From 1d4bd828a5409033351dab96f4c8bbf1263bfab4 Mon Sep 17 00:00:00 2001 From: Richmond Glenn Viloria Date: Fri, 10 Jul 2026 20:04:49 +0800 Subject: [PATCH 01/21] fix: reject unsafe/injection-prone names in property and meter-group DTOs A property or meter-group name containing quotes could destabilize the chatbot's tool-call generation (a malformed name broke Groq's function-call parsing and surfaced as a 502). Names are also echoed verbatim into chatbot tool-result context, so a semantically injection-like name (no unsafe characters required) could poison the model's context. Add isSafeName and isSafeAgainstPromptInjection validators, the latter reusing chatbot.guard's phrase list as a single source of truth.

No fallback: OCR endpoints 404 until a vision provider is configured. SSRF-guarded image fetching and prompt/response parsing were extracted verbatim into image-fetch.util.ts and ocr-parsing.util.ts so behavior is unchanged. All three OCR call sites (image-extraction, reading, bills, billing-cycle controllers) now thread userId through to resolve the caller's vision config. Also fixes billing-cycle's OCR endpoint returning a different raw_amount than the other two OCR endpoints — it was recomputing rate * consumption instead of passing through the OCR-extracted total, which is wrong whenever a bill has taxes or fixed charges. Removes the now-unused @google/generative-ai dependency.

Adds vision_provider/vision_model/encrypted_vision_api_key fields alongside the existing chat fields, plus PATCH /llm-config/vision to manage them. When the vision provider matches the stored chat provider, apiKey is optional and the chat API key is reused; when it differs, apiKey is required (first setup, or switching to yet another distinct provider). Switching the vision provider back to match chat clears any previously stored distinct vision key via FieldValue.delete() — plain `undefined` would silently no-op given this project's Firestore ignoreUndefinedProperties setting. GET /llm-config now returns both configs: {provider, model, hasKey, visionProvider, visionModel, visionHasKey}.

From cd9fffe4af509cae6e6ee610572d279e6db7edf1 Mon Sep 17 00:00:00 2001 From: Richmond Glenn Viloria Date: Sat, 11 Jul 2026 19:41:18 +0800 Subject: [PATCH 16/21] feat(api): add archive-then-purge hard-delete lifecycle for all entities Adds a second, irreversible DELETE /:id/purge step (admin-only) on top of the existing soft-delete, so right-to-erasure requests can be fulfilled without leaving orphaned child records. Cascades purge to already-archived children the same way the existing archive cascade works.
