v1.31.0

mk wander seed-selection fixes — surfaced by the first live wander dry-runs on real stores (Taj, Jun 11). Auto-seeds now reflect graph connectivity (citation weight) and span clusters (type diversity) instead of pulling session noise from one monoculture.

Added — mk wander type-diverse auto-seed selection (#281)

In a type-monoculture store (Taj's is ~90% beliefs), autoSeeds() returned the global top-N — all beliefs from one tight cluster — so the walk never escaped it and produced intra-cluster redundancy instead of the cross-cluster surprise spreading activation is meant to surface (observed live, Jun 11: 14/17 activated atoms from a single Apr-18–22 belief arc, zero cross-cluster collisions).

• src/wander.ts — autoSeeds() now draws seeds round-robin across atom types (best-ranked belief, then best fact, then best decision, …) so the seed set spans multiple clusters and the walk can bridge between them. Within each type, the citation-primary order from #280 is preserved. Reduces to plain top-N when only one type is present. Default on via the new WanderOptions.diverseSeeds (default true); CLI --no-diverse-seeds reverts to plain top-N. +3 tests (test/wander.test.ts).
• src/cli/mk.ts — new mk wander --no-diverse-seeds flag.

New public API (WanderOptions.diverseSeeds field + --no-diverse-seeds CLI flag) — sets the MINOR. (PR #286)

Out of scope (noted on #281): embedding-distance ("semantic surprise") collision scoring. Tier-1 wander is by-design LLM-free / pure-SQLite; embedding-backed scoring belongs to a future Tier-2 wander, not this change. The observed problem (walk stuck in one cluster) is fully addressed by type-diverse seeding.

Fixed — mk wander auto-seed selection was recency-biased, not citation-weighted (#280)

When no seeds were supplied, autoSeeds() ranked candidates purely by ACT-R base-level activation, ln(citations+1) − 0.5·ln(ageDays). Because ageDays is clamped to ≥0.01, an atom written in the current session earns a ≈+2.3 recency spike — enough to outrank a 28×-cited foundational atom. The result: wander consistently pulled the most-recently-touched atom as a seed regardless of graph connectivity, injecting session noise into spreading activation (observed live on Taj's store, Jun 11).

• src/wander.ts — autoSeeds() now ranks citation-primary: by raw citation_count descending, with base_activation only breaking ties among equally-cited atoms. A cited atom always outranks an uncited one as a seed. With no citation data (table unpopulated, or file-scan mode) the ranking degrades gracefully to pure recency. +2 regression tests (test/wander.test.ts). (PR #285)
