Summary

• replace v1 channel intent actions with reply, execute, clarify, workflow_proposal, visible_multi_reply, and no_reply
• gate TargetResolver behind validated typed execution
• persist structured clarification fields and projection references
• rebuild the intent table once, deleting v1 rows without aliases or dual reads
• expose v2 intent evidence in the Web inspector

Verification

• Contracts: 35/35
• Core: 356/356
• Web: 42/42
• Web typecheck: pass
• Issue [Bug]: Channel intent selector repeats generic clarification after content continuation #421 focused regressions: 2/2
• Intent and clarification focused daemon tests: 5/5
• Intent v2 migration: 1/1
• runtime single_reply/direct_workflow search: zero matches
• Daemon: 889/890 in the full local run; the only failure was the same pre-existing hard-timeout timing test under load, which passes 1/1 in isolation. GitHub Node 22 CI is the merge gate.
