- New spectral module: Laplacian eigendecomposition of the memory graph.
Commands: spectral, spectral-save, spectral-neighbors, spectral-positions,
spectral-suggest. Spectral neighbors expand search results beyond keyword
matching to structural proximity.
- Search: use StoreView trait to avoid 6MB state.bin rewrite on every query.
Append-only retrieval logging. Spectral expansion shows structurally
nearby nodes after text results.
- Fix panic in journal-tail: string truncation at byte 67 could land inside
a multi-byte character (em dash). Now walks back to char boundary.
- Replay queue: show classification and spectral outlier score.
- Knowledge agents: extractor, challenger, connector prompts and runner
scripts for automated graph enrichment.
- memory-search hook: stale state file cleanup (24h expiry).
Three new tools for structural graph health:
- fix-categories: rule-based recategorization fixing core inflation
(225 → 26 core nodes). Only identity.md and kent.md stay core;
everything else reclassified to tech/obs/gen by file prefix rules.
- cap-degree: two-phase degree capping. First prunes weakest Auto
edges, then prunes Link edges to high-degree targets (they have
alternative paths). Brought max degree from 919 → 50.
- link-orphans: connects degree-0/1 nodes to most textually similar
connected nodes via cosine similarity. Linked 614 orphans.
Also: community detection now filters edges below strength 0.3,
preventing weak auto-links from merging unrelated communities.
Pipeline updated: consolidate-full now runs link-orphans + cap-degree
instead of triangle-close (which was counterproductive — densified
hub neighborhoods instead of building bridges).
Net effect: Gini 0.754 → 0.546, max degree 919 → 50.
- All partial_cmp().unwrap() → unwrap_or(Ordering::Equal) to prevent
NaN panics in sort operations across neuro.rs, graph.rs, similarity.rs
- replay_queue_with_graph: accepts pre-built graph, avoids rebuilding
in agent_prompt (was building 2-3x per prompt)
- differentiate_hub_with_graph: same pattern for differentiation
- Simplify double-reverse history iteration to slice indexing

Zero warnings on `cargo clippy`.
- Replace all 5 `Command::new("date")` calls across 4 files with
pure Rust time formatting via libc localtime_r
