Implements Sub-Issue #87 of Issue #62 (Agent Memory System).
Core infrastructure:
- memory/types.py: Type definitions for all memory types (Working, Episodic,
Semantic, Procedural) with enums for MemoryType, ScopeLevel, Outcome
- memory/config.py: MemorySettings with MEM_ env prefix, thread-safe singleton
- memory/exceptions.py: Comprehensive exception hierarchy for memory operations
- memory/manager.py: MemoryManager facade with placeholder methods
Directory structure:
- working/: Working memory (Redis/in-memory) - to be implemented in #89
- episodic/: Episodic memory (experiences) - to be implemented in #90
- semantic/: Semantic memory (facts) - to be implemented in #91
- procedural/: Procedural memory (skills) - to be implemented in #92
- scoping/: Scope management - to be implemented in #93
- indexing/: Vector indexing - to be implemented in #94
- consolidation/: Memory consolidation - to be implemented in #95
Tests: 71 unit tests for config, types, and exceptions

Remove Temporal from the architecture in favor of the simpler
transitions + PostgreSQL + Celery approach. This aligns ADR-007
with ADR-010 based on user preference for simpler operations.
Key changes:
- ADR-007 now recommends transitions library instead of Temporal
- Added explicit "Why Not Temporal?" section explaining the trade-off
- Added "Reboot Survival" section documenting durability guarantees
- Updated architecture diagrams and component responsibilities
- Updated ARCHITECTURE.md summary matrix
The simpler approach is more appropriate for Syndarix's scale (10-50
concurrent agents) and uses existing PostgreSQL + Celery infrastructure.

- Added the following ADRs to `docs/adrs/` directory:
- ADR-001: MCP Integration Architecture
- ADR-002: Real-time Communication Architecture
- ADR-003: Background Task Architecture
- ADR-004: LLM Provider Abstraction
- ADR-005: Technology Stack Selection
- Each ADR details the context, decision drivers, considered options, final decisions, and implementation plans.
- Documentation aligns technical choices with architecture principles and system requirements for Syndarix.
- Update README.md with Syndarix vision, features, and architecture
- Update CLAUDE.md with Syndarix-specific context
- Create documentation directory structure:
- docs/requirements/ for requirements documents
- docs/architecture/ for architecture documentation
- docs/adrs/ for Architecture Decision Records
- docs/spikes/ for spike research documents
Built on PragmaStack template.
