v3.5.4

Fixed

• gh CLI compression safety — Unknown gh subcommands (gh pr diff, gh api, gh search, gh workflow, gh auth, gh secret, etc.) now pass through verbatim instead of being truncated to 10 lines. Previously, fallback compressors (JSON, log-dedup) could also strip content from gh api and gh search output. The fix returns Some(output) for unmatched commands (blocking fallback compression), matching the safe behavior already used by git and glab patterns.
• Uninstall proxy cleanup — lean-ctx uninstall now cleans up Claude Code (ANTHROPIC_BASE_URL in settings.json) and Codex CLI (OPENAI_BASE_URL in config.toml) proxy settings. Previously only shell exports (Gemini) were removed, leaving Claude/Codex pointing at the dead local proxy after uninstall. If a saved upstream exists, Claude Code settings are restored to the original URL.
• CLI ls/grep daemon path resolution — lean-ctx ls . and lean-ctx grep <pattern> . now resolve relative paths to absolute before sending to the daemon, fixing incorrect directory listings when the daemon's CWD differs from the CLI's CWD.

Added

• Context Bus v2: Multi-Agent Coordination — Major upgrade to the event bus with versioned events, causal lineage, consistency levels, and multi-agent conflict detection.
  • Event versioning: Every event now carries a monotonic version per (workspace, channel) and an optional parentId for causal chains.
  • Consistency levels: Events classified as local (informational), eventual (shared, async), or strong (requires sync) — enables agents to prioritize reactions.
  • K-bounded staleness guard: When a shared-mode agent falls behind by >10 events, tool responses include a [CONTEXT STALE] warning.
  • Knowledge conflict detection: Concurrent writes to the same knowledge key by different agents inject [CONFLICT] warnings before proceeding.
  • Enriched payloads: Event payloads now include path, category, key, and reasoning (from active session task) for richer observability.
  • SSE backfill on lag: When a broadcast subscriber falls behind, missed events are automatically backfilled from SQLite instead of dropped.
  • New REST endpoints: GET /v1/context/summary (materialized workspace view), GET /v1/events/search (FTS5 full-text search), GET /v1/events/lineage (causal chain traversal).
  • Team Server scopes expanded: ctx_session, ctx_knowledge, ctx_artifacts, ctx_proof, ctx_verify mapped to sessionMutations, knowledge, artifacts, search scopes.
  • Session race fix: SharedSessionStore::get_or_load uses atomic entry API to prevent TOCTOU races under concurrent agent loads.
• Configurable proxy upstreams — Teams routing through custom API gateways can now set proxy.anthropic_upstream, proxy.openai_upstream, and proxy.gemini_upstream via lean-ctx config set or environment variables. Upstreams are resolved once at proxy startup (env > config > default).
• Proxy upstream diagnostics — lean-ctx doctor validates proxy upstream URLs (self-referential loop detection, URL format) and reports which upstreams are active.
• 6 new adversarial compression tests — gh pr diff, gh api, gh search, gh workflow verbatim passthrough, plus shell-hook-level diff preservation test.

Changed

• Dry-run uninstall — lean-ctx uninstall --dry-run now previews Claude Code and Codex proxy cleanup actions.

Upgrade

lean-ctx update                 # recommended (auto-downloads + refreshes shell hooks)
cargo install lean-ctx          # or
npm update -g lean-ctx-bin      # or
brew upgrade lean-ctx

Note: After upgrading via cargo/npm/brew, run lean-ctx setup to refresh shell aliases. lean-ctx update does this automatically.
