From 67e416c6d9b59327f2d3bfa801ed52aaad6a703f Mon Sep 17 00:00:00 2001 From: Daniel Date: Sat, 12 Sep 2026 04:57:35 +0200 Subject: [PATCH] docs: merge the duplicate pairs and correct them against the running app Three pairs of docs described the same thing twice, and the copies had drifted apart. Merged each into one file, keeping the unique content from both: - ARCHITECTURE.md -> architecture.md (its operational map: ownership, request flow, runtime boundaries, source of truth, deployment shape) - DEVELOPMENT.md -> developer-guide.md (change workflow, Clinical Assistant high-risk areas, frontend rendering rules, deployment checks) - transcription-options.md -> speech.md (the clinic setup table, and the list of browser-Whisper paths that must stay removed) Then audited what remained against the code and the live database rather than against the previous docs. Corrected: - Google Vertex was still documented as a provider across nine files. The SDK is gone; AI_PROVIDER=vertex now logs an advisory and falls back to OpenRouter, and Gemini is reached through LiteLLM. Fixed the provider selection order to match src/utils/ai.js, which starts from LITELLM_API_BASE. - promptSafe was documented on 8 routes; it is on 13. - Node 20 -> 24, "24 vanilla JS modules" -> no fixed count, and transcribe.js/tts.js -> sttProvider.js/ttsProvider.js, which is what exists. - STT/TTS are LiteLLM-only; README listed direct Google, AWS Transcribe and ElevenLabs paths that are not in the runtime. - Learning Hub PPTX export was documented as pptxgenjs, which is not a dependency. It is pandoc against a reference deck. - POST /api/admin/milestones/seed does not exist; it is /bulk-import. - NEXTCLOUD_URL and NTFY_TOPIC are not read anywhere. Nextcloud is per-user in the users table, and the ntfy topic is derived as pedscribe-{userId}. - A prose paragraph sat inside the Clinical Assistant settings table, so half the rows rendered as text. Filled the gaps the audit exposed: - database.md was missing 12 of 29 tables, including user_resources, personal_notes, login_codes, registration_invites and generated_image_jobs. - developer-guide.md was missing 11 routers and 10 frontend modules. - api-reference.md detailed 121 of 244 endpoints and said so, but whole features were absent. Added an endpoint index covering Clinical Assistant, My Resources, Notes, Diagrams, ED Encounters, invites and sign-in codes. - configuration.md was missing METRICS_TOKEN, REDIS_URL, API_RATE_LIMIT_MAX, the LITELLM_* model variables, the DB_* ones maintenance.js reads, and the per-purpose S3 resolution scheme. - clinical-assistant.md documented 2 of its 17 environment variables. - features-explained.md had no entry for My Resources or Clinical Assistant. Renamed the three remaining SHOUTING filenames to kebab-case, which is what the docs viewer's prettyName() was working around, and rewrote README's index, which listed architecture.md twice and omitted nine files. Noted but not changed: the Turnstile site key is hardcoded in index.html rather than read from TURNSTILE_SITE_KEY, and /api/health/detailed can report tts: 'elevenlabs' though no ElevenLabs path exists.
