Why: Q1 WP5 - platform's SQLite becomes an implementation of the
squad Store port so run state and orchestration state live in one
database, and platform's in-process execution goes through the
Executor port instead of bypassing it (X6).
Evidence: all five modules go vet clean and go test ok, including
engine-on-SQLite (state in DB, no run-level JSON files, second
engine recovers from the same DB), SQLiteStore round trip, and the
full squad compatibility net.
Impact: runState/hitlGate exported so the port is implementable;
Options.Store wires into engineDeps; leader persistence and
checkpoints route through the port; PrepareWorkspace no longer
writes run-level JSON (st.save owns it); platform RunInProcess
takes squad.Executor (callers updated); serve mounts the engine on
platform's RunStore - single orchestration.db for both.

Why: parallel groups dropped a hold, HITL timeouts were unused, the planner failed closed on any model error, and event sequence numbers restarted at 1.
Evidence: GOWORK=off go test -count=1 -race ./squad/ ./squadintent/ ./store/ ./platform/ passed, including TestR2ExpiredDecisionUsesCancel, TestR2IntentStepSkipsRoleRegistry, TestR2PlannerFallsBackAndCapsSteps, TestR2TaskFileUsesLatestBlackboard, TestR2FanoutCancelDoesNotPanic, TestR2EventSeqContinuesAfterRestart, TestR2JournalModeWAL, and TestR2GateReloadSeesNewIntent.
Impact: a failed or held parallel sibling cancels the rest; expired requests synthesize cancel or fail; the intent gate follows Registry.Reload.

Why: A step confirmation cancelled the whole run, approvals and repair budget vanished on restart, and the HTTP server accepted anonymous and oversized requests.
Evidence: GOWORK=off go vet ./... && GOWORK=off go test -count=1 ./... && GOWORK=off go test -race ./squad/... passed. scripts/submodule-consistency.sh ok.
Impact: Approve and skip apply to one step; runstate.json and unix flock survive restart; wakeup leaves permission holds pending; serve defaults to loopback and requires a token off-loopback.
