Declare logical Evidence sources once and resolve exact retained inputs through
shared application workflows across 20 composition tools. Preserve domain-owned
authentication, source closure, caller choices, coverage and resource admission.
Validation includes public CLI/MCP regressions, local Codex terra/high trials
and fresh-import real-artifact workflows. Measurements, failed attempts and
coverage limits are recorded in docs/verification/evidence-input-composition-2026-10-31.md.

Select completed source-to-bundle mappings and candidates through the shared view owner, preserve reference-file provenance, and retain full Evidence. Reuse bounded JSON reading, heap admission, and cancellation before session writes.
Verified public Redux Toolkit source/map facts with an independent oracle, equivalent CLI/MCP workflows, focused negative controls, and complete CI/review. Historical paired SDK context estimates fall about 64%; timing/resource tradeoffs and final verification receipts are recorded without a general speedup or actual model-token claim.
Fixes#6112.
