+  source line or message → non-empty diff: `1172` (foreign-symbol-conflict), `1174`
+  (foreign-postfix-conflict), `1620` (cimport-foreign-ref-unvalidated).
+- **The equivalence test** `1228` (needs both `#foreign` + `extern` twins by design).
+- **Identity-`#foreign` feature tests** (filename `ffi-foreign-*`, defer rename/dedup
+  to Phase 8): `1205`/`1207`/`1216`/`1218`/`1219`.

-- **Phase 7** (`refactor` batches, snapshot diff must be EMPTY per batch): migrate the
-  corpus + issue repros. Batches (PLAN-EXTERN-EXPORT Phase 7): 7.1 `examples/12xx-ffi-*`
-  (plain C), 7.2 `examples/13xx-ffi-objc-*`, 7.3 `examples/14xx-ffi-jni-*`, 7.4
-  `issues/*` repros + stragglers. ⚠ Same shape rules as Phase 6: fn/global markers →
-  `extern …` (blanket keyword swap is safe for fn-only files); runtime classes →
-  postfix (`#objc_class/#jni_class("X") extern {` import, `… export {` defined). Check
-  each file's shapes first. Most examples ARE marker'd → the corpus validates the empty
-  snapshot diff directly; a non-empty diff ⇒ STOP and coalesce, don't regen.
-  - **Decision needed for 7.4:** the `issues/*.md` writeups contain `#foreign` in prose
-    repros — Decision 6 (historical carve-out, STILL OPEN) governs whether those get
-    migrated or kept as provenance. Migrate `issues/*.sx` repros (live tree); defer the
-    `.md` prose pending Decision 6. Also: some examples are diagnostic tests that
-    deliberately reference `#foreign` (e.g. 1174 foreign-postfix-conflict, 1620 lib-ref)
-    — those must KEEP `#foreign` until the Phase 8 cutover (they test the keyword's
-    behavior). Identify and exclude them from the 7.x bulk rename.
+- **Phase 7.2** (`refactor`, snapshot diff must be EMPTY): migrate `examples/13xx-ffi-objc-*`.
+  ⚠ 13xx has Obj-C **runtime classes** — use the postfix shape (`#objc_class("X") extern {`
+  import == old `#foreign #objc_class`; `… export {` defined == bare `#objc_class`). Check
+  each file's shapes first (`grep -c '#foreign #'`). Apply the keep-list: exclude any 13xx
+  whose snapshot asserts on `#foreign` text or whose identity is the keyword (scan
+  `examples/expected/13*.std{err,out}` for "foreign" first, like 7.1 did). Most 13xx ARE
+  marker'd (50 found in Phase 6.4) → corpus validates the empty diff directly.
+- **Remaining Phase 7 batches:** 7.3 `examples/14xx-ffi-jni-*` (JNI runtime classes,
+  same postfix rules), 7.4 `issues/*.sx` repros + stragglers (16xx platform examples,
+  the scattered 04/06/07/10 ones). For 7.4 `issues/*.md` prose: defer per Decision 6
+  (recommended = keep as provenance).
+- **Decision 6 (STILL OPEN)** governs the `issues/*.md` + comment-prose carve-out — the
+  recommended default (keep provenance, gate only the live tree) is being applied; flag
+  to the user before Phase 9 if not yet ratified.
