+# Phase 47 Main-Path Product Containment
+
+Date: 2026-05-16
+
+## Scope
+
+This report closes the Phase 47 main-path product containment work item.
+
+Issue: `#369 Phase 47: main-path product containment`
+
+Goal: verify that the default Mirror operator path remains centered on comparison, evidence, and eval review while packet-heavy or legacy operations remain secondary.
+
+## Direct Evidence
+
+- `frontend/src/app/page.tsx:37` keeps `Advanced Review` as the third top-level homepage action, after branch comparison and claims/evidence (`frontend/src/app/page.tsx:49`, `frontend/src/app/page.tsx:52`, `frontend/src/app/page.tsx:55`).
+- `frontend/src/app/page.tsx:42` and `frontend/src/app/page.tsx:45` describe the Phase 1 public path as deterministic-only and explicitly not real-world prediction, real-person replica, political persuasion, or high-risk decision tooling.
+- `frontend/src/app/page.tsx:80` states that runtime mutation, create-world, corpus upload, Hosted GPT, BYOK, auth, payment, database storage, and quota systems are reserved for later phases.
+- `frontend/src/app/review/page.tsx:103` through `frontend/src/app/review/page.tsx:107` frame `/review` as a deeper workspace after the public guided demo and keep it read-only for public deployments.
+- `/review` section navigation orders the page as scorecard, trace/claims, reference, then advanced operations (`frontend/src/app/review/page.tsx:113`, `frontend/src/app/review/page.tsx:116`, `frontend/src/app/review/page.tsx:120`, `frontend/src/app/review/page.tsx:122`).
+- `/review` renders the main review rubric before legacy operations (`frontend/src/app/review/page.tsx:141`) and places legacy compatibility only in the later `advanced-operations` section (`frontend/src/app/review/page.tsx:394`, `frontend/src/app/review/page.tsx:400`).
+- The legacy panel copy states that the default bilingual path stays in scorecard, trace, claims, and reference sections above (`frontend/src/app/review/page.tsx:407`).
+- `frontend/src/app/lib/copy.ts:201` records that heavy scorecard, routing logic, and old packet surfaces remain secondary.
+- `frontend/src/app/lib/copy.ts:244` through `frontend/src/app/lib/copy.ts:246` describe deep review as score, trace, and evidence first, before any legacy tools.
+- `frontend/src/app/lib/copy.ts:267` through `frontend/src/app/lib/copy.ts:272` describe historical packet, delivery, and operational surfaces as compatibility, not the default review path.
+- `frontend/src/app/components/legacy-operations-panel.tsx:11` through `frontend/src/app/components/legacy-operations-panel.tsx:12` lazy-load the legacy scorecard implementation, and `frontend/src/app/components/legacy-operations-panel.tsx:49` through `frontend/src/app/components/legacy-operations-panel.tsx:71` render it only after the closed `details` drawer is opened.
+- `frontend/src/app/worlds/[worldId]/review/page.tsx:176` describes the world-scoped review as score-first, followed by runtime, explain, or report only if needed.
+- `frontend/src/app/worlds/[worldId]/review/page.tsx:233`, `frontend/src/app/worlds/[worldId]/review/page.tsx:244`, `frontend/src/app/worlds/[worldId]/review/page.tsx:254`, and `frontend/src/app/worlds/[worldId]/review/page.tsx:272` show the world-scoped order as rubric, review brief, perturbation lineage, and then follow-up entrypoints.
+- `frontend/src/app/lib/main-path-navigation.ts:28` through `frontend/src/app/lib/main-path-navigation.ts:53` keep default public navigation on world, perturb, branches, explain, and analyst mode.
+- `frontend/src/app/lib/workbench-data.ts:5`, `frontend/src/app/lib/workbench-data.ts:447`, and `frontend/src/app/lib/workbench-data.ts:448` continue reading the public compare, claims, and eval summary artifacts by logical id, while the claim types and drilldown logic keep `label` and `evidence_ids` (`frontend/src/app/lib/workbench-data.ts:10`, `frontend/src/app/lib/workbench-data.ts:11`, `frontend/src/app/lib/workbench-data.ts:493`).
+
+## Reasonable Inference
+
+- Packet-heavy and legacy surfaces still exist, but they no longer dominate the default product path. They are either downstream of the public guided demo or inside explicitly labeled compatibility sections.
+- The current branch does not need frontend code changes because the inspected routes already encode the desired containment.
+- Existing compare, evidence, and eval contracts remain preserved because this work changes no schema, scenario DSL, claim/evidence shape, run trace shape, or artifact layout.
+
+## Open Questions
+
+- TODO[verify]: future private-beta product work should keep checking that packet/export/handoff surfaces do not move back into the default navigation or first review section.
+- TODO[verify]: if a later frontend change touches runtime review, compare, evidence, eval, packet export, or handoff UI, rerun `npm run build --prefix frontend` and inspect the changed route order before merging.
+- TODO[verify]: a future browser visual pass should confirm that the closed legacy drawer does not dominate above-the-fold desktop or mobile `/review`; this report verifies source order and copy, not rendered pixel priority.
+
+## Decision
+
+No frontend code change is required for this Phase 47 item. The public and world-scoped review surfaces already keep analysis-first review ahead of compatibility tooling, and the repository can close `#369` with documentation evidence only.
+
+## Validation
+
+- `python scripts/check_no_secrets.py`
+- `python -m backend.app.cli audit-github-queue --repo YSCJRH/mirror-sim`
+- `git diff --check`
