+Both `pr-review.sh` and `issue-comment.sh` accept an optional `--login <name>` flag that overrides the automatically detected Gitea login for that single invocation (as of #1280, `pr-create.sh`, `pr-merge.sh` and `issue-create.sh` accept it too, and it wins over `MOSAIC_GIT_IDENTITY` everywhere).

 As a durable successor to this mechanism, consider giving each reviewer/approver slot its own dedicated Gitea login credential, so that author≠reviewer holds at the credential level rather than relying on wrapper-level `--login` bookkeeping. This is a recommendation for future hardening, not something implemented by this flag.

+### Identity-first principal resolution in the wrappers (#1280)
+
+`resolve_gitea_principal()` (detect-platform.sh) gives the write wrappers —
+`pr-create.sh`, `pr-merge.sh`, `pr-review.sh`, `issue-create.sh`, `issue-comment.sh` —
+ONE precedence for choosing the acting principal:
+
+1. an explicit `--login <name>` (now accepted by all five; operator intent beats
+   environment), then
+2. the per-agent identity above (`MOSAIC_GIT_IDENTITY` env / worktree
+   `mosaic.gitIdentity`) when a per-slot token exists — the wrapper then writes via the
+   REST API with that identity's token and never consults `tea`, so the tea login list
+   cannot shadow the requested principal, then
+3. the tea login list — the LAST resort, never the first, because it enumerates
+   whatever logins the host happens to hold and knows nothing about which seat is
+   calling.
+
+A requested identity whose per-slot token is absent, or a `--login` whose token cannot
+resolve host-bound, **fails loud** (nonzero, naming the identity/login and the expected
+slot) instead of silently writing under whatever account `tea` has configured — that
+silent fallthrough is defect #1280 (reviews, comments, merges, PRs and issues filed
+under the wrong account). `pr-merge.sh --dry-run` reports the principal the merge would
+act as, resolved exactly as the real merge resolves it. ⚠ A **workstation-global**
+`mosaic.gitIdentity` shadows every seat on that host (a fresh clone with no local value
+resolves the global one) — set it per-worktree, not with `--global`.
+
+The resolver is covered by `test-gitea-principal-resolution.sh`; the happy-path
+ordering (identity arm REACHED, not sitting behind a tea failure) by
+`test-pr-create-identity-first.sh`; merge credential binding by
+`test-pr-merge-principal-resolution.sh`.

+#      the identity's per-slot token (asserted by sentinel value AT the fake
+#      provider), and tea's `pr create` is NEVER invoked.
+#   2. identity set + slot ABSENT -> nonzero, stderr naming the identity and
+#      the expected slot path; neither tea `pr create` nor any API request
+#      fires. No silent fallback to the tea login list.
+#   3. identity set + --login -> --login wins: tea runs WITH the explicit

+#      git config mosaic.gitIdentity > shared host credential. (The pre-#1280

+#   3. The real merge POST carries the resolved principal's credential and no
+#      other: --login merges with that login's tea-config token; an identity
+#      merges with the per-slot token; an unresolvable --login never reaches
