 - Done (17 Oct): the 16 Oct sweep's backlog. Relays and lights answer their inputs and a zero-delay wire loop stops (#1209, #1218); each level fires through its own dispatcher (#1211); doors open the Quake way with every leaf (#1210, #1217); the navmesh runs through doors and around props (#1196, #1197, #1239); Bake Changed and Bake Selected see entity data, ties, paint and their own earlier output (#1198, #1199, #1208); cordons, the spawn check and the game export agree (#1204-#1207); cuts and Merge keep a brush entity whole and Merge builds a convex solid (#1194, #1200, #1251); Validate measures generated stairs and the player holds to its 0.4 m step (#1212, #1215, #1216). Every palette action now runs in CI through the real plugin in ten edge states (#1261).
 - Done (18 Oct): structures updated and detached by `generator_id` (#1302) and prefabs placed from the library (#1301), both through `hf_run_command`; a prefab copy placed turned, or rebuilt by a variant switch or propagate, turns its doors' move angle and its spawn's yaw with it (#1312); a redone Detach leaves no structure or array tag on the old pieces, and a copy that seeded an array of its own still reaches its own array (#1306, #1309). Cordons on the bridge (#1300): `hf_get_cordons` lists them, `hf_set_cordon` adds one round brushes or at a box, or moves, names or switches one by index, and `hf_remove_cordon` takes one out, each one undo step that holds the cordons, which no level state does, so a refused or undone `hf_batch` puts them back with the rest. The dock is told of every edit. `hf_bake` with `cordons: true` bakes only what they take, into the same file, and says so in its answer, the file's metadata and `last_bake` (#1317).
 - Done (21 Oct): floor paint on the bridge (#1299). The paint system has calls in cell space, with no screen or mouse in them: a rectangle of cells painted or erased on a layer, the walls of its painted cells raised to a height, a room stamped from a corner and a size, and the connector between two layers confirmed where their painted cells meet, each rebuilding the chunks it touched. Four Paint entries carry them as bridge forms, `paint_ramp`, `paint_raise`, `paint_room` and `paint_confirm_connector`, taking a layer by index or name and cells as `[x, z]`, each one `MCP: ...` step that `hf_undo` takes back and an `hf_batch` op; `hf_list_commands` lists the level's layers beside them. The Rect stroke, the room stamp and the ghost confirm share the rectangle and the confirm with the bridge, so there is one of each.
+- Done (21 Oct, sweep): `hf_set_spawn` turns the marker with the yaw it writes, and `hf_undo` puts both back (#1295); a whole bake stays current across `hf_set_cordon`, `hf_remove_cordon` and their undo and redo (#1319); `hf_set_spawn` and `hf_validate` judge the spawn by the whole level and warn when a bake cut to the cordons would leave it floating, as does `hf_bake` with `cordons: true` (#1321); the cuts `hf_bake` applies are the agent's own step, so `hf_undo` takes them back (#1353); one field rule for params, structure settings and generator creates, with an enum by index or label in any case (#1341); the batch ops built from one list and checked against the dispatcher's (#1342); the guide shows the Agent Bridge panel with an agent connected (#1335).
 - Next: what the not-yet list above names.
