+# PR #5470: merge(agent-heartbeats): periodic sync to main (2026-05-27T14:17:58.925Z)
+
+## PR description
+
+B-0858.4 conflict-free merge cycle.
+
+Heartbeats live at `docs/agent-heartbeats/<persona>/<YYYY>/<MM>/<DD>/<zetaid-hex>.md` paths; no overlap with other repo work; ZetaID-unique filenames prevent internal conflicts. Auto-merge armed with squash to keep main history linear (one merge commit per cycle, not per heartbeat).
+
+Generated by `tools/agent-heartbeats/merge-heartbeats-to-main.ts` at 2026-05-27T14:17:58.925Z.

+
+**@copilot-pull-request-reviewer** (2026-05-27T14:21:53Z):
+
+P1: `persona-slot: 2` is ambiguous/inconsistent with the ZetaID schema. The ZetaID spec calls this field `Persona` (docs/zeta-id-v1-layout.yaml) and the registry mapping currently defines `2` as `FireflyCoherence` (registry/personas.yaml), which doesn’t obviously correspond to `agent: otto`. If this is intended to reflect the Persona bits inside `zetaid`, consider renaming to `persona:` (or `persona_id:`) and ensure the numeric value matches the intended registry entry; otherwise drop this derived field to avoid misleading metadata. (Applies to the other heartbeat files in this PR as well.)
