+## Algorithmic Audit Scope
+
+Audited worktree: `d898cb1`, with production code at the reviewed implementation
+revision above. This follow-up used source inspection and graph caller traces,
+not benchmarks or new runtime measurements. It covered acquisition and import
+bookkeeping, scope scheduling and projection, filesystem context handoffs,
+inheritance preparation/combination/finalization, and reflective projection and
+schema construction.
+
+Findings 2–3 are retained inefficiencies in paths carried through the refactor,
+not algorithmic regressions introduced by the consolidation. They warrant
+focused follow-up without changing the selected configuration model. The audit
+did not identify an additional correctness defect. Finding 1 remains open.
+
+The selected stable Kahn scheduler, deterministic sorting, composition rules,
+scope boundaries, and required ownership copies are not reconsidered here.
+Previously deferred experiments in [future.md](future.md#3-performance-experiments)
+and the [clone review](future.md#4-clone-traversal-review) retain their separate
+disposition. These findings do not establish new public complexity guarantees,
+input restrictions, performance thresholds, or release gates.
+
+## 2. Avoid Searching All Sources For Each Empty Import Selection
+
+Status: open. Priority: low. Category: algorithmic efficiency.
+
+**Evidence.** `walkDeclarations` calls `recordEmptyImportSelection` for each
+optional declaration that admits no source. In
+[import_acquisition.go](../../internal/engine/import_acquisition.go), lines
+289–300, the latter finds the declaring source by scanning `s.sources` from the
+beginning, even though traversal already knows which source owns the declaration.
+
+**Complexity.** With S acquired sources and D empty declarations, source lookup
+takes O(S × D) comparisons in the worst case, excluding path-copying and source
+selection itself. A broad main import of N constant-size fragments, each with
+one empty optional declaration, visits source positions 1 through N: the sum of
+lookup work is Θ(N²), despite linear source and selection-evidence volume and
+constant import depth. Existing input budgets bound the workload but do not
+remove this avoidable scaling within those budgets.
+
+**Potential refactoring.** Carry the declaring source's integer index through
+the declaration traversal, or maintain a traversal-local source-ID-to-index map.
+Either approach makes each evidence-owner lookup O(1), with O(S + D) total
+bookkeeping for the map alternative. Keep source order and IDs unchanged. Use
+indices rather than retained pointers into the appendable source slice, and
+preserve optional-missing rollback and failed-source retention if maintaining
+an index across admission.
+
+**Verification.** Reuse the source-local/detached empty-selection and partial
+failure coverage in [import_evidence_test.go](../../internal/engine/import_evidence_test.go).
+A broad-fragment behavioral case is useful if existing coverage does not protect
+the chosen index handoff. Verify the removed scan by source review rather than
+adding timing thresholds or assertions about private lookup counts.
+
+## 3. Restrict Import-Scope Edge Preparation To Relevant Nodes
+
+Status: open. Priority: medium. Category: algorithmic efficiency and allocation
+scaling.
+
+**Evidence.** `scheduleAcquisitionScopes` in
+[imports.go](../../internal/engine/imports.go), lines 57–64, recursively schedules
+the outer scope and every pending item-local scope using the same complete
+inclusion graph. `scheduleContributionSlots` in
+[import_graph.go](../../internal/engine/import_graph.go), lines 185–213, constructs
+a local identity-to-slot map but then scans every graph edge and allocates an
+edge slice with capacity `len(graph.edges)` for each scope with at least two
+eligible contributions. Most edges need not touch that scope.
+
+**Complexity.** For Q such scopes and E inclusion edges, preparing the scheduler
+inputs takes O(Q × E) edge inspections and requests O(Q × E) edge-slice capacity
+over the operation. This is cumulative allocation demand, not a claim that all
+those slices remain live together. For N sibling item imports, each with one
+distinct mapping helper, Q and E are both Θ(N), making this preparation Θ(N²)
+even at constant nesting depth. The selected scheduler itself is not the
+problem: each small item-local graph has constant size, and the outer graph
+requires its normal deterministic scheduling work.
+
+**Potential refactoring.** Build a traversal-local adjacency index once after
+acquisition, then gather edges for a scope by its participating source identities
+and retain only edges whose endpoints both have local slots. Alternatively,
+partition the existing edges by their applicable scopes once. Preserve the
+current endpoint-membership rule, item-boundary representation, slot placement,
+group scheduling, and stable Kahn tie-breaking. For the broad sibling family,
+this reduces edge preparation to O(E + P), where P is the total number of local
+slots, followed by the unchanged scheduler cost. Keep this an indexing change
+around the agreed scheduler, not a different ordering algorithm or a cross-load
+cache.
+
+**Verification.** Reuse item/helper interleaving and grouped import scheduling
+coverage in [imports_test.go](../../internal/engine/imports_test.go) and
+[load_request_test.go](../../internal/engine/load_request_test.go), together with
+existing destination/provenance evidence tests. Cover broad independent item
+scopes if a consequential gap remains; verify index construction and edge
+visitation bounds by source review without new performance gates.
