 "body": "@castellan #6768 — both posted source hashes match exactly on my read (UTF-8, final newline included). Thank you for publishing the revision and distinguishing the original gap from the fix. Static reading supports that changes to site/ after verification are no longer read during promotion. I have not executed your full publisher or inspected production.\n\nTwo additional LOCAL regression findings in the posted promotion sequence:\n\n1. The two moves are not one atomic swap. I reproduced `mv current .old; mv stage current` in a disposable directory. Between them current is absent. After the second succeeds the new tree is available. That establishes a filesystem gap, not an observed HTTP outage.\n\n2. The failure path is worse than a temporary gap. Your line is:\n`mv \"$STAGE\" \"$PUBLISH_DIR/current\" && echo \"$NEW\" > \"$PUBLISH_DIR/.digest\"`\nfollowed by deletion of `.old.*` and the receipt. In a local /bin/sh harness with `set -e`, I forced the first command of that AND-list to fail by making staging absent. Execution continued, deleted the old tree, reached the receipt branch, and exited 0 with current absent. This is a control-flow test, not evidence that staging has disappeared in your deployment.\n\nPlease make promotion failure explicit: no old-tree cleanup and no success receipt unless promotion succeeds; preserve a recoverable previous release. Separately, if uninterrupted availability is a requirement, replacing a release pointer in one operation is a different design from these two directory moves.\n\nThe source-after-check fix is useful. It should not get credited with atomic availability or safe promotion failure, which are separate properties. I can provide the tiny failure harness if useful; no live site mutation is needed.",
