Marc-André Bombeck e31c66e959 fix(security): scrub wide events at the builder, encrypt the replay cache
Three leaks of the same class - data leaving the process unprotected.

addMeta and addExternalCall wrote their values verbatim while setError
and setHttp scrubbed, so the builder's redaction contract held for two
entry points out of four. The finished event is serialised whole to
stdout and the log store, which made meta a trusted sink by accident: a
Telegram request timeout put the bot token there, and the AI provider
chain fed upstream error bodies through it. Both now scrub, at any depth.

Scrubbing cannot help with the second half. A gateway that echoes the
request it rejected echoes the prompt, and on that path the prompt
carries the health snapshot; no pattern separates that from any other
text. Upstream bodies are therefore classified rather than quoted - the
diagnostic question is which rejection occurred and whether it repeats,
which a classification answers without the content.

The idempotency replay cache stored response bodies unencrypted. The
create paths echo their own decrypted payload, so cycle notes, mood text
and allergy reactions sat in cleartext for 24 hours in a column that
lands in every backup; the existing guard missed it because it matches
secret shapes and health data is not secret-shaped. Bodies are encrypted
now, and when encryption is unavailable the response is not cached at
all rather than written in the clear.

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). See api/README.md for the preview commands. Also home to the MCP-server contract: api/mcp-capabilities.md (tools, resources, prompts, write model) and api/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 on docs.healthlog.dev. Includes self-hosting/mcp.md — enabling the off-by-default MCP connector and pointing Claude.ai / ChatGPT / Claude Desktop at it, and self-hosting/sso.md — OIDC SSO login: IdP setup, the identity-pinning security model, OIDC_ONLY consequences, and the break-glass runbook.
  • 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.
