- Add --debug[=DIR] / --profile[=DIR] flags that write run artefacts
(patterm.log, events.jsonl, per-child raw PTY captures, CPU + heap
+ goroutine pprof) to a dir without polluting stdout/stderr.
- Strengthen vendor-TUI orientation in three places (MCP
initialize.instructions, the spawn_agent tool description, and
help('spawning')) to head off codex's habits of poking the Unix
socket via perl and shelling out to launch peers — both bypass
caller identity and produce orphaned top-level tabs.
- Fix click-and-drag text selection from alt-screen TUIs. Host SGR
mouse reporting now follows the focused child's screen side
instead of being permanently armed; alt-screen TUIs that need
mouse re-enable it themselves and the toggle is forwarded.
- Move drawSidebar() off the per-PTY-chunk hot path. Long claude
session resume was paying a full sidebar rebuild for every
scrolled chunk; the chrome ticker now drains a dirty flag at 60 Hz.
- Gate the per-chunk Title() CGO poll on a containsOSC scan so
codex/ratatui's many SGR-only chunks no longer pay a CGO call each.
This batches the in-flight [Unreleased] block from CHANGELOG.md into a
single commit. Highlights:
- Real MCP protocol layer (initialize / tools/list / tools/call) so
vendor MCP clients can complete the handshake against the per-PID
socket. Legacy direct-dispatch preserved for the harness.
- New mcp_injection kinds — cli_override for codex, config_env for
opencode — joining the existing env-var and config_file paths so
patterm can slot into more agents without touching their real
config or auth.
- Ctrl+A/D and Ctrl+W/S focus navigation across tabs and intra-tab
process lists, recognised in legacy / kitty CSI u / xterm
modifyOtherKeys encodings.
- Palette macros (sw / k / sp ) and reordering so open sessions
surface above spawn-new entries.
- Two-row tab bar, sidebar/tabbar/status chrome cache, viewport-wipe
on agent spawn, CR-terminated orchestrator injections, and split-
Enter PTY writes so paste-detecting TUIs see Enter as a key event.
Also fixes the bug logged in TODO: claude's Ctrl+O tool-call expansion
emits CSI 0 J, which the viewport renderer was forwarding verbatim —
wiping the sidebar to the right of the cursor and leaving the chrome
cache convinced nothing had changed. CSI 0 J and CSI 1 J are now
translated into per-row ECH sequences clamped to the viewport, same
as CSI 2 J and CSI K already were.
Agent guides (CLAUDE.md / AGENTS.md) now spell out the
TODO->CHANGELOG workflow so completed items land in the changelog
rather than as ticked entries left behind in TODO.
