+## Orchestrator verification (2026-10-18)
+
+**Confirmed: visual injection works.** `posthandler_persist_3600.png` shows a
+black 64x64 box on the live Terminal Manager's Memory bar while the OS is
+running — root weave rendered, "TCP/IP is now up.", the Messages pane logging
+"Debug connection from IP host 192.168.99.1" twice, memory figure 3099 KB.
+That is injected code drawing into a live OS, not a frozen frame.
+
+**Not confirmed: the blink.** The 3450/3480/3500 on/off/on frames cannot be the
+programmed toggle:
+
+* `blink.asm` toggles state every `0600h` = 1536 display interrupts.
+* the counter at `0186F000` advances about once per emulated frame
+  (10 -> 793 over frames 3524 -> 4227 in `blink_resident_client.log`), so the
+  toggle period is ~1536 frames (~21 s), not the 30 frames between the crops.
+* the run the summary attributes to the blink used `blink.bin` (172 B), whose
+  counter kept incrementing — the hook ran every interrupt, and the stock
+  handler repaints after it, so frame-to-frame on/off is a repaint race.
+* the payload meant to draw *after* the handler (`blinkev.bin`) draws once and
+  then loses the TCP stack (`blink_repeat_client.log`: challenge, timeout,
+  "No route to host").
+
+So the durable result is a **persistent box**, and the hook demonstrably runs
+every frame, but a **controlled blink is not established**. Settling it needs a
+time series spanning >1536 frames around a known counter value, or hooking the
+display work path (`3F579880`) rather than the vector.
