Robust ignore rules for 'Stu Health Data/', PHI file types, and /private/ so real health data and credentials can never be staged in this public repo. Verified via git check-ignore + git add -A --dry-run. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NsEPAr9R7jXAJcEYFN4acb
PersistentVaultStore (redb-backed) seals ProvRecords with XChaCha20- Poly1305 so they survive a restart. CredentialVault derives a key from a master passphrase via Argon2id and seals per-source logins; wrong passphrase is rejected, Debug is redacted. Both behind a non-default 'persist' feature so default/WASM builds stay redb/argon2-free. Proven: round-trip across reopen, wrong-key/tamper reject, zero plaintext on disk; cargo test + clippy -D warnings green.

Helix-Build-Spec.md (onboarding + proactive analyst delivery plan); product spec figures numbered with captions + cross-refs; ADR-045..049 (credential vault, agentic-browser acquisition, single-tenant local-first topology, AIMDS guardrails, scheduled per-source pulls).

New helix-demo crate: a deterministic generator for the fictional persona 'Alex Rivera' (clearly labeled SAMPLE) with 2,650 records + 3 meds + 2 clinician notes across Apple Watch, Lose It, RENPHO (~50-metric panel), Quest labs, pharmacy, and EMR -- one coherent, grounded story (mild iron deficiency + sleep + improving body-comp + borderline lipids; no false alarms). Wired into the UI (ui/demo-dossier.json) so the app boots a rich dossier through the REAL pipeline. cargo test -p helix-demo 13 passed; workspace green; clippy clean; verified live in headless Chrome. Stacks on #1; diff reduces to just the demo once #1 merges.

Summary
Adds a complete synthetic demo dossier so anyone cloning the repo sees the full Helix experience end-to-end — no real data required.

helix-democrate: a deterministic generator for a fictional persona ('Alex Rivera', clearly labeled SAMPLE) with 2,650 records + 3 meds + 2 clinician notes across all six domains (Apple Watch, Lose It, RENPHO ~50-metric panel, Quest labs, pharmacy, EMR), telling one coherent, grounded story (mild iron deficiency + sleep + improving body-comp + borderline lipids — no false alarms).Wired into the UI (
ui/demo-dossier.json) so the app boots this rich dossier through the real pipeline — grounded/cited answers, a decomposable score, bio-age, focus areas.Proof:
cargo test -p helix-demo13 passed ·cargo test --workspacegreen · clippy clean · verified live in headless Chrome.Everything is labeled SAMPLE / SYNTHETIC — not a real person.
