+# Sprint 20260313_001 - Platform Scratch Iteration 007 Full Route Action Audit
+
+## Topic & Scope
+- Wipe Stella-owned runtime state again and rerun the documented setup path from zero state.
+- Re-enter the application as a first-time user after bootstrap and rerun the full route, page, and page-action audit with Playwright.
+- Group any newly exposed defects before fixing so the next commit closes a full iteration rather than a single page slice.
+- Working directory: `.`.
+- Expected evidence: wipe proof, setup convergence proof, fresh Playwright route/action evidence, grouped defect list, fixes, and retest results.
+
+## Dependencies & Concurrency
+- Depends on local commit `27d024705` as the clean baseline for the next scratch cycle.
+- Safe parallelism: none during wipe/setup because the environment reset is global to the machine.
+
+## Documentation Prerequisites
+- `AGENTS.md`
+- `docs/INSTALL_GUIDE.md`
+- `docs/dev/DEV_ENVIRONMENT_SETUP.md`
+- `docs/qa/feature-checks/FLOW.md`
+
+## Delivery Tracker
+
+### PLATFORM-SCRATCH-ITER7-001 - Rebuild from zero Stella runtime state
+Status: DONE
+Dependency: none
+Owners: QA, 3rd line support
+Task description:
+- Remove Stella-only containers, images, volumes, and the frontdoor network, then rerun the documented setup entrypoint from zero Stella state.
+
+Completion criteria:
+- [x] Stella-only Docker state is removed.
+- [x] scripts/setup.ps1 is rerun from zero state.
+- [x] The first setup outcome is captured before UI verification starts.
+
+### PLATFORM-SCRATCH-ITER7-002 - Re-run the first-user full route/page/action audit
+Status: DONE
+Dependency: PLATFORM-SCRATCH-ITER7-001
+Owners: QA
+Task description:
+- After scratch setup converges, rerun the canonical route sweep plus the full action audit suite and enumerate every newly exposed issue before repair work begins.
+
+Completion criteria:
+- [x] Fresh route sweep evidence is captured on the rebuilt stack.
+- [x] Fresh action sweep evidence is captured across the current aggregate suite.
+- [x] Newly exposed defects are grouped before any fix commit is prepared.
+
+### PLATFORM-SCRATCH-ITER7-003 - Repair the grouped defects exposed by the fresh audit
+Status: DONE
+Dependency: PLATFORM-SCRATCH-ITER7-002
+Owners: 3rd line support, Architect, Developer
+Task description:
+- Diagnose the grouped failures exposed by the fresh audit, choose the clean product/architecture-conformant fix, implement it, and rerun the affected verification slices plus the aggregate audit before committing.
+
+Completion criteria:
+- [x] Root causes are recorded for the grouped failures.
+- [x] Fixes land with focused regression coverage where practical.
+- [x] The rebuilt stack is retested before the iteration commit.
+
+## Execution Log
+| Date (UTC) | Update | Owner |
+| --- | --- | --- |
+| 2026-03-13 | Sprint created for the next scratch iteration after local commit `27d024705` closed the previous clean baseline. | QA |
+| 2026-03-13 | Removed Stella-only containers, `stellaops/*:dev` images, Stella compose volumes, and the `stellaops` / `stellaops_frontdoor` networks to return the machine to zero Stella runtime state for the new iteration. | QA / 3rd line support |
+| 2026-03-13 | The zero-state setup rerun completed cleanly: `36/36` solution builds passed, the full image matrix rebuilt, platform services converged, and `61/61` Stella containers are healthy on `https://stella-ops.local`. | QA / 3rd line support |
+| 2026-03-13 | Fresh canonical route verification completed cleanly on the rebuilt stack: `111/111` routes passed with no route regressions or runtime issues recorded in the route sweep artifact. | QA |
+| 2026-03-13 | The full first-user aggregate Playwright audit completed cleanly: `20/20` suites passed, including the explicit user-reported admin/trust/reporting checks, search route matrix, search result action sweep, and the uncovered-surface release/security/evidence adjacency sweep. No grouped product defects were exposed in this scratch cycle. | QA |
+| 2026-03-13 | The scratch iteration runner was hardened after root-causing a PowerShell pipeline contract bug: native child-process stdout was leaking into JSON-returning helper calls and corrupting typed audit results. `Invoke-External` now streams native output to the host while preserving object-only return values for the audit summary pipeline. | 3rd line support / Developer |
+
+## Decisions & Risks
+- Decision: each scratch iteration remains a full wipe -> setup -> route/action audit -> grouped remediation loop; if the audit comes back clean, that still counts as a completed iteration because the full loop was executed.
+- Risk: scratch rebuilds remain expensive, so verification stays Playwright-first with focused test/build slices rather than indiscriminate full-solution test runs.
+- Decision: iteration 007 closes without product-code fixes because the full scratch audit stayed clean after the runner contract bug was removed; the only change required this cycle was to keep the automation truthful so future scratch iterations do not misclassify audit output.
+
+## Next Checkpoints
+- Start iteration 008 from a fresh Stella-only wipe.
+- Rerun the documented zero-state setup path and then the full Playwright route/page/action audit before considering any fixes.
