- memory_system.py: fix regex replacement in update_user_profile()
Used lambda instead of raw replacement string to prevent corruption
- memory_system.py: add guards to update_section() for empty/oversized writes
Ref #39
Consolidates 3 separate memory databases (semantic_memory.db, swarm.db
memory_entries, brain.db) into a single data/memory.db with facts,
chunks, and episodes tables.
Key changes:
- Add unified schema (timmy/memory/unified.py) with 3 core tables
- Redirect vector_store.py and semantic_memory.py to memory.db
- Add thought distillation: every Nth thought extracts lasting facts
- Enrich agent context with known facts in system prompt
- Add memory_forget tool for removing outdated memories
- Unify embeddings: vector_store delegates to semantic_memory.embed_text
- Bridge spark events to unified event log
- Add pruning for thoughts and events with configurable retention
- Add data migration script (timmy/memory_migrate.py)
- Deprecate brain.memory in favor of unified system

Wire MEMORY.md + soul.md into the thinking loop so each heartbeat
is grounded in identity and recent context, breaking repetitive loops.
Pre-hook: _load_memory_context() reads hot memory first (changes each
cycle) then soul.md (stable identity), truncated to 1500 chars.
Post-hook: _update_memory() writes a "Last Reflection" section to
MEMORY.md after each thought so the next cycle has fresh context.
soul.md is read-only from the heartbeat — never modified by it.
All hooks degrade gracefully and never crash the heartbeat.

* polish: streamline nav, extract inline styles, improve tablet UX
- Restructure desktop nav from 8+ flat links + overflow dropdown into
5 grouped dropdowns (Core, Agents, Intel, System, More) matching
the mobile menu structure to reduce decision fatigue
- Extract all inline styles from mission_control.html and base.html
notification elements into mission-control.css with semantic classes
- Replace JS-built innerHTML with secure DOM construction in
notification loader and chat history
- Add CONNECTING state to connection indicator (amber) instead of
showing OFFLINE before WebSocket connects
- Add tablet breakpoint (1024px) with larger touch targets for
Apple Pencil / stylus use and safe-area padding for iPad toolbar
- Add active-link highlighting in desktop dropdown menus
- Rename "Mission Control" page title to "System Overview" to
disambiguate from the chat home page
- Add "Home — Timmy Time" page title to index.html

* fix(security): move auth-gate credentials to environment variables
Hardcoded username, password, and HMAC secret in auth-gate.py replaced
with os.environ lookups. Startup now refuses to run if any variable is
unset. Added AUTH_GATE_SECRET/USER/PASS to .env.example.

* refactor(tooling): migrate from black+isort+bandit to ruff
Replace three separate linting/formatting tools with a single ruff
invocation. Updates tox.ini (lint, format, pre-push, pre-commit envs),
.pre-commit-config.yaml, and CI workflow. Fixes all ruff errors
including unused imports, missing raise-from, and undefined names.
Ruff config maps existing bandit skips to equivalent S-rules.

Discord created a new agent per message with no conversation history,
causing Timmy to lose context between messages (the "yes" bug). Now uses
a singleton agent with per-channel/thread session_id, matching the
dashboard's session.py pattern. Also applies _clean_response() to strip
hallucinated tool-call JSON from Discord output.
Additional fixes:
- get_system_context() no longer clears the handoff file (was destroying
session context on every agent creation)
- Orchestrator uses HotMemory.read() to auto-create MEMORY.md if missing
- vector_store DB_PATH anchored to __file__ instead of relative CWD
- brain/schema.py: removed invalid .load dot-commands from INIT_SQL
- tools_intro: fixed wrong table name 'vectors' → 'chunks' in tier3 check

This commit replaces the previous memory_layers.py with a proper three-tier
memory system as specified by the user:
## Tier 1 — Hot Memory (MEMORY.md)
- Single flat file always loaded into system context
- Contains: current status, standing rules, agent roster, key decisions
- ~300 lines max, pruned monthly
- Managed by HotMemory class
## Tier 2 — Structured Vault (memory/)
- Directory with three namespaces:
• self/ — identity.md, user_profile.md, methodology.md
• notes/ — session logs, AARs, research
• aar/ — post-task retrospectives
- Markdown format, Obsidian-compatible
- Append-only, date-stamped
- Managed by VaultMemory class
## Handoff Protocol
- last-session-handoff.md written at session end
- Contains: summary, key decisions, open items, next steps
- Auto-loaded at next session start
- Maintains continuity across resets
## Implementation
### New Files:
- src/timmy/memory_system.py — Core memory system
- MEMORY.md — Hot memory template
- memory/self/*.md — Identity, user profile, methodology
### Modified:
- src/timmy/agent.py — Integrated with memory system
- create_timmy() injects memory context
- TimmyWithMemory class with automatic fact extraction
- tests/test_agent.py — Updated for memory context
## Key Principles
- Hot memory = small and curated
- Vault = append-only, never delete
- Handoffs = continuity mechanism
- Flat files = human-readable, portable
## Usage
All 973 tests pass.
