Refactor panes and filesystem; replace FUSE with 9P

2026-09-07T16:59:12Z

Consolidate pane, layout, memory and host code. Serve 9P by default over Unix sockets, with runtime mounts and optional TCP/QUIC transports. Remove FUSE and obsolete proof-of-concept examples. Fix highlighting and terminal-history performance, expand differential and stress-test infrastructure, sort navigation results while preserving the next occurrence, add syntax-colored Braille minimaps, remove SPC-k, and document 9P interaction as a repository skill.

pipe: helix's other three shell commands, and its newline rule

2026-09-03T19:28:12Z

`|` was the only one of helix's five. The other four differ in exactly two things — whether the selection is stdin, and where the output lands — so they are one action carrying a `PipeBehavior` rather than four code paths: | stdin is the selection, output REPLACES it (had this) A-| stdin is the selection, output discarded shell_pipe_to ! no stdin, output inserted BEFORE each selection shell_insert_output A-! no stdin, output appended AFTER each selection shell_append_output Each arms the same visible tag-tail prompt with its own marker (`|`, `|-`, `!`, `!+`) so the prompt says which one you are in — they take the same command line and do very different things to the buffer. Two helix rules came with them. A behaviour that sends no stdin runs the command ONCE and every cursor gets that one answer (helix's `shell_output` cache): ten cursors and `date` give ten identical stamps rather than ten forks racing to produce one. And a command that put a trailing newline on a selection which did not have one has it taken back off — that is what keeps a one-line `| tr a-z A-Z` from becoming two lines. The existing multi-range test moved with that rule and now pins it deliberately. In all three writing behaviours the OUTPUT is what ends up selected, keeping the original range's direction, so an operator can follow straight on from what the command just produced. `$` (`shell_keep_pipe` — drop the selections whose command exited nonzero) is still missing: it needs a per-selection verdict and the runner's answer is atomic. Noted in docs/helix-keys.md beside the `$` divergence already there. Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_016Q4RATpafkwahrovHQLKRf
