Task A10

Task Selected

• Chose A10 — Swift Duplication Detection per Phase A priority (automation track after A8) and absence of blockers; PRD at DOCS/AI/github-workflows/02_swift_duplication_guard/prd.md confirms readiness.

Deliverables

• New in-progress spec DOCS/INPROGRESS/A10_Swift_Duplication_Detection.md:1 captures objective, context, criteria, and implementation notes referencing the PRD/workplan.
• Updated queue DOCS/INPROGRESS/next_tasks.md:27 now marks A10 as “In Progress” and links to the new PRD stub so no other agent reselects it.

Implementation A10

Add Swift-only duplication gate, share test reader, and wire pre-push hook

• Scope run_swift_duplication_check.sh to Swift-only globs, consolidate ignores, and keep the Node 20/25 jscpd wrapper as the single entrypoint for CI/local runs.
• Deduplicate InMemoryRandomAccessReader into Sources/ISOInspectorKit/TestSupport/, removing the two identical test copies.
• Run the duplication gate in .githooks/pre-push, emitting reports under Documentation/Quality/.
• Refresh A10 docs/todo status to reflect the pre-push gate and local verification.

Verification

REPORT_PATH=/tmp/swift-duplication-report.txt ./scripts/run_swift_duplication_check.sh (local, Node 25.2.1) → 0% duplication.
