Weak LLMs routinely mangle high-entropy wiki slugs (especially UUID-based
summary/<id> slugs), producing dead cross-links and cross-item dedup
hallucinations. This tightens integrity end to end:
- Ingest dedup now groups each new item with only its own trigram
candidates and validates merges against that per-item scope, rejecting
cross-item mispairings; candidate top-K narrowed 20 -> 5.
- Editor path aliases out-link slugs behind low-entropy ref-N tokens and
translates them back after generation, removing the chance to mangle.
- Agent write tool normalizes/validates slugs, blocks manual creation of
system-owned summary pages, and auto-repairs dead [[slug]] links
(rewrite-only, never strips) via bigram/display-text resolution.
- llmresource registry aliases summary/<uuid> slugs the same way as
storage handles so they round-trip safely through chat.
Adds unit tests for slug validation, aliasing round-trip, dead-link
repair, and dedup rejection rules.
