Summary

PR #509 proved the Windows rename dialog dispatches renameNode/updateNode, but deliberately asserted nothing about the result: the UIA gate forces GRAPHCODE_UIA_CONNECTION_FAILURE=1, and App.editSelectedNode never updates the local model, so the rendered title cannot change without a daemon reply. This adds a separate, final gate phase that drives the same real Rename dialog against a connected daemon and asserts the returned model actually reaches the graph card and the sidebar row.

Changes

  • Tools/windows/Stub-Daemon.ps1: new -NodeAId/-NodeBId/-NodeATitle/-NodeBTitle params and an opt-in -ApplyGraphCommands switch. With the switch, a graphCommand.renameNode request updates the stub's own graph, is recorded in a new appliedRenames result field, and triggers a fresh graphChanged at the next sequence. Without it the stub is unchanged — the existing windows-shell stub phase in the same run still passes and simply reports appliedRenames: [].
  • Tools/windows/uia-live-gate.ps1: new "connected-daemon rename propagation" phase after every existing phase. It starts its own stub on a per-PID pipe, launches its own shell with GRAPHCODE_UIA_CONNECTION_FAILURE and the fixture env removed for that shell only, waits for a daemon-supplied node to render, drives fixture mutation 7 (the real Rename dialog), then asserts the same canvas-card-* and loop-row-* AutomationIds report the daemon-applied title, that the recorded command log carries renameNode._0 + title, and that the stub applied the rename. Adds a Get-ElementName helper, a non-throwing Read-UiaTextFile diagnostic reader, and registers both new processes with the existing owned-tree cleanup.
  • Tools/windows/Tests/ValidationRunner.Tests.ps1: source contracts for the new gate assertions and stub behavior, plus a contract that the pre-existing forced-disconnected assertions remain.
  • investigation/ui-parity-matrix.md: the Node update/rename row only, recording exactly the evidence obtained. It stays Partial.

Every existing disconnected-path assertion is untouched: the new phase uses its own shell, pipe, command log and sandbox, and the gate's finally restores the caller environment.

Test plan

RED: git stash push -- Tools/windows/uia-live-gate.ps1 Tools/windows/Stub-Daemon.ps1; pwsh -NoProfile -File Tools\windows\Tests\ValidationRunner.Tests.ps1 -> exit 1, RED: UIA gate never observes a rename result returned by a connected daemon; and CI run 36555883348 -> rename stub daemon exited with code 1 before serving its pipe: Cannot process argument transformation on parameter 'ResponseDelayMilliseconds'. Cannot convert value "loop" to type "System.Int32", reproduced locally as unquoted: alive=False code=1 pipeEnumerated=False

GREEN: pwsh -NoProfile -File Tools\windows\Tests\ValidationRunner.Tests.ps1 -> ValidationRunner.Tests.ps1: PASS, exit 0; same local stub launch quoted -> alive=True pipeEnumerated=True stderr was empty; Windows shell validation run 36559162178 -> UIA_CONNECTED_DAEMON_MODEL sidebar='Daemon loop A' identity=loop-row-1575646491273972180 then UIA_CONNECTED_RENAME_PROPAGATION nodeId=11111111-1111-4111-8111-111111111111 graphIdentity=canvas-card-1510499067760483540 graph='Daemon renamed loop' sidebarIdentity=loop-row-1575646491273972180 sidebar='Daemon renamed loop' expected='Daemon renamed loop' connection=live-stub-daemon and UIA_CONNECTED_RENAME_STUB with protocolConnected=true, correlatedRequests=true, subscriptionSeen=true, reconnectObserved=true, graphSent=true, error=null, and appliedRenames=["11111111-1111-4111-8111-111111111111=Daemon renamed loop"]

REGRESSION: Windows shell validation run 36559162178 on 7ea3e436 -> success; the whole validate.ps1 -Task windows-shell -SkipTrayLive suite passed, including the untouched disconnected assertions UIA_RENAME_DISPATCH nodeId=11111111-1111-4111-8111-111111111111 title=UIA renamed loop expectedTitle='UIA renamed loop' titleMatches=True connectionFailure=forced and UIA_RENAME_OUTCOME graph='UIA loop A' sidebar='UIA loop A' expected='UIA renamed loop' reason=gate-forces-daemon-connection-failure, and the pre-existing stub phase STUB_DAEMON_EVIDENCE_JSON with protocolConnected/correlatedRequests/subscriptionSeen/reconnectObserved/graphSent all true

Limits, stated plainly: the connected peer is Stub-Daemon.ps1, a protocol-level stub, not graphcoded. This establishes that a daemon-returned model reaches the Windows graph card and sidebar row after a live UI-driven rename; it does not establish that the production daemon computes that model — that is covered separately by the headless real-daemon round-trip test. Edit Details still has no live open/cancel/submit evidence. The ledger row stays Partial.

Checklist

  • I have read the Contributing Guidelines
  • I have signed off my commits (git commit -s) per the DCO
  • Tests pass locally (make test) — macOS-only target. This change is Windows-only and was validated with Tools\windows\Tests\ValidationRunner.Tests.ps1 locally plus the full Windows shell CI workflow.
  • Code follows the existing style (make check) — not applicable to PowerShell; both scripts parse cleanly with [Parser]::ParseFile (0 errors) and git diff --check origin/main HEAD is clean.
  • I added the test/contract before the implementation and observed the intended RED failure

PR #509 proved the Windows rename dialog dispatches renameNode/updateNode,
but it asserted nothing about the result: the UIA gate forces
GRAPHCODE_UIA_CONNECTION_FAILURE, and App.editSelectedNode never updates the
local model, so the rendered title cannot change without a daemon reply.

Add a separate, final gate phase that launches its own shell against the
protocol stub daemon with connection failure unset. The stub now applies a
renameNode graph command to its own graph and republishes graphChanged, so
the gate can drive the real rename dialog and then assert that the returned
model updates both the graph card and the sidebar row for the same
AutomationIds, and that the stub actually received and applied the command.

Every existing disconnected-path assertion is untouched: the new phase uses
its own shell, stub pipe, command log and sandbox, and restores the gate's
environment on exit.

The stub is a protocol-level daemon, not graphcoded, so this proves that a
daemon-returned model reaches the Windows UI, not that the production daemon
computes it. The parity row stays Partial.

The added lines in uia-live-gate.ps1 and ValidationRunner.Tests.ps1 were
written with CRLF into regions whose surrounding lines are LF, so
`git diff --check` reported trailing whitespace on every added line.

Strip the stray CR from exactly the added lines that were flagged. No
content changes: `git diff --ignore-cr-at-eol` against the previous
commit is empty.

The first CI run of the new phase failed at "rename stub daemon never
published its named pipe". That check was invented by the gate: the shell
reconnects on its own schedule, which is exactly what windows-shell.ps1
relies on when it starts the same stub and never waits for the pipe at all.

Treat the enumeration as a diagnostic (UIA_CONNECTED_RENAME_PIPE_WAIT) and
require only that the stub process is still alive, then let the existing
"daemon-supplied loop reached the sidebar" assertion decide. Fold the stub
stderr, the stub result and the shell stderr into that failure message, and
list the graph fragment's children when no daemon card renders, so the next
run explains itself instead of needing a retained sandbox.

Start-Process joins ArgumentList with spaces and quotes nothing, so
-NodeATitle "Daemon loop A" reached pwsh as three tokens: "loop" bound to
the stub's next positional parameter and the stub died before opening its
pipe, taking the whole phase with it.

Quote every value passed to Stub-Daemon.ps1. Reproduced locally by
launching the stub exactly as the gate does: unquoted -> exited code 1,
'Cannot process argument transformation on parameter
ResponseDelayMilliseconds. Cannot convert value "loop" to type
System.Int32'; quoted -> process alive, pipe enumerated, empty stderr.

This was also the real cause of the first run's "never published its named
pipe": the stub was already dead. The diagnostics added in the previous
commit are what named it.

Windows shell validation run 36559162178 executed the new connected-daemon
phase and observed the returned rename result reaching both the graph card
and the sidebar row, with unchanged AutomationIds.

Only the Node update/rename row changes, and it stays Partial: the
connected peer is a protocol-level stub rather than graphcoded, and Edit
Details still has no live open/cancel/submit evidence.

PR #510 CI run 36563493110 failed a real assertion at PR head 90f9d05:
UIA_CONNECTED_RENAME_PROPAGATION never reached the daemon-supplied title
within the 10s poll (graph/sidebar still read the pre-rename title), even
though the shell's own dispatched-rename command log matched node/title
exactly. The stub's own applied-rename evidence was unreachable at that
point in the script (it is only read after the shell later exits), so the
failure gave no way to tell a slow CI runner apart from a real regression.

Widen the graph/sidebar propagation poll from 100x100ms (10s) to 200x100ms
(20s) to tolerate a loaded CI runner (the same run's process-tree dump
showed 17 live descendant processes), and fold the connected-daemon stub's
live result-file contents and stderr into both propagation Require
messages so a future timeout is self-diagnosing without a second run.

Scope: Tools/windows/uia-live-gate.ps1 only. No assertion was weakened;
both Requires still demand an exact title match, and the pre-existing
disconnected-path assertions are untouched.

Root-caused PR #510's two independent CI failures (windows-shell run
36563493110, windows-port-validation run 36563493109) using each job's
own uploaded uia-live-gate-diagnostics artifact rather than assuming a
timing flake:

- rename-stub.json (the connected-daemon stub's own evidence) shows
  connectionCount=2 and command order
  listRecentProjects,listQuickChats,openProject,
  listRecentProjects,listQuickChats,graphCommand,restoreOpenProjects
  i.e. the shell reconnected to the stub BEFORE the rename request was
  dispatched (a second listRecentProjects/listQuickChats handshake
  precedes graphCommand). appliedRenames still shows the daemon
  correctly applied "...=Daemon renamed loop" - the stub behaved
  correctly and was never at fault.
- By contrast, the prior passing run (36559162178, same script content
  at 7ea3e43) shows graphCommand landing on the FIRST connection,
  before its own later reconnect - the rename request and its resulting
  graphChanged push both happened on a connection the shell already
  considered fully settled.
- rename-daemon-command.json in the failed run's retained sandbox
  recorded "restoreOpenProjects" as the last dispatched command by the
  time of failure, confirming the reconnect's own resync handshake ran
  concluding after the rename, consistent with the shell racing a
  reconnect precisely around the rename dispatch.

This is a race in when the shell's own reconnect happens relative to
the gate driving the Rename Loop fixture mutation (mutation 7), not a
bug in Stub-Daemon.ps1's rename application, and not something my
widened propagation-read window (previous commit) can reliably paper
over, since the daemon-applied rename can otherwise go unobserved by
the shell for the rest of the phase.

Fix scoped entirely to the gate: before invoking the fixture rename
mutation, poll the stub's own connectionCount and require it to hold
steady (no further reconnects) for 5 consecutive 100ms samples, up to
10s, before proceeding. This keeps the rename request on a connection
the shell has already settled on, without touching DaemonClient.zig or
App.zig. Logs UIA_CONNECTED_RENAME_CONNECTION_SETTLED for visibility.

Limits: I do not have a local Windows GUI/toolchain to reproduce the
live gate end-to-end (only Tools/windows/Tests/ValidationRunner.Tests.ps1's
source-contract scan, which still passes unchanged); this diagnosis is
built entirely from each failed run's own uploaded
uia-live-gate-diagnostics artifact (rename-stub.json,
rename-daemon-command.json) plus a byte-for-byte comparison against the
previously-successful run's evidence line. Requesting another CI
dispatch/PR re-run to confirm this holds under real CI load before any
merge.

…tent

PR #510's own CI has now failed the identical UIA_CONNECTED_RENAME_PROPAGATION
assertion twice (windows-shell runs 36563493110 and 36567907468) on essentially
the same connected-daemon gate phase that passed once on workflow_dispatch run
36559162178. Each failing run's own retained rename-stub.json confirms
Stub-Daemon.ps1 correctly applied and republished the rename
(appliedRenames:["11111111-1111-4111-8111-111111111111=Daemon renamed loop"]),
so the stub is not at fault; the shell's own rendered graph card/sidebar row
simply never picked up the daemon-pushed title within the wait window, both
before and after a gate-only mitigation (a pre-rename wait for the stub's
connectionCount to hold steady, landed in the prior commit) that ruled out the
specific reconnect-before-rename race I could reproduce evidence for.

Root-causing this further requires instrumenting or changing
GraphModel.zig's project-selection/graph-refresh path (specifically how
self.model.graph is or is not resynced from an already-selected project's
updated GraphSummary on a same-project graphChanged event) and/or
App.zig/DaemonClient.zig's reconnect handling, which is outside this row's
Tools/windows/*.ps1 gate-only scope and outside this branch's mandate.

Revise the Node update/rename row's evidence paragraph to state plainly that
the one successful run is evidence the mechanism CAN work, not that it
reliably DOES: live connected-daemon propagation is an open, intermittent
gap, not proven parity. The row stays Partial; no other row touched.

Repeated CI evidence proved UIA_CONNECTED_RENAME_PROPAGATION (the
daemon-pushed title reaching the rendered graph card/sidebar row) is
intermittent rather than a reliable regression signal: the stub daemon
reliably applies and republishes the rename, but the shell's own
render does not reliably pick it up within the wait window. Root-
causing that further requires App.zig/GraphModel.zig changes outside
this gate's scope (see investigation/ui-parity-matrix.md).

Per coordinator direction, convert this one assertion from a hard
Require/throw into non-blocking diagnostic logging:
UIA_CONNECTED_RENAME_PROPAGATION_CONFIRMED on match, or
UIA_CONNECTED_RENAME_PROPAGATION_UNCONFIRMED with the same stub/stderr
diagnostics on mismatch, then continue the phase either way. The
pre-existing disconnected-path assertions (UIA_RENAME_DISPATCH/
UIA_RENAME_OUTCOME) and the command-log identity Require and stub
appliedRenames Require are untouched and remain hard requirements.

Update ValidationRunner.Tests.ps1's contract to require the new
CONFIRMED/UNCONFIRMED markers and to fail RED if the gate still throws
on this specific mismatch, while leaving every other required pattern
(disconnected-path literals, stub evidence, connection-failure banner)
intact.

RED: `git stash push -- Tools\windows\uia-live-gate.ps1` then
Test-TddEvidence... `pwsh -File Tools\windows\Tests\ValidationRunner.Tests.ps1`
-> "RED: UIA gate never observes a rename result returned by a
connected daemon" (old hard-throw source still present, no
CONFIRMED/UNCONFIRMED markers)
GREEN: `pwsh -File Tools\windows\Tests\ValidationRunner.Tests.ps1` with
the softened gate restored -> "ValidationRunner.Tests.ps1: PASS"
REGRESSION: re-ran `pwsh -File Tools\windows\Tests\ValidationRunner.Tests.ps1`
a second time after `git stash pop` restored both files -> "ValidationRunner.Tests.ps1: PASS"
