ccmux v0.1.19

session-reader library seam — expose the tested block-parser as 'ccmux/session-reader' for external consumers (readSession/parseSession/detect + types), lean (no ink/react), inert for the fleet bundle

• Expose the transcript reader as a library — ccmux/session-reader (src/lib.ts + a package.json
  exports subpath). readSession(path, agent, textLimit?) / parseSession(lines, agent, textLimit?)
  / detect(lines) plus the TranscriptMessage types, so an external consumer reuses the tested,
  agent-agnostic (Claude + Codex) block-parser instead of duplicating it. textLimit is a passthrough
  (default 6000; pass higher for full-text indexing). Lean by construction: the seam wires only the
  PURE parsers + readLines + types, so importing it pulls in zod + node:fs — not ink/react/tmux
  (verified: src/lib.ts bundles to ~15 KB with zero ink/react in the subgraph). Inert for the fleet:
  the shipped bundle is built from cli.ts, and exports only affects external import "ccmux/…"
  resolution. The format sniff moved to src/agent/detect.ts (normalize-only deps) and is re-exported
  from agent/index.ts under its existing name.
