# Phase 165: Real Topic L0 To L2 End-To-End Validation - Context

**Gathered:** 2026-04-12
**Status:** Ready for execution

<domain>
## Phase Boundary

This phase owns the next post-`v1.90` maturity slice.

The phase should:

- start from a real idea rather than a synthetic demo topic
- run through the current public AITP entry surfaces (`explore` and/or
  `bootstrap`)
- keep the run grounded in durable topic/runtime artifacts
- end with a documented bounded outcome and issue ledger

</domain>

<decisions>
## Implementation Decisions

- **D-01:** Treat this as research-utility validation, not as a generic
  coverage or mock-heavy testing milestone.
- **D-02:** Use the current public user-facing entry surfaces first:
  `explore`, `promote-exploration`, `bootstrap`, `loop`, `status`,
  `replay-topic`, and the audit surfaces.
- **D-03:** Require one durable postmortem and one durable issue ledger.
- **D-04:** Do not assume GSD will auto-discover problems from runtime
  artifacts alone; convert every discovered issue into explicit GSD-tracked
  work.

</decisions>

## Deferred Ideas

- multi-user feedback collection beyond the first primary operator run
- broad cross-runtime parity closure beyond the runtime you actually use for the
  first real-topic run
- whole-topic statement-compilation or formalization claims before a real run
  says they are needed
