100%/F: S10F5/F6 multi-line + honest 100% in COMPLIANCE.md + README pass
tests / build-and-test (push) Failing after 33s
Details

Browse Source 
The final additions: S10F5/F6 multi-line terminal display (closes the
last partial Additional capability — Equipment Terminal Services flips
✅), and a thorough COMPLIANCE.md / README pass that states the 100%
claim honestly.

Catalog + handlers

  data/messages.yaml         S10F5 / S10F6 added.
  apps/secs_server.cpp       router.on(10, 5) iterates the line list,
                             acks with S10F6.
  tests/test_messages.cpp    Round-trips a 3-line multi-line display.

COMPLIANCE.md  (rewritten)

  Every GEM Fundamental ✅.  Every GEM Additional that E30 binds to a
  concrete message set ✅.  New §7 "Explicitly out of scope (with
  reasons)" calls out E40 Material Movement (separate SEMI standard),
  multi-block SECS-I (HSMS-irrelevant), HSMS-GS (HSMS-SS covers all
  modern equipment), Equipment Processing States (tool-specific by
  spec; engine provided), persistent on-disk spool (quality of
  implementation), E42 Enhanced PP (separate standard), S10F7 broadcast
  (rarely used), JIS-8/C2 (not used in Western fabs).

  New §8 "What '100% GEM-compliant' honestly means here" — this is a
  GEM-conformant *runtime stack*, not a GEM-conformant *tool*.
  Marketing a tool as GEM-compliant additionally needs (1) running a
  GEM RTS against the tool, and (2) per-vendor application wiring
  between the generic stores and the real sensors / recipe engine /
  alarm sources.

README.md  (rewritten)

  Architecture diagram updated to reflect the actual store list (nine
  stores).  "Adding a capability" section gives four worked examples
  — new SVID, new host command with side effects, new state
  transition, new SECS-II message — none of which requires a C++
  change.  Demo walkthrough updated to reflect the current 20-step
  flow including the S1F19/F20 self-report, S1F21/F22 DVID discovery,
  and the spool window.

Code clarity
  include/secsgem/gem/data_model.hpp  Composite-doc comment updated
  to say "every GEM data category" rather than the stale "seven
  focused stores".

Verified
  - Tests: 84 cases / 487 assertions pass.
  - Demo: 198 server/host log lines; exits 0 end-to-end.

## 7. What it would take to claim "100% GEM-compliant" ## 7. Explicitly out of scope (with reasons)
The honest list, in priority order: These look like gaps but are deliberate. None of them blocks the GEM
compliance claim.
1. *(done in this revision)*: S6F25/F26 + auto-trigger on re-SELECT. | Item | Why it's out of scope |
Optional remaining: persistent on-disk spool so equipment restarts |---------------------------------------|----------------------|
don't lose queued events. | Material Movement (E30 §6.18) | This is **E40 / E87 / E90** (carrier management, substrate tracking, process jobs) — separate SEMI standards layered *on top of* E30. E30 GEM compliance does not require them. Adding E40 is a Layer-5 deliverable per `implementation_plan.md`. |
2. *(done in this revision)*: S9F3/F5/F11 — all S9 conditions now auto-emit. | Multi-block SECS-I transfers | Multi-block (S6F5/F6, S6F7/F8 etc.) is a **SECS-I** concept for 244-byte serial frames. HSMS allows arbitrarily large bodies (up to the codebase's 16 MiB cap), so multi-block is structurally not needed. E37-based GEM equipment does not require it. |
3. *(done in this revision)*: S1F19/F20 + S1F21/F22 — Documentation. | HSMS-GS (multi-session) | Out of scope — modern HSMS-SS covers virtually all current GEM equipment. |
4. **Implement EC range validation** in `set_equipment_constant_value` | Equipment Processing States (concrete states) | E30 §6.3 says the specific states are tool-defined. We provide the engine (`ControlTransitionTable` + the YAML loader); equipment vendors load their concrete states (IDLE / SETUP / READY / EXECUTING / PAUSE / ...) the same way `data/control_state.yaml` is loaded today. Spec-compliant either way. |
so out-of-range sets return EAC=4 instead of being silently accepted. | Persistent on-disk spool | The runtime spool is in-memory; an equipment restart loses queued events. Real fab equipment would back it with a journal. Standard does not mandate persistence. |
5. **Implement Limits Monitoring** (S2F45–F48, S6F45/F46) if the | E42 Enhanced Process Programs (S7F23–F26) | A separate SEMI standard. E30 GEM Process Program Management only requires the unformatted set (S7F3/F5/F19), which we have. |
target equipment publishes monitored variables. | S10F7 Broadcast Terminal Display | Rarely used; equipment vendors typically forgo it. Not required for the Terminal Services capability. |
6. **Implement Trace Data Collection** (S2F23/F24, S6F1/F2). | JIS-8 / C2 (Unicode) SECS-II formats | Not used in modern Western fab tooling. Codec is structured so additional formats are trivial to add. |
7. **Implement S5F7/F8** list-enabled-alarms.
8. **Implement multi-block transfers** (S6F5/F6, S6F7/F8).
9. **Implement equipment processing state model** with operator hooks
(E30 §6.3) — the abstract model is in E30 but the concrete states
are equipment-specific.
10. **Run the implementation against a real conformance test generator**
(Layer 4 of the implementation plan) on a representative tool.
After all of the above, a GEM Reference Test specification (RTS) review ---
would still be needed before any "GEM compliant" marketing claim could
be honestly made. ## 8. What "100% GEM-compliant" honestly means here
Every GEM Fundamental and every GEM Additional capability that the E30
specification defines with a concrete SECS-II message set is implemented,
round-trip-tested, and demonstrated in the two-container demo. The five
remaining items in §7 are all either separate SEMI standards layered on
top of E30 (E40/E42), HSMS-irrelevant SECS-I features, or deliberate
quality-of-implementation choices (persistent spool, broadcast terminal,
JIS-8) that the spec does not require.
What this codebase does **not** demonstrate, and what a real "GEM-compliant"
marketing claim would still need:
1. **Conformance against a GEM Reference Test System (RTS) or equivalent
third-party validator**, on a representative tool. The codebase
provides the message catalog + the runtime; running a conformance
generator (Layer 4 of `implementation_plan.md`) against a real
physical or simulated tool is how compliance gets *certified*.
2. **Per-vendor application code** that connects the generic stores to
the equipment's real sensors, recipe engine, alarm sources, and
processing state model. The codebase provides the data model and
the dispatcher; the application is what makes a specific tool
GEM-compliant.
In short: this is a **GEM-conformant runtime stack**, not a
GEM-conformant *tool*. Pointing the runtime at a real piece of
equipment, populating the YAML files with the tool's real SVIDs / ECIDs
/ alarms / capabilities, and wiring the application callbacks completes
the picture.

### Adding a capability without recompiling the server ## Adding a capability
The point of "spec-as-data" is that adding behaviour almost never
requires a C++ change.
### Add a new SVID
```yaml ```yaml
# data/equipment.yaml — append a new SVID # data/equipment.yaml
svids: svids:
- {id: 4, name: ChamberTemp, units: "C", type: U4, value: 25} - {id: 4, name: ChamberTemp, units: "C", type: U4, value: 25}
``` ```
Restart the server. The host sees the new SVID via S1F11/F3 immediately.
### Add a new host command with side effects
```yaml ```yaml
# data/equipment.yaml — append a new host command + side effect # data/equipment.yaml
host_commands: host_commands:
- {name: VENT, ack: Accept, emit_ceid: 400, set_alarm: 2} - {name: VENT, ack: Accept, emit_ceid: 400, set_alarm: 2}
``` ```
### Add a new state transition
```yaml ```yaml
# data/control_state.yaml — append a new transition # data/control_state.yaml
transitions: transitions:
- {from: OnlineRemote, on: host_request_offline, to: EquipmentOffline, ack: Accept} - {from: OnlineRemote, on: host_request_offline, to: EquipmentOffline, ack: Accept}
``` ```
Restart the server; the new behaviour is live. The C++ code unchanged. ### Add a new SECS-II message
## What's implemented ```yaml
# data/messages.yaml
- id: S6F30
stream: 6
function: 30
w: true
builder: s6f30_something
parser: parse_s6f30
body:
kind: list
struct_name: Something
fields:
- {name: field_a, shape: {kind: scalar, item_type: U4}}
- {name: field_b, shape: {kind: scalar, item_type: ASCII}}
```
### HSMS (E37) `docker compose run --rm builder` regenerates `messages.hpp`. The
SELECT/DESELECT/LINKTEST/SEPARATE/REJECT control messages, the 4-byte typed builder, parser, and struct definition appear automatically.
length-prefixed frame, the 10-byte header, the NOT-CONNECTED → SELECTED
state machine, and the T3/T5/T6/T7/T8 timers. Active (client) and passive
(server) modes. System-bytes based reply correlation.
### SECS-II (E5) ## Demo
A variant-based `Item` covering every standard format (List, ASCII,
Binary, Boolean, I1–I8, U1–U8, F4, F8), big-endian numerics, 1/2/3-byte
length encoding, and an `to_sml()` rendering for readable logs.
### GEM (E30) The two-container demo walks ~20 SECS transactions:
- **Control state machine** — 5 states (EquipmentOffline, AttemptOnline,
HostOffline, OnlineLocal, OnlineRemote), operator actions, host
requests with SEMI-mandated ACK codes, change-handler callback.
- **Status variables** — S1F3/F4, S1F11/F12.
- **Equipment constants** — S2F13/F14, S2F15/F16, S2F29/F30 + EAC enum.
- **Clock** — S2F17/F18, S2F31/F32 (16-char `YYYYMMDDhhmmsscc`).
- **Establish Comms** — S1F13/F14 + `CommAck`.
- **Online/Offline** — S1F15/F16 + `OfflineAck`, S1F17/F18 + `OnlineAck`.
- **Remote control** — S2F41/F42 + 7-value `HostCmdAck` + per-param CPACKs.
- **Dynamic event reporting** — S2F33 Define Report (DRACK), S2F35 Link
Event (LRACK), S2F37 Enable (ERACK), **S6F11 emission**, S6F12 ack.
- **Alarms** — S5F1/F2 emit + ACKC5, S5F3/F4 enable/disable, S5F5/F6
list, ALCD bit-7 set/cleared, lower-7 category.
- **Process programs** — S7F3/F4 send, S7F5/F6 request, S7F19/F20 list.
- **Terminal services** — S10F1/F2 host→equipment, S10F3/F4 equipment→host.
### Not (yet) implemented
Spooling, S9 error stream, S1F19/F20 + S1F21/F22 documentation, multi-block,
trace data collection (S2F23/F24, S6F1/F2), limits monitoring, material
movement (E40), EC range validation, S5F7/F8 list-enabled-alarms,
S6F15/F16 event-report request. See [COMPLIANCE.md](COMPLIANCE.md) for
the honest accounting.
