-## 9P: everything is a file
-
-The 9P server exposes the agent runtime as a synthetic filesystem. Every session
-is a directory; every operation is a read or write. There is no client library,
-no SDK, no protocol buffer — `ollie-9p` commands are the API.
-
-```sh
-# Create a session
-echo "name=worker" | ollie-9p write session/new
-
-# Submit a prompt
-echo "fix the bug in main.go" | ollie-9p write session/{sname}/agent/{aname}/prompt
-
-# Stream the response
-ollie-9p read session/{sname}/agent/{aname}/chat
-
-# Check state
-ollie-9p read session/{sname}/agent/{aname}/state
-
-# One-shot generation (no session needed)
-echo 'explain monads' | ollie-9p rdwr generate
-
-# Route a task to the best model
-echo 'redesign the auth system' | ollie-9p rdwr route
-# → backend=kiro model=claude-sonnet-4-20250514
-```
-
-### Network transparency
-
-9P is a network protocol. Connect to a remote agent:
-
-```sh
-ollie-9p -addr tcp!server:5640 read session/idx
-```
-
-No SSH tunneling, no port forwarding, no API gateway. One connection and every
-session, every tool, every config value is accessible as if local.
-
-### Pipe `o`: a composable CLI
-
-The `o` script (`data/scripts/o`) wraps the 9P namespace into a composable CLI:
-
-```sh
-o read chat           # stream chat output
-o prompt              # interactive multi-line REPL
-o tail                # tail chat with block-marker filtering
-o readloop statewait  # block until state changes
-```
-
-Context is set once, then every command addresses the right agent:
-
-```sh
-eval $(o env mysession myagent)
-o read state      # → session/mysession/agent/myagent/state
-o prompt          # REPL for session/mysession/agent/myagent
-```
-
-Paths resolve based on context — agent files (`state`, `chat`, `prompt`, etc.)
-use `$session` + `$agent`, session files (`env`, `ctl`, `name`) use just
-`$session`, root paths (`models`, `agents`, `help`) need no context. Full
-paths starting with `session/` bypass resolution entirely.
-
-### `o tui`: an agent terminal in 20 lines of tmux
-
-`o tui` composes `o tail` and `o prompt` into a single tmux layout — no
-framework, no widgets, no IPC. It's two shell commands in two panes:
-
-```
-┌──────────────────────────────────┐
-│  o tail | grep                    │  ← chat stream
-│                                   │
-├──────────────────────────────────┤
-│  o prompt                         │  ← input REPL
-└──────────────────────────────────┘
-Agent state shown in tmux status bar
-```
-
-The prompt REPL supports multi-line input (send with `.` on its own line),
-slash commands (`/stop`, `/model`, `/quit`, etc.), and readline editing.
-Agent state updates the tmux status bar in real time via `statewait`, with
-color-coded background — green for idle, orange for calling, blue for thinking.
-
-This is the entire "frontend": two `o` subcommands, two tmux splits, one
-background `statewait` reader. No SDK, no widget toolkit, no event loop.
-It's the Plan 9 principle in miniature — shell composition over framework
-bloat.
-
-Because operations are 9P I/O, they compose with scripts:
-
-```sh
-# Fan out a prompt to all agents
-for s in $(ollie-9p read session/idx | cut -f1); do
-  for a in $(ollie-9p ls session/$s/agent | grep -v new); do
-    echo "run tests" | ollie-9p write session/$s/agent/$a/prompt
-  done
-done
-
-# Read all agent plans
-ollie-9p read session/idx | cut -f1 | while read s; do
-  ollie-9p ls session/$s/agent | grep -v new | while read a; do
-    echo "=== $s/$a ==="
-    ollie-9p read session/$s/agent/$a/plan
-  done
-done
-
-# Strip block markup from chat output (text-only frontends)
-ollie-9p read session/{sname}/agent/{aname}/chat | grep -vE '^\[\[\[.*'
-# → filters [[[type]]]/[[[end]]] block markers, leaving plain text
-```
-
-Pipe agents into `awk`. Filter with `grep`. Schedule with `cron`. Orchestrate
-with a 10-line shell script instead of a framework.
-
-### Plan 9 patterns
-
-- **`/net/dns` pattern** — `/complete`, `/generate`, `/route` are stateless
-  per-fid: write a request, read back the result
-- **`ctl` files** — control operations (stop, kill, rename, compact) are writes
-  to a control file, not method calls
-- **Blocking reads** — `statewait` blocks until state changes, replacing event
-  subscriptions with a simple `cat`
-- **Multiplexing** — multiple clients mount the same server simultaneously,
-  each with an independent view through per-fid state
-
-### KDE frontends
-
-- **Plasmoid** — embed an agent chat widget in the Plasma panel
-- **Kate plugin** — inline AI assistance in the text editor
-- **KRunner** — launch prompts from the desktop search bar
-- **Standalone GUI** — full-featured Qt6 chat application
