v3.9.5

Fixed

• Prompt-cache invalidation via additionalContext injection (GH #778).
  PostToolUse [CODE HEALTH] notices and PreToolUse shadow-mode nudges injected
  text into additionalContext on every qualifying event. On Anthropic models
  this retroactively mutates the cached prefix, causing 440–520k tokens of cache
  re-bills per injection. Fix: default inject_context = false in [code_health]
  config — notices now route to ctx_knowledge and the ContextBus (dashboard).
  Opt-in via [code_health] inject_context = true or LEAN_CTX_INJECT_CONTEXT=1.
• Marker contamination in source files — root-cause fix. The redirect-suffix
  (--- lean-ctx: ctx_compose ...) was appended directly to .lctx temp files.
  When agents copied temp-file content back into source, the marker leaked into
  .rs/.js/.sh files, breaking builds. Fix: the suffix is never written to
  file content; the nudge travels exclusively via additionalContext (gated by
  inject_context) or is suppressed entirely.
• Release pipeline: rmcp crates.io compile bug. rmcp 2.2.0 on crates.io
  calls SseStream::from_bytes_stream but sse-stream 0.2.x only provides
  from_byte_stream. Restored [patch.crates-io] to upstream git rev 67a3085
  which has the fix; cargo publish --no-verify bypasses broken verification.
• Release pipeline: Homebrew SHA256 grep collision. The grep pattern
  x86_64-unknown-linux-gnu also matched the -cuda variant, producing
  multiple SHA256 values and breaking the GitHub Actions output format. Fixed
  with .tar.gz suffix anchoring.

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.
