Issue 1409; design 39 parts §15 and the lead's answer D3.

Live on novox after #665's delivery: novox/node-files.list {path: /var/lib/claude-licence-manager} (and /root) answers "cannot be listed, not even through sudo: sudo -n /usr/bin/find: fork/exec /usr/bin/sudo: invalid argument". listAsRoot's and searchBelowAsRoot's find -printf formats ended in a literal NUL byte since 5d98bcc0 (2026-10-16), and exec refuses an argument holding one, so no list or search through root ever ran on a node.

Quick fix: find writes \0 itself. Thorough, in the same commit: the tests' stand-in root refuses an argument holding a NUL as exec does, so every root call in the module is held to it (it found the search's instance). No other module in the repository passes such an argument.

Tests: TestTheReadsFallBackToRoot fails with either old format. vet, vet -tags integration, unit, gofmt pass.

mesh-files: find writes the NUL itself, so a list or search through root runs at all (issue 1409)

mesh/delivery merged: source.main moved to novox/mesh-catalog@836fcd81f65b

Details

mesh/check checking c29ef0d95ea7 on 836fcd81f65b

c29ef0d95e

Live on novox 2026-11-12: node-files.list of a root-only directory answered
'fork/exec /usr/bin/sudo: invalid argument'. The kernel refuses a program
argument that holds a NUL byte, and listAsRoot's -printf format and
searchBelowAsRoot's ended in a literal \x00 since 5d98bcc0 (2026-10-16), so
no list or search through root ever ran on a node. find writes \0 itself.
The stand-in root in the tests refuses an argument holding a NUL, as exec
does, so every root call is held to it; it found the search's instance.

Builds: design 39 parts §15 and the lead's answer D3 (list through root of a place a secret is kept).
