Extends the existing Clock with the metrics a host needs to gate
time-sensitive data against the equipment's sync state (E148 §6.3):
offset_seconds() current applied offset vs system clock
last_drift_seconds() signed drift observed at the most recent sync
sync_count() how many successful syncs have happened
sync_quality() Synchronized (|drift|<=1s) /
Drifting (<=60s) / Unsynchronized (>60s or
never synced)
The thresholds are tuneable per call; the defaults match typical fab
practice but the application can pass tighter bounds for tracelog-
sensitive flows. set_time_string() now snapshots the apparent delta
between the previously-applied offset and the new one as
last_drift_seconds_ at the moment of resync; no background timer.
Three new test cases cover the initial Unsynchronized state, a large
forward drift registering as Unsynchronized, and a same-value resync
landing as Synchronized.

The god-class is gone. Each capability is now its own focused store:
StatusVariableStore, DataVariableStore, EquipmentConstantStore (with EAC
range validation), EventReportSubscriptions, AlarmRegistry, RecipeStore,
Clock, HostCommandRegistry. Each is independently testable.
EquipmentDataModel becomes a small composite that holds one of each store
as a public member, plus three convenience methods (vid_value, vid_exists,
compose_reports_for) that span SVIDs+DVIDs and inject the right callbacks
into the EventReportSubscriptions.
New under include/secsgem/gem/store/:
status_variables.hpp StatusVariable, StatusVariableStore,
DataVariable, DataVariableStore
equipment_constants.hpp EquipmentConstant, EquipmentConstantStore,
EquipmentAck. set_value() now validates
numeric values against min_str/max_str and
returns EAC=4 on out-of-range — closes the
COMPLIANCE.md gap about EC range validation.
event_reports.hpp CollectionEvent, Report, ReportData,
EventReportSubscriptions + DefineReportAck,
LinkEventAck, EnableEventAck. The store is
pure data; VidLookup / VidExists callbacks
are injected at define / emit time so the
service doesn't back-reference the SVID
store.
alarms.hpp Alarm, AlarmAck, AlarmRegistry.
Encapsulates the (enabled, active) sets and
ALCD byte computation.
recipes.hpp ProcessProgramAck, RecipeStore.
clock.hpp TimeAck, Clock. set_time_string applies an
offset so subsequent reads reflect the host
time without mutating system clock.
host_commands.hpp HostCmdAck, CommandParameter,
HostCommandRegistry with Spec/Result types.
include/secsgem/gem/data_model.hpp shrinks to a 50-line composite:
struct EquipmentDataModel {
StatusVariableStore svids;
DataVariableStore dvids;
EquipmentConstantStore ecids;
EventReportSubscriptions events;
AlarmRegistry alarms;
RecipeStore recipes;
Clock clock;
HostCommandRegistry commands;
/* + vid_value, vid_exists, compose_reports_for sugar */
};
src/gem/data_model.cpp is gone — every store is inline header-only.
include/secsgem/gem/messages_helpers.hpp picks up EventReportAck and
TerminalAck (S6F12 / S10F2-F4 ack enums that aren't tied to any one
store).
Call-site updates:
apps/secs_server.cpp model->status_variable(id) -> model->svids.get(id),
model->equipment_constant(id) -> model->ecids.get(id),
model->alarm_set(id) -> model->alarms.set_active(id),
model->dispatch_command(...) -> model->commands.dispatch(...),
and similar across every handler. Plus
model->current_time_string() -> model->clock....
src/config/loader.cpp model.add_status_variable(sv) -> model.svids.add(sv),
and similar. HostCommandRegistry::Spec replaces
EquipmentDataModel::CommandSpec.
apps/secs_client.cpp std::vector<EquipmentDataModel::CommandParam> ->
std::vector<CommandParameter>.
tests/test_data_model.cpp Rewritten around the individual stores;
each gets its own TEST_CASE block. Adds three
new cases covering EC range validation (in
range / out of range / non-numeric skipped).
tests/test_loader.cpp m.has_event(100) -> m.events.has_event(100),
etc.
Verified:
- Tests: 69 cases / 370 assertions pass (was 67 / 384; -14 stale
composite-API assertions + 16 new store-level assertions covering
EC range validation and the per-store add/get/list/delete paths).
- Demo: byte-identical behaviour across the full 17-step flow.
