A null resetValue encoded to null, which wrote an empty string and then handed the
waiter a null target (= any change), fast-pathing on the stale cache and reinstating
the race the overload exists to close. The context parameter is now non-nullable and
the accessor throws ArgumentException before any write. Also: additive-timeout note on
all surfaces, batch-failure message no longer names the bool overload, and the
error-message/batch-failure branches are pinned.

The MES/Delmia handshake fast-paths on the previous run's cached CompleteFlag
because the reset write has not echoed back before the wait registers. An
edge-triggered wait is rejected (a subscription can swallow the reset when the
device flips inside one sampling interval); the fix encodes the reset leg inside
a new WriteBatchAndWaitAsync overload that observes the reset echo before writing
the trigger and returns a phase-aware HandshakeResult.

The Run-inbound-API-method pane rendered one text box per top-level schema
field and coerced the text on the page; an array/object field went through
JsonNode.Parse and, on failure, was SENT AS A STRING, while an empty box was
silently dropped. A required array-of-object parameter (MesMoveOut WorkOrders)
could not be entered at all — QA runs reached the site with "WorkOrders":[].
- The method pane now renders the same shared ParameterValueForm the script
pane uses (typed inputs, nested groups, add/remove list item editors,
$ref:lib: resolution, inline validation), keyed on the method id so a change
of method remounts it. The page keeps ONE value tree and BuildParameters()
serializes it as-is; the flat _inputs / Coerce() / SetInput path is deleted.
- Form | Raw JSON toggle: raw mode is a Monaco json editor for the whole
request body, given the method's root schema for completion, parsed and
schema-validated (InboundApiSchema.Validate) on every edit with the error
inline. Entering raw mode seeds the editor from the tree; leaving it
re-mounts the form over the last valid tree.
- Run is disabled while the form or the raw document is invalid (a required
field left empty disables Run before the first keystroke).
- localStorage per-method entry stores the value tree; on restore it is
validated against the schema and dropped if invalid, which also retires the
pre-#37 flat string-per-field entries.
- ParameterValueForm.ToJsonSchema / JsonElementToObject made internal static
for page reuse.
- Tests: 7 new bUnit tests (WorkOrders array-of-object round-trip to the
RunMethodAsync payload, required list-item gating, invalid raw JSON blocks
Run + shows parse/schema/non-object errors, valid raw JSON sent verbatim and
survives the switch back to the form, method switch resets, persisted tree
restored, legacy flat entry dropped); existing method-pane tests moved to
the form's #param-<field> ids and fill the required field before Run.
Playwright smoke selector moved to #param-Text.
- Docs: design doc, Component-CentralUI.md entry-points bullet, CLAUDE.md.
CentralUI.Tests 1425/1425 green; Playwright project builds.

Both driven from the Mac over the winrm CLI (WinRM 5985 + SMB 445, no helper
on the boxes). Migration 53->55; the first Central boot encrypts
DataConnections.PrimaryConfiguration (dp:protocol:v1:), so rollback is the
COPY_ONLY DB restore, not a binary swap. QA: all four nodes stopped together,
one shared-DB migration, 2 min 35 s window, preflight against a restored clone.

Second slice of the 2026-09-09 whole-system review remediation
(docs/plans/2026-09-09-arch-review.md §10), on top of the High slice 146a1323.
Runtime/devices: SR-2 alarm on-trigger integration scope; SR-3 correlated NativeAlarmActor
subscribe retry; SR-4 immutable audited DB target; SR-5 ordered InstanceActor stop/flush;
SR-12 rehydration fence; SR-13 S&F gate recheck per delivery; DC-4 no OPC UA security
downgrade; DC-5 alarm snapshot for every new subscriber; ORCH-1 sync-dispose joins the pump.
Management/UI: MG-2 site scope on audit tree + Flow Debugger Replay; MG-3 stale-probe memo
removed; MG-4 server-owned bulk-deploy deadline; UI-5 sandbox runs in a killable child
process (new CentralUI.SandboxWorker project); UI-14 bounded sandbox output/IPC.
Edge/audit: EI-1 relay audit ownership; EI-2 SkipBodyCapture suppresses error text; EI-3/EI-11
error-field redaction + caps; EI-4 single relay deadline, pre-execution-only retry; EI-5
authenticated relay provenance; EI-10 body cap before audit read.
Persistence/contracts: DL-1 global Instance.UniqueName unique index + conflict translation;
DL-2 DataConnection protocol config encrypted at rest (migration
20260909203046_EnforceGlobalInstanceNamesAndProtectProtocolConfiguration — coordinated
central upgrade, old binaries cannot read protected rows); DL-3 bounded Replay paging;
DL-6 cross-site Overwrite of a deployed instance rejected; XC-4 proto descriptor contract test.
Config/hygiene: XC-1 central listener isolation by local port; XC-2/XC-3 inert SMTP + cron
keys removed from rig settings; CM-2 env2 bootstrap guard enabled; DC-6 deploy site exit code;
DC-7 notifier retries only explicit standby rejection; XC-5 ClusterClient purged from docs.
Gates recorded in the report: build 0/0, 9 397 passed / 0 failed, rig redeployed on all
eight nodes with the migration applied. 46 Low findings remain open.
FLOW_ONLY note now names step J. Live gate on the docker rig (8 nodes rebuilt
from this branch via docker/deploy.sh, FlowLogDemo seeded by
docker/seed-flow-log-demo.sh — idempotent, add then update proven):
J step logs live+replay -> YES
live: YES root=5793ddc2-5273-4e62-86c2-ccfc8de0e080 logs=3 levels=debug,info,warn scriptRun=Failed error=CALL_FAILED
replay: YES root=5793ddc2-5273-4e62-86c2-ccfc8de0e080 logs=3 levels=debug,info,warn scriptRun=Failed
H, H2 and I stayed YES in the same run.
Browser check (Playwright, /deployment/flow-debugger?executionId=<J root>,
screenshot /tmp/flow-log-demo.png): the SCRIPT RUN node is red with subtitle
"InvalidOperationException: demo failure" and badge "! 1 ≡ 2"; the WRITE node
carries no badge; the strip reads "LOG 0 errors · 1 warnings · 2 info"; the
detail panel opens on "Log (3)" with the full System.InvalidOperationException
block and the three info/debug/warn script lines.
FlowDebugRunner.RunMethodAsync now passes InboundScriptResult.ErrorDetail through to the
synthesized inbound audit row's errorDetail, so a SCRIPT_ERROR run's exception ToString() lands
on AuditDetails.ErrorDetail for the Flow Debugger's inbound node to read (never surfaced to the
HTTP caller). FlowDebugRunResult grows an additive LogsTruncated (default false, last positional
member) reporting the inline FlowTraceCollector's low-priority (ScriptLog) truncation separately
from Truncated (step-row fidelity); RunMethodAsync/RunScriptAsync thread collector.LogsTruncated
through on their two collector-backed results.
