explore_connections (chain, associations, bridges) returned empty results because
it read from CognitiveEngine in-memory data structures that were never populated.
memory_graph works because it queries SQLite directly via storage.get_memory_subgraph().
This rewrites explore.rs to follow the same pattern as graph.rs:
- Remove CognitiveEngine dependency, use Storage directly
- associations: queries depth-1 subgraph for neighbors
- chain: pulls neighborhoods around both endpoints, builds adjacency list,
runs BFS with priority queue (ported from chains.rs algorithm)
- bridges: reuses chain logic, extracts intermediate nodes by frequency
Also updates the call site in server.rs to pass storage instead of cognitive.
Adds integration tests that insert actual connections and verify non-empty results.

Includes HN post with prepared FAQ, Reddit cross-posts (r/rust, r/ClaudeAI,
r/LocalLLaMA), MCP Dev Summit demo scripts (30s/3min/10min versions), and
technical blog post covering FSRS-6, PE Gating, HyDE, STC, and dreaming.

Triggers 2 (force after 6h stale) and 3 (mini-consolidation after 2h)
fired immediately on fresh schedulers even when user was active, because
they didn't check activity state. Added MIN_BRIEF_IDLE_MINS (5 min)
guard so both triggers require a brief idle period before firing.
Fixes test_consolidation_idle_trigger in CI.

Discovered that Xcode's claudeai-mcp feature gate blocks custom MCP
servers from the global .claude config. Project-level .mcp.json files
bypass this gate entirely — this is now the documented method.
- Add scripts/xcode-setup.sh: auto-installs vestige-mcp and configures
.mcp.json for any Xcode project with checksum verification
- Rewrite docs/integrations/xcode.md with .mcp.json method, gate bypass
docs, and new troubleshooting for "Agent has been closed" error
- Add docs/blog/xcode-memory.md: launch blog post for Vestige on Xcode
- Add integration guides for Xcode 26.3, Cursor, VS Code, JetBrains, Windsurf
- First cognitive memory server with documented Xcode 26.3 MCP support
- Add npx @vestige/init — zero-config CLI that auto-detects IDEs and injects config
- Overhaul README: "The open-source cognitive engine for AI"
- Add "Why Not Just Use RAG?" comparison and cognitive science stack docs
- Update license badge to AGPL-3.0
3 new MCP tools (16 → 19 total):
- importance_score: 4-channel neuroscience importance scoring (novelty/arousal/reward/attention)
- session_checkpoint: batch smart_ingest up to 20 items with PE Gating
- find_duplicates: cosine similarity clustering with union-find for dedup
CLI: vestige ingest command for memory ingestion via command line
Core: made get_node_embedding public, added get_all_embeddings for dedup scanning

Add web dashboard (axum) on port 3927 with memory browser, search, and
system stats. New MCP tools: memory_timeline, memory_changelog,
health_check, consolidate, stats, backup, export, gc. Search now supports
detail_level (brief/summary/full) to control token usage. Add backup_to()
and get_recent_state_transitions() to storage layer. Bump to v1.2.0.
P0 fixes:
- Add `vestige backup <path>` — full DB copy with WAL checkpoint flush
- Add `vestige export --format json|jsonl [--tags] [--since] <path>` —
paginated memory export with tag/date filtering
- Add `vestige gc --min-retention 0.1 [--max-age-days] [--dry-run] [--yes]`
— bulk cleanup of stale memories with safety prompts
- Fix apply_decay() scaling: batched pagination (500 rows/batch) with
explicit transactions instead of loading all nodes into memory
- Fix hidden MCP resources: memory://insights and memory://consolidation-log
now listed in resources/list (were implemented but undiscoverable)
P1 fixes:
- Add auto-consolidation on server startup: FSRS-6 decay runs in background
after 2s delay, only if last consolidation was >6 hours ago
- Add encryption at rest via SQLCipher feature flag: use --features encryption
with VESTIGE_ENCRYPTION_KEY env var (bundled-sqlite and encryption are
mutually exclusive)

- Route ingest tool through smart_ingest (Prediction Error Gating) to
prevent duplicate memories when content is similar to existing entries
- Fix Intel Mac release build: use macos-13 runner for x86_64-apple-darwin
(macos-latest is now ARM64, causing silent cross-compile failures)
- Sync npm package version to 1.1.2 (was 1.0.0 in package.json, 1.1.0
in postinstall.js BINARY_VERSION)
- Add vestige-restore to npm makeExecutable list
- Remove abandoned packages/core/ TypeScript package (pre-Rust implementation
referencing FSRS-5, chromadb, ollama — 32K lines of dead code)
- Sync workspace Cargo.toml version to 1.1.2
Closes#5

Previously, fastembed created .fastembed_cache in the current working
directory, polluting project folders with symlinks.
Now uses platform-appropriate cache directories:
- macOS: ~/Library/Caches/com.vestige.core/fastembed
- Linux: ~/.cache/vestige/fastembed
- Windows: %LOCALAPPDATA%\vestige\cache\fastembed
Can still be overridden with FASTEMBED_CACHE_PATH env var.
Fixes user feedback about .fastembed_cache appearing in random folders.

- Fix silent errors in stdio.rs: clients now receive fallback error
responses instead of hanging when JSON serialization fails
- Fix UTF-8 panics in keyword.rs: use char-aware slicing instead of
byte offsets for query sanitization and term highlighting
- Fix UTF-8 panics in prospective_memory.rs: replace hard-coded byte
offsets with char-aware slicing for natural language parsing
- Fix UTF-8 panics in git.rs: convert byte positions to char positions
before slicing commit messages
- Fix feature flag bug in vestige-mcp: add proper [features] section
to forward embeddings and vector-search features from vestige-core,
enabling the #[cfg(feature = "embeddings")] initialization code
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
When embeddings fail to initialize in the MCP server context (e.g., due
to working directory issues), the error was silently swallowed and
smart_ingest would fall back to regular ingest without explanation.
Changes:
- Add init_embeddings() method to Storage for explicit initialization
- Initialize embeddings at MCP server startup with error logging
- Add check_ready() method to EmbeddingService for error access
- Log warning when is_ready() returns false
Now users will see clear error messages like:
"Failed to initialize embedding service: ..."
"Hint: Check FASTEMBED_CACHE_PATH or ensure ~/.fastembed_cache exists"

Claude Desktop requests protocol version 2025-06-18 but Vestige was
responding with 2025-11-25, causing Claude Desktop to disconnect.
Now the server negotiates: if the client requests an older version,
use it. This maintains backward compatibility with older clients.
Fixes: Claude Desktop "Server transport closed unexpectedly" error

Users were seeing 30 tools in /mcp which was overwhelming. Now only 8
essential tools are listed:
1. search - unified hybrid search
2. memory - get/delete/state operations
3. codebase - patterns and decisions
4. intention - prospective memory
5. ingest - add memories
6. smart_ingest - intelligent ingestion
7. promote_memory - thumbs up
8. demote_memory - thumbs down
Deprecated tools (recall, semantic_search, etc.) still work internally
for backward compatibility but are no longer listed.

Two distribution methods now available:
1. npm (for Claude Code / developers):
npm install -g vestige-mcp-server
claude mcp add vestige vestige-mcp -s user
2. MCPB (for Claude Desktop / one-click install):
Download vestige-1.1.0.mcpb from releases, double-click
Changes:
- Renamed npm package to vestige-mcp-server (vestige-mcp was taken)
- Fixed postinstall to download binaries from GitHub releases
- Added vestige-mcpb package with manifest and build script
- Uploaded .mcpb bundle to v1.1.0 release

The npm package was missing the actual binary download step - users got
wrapper scripts pointing to non-existent binaries.
Changes:
- postinstall.js now downloads correct binary from GitHub releases
- Added vestige.js wrapper for CLI binary
- Exposed both vestige-mcp and vestige commands in package.json
- Updated README with troubleshooting, storage info, CLI docs
- Added .gitignore for downloaded binaries
Fixes fresh install issues where Claude Desktop couldn't attach and
vestige CLI wasn't found.

Drop problematic targets:
- x86_64-apple-darwin: No free Intel macOS runners after macos-13 retirement
- aarch64-unknown-linux-gnu: Cross-compile OpenSSL issues with vendored feature
Ship with 2 platforms that work reliably:
- aarch64-apple-darwin (macOS Apple Silicon)
- x86_64-unknown-linux-gnu (Linux x86_64)
Users on Intel Mac or ARM64 Linux can build from source with cargo.

Two-pronged fix for cross-compilation:
1. git2 with vendored-openssl feature - compiles OpenSSL from source,
eliminating system dependency issues across all platforms
2. houseabsolute/actions-rust-cross@v1 - dedicated GitHub Action that
properly handles cross-compilation with Docker containers
