From 20a0de2fe23b9eb2696acedd20300c345e97ce4e Mon Sep 17 00:00:00 2001 From: 1395490241lhj-code <1395490241lhj-code@users.noreply.github.com> Date: Tue, 20 Oct 2026 19:41:51 -0400 Subject: [PATCH 1/2] fix(server): improve Kitchen AI upstream failure diagnostics /api/ai-conversation logged every provider failure as provider_unavailable and dropped the upstream error, so 429, 413, timeouts and 5xx could not be told apart in production logs. - ai_conversation_failed and ai_conversation_completed now carry the safe classification: primaryProvider, timeoutMs, requestSizeBytes, and, on failure, upstream status, reason, timeoutSource and upstreamRequestId; a provider switch records the first provider's fallbackReason. - Field values are validated, not just field names: status must be an integer 100-599, codes must be short safe identifiers (otherwise "unrecognized"), request ids must be 8-128 safe characters (otherwise dropped). Upstream error text, keys and conversation content are never logged. This adds diagnostics only. It does not change provider routing, timeouts, fallback or retries, and it does not identify the production failure; that needs the redacted logs after deploy.

charset=UTF-8 Content-Transfer-Encoding: 8bit On device, a meal follow-up got prose instead of recipe cards, failed retries stacked identical error rows, and the transcript pulled a reader back to the bottom on every streamed delta. - Meal follow-ups: a whole short follow-up (换一个 / 今晚做什么 / 还有别的吗 / 推荐点简单的 / Anything else?) inherits the meal intent when one of the last three user questions was an explicit meal question. Home only. Excluding inventory still withholds the shortlist. Sentences that only share a word (我想换手机 / 推荐电影院 / 今晚做什么运动) read only tonight's plan. - Instructions: dish recommendations use present_recipe_card, cite recipeID and keep prose to one or two sentences, without claiming freshness or quantity. The length rule applies only to recommendations; plan changes and other questions are answered in full. - Transcript: an older attempt of a retried turn that carried only an error (or was stopped empty) is hidden once a newer attempt exists. Presentation only; history is unchanged and partial content always stays. - Auto-scroll (AIConversationAutoScroll): one trigger, at most one scroll per update. A drag up to reread stops following; a drag that dismisses the keyboard keeps the previous state. A new user message, a running retry or a different conversation resumes following, without relying on observing .preparingContext. No animation added. - Tests: assembler privacy negatives assert the actual reads; test47 covers scrolling up mid-stream and sending with the keyboard up, with a DEBUG-only incremental stream script. The structured-blocks AXXXL helper now scrolls both ways (that Light AXXXL red also reproduces on bcca20a). No change to the six content blocks, five proposals, coordinator, persistence, confirmation or undo.
