$DSH_HOME/config.yaml was an implicit composition layer: if the file existed,
every launch applied an arbitrary Loader patch graph over the shipped tree,
kept live by a dedicated HMR watcher. Three costs came from the implicitness,
not the capability. A patch replaces its target row's whole config, so a file
written months ago pins that row to the field set it knew and every default
the shipped tree later adds silently stops applying. It competed with the
typed settings namespaces llm-deepseek and llm-pi-ai already register, so
which one wins was a function of layer order rather than meaning. And the
explicit escape hatch it was supposedly redundant with did not exist on every
surface: dsh -p, dsh meta, and dsh upgrade all rejected --config, so for them
the implicit file was the only composition route at all.
Complete the explicit layer first: --config and --config-replace now work on
every booting surface. A headless --config-replace tree must still mount a
webserver row, because that surface reaches its own agent over the same HTTP
gateway the browser uses; AppCLIEntry names that contract in the failure
instead of reporting a bare missing service.
Then delete the implicit one. PERSONAL_CONFIG_FILENAME, loadPersonalPatches,
watchPersonalPatches, and the config-only HMR row mounted for it are gone; a
file left at that path is inert, and --dump-config no longer reads the Harness
home. --config therefore stops *replacing* the personal overlay and simply
*is* the user overlay.
No migration: a user who wants the old behavior names the same file
(dsh --config ~/.dsh/config.yaml), which a shell alias makes permanent.
dsh --dump-config and dsh web --dump-config compose the shipped base,
the surface overlay, and the --config or personal overlay — exactly the
layers that surface boots — and print the entry list as YAML without
booting; --dump-default-config stops at the surface overlay so the two
outputs diff to precisely the user layer's effect.
The dump shares the mounting code: the vendored include exports its
patch algorithm as applyEntryPatches() and its !!js dialect as
entryListSchema (logged in vendor/README.md), dsh-app-boot's
renderConfigDump() composes and renders through both (and now imports
the dialect instead of duplicating it), and the CLI adds a thin
dump-config mode. !!js expressions print verbatim; unmatched patches
warn on stderr; boot-only flags are rejected alongside the dump flags.

Markerless requests pass on any Host (a non-browser sender is the principal
and forges headers anyway); browser Host matching gains port-less entries and
WHATWG normalization; dsh derives LAN IP-literal authorities for an
all-interfaces bind and web grows --trusted-host for named ones.
Integrate the Commander adapter with master's `dsh web --workspace-root`
(workspace-aware session flow).
- args.ts: add `--workspace-root <path>` to the web subcommand; WebInvocation
carries workspaceRoot.
- web.ts: keep the adapter-parsed signature, take (host, port, dev,
workspaceRoot) and pass workspaceRoot through to AppCLIEntry (drop master's
re-added parseArgs and CLI host/port validation — the schema owns those).
- bin.ts forwards invocation.workspaceRoot; args.spec + the Agent Note pair note
the flag.
ds-review-bot: `dsh web -p task`, `dsh web --resume s`, and `dsh --config c.yml
web` reached the web action with those values in program.opts() but the action
ignored them and served — silently dropping mode-specific inputs. The web
action now reads the parent opts and fails loud (exit 1) on a leaked
--config/-p/--resume, matching the root mode's mixing guard. Covered in
args.spec.ts.
Also (ds-review-bot): tui-demo/README documented the removed `dsh
[path-to-cordis.yml]` positional form; corrected to bare `dsh` / `dsh --config
<path>`. Agent Note + Chinese pair note the web-leak guard.
The adapter no longer validates --host/--port or declares the allowed set:
LOOPBACK_HOST/ALL_INTERFACES_HOST leave args.ts. --host/--port are now
unvalidated pass-through overrides — the adapter only Number-coerces the port
string (the dsh-host-webserver schema wants a number). That schema
(host a 127.0.0.1/0.0.0.0 literal union, port a natural <= 65535) is the single
source of both the default (the shipped cordis.yml webserver row) and validity;
AppCLIEntry patches an explicit flag into that row, so a bad host/port fails
loud at the schema on boot (verified: `dsh web --host 9.9.9.9` and `--port abc`
both exit 1 with the schema's ValidationError).
web.ts keeps two display-only literals (the printed loopback URL, the
all-interfaces LAN-detection check), commented as mirrors of the schema, not a
source of truth. Agent Note + Chinese pair and README updated; the args spec
drops the host/port exit-code cases (now the schema's job, covered by the web
smoke on boot).
Drop the bare `dsh <config>` positional in favor of a `--config <path>` flag.
Without a root positional, `web` can be a real Commander subcommand in one
program instead of the reserved-first-token dispatch to a second parser, so
`dsh --help` lists every mode natively (no hand-pasted command text) and the
second parser + reserved-token machinery are gone.
Grammar:
dsh TUI (shipped tree + ~/.dsh overlay)
dsh --config <path> TUI, alternate tree (demos/tests only)
dsh --resume <id> TUI, resume a session
dsh -p "task" headless one-shot
dsh web [--host --port --dev]
`dsh` is the product front door with no positional; `--config` exists only so
demo:cordis, demo:code-mode, and the keyless PTY smokes can point the shipped
bin at an example tree. Those three sites and the /resume re-exec argv move to
`--config <path>`. The `-p` + `--config`/`--resume` mode-mixing guard and the
cordis.yml-owns-host/port-default fix are preserved.
Agent Note + Chinese pair, README, tui.ts docs updated. All 13 PTY smokes
(including code-mode via --config and the exec-replace resume handoff) green.
The merge's "always pass adapter-resolved host/port to AppCLIEntry" made the
adapter's 127.0.0.1/3080 shadow apps/cli/cordis.yml's webserver row — editing
the yml port would have had no effect, a duplicated default.
The adapter now assigns no host/port default: an absent --host/--port leaves the
field undefined (WebInvocation.host?/port?), runWeb forwards each to AppCLIEntry
only when present, and AppCLIEntry patches the webserver row only for an
explicit flag. cordis.yml is the single source of the host/port default; the
adapter still validates a flag when given. Removes the now-unused
DEFAULT_WEB_PORT; LOOPBACK_HOST/ALL_INTERFACES_HOST stay as the allowed-value
vocabulary (validation + the printed URL/LAN line).
Address review and cut ceremony: the adapter no longer models help/version/
errors as DshInvocation members. Commander owns those under exitOverride — it
prints usage or the diagnostic and one try/catch in parseDshArgs turns the
thrown CommanderError into process.exit with the intended code. bin.ts drops its
help/version/error cases; the union is the three real modes.
Domain checks bail via command.error(print + exit 1): --prompt rejects an empty
task or a stray config/--resume, empty --resume= fails loud, and --host/--port
are validated. A repeated --resume or a flag captured as a value is Commander's
standard behavior, left alone (a bad id fails loud downstream). dsh --help
discloses web via addHelpText. Net: args.ts 185 -> 112 lines.
Also fixes review nits: built-bin e2e resolves on `close`; the /resume handoff
uses `dsh --resume=<id> -- <config>` so a config named `web` stays a positional;
and stale prose (cordis.yml comment, app-boot module doc + duplicate JSDoc,
ui/README, two feature notes, an agent-loop test name) tracks the shipped state.
Removes tui-demo's now-dead plugin-include dep and vendor/loader + app-boot
tsconfig references.
Integrate the Commander argument adapter with master's safe session-resume
feature and dsh web --dev flag.
- args.ts: add --dev to the web parser.
- tui.ts: keep master's process.execve in-place resume handoff, but take the
adapter's parsed (config, resume); inject the resume id through boot's
prepare(ctx) hook via ctx.provide(RESUME_SESSION_ID_KEY, id) instead of the
RESUME_SESSION_ID env var; rebuild the re-exec argv as `dsh --resume <id>`.
- app-boot: drop master's replaceResumeArg (no longer needed) alongside the
already-removed parseResumeArg; add RESUME_SESSION_ID_KEY.
- the four tui-agent/cordis configs read the ctx-provided resumeSessionId via a
typeof-guarded !!js expression, so resume needs no env var.
- web.ts: keep master's client roster and --dev watch, take parsed host/port/dev.
Simplify the Commander adapter now that behavior can change: dispatch a leading
`web` token to its own parser instead of a subcommand of the root program, and
read opts()/processedArgs after parse() instead of action closures with a
mutable holder.
This removes enablePositionalOptions(), the parent-option leak guard, both
action closures, and the --resume/--prompt argParser threading. Behavior
changes: `dsh -p x web` is a headless prompt (extra positional dropped),
`dsh web -p x` fails loud (web has no -p), and a repeated --resume is natural
last-wins. The two real fail-loud invariants stay as post-parse checks: an empty
--resume= id (agent-loop treats '' as no-resume) and an empty -p task.
Trims args.spec.ts to the routing/fail-loud/help behavior that matters; the
tui-agent keyless PTY smoke still covers bin.ts dispatch end to end. Net ~114
fewer lines across adapter and tests.
Replace the dsh CLI's three hand-rolled parsing idioms (raw argv[0]/includes
dispatch in bin.ts, per-mode node:util parseArgs in headless.ts/web.ts, and the
bespoke parseResumeArg scanner in dsh-app-boot) with a single Commander adapter
in apps/cli/src/args.ts. parseDshArgs resolves argv into a discriminated
DshInvocation union; bin.ts switches on the mode and dynamic-imports the chosen
module, which now consumes already-parsed values.
- web is a real subcommand; --host uses choices and --port an argParser range
check, moving validation into the parser.
- --resume rejects empty and repeated forms; --prompt rejects empty; a config
positional after --prompt and a root flag placed before web fail loud.
- adds --help/--version; removes parseResumeArg from dsh-app-boot.
- new apps/cli/tests/args.spec.ts (apps/*/tests added to vitest include,
apps/cli/tests to tsconfig.host.json); the tui-agent keyless PTY smoke covers
bin.ts dispatch end to end unchanged.
