byte→char conversion stays in range). 257 lib + 8 CLI tests pass; fmt/clippy green. Note: DESIRED_CHUNK_LENGTH_CHARS stays 1500 (current behavior); semble@main uses 750 — flagged separately, not changed here. Refs #33
Replace the deterministic embedding stub with the real Model2Vec model via
model2vec-rs (official MinishLab Rust port), based on semble's index/dense.py
(StaticModel.from_pretrained + encode):
- Model is now an enum: Static { Arc<StaticModel>, dim } (real) or Stub { dim }
(deterministic fallback). load_model loads the real model
(StaticModel::from_pretrained, HF id or local dir; dim probed via encode_single),
caching it; on any load error it falls back to the stub WITH a stderr warning so
indexing still degrades gracefully offline.
- The former TS stub (fnv1a/mulberry32/Box-Muller) is kept bit-for-bit as Model::Stub
for offline unit tests and the fallback path; its golden test still passes.
- load_model_with(loader) seam keeps unit tests fully offline; a #[ignore]d
network test exercises the real potion-code-16M download + encode.
- SelectableBasicBackend (cosine) unchanged. index.rs uses model.dim().
Verified: the network test loads potion-code-16M and embeds distinct vectors;
end-to-end "csp search" over a temp repo ranks the semantically-relevant chunk
first using real embeddings (no stub-fallback warning), with tree-sitter chunking
active for rust/python. 258 lib + 8 CLI tests pass (1 ignored network);

Tip: Review your code locally with the cubic CLI to iterate faster.
Re-trigger cubic
Robustness / correctness: - dense.rs, search.rs: NaN-safe ordering — replace partial_cmp().expect() sorts with total_cmp (a stray NaN can no longer panic the search path). - search.rs: vector backend query error degrades to no semantic hits + a stderr warning instead of panicking the long-running MCP server. - create.rs: lossy UTF-8 decode (read + from_utf8_lossy) to match the TS oracle's readFileSync(path,'utf8') — previously non-UTF-8 files were dropped. - cache.rs: ensure_cache_dir now propagates create/permission IO errors (Result<(),String>) so the 0700 cache guarantee can't fail silently. - main.rs: `clear index`/`clear all` returns a non-zero exit on failure. - main.rs find_related + mcp.rs find_related_tool: guard the full u32 range before `as u32` (a line above u32::MAX would wrap to the wrong chunk). - main.rs: wire `mcp --ref` through run_mcp → CspMcpServer → get_index so the default git source is pinned to the requested revision (was accepted/ignored). - main.rs: derive Debug on ContentFilter/Agent enums (Rust C-derive). CI / packaging: - rust.yml: persist-credentials: false on checkout; `cargo test --locked`. - release-rust.yml: macos-13 (retired Dec 2025) → macos-15-intel; validate the workflow_dispatch tag via env var before `gh release upload` (injection guard). - npm/csp/package.json: engines.node >=18 → >=22 (matches the project minimum). Docs: - plan.md: fix a stray Cyrillic "невалид" → "invalid". Refs #33

In `@eslint.config.ts`:
- Around line 20-22: In the eslint.config.ts file, the `npm` directory is being
entirely excluded from linting coverage, which prevents handwritten wrapper and
runtime JS/MJS files from being linted. Instead of excluding the entire `npm`
directory, replace this broad exclusion with more specific patterns that target
only generated files within that directory (such as paths like `npm/dist/` or
`npm/generated/`). This will maintain linting coverage for handwritten
JavaScript files while still allowing generated files to be excluded as needed.

CodeRabbit flagged that ignoring the whole npm/ tree dropped the maintained
launcher + generator from eslint coverage (the repo guideline requires all
**/*.{ts,tsx,js,jsx} to follow eslint rules). Narrow the ignore to the generated
npm/dist output and fix the now-surfaced lint in the hand-written files:
- eslint.config.ts: ignore `npm/dist` only (was `npm`).
- csp.js: import `process` via require('node:process'); brace-style → stroustrup.
- generate-platform-packages.mjs: `import process from 'node:process'`.
- npm/csp/package.json: jsonc/sort-keys ordering (license, optionalDependencies).
.codacy.yaml keeps excluding npm/** — Codacy's security heuristics (dynamic fs
paths, spawn-with-variable) misfire on a distribution launcher/generator; that
exclusion is on different grounds than the eslint coverage contract.

Rust rewrite of

crates/csplibrary +crates/csp-clicspbinary), verified against the TS test suite reused as golden fixtures. Closes the bulk of trackrust-rewrite-20260618(T001–T024).Status — 263 tests green (255 lib + 8 CLI), fmt + clippy

dense.ts) and the inline search-ranking shims (search.tsTODO(integration)). The Rust port reproduces those stubs bit-for-bit.
