Remove dead feature gate references from documentation #2098
Description
Summary
8 feature flags are referenced in documentation (CLAUDE.md, README.md) as feature gates, but have zero #[cfg(feature)] annotations in any .rs file. The code compiles unconditionally regardless of whether these features are specified. The documentation references are misleading.
Dead Feature Gates
| Feature | Evidence |
|---|---|
graph-memory |
petgraph is non-optional dep; SYNAPSE, BFS, entities all compile unconditionally |
orchestration |
zeph-orchestration is non-optional dep of zeph-core |
self-learning |
FeedbackDetector, Wilson score, BM25+RRF compile unconditionally |
qdrant |
qdrant-client is non-optional dep of zeph-memory and zeph-skills |
router |
Thompson Sampling, cascade routing, RAPS all compile unconditionally |
vault-age |
age backend compiles unconditionally |
openai |
OpenAI provider compiles unconditionally |
compatible |
Compatible provider compiles unconditionally |
Stability Evidence
All verified across 15+ CI sessions (CI-1 through CI-61). Zero open bugs for any of these subsystems.
Scope
- Update
CLAUDE.md"Always-on features" and "Optional features" lists - Update
README.mdfeature documentation - Clarify which features are always-on vs genuinely feature-gated
- No Cargo.toml or code changes needed
