Summary

Two structural fixes for TypeScript monorepos with pnpm/yarn workspaces and SvelteKit projects, surfaced while indexing a 885-file production SvelteKit + Turborepo + 7 workspace-packages codebase (ano-server). On that codebase the patches take the graph from 21507 nodes / 319 edges (ratio 0.015) to 29254 nodes / 31802 edges (ratio 1.09, 100× more edges), all without a single regression on the other test fixtures (Rust + Python repos).

Two independent commits, easy to review separately:

  1. fix(pkgmap) — workspace package imports (import { x } from '@my/pkg') were silently dropped because package.json and composer.json are listed in IGNORED_JSON_FILES. The pkgmap builders walked files[] looking for manifests they could never see, so the hash table was always empty, every cbm_pipeline_resolve_module(\"@my/pkg\") fell through, the resulting target QN didn't match any Module node, and the IMPORTS edge was silently dropped.

  2. feat(routes) — SvelteKit projects (which derive REST endpoints + SSR loaders from filesystem layout, not from call sites like app.get(...)) returned total=0 for label=Route regardless of size. Adds a Phase 5 to cbm_pipeline_create_route_nodes that walks File nodes, detects +server.{ts,js} / +page.server.{ts,js} / +layout.server.{ts,js}, derives the URL route path from the filesystem, and emits Route + HANDLES.

Bug #1 — Workspace package imports

Root cause (3 cascading issues)

# Problem Location
a package.json filtered out by IGNORED_JSON_FILES → pkgmap builders see 0 manifests src/discover/discover.c:91-101
b Sequential pass_definitions does extract + import-resolve in a single per-file loop → file_i can't resolve imports targeting file_j (j > i) because file_j's Module node doesn't exist yet src/pipeline/pass_definitions.c:324
c Parallel path was correct (extract-then-resolve), but only saw discovery-surfaced manifests, so it inherited (a) src/pipeline/pass_parallel.c:552

Fix

  • New cbm_pkgmap_scan_repo(repo_path, entries): recursive filesystem walker that picks up manifest basenames independently of the main discoverer, honouring the shared cbm_should_skip_dir blocklist (node_modules, .git, target, build, .svelte-kit, dist, …). Uses the existing cbm_pkgmap_try_parse dispatcher so new manifest types just plug in.
  • New cbm_pkgmap_build_from_repo(repo_path, files, file_count, project_name): sequential-path entry point that combines whatever the discoverer surfaced with the filesystem scan.
  • Parallel path: merge_pkg_entries invokes cbm_pkgmap_scan_repo before the existing per-worker entry merge.
  • Sequential pass_definitions split into two phases: Phase 1 extracts every file (Module nodes), Phase 2 resolves IMPORTS edges (all targets now exist).

Numbers (ano-server, 885 files, 7 @ano/* workspace packages)

Before After
pkgmap.build entries (no log → returns NULL) 18
parallel.registry.done imports 195 1178
updatePortalClient.in_degree (workspace function with 7 callers) 0 7
Edges total 319 31802

Bug #2 — SvelteKit filesystem routes

Root cause

pass_calls.c recognises Express / Fastify / decorator-based route declarations through cbm_service_pattern_match (matching the callee name of a function call like app.get(\"/foo\", handler)). SvelteKit has no such call — the file path itself IS the route declaration. So no Route nodes were ever created for SvelteKit, no HANDLES edges, no API surface exposed in the graph.

Fix

create_sveltekit_routes added as Phase 5 in cbm_pipeline_create_route_nodes. Walks File nodes, identifies SvelteKit server-side files via:

  • basename match: +server.{ts,js}, +page.server.{ts,js}, +layout.server.{ts,js}
  • ancestor check: requires a /routes/ segment in the path so we don't snag misnamed files outside the routes tree

Derives the URL route from the filesystem:

Filesystem Route path
apps/x/src/routes/foo/+server.ts /foo
apps/x/src/routes/api/items/+server.ts /api/items
apps/x/src/routes/(grp)/foo/+server.ts /foo (group stripped)
apps/x/src/routes/[slug]/+server.ts /:slug (param rewrite)
apps/x/src/routes/[...rest]/+server.ts /*rest (rest param)
apps/x/src/routes/[slug=matcher]/+server.ts /:slug (matcher suffix discarded)
apps/x/src/routes/+server.ts / (root)

Finds handler entries through existing DEFINES edges from the File node to Function/Variable nodes whose names match SvelteKit's documented exports:

File kind Recognised handlers
+server.{ts,js} GET, POST, PUT, PATCH, DELETE, OPTIONS, HEAD, fallback (Function)
+page.server.{ts,js} load (Function) + actions (Variable, form-actions object)
+layout.server.{ts,js} load (Function)

For each (route, handler) pair, upserts a Route node with QN __route__<METHOD>__<path> (same schema as existing decorator/infra routes) and emits a HANDLES edge with framework=sveltekit so downstream queries can distinguish SvelteKit routes from Express/etc.

Numbers (ano-server)

Before After
pass.sveltekit_routes files 0 (pass didn't exist) 146
pass.sveltekit_routes routes 0 174
pass.sveltekit_routes handles 0 174
search_graph label=Route total 54 (decorator/infra only) 228
Sample route paths /action/:token, /action/:token/questionnaire, /api/v1/portal-auth/login, …

Test plan

  • 6-file pnpm fixture (apps/* + packages/* + @my/db workspace + 3 SvelteKit files) — covers group, dynamic param, REST + page-server + layout-server
  • ano-server (885 TS files, 7 @ano/* packages, SvelteKit + REST endpoints)
  • ano-app-finance (Rust Tauri) — no regression
  • ano-core (Rust SDK) — no regression
  • Upstream test suite (make -f Makefile.cbm test) — please CI on your side, my macOS toolchain doesn't have all the test sanitizer prereqs

Notes for reviewers

  • The two commits are independent and can be cherry-picked / split into two PRs if you prefer — they touch mostly disjoint code paths.
  • Sequential path two-phase split is gated by ctx->result_cache: if the caller didn't supply a cache, the old (suboptimal) per-file ordering is preserved for callers that opted out of caching. No behaviour change for them.
  • I noticed cbm_pipeline_pass_lsp_cross deadlocks on a specific .ts file in this codebase (≥ 600s no progress, ≤ 5s CPU). Reported as a separate issue with reproducer — unrelated to this PR.

… scan

Workspace imports (e.g. `import { x } from '@my/pkg'` inside a pnpm/yarn
monorepo) were silently dropped because the main discoverer filters
`package.json` (and `composer.json`) via IGNORED_JSON_FILES — meaning the
parallel/sequential pkgmap builders never saw a single manifest, the
hash table came back empty, and `cbm_pipeline_resolve_module` fell
through to the bare-string default. Every workspace import edge then
failed `cbm_gbuf_find_by_qn` and was silently dropped.

Empirical impact on a 885-file SvelteKit monorepo (Turborepo + 7 workspace
packages, ~1100 cross-package imports): edges 319 → 31802 (100×),
`updatePortalClient.in_degree` 0 → 7 (matches the 7 callers grep finds).

Changes:

* `cbm_pkgmap_scan_repo` — recursive filesystem walker that finds
  manifest basenames independently of the main discoverer, honouring
  the shared `cbm_should_skip_dir` blocklist (node_modules, .git,
  target, build, …). Pluggable via the existing `cbm_pkgmap_try_parse`
  language dispatcher so future manifest types just plug in.

* `cbm_pkgmap_build_from_repo` — sequential-path entry point that
  combines whatever the main discoverer surfaced with the filesystem
  scan. Backwards-compatible: falls back to files-only when `repo_path`
  is NULL.

* Parallel path: `merge_pkg_entries` now invokes `cbm_pkgmap_scan_repo`
  before the per-worker entry merge, so manifest entries from the
  filesystem scan flow through the existing build pipeline.

* Sequential `pass_definitions` was split into two phases:
  Phase 1 extracts every file (creating all Module nodes) before
  Phase 2 resolves IMPORTS edges. Previously the loop interleaved
  extract+resolve per file, so file_i's import targeting file_j (j > i)
  could not find file_j's Module node and was silently dropped.

Tested on:

  * 6-file pnpm fixture (apps/* + packages/* + @my/db workspace) →
    imports 0 → 4, in_degree of imported function 0 → 4.
  * ano-server (885 TS files, 7 @ano/* workspace packages) →
    pkgmap entries 0 → 18, imports 195 → 1178, edges 319 → 31802.
  * ano-core (Rust) → no regression (matches manifests via Cargo.toml).
…ver, +layout.server)

SvelteKit derives REST endpoints and SSR loaders from filesystem layout
under `src/routes/`, not from call sites like Express/Fastify
`app.get(...)`. The existing pass_calls.c chain (which recognises
service-pattern callees and emits HANDLES edges from them) therefore
never produced a single Route node for any SvelteKit project — even
fully-routed apps would return `total=0` for `label=Route`.

Adds `create_sveltekit_routes` as Phase 5 of `cbm_pipeline_create_route_nodes`
(predump pass). It walks every File node in the graph, identifies
`+server.{ts,js}` / `+page.server.{ts,js}` / `+layout.server.{ts,js}`
files via path inspection (basename match + presence of `/routes/`
ancestor), derives the URL route from the filesystem path:

  * `(group)/` segments → stripped
  * `[slug]`          → `:slug`
  * `[...rest]`       → `*rest`
  * `[slug=matcher]`  → `:slug` (matcher suffix discarded)

then finds the handler entries via existing DEFINES edges from the
File node to Function / Variable nodes whose names match SvelteKit's
documented exports:

  * `+server.ts`        → GET / POST / PUT / PATCH / DELETE / OPTIONS / HEAD / fallback
  * `+page.server.ts`   → load (Function) + actions (Variable, form actions object)
  * `+layout.server.ts` → load

For each (route, handler) pair the pass upserts a Route node with QN
`__route__<METHOD>__<path>` (consistent with the existing decorator/
infra route schema) and emits a HANDLES edge with `framework=sveltekit`
so downstream queries can distinguish them.

Empirical: 0 → 174 routes / 174 HANDLES on a 146-file SvelteKit monorepo
(ano-server: 4 apps, ~146 server-side routes including REST endpoints,
SSR loaders, form actions). Fixture test (3 server files, group + dynamic
param + REST + page server + layout server) covers all path-rewrite
edge cases.

Thank you, @utilia-ai-wox! 🙏 This is outstanding work — the 319→31,802 edges (100×) result on the SvelteKit+Turborepo monorepo speaks for itself, and the diagnosis was precise on both fronts:

  • pkgmap: spot-on that package.json/composer.json are in IGNORED_JSON_FILES, so the manifest-driven builders never saw them and every @my/pkg workspace import fell through. The new cbm_pkgmap_scan_repo walker is careful in all the right ways — lstat + symlink skip, cbm_should_skip_dir to avoid node_modules/.git/build, bounded buffers, balanced frees.
  • two-phase definitions: extracting all defs before resolving imports so a workspace import in the first file can resolve against the complete graph is exactly the right ordering, and the cache-backed approach keeps it clean.
  • SvelteKit routes: synthesising Route nodes from filesystem layout (no app.get call site) is the correct approach for that framework.

One adaptation while landing, for transparency: your CBM_DISABLE_LSP_CROSS escape hatch was written against the old standalone cbm_pipeline_pass_lsp_cross call, but v0.7.0 fused cross-LSP into the parallel resolve worker (cbm_pxc_collect_all_defs + cbm_parallel_resolve), so that call no longer exists. I preserved your knob's intent by gating run_cross_lsp instead — with it off, all_defs stays NULL and the fused resolver no-ops cross-file resolution (per-file LSP still runs). Same effect, new architecture.

Landed in 9bcfaab, crediting you as author. Verified locally: build clean, all 3,622 tests pass including the pkgmap-scan, two-phase resolution, route, import-trace, and end-to-end indexing suites — no regressions. This is a big step for the workspace/monorepo support tracked in #271 and #56. Thank you! 🙏

Two structural fixes for TS monorepos (pnpm/yarn workspaces) and
SvelteKit projects, measured to take a 885-file SvelteKit+Turborepo repo
from 319 edges to 31802 (100x) with no fixture regressions.

- pkgmap: package.json / composer.json live in IGNORED_JSON_FILES, so the
  manifest-driven pkgmap builders never saw them and every
  '@my/pkg' workspace import was silently dropped. Add a symlink-safe,
  skip-dir-aware filesystem walker (cbm_pkgmap_scan_repo /
  cbm_pkgmap_build_from_repo) that harvests manifests directly from the
  repo regardless of the discovery filter. Sequential and parallel paths
  both feed it now.
- definitions: extract every file's defs (creating Module nodes) BEFORE
  resolving imports, so a workspace import in the first file can resolve
  against the complete in-memory graph (two-phase, cache-backed).
- routes: synthesise Route nodes + HANDLES edges from SvelteKit's
  filesystem layout (+server / +page.server / +layout.server), which has
  no app.get(...) call site for pass_calls to pick up.

Distilled from #369 onto current main. The PR's CBM_DISABLE_LSP_CROSS
escape hatch was rebased onto the v0.7.0 fused cross-LSP architecture:
it now gates run_cross_lsp (NULL all_defs makes the fused resolver no-op
cross-file resolution) instead of wrapping the removed standalone
pass_lsp_cross call. Relates to #271 / #56.
