Construct a RuntimeContext

Description

Captures reproducibility and backend settings. A context stored on an Engine configures direct Engine$run() calls. When supplied explicitly to run_cohort(), it configures the cohort and takes precedence over scalar seed/backend/worker controls; its replicate_id must be NULL because cohort replication is identified by sim_id.

Usage

RuntimeContext(
  seed = NULL,
  replicate_id = NULL,
  backend = "none",
  n_workers = NULL
)

Arguments

`seed`	Optional integer scalar; top-level seed. NULL = unseeded.
`replicate_id`	Optional integer scalar; stochastic replicate index for a direct Engine run. Cohorts use `sim_id` and reject a non-`NULL` value on an explicitly supplied RuntimeContext.
`backend`	Character scalar; one of `"none"` (default), `"cluster"`, `"mclapply"`, `"future"`.
`n_workers`	Optional integer; number of parallel workers.

Details

The public reproducibility contract is: seed + draw_id + replicate_id + entity_id = deterministic output. Internal stream allocation (stream_id) is set by the run harness and must not be set by users directly.
