v0.7.0: Anticipated queries, origin trust, timeline filters

retrieval_hints (anticipated queries)

All record_* tools accept retrieval_hints: 2-4 alternate phrasings a future session might search for (synonyms, symptom descriptions, error messages). Indexed for both lexical and semantic retrieval -- the zero-dependency fix for vocabulary-mismatch queries. Field-proven on release day: two eval queries that store growth had crowded out of the top-5 recovered to rank 1 after their gold entries got hints (held-out hit@5 66.7% -> 80%, MRR 0.567 -> 0.700).

origin + trust weighting

Entries record who authored them: user (explicitly stated), agent (inferred, default), or import (backfilled). Retrieval scoring weights them 10/5/2, so a rule the user actually stated outranks one the agent guessed. Pre-v0.7 entries score as agent -- a uniform shift that preserves their relative order.

since / before temporal filters

get_context accepts ISO since/before bounds against each entry's verified/created timestamp. "What did we decide this month" is now a query.

Other MCP clients documented

The server is standard stdio MCP; README now has config snippets for Cursor, Codex CLI, Gemini CLI, and Windsurf. Only the hooks are Claude Code specific.
