+//! Claude Code CLI subprocess transport.
+//!
+//! Users with a Claude Code subscription already have OAuth credentials
+//! in ~/.claude/ and the `claude` binary on PATH. This module lets LLM
+//! Wiki reuse that subscription instead of requiring a separate API key.
+//! We treat `claude` purely as a text-completion engine — its agent
+//! tools, MCPs, file-edit abilities, and --resume session state are all
+//! out of scope. Multi-turn history is reconstructed from `messages`
+//! on every call, symmetric with every other provider.
+//!
+//! Why tokio::process directly (not tauri-plugin-shell): the plugin's
+//! scope model is designed for sidecars or fixed absolute paths; scoping
+//! a user-installed PATH binary cleanly is awkward. A hardcoded Rust
+//! command that always and only spawns `claude` provides the same
+//! security property (the webview can't call this command to execute
+//! anything else) without pulling in another plugin or editing
+//! capabilities JSON.

+Source pages also include:
+```yaml
+authors: []
+year: YYYY
+url: ""
+venue: ""
+```
+
+## Index Format
+
+`wiki/index.md` lists all pages grouped by type. Each entry:
+```
+- [[page-slug]] — one-line description
+```
+
+## Log Format
+
+`wiki/log.md` records research activity in reverse chronological order:
+```
+## YYYY-MM-DD
+
+- Action taken / finding noted
+```
+
+## Cross-referencing Rules
+
+- Use `[[page-slug]]` syntax to link between wiki pages
+- Every entity and concept should appear in `wiki/index.md`
+- Queries link to the sources and concepts they draw on
+- Synthesis pages cite all contributing sources via `related:`
+
+## Contradiction Handling
+
+When sources contradict each other:
+1. Note the contradiction in the relevant concept or entity page
+2. Create or update a query page to track the open question
+3. Link both sources from the query page
+4. Resolve in a synthesis page once sufficient evidence exists
