Publish owning data-directory snapshots under a mutex and route bootstrap
and fallback publications through the same synchronization boundary.
Keep polling completion locked through its final notification so shutdown
cannot destroy the condition variable while the notifier still uses it.
Exercise both publication windows with deterministic event-based tests and
use the repository thread-compatibility wrapper.
Preserve Failed in status rendering instead of reporting initialization.
Reanchor the existing metrics environment-read entry; add no exceptions.
This does not close the separate queued-collector and embedding-borrower
lifetime audits or establish universal bounded callback shutdown.

The retired symbol stage never activates, so tuning.post_ingest.
symbol_concurrent and YAMS_POST_SYMBOL_CONCURRENT had no effect, and
status reported symbol_* queue metrics and post_symbol_limit that were
always zero. Remove the config key and environment override, the status
keys and CLI rows, the metrics snapshot fields, and the event-bus symbol
counters. The internal stage slot stays so budget and limiter indices
are unchanged; benchmark JSON keeps its symbol fields at zero.
