Orion vault — clean initial history

Browse source 
Knowledge vault (Orion/PARA) migrated from the pre-Orion 484vault on
2026-10-01. Deliberately orphaned: prior history contained a plaintext
password and stays local-only on branch archive/pre-boilerplate-history.
Secrets and live Hermes state are gitignored.

# Vizio E3D470VX "no signal" on laptop — force 1080p60 mode
**Symptom:** Vizio E3D470VX TV shows "no signal" when connected to the Framework laptop; link flaps ~4x then dies. Same TV works fine on other PCs (friend's Debian and Pop!_OS machines) → mode-negotiation failure on this laptop, not card/cable/TV.
**Diagnosis path:**
1. Cross-test the TV on another machine — if it works there, rule out cable/TV/HDMI card.
2. Compare with the Epson projector case: same class of problem (display advertises/needs a mode the laptop doesn't settle on). See [[monitor-not-detected-framework-hdmi-card-latch]] for the *other* display failure mode (card latch — kernel shows disconnected).
**Fix (applied 2026-09-16):** rule in `~/.config/hypr/monitors.lua` (outside the hyprmoncfg wake block):
```lua
hl.monitor({ output = "desc:VIZIO", mode = "1920x1080@59.94", position = "auto", scale = 1 })
```
`hyprctl reload` clean. Next plug-in should auto-force the safe mode.
**If "no signal" persists AFTER this rule:** the mode-rejection theory is wrong — investigate HDCP or i915 DP-to-HDMI dongle signaling instead.
**Hermes-system note:** Mnemosyne scrubs resolution strings like `1920x1080` as IP addresses when storing memories — write them with spaces (e.g. `1920 x 1080`) in memory content.
