Subject: [PATCH] Fix CI classifier fixtures in PR context

The corpus workflow runs its fixture suite during pull requests. Its ambient pipeline kind caused the generic wiki-only fixture to exercise the deliberately full pull-request policy instead of the local classifier path. Pin each ordinary fixture to local while retaining explicit manual and pull-request cases.

Defense: wiki/process/agent-scale.md section 2 requires a fast corpus CI contract with change-aware Rust verification while pull-request and manual runs remain full safety gates. This keeps that stated policy testable from inside the always-on corpus workflow.

+# 2026-07-10 — Keep CI classifier fixtures independent of their pipeline
+
+```
+Type: log
+```
+
+## Intent
+
+Repair the corpus pull-request workflow after its classifier fixture inherited
+`TANGLED_PIPELINE_KIND=pull_request` and incorrectly reported that a wiki-only
+path required the Rust gate.
+
+## Changed
+
+- The ordinary wiki-only and Rust-source fixtures now explicitly select the
+  local classifier context. The manual and pull-request cases continue to
+  select their own full-safety contexts.
+- The agent-scale verification contract now records that fixture isolation.
+
+## Design/spec impact
+
+No game rule or CI policy changed. Pull requests and manual runs remain full
+Rust/Bevy safety gates; this restores the classifier regression test that
+verifies that policy from inside the always-on corpus workflow.
+
+## Checks
+
+- `TANGLED_PIPELINE_KIND=pull_request bash tools/test_ci_rust_changed.sh`
+- `./tools/check.sh --docs`
