Render a small JPEG preview for each stored document and show it at the card's leading edge, falling back to the kind icon when none exists. - Generate previews in the background on upload (new document-thumbnail pg-boss queue) plus a boot-time corpus backfill for existing documents; upload never blocks on or fails because of it. Images are downscaled via @napi-rs/canvas, a PDF's first page is rasterised then downscaled, every other type is skipped. Generation never throws. - Store the preview encrypted at rest in a 1:1 DocumentThumbnail side table (migration 0236) so the list/detail queries that omit the original blob never drag the preview either. Same AES-256-GCM string codec + fail-closed decrypt as the content index; wired into the key-rotation walk. - Serve it through an owner-scoped GET /api/documents/inbound/[id]/thumbnail (auth + module gate + userId-scoped query + fail-closed decrypt), always image/jpeg + nosniff + private, no-store; 404 on miss. The card renders an authed lazy <img>, onError falls back to the icon. - Add hasThumbnail to the document DTO so the card only fetches a preview that exists. Also drop the "search looks inside your documents" caption from the overview (the index-all prompt stays) and the per-card searchable marker; both were noise. Remove the now-unused i18n keys across all six locales.
docs/ — internal reference + operator playbooks
The user-facing documentation lives at https://docs.healthlog.dev — that's the canonical surface for self-hosting guides, integration walkthroughs, AI-provider setup, and the doctor-report workflow.
The files in this directory are the internal operator playbooks, audit notes, and machine-readable specs that ship alongside the source:
api/— the OpenAPI 3.1 spec for the native-client subset (iOS DTO codegen target). Seeapi/README.mdfor the preview commands. Also home to the MCP-server contract:api/mcp-capabilities.md(tools, resources, prompts, write model) andapi/mcp-skills.md(building a connector / skill).ops/— backup / restore + encryption-key-rotation playbooks. These are the runbooks an operator reaches for during an incident.self-hosting/— horizontal-scaling notes (HEALTHLOG_PROCESS_TYPE=web|worker|all) and the deploy-pipeline recipe. Routine install steps stay ondocs.healthlog.dev. Includesself-hosting/mcp.md— enabling the off-by-default MCP connector and pointing Claude.ai / ChatGPT / Claude Desktop at it.migration/— release-by-release migration notes. Read the entry for the version you're upgrading from.audit/— per-release audit summaries archived for forensic traceability.apple-store-connect-checklist.md— the iOS submission gate.doctor-report.md— PDF generator design notes.codex-protocol-spec.md— Codex / ChatGPT OAuth protocol reverse-engineering notes.ui-guidelines.md— UI / a11y house style.
