Sync Clarify Boundary State

Record the arrival (before the advancement gate)

After /speckit.clarify updates the active spec, record the boundary arrival FIRST — the sync mints the pending crossing and writes .specrew/runtime/pending-verdict-stop.md, the controller truth the verdict stop renders from. This arrival-first order prevents a stop with no artifact:

$featureJson = Get-Content -LiteralPath .\.specify\feature.json -Raw -Encoding UTF8 | ConvertFrom-Json
$featureRef = Split-Path -Leaf $featureJson.feature_directory
pwsh -File .\.specify\extensions\specrew-speckit\scripts\sync-boundary-state.ps1 -ProjectPath . -BoundaryType clarify -FeatureRef $featureRef

If the sync fails, stop and report the exact file-write error before continuing. If the sync is refused because an earlier crossing is still unapproved (the ratchet), that refusal IS the stop — surface it and wait for the human; do not work around it.

Advancement gate (after the arrival is recorded)

The gate BLOCKS until the human's verdict authorizes this crossing:

. .\.specify\extensions\specrew-speckit\scripts\shared-governance.ps1
$authorization = Test-SpecrewBoundaryAuthorization -ProjectRoot . -CurrentBoundary 'specify' -RequestedBoundary 'clarify'
if (-not $authorization.Authorized) {
  Write-Output (Write-SpecrewBoundaryAuthorizationDirective -CurrentBoundary $authorization.CurrentBoundary -RequestedBoundary $authorization.RequestedBoundary -DirectiveSentinel $authorization.DirectiveSentinel)
  throw $authorization.Reason
}

On a gate block, .specrew/runtime/pending-verdict-stop.md is the controller truth: render the six-section boundary packet from its Boundary to ask for, Human approval phrase, and Marker last line exactly values, then stop for the human's verdict. Do not infer a marker from the phase you are in.
