Macros record the command stream off the message bus rather than raw keystrokes, so replay is immune to mode and timing skew. Replay applies as a single undo group: a replay that errors mid-way rolls the buffer back to its pre-replay state instead of leaving a half-applied edit. - q + register starts recording, q stops; [N] @ + register replays with a count - Macros live in per-session a-z registers; durable cross-restart storage lands with the named-register work (issue #3) - Recording indicator in the status bar; replay failures surface as a toast with the rolled-back step - Covered by record/replay round-trip and mid-replay rollback tests
The wasm interpreter now lives in its own library, wick (github.com/ooyeku/wick), extracted from this repo. The in-tree copy is deleted; the loader, plugin CLI, and fuzz targets import the package. The integration contract is wick's docs/stem-contract.md. Every plugin call now runs under an instruction budget (CALL_FUEL_BUDGET, 50M): a runaway plugin fails that one call with OutOfFuel — logged, counted, and contained — instead of hanging the editor. Host calls cost one instruction, so slow subprocesses are not penalized. Containment is observable: the loader keeps per-plugin CallStats (calls, traps, last error, last/max fuel per call), shown in the plugin-manager dashboard JSON and report and in the control center plugin section. Plugin traps feed a new RuntimeAlerts counter, so a misbehaving plugin lights the same check-engine light as dead letters and open circuits.
Docs catch up with the release: - All references to the in-tree wasm interpreter now point at the wick package (plugins.md host-internals section rewritten with the fuel budget and CallStats; dead source link removed) - wick added to the dependency lists in README and docs/stem.md - Plugin dashboard docs describe the per-plugin call/trap/fuel stats; check-engine enumerations include plugin traps - Roadmap 0.14.0 section reflects what shipped (wick + fuel + observability, transactional macros); architecture essay closing updated to match - stem.md: project tree drops interpreter.zig, gains wasm_loader_fuzz.zig; select-mode row mentions macro keys Dead code removed, verified unreferenced: - src/ui/help_view.zig (orphan file; help.zig is the live help UI) - WasmPlugin.readWasmStr and an unused wick import alias in plugin_cli.zig (extraction leftovers)

0.14.0 is the "Deterministic Editing" release: transactional macros, a plugin host that is now a standalone library with metered, observable calls, and a docs/dead-code polish pass.
