[Entity-Service] Run the CSM-native SLA engine on every data source, and fix CompleteClock ignoring paused time - #3023
Two independent fixes found while verifying the CSM-native SLA engine against a spec comparison doc.
1. The SLA engine's own clock-registration trigger was missing on the plain-Postgres path.RegisterCaseClocks (the call that actually creates a case's SLA clocks) was only ever wired into the external-system-backed case service's CreateCase. caseService.CreateCase (NewCaseService, used for the plain-Postgres data source with no external-system mirror at all) never called it — so a case created there got no SLA tracking at all from creation onward, regardless of severity, unless its severity happened to change later (which calls ReviseCaseClocks, registering clocks as an unintended side effect).
Fixed by calling RegisterCaseClocks directly inside caseService.CreateCase, wired in via a new WithSLAEngine post-construction step — the same decorator shape as the existing WithCSEngineerRole/WithProductCategoryEnforcement, so every one of NewCaseService's 60+ existing call sites (every test, every other data-source branch) keeps compiling unchanged.
Also added CSM_SLA_ENGINE_ENABLED (default true) — an explicit, named toggle replacing what used to be an implicit "runs wherever a database happens to be configured" posture. The engine now runs on every data source by default, alongside whatever the external system's own SLA engine may independently be tracking for the same case (both already coexist in the same sla table today, distinguished by source='CSM'/'SERVICENOW' — this makes that an explicit, documented, operator-controllable decision rather than an accident of wiring).
2. CompleteClock ignored accumulated pause time entirely. It used a bare NOW() - start_on, with no account for pause_duration — so a clock paused for a real stretch of time, then resumed and completed, had its final business_duration/business_elapsed_percentage count that entire pause as elapsed working time. Fixed the same way SetPaused's own pause-time freeze and sla_live's live IN_PROGRESS/BREACHED calculations were already fixed (#3014/#3015) — subtract pause_duration (and, defensively, any still-open pause segment) from the elapsed/remaining/percentage calculation at completion time too. Also finalizes a still-open pause when a clock completes directly from a paused state (e.g. a preceding resume failed and was logged-and-ignored), folding the open segment into pause_duration and clearing paused_on instead of leaving a completed clock reporting as paused.
Test plan
go build ./... / go vet ./... clean
go test ./... passes
New unit tests: TestCaseService_CreateCase_RegistersSLAClocks/_NonCaseTypeSkipsSLARegistration/_NilSLAEngineIsNoOp, TestLoad_CSMSLAEngineEnabled
New integration tests (TestSLAEngineIntegration_CompleteClockSubtractsPauseDuration, TestSLAEngineIntegration_CompleteClockFinalizesAnOpenPause) run directly against the real staging database (not just mocked), confirming the exact numbers
gosec/govulncheck clean (no new findings)
Merges cleanly against upstream/dev-app-csm-portal
Added a built-in SLA clock engine for cases, enabled by default across data sources. It can be disabled to use ServiceNow-synced SLA records as the sole source of SLA information.
Newly created cases now receive SLA clocks when the engine is enabled; other case-like request types do not.
Bug Fixes
SLA completion calculations now exclude paused time, including pauses that are still open when a clock is completed.

Walkthrough
The entity service adds a configuration flag for the CSM SLA engine, connects eligible case creation to SLA clock registration, and adjusts clock completion calculations to exclude paused time.
Changes: CSM SLA engine
Layer / File(s)
Summary
Configure the CSM SLA engine entity-service/.env.example, entity-service/internal/config/config.go, entity-service/internal/config/config_test.go
Adds CSM_SLA_ENGINE_ENABLED, which defaults to enabled and is disabled by a trimmed, case-insensitive "false". The environment example documents the setting and its effect on CSM-native SLA row creation.
Wire case creation to SLA clock registration entity-service/internal/server/routes.go, entity-service/internal/service/case_service.go, entity-service/internal/service/case_service_sla_registration_test.go
The router constructs the engine when a database is available and the setting is enabled. The case service registers clocks after creating a "case" request when an engine is attached. Tests cover registration, excluded request types, and a nil engine.
Subtract pause time at clock completion entity-service/internal/repository/sla_engine_repo.go, entity-service/internal/repository/sla_engine_repo_integration_test.go
CompleteClock subtracts accumulated and currently open pause time when calculating elapsed percentage, business duration, and remaining duration. Integration tests check pause duration, adjusted completion values, and clearing an open pause.

Merge Risk: Moderate · up to f77b4
Turning off the engine can leave existing SLA clocks visible but stale. Plan how to handle those clocks before using the kill switch; the default-on case-creation wiring is not blocked by the handler setup.

- Around line 384-385: Update the completion UPDATE in CompleteClock to finalize
any open pause by adding the interval since paused_on to pause_duration and
clearing paused_on; leave pause_duration unchanged when no pause is open, and
preserve the completedElapsedExpr calculation.
Review comments at @entity-service/internal/server/routes.go:
- Line 931: Update the CSM engine setup guarded by cfg.CSMSLAEngineEnabled so
disabling the engine also retires existing active CSM clocks or explicitly
excludes them from unscoped SLA reads. Preserve normal reader behavior for
clocks when the engine is enabled.

…SLA_ENGINE_ENABLED's cutover limitation
Addresses CodeRabbit review on PR wso2-open-operations#3023:
- CompleteClock now folds any still-open pause segment into pause_duration
and clears paused_on, instead of leaving a completed clock reporting as
paused with an incomplete pause total (reachable when a preceding resume
fails and is logged-and-ignored).
- CSMSLAEngineEnabled's doc comment now states explicitly that disabling it
only stops new writes -- in-flight CSM clocks are left stale, not retired
or excluded from reads -- since deciding how to handle them is a product
decision out of scope for this toggle.

…and fix CompleteClock ignoring paused time
Two independent fixes:
1. The CSM-native SLA engine's own clock-registration trigger
(RegisterCaseClocks) was only ever wired into snCaseService's CreateCase
-- the plain-Postgres CaseService (NewCaseService, used for
DATA_SOURCE=postgres with no ServiceNow mirror at all) never called it,
so a case created there got no SLA tracking whatsoever from creation
onward, regardless of severity, until/unless its severity happened to
change later (which calls ReviseCaseClocks, registering clocks as a side
effect). caseService.CreateCase now registers clocks directly, the same
way snCaseService.CreateCase already does, wired in via a new
WithSLAEngine post-construction step (same shape as WithCSEngineerRole)
so every existing NewCaseService call site keeps compiling unchanged.
Also added CSM_SLA_ENGINE_ENABLED (default true), an explicit, named
toggle replacing what used to be an implicit "runs wherever a database
happens to be configured" posture -- the engine now runs on every data
source by default, alongside whatever ServiceNow's own SLA engine may
independently be tracking for the same case (both already coexist in the
same "sla" table today, distinguished by source='CSM'/'SERVICENOW'; this
just makes that an explicit, documented, operator-controllable decision
instead of an accident of how routes.go happened to be wired).
2. CompleteClock used a bare "NOW() - start_on" with no account at all for
s.pause_duration -- a real, reported bug: a clock paused for a real
stretch of time, then resumed and completed, had its final
business_duration/business_elapsed_percentage count that entire pause as
elapsed working time. Now subtracts pause_duration (and, defensively, any
still-open pause segment), the same correction already applied to
SetPaused's own pause-time freeze and to sla_live's live IN_PROGRESS/
BREACHED calculations.
Both fixes verified with new tests, including an integration test for each
run directly against the real staging database (not just mocked/local),
confirming the exact numbers.
