When a user first writes to <project>/working/<email>/, the auto-own
.zddc EnsureCanonicalAncestors seeds at that folder now sets
acl.inherit: false in addition to the rwcda grant. This makes each
user's working subtree private by default — ancestor cascade grants
(e.g. a permissive *: r at the project root) no longer let anyone
read everyone else's drafts.
Implements the user-stated sandbox model: "no automatic or default
permissions other than the user's default folder which is instantiated
on first save — users can edit the .zddc files in their subtree to
allow access to others." The owner can edit
<project>/working/<email>/.zddc to add collaborators (or set
inherit: true, or list specific email patterns).
Mechanics:
- new WriteAutoOwnZddcFenced — same shape as WriteAutoOwnZddc plus
acl.inherit: false. Existing WriteAutoOwnZddc unchanged.
- autoOwnDepthMatch returns (autoOwn, fenced); idx 2 under working/
triggers fenced=true. The other auto-own positions
(depth 1: working/staging/, depth 3: archive/<party>/incoming/)
stay unfenced — those are shared lanes where ancestor admin
grants should still apply.
- staging/ children stay unfenced because staging folders are
date+tracking-named (shared lane), not per-user.
Tests:
- TestEnsureCanonicalAncestors_LazyCreation now asserts the fenced
.zddc exists at working/<email>/ with inherit: false.
- TestEnsureCanonicalAncestors_StagingChildNotFenced new — staging
children stay plain.
