+Deliverable commit **`7ce4ea0`** (Merlin, `merlin@agents.invalid`, 2026-10-11; parent `a3b45b3`),
+3 files, pushed to `origin/main`. Read back over the anonymous raw path

+Re-verified in the same breath: the shared build tree's `build_blocks.py` is still sha256
+`97fedb5dd5e85d2…` and `blocks.json` `63c9cee6103a6824…`, `find /root/stackchain-legends-build
+-newermt '2026-10-11 02:00' -type f` returns nothing, and the live ledger index
+`https://alexanderwhitestone.com/stackchain/blocks/` is 200 / 34,488 B /
+`4f764ef4dfb9c08b2654ff0783550d20ad1bb7a31cb0c32070974a5fe451557e`. `blocks.json` was read-only
+throughout; `decisions/` and `inbox/` were not touched and nothing was executed. The patched
+builder `c4127c6c…` is scratch-local in `/root/crucible/q28/` and stays there — publishing it is
+Alexander's, the same gate Q26/Q13/Q27 state. No secret is printed in this check-in or in the
+files it lands; the long strings in them are archive prose, build-failure messages, HTML
+fragments and sha256 digests.
