An independent reviewer broke the quarantine rule twice by running it. In a two-atom library, a second source repeating the claim word for word could not vouch for it; 40 unrelated memories could. The old rule handed the choice of words to rare_terms, which drops words common to the corpus, so the corpus size and the attack's own words decided whether a stranger was believed. Corroboration now demands the claim's three longest words, with the instruction phrases stripped out, ANDed by the new text_index.fts_all_expression. Neither the library's size nor the attack can flip it, and both cases are tests. Also from that review: - A question is a read. The DF cache no longer remembers a word the corpus has never used, so an unauthenticated search cannot grow the store one row per novel word. "A question is not a write" was false for /api/search and /api/ask. - The prompt now states that packed evidence is quoted material, not an instruction: once a quarantined sentence is corroborated it does reach the model. - ForgetReport's semantic_cache_cleared reached the frontend as well as Go. - runtime.py: process_vision_info returns a third element only when return_video_kwargs is set, and this call does not set it, so the unpack takes the first two. Two pre-existing pyright errors go, behaviour is unchanged. CHECKLIST corrected against measurement: 13 renamed lines rather than 11, and 10 English / 9 Chinese injection signals rather than 11 / 8. Gates: pytest 312 passed, ruff clean, mypy 24 errors in 9 files (net zero), pyright 0 errors on the five touched files, npm build and eslint clean, scripts/mcp_write_smoke.sh PASS.
