First read and apply `references/chiefos-runtime.md`. Choose the source method below that matches the requested outcome and available evidence; do not execute every alternate provider path.
tradermonty: manifoldbt-backtester
Load `references/tradermonty/manifoldbt-backtester/SKILL.md` for the complete method, required inputs, ordered decisions, and output contract. Resolve its local resources beneath the same directory.
agiprolabs: backtrader
Load `references/agiprolabs/backtrader/SKILL.md` for the complete method, required inputs, ordered decisions, and output contract. Resolve its local resources beneath the same directory.
agiprolabs: vectorbt
Load `references/agiprolabs/vectorbt/SKILL.md` for the complete method, required inputs, ordered decisions, and output contract. Resolve its local resources beneath the same directory.
Alternate source routing
Additional methods: backtrader, vectorbt. Use the applicable source for its provider and output, retaining the same canonical ChiefOS identity. For a source-specific request, load that source method before answering.
For upstream sibling names, resolve the canonical skill and source entrypoint with `references/source-routing.json`. Load sibling resources from that canonical skill; do not assume the original directory name is independently installed.
