From d91e4dba6eccebf0b14e4459ac7a6f4032110294 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 30 Sep 2026 17:38:58 +0000 Subject: [PATCH 01/10] Vary service mission answer order, resume code labs, surface the observation limit Service-case missions now render prediction/transfer choices and fixes in a deterministic per-mission order; stored indices still point at the source arrays so saved progress keeps its grading. Code-understanding labs reopen on the first step still missing evidence, and the mission practice panel shows a visible notice when the 80-action observation limit is reached.

It now uses guide:global:hour/day. When the provider call fails and the basic guide is shown, the personal daily windows are refunded via a new StoreQueries.refundLimits; burst, network and service windows still count the attempt. The guide prompt now states the real generation allowance from ai-access (guest 2, member 6 per day) and its version is bumped.

keep the last good detail when a refetch fails and clear a selection that no longer exists. - Show pending background analyses in the form with progress and cancel, block a second analysis meanwhile and open the result when it ends. - Show the stored failure reason when background analysis fails. - Open revisions without adding them to the history list or clearing the new-project draft, and link revisions from the root views. - Use one client cleanup helper after deleting a project on either page. - Show the review credit cost on the code dialogue button.
