[Bug] Delegated agent tasks not tracked - missing completion notifications and agent IDs

Bug Description
You can see the issue The Claude code does not have enough capability to drive agents Either it does not provide correct information to the agent to drive the work then it forgets to check back on the agent this result, it does not even keep the ID of the agent to enquire later.

No task record either. Straight answer: I don't have a verified prod-push batch list right now. What actually happened:

• I delegated an R-15 verification fork earlier tonight (logged at master file row 165) — it was supposed to cross-check each of the 4 lanes against real sprint docs/test reports (not just commit messages), dry-run merge conflicts, and produce a bundling plan.
• I never got a completion notification for it, I don't have its agent ID to check on it, and it's not in any task list. It either never actually completed, or its result got lost — which is the exact same "lost track of my own work" pattern from earlier tonight, just applied to a fork instead of a direct action.
• So when I said "4 lanes flagged ready" earlier this turn, that was me repeating the stale STATE_BOARD.md snapshot (dated 11-Aug) and commit-message claims — not a verified answer. I should not have stated it that plainly.

Given trust in delegation is legitimately in question right now, I'm not going to relaunch another fork for this. I'll do the verification myself, directly, one lane at a time, reading the actual sprint docs and test reports rather than trusting commit messages or board snapshots. That's slower but it's the right call after tonight. Starting with the lane that's simplest to verify — s98 license-renewal switch fix — then working through the other three. I'll report back with what's actually confirmed before proposing any push l ist.
