• 🔴 (13:28) User required that a newer turn supersede stale incomplete rows and that the system never resume an older assistant projection.
• 🟡 (13:28) /tmp/opencode/session-recovery-review.1VQHG0/packages/core/src/session/input.ts:498-531 defines promoteSteers(): selects unpromoted delivery="steer" inputs for sessionID with admitted_seq <= cutoff, excludes rows already used as SessionRecoveryTable.continuation_message_id, orders by ascending admitted_seq, and publishes all selected inputs.
• 🟡 (13:28) /tmp/opencode/session-recovery-review.1VQHG0/packages/core/src/session/input.ts:533-559 defines promoteNextQueued(): selects the earliest unpromoted delivery="queue" input for sessionID, excludes recovery continuation inputs, and returns false if none exists or publishes the row and returns true.
• 🟡 (13:28) /tmp/opencode/session-recovery-review.1VQHG0/packages/core/src/session/input.ts:561-599 defines promoteExact(): selects an exact unpromoted queued input by messageID and sessionID; absence dies with Pending recovery input not found: ${messageID}.
• 🟡 (13:28) In promoteExact(), a RecoveryConflict raised during publish() updates SessionRecoveryTable.recovery_error only where execution_id matches, wake_pending=true, and recovery_error is null, then rethrows the defect; non-RecoveryConflict defects are rethrown unchanged.
• 🟡 (13:28) Session projection code validates a recovery target is the latest assistant and dies with Recovery target is not the latest assistant: ${event.data.assistantMessageID} when it is not; recovery creates a prompt using Prompt.make({ text: "continue" }).
