Replace the generic issue reference with a direct link and minimal protocol outline.
“See GitHub Issue for full specification.” is too vague in standalone docs. Please link the exact issue (e.g., #789 URL) and add a short bullet list of the protocol surface (Register, Heartbeat, job assignment, result posting) plus key inputs so this README is useful without extra lookup.

In `@src/index.ts`:
- Around line 42-62: The current try/catch treats any exception thrown inside
the try (including errors from hotRunnerService.shutdown()) as a hotRunnerError
and may trigger the cold fallback; change the control flow so only errors from
initialize/submitBuild trigger fallback: after calling submitBuild and setting
exitCode, call hotRunnerService.shutdown() inside its own try/catch that logs
shutdown failures but does NOT rethrow; keep the outer catch to handle failures
from initialize/submitBuild and only then, when
buildParameters.hotRunnerFallbackToCold is true, call runColdBuild; reference
hotRunnerService.initialize, hotRunnerService.submitBuild,
hotRunnerService.shutdown, and runColdBuild to locate where to add the inner
try/catch and separate error handling.
In `@src/model/input.ts`:
- Around line 291-293: The hotRunnerTransport getter currently asserts arbitrary
strings to the union type; change it to retrieve the raw value via
Input.getInput('hotRunnerTransport'), check it against the allowed set
['websocket','grpc','named-pipe'], return the default 'websocket' when no value
is provided, and throw a clear Error (or process.exit with message) if the
provided value is not one of those options so invalid inputs fail fast; update
the static getter hotRunnerTransport in the Input class to perform this
validation rather than using a type assertion.
- Around line 299-309: The three getters hotRunnerPort, hotRunnerHealthInterval,
and hotRunnerMaxIdle currently parse inputs that can yield NaN; update each to
validate the parsed value is a positive integer (Number.isInteger(parsed) &&
parsed > 0) after calling Input.getInput(...), and if validation fails throw a
clear Error describing the invalid input name and value (fail fast) instead of
returning NaN or silently using it; keep existing defaults only as the string
passed into parseInt but still validate the final numeric result so invalid
strings cause a thrown error.
In `@src/model/orchestrator/services/hot-runner/hot-runner-dispatcher.ts`:
- Around line 80-87: The catch block in the executeWithTimeout path marks the
runner idle even when the underlying HotRunnerTransport.sendJob is still
running, risking reassignment before the job actually ends; update the logic in
the catch around executeWithTimeout/sendJob to distinguish timeout-induced
rejection from real failures (inspect the thrown error or return a timeout
sentinel), and on timeout either keep the runner in a non-idle state (e.g.,
leave state='running' or mark 'timed_out') until sendJob completes or implement
an abort/cancellation flow: add cancellation/abort support to
HotRunnerTransport.sendJob (or pass an AbortSignal from executeWithTimeout),
call the abort in the timeout handler, and only call
registry.updateRunner(runner.id, { state: 'idle', currentJob: undefined }) after
the job has actually finished or after abort completes.
In `@src/model/orchestrator/services/hot-runner/hot-runner-health-monitor.ts`:
- Around line 49-57: When transport is missing (transport =
this.transports.get(runnerId) null check), don't mark the runner immediately as
'unhealthy' and let it be recycled; instead update the registry with a transient
state like 'missing-transport' (use this.registry.updateRunner(runnerId, {
state: 'missing-transport', lastHealthCheck: new Date().toISOString() })), log
with OrchestratorLogger.logWarning as before, and return without triggering the
unhealthy/recycle path (i.e., avoid returning the value that your caller treats
as "unhealthy" or add a short grace window flag) so restored runners can
reattach transports before eviction; ensure corresponding checks elsewhere that
look for 'unhealthy' (or the boolean returned) are adjusted to only recycle true
'unhealthy' states.
- Around line 63-67: The problem is that lastHealthCheck (set in
registry.updateRunner inside hot-runner-health-monitor) is updated on every
successful poll, which prevents idleAge (computed later) from ever reaching
maxIdleTime; fix by separating health polling from activity timestamps: stop
using the poll timestamp as the runner's activity marker and instead update
lastHealthCheck for health status only while using a distinct lastActiveAt (or
preserve runner.createdAt/lastTaskTimestamp) for idle calculations; update
registry.updateRunner to accept and persist a separate lastActiveAt (or only set
lastHealthCheck when health state changes) and change the idleAge computation to
read runner.lastActiveAt (or createdAt/lastTaskTimestamp) when comparing against
maxIdleTime.
In `@src/model/orchestrator/services/hot-runner/hot-runner-service.ts`:
- Around line 144-164: The parseCustomParameters function currently tokenizes
raw by splitting on whitespace which breaks quoted values like -defineSymbols "A
B"; update parseCustomParameters to perform quote-aware tokenization (or use a
regex that matches flag tokens and quoted/unquoted values) so that values
wrapped in single or double quotes are kept as one token, strip surrounding
quotes and unescape inner characters, then proceed with the existing logic that
extracts key (from part.replace(/^-+/, '')) and assigns value (handling
key=value, next-token value, or boolean true); ensure the tokenizer feeds into
the same for-loop/parts handling so variables parts, part, key and the i
increment logic continue to work correctly.
- Around line 106-124: The shutdown() method stops monitoring and disconnects
transports but never unregisters runners from the registry, leaving stale
entries; update shutdown() to iterate over the registered runner IDs (use
this.transports.keys() or the same map used to track runners) and call the
registry removal method (e.g., this.registry.unregisterRunner(id) or the
appropriate unregister method on the orchestrator registry) for each runner
before clearing this.transports, ensuring all registry entries are removed even
if transport.disconnect() fails (handle errors the same way as current
disconnect error handling).
In `@src/model/orchestrator/services/hot-runner/hot-runner.test.ts`:
- Around line 488-491: The test’s mock transport uses sendJob mocked with
setTimeout(60000) which creates a long-lived timer; replace that with a truly
never-resolving promise or use Jest fake timers so no real timer is scheduled.
Concretely, update the mock created by createMockTransport in hot-runner.test.ts
so sendJob returns a Promise that never resolves (e.g., new Promise(() => {}) )
or switch the test to use jest.useFakeTimers() and advance timers as needed
instead of setTimeout, ensuring no 60s timer handle remains.

Don’t let shutdown errors trigger a second build.
In this block, a successful hot build can still fall into fallback if hotRunnerService.shutdown() throws, which may run the same job again via cold build.

Validate hotRunnerTransport instead of casting arbitrary strings.

Timeout path can free a runner that may still be executing.
executeWithTimeout rejects on timer, but the underlying sendJob keeps running. Then the catch block marks the runner idle, which allows reassignment before the original job truly ends.

No-transport runners are aggressively recycled, which can purge restored state too early.
When transport is missing, this marks the runner unhealthy; then non-starting unhealthy runners are recycled in the same cycle. During service initialization restore flows, this can evict persisted runners before transport reattachment.

Idle recycling is neutralized by the current timestamp source.
lastHealthCheck is refreshed on each healthy poll (Lines 65-67), but idle age is computed from that same field (Line 130). In steady state, idle runners never reach maxIdleTime.

Clear timeout handles after Promise.race settles.

lines 283 - 287, The loop in hot-runner-registry.ts that restores runners
accepts entries where the map key id can differ from the payload status.id;
update the restoration logic inside the for (const [id, status] of
Object.entries(data.runners)) block (used with isValidRunnerStatus) to verify
that status.id exists and equals the map key before calling this.runners.set(id,
status); if they don't match, skip the entry (and optionally log or count the
corrupt entry) so downstream code that relies on runner.id won't break.

Job-level continue-on-error masks failures and is inconsistent with other platform workflows.
The macOS workflow applies continue-on-error: true at the job level (line 15), which causes the entire job to report success even if the build fails. This differs from the Ubuntu and Windows workflows, which use step-level continue-on-error with duplicated build steps and retry delays between attempts—allowing the job to fail overall if all retries exhaust.
The macOS workflow contains no retry logic or step duplication, unlike Ubuntu (build-1, Sleep for Retry, build-2) and Windows (build-1, Sleep for Retry, build-2). The existing fail-fast: false (line 17) already prevents one matrix failure from canceling sibling matrix jobs; the job-level continue-on-error goes further by hiding failures from the workflow status entirely.
Consider one of these approaches:
- Implement step-level retry logic consistent with Ubuntu/Windows workflows
- Remove job-level
continue-on-errorif the intent is only to avoid blocking matrix siblings (already handled byfail-fast: false) - Add a comment explaining why macOS builds are expected to be flaky if this is intentional
