Summary

This PR delivers two features for the Timmy sovereign AI agent system:

1. Thinking Engine Test Suite (#1314)

117 comprehensive tests across 21 test classes covering engine.py and all 4 mixins:

Module Tests Coverage Areas
ThinkingEngine (core) 32 init, think cycle, idle detection, user input recording, thought pruning, journal writing
ReflectionMixin 22 generate_reflection, emotional analysis, growth tracking, memory integration
DistillationMixin 18 distill_insights, pattern extraction, fact filtering/storage, memory_write integration
IssuesMixin 22 scan_for_issues, issue filing, severity classification, deduplication, resolution
InsightsMixin 23 generate_insight, depth scoring, cross-domain synthesis, relevance decay

Key testing patterns:

  • All LLM calls mocked via AsyncMock — tests run without Ollama
  • memory_write injected onto module object (not patch()) to match the try/except import pattern in distillation mixin
  • store_last_reflection similarly injected for reflection mixin tests
  • Proper async test support via pytest-asyncio

2. Sovereign Stack Manifest (#986)

  • docs/stack_manifest.json — 348 lines, 8 categories, 40+ tools with pinned versions, sovereignty scores, and migration notes
  • src/timmy/stack_manifest.pyquery_stack() tool with LRU caching and partial matching
  • Registered in src/timmy/tools/_registry.py as a sovereign tool
  • 24 tests covering query, caching, filtering, edge cases, and category listing

Test Results

141 new tests pass (117 engine + 24 manifest)
5365 total suite tests pass
ruff check: clean
48 pre-existing failures unchanged (quest_system, semantic_memory, kimi_delegation, etc.)

Files Changed

  • tests/timmy/test_thinking_engine.py — NEW (1350+ lines)
  • tests/timmy/test_stack_manifest.py — NEW (408 lines)
  • docs/stack_manifest.json — NEW (348 lines)
  • src/timmy/stack_manifest.py — NEW (161 lines)
  • src/timmy/tools/_registry.py — MODIFIED (added stack manifest registration)

Closes #1314, Closes #986
