New package on the domain data form: one session_projcache record per
session (key → {stateVersion, observedSeq, state}), landing beside
workspace.json under the shipped json backend. Write policy: two mandatory
points (turn/end + session disposal) with count/interval throttling between
them (both Config fields required — flush cadence is a deployment choice);
every background write is fail-soft (log + stay stale, self-heal on the
next write or cold read). coldSnapshot(id) runs the read ladder — cached
rows + persistence readFrom from the registry's anchored restore floor +
registry restore + fail-soft write-back — detecting crash-repair-shrunk
logs via the one-below anchor and degrading to a single full re-read.
Mounted in apps/cli/cordis.yml (writeEveryEvents 200 / writeIntervalMs
5000).

The dsh command-line entry follows the apps/ assembly tier: apps/* are product assemblies over packages/* libraries. Plain dsh boots the interactive TUI coding agent, dsh -p "task" runs one headless turn, and dsh web serves the browser UI.
Argv is parsed once through a Commander adapter (src/args.ts): one program whose default (no subcommand) is the TUI/headless surface (--config, -p/--prompt, --resume) and whose web subcommand is the browser UI. src/bin.ts switches on the resolved mode and dynamic-imports only that mode's module. dsh --help lists every mode and dsh web --help renders the web usage, dsh --version prints this app's version, and an unknown option or a mistyped --resume fails loud (stderr, exit 1) instead of misrouting. dsh web's --host/--port are unvalidated pass-through overrides: the dsh-host-webserver schema is the single source of both the default (the shipped cordis.yml value when a flag is absent) and validity, and rejects a bad value at boot.
The TUI surface:
- boots the shipped default config (
examples/tui-agent/cordis.yml), or the tree named by--config <path>(the demo/test escape for booting an alternate example tree), throughdsh-app-boot; - resumes a persisted session with
dsh --resume <session-id>and, when the Node host exposesprocess.execve, supplies the TUI's in-place handoff host: after selector preflight and current-session flush, the host disposes the app and replaces the process with a normalizeddsh --resume <id>; runtimes without process replacement keep the displayed command fallback. The flag provides the id on the boot context underRESUME_SESSION_ID_KEY(no environment variable), which the shipped config reads through!!js, and a missing or unreadable id fails loud instead of creating a fresh session; - treats the invoking directory as the workspace — sessions, relative paths, and workspace instructions resolve from the cwd;
- tells the agent where its own source lives: after boot it adds a prompt section naming this harness checkout, resolved from the launcher's real path so it holds under a PATH symlink and an arbitrary cwd, so the self-referential
cordistoolset can read and modify it; - applies the personal overlay from
~/.dsh(see app-boot's Personal config):.envfills environment gaps (ambient > project.env> personal.env),config.yamlpatches the booted tree.
The Web and headless surfaces boot one shared composition (cordis.yml): both treat the invoking directory as the default project and Workspace root, create named Workspaces beneath that root unless --workspace-root <path> overrides it, load applicable AGENTS.md/CLAUDE.md instructions into each agent-loop request prefix with a 65,536-byte render budget, and opt into first-message model titles. Headless differs only in listening on an OS-assigned port (parallel dsh -p runs never collide; the stderr-printed URL opens the live session in a browser). Both need the frontend dist and client bundles built (pnpm run build && pnpm run build:web).
DSH_TOOLS_MODE selects the tool presentation mode for the whole Web/headless process: native (the schema default when unset), code (the run_code-only Code Mode wire), or both; any other value fails loud at boot through the dsh-tools config schema. It is a TEMPORARY seam — process-wide because Loader composition is static — and is removed once the web UI owns per-session tool-mode selection; the TUI surface ignores it (its config tree pins its own mode).
Install (developer machine)
Symlink the source-running launcher onto your PATH; it resolves the checkout through its own real path, so code changes apply on the next launch with no build step:
ln -sf "$(pwd)/bin/dsh" ~/.local/bin/dsh
pnpm run dsh runs the same entry from the repo root and forwards arguments directly, for example pnpm run dsh -p "task". The built form (lib/bin.js, via pnpm run build) boots the same config under plain Node.
