Six bugs in parallel = TRUE mode:
1. PSOCK workers (Windows / R < 4.0) never had AMR loaded, so every
exported/AMR function call failed. Added clusterEvalQ(cl, library(AMR))
with a graceful fallback to sequential when the package cannot be loaded
(e.g. dev-only load_all() environments).
2. clusterExport'd AMR_env was a frozen serialised copy; as.sir() on the
worker wrote to AMR:::AMR_env while run_as_sir_column read from the stale
copy, so the captured log was always wrong. Fixed by resolving AMR_env
dynamically via get("AMR_env", envir = asNamespace("AMR")) inside the
worker function, and removing AMR_env from clusterExport.
3. In the fork-based (mclapply) path each worker inherited the parent's full
sir_interpretation_history. Capturing the whole log then combining across
workers duplicated every pre-existing entry. Fixed by recording the log
row count before the as.sir() call and slicing only the new rows
afterwards.
4. run_as_sir_column used non-exported internals (%pm>%, pm_pull,
as.sir.default) that are inaccessible on PSOCK workers after library(AMR).
Replaced pipe chains with direct as.mic(as.character(x[, col, drop=TRUE]))
and as.disk(...) calls, and changed as.sir.default() to as.sir() which
dispatches correctly via S3.
5. With info = TRUE, worker forks printed per-column progress messages
simultaneously, producing garbled interleaved console output. Per-column
messages are now suppressed inside workers (effective_info = FALSE) while
the outer "Running in parallel" / "DONE" messages still appear.
6. Malformed Unicode escape \u00a (3 hex digits) in the "DONE" banner was
parsed by R as U+00AD (soft hyphen) + "ONE"; corrected to .
