 - Implementation complete: grid stretches both top cards to the same row height, including creation forms and document rows; narrow cards retain independent vertical flow. The entire right help disclosure and two requested selection paragraphs are removed, while the actual full-selection limit message remains conditional. Imported current 2cc product/test/README state has no knowledge conflict; independent review confirms Main/shared/resources/package identical to 7c.
 - Verification: 6 knowledge/page/guidance/workflow unit files / 100 tests, 5 headless scenarios at 375/768/1024/1440, typecheck/full build/scoped 21-file ESLint and whitespace checks passed. Geometry assertions include empty, expanded creation and ready-document equal heights; root inspected the desktop screenshot. All 66 non-Renderer artifacts are byte-identical to immutable Main snapshot.
 - Fresh stage knowledge-align-20261013-ec03b792 reuses prior guards with default input-discard authorization false, unique marker/temp names and fresh predecessor binding. It recognizes implicit fieldset knowledge groups, checks equal heights and removed copy, and restores an originally selected Advanced tab without changing any field. Saved configuration TEXTAREA values are excluded from unsent-input detection only when the visible fixed saved indicator and inactive beforeunload prove the configuration is saved; new creation/chat inputs and all real pending/dirty/interaction protections remain.
+- Source committed as 2899009215b1de8e28b84fc108e880c6e68a6098, with product delta against current 2cc limited to CloudKnowledge, CloudKnowledgeSelector and agent-config.css. Fresh prepare/verify passed with strict predecessor and Main byte proofs. First activation held because new unsaved configuration/input and beforeunload were true, no background lease or trusted interaction; pointer/compat/Main were unchanged and the task marker/Inspector were cleaned up.
+- User explicitly answered this fresh decision 「清除当前修改并刷新」. Root then invoked the existing one-run discard flag; activation succeeded and current Renderer/effective source is 2899009 over unchanged Main7c / PID9968 / port58003. Actual loaded JS/CSS, stable file URL, original route, profile/login, foreground PID1353 and closed Inspector verified; cleared input was not restored. The original page did not show knowledge after refresh, so no forced Agent navigation occurred; four-width source/fixture screenshots provide the knowledge geometry and copy evidence. Root independently re-ran active-verified proof and receipt/current/manifest consistency. Old snapshots and held audit remain intact; no cloud data changes, main merge/push or cleanup.
