+## r2 rebase (sage-3579)
+
+Sage ruled that 286 now goes before 258, because 222 is its only after row. Branch ludwig/row286-r2
+rebases b9506b352 (base 94c33a43c) onto origin/refactor 45dca69f6. The rebase had no conflicts.
+
+- Range-diff 94c33a43c..b9506b352 against 45dca69f6..r2: all 11 commits are `=`, so no patch
+  changed.
+- Rows 254 (331597709) and 268 (c27207f6e) were already in the old base 94c33a43c. Between the two
+  bases nothing changed under packages/library.
+- Paths the two test files import or read, diffed 94c33a43c..45dca69f6: bus broker.mjs, runtime.mjs
+  and store.mjs changed. None of the others changed: library/*, bus credentials, gitea-grant,
+  mapping, mirror, reader, survey, sync, the fake-gitea-api, helpers and host-fixtures modules,
+  business helpers (rolesCopy, systemFor), project git, seat checkout and fake-gitea, and roles/.
+  - broker.mjs: the constructor gains `accessStamp` and `compactions`, both defaulting to null, and
+    my tests pass neither. No base hunk falls in the fire job, the revoke job or the instance.fire
+    verb. Old :4308/:4335 are now :4852/:4879, with the same text. The new console-cap check refuses
+    a non-console session only on CONSOLE_VERBS, and the library verbs are not among them. The
+    request path's access re-read applies only to `s.user` sessions, and my tests open none.
+  - runtime.mjs: consoleOwners (default []), the access timer, compactions and the session-clear
+    hooks. The Credentials and giteaStart wiring that T9 uses is unchanged.
+  - store.mjs: schema 3l to 3n (row 206 thread_shares, row 271 session_ops and message_cancels).
+    Each test opens a fresh Store, and none pins a schema version or step count.
+- Hash pins: no test or script line pairs a 64-hex value with a path I change. The positive
+  control finds 64-hex pins in, for example, account-migration.test.mjs.
+- Row 285 has not landed. roles/chief-of-staff.json at 45dca69f6 still names no gitea credential,
+  so T9 keeps its scratch roles copy (sage-2947).
+- sage-3589 freezes stack-release.sh, webui-service.sh, bus-service.sh, stack-copy.sh and common.sh.
+  This row changes none of them.
+- Still to run, on CLEAR: library and bus whole, every scripts/test-*.sh, M1 and M2, and the token
+  search, all on r2.
