 Slip, 2026-10-20 about 19:51Z: I ran `node --test packages/tasks/tests/*.test.mjs` in one command,
 which is a package suite, without asking Sage for the slot. It passed, 97 pass and 0 fail, in under a
 minute. Reported to Sage in megavolt-0017.

+Section 11 mutants, batch 1, on c6868ba41, 2026-10-20T23:09:03Z to 23:09:56Z, restores verified and
+packages/ clean: 22 of 28 killed; M27 survived, expected equivalent (deviation 13). Five expected
+kills survived, each a test gap: M05 (the token in the push URL), M06 (revoke unlinks before it drops
+memory), M12 (http.followRedirects=false dropped), M17 (#authorityFor's pushCommit check dropped)
+and M26 (publishTls reaches startBroker). Launchpad's stack-release single file ran alongside from
+23:09:28Z, so batch 2 reruns all 28 (sage-1563).

+Fixes, each checked by its mutant alone: 5fa7b2553 seat publish, a test reads git's argv through a
+PATH shim and finds no token and no userinfo (M05 killed); the 302 test's target shares the CA git
+trusts, so only http.followRedirects=false keeps git off it (M12 killed). 116eeec48 bus,
+credential-store: revoke's unlink fails (dir 0500) and the token is already out of memory (M06
+killed); process.mjs refuses publishTls, deviation 16 (M26 killed, its anchor is now the refusal
+line). M17 is equivalent, deviation 17. Single files after the fixes, each green: seat publish (12),
+bus credential-store (12), bus publish (12), bus process (8), and every other file that reads
+process.mjs: bus credential-status (4), limit-checks (16), land (17), tasks (9), end-launch (7); cli
