A half-join tactic yielded each output container with a single time, so the driver could pick one capability for it, and tactics split their output by capability. Timely stamps messages with capability sets, so the driver now ships every container stamped with the unit's capabilities, which cover every update it released. HalfJoinTactic::prep yields containers only. The cursor tactic keeps one builder instead of one per capability. The corgi tactic drops its per-row capability search and the gather that split each block by capability, and ships the projected block whole. Replaces TimelyDataflow#947's one-capability special case. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019XsakwFGwtESwZ1gSYwG4o

Replaces #947.
HalfJoinTactic::prepyielded each output container with a single time, so that the driver could pick one capability for it, and tactics split their output by capability to make that possible. Timely stamps messages with capability sets, so the driver now ships every container stamped with the unit'sCapabilitySet, which covers every update the unit released.prepyields containers only, as DD'sJoinTactic::prepalready does.lower.Net −31 lines (+48/−79).
Triangles delta query (1M edges, mini-02, five alternating runs, medians; counts match):
#954 is neutral on this benchmark, so the load change is this PR's. The 1-worker churn spreads overlap.
Rebased onto #954; the second commit updates #954's collision test to the container-only interface (
