- ChainRule._expandRuleFromSrc now expands tuple_to_userset configs: from a
source node the reachable set is the objects sharing an intermediate with
the source (src ->computed-> intermediate ->tupleset-> object, direction
aware, weakest-link combined). Lets a TTU evidence serve as an intermediate
condition step in a chain.
- scripts/benchmark.js: ratio-based self-calibration. Comparing each action's
RATIO to a cheap reference action (default check[direct-hit]) cancels
machine-load swings that scale all actions proportionally, so the gate only
fails on code regressions that shift a single action's ratio. The reference
is still checked absolutely with a loose bound. Verified: stable across
runs, and a simulated union-ttu slowdown is caught (+76.8% ratio).
Tests: chain-condition-step intermediate TTU expansion.
