Add before-after controls for all 64 cases and fix Vuetify navigation

Record source-derived scoring controls, complete all full-answer indexes, disclose automated review limits and explain the unchanged 530-task selection. Remove only residual navigation labels in the two already-scoped Vuetify cases; preserve frozen editions and substantive requirements.

 It does not certify the old report or establish that all similar requirements in
 the catalog have been corrected. All 64 cases have source-context review records;
 those records disclose partial observations and unavailable historical captures.
+Review here means assistant-led source inspection and automated checks, not
+independent human approval. Raw captures are external, so these checks cannot be
+replayed using the public repository alone. Independent sampling of the removals
+is still needed before formal adoption. All 64 full-answer controls are indexed
+under `current_source_reviews[].full_answer_control` in the provenance file.
 Freeze the rules and inputs before collecting outputs. Saved-answer rescoring is
 reported separately as sensitivity analysis. See the [scope and adoption requirements](definitions/annotation-revisions/primary-content-20261103.md).
 
 ### Proposed 530-task selection
 
+The selection retains the earlier 430-task edition and adds all 100 article
+tasks. It excludes both separately labeled 10-task example groups from the mixed
+webfetch suite. The dynamic examples have corresponding IDs and URLs in the
+dedicated dynamic suite, where they remain selected. The challenge examples are
+excluded as a complete additional group, not because all ten are duplicates:
+only three share a URL with another selected task. This is a report-aligned
+cohort choice documented after outcomes were available, not a claim of
+pre-outcome selection or representative sampling. The 530 selected identities
+and historical editions are unchanged.
+
 The proposed revision uses the explicit [530-task selection](definitions/populations/primary-content-20261103.json): 130 webfetch tasks and 100 each from dynamic-content, popular-sites, access-restrictions and articles. The excluded 20 webfetch entries remain in the historical frozen files. Matching dynamic-content entries remain selected under their own suite identity.
 
 After exporting a suite with the compatible exporter and `--revision primary-content-20261103`, generate its runner selection from this dataset checkout:

+All 64 revised cases now have source-derived counterfactual results in the

+edited answer fails the predecessor rules and passes the proposed rules. A
+navigation-label-only or navigation-container-only answer fails both versions.

+Independent human sampling remains outstanding.
+
+The checks exposed two residual navigation requirements within the original 64
+cases. Vuetify server-table (dynamic-034) no longer requires `Contents`, `Features`
+or `Types`. Vuetify virtual-table (dynamic-035) additionally no longer requires
+`Data tables`. Historical DOM evidence places these labels in navigation; removing
+those navigation containers leaves each serialized main subtree unchanged.
+`Data tables` remains required for the server-table case because it occurs in its
+main content. Body, table, link and record requirements remain unchanged.
+
+The review's request for change-specific controls is accepted. Its suggestion
+that there were no navigation-only controls is too broad: generic scope controls
+already existed, but did not establish the actual before/after behavior of all
+64 cases. These additional records address that narrower evidence gap.
+Comparable unrevised cases and full-population runner binding remain separate,
+unresolved review items; this update does not claim to resolve them.
