From f2f8602686846ba9f47342f20082175d5428466c Mon Sep 17 00:00:00 2001 From: Steven Enamakel Date: Thu, 13 Aug 2026 16:09:29 +0300 Subject: [PATCH 01/80] feat(people): add address book module with migration, resolver, scorer, and store Introduces a new address book feature for managing people, including a SQL migration for initial schema setup, a resolver for looking up contacts, a scorer for ranking relevance, and a store for persistence. This change also adds the corresponding types and tests to support the module.

The method also supports excluding a session's auto-saved documents to prevent self-echo during mid-turn searches. The null provider returns unsupported, while the module provider delegates to the unified store and the service exposes it as a bus operation.

This change ensures that the capability version is properly extracted and passed through the registration flow, aligning with the protocol specification.

Two of the archivist's eight engine calls took no connection at all — +//! deciding *whether* a new turn starts a new segment, and composing a summary +//! when no model is available. Neither touches storage, so both stay host-side +//! in `agent::harness::archivist`, next to the recap logic and the boundary +//! thresholds they read.

The old code inserted a row and then issued `SELECT last_insert_rowid()` on +//! the same connection to learn its id. That is two operations relying on a +//! *connection-local* side effect, and it is wrong the moment anything else +//! shares the connection or the two hops cross a bus — `last_insert_rowid` is +//! per-connection state, so an interleaved insert from another task yields the +//! wrong id and the turn is filed under the wrong segment. +//! +//!
