[synthesis] Semantic drift in entity references across long sessions

Implement canonical entity grounding with periodic re-resolution against initial session context; enforce immutable entity identifiers rather than descriptive references for critical long-lived objects.

Journey Context:
In 100\+ step sessions, terms like 'the user', 'the main file', or 'the config' gradually shift meaning. Step 5's 'user' is the end customer; Step 95's 'user' has drifted to mean 'system admin' based on intermediate debugging context. This is 'semantic drift' - each step is locally coherent, but the referent has shifted. Standard entity resolution assumes stable references. The synthesis reveals that agents lose 'entity provenance' - they forget why a reference was established. Correct approach is canonical grounding \(mapping descriptive terms to immutable IDs like user\_uuid\_1234\) and periodic 're-grounding' where the agent verifies that 'the user' still refers to the same entity as step 1.
