The two halves

sl0ppij (sl0ppij/) is a fork of zellij. Everything it adds is in commits prefixed sl0p:. The parts that matter for integration:

OSC 5577 — a private escape sequence a pane can emit to draw a status bar in its own zellij frame, including clickable buttons whose clicks are reported back on the pane's stdin. Spec: sl0ppij/sl0p/pane-status-bar.md.
Workspace hints — panes and tabs carry a purpose= string so tooling can find "the agent pane" vs "the logs pane". Spec: sl0ppij/sl0p/workspace-hints-proposal.md.
zj-pane-finder — a fuzzy pane finder plugin (wasm), in-tree at sl0ppij/sl0p/zj-pane-finder/, deliberately its own cargo workspace so its size-optimised profile applies.

sl0pstatus (sl0pstatus/) is a fork of zjstatus, the status bar the default layout uses in place of zellij's stock tab-bar + status-bar. It is a separate wasm plugin built against the released zellij-tile, not part of the sl0ppij workspace.

pi-ext (pi-ext/) is the other end of that protocol: TypeScript extensions loaded by pi. Five of them speak OSC 5577 (answer-picker, last-prompt, sl0p-footer, slop-tool-boxes, user-prompt-frame).

Neither half is much use without the other, which is the entire argument for this monorepo: the protocol is the product, and it needs to be versioned and shipped as one thing.

What the repo holds

path	role
`sl0ppij/`	the fork. Self-contained: rebases against upstream zellij happen here.
`sl0pstatus/`	forked `zjstatus` status bar (wasm plugin) the default layout depends on.
`pi-ext/`	pi extensions + `pir` CLI helper.
`config/`	the opinionated default environment (keybinds, layouts, themes).
`packaging/`	turn the above into a tarball someone else can install.
`docs/`	this.
`FORKS.md`	what upstream everything is based on.
`VERSION`	the single sl0ppi version.

Deliberate non-goals (for now)

Not shipping a forked pi. pi is pinned and redistributed unmodified.
Not supporting anything but x86_64-unknown-linux-gnu/musl.
No CI. Releases are cut from a dev box until the rest works.
