* fix: 4 corrections — streaming hash, watchdog bug, cipher doc, depsChristophe Besson2026-08-091-1/+12
| | | | | | | | | | | | | | | | | | | 1. indexer.py: streaming blake3 (8MB chunks) instead of read_bytes(). Large files (initrd.img, ISOs, VM images) no longer load into RAM. 2. QE/demo-v1/run_node.py: call indexer.start() not initial_scan(). initial_scan() alone never starts the watchdog observer — files added after startup were silently ignored. Added indexer.stop() on shutdown. 3. USERGUIDE.md §8: clarify symmetric vs asymmetric. Ed25519/X25519 = asymmetric (key pairs). ChaCha20-Poly1305 and AES-256-GCM = symmetric AEAD 256-bit (content encryption). ChaCha20 is PRIMARY; AES-GCM is optional browser-compat variant only. 4. pyproject.toml: aioquic, websockets, aiosqlite, slowapi added to proper package deps (were installed manually, now declared).

* fix: complete pyproject.toml deps + graceful QUIC fallbackChristophe Besson2026-08-091-8/+21
| | | | | | | | | | | | | | | | | | | | meshbay-node/pyproject.toml: add aioquic>=1.0 (was commented 'v2'), websockets>=12.0 (revocation push). Both are production code since Phase 5. meshbay-hub/pyproject.toml: add aiosqlite (tests without PostgreSQL), slowapi (rate limiting), websockets (revocation push), PyJWT (explicit). transport/__init__.py: QUIC imports wrapped in try/except — node works without aioquic (TCP+TLS + HTTP fallback). QUIC_AVAILABLE flag exported. QUICKSTART.md: replace manual pip list with 'pip install -e' that pulls all deps from pyproject.toml automatically. Add dependency table. CLAUDE.md: clarify that all deps go in pyproject.toml, not manual installs. 81/81 tests. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
* fix: venv --clear required when copying repo across OS (Fedora→Ubuntu)Christophe Besson2026-08-091-11/+8
| | | | | | | | | | | | | Root cause: certifi.where() in the Fedora venv points to /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem which does not exist on Ubuntu. 'python3 -m venv .venv' without --clear keeps the Fedora certifi paths. Fix: always use --clear when recreating a venv on a different OS. Documented in QUICKSTART.md and CLAUDE.md. rsync command updated to exclude .venv/ (in QE/server-state, not versioned). Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
* fix: document pip SSL_CERT_FILE workaround for Python 3.14 on Ubuntu/FedoraChristophe Besson2026-08-091-4/+17
| | | | | | | | pip + Python 3.14 fails with FileNotFoundError in certifi.where() on fresh venvs (truststore bug). Fix: SSL_CERT_FILE pointing to system CA bundle. Documented in CLAUDE.md (Python environment section) and QUICKSTART.md. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
* docs: update all pointers after keyderive + QE restructureChristophe Besson2026-08-092-8/+64
| | | | | | | | | | | | | | | | | | | | | | CLAUDE.md: add QE/ to structure, key modules table, server state reference, security rule updated (QE/ not keypair files), meshbay.org inventory pointer. devel-phases.md: add milestones 6.6-6.9 (keyderive, bundle, demo scripts, QUICKSTART rewrite). 81/81 tests. docs/meshbay-draft-v3.md §6.1.1: new section documenting 3 key generation strategies (Argon2id CLI, WebCrypto browser+bundle, keystore file) and the algorithm mismatch caveat between CLI and web registration paths. docs/USERGUIDE.md §2 Register+Login: replace "generate and persist before registering" warning with the two clean strategies (derive_keys_from_password for CLI, keyderive.js + keypair_bundle for browser). Login response updated with keypair_bundle field. hub/models.py + users.py + Alembic migration: keypair_bundle column on User, stored at registration, returned at login (web clients only). Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
* feat: password-based key derivation + operational QUICKSTARTChristophe Besson2026-08-091-358/+141
| | | | | | | | | | | | | | | | | | | | | keyderive.py: derive Ed25519+X25519 from username+password via Argon2id. Same credentials → same keys on any device. Encrypt/decrypt keypair bundle (AES-256-GCM) for hub storage (web clients). 7/7 tests. Full suite: 81/81. keyderive.js: browser counterpart using PBKDF2-SHA512 + random keypairs encrypted for hub storage. Avoids algorithm mismatch with Python. hub/models.py + users.py: keypair_bundle field added to User, stored on registration, returned in login response for web client key recovery. QUICKSTART.md: fully rewritten. 3 operational scripts in QE/demo-v1/: setup_demo.py — create accounts, group, distribute GEK run_node.py — start HTTP node (watches shared/ directory) download.py — bob login → GEK fetch → decrypt → save All tested locally end-to-end. No invented URLs. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
* docs: add QUICKSTART.md and USERGUIDE.mdChristophe Besson2026-08-092-0/+1219
| | | | | | | | | | | | | QUICKSTART (434 lines): 6-step guide tested against live https://meshbay.org — demo accounts alice_test/bob_test, real transfer of README.txt (23ms) and 1MB chunk (275ms recv, 2.4ms decrypt), exact Python commands with measured output. USERGUIDE (785 lines): 11-section reference — architecture, account management, group/node config, file sharing, HLS streaming, security model, moderation/CSAM, troubleshooting, full API table. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
* docs: add HTTPS.md + configure www.meshbay.org redirectChristophe Besson2026-08-091-0/+138
| | | | | | | | | Caddyfile updated: www → 301 → meshbay.org (canonical). Caddy auto-issued Let's Encrypt cert for www.meshbay.org in 4s. HTTPS.md explains the setup, cert lifecycle (90-day, auto-renewed), why 1-year certs are not recommended, DNS requirements. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
* docs: add architecture draft v3 with POC findingsChristophe Besson2026-08-091-0/+804
| | | | | | | | | | | | | Key corrections from spikes 1-6: - JWT jti now required (prevents replay, enables revocation) - Argon2id params updated to target 500ms (256MB memory) - NAT order corrected: STUN before UPnP (UPnP unreliable on SFR) - Transport: TCP+TLS v1, QUIC v2 - GEK wrapping protocol confirmed (ECIES-like, 48B opaque bundle) - Hub API table complete with Spike 6 endpoints - 3-package monorepo structure documented Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
* chore: initialize monorepo structure for MeshBayChristophe Besson2026-08-096-0/+3183
3-package layout: meshbay-common (shared crypto/protocol), meshbay-hub (FastAPI server), meshbay-node (local daemon). Includes validated POC spikes 1-6 in poc/, architecture drafts v1/v2 in docs/, and CLAUDE.md project conventions. All cryptographic primitives extracted from POC into meshbay_common/crypto.py (GEK wrap/unwrap, chunk key derivation, keystore encryption, chunk signing).
