test(memory-core): exercise fuzzy-window straddle path for #80613

MilosM348 · cursoragent · MilosM348 · commit 076631907c52 · 2026-05-11T13:13:35.000-04:00
Address ClawSweeper P3 on PR #80702: the existing integration test recorded the recall snippet at the exact human bullet line, so relocateCandidateRange always took the exact-match path and never exercised the fuzzy window search that originally latched onto the managed-block straddle window in #80613. Add a regression that records a clean-leading multi-line straddle snippet at a stale 20..30 range, forcing rehydration through the fuzzy window search. Verified the new test FAILS without redactManagedDreaming Lines (MEMORY.md receives '- - Plan switches use exRule, not abConfig ## Light Sleep  - Candidate: ... - status: staged ' verbatim) and PASSES with the sanitizer in place. All 88 tests across short-term-promotion and dreaming-phases pass. Co-authored-by: Cursor <cursoragent@cursor.com>
