96-127: The 500ms timeout for empty-bucket detection may be fragile.The hardcoded 500ms deadline assumes the initial watcher snapshot arrives within that window. On high-latency networks or under load, this could cause the scheduler to start with an incomplete job set, silently missing jobs that arrive after the timeout but before the first

- Making the timeout configurable
- Using the NATS

Inline comments:
In `@rsworkspace/crates/trogon-cron/Dockerfile`:
- Around line 22-31: The runtime Dockerfile currently runs the container as
root; modify the runtime stage to create a dedicated non-root user and group
(e.g., trogon), ensure the copied binary /usr/local/bin/trogon-cron is owned by
that user (chown) and has executable permissions, set a sensible HOME if needed,
and add a USER trogon directive before ENTRYPOINT so the container runs as the
non-root user; reference the runtime stage, the COPY of
/usr/local/bin/trogon-cron, ENTRYPOINT ["trogon-cron"], and CMD ["serve"] when
making these changes.
In `@rsworkspace/crates/trogon-cron/src/client.rs`:
- Around line 73-80: The code in set_enabled uses CronError::Kv(format!(...))
for a missing job; add a typed error variant like CronError::JobNotFound { id:
String } in your error enum (e.g., in error.rs) and replace the ok_or_else
mapping in set_enabled to return CronError::JobNotFound { id: id.to_string() }
instead of constructing a formatted string; update any other sites that
currently create "job not found" Kv strings to use the new JobNotFound variant
so callers can match on the typed error.
In `@rsworkspace/crates/trogon-cron/src/executor.rs`:
- Around line 279-281: The current guard around publish_dead_letter (the if
max_retries > 0 check) prevents publishing a DLQ event when an execution
permanently fails with zero retries; update the failure path so
publish_dead_letter(&publisher, &tick, "publish", actual_attempts,
last_error).await is invoked whenever execution ultimately fails (i.e., when
last_error indicates a terminal failure), regardless of max_retries or retry:
None. Remove or replace the max_retries conditional in the block that handles
final failures (referencing publish_dead_letter, publisher, tick,
actual_attempts, last_error) and make the same change in the analogous block
around lines 442-444 so dead-letter events are always emitted for permanent
failures.
- Around line 224-280: The retry loop is converting errors to String (last_error
= e.to_string()) and losing typed context; instead introduce a small internal
error enum (e.g., PublishError with variants for NatsPublish, Spawn, etc.) and
change last_error from String to that enum (or Option<PublishError>), assign
Err(e) into the appropriate variant when publish_tick fails, and propagate that
typed error through the loop; only convert to String when calling
publish_dead_letter and in the final tracing::error (i.e., stringify inside
publish_dead_letter or right at the logging call). Update publish_dead_letter
(or its callsite) to accept the typed error or perform the to_string there, and
ensure the enum implements Display/Debug/From for the original error types so no
source context is lost.
- Around line 184-201: The concurrent check in RuntimeAction::Spawn uses
state.is_running.load(...) then later sets it, which is racy; replace the
load+separate store with an atomic compare_exchange on state.is_running to
change false -> true (using appropriate Orderings, e.g., SeqCst or
Acquire/Release) and only call spawn_process when compare_exchange succeeds;
apply the same compare_exchange replacement for the other occurrence around
lines 297-303 so the guard for non-concurrent jobs is claimed atomically before
invoking spawn_process.
In `@rsworkspace/crates/trogon-cron/src/nats_impls.rs`:
- Around line 195-218: The TickPublisher::publish_tick implementation is
discarding typed error context by converting PublishOutcome errors to strings;
update the error handling to preserve and wrap the original error types instead
of calling to_string(). Add variants to CronError (e.g.,
CronError::PublishError(PublishError) and CronError::AckError(AckError) or a
single CronError::PublishSource(Box<dyn Error + Send + Sync>)) and map
PublishOutcome::PublishFailed(e), ::AckFailed(e), and ::StoreFailed(e) to those
variants (or use .source() wrapping) when returning Err; ensure publish_tick
(and any call sites of publish_event / JetStreamContextPublisher) return the new
CronError variants so the original PublishError/AckError types and context are
preserved rather than being stringified.
- Around line 36-49: The NatsConfigStore::put_job implementation wraps SDK
errors into CronError::Kv by converting them to strings and uses map_err,
violating the zero-cost passthrough rule; change the implementation of
ConfigStore for NatsConfigStore to return the underlying SDK errors directly
(i.e., remove map_err calls around self.js.get_key_value(...) and kv.put(...)
and avoid converting errors to strings) or adjust CronError::Kv to carry the
original SDK error type so you can use the ? operator without losing context;
ensure serde_json::to_vec errors are propagated similarly (e.g., via ?), so the
body of put_job is a direct await/return passthrough to js.get_key_value and
kv.put with no map_err conversions.
- Around line 234-259: The code in NatsLeaderLock's try_acquire, renew, and
release is converting underlying store errors to strings (map_err(|e|
CronError::Kv(e.to_string()))) which discards original error types; change this
by making CronError::Kv carry the original error (or a boxed dyn Error) and/or
implement From for the store error types, then replace map_err calls with
map_err(Into::into) or map_err(CronError::from) so create/update/delete errors
are preserved; update the CronError enum definition to accept the concrete
source types (or Box<dyn std::error::Error + Send + Sync>) and adjust
try_acquire, renew, and release to forward the original
CreateError/UpdateError/DeleteError instead of to_string.
In `@rsworkspace/crates/trogon-cron/src/scheduler.rs`:
- Around line 180-201: The helper reestablish_config_watch currently blocks
retries and is not cancellation-aware, which can prevent run() from observing
shutdown signals; modify reestablish_config_watch to accept a cancellation
trigger (e.g., a ShutdownReceiver, a CancellationToken, or an async
shutdown_signal future) or return early on cancellation, then inside the loop
use tokio::select! to race ConfigStore::load_and_watch().await and the shutdown
trigger (and the sleep retry against the shutdown), returning an Err/early exit
when cancelled so the outer run() can handle graceful leader-lock release;
alternatively move the retry sleep/select logic up into run() and keep
reestablish_config_watch as a single-attempt helper that returns its
watcher/error to the caller.
- Around line 153-156: preserve_runtime_state currently only copies is_running
and publish_in_flight, causing last_fired to reset and interval jobs to fire
immediately after reload; update preserve_runtime_state (and the build_job_state
path that calls it) to also carry forward the prior firing state by copying
old_state.last_fired into new_state.last_fired when the schedule is unchanged,
or, if the schedule has changed, recompute new_state.last_fired from
old_state.last_fired (e.g., advance/snap it through the new schedule) so reloads
do not treat every reload as a first load; refer to preserve_runtime_state,
build_job_state, and JobState.last_fired to locate where to copy or recompute
the value.

prefix and allows invalid NATS subjects (wildcards, whitespace, empty tokens);
update the constructor to validate the full subject using the existing
trogon-nats token validation (e.g., trogon_nats::token::validate or the SDK
subject wrapper) and return CronError::InvalidJobConfig with a clear reason on
failure; specifically, inside PublishSubject::new replace the simple starts_with
check with a call to the trogon-nats validation function (or construct the
trogon-nats Subject type) for the entire subject string and propagate validation
errors into the same InvalidJobConfig variant so invalid subjects cannot be
constructed.

types (e.g., KvError, PublishError, JobConfigError) or use wrappers carrying the
original error (e.g., Kv(Box<dyn std::error::Error + Send + Sync>),
Publish(Box<dyn std::error::Error + Send + Sync>), InvalidJobConfig { source:

- Around line 279-281: The code only calls publish_dead_letter(&publisher,
&tick, "publish", actual_attempts, last_error).await when max_retries > 0, so
permanent failures with retry: None or max_retries == 0 never get sent to the
DLQ; remove or change the max_retries guard so publish_dead_letter is invoked
whenever execution finishes in a failure path regardless of max_retries (i.e.,
call publish_dead_letter in the failure handling branch that currently handles
terminal errors), and mirror this same fix for the other failure branch that
currently has the same max_retries check (the similar publish_dead_letter call
later in the file).
- Around line 184-201: The check of state.is_running in RuntimeAction::Spawn is
racy because load() followed by spawn_process()’s store(true) allows two threads
to both spawn when concurrent() == false; change the logic in execute() (where
RuntimeAction::Spawn is handled) to attempt an atomic compare_exchange(false,
true, Ordering::SeqCst, Ordering::SeqCst) on state.is_running and only proceed
to call spawn_process if the exchange succeeds, and remove the unconditional
store(true) inside spawn_process(); ensure spawn_process (or its completion
path) still clears is_running back to false when the job finishes or fails, and
apply the same compare_exchange-based claim to the other similar invocation that
currently mirrors this pattern.
- Around line 223-278: The retry loop currently collapses all errors to String
early (last_error = e.to_string()), losing source/context; introduce a small
internal typed error enum/struct (e.g., enum RetryError {
Publish(trogon_nats::Error), Timeout, BackoffExceeded, ... }) and change
last_error from String to Option<RetryError>, store Err variants as last_error =
Some(RetryError::Publish(e)) inside the loop (refer to publisher.publish_tick
and the for attempt loop), keep all context until the DLQ/log boundary, and only
stringify or serialize the error when constructing DeadLetterPayload or when
emitting the final tracing::error/tracing::warn (use %last_error.to_string() or

- Around line 36-120: The current NatsConfigStore implementation for ConfigStore
(methods put_job, get_job, delete_job, list_jobs, load_and_watch) is converting
async-nats/jetstream SDK errors to strings via map_err(|e|
CronError::Kv(e.to_string())), losing typed error context; fix by making these
methods passthrough zero-cost: either change CronError::Kv to hold the original
SDK error type (wrap the error instead of to_string) or update the ConfigStore
signature to use an associated Error type and return the SDK errors directly
(remove map_err and the e.to_string() conversions) so all KV calls
(get_key_value, entry, delete, keys, get, etc.) propagate the concrete SDK
errors via ?.
- Around line 194-215: The publish_tick implementation on jetstream::Context
currently collapses PublishOutcome variants into CronError::Publish(String);
change CronError to preserve source error types (e.g., add variants
CronError::PublishFailed(PublishError), CronError::AckFailed(AckError),
CronError::AckTimedOut(Duration) and CronError::StoreFailed(StoreError) or a
single CronError::Publish{source: PublishOutcomeError} that wraps the original
error), then update publish_tick to map each PublishOutcome variant to the
corresponding typed CronError (use .map_err(|e| CronError::PublishFailed(e)) or
construct the appropriate variant for AckTimedOut with the timeout), ensuring
you propagate the original error values instead of converting them to strings;
touch the publish_tick function, the PublishOutcome match arms, and the
CronError enum to implement this typed error propagation.
- Around line 233-258: The impl for NatsLeaderLock currently converts SDK errors

Error the underlying KV/store error type (the concrete error returned by
self.store.create/update/delete, e.g., crate::kv::Error or the store client's
error type) and remove all map_err/string conversions so each method returns the
store's Result directly (call self.store.create(LEADER_KEY, value).await,
self.store.update(LEADER_KEY, value, revision).await, and
self.store.delete(LEADER_KEY).await without mapping errors). Ensure references

two guarded calls (the one using publish_dead_letter(&publisher, &tick,
"publish", actual_attempts, last_error).await and the duplicate at the later
block) and change the control flow so that whenever a terminal failure path is
taken (use the existing failure context variables: publisher, tick,
actual_attempts, last_error) you await publish_dead_letter(...) unconditionally
instead of only when max_retries > 0.
- Around line 184-201: The non-concurrent guard currently does a separate load()
then later store(true), which allows a race where two ticks both see false and
both spawn; change the logic in the RuntimeAction::Spawn branch to atomically
claim state.is_running using compare_exchange(false, true, Ordering::SeqCst,
Ordering::SeqCst) when !command.concurrent(), and only call spawn_process() if
the compare_exchange succeeds (otherwise log/debug skip). Also remove or adapt
the separate state.is_running.store(true) in the spawn_process / completion path
so that only the atomic claim sets the flag (and ensure the flag is cleared on
process end as before).
In `@rsworkspace/crates/trogon-cron/src/nats_impls.rs`:
- Around line 233-258: The leader-lock methods (NatsLeaderLock::try_acquire,
::renew, ::release) currently map KV errors to CronError::Kv(e.to_string()),
discarding the original typed error and its source chain; change the
CronError::Kv variant to hold the original error type (or a boxed dyn Error) and
map errors directly (e.g., .map_err(|e| CronError::Kv(e)) or .map_err(|e|
CronError::Kv { source: e }) instead of e.to_string()), so the errors returned
from self.store.create/update/delete preserve their concrete type and source.
- Around line 194-215: The TickPublisher impl for jetstream::Context currently
collapses PublishOutcome variants into CronError::Publish(String); instead
preserve and wrap the original typed errors instead of converting to
strings—update CronError to include variants/fields for PublishFailed,
AckFailed, AckTimedOut (with duration), and StoreFailed (or a single Publish
variant that contains the original PublishOutcome::... error type), then change
the matching in publish_tick (which calls publish_event and uses
JetStreamContextPublisher and PublishOutcome) to return
Err(CronError::PublishFailed(e)) / Err(CronError::AckFailed(e)) /
Err(CronError::AckTimedOut(timeout)) / Err(CronError::StoreFailed(e)) (or the
equivalent wrapper) so the original error types are preserved and chainable
instead of using to_string()/format!.
- Around line 36-157: The code currently stringifies SDK errors via map_err(|e|
CronError::Kv(e.to_string())) in NatsConfigStore (see put_job, get_job,
delete_job, list_jobs, load_and_watch), which loses error types; change
CronError::Kv to hold the concrete SDK error type (e.g., kv::Error or the
appropriate JetStream error) or add a new variant wrapping Box<dyn
std::error::Error + Send + Sync>, implement From<kv::Error> for CronError, then
remove the map_err closures and use the ? operator directly (e.g., let kv =
self.js.get_key_value(CONFIG_BUCKET).await?; and similarly for
kv.put(...).await? etc.), so SDK errors are propagated without being
stringified. Ensure any places that previously used CronError::Kv(String) are
updated to handle the new variant.

Nitpick comments:
In `@rsworkspace/crates/trogon-cron/src/config.rs`:
- Around line 7-31: Replace raw primitive fields (expr, subject, bin,
interval_sec, timeout_sec) in the public config enums/structs (Schedule, Action,
and JobConfig) with domain-specific value objects/newtypes that perform
validation at construction and implement Serde (e.g., CronExpr, NatsSubject,
ExecutablePath, PositiveSeconds); update Schedule::Interval to use
PositiveSeconds.interval_sec and Schedule::Cron to use CronExpr.expr, and
Action::Publish/Spawn to use NatsSubject.subject and ExecutablePath.bin, plus
PositiveSeconds.timeout_sec; ensure each newtype exposes a fallible constructor
that enforces invariants and Serde deserializes by invoking that constructor so
malformed configs fail at deserialization rather than later during JobConfig
conversion.
In `@rsworkspace/crates/trogon-cron/src/main.rs`:
- Around line 136-150: Replace the ad-hoc io::Error in cmd_get with the crate's
typed CronError: update/ensure CronError has a NotFound { id: String } (or
similar) variant, then return Err(CronError::NotFound { id: id.to_string()
}.into()) when client.get_job(id).await? yields None; modify the cmd_get
function to construct and return that CronError instead of using format!() so
error handling is consistent with the rest of the crate.

Timezone validation accepts arbitrary non-existent timezone strings
Low Severity
The validate_timezone function only checks for whitespace, control characters, and leading/trailing spaces. Any syntactically clean but semantically invalid timezone string (e.g., "Mars/Base", "Foo/Bar") passes validation. This defers failure to the NATS server at schedule publish time, making it harder to diagnose. Since the cron crate and chrono-tz are already available, the timezone could be validated against the IANA database at spec validation time.

NATS healthcheck tool may be missing in new image
High Severity
The NATS image changed from nats:2.11-alpine (which bundles busybox wget) to synadia/nats-server:nightly (a minimal Alpine image that may not include wget). The healthcheck still uses wget to probe the monitoring endpoint. If wget is unavailable, the healthcheck will permanently fail, and every service with depends_on: nats: condition: service_healthy — including trogon-gateway and trogon-cron — will never start.

Unused time dev-dependency in trogon-cron Cargo.toml
Low Severity
The time = "0.3" crate is listed as a dev-dependency but does not appear to be used in any test files for trogon-cron. The timestamp conversions in the crate use chrono, and while async_nats uses time internally for StreamMessage.time, the time crate is not directly referenced in test code. This is dead dependency clutter.

stream_by_subject returns stream name string comparison issue
Low Severity
The ensure_source_subject method calls self.js.stream_by_subject(source_subject) which according to NATS JetStream API returns the stream name as a String. The comparison source_stream != SCHEDULES_STREAM compares this with the constant "CRON_SCHEDULES". However, if this API call fails for a reason other than "no stream found" (e.g., network error), the if let Ok(...) silently swallows the error and proceeds to add the subject, which could lead to subject conflicts if the subject belongs to a stream that was temporarily unreachable.
