 - The drift 0fa7bf421..23c3d6218 (205 and 268, 24 files) meets 194 at two paths, broker.mjs and business.test.mjs. For both files, the +/- lines of 194's own diff are identical on the old and new bases. So 194's hunks are unchanged, and git applied them without touching 205's or 268's lines.
 - Whether the merged files run together is a matter for Honker's runs on b14, which Sage is gating.

+## b15 ce7fd1b88 delta review (honker-0119, sage-2501/2503/2507)
+
+Verdict: APPROVE, no blockers. These are git reads only, and nothing has run on b15.
+- b15 is b14 b565e589b plus two commits.
+- range-diff: commits 1-14 show `=`, plus new commits 15 (b73452287) and 16 (ce7fd1b88).
+- The series patch-id is 64303253f8e6. The path list is the same as b14's.
+- Neither new commit has an attribution line.
+
+(a) b73452287, broker.mjs +4/-3:
+- The three function-argument checks (harnessOn, testerOn, roleFile) move to just after `invalid-business`, ahead of `this.#store` and every store read. Each check's text is unchanged. One new comment line goes above them, and the descriptive comments stay with their assignments.
+- Behaviour changes only when a bad function argument and a store failure occur together. The argument error now wins, and that is what T8b expects (chief-of-staff.test:868, `store: null`).
+- The only other pin on these messages is routes-verb.test:89, which uses a real store and is unaffected.
+
+(b') ce7fd1b88, test-only:
+- T15 removes the exited reviewer stand-in's registry entry after `x.exited === 143`.
+- The refusal it avoids comes from business/src/launch.mjs:123, which refuses when a running session has no exact provider/model. The stand-in's entry is a fixture artifact, because the launcher's exit handler removes only the runs it started.
+- This is the same convention as N6 at lifecycle.test:763-764. standIn is unchanged.
+- I accept Sage's ruling of (b') over (b). Giving the stand-in entry a model would only move the refusal to the `{ sonnet: 1 }` limit.
+- The second remove in standIn's t.after is a no-op.
+
+N1, non-blocking: no test pins the `testerOn must be a function` message. This is old, not new in b15.
