fix: content-hash staleness detection for embeddings and vector index creation on zero-node path (#831)
* Initial plan

* fix: stale vectors preserved on content edits and vector index missing after zero-node run

Issue 1: Add contentHash to EMBEDDING_SCHEMA and embedding pipeline.
- contentHash column persisted per CodeEmbedding row
- POST /api/embed queries nodeId+contentHash, compares per-node hash
- Stale rows (hash mismatch) are DELETE'd before re-embedding
- Legacy DBs without contentHash treated as stale (full re-embed)
- loadCachedEmbeddings and run-analyze cache restore include contentHash

Issue 2: createVectorIndex called unconditionally before zero-node early return.

Regression tests:
- contentHashForNode determinism and content-change detection
- EMBEDDING_SCHEMA includes contentHash STRING column
- Pipeline exports verified

* fix: address review feedback — config consistency, narrow catches, extract DB logic

Bug #1: Use finalConfig consistently in contentHashForNode (line 224 was
using raw `config` while line 307 used `finalConfig`). Cache precomputed
hashes in filter phase to avoid double computation (Perf #5).

Bug #2: Narrow catch in loadCachedEmbeddings to only fall back on
column/table-missing errors. Rethrow transient/connection errors.

Bug #3: Log non-trivial DELETE failures instead of silently swallowing.

Arch Violation #3: Extract fetchExistingEmbeddingHashes from api.ts into
lbug-adapter.ts. Server layer now calls a single adapter function instead
of re-implementing the DB query logic with nested try-catch.

Tests: Add config consistency test, note that fetchExistingEmbeddingHashes
tests require native module (run in CI).

* fix: narrow Column error match to 'contentHash' in lbug-adapter fallback checks

* fix: address production-readiness review — eliminate competing state, use schema constants, hard-fail on stale DELETE, add incremental filter tests

Gap A / Arch Violation 1: Remove duplicate vectorExtensionLoaded flag from
embedding-pipeline.ts — delegate to lbug-adapter's loadVectorExtension()
which owns the VECTOR extension lifecycle and resets on DB reconnect.

Arch Violation 2: Replace all hardcoded 'CodeEmbedding' and
'code_embedding_idx' strings in embedding-pipeline.ts and run-analyze.ts
with EMBEDDING_TABLE_NAME, EMBEDDING_INDEX_NAME, and CREATE_VECTOR_INDEX_QUERY
imported from schema.ts. Add EMBEDDING_INDEX_NAME export to schema.ts.

Gap B: Make DELETE failure for stale vectors a hard throw (not just a
warning). Continuing after failed DELETE risks Kuzu vector-index corruption
since the constraint requires DELETE-before-INSERT for vector-indexed
properties. "not found" / "does not exist" errors are still safe to ignore.

STALE_HASH_SENTINEL: Define a named constant in embedding types.ts for the
empty-string sentinel convention. Used consistently in lbug-adapter.ts and
run-analyze.ts so the invariant is self-documenting.

Tests: Add comprehensive unit tests for the incremental filter logic with
mocked embedder:
- New node → embedded
- Unchanged node (hash matches) → skipped
- Stale node (hash mismatch) → DELETE + re-embed
- STALE_HASH_SENTINEL → treated as stale
- Zero nodes after filter → createVectorIndex still called
- DELETE failure with non-trivial error → throws

* fix: tighten error classification — extract isMissingColumnOrTableError helper, remove broad pattern matching

- Extract isMissingColumnOrTableError() helper in lbug-adapter for
  consistent schema-error detection (replaces duplicate inline checks)
- Tighten 'contentHash' match: now requires 'property' AND 'contentHash'
  (Kuzu-specific pattern) instead of broad 'contentHash' substring
- Tighten DELETE error check: only ignore 'does not exist' (Kuzu's actual
  message), not broad 'not found' which could mask connection errors
- Fix test node ID/name/filePath consistency

* fix: CI failures and final review — move STALE_HASH_SENTINEL to schema, tighten error matching, fix test mocking, format

- Move STALE_HASH_SENTINEL from embeddings/types.ts to lbug/schema.ts
  (fixes inverted layer dependency: lbug should not import from embeddings)
- Tighten isMissingColumnOrTableError: replace broad msg.includes('not found')
  with /(table|column|property).*not found/i regex to avoid matching transient errors
- Add vi.resetModules() in test beforeEach for explicit module isolation
  (fixes vi.doMock not intercepting loadVectorExtension in CI)
- Skip precomputedHashes.set() on unchanged (return false) path
- Run prettier on all 5 files flagged by CI format check

Agent-Logs-Url: https://github.com/abhigyanpatwari/GitNexus/sessions/e20311fd-4361-47b4-a137-9adc3e533b35

* fix: address remaining review nits — rename precomputedHashes, generalize error matcher, revert package-lock

- Rename precomputedHashes → computedStaleHashes (hashes are computed
  on-demand during filter, only cached for stale nodes being re-embedded)
- Remove contentHash-specific clause from isMissingColumnOrTableError —
  the regex /(table|column|property).*not found/i already covers it
- Revert package-lock.json ssh→https protocol change

fix(embeddings): prevent batch errors from CodeEmbedding PK violations and vector-index SET restriction (#823)
* fix(csv-generator): deduplicate all node types, not just File nodes

The pipeline can produce duplicate node IDs across all symbol types
(Class, Method, Function, etc.). Only File nodes were guarded by a
seenFileIds Set, leaving every other type unprotected. When the CSV
was COPY'd into LadybugDB, duplicate PKs caused mass "Batch execution
error: Found duplicated primary key value" warnings on gitnexus serve.

Replace the per-type seenFileIds with a single seenNodeIds Set checked
at the top of the iteration loop, before the switch, so every label is
covered by the same O(1) deduplication guard.

Fixes: #822

* fix(embeddings): use MERGE instead of CREATE for CodeEmbedding inserts

CREATE fails with duplicate PK when a CodeEmbedding node already exists,
which happens when:
- A PostToolUse hook triggers a concurrent gitnexus analyze during an
  active analyze run (git commits fire the hook)
- A partial prior run left some embeddings in the DB before a crash

Switching to MERGE makes the insert idempotent: existing embeddings are
updated in place, new ones are created, no PK violations.

Fixes: #822

* fix(server): skip already-embedded nodes in POST /api/embed to avoid vector-index SET error

Kuzu/LadybugDB forbids SET on a property that is part of a vector index.
The /api/embed endpoint was calling runEmbeddingPipeline without skipNodeIds,
causing it to attempt MERGE+SET on every node including those already embedded.

Fix: query existing CodeEmbedding nodeIds before running the pipeline and pass
them as skipNodeIds so only new (unembedded) nodes are processed.

* fix(server): narrow catch to table-not-exist errors only in POST /api/embed

Bare catch{} would silently swallow connection errors and proceed to
re-embed all nodes, hiding infrastructure issues. Now only swallows
errors where the CodeEmbedding table does not yet exist.

* style: prettier format gitnexus/src/server/api.ts

* fix(server): log skip-embedding count and table-not-found swallow path

Addresses review feedback on PR #823:
- Log count of already-embedded nodes when skipNodeIds is populated
  (aids debugging if Kuzu driver row shape changes).
- Log when the 'table does not exist' swallow path fires so ops can
  catch it if Kuzu ever changes error wording.
- Document the {} config positional argument with an inline comment
  referencing the runEmbeddingPipeline signature.

52277247fe feat(group): add group infrastructure and contract matching
Core foundation for repository group analysis:
- Type system: ContractType, ExtractedContract, StoredContract, CrossLink
  with optional `service` field for intra-repo matching
- Config parser for group.yaml (repos, detection flags, matching thresholds)
- Contract registry storage with atomic writes
- Exact matching engine with per-type normalization (HTTP, gRPC, topic)
  and intra-repo support (different services within same repo can match)
- Extract LadybugDB pool-adapter from MCP backend for reuse by sync pipeline
- Git staleness checker for group status reporting

feat: configure prettier with pre-commit hook (#563)
* feat: configure prettier with pre-commit hook integration

Add prettier, lint-staged, and prettier-plugin-tailwindcss at the repo
root with husky pre-commit hook integration. Moves husky from
gitnexus/ to root package.json for reliable hook installation.

- Root package.json with prepare/format/format:check scripts
- .prettierrc with endOfLine:lf and tailwindStylesheet for TW v4
- .prettierignore excluding fixtures, vendor, generated, *.d.ts, *.md
- .gitattributes enforcing LF line endings for Windows consistency
- Pre-commit hook uses direct node_modules/.bin/ paths (no npx)

* style: apply prettier formatting to entire codebase

One-time bulk format. No logic changes.
Use .git-blame-ignore-revs to skip this commit in git blame.

* chore: add .git-blame-ignore-revs for prettier format commit

* perf: pre-commit hook runs only tests related to staged files

Use vitest --related to scope test execution to tests that import
the changed files, instead of running the full suite on every commit.

* perf: remove vitest from pre-commit hook, keep in CI only

Pre-commit now runs lint-staged + tsc only. Tests run in CI
(ci-tests.yml) where they belong — keeps commits fast.

* ci: add prettier format check to quality workflow

PRs will now fail if code isn't formatted with prettier.

feat: unify web and cli ingestion pipeline (#536)
* feat: add server-side ingestion API (POST /api/analyze, SSE progress)

Extract core analysis orchestration from CLI into shared run-analyze.ts
module. Add server-side analyze endpoints so the web app can trigger
ingestion via HTTP instead of running the full pipeline in-browser.

New files:
- src/core/run-analyze.ts — shared runFullAnalysis() orchestrator
- src/server/analyze-job.ts — job manager (single-slot, dedup, SSE events)
- src/server/analyze-worker.ts — forked child process (8GB heap, IPC)
- src/server/git-clone.ts — shallow clone/pull with SSRF protection

API endpoints:
- POST /api/analyze — start analysis (returns 202 + jobId)
- GET /api/analyze/:jobId — poll job status
- GET /api/analyze/:jobId/progress — SSE progress stream

Security: URL validation blocks private IPs and non-HTTP schemes.
Path validation requires absolute paths. Git stderr not leaked to API.

* feat(web): add server-side analyze UI (Phase 2)

Add "Analyze on Server" flow to the web app's Server tab so users
can trigger server-side ingestion from the browser. On completion,
the graph is automatically loaded via the existing connectToServer flow.

New files:
- AnalyzeProgress.tsx — progress bar with phase label, elapsed time, cancel

Modified files:
- backend.ts — startAnalyze(), streamAnalyzeProgress() SSE client
- DropZone.tsx — analyze URL input + button below Connect section
- App.tsx — onServerAnalyze handler wires analyze -> connect flow

* feat: add job cancellation, timeout, and child process tracking (Phase 3)

- DELETE /api/analyze/:jobId — cancel running analysis (SIGTERM to worker)
- 30-minute timeout kills long-running workers automatically
- Child process refs tracked in JobManager for cleanup on shutdown
- dispose() kills all active children on SIGINT/SIGTERM
- Web cancel button now calls server DELETE endpoint
- cancelAnalyze() added to web backend client

* refactor(web): remove browser ingestion pipeline (Phase 4)

Delete 16 duplicated ingestion files, 2 unused service files
(git-clone, zip), and tree-sitter parser-loader from gitnexus-web.
All ingestion now runs server-side via POST /api/analyze.

Deleted (18 files, ~5,000 lines):
- core/ingestion/*.ts (16 pipeline processors)
- core/tree-sitter/parser-loader.ts (WASM tree-sitter loader)
- services/git-clone.ts (isomorphic-git client-side clone)
- services/zip.ts (JSZip extraction)

Simplified:
- DropZone.tsx — server-only (removed ZIP/GitHub tabs)
- ingestion.worker.ts — removed runPipeline/runPipelineFromFiles
- useAppState.tsx — removed pipeline callbacks
- App.tsx — removed handleFileSelect/handleGitClone
- main.tsx — removed Buffer polyfill for isomorphic-git
- types/pipeline.ts — removed PipelineResult/serialize helpers

Kept: cluster-enricher.ts (LLM enrichment, still used by worker)

Dependencies now removable: web-tree-sitter, isomorphic-git,
@isomorphic-git/lightning-fs, jszip (estimated 3-4MB bundle savings)

* refactor(web): sync graph schema from CLI + delete WASM grammars

Sync graph/types.ts and lbug/schema.ts from the CLI (source of truth)
to the web module so the browser LadybugDB can handle all node and
relationship types the server pipeline produces.

Synced types: Route, Tool, Section node labels; HANDLES_ROUTE, FETCHES,
HANDLES_TOOL, ENTRY_POINT_OF, WRAPS, QUERIES relationship types;
description fields on Function/Class/Interface/Method/CodeElement.

Deleted: public/wasm/ directory (14 tree-sitter WASM grammars + core).
Removed deps: web-tree-sitter, isomorphic-git, @isomorphic-git/lightning-fs,
jszip, buffer, @types/jszip (~3-4MB bundle savings).

* feat: create gitnexus-shared package for unified type definitions

Create a new gitnexus-shared package that is the single source of truth
for types shared between the CLI and web modules:

- SupportedLanguages enum (15 languages)
- Graph types: NodeLabel, NodeProperties, RelationshipType, GraphNode, GraphRelationship
- Schema constants: NODE_TABLES, REL_TYPES, REL_TABLE_NAME, EMBEDDING_TABLE_NAME
- Pipeline types: PipelinePhase, PipelineProgress

Both gitnexus (CLI) and gitnexus-web import from gitnexus-shared via
file: dependency. Each package re-exports and extends with platform-specific
additions (CLI: KnowledgeGraph with mutation methods; Web: simpler KnowledgeGraph).

This ensures types can never drift between packages — adding a new
language, node type, or relationship type in gitnexus-shared automatically
propagates to both consumers.

* refactor: import shared types directly from gitnexus-shared at call sites

Replace all re-export patterns with direct imports from gitnexus-shared.
72 files updated across CLI and web:

- SupportedLanguages: 49 CLI files now import from 'gitnexus-shared'
  instead of '../config/supported-languages.js'
- GraphNode, GraphRelationship, NodeLabel: 22 CLI + 10 web files now
  import from 'gitnexus-shared' instead of local re-export wrappers
- NODE_TABLES: api.ts imports from 'gitnexus-shared'
- PipelineProgress: useAppState.tsx imports from 'gitnexus-shared'

Local types.ts files now only define platform-specific KnowledgeGraph
(CLI has mutation methods, web has add-only). No more re-exports.

* fix: update lock files for gitnexus-shared, remove stale vite polyfills

Add gitnexus-shared@1.0.0 to lock files so npm ci succeeds in CI.
Remove buffer polyfill and global define from vite.config.ts (isomorphic-git was removed).

* fix(security): add write guard to HTTP /api/query, fix CORS proxy bypass

- Add isWriteQuery() check to POST /api/query handler — blocks CREATE,
  DELETE, SET, MERGE, DROP, etc. via HTTP API (guard was only in MCP
  pool adapter and browser-side, not the HTTP server path)
- Extend CYPHER_WRITE_RE with CALL, INSTALL, LOAD keywords
- Fix CORS proxy subdomain bypass: endsWith('github.com') allowed
  'evil-github.com'. Now requires exact match or '.github.com' suffix

* feat(server): enhance /api/search with enrichment, add /api/grep, strip graph content

- POST /api/search: add mode param (hybrid|semantic|bm25), server-side
  enrichment returns connections/cluster/processes per result in one call
  (collapses 31 sequential HTTP calls to 1 for the agent search tool)
- GET /api/grep: regex search across indexed file contents, eliminates
  need to transfer all file contents to browser
- GET /api/graph: strip content field by default (80-95% payload
  reduction). Use ?includeContent=true for backward compat
- Add LRU cache invalidation hook point for future caching

* feat(server): add /api/embed endpoint for server-side embedding generation

- POST /api/embed: triggers embedding pipeline via onnxruntime-node
  with JobManager for single-slot concurrency, timeout, and dedup
- GET /api/embed/:jobId: poll job status
- GET /api/embed/:jobId/progress: SSE stream with heartbeat, event IDs,
  and X-Accel-Buffering:no header for proxy compatibility
- DELETE /api/embed/:jobId: cancel running embedding job
- Maps embedding pipeline phases (ready→complete, error→failed) to
  JobManager status conventions

* feat(web): create consolidated BackendClient module

Single HTTP client replacing backend.ts, server-connection.ts, and
worker HTTP helpers. Includes:
- Typed methods: runQuery, search (enriched), grep, readFile, connect
- Generic streamSSE<T> utility extracted from analyze progress pattern
- BackendError with discriminated code field (network/server/client/timeout)
- Embed API: startEmbeddings, streamEmbeddingProgress, cancelEmbeddings
- Search with mode param (hybrid|semantic|bm25) and enrichment

* refactor(web): rewrite Graph RAG tools for backend-only HTTP queries

- Search tool: uses enriched /api/search (1 call replaces 31 sequential queries)
- Cypher tool: removes browser-side embedding; {{QUERY_VECTOR}} routes to
  /api/search with mode:'semantic' instead of local transformers.js
- Grep tool: uses /api/grep instead of in-memory fileContents map
- Read tool: uses /api/file instead of fileContents map lookup
- Impact tool: getCallSiteSnippet now async via /api/file
- createGraphRAGTools now accepts GraphRAGBackend interface instead of
  7 separate function params + fileContents map
- createGraphRAGAgent simplified to (config, backend, context?)
- Removed imports: embedder, lbug/schema (replaced with gitnexus-shared)
- Net: -205 lines

* refactor(web): delete WASM infrastructure, remove 7 packages (-5242 lines)

Delete browser-side LadybugDB, embeddings, search, and worker:
- gitnexus-web/src/core/lbug/ (adapter, csv-generator, schema, query-result)
- gitnexus-web/src/core/embeddings/ (embedder, pipeline, text-gen, types)
- gitnexus-web/src/core/search/ (bm25-index, hybrid-search)
- gitnexus-web/src/workers/ingestion.worker.ts (828 lines)
- gitnexus-web/src/services/server-connection.ts (merged into backend-client)
- gitnexus-web/src/types/lbug-wasm.d.ts

Remove packages: @ladybugdb/wasm-core, @huggingface/transformers,
comlink, minisearch, vite-plugin-wasm, vite-plugin-top-level-await,
vite-plugin-static-copy

Update vite.config.ts: remove WASM plugins, COOP/COEP headers,
worker config, optimizeDeps exclude

Update imports: App.tsx, DropZone, Header, AnalyzeProgress,
BackendRepoSelector, useBackend → backend-client

* refactor(web): replace Worker/Comlink with direct BackendClient calls

- useAppState: remove Worker instantiation, Comlink.wrap, apiRef.
  All queries now go through BackendClient HTTP functions directly.
- Agent runs on main thread (I/O-bound LLM streaming, not CPU-bound)
- initializeAgent: creates GraphRAGAgent with GraphRAGBackend interface
  bound to BackendClient methods (runQuery, search, grep, readFile)
- startEmbeddings: calls POST /api/embed + SSE progress instead of
  running browser-side transformers.js pipeline
- switchRepo: no longer loads graph into WASM DB or extracts fileContents
- App.tsx: handleServerConnect simplified (no fileContents, no loadServerGraph)
- Delete old backend.ts (replaced by backend-client.ts)
- Net: -396 lines

* fix(web): fix await-in-map build error in agent streaming

Move dynamic import of AIMessage outside .map() callback to avoid
"await can only be used inside an async function" build error.

* fix(web): remove stale apiRef references that broke chat functionality

sendChatMessage referenced apiRef.current (deleted Worker ref) which
would throw TypeError. Replaced with agentRef.current guard since agent
now runs on main thread.

* fix(server): dispose embedJobManager on shutdown, fix job mutation

- Add embedJobManager.dispose() to shutdown handler (was missing,
  causing cleanup timer to keep Node process alive)
- Replace direct job.repoName/status mutation with updateJob() to
  ensure SSE event emission for initial status change

* fix(server): parameterize Cypher, harden grep, unify SSE endpoints

- Search enrichment: replace string interpolation with executePrepared()
  using $nid parameter binding to prevent Cypher injection
- Add executePrepared() to core lbug-adapter (prepare/execute pattern)
- /api/grep: add 200-char pattern length limit (ReDoS protection),
  search files on disk instead of loading entire corpus into memory
  (constant memory usage regardless of repo size)
- Extract mountSSEProgress() shared helper for SSE streaming — both
  analyze and embed endpoints now have consistent heartbeat (30s),
  event IDs (reconnection support), and X-Accel-Buffering header

* refactor(web): remove dead code from Worker-era architecture

- Remove loadServerGraph no-op function, interface member, and all consumers
- Remove testArrayParams stub and interface member
- Remove fileContents state from GraphStateProvider (never populated in
  server-side architecture)
- Remove forceDevice parameter from startEmbeddings (server-side, no device choice)
- Replace phantom EmbeddingProgress type with inline { phase, percent }
- Replace resolvePathFromContents (needed fileContents Map) with graph-based
  file path resolution using filePathIndex built from graph nodes
- Fix: AI citation grounding ([[file.ts:10]]) now works via graph node lookup
  instead of broken fileContents-based resolution

* fix(web): use streamAgentResponse for full tool_call/reasoning streaming

Replace naive agent.stream() loop that only handled content chunks with
streamAgentResponse() generator from agent.ts. This properly routes:
- reasoning tokens (before/between tool calls)
- tool_call events (name, args, status)
- tool_result events (completed tool output)
- content tokens (final answer after all tools done)

Previously the onChunk handler for tool_call/tool_result/reasoning was
dead code since the streaming loop only emitted content events.

* fix(web): resolve CI type errors from dead code removal

- Import GraphNode/GraphRelationship from gitnexus-shared in graph.ts
  (not re-exported from local types.ts)
- Add Route, Tool entries to NODE_COLORS and NODE_SIZES constants
- Add PipelineResult type to web types/pipeline.ts
- Remove fileContents from CodeReferencesPanel and RightPanel
- Remove testArrayParams and forceDevice from EmbeddingStatus
- Remove forceDevice args from startEmbeddings() calls in App.tsx
- Fix embeddingProgress property accesses for simplified type

* fix(ci): add setup-gitnexus-web action, build shared once per job

- Remove prepare script from gitnexus-shared (tsc not available during
  npm ci of consuming packages)
- Create .github/actions/setup-gitnexus-web composite action: builds
  gitnexus-shared then runs npm ci for gitnexus-web
- setup-gitnexus action: already builds gitnexus-shared for CLI jobs
- ci-quality typecheck-web: uses setup-gitnexus-web (DRY)
- ci-e2e: uses setup-gitnexus-web (DRY)
- ci-tests: gitnexus-shared already built by setup-gitnexus, just
  install web deps without rebuilding

* fix(ci): use prepare script so gitnexus-shared builds during npm ci

Move typescript from devDependencies to dependencies in gitnexus-shared
so the prepare script (tsc) works when npm resolves file: deps during
npm ci. No GHA modifications needed — npm handles the build lifecycle
automatically.

Remove manual gitnexus-shared build steps from setup-gitnexus and
setup-gitnexus-web actions.

* fix(ci): build gitnexus-shared explicitly in setup actions

The file: dependency protocol doesn't reliably run prepare scripts
because devDependencies aren't installed first. Instead of fragile
lifecycle hacks, build gitnexus-shared explicitly in both setup actions:
- setup-gitnexus: npm install && npm run build in gitnexus-shared/
- setup-gitnexus-web: same, before npm ci in gitnexus-web/
- ci-tests: shared already built by setup-gitnexus, web just npm ci

No prepare script, no dist in git, no typescript as a prod dependency.

* fix: remove CALL from CYPHER_WRITE_RE — breaks FTS and vector search

CALL is used by read-only procedures: CALL QUERY_FTS_INDEX(...) and
CALL QUERY_VECTOR_INDEX(...). Adding it to the write guard blocked all
FTS search, causing 3 test failures. The database is opened in read-only
mode as defense-in-depth against write procedures via CALL.

Keep INSTALL and LOAD in the blocklist (genuinely dangerous).

* fix(web): update vercel.json for gitnexus-shared, remove COOP/COEP

- Add installCommand that builds gitnexus-shared before installing
  web deps (Vercel doesn't know about the monorepo file: dependency)
- Remove Cross-Origin-Opener-Policy and Cross-Origin-Embedder-Policy
  headers (no longer needed — WASM LadybugDB removed)

* fix(web): update tests for deleted modules

- Delete csv-generator.test.ts (tests deleted WASM-only csv-generator)
- Update security-guards.test.ts: import NODE_TABLES/REL_TYPES from
  gitnexus-shared instead of deleted src/core/lbug/schema
- Update server-connection.test.ts: import normalizeServerUrl from
  backend-client, remove extractFileContents tests (function deleted)

* fix(e2e): remove Server tab click — UI is now server-only

The DropZone no longer has ZIP/GitHub/Server tabs (browser ingestion
was removed). The server URL input is directly visible on the landing
page. Update e2e test to skip the tab click and go straight to input.

All 5 e2e tests pass locally.

* refactor: use gitnexus-shared for PipelinePhase/PipelineProgress types

CLI was duplicating PipelinePhase and PipelineProgress locally instead
of importing from gitnexus-shared. Updated all consumers to import
directly. Also removed dead code: SerializablePipelineResult,
serializePipelineResult(), deserializePipelineResult().

* fix(server): address PR #536 review — security, race conditions, dead code

- Fix path traversal in POST /api/analyze: split into isAbsolute + normalize check
- Add shared repo lock (activeRepoPaths) preventing concurrent analyze+embed on same repo
- Fix 202 response returning actual job.status instead of hardcoded 'queued'
- Add 30-minute timeout for embedding jobs (was missing unlike analyze jobs)
- Fix DropZone calling startAnalyze without setting backend URL first
- Add SSE reconnect with exponential backoff (3 retries) and Last-Event-ID
- Fix normalizeServerUrl to return base URL (no /api suffix) — clear contract
- Delete dead code: proxy.ts, server-graph-hydration.ts, pipeline.ts re-export barrel
- Update LoadingOverlay to import PipelineProgress directly from gitnexus-shared

* fix(server): fix repo lock key mismatch and embed cancel race

- Use getStoragePath(targetPath) as lock key in analyze handler to match
  embed handler's entry.storagePath — keys now always align
- Guard embed completion: don't overwrite 'failed' with 'complete' when
  job was cancelled while pipeline was still running
- Remove unused jobType parameter from acquireRepoLock
- Log backend.init() errors instead of silently swallowing

* fix: add gitnexus-shared as a local dependency in package-lock.json

* refactor: move language detection to gitnexus-shared, add syntax highlighting for all 15 languages

Move getLanguageFromFilename() from CLI to gitnexus-shared with COBOL
support added. Add getSyntaxLanguageFromFilename() for Prism-compatible
syntax highlighting covering all 15 code languages plus auxiliary
formats (json, yaml, markdown, html, css, bash, sql, xml).

Refactor CodeReferencesPanel to use shared function instead of a local
30-line switch. Delete dead gitnexus-web/src/config/supported-languages.ts
(web already imports SupportedLanguages from gitnexus-shared).

* feat(web): add first-time user onboarding with auto server detection

Replace the manual "Connect to Server" panel with an automatic onboarding
flow that guides first-time users through starting the GitNexus server.

Server detection:
- useBackend hook polls via setTimeout chain (3s, no overlap)
- Page Visibility API pauses polling when tab is hidden
- SSE heartbeat (/api/heartbeat) for instant disconnect detection

Onboarding UI (OnboardingGuide.tsx):
- Step-by-step flow: copy command → run → auto-connect
- Smart command: shows `gitnexus serve` in dev, `npx gitnexus@latest serve` in prod
- Node.js version auto-detected from package.json via Vite define
- Faux terminal windows with copy-to-clipboard, platform tabs, polling indicator

Transitions (DropZone.tsx):
- Crossfade wrapper with snapshot pattern for smooth phase transitions
- Three phases: onboarding → success (1.2s hold) → loading → graph
- Auto-recovery: falls back to onboarding if server dies or connect fails

Server changes:
- GET /api/heartbeat: SSE endpoint for liveness detection
- GET /api/info: version, launch context, Node.js version
- npm run serve script for local development
- app.disable('x-powered-by') hardening

* feat(web): add repo analysis UI, SSE heartbeat, and review fixes

Repo analysis:
- AnalyzeOnboarding: empty-state card when server has zero repos
- RepoAnalyzer: GitHub URL + Local Folder tabs with browse button
- Header repo dropdown: click project badge to switch repos or analyze new
- DropZone 'analyze' phase integrated into Crossfade transitions

Reliability fixes from 5-agent review:
- Polling: stop scheduling timers when tab hidden, restart on visibility return
- Heartbeat: exponential backoff (1s/2s/4s, 3 retries) prevents graph loss on blip
- RepoAnalyzer: completion timer tracked in ref, cleaned up on unmount
- DropZone: standardized card padding (p-7), heading sizes (text-lg)

Accessibility:
- prefers-reduced-motion global CSS rule (WCAG 2.3.3)
- focus-visible rings on CopyButton
- cursor-pointer on all Header buttons
- Consistent rounded-xl on all dropdowns

Cleanup:
- Deleted dead AnalyzeSheet.tsx (219 LOC) and BackendRepoSelector.tsx (89 LOC)
- Fixed AnalyzeProgress lucide import (lucide-react → @/lib/lucide-icons)

* fix(server): resolve analyze worker fork crash in dev mode

The forked analyze worker was crashing immediately with exit code 1
when running via `npm run serve` (tsx). Two issues:

1. Worker path resolved to `analyze-worker.js` but only `.ts` exists
   in the source directory — the `.js` file is only in `dist/`.

2. On Windows, bare `--import tsx` in execArgv fails because Node's
   ESM resolver for --import uses the child's CWD, not the parent's
   node_modules. Windows also rejects raw paths as `d:` is not a
   valid URL scheme.

Fix: detect dev vs prod via `import.meta.url` extension. In dev mode,
resolve `tsx/esm` to an absolute `file://` URL via `pathToFileURL()`
anchored to the parent's `createRequire` context. This works on all
platforms and doesn't depend on the child's CWD or PATH.

Also captures child stderr for better crash diagnostics.

Verified: `POST /api/analyze` with GitHub URL completes successfully
in dev mode (tsx) — status goes from cloning → analyzing → complete.

* fix(server): add worker auto-retry, error handling, and crash diagnostics

Worker resilience:
- Auto-retry up to 2 times with exponential backoff (1s, 2s) on crash
- SSE progress shows "Retrying after crash (1/2)..." during retry
- Captures child stderr for crash diagnostics in failure message
- AnalyzeJob tracks retryCount per job

Server error handling:
- app.listen wrapped in Promise so EADDRINUSE/EACCES propagate cleanly
- serve.ts catches startup errors with friendly messages and exit code 1
- EADDRINUSE gets actionable guidance (stop other process or --port flag)
- Global uncaughtException/unhandledRejection handlers prevent silent exits
- DEBUG=1 env var shows full stack traces

* feat: add e2e tests for onboarding flows, worker retry, and error handling

E2E tests (onboarding.spec.ts — 11 tests):
- Flow 1: OnboardingGuide shown when server unreachable (6 tests)
- Flow 2: Auto-connect with success card, analyze phase for zero repos
- Flow 3: Analyze form — GitHub URL validation, Local Folder tab, tab switching
- Flow 4: Repo dropdown in exploring view (skipped without live server)

Updated server-connect.spec.ts:
- Replaced manual Connect button flow with auto-connect waitForGraphLoaded

Server resilience:
- Worker auto-retry (2 attempts with exponential backoff) on crash
- Friendly error messages for serve startup failures (EADDRINUSE etc.)
- Global uncaughtException/unhandledRejection handlers prevent silent exits
- app.listen wrapped in Promise for proper error propagation

* refactor(shared): enforce exhaustive language coverage via Record types

Replace the if/else chain in getLanguageFromFilename with two exhaustive
Record<SupportedLanguages, ...> maps:

- EXTENSION_MAP: every language → its file extensions
- SYNTAX_MAP: every language → its Prism syntax identifier

Adding a new member to the SupportedLanguages enum without adding it to
both maps now produces a TypeScript compile error:

  Property '[SupportedLanguages.NewLang]' is missing in type...

This matches the existing pattern in languages/index.ts (providers table)
which already uses `satisfies Record<SupportedLanguages, LanguageProvider>`.

Three compile-time enforcement points now exist:
1. EXTENSION_MAP in language-detection.ts (file extensions)
2. SYNTAX_MAP in language-detection.ts (Prism syntax identifiers)
3. providers in languages/index.ts (LanguageProvider instances)

* feat(web): load source code from server and scroll to selected line

CodeReferencesPanel now fetches file content via GET /api/file when a
node is selected, instead of showing "Code not available in memory".

- Fetches via readFile() from backend-client when selectedFilePath changes
- Shows loading spinner while fetching
- After content loads, auto-scrolls to the selected node's startLine
- Highlights the selected line range with a cyan left border
- Cancels in-flight fetch if selection changes before it completes

Also: refactored language-detection.ts to use exhaustive Record types
(EXTENSION_MAP and SYNTAX_MAP) so adding a new SupportedLanguages enum
member without implementing extensions/syntax is a compile error.

* feat: buffered file reading for Code Inspector

Server: GET /api/file now supports ?startLine=N&endLine=M for reading
a line range instead of the entire file. Returns { content, startLine,
endLine, totalLines }.

Client: readFile() returns ReadFileResult with metadata. When selecting
a symbol (function, class, method), fetches only ±50 lines around the
symbol's startLine/endLine instead of the full file. File nodes still
fetch the entire file.

SyntaxHighlighter startingLineNumber set from the buffer offset so line
numbers are correct even for partial reads.

* fix: adapt readFile callers to new ReadFileResult return type

tools.ts: readFile comes from GraphRAGBackend interface which returns
Promise<string> (the adapter in useAppState extracts .content), so
revert the { content } destructuring back to plain string assignment.

useAppState.tsx: wrap backendReadFile with { repo } options object
and extract .content to satisfy the GraphRAGBackend interface.

* fix(web): ensure new repos appear in list immediately after analysis

Two fixes:

1. DropZone: handleAnalyzeComplete now passes the repoName through to
   connectToServer so the specific newly-analyzed repo loads — not the
   server's default first repo.

2. App.tsx: fetchRepos() is now awaited BEFORE handleServerConnect in
   both the DropZone and Header flows. This ensures the repo list is
   populated before the exploring view renders, so the new repo appears
   in the header dropdown immediately without a page reload.

* feat: delete repos, re-analyze with force, select after analysis

Server — DELETE /api/repo:
- Acquires repo lock first (409 if analyze/embed in flight)
- Closes LadybugDB, deletes index + clone dir, unregisters, re-inits
- Lock released in finally block

Server — analyze complete:
- backend.init() must succeed before SSE complete fires
- If backend.init() fails, job is marked failed (not complete)

Web — Header repo dropdown:
- Re-analyze: calls POST /api/analyze with force=true, shows spinning
  icon + inline progress bar via SSE
- Delete: acquires lock, aborts any running re-analysis SSE for same
  repo, refreshes list, switches to next repo
- After analysis completes: refreshes repo list, connects to the
  specific repo by name, loads graph, shows in explorer
- Retry with 1.5s backoff on 404 (server may still be reinitializing)

Type safety:
- err: any → err: unknown + instanceof BackendError in retry loop
- Added missing BackendRepo + BackendError imports in App.tsx

d07a69c3b1 fix(server): allow private/LAN network origins in CORS (#390)
Allow RFC 1918 private network ranges in the CORS origin allowlist so
users running GitNexus on their home or office LAN can access the web UI
from another device on the same network.

Permitted private ranges:
  10.0.0.0/8      (10.x.x.x)
  172.16.0.0/12   (172.16.x.x – 172.31.x.x)
  192.168.0.0/16  (192.168.x.x)

The origin check is extracted into an exported isAllowedOrigin() helper
so it can be unit-tested in isolation.  A new test file covers:
  - No origin (curl / server-to-server)
  - localhost and 127.0.0.1 variants
  - All three RFC 1918 ranges including boundary values
  - The deployed gitnexus.vercel.app site
  - Public / untrusted origins that must be rejected

The server bind address (127.0.0.1 by default) is unchanged; this PR
only affects which cross-origin browser requests are accepted.

Closes #390

refactor: migrate from KuzuDB to LadybugDB v0.15 (#275)
* refactor: migrate from KuzuDB to LadybugDB v0.15

KuzuDB was archived (Apple acquisition, Oct 2025). LadybugDB is the
community fork with full API compatibility.

- Package swap: kuzu → @ladybugdb/core, kuzu-wasm → @ladybugdb/wasm-core
- Rename all internal paths: kuzu → lbug (adapters, schema, storage)
- Storage path: .gitnexus/kuzu → .gitnexus/lbug (with auto-cleanup)
- Add explicit VECTOR extension loading (required in v0.15)
- Update CI workflow, documentation, and all tests
- 1151 unit + 27 integration tests passing

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: address code review findings (P1-P3)

P1: Fix WASM adapter to use getAll() API, wire cleanupOldKuzuFiles
into analyze command, add symlink path traversal protection.
P2: Cache VECTOR extension load state, batch augmentation engine
queries (20→4), fix web getCopyQuery for multi-language tables,
fix stale KuzuDB references, correct brainstorm package names.
P3: Complete lbug-wasm.d.ts type declarations, batch semantic
search per-label, update stale BM25 comment.

* chore: remove outdated KuzuDB migration brainstorming document

* fix: load FTS extension in MCP pool adapter on init

The read-only pool adapter never loaded the FTS extension, so all
QUERY_FTS_INDEX calls failed silently. This broke search-pool and
augmentation integration tests, and caused empty results in the
web UI server mode.

* feat: implement shared Database caching and connection reference counting

* feat: enhance KuzuDB migration handling and status reporting

* fix: mock cleanupOldKuzuFiles in local backend callTool tests

* fix: update mock for cleanupOldKuzuFiles and adjust imports in callTool tests

989673a624 fix: lazy-import embeddings to avoid onnxruntime crash on unsupported Node versions
Convert static imports of @huggingface/transformers (which triggers
onnxruntime-node native binary loading) to dynamic import() calls.
This prevents crashes on Node versions whose ABI isn't supported by
the prebuilt onnxruntime binaries (e.g. Node v24).

Affected entry points:
- cli/analyze.ts: embedding pipeline only loaded when --embeddings is passed
- mcp/local/local-backend.ts: embedder only loaded on first semantic search
- server/api.ts: embedder only loaded when search endpoint needs embeddings

Fixes #89

f047a84d82 fix(server): restore security guards and error handling
Address code review feedback on the server-mode PR:

Critical fixes:
- Restore CORS whitelist (localhost + gitnexus.vercel.app only)
- Bind to 127.0.0.1 by default; add --host CLI flag for opt-in remote access
- Restore path traversal guard on /api/file (resolve + startsWith check)
- Restore try/catch on all route handlers + global error middleware
- Restore SIGINT/SIGTERM graceful shutdown handlers

Bug fixes:
- Add mutex to core initKuzu to prevent race conditions on concurrent
  DB switches (two requests for different repos no longer corrupt state)
- Track ftsLoaded flag and reset on DB switch / close so FTS extension
  is reloaded for each new database connection
- Restore input validation on /api/query (cypher required) and
  /api/search (query required)

Improvements:
- Add TTL-based cleanup for orphaned MCP sessions (30min idle eviction)
  to prevent memory leaks from network drops that skip onclose

7ee2dd1087 feat: add remote server connection mode and multi-repo switching
Replace the old local-only backend mode with a new server connection
flow that lets the web UI connect to any running GitNexus server,
download the pre-built knowledge graph, and explore it without WASM.

- Add server-connection service with streaming download and progress
- Replace DropZone backend tab with server connect UI (URL input, progress bar, cancel)
- Add repo switcher dropdown in Header when multiple repos are indexed
- Mount MCP server over StreamableHTTP at /api/mcp for remote AI tool access
- Refactor api.ts to query KuzuDB directly instead of routing through LocalBackend
- Fix KuzuDB adapter to support switching between databases (close old before opening new)
- Extract createMCPServer() from startMCPServer() for transport-agnostic reuse
- Support ?server= query param for bookmarkable auto-connect

acd918f44e refactor(api): use executeCypher directly in buildGraph
Add public executeCypher(repoName, query) method to LocalBackend,
bypassing the callTool string dispatch and resolving the repo handle

a71924f774 fix: address PR review — CORS, search quality, and embedding flags
- Add https://gitnexus.vercel.app to CORS allowed origins so the
  deployed site can connect to the local backend server.
- Replace naive createHttpTextSearch (substring matching via Cypher)
  with createHttpHybridSearch that calls /api/search for full
  BM25 + semantic + RRF hybrid search on the server.
- Set isEmbeddingReady to false in backend mode (no local embedder),
  which also fixes {{QUERY_VECTOR}} handling — the existing error
  path in tools.ts now correctly returns a helpful message.
- Set isBM25Ready to true (available via server's hybrid search).
- Removes the Cypher injection bug (wrong escape char) since the
  function that contained it was replaced entirely.

8e8bb90fe4 refactor(serve): rewrite API server to use LocalBackend for multi-repo support
Replace direct single-repo KuzuDB access with LocalBackend, the same
backend the MCP server uses. The serve command now works with ALL
indexed repos via the global registry instead of only the CWD repo.

New/updated endpoints:
- GET /api/repos (list all indexed repos)
- GET /api/repo?name=X (repo metadata)
- GET /api/graph?repo=X (full knowledge graph)
- POST /api/query (raw Cypher via backend)
- POST /api/search (process-grouped search via backend)
- GET /api/file?repo=X&path=Y (file read with path traversal protection)
- GET /api/processes?repo=X, /api/process?repo=X&name=Y
- GET /api/clusters?repo=X, /api/cluster?repo=X&name=Y
