agent: repoint roles to frank-medium/dankclaw-3090; sync niri tweaks, memories, managed skills

- config.yml: default/commit -> frank-medium (dankserver); task/tiny/smol/vision -> frank-small (dankclaw-3090); vision xhigh
- models.yml: add llamacpp (dankclaw-3090) provider; frank-large preserve_thinking + context notes
- niri: focus-ring/border/shadow layout, hot-corners off, re-add noctalia.kdl include; blankpad eDP-1 scale 1.0
- memories: flush rollouts; retire frank_large + marreta_authentik skills; add auth-chain/kv-pool/quadlet-log skills
- managed-skills: 40+ new fleet runbook skills
- agent/skills: import built-in skill set

+name: niri-output-rotation-pinning
+description: "Rotate/re-arrange niri monitors (portrait transforms, positions, scale) persistently and verify — covers the output-block-resets-defaults trap and auto-layout reflow that flings unpinned outputs, plus the counter-clockwise transform convention."

+
+# Rotating and pinning outputs on niri
+
+Verified on blankpad, niri 26.04, 2026-09-15 (two PM1601 externals + eDP-1 laptop panel).
+
+## 0. Ground truth first
+
+```bash
+niri msg outputs            # connector names, current mode, scale, transform, logical pos/size
+niri --version
+```
+
+Niri output **names are connector names** (`eDP-1`, `DP-2`, `HDMI-A-1`), not EDID model strings. The EDID strings printed before them in `niri msg outputs` are decoration — use the parenthesized name.
+
+On blankpad the live config is split by `include "./cfg/*.kdl"` from `~/.config/niri/config.kdl`, and `cfg/display.kdl` is a **symlink into the dotfiles repo** (`~/.omp/dotfiles/zz-blankpad/niri/.config/niri/cfg/display.kdl`). Edit the repo path, not the symlink target path — they are the same file, but the repo path is the one that gets committed. Check with `ls -ld`.
+
+## 1. Transform direction is counter-clockwise
+
+```bash
+niri msg output <NAME> transform --help   # "Transform to set, counter-clockwise"
+```
+
+| value | effect |
+|---|---|
+| `90` | content rotated 90° CCW ⇒ the panel's **top bezel sits on the LEFT** |
+| `270` | top bezel on the RIGHT |
+| `180` | upside down |
+| `flipped-90` / `flipped-270` | mirrored variants |
+
+`90` vs `270` is a physical-stand fact no tool can read (portable monitors expose no orientation in EDID/MCCS). Pick one, apply it, and give the user the one-liner to flip — don't stall on the question.
+
+## 2. Two traps that bite when you edit the config
+
+1. **An `output "X" { … }` block resets every property you don't restate to its default.** Pinning position on `eDP-1` without repeating `scale 1.25` silently drops the laptop panel to scale 1.0. Restate `scale` (and `mode` if you care) in every block you touch.
+2. **Niri re-runs auto-layout for outputs with no pinned position.** Pinning only the externals shoved `eDP-1` from `0,0` to `3936,0` (laptop became rightmost). If you want the pre-existing left-to-right order, pin every output's position.
+
+Positions are logical pixels at each output's own scale. Original order preserved example:
+
+```kdl
+output "DP-2" {
+    scale 1
+    transform "90"
+    position x=1536 y=0
+}
+
+output "HDMI-A-1" {
+    scale 1
+    transform "90"
+    position x=2736 y=0
+}
+
+output "eDP-1" {
+    scale 1.25          // MUST restate: dashed-out by the block otherwise
+    position x=0 y=0
+}
+```
+
+x-offsets chain: `eDP-1` logical width 1536 → DP-2 at 1536 → +1200 (portrait width) → HDMI-A-1 at 2736.
+
+## 3. Apply and verify
+
+```bash
+niri validate -c ~/.config/niri/config.kdl          # exit 0, "config is valid"
+niri msg action load-config-file                    # live reload; load-config-file, NOT reload-config
+sleep 1
+niri msg outputs | grep -E '^Output|Transform|Logical|Scale'
+```
+
+Success looks like `Logical size: 1200x1920` (swapped) plus `Transform: 90° counter-clockwise` on each rotated panel, with positions matching the intended chain.
+
+One-off rotation without touching config (temporary, forgotten on next config change):
+
+```bash
+niri msg output DP-2 transform 90
+```
+
+## 4. Commit
+
+Dotfiles repo is `dank/command-center` (`main`); push to the local Gitea is permitted.
+
+```bash
+cd ~/.omp && git pull --ff-only
+git add dotfiles/zz-blankpad/niri/.config/niri/cfg/display.kdl
+git commit -m "blankpad(niri): <what changed>"
+git push
+```
+
+## Pitfalls
+
+- `reload-config` is not a niri subcommand — it's `niri msg action load-config-file`.
+- Never SIGUSR1 a terminal to "reload"; niri config reloads do not touch ghostty themes.
+- No man page for niri on this host; `niri <sub> --help` and `/usr/share/doc/niri/default-config.kdl` are the docs.
