The web command row renders `title · summary` from one logged command lifecycle pair, and the two halves were written without knowing about each other: the title was the dispatched line rebuilt from `command/run` and the summary was `command/done`'s verbatim text, so every Access-chip pick read `/permission workspace-write · Permission preset: workspace-write.` — the command name twice and its argument twice. The title is now the bare command name (no `/`, no arguments — the summary already says what the command did), and a command handler's settlement text never repeats the command's own name, so `/permission` returns `preset workspace-write`. The row reads `permission · preset workspace-write`, and the TUI notice still names the preset that now applies. The log is unchanged: `command/run` keeps its structured name/args split for a richer registered row.

User-facing permission presets through ctx.permission (PermissionService). Each configured name bundles sandbox/mode with approval/policy; the defaults are workspace-write (workspace-write + ask) and danger-full-access (danger-full-access + never). UI adapters may expose the table as one selector, while sandbox execution and approval continue to consume their own knobs.
set(session, name) records a changed selection in a log-only permission/preset event, then calls each knob's setter only when its effective value changes. The selection event precedes the knob events and preserves user intent when presets share a bundle; a net-zero selection appends nothing. current(events) prefers a still-matching recorded selection, then the first matching table entry, and otherwise returns custom. Clients may display custom as the current value, but cannot select it.
The service requires a confining ctx.bash executor and ctx.approval. A table entry named custom throws at load; composition defaults outside the table instead make a zero-event session derive custom. See the sandbox switching design.
Two optional children ship the product surfaces over the same service: a permissions session-projection unit (src/types.ts declares the key; the unit folds the three whole-value knob events and views the select — table options plus a current-only custom — over the composition defaults) and the /permission command (bare invocation reports the current preset and the table; a preset argument switches through set). Each child activates only when its registry (ctx.sessionProjections / ctx.commands) is composed.
Model Experience
Indirectly, through dsh-user-approval and dsh-tool-bash, which render the approval-policy prompt, switch notice, and sandboxed tool outcomes selected by this service's knob events; permission/preset itself is log-only.
KV Cache effect
No direct invalidation; the named consumer owns any request-prefix changes.
Known Limitations and Deferred Work
- Only two mechanism knobs are bundled — presets select sandbox mode and approval policy; an agent/profile choice is not part of
PresetSpecyet. customis derived-only — callers can switch away from an unmatched knob combination but cannot target or persist a named custom preset through this service.- The preset table is process-level — configuration is fixed for the plugin lifetime; changing available presets requires reloading the plugin.
