+
+## Pull request overview
+
+Adds a preserved research note for the KHALEESI (USENIX Security ’22) prior-art and files a low-priority backlog item (B-0923) that frames it as a future “Kleisli-severance” substrate target within the broader framework vocabulary.
+
+**Changes:**
+- Added a `references/notes/` research note summarizing the paper and mapping it onto existing substrate concepts.
+- Added a new P3 backlog row `B-0923` capturing a very-low-priority future work target.
+- Updated the generated `docs/BACKLOG.md` index to include `B-0923`.

+### Thread 1: references/notes/khaleesi-breaker-of-tracking-request-chains-usenix-22-iqbal-wolfe-nguyen-englehardt-shafiq.md:9 (unresolved)
+
+**@copilot-pull-request-reviewer** (2026-05-28T16:30:17Z):
+
+The reference to `dep-pin-search-first-authority` is ambiguous/inaccurate as written: the actual rule file in-tree is `.claude/rules/dep-pin-search-first-authority.md`. Using the full path (or at least the `.md` filename) makes the cross-reference clickable/searchable and avoids drifting to a non-existent identifier.
+
+### Thread 2: docs/backlog/P3/B-0923-kleisli-severance-substrate-engineering-target-apply-framework-kleisli-substrate-to-privacy-defense-scope-composes-with-khaleesi-prior-art-aaron-2026-05-28.md:64 (unresolved)
+
+**@copilot-pull-request-reviewer** (2026-05-28T16:30:17Z):
+
+These references name rules without the `.md` filename or `.claude/rules/…` path (e.g., `m-acc-multi-oracle-end-user-moral-invariants`). Since the authoritative rule is `.claude/rules/m-acc-multi-oracle-end-user-moral-invariants.md`, using the full path reduces ambiguity and improves navigation/grep consistency across backlog rows.
+
+### Thread 3: docs/backlog/P3/B-0923-kleisli-severance-substrate-engineering-target-apply-framework-kleisli-substrate-to-privacy-defense-scope-composes-with-khaleesi-prior-art-aaron-2026-05-28.md:77 (unresolved)
+
+**@copilot-pull-request-reviewer** (2026-05-28T16:30:18Z):
+
+The reference to `honor-those-that-came-before` is written without the actual rule filename/path; the in-tree rule is `.claude/rules/honor-those-that-came-before.md`. Using the concrete path prevents cross-reference drift and makes it easier to follow from the backlog item.
