Full Changelog: v0.3.0...v0.4.0

v0.3.0

Features

• Over-fetch-then-filter recall with visibility filtering (raw_k=max(k*5,50), max 2 retries)
• 13 admin endpoints for user/team/data management (/admin/user/*, /admin/team/*, /admin/stats, etc.)
• CLI commands: cortex user add/rotate-key/remove/list, cortex team create/add/remove/list, cortex admin stats/list-unowned/assign-owner
• Solo-to-team migration enhancement: pre-migration backup, per-table row counts, interactive owner prompt, cortex migrate --dry-run
• Graceful degradation across 7 failure scenarios: ONNX fallback with degraded_mode flag, team-mode MCP fail-closed, write-ahead buffer for offline stores, TLS solo/team mode distinction

Security

• ensure_auth_with_caller combines auth + identity resolution in single argon2 pass
• RecallContext threads visibility through entire recall pipeline (semantic, keyword, crystal, budget)
• Role-based admin auth via ensure_admin (owner/admin required)
• Table name allowlists prevent SQL injection in dynamic admin queries

Fixes

• unfold_source / GET /unfold now take RecallContext and filter by owner_id / visibility (fixes MCP unfold_source 3-arg mismatch and release CI build)
• Decision search in retry loop used hardcoded limit instead of fts_limit
• Fallback recall paths returned NULL owner_id causing visibility issues
• MCP handlers bypassed visibility by hardcoding solo context
• handle_user_add used re-query instead of last_insert_rowid()
• Removed tasks from archive/visibility allowlists (uses task_id TEXT, not id)

Known Issues

• MCP JSON-RPC lacks per-caller identity (uses default owner for all callers)
• is_visible treats NULL owner_id as visible in team mode (should fail closed after migration)
• Team-mode test environment needed to validate end-to-end

v0.2.0

Full Changelog: v0.1.0...v0.2.0

v0.1.0 -- First Public Release

Cortex v0.1.0 -- First Public Release

A persistent, self-improving brain for AI coding agents. Single Rust binary, zero runtime dependencies, in-process ONNX embeddings.

Highlights

• Capsule Compiler -- 97% token compression on boot (19K raw -> ~500 tokens)
• Hybrid Recall -- Semantic (ONNX embeddings) + keyword search with token budgeting
• Progressive Disclosure -- Peek -> Unfold -> Full recall at increasing token cost
• Conflict Detection -- Cosine + Jaccard flags contradictions between agents
• Score Decay -- Ebbinghaus-inspired memory aging keeps the brain sharp
• 13 MCP tools, 35+ HTTP endpoints, SSE event stream
• Multi-agent coordination -- session bus, file locking, task board, inter-agent messaging
• Windows Service support -- auto-start on boot with failure recovery
