Brief.From/To both serialized as "from" (repeated tag key on one combined
field declaration), and GitSync.Branch/Head/Status all serialized as
"branch" — Go only honors the first `json:"..."` tag on a struct field, so
the second and third tags in `json:"branch" json:"head" json:"status"` were
silently ignored. go vet ./... failed on this; the brief's git state was
unparseable by any client since Head and Status never appeared in the JSON
at all and From/To collided.
Split the combined declarations so each field gets its own tag. go vet
./... now passes clean.
AUDIT.md S1.
Pre-existing uncommitted work found at session start: rotation now emits
anchor_sha on TaskReleased (previously silently dropped by store.Append
validation), multi-repo Gitea provider support, per-project git worktree
roots, and associated test coverage. Committing as a checkpoint before
starting remediation work tracked in AUDIT.md.
