FCSIT — five per-pane toggles

Each pane in the workspace carries five feature switches: Filter, Cache, Secrets, Indexer, Terse. Set per-pane; persist to ~/.senkani/panes/{paneId}.env; take effect immediately without a restart.

What it does

Filter

Filter pipeline — 24 command-specific output rules applied to senkani_exec.

Cache

Read cache — keyed on (path, mtime); unchanged files return from memory.

Secrets

SecretDetector — 14 regex families + entropy fallback on every tool output.

Indexer

Symbol indexer — senkani_search, senkani_fetch, senkani_outline active.

Terse

off

Terse mode — output-token reduction via system-prompt injection + phrase strip.

How to toggle

UI: click any letter in the pane header — opens that pane's settings panel, where each toggle sits next to a one-line description and a Learn more → link to the per-pane optimizers concept page. The header letter highlights when on; toggling lives inside the panel.
Env var: SENKANI_FILTER=on|off, SENKANI_CACHE=on|off, SENKANI_SECRETS=on|off, SENKANI_INDEXER=on|off, SENKANI_TERSE=on|off.
MCP: senkani_session with action:"toggle", feature:"filter".

Per-pane vs global

FCSIT is per-pane. Different panes can run different combinations — a terse-mode research pane alongside a full-fidelity build pane. Global defaults come from ~/.senkani/config.json; env vars override per pane; the UI toggle is the final say for the current session.

Discoverability

Clicking any of the five letters opens the pane's settings panel directly — the canonical surface for changing toggle state and reading what each toggle does. Each row in the panel renders a Learn more → link to the matching anchor on the per-pane optimizers concept page. VoiceOver names each toggle in literal feature terms ("Filter, on" / "Filter, off") with the toggle's effect on the accessibility hint, so the letter glyph is never the only handle a user has on the control.
