Adds the observability + safety layer that turns AtoCore from
"works until something silently breaks" into "every mutation is
traceable, drift is detected, failures raise alerts."
1. Audit log (memory_audit table):
- New table with id, memory_id, action, actor, before/after JSON,
note, timestamp; 3 indexes for memory_id/timestamp/action
- _audit_memory() helper called from every mutation:
create_memory, update_memory, promote_memory,
reject_candidate_memory, invalidate_memory, supersede_memory,
reinforce_memory, auto_promote_reinforced, expire_stale_candidates
- Action verb auto-selected: promoted/rejected/invalidated/
superseded/updated based on state transition
- "actor" threaded through: api-http, human-triage, phase10-auto-
promote, candidate-expiry, reinforcement, etc.
- Fail-open: audit write failure logs but never breaks the mutation
- GET /memory/{id}/audit: full history for one memory
- GET /admin/audit/recent: last 50 mutations across the system
2. Alerts framework (src/atocore/observability/alerts.py):
- emit_alert(severity, title, message, context) fans out to:
- structlog logger (always)
- ~/atocore-logs/alerts.log append (configurable via
ATOCORE_ALERT_LOG)
- project_state atocore/alert/last_{severity} (dashboard surface)
- ATOCORE_ALERT_WEBHOOK POST if set (auto-detects Discord webhook
format for nice embeds; generic JSON otherwise)
- Every sink fail-open — one failure doesn't prevent the others
- Pipeline alert step in nightly cron: harness < 85% → warning;
candidate queue > 200 → warning
3. Integrity checks (scripts/integrity_check.py):
- Nightly scan for drift:
- Memories → missing source_chunk_id references
- Duplicate active memories (same type+content+project)
- project_state → missing projects
- Orphaned source_chunks (no parent document)
- Results persisted to atocore/status/integrity_check_result
- Any finding emits a warning alert
- Added as Step G in deploy/dalidou/batch-extract.sh nightly cron
4. Dashboard surfaces it all:
- integrity (findings + details)
- alerts (last info/warning/critical per severity)
- recent_audit (last 10 mutations with actor + action + preview)
Tests: 308 → 317 (9 new):
- test_audit_create_logs_entry
- test_audit_promote_logs_entry
- test_audit_reject_logs_entry
- test_audit_update_captures_before_after
- test_audit_reinforce_logs_entry
- test_recent_audit_returns_cross_memory_entries
- test_emit_alert_writes_log_file
- test_emit_alert_invalid_severity_falls_back_to_info
- test_emit_alert_fails_open_on_log_write_error
Deferred: formal migration framework with rollback (current additive
pattern is fine for V1); memory detail wiki page with audit view
(quick follow-up).
To enable Discord alerts: set ATOCORE_ALERT_WEBHOOK to a Discord
webhook URL in Dalidou's environment. Default = log-only.

AtoCore
Personal context engine that enriches LLM interactions with durable memory, structured context, and project knowledge.
Quick Start
pip install -e .
uvicorn src.atocore.main:app --port 8100
Usage
# Ingest markdown files
curl -X POST http://localhost:8100/ingest \
-H "Content-Type: application/json" \
-d '{"path": "/path/to/notes"}'
# Build enriched context for a prompt
curl -X POST http://localhost:8100/context/build \
-H "Content-Type: application/json" \
-d '{"prompt": "What is the project status?", "project": "myproject"}'
# CLI ingestion
python scripts/ingest_folder.py --path /path/to/notes
# Live operator client
python scripts/atocore_client.py health
python scripts/atocore_client.py audit-query "gigabit" 5
API Endpoints
| Method | Path | Description |
|---|---|---|
| POST | /ingest | Ingest markdown file or folder |
| POST | /query | Retrieve relevant chunks |
| POST | /context/build | Build full context pack |
| GET | /health | Health check |

Architecture
FastAPI (port 8100)
|- Ingestion: markdown -> parse -> chunk -> embed -> store
|- Retrieval: query -> embed -> vector search -> rank
|- Context Builder: retrieve -> boost -> budget -> format
|- SQLite (documents, chunks, memories, projects, interactions)
'- ChromaDB (vector embeddings)
Configuration
Set via environment variables (prefix ATOCORE_):
| Variable | Default | Description |
|---|---|---|
| ATOCORE_DEBUG | false | Enable debug logging |
| ATOCORE_PORT | 8100 | Server port |
| ATOCORE_CHUNK_MAX_SIZE | 800 | Max chunk size (chars) |
| ATOCORE_CONTEXT_BUDGET | 3000 | Context pack budget (chars) |
| ATOCORE_EMBEDDING_MODEL | paraphrase-multilingual-MiniLM-L12-v2 | Embedding model |
Testing
pip install -e ".[dev]"
pytest
Operations
scripts/atocore_client.pyprovides a live API client for project refresh, project-state inspection, and retrieval-quality audits.docs/operations.mdcaptures the current operational priority order: retrieval quality, Wave 2 trusted-operational ingestion, AtoDrive scoping, and restore validation.
