weichen f1302ed5b3 Enable canonical versioned Go module consumption 
Why: Allow consumers to download an immutable module revision without nested source checkouts or local path replacements.

Evidence: SELF package tests and the prior canonical-path rejection are recorded in the Dev dependency-workspace task card; remote consumption is replayed against the committed candidate.

Impact: Change the module identity and its Go imports while preserving API behavior. Existing historical submodule revisions remain buildable.

weichen 70afe40b00 Retire the legacy workflow executor and switch squad steps to agent-native (Q3 WP2)
ci / vet-and-test (pull_request) Successful in 47s
Details 
Why: Q3 WP2 retires the SpawnSubagent-compression execution path: all
WorkflowDef execution now goes through the wfcompile compiled graph, and
squad steps run on the agent-native kernel backend instead of the
agent-system step backend.

Evidence: runtime-level P4 parity tests (workflow_compiled_test.go):
registered branch lookup/errors, planned branch confirmation gate +
dynamic 8-step cap fail-closed before any HITL, model script switch
default-off, missing-slot HITL collection with compile-time rendering,
judge stream routed to the configured lightweight model (nil = fail-closed
verifier-unavailable). squadadapter TestOrchestrateRunsOnKernelStub:
four-phase skeleton runs end-to-end on the kernel stub (write_file
materialization, seeded skills, exec allowlist). server TestSquadOrchestration
reworked: kernel steps run in-process (no subagent child runs). Full
backend suite green; wfcompile/squadadapter/runmgr green with -race
(pre-existing llm_test fake race on main recorded as debt, CI does not
gate -race).

Impact: DELETED runtime/workflow.go + workflow_script.go (legacy step loop,
critic, script host) and their tests; squadadapter stepBackend
'agent-system' + profileForRole deleted; BuildBackends exported and
registers only agent-native; Orchestrate DefaultBackend -> agent-native;
builtin roles declare agent-native with write_file added to allowlists and
writer run_shell -> run_command (kernel tool name); runmgr default workflow
runner -> CompiledWorkflowRunner; mock #workflow demo runs compiled
(host-only steps). Model script branch keeps the single script-level
confirmation (no extra plan confirmation), matching legacy.

weichenandCursor b8e8cfb754 Wire the squad native adapter instead of the core registration 
Why: Backend has to keep the same squad runs after the core stopped importing agent-native. The adapter module owns the concrete client.
Evidence: GOWORK=off go test -count=1 ./internal/... passed.
Impact: AgentNativeOptions now returns the adapter config. Default roles still use the agent-system backend.

weichenandCursor cd74434b4f Stream tool progress and drop hard agent limits 
Why: Tool calls stayed invisible until execution finished, and turn, tool, timeout, and output caps stopped long tasks early.
Evidence: go test ./internal/runtime/ ./internal/tools/ ./internal/prompts/ ./internal/squadadapter/ ./internal/runmgr/ ./internal/app/ ./internal/settings/
Impact: tool.call.delta and tool.output reach the client; default profile, subagents, and squad no longer cap turns or tool calls; exec timeout defaults to 600s with no hard ceiling. A profile or subagent maxTurns above 0 still applies.

weichenandCursor 268f4a9abf Route conversations through a squad entry when selected 
Why: Squad steps previously ran without tools, and the product had no way to make the squad the conversation entry without losing streaming, cards, or the deliverable guard.
Evidence: go test ./... -count=1 passed, including streaming, cardflow, false-deliverable rejection, tool allowlist, model routing, usage, cancel, and turn and tool budgets.
Impact: runtime.entry defaults to direct. squad uses one kernel step for simple work and the leader for the rest. squad_orchestrate is hidden in that mode. The default is not switched.
