#4 Split EquipmentDataModel into focused stores
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.

Table/YAML-driven refactor (Layer 1 start)
Move equipment capabilities and the E30 control state machine out of C++
code and into YAML data files; introduce a Router for SECS dispatch;
consolidate small files.
Behavioural changes: none. Demo identical (15 SxFy transactions +
3 equipment-initiated primaries), 67 test cases / 384 assertions still
all green. Structural changes only.
Why
---
The previous server.cpp held the equipment data dictionary (3 SVIDs,
2 ECIDs, 3 CEIDs, 2 alarms, 2 recipes, 4 host commands) as imperative
C++ in a 50-line `populate()` function, and routed inbound messages
through a 150-line if-ladder. Adding a new SVID required a recompile.
Adding a new state transition required editing two switch statements
(`operator_*` and `on_host_request_*`). The control state machine's
behavioural rules were spread across imperative code in two methods.
This is exactly what implementation_plan.md calls out as the wrong
shape: behavioural rules should live in versioned data, and every
runtime/test/analyzer should read from that data rather than re-encode
it. This commit starts that move.
What's new
----------
data/equipment.yaml
Equipment data dictionary. Declarative SVIDs / ECIDs / CEIDs /
alarms / recipes / host commands. Host commands carry their HCACK
ack code plus optional `emit_ceid` and `set_alarm` side-effects.
Adding a new SVID or command is a YAML edit, no recompile.
data/control_state.yaml
The E30 §6.2 control state transition table as data. Each row is
(from, on) -> (to [, then] [, ack]). `then` chains an auto-advance
through the transient AttemptOnline state. The previous
imperative switch is gone.
include/secsgem/config/loader.hpp + src/config/loader.cpp
yaml-cpp-backed loader. `load_control_state(path)` returns a
ControlTransitionTable + initial state; `load_equipment(path, model)`
populates the EquipmentDataModel and returns the device descriptor
(id, MDLN, SOFTREV, optional auto-emit CEID). Surfaces config
errors with file path + field name via ConfigError.
include/secsgem/gem/router.hpp (header-only)
Small (stream, function) -> handler map. Server registers all
handlers once at startup, then the Connection's message handler is
just `router.dispatch(msg)`. Unhandled primaries with W set get
SxF0 by default. Replaces the if-ladder in secs_server.cpp.
include/secsgem/gem/control_state.hpp + .cpp
ControlTransitionTable is the new pure data type. ControlStateMachine
is now a thin engine over the table: `fire(event)` looks up the row,
optionally transitions, optionally chains a `then` transition, returns
the ack code. Behaviour rules no longer live in C++ switches.
The default in-code table matches data/control_state.yaml row for row;
tests rely on it so they don't need the YAML file.
include/secsgem/gem/data_model.hpp + .cpp
`register_command(rcmd, CommandSpec)` replaces the function-handler
signature. CommandSpec = (HostCmdAck, optional emit_ceid, optional
set_alarm). `dispatch_command` returns a CommandResult so the server
can fire the side-effects after S2F42 is sent.
apps/secs_server.cpp
No populate(), no if-ladder. Loads equipment.yaml + control_state.yaml
at startup (clean error on bad config), wires the Router once,
delegates dispatch. Sm change handler reads emit_on_control_change
from the YAML. Welcome S10F3 removed for parity with config (a future
YAML rule could re-introduce it declaratively).
tests/test_loader.cpp (new)
Verifies the YAML loader produces the same shape as the in-code
default table, and that equipment.yaml populates every section
(SVIDs/ECIDs/CEIDs/alarms/recipes/commands). SECSGEM_DATA_DIR
CMake define points at ${CMAKE_SOURCE_DIR}/data so tests don't
depend on cwd.
CMakeLists.txt, Dockerfile
find_package(yaml-cpp) and link. libyaml-cpp-dev added to the
Ubuntu base image (yaml-cpp 0.8 ships the modern target name).
File consolidation
------------------
Five small files removed; their content lives in fewer headers:
- secs2/item.cpp -> inline in secs2/item.hpp
- secs2/message.cpp -> inline in secs2/message.hpp
- hsms/types.hpp -> merged into hsms/header.hpp
- hsms/frame.hpp -> merged into hsms/header.hpp
- hsms/frame.cpp -> merged into hsms/header.cpp
hsms/header.hpp is now "the HSMS wire format" in one place: SType + status
enums + Timers + Header + Frame + constants. All includers updated.
Net effect
----------
Before: equipment data dictionary lived in 50 lines of imperative
populate() inside secs_server.cpp; dispatch in a 20-branch if-ladder.
After: equipment data dictionary lives in 47 lines of YAML; dispatch
is a Router built once. Adding a new capability is now a YAML edit
in the common case.
Test count up to 67 cases / 384 assertions (+4 cases / +106 assertions)
covering the loader and the new table-driven SM paths.
What's NOT changed
------------------
The per-SxFy reply construction still lives in C++ (each message has a
unique body shape). Moving those into YAML/JSON message-shape
definitions is the next refactor step but requires a generic typed
encoder/decoder driven by shape descriptors; out of scope here.
Spooling, the S9 error stream, S1F19/F20, and the other gaps in
COMPLIANCE.md remain unchanged.
