A single instance with a malformed `enable` value (e.g. the typo `enable`
instead of `enabled`/`on`) made every configured notification/audit target
of every type fail to load. `create_targets_from_config_with_store_mode`
collected instance configs through the strict `try_collect_target_configs`,
whose `.collect::<Result<Vec, _>>()` short-circuits on the first error and
drops all siblings; the surrounding `?` then aborted the loop over every
plugin type.
This contradicted the function's own documented contract ("Creation is
fault-isolated per instance") and was inconsistent: target construction
failures were already isolated into the `failures` accumulator, only config
collection failures were fatal.
Add `collect_target_config_results[_from_env]`, which returns the enabled
`(id, config)` pairs plus a per-instance failure summary, and use it in the
create path. Per-instance collection errors now flow into the same
`failures`/`creation_failures` accumulator as construction failures: healthy
siblings and other target types still load, while the malformed instance is
surfaced so the notify lifecycle stays non-converged/retryable and an Admin
write cannot report a false success. Audit likewise keeps logging through
its valid targets instead of going fully Stopped.
Follow-up to #5088.
feat(targets): add an opt-in NATS JetStream publish path for the notify and audit targets
The NATS notify and audit targets publish through NATS Core, which returns
before the server has durably accepted the message. A broker restart or a
connection drop between the publish and the flush loses the event, even though
the send queue has already cleared it, and no acknowledgement gates that clear.
An opt-in JetStream publish path clears a queued event only after the server
returns a durable PublishAck, so delivery is at-least-once across a broker
restart or a reconnect. It applies to both the notify and audit NATS targets, is
off by default, and is byte-identical to the NATS Core path when disabled.
The path includes durable store-and-forward, a stable dedup id sent as the
Nats-Msg-Id header so a replayed event is collapsed by the stream duplicate
window, pre-flight stream validation, and a bounded failed-events store for
terminally-failed and retry-exhausted events. Three configuration keys per
target select it: JETSTREAM_ENABLE, JETSTREAM_STREAM_NAME, and
JETSTREAM_ACK_TIMEOUT_SECS, under the RUSTFS_NOTIFY_NATS_ and RUSTFS_AUDIT_NATS_
prefixes.
The on-disk batch filename separator changes from colon to underscore so
batch names are valid on Windows filesystems, with transparent read-back
of files written under the previous separator. The migration affects the
shared queue store for every target type and lands with this feature
because the store gains its first Windows-exercised paths here.

The pulsar config validation rejected any non-`pulsar+ssl` broker whenever
`tls_allow_insecure` was set or `tls_hostname_verification` was disabled.
Both toggles are inert on a plaintext `pulsar://` broker — the Pulsar client
only applies them for `pulsar+ssl` — so treating a non-default value as fatal
is wrong.
This surfaced as issue #4796: the console persists `tls_hostname_verification`
as `false` (the checkbox defaults to unchecked while the server default is
`on`). At creation time the value is not present in the unmerged request and
falls back to the safe default, so the connectivity check passes and the
target comes online. On restart the persisted config is merged and validated,
the `false` is read back, and the target is rejected — permanently offline
even though Pulsar is reachable.
Relax both the loader-side (`validate_pulsar_broker_config`) and runtime-side
(`PulsarArgs::validate`) checks so only a `tls_ca` bundle — real TLS trust
material that is never defaulted to a non-empty value — requires a
`pulsar+ssl` scheme. The inert toggles no longer fail the target. This also
heals configs already persisted with the bad value. Add regression coverage
for both paths.
