What's New

Auto-Context Injection

New mnemo inject command integrates with Claude Code's UserPromptSubmit hook — every prompt you type automatically searches past sessions and injects relevant context. Three modes:

  • off — no injection
  • helper — AI sees past sessions as helper context
  • assistant — AI sees past sessions as its own memory (recommended)

Configure with mnemo configure or during first-run onboarding.

QA Audit — 50 bugs fixed

Comprehensive audit covering error handling, type safety, and edge cases across all 35 source files.

Transaction Atomicity

All 12 indexers now use BeginTx() with atomic commit/rollback. No more partial session writes on errors.

Typed Return Structs

Replaced map[string]interface{} patterns with RecentSession, UsageStats, ToolUsageSummary, ModelUsageSummary — compile-time type safety for all callers.

Test Coverage

  • internal/db/ — 73.1% (up from 17.9%)
  • 8 new test files, 70+ tests covering transactions, FTS5 triggers, search ranking, token tracking, and edge cases

Key Fixes

  • rows.Err() checked after every for rows.Next() loop
  • All _ = patterns on fallible calls eliminated
  • Type assertion safety with comma-ok pattern throughout
  • Temporal decay: zero-timestamp fallback, future clamping, density caps
  • UTC normalization for all timestamp parsing
  • Streaming JSONL parser for large files (replaces io.ReadAll)
  • HTTP status code forwarding in proxy
  • Directory permissions hardened to 0700
  • UTF-8 safe string truncation

Architecture

  • execer interface abstracting *sql.DB and *sql.Tx
  • Tx variants: TxInsertSession, TxInsertMessage, TxInsertSessionSimple
  • Scan error logging with log.Printf
  • Godoc comments on all exported functions
