+# Delta for multi-device-eq
+
+Existing spec: `openspec/specs/multi-device-eq/spec.md` (device-event
+resolve-and-apply, first-seen bootstrap, cold start, connect-disconnect-
+reconnect cycle, toggle-off behavior). None of that resolution logic
+changes. This delta only ADDS a requirement about where the per-station
+editing surface is reached from, and pins that the relocation has zero
+effect on resolution. Traceable to WU14 (shares WU13's editor component).
+
+## ADDED Requirements
+
+### Requirement: Per-Station EQ Entry Relocates, Resolution Logic Does Not
+
+The per-station EQ editing surface MUST be reachable from the player's
+tool tray (see `eq-custom-presets`). This relocation MUST NOT alter the
+existing 4-level resolution hierarchy (matrix -> station -> device ->
+global) or any of its resolve-and-apply, first-seen-bootstrap, cold-start,
+or connect/disconnect/reconnect behavior.
+
+#### Scenario: Editing per-station EQ from the player uses the existing hierarchy
+
+- GIVEN a station has an existing entry in `presetsMatriz` or `presetsPorEmisora`
+- WHEN the user edits it via the player's per-station EQ sheet
+- THEN the change persists through the same resolution path already covered by `multi-device-eq`'s existing tests
+- AND device-change resolve-and-apply behavior for that station is unaffected
+
+#### Scenario: Existing multi-device-eq test suite is unaffected (regression guard)
+
+- GIVEN the existing `multi-device-eq` scenarios (device-event resolve-and-apply, first-seen bootstrap, cold start, connect-disconnect-reconnect, toggle-off)
+- WHEN the per-station entry point relocates to the player
+- THEN every one of those scenarios continues to pass unmodified
