The shipped host composition moved: `base.cordis.yml` and `web.cordis.yml`
are the dsh-base and dsh-web-app patch layers now. The gate still opened the
old paths and crashed on ENOENT — a gate that cannot read its inputs proves
nothing, loudly or otherwise.
Retargeting it also surfaced what the move implies for ownership: the web
bundle carries the roster and its browser plugin rows now, so the bundle's own
manifest is what must declare them. The gate's existing bare-plugin check said
so as soon as it could parse the file again.
`code` still carried `bash-env` behind its own `isolate` realm and its own
`tool-subagent-report` row — the two the other three presets had already given
back to the host. It was added a layer above the fix, so the rebase carried it
forward untouched, and the shipped deployment ran a preset whose sessions get
no `DSH_WEB_URL` in their shell and hand every subagent a second `report`
registration on the host registry.
Nothing caught it. A tool-catalog assertion cannot: neither row contributes a
tool. The web lane cannot: no scenario composes `code` beside another preset,
which is when the second `report` throws. The presets are near-copies of one
another, so "fixed in three of four" is the shape this failure takes, and it
will take it again.
So the invariant is checked rather than described. `verify-cordis-config` now
rejects any shipped preset row that is also active on the host plane, which is
the property both defects violated: a row active on both planes is mounted once
per process and once per session, and what that costs depends on the row — a
provider behind an `isolate` realm shadows the host's for its own consumers, so
a host contributor reaches nobody; a row registering into a host singleton
registers once per live session, so the second collides.
Code Mode was a deployment-wide field on the host `tools` row: a
deployment ran every session that way or none. The obvious product
shape — 代码模式 beside 标准/极简/创造 in the preset picker — had
nothing to hang on.
The registry itself cannot move into a preset; the agent loop's
scheduler, the api-proxy's presenters, and every tool plugin are its
consumers. So split the registry from its projection: `presentAs(mode)`
writes one cell on the calling agent's scope layer, exactly as
`restrict()` does, and the three reads that decided presentation take
that scope's mode instead of the service's. The config `mode` becomes
the default agents shadow rather than a process-wide fact.
Two consequences are load-bearing. `run_code` now enters a view only
for scopes whose own mode presents it — a native agent must not find it
dispatchable because another agent in the process does — and the
reserved name holds whatever the configured mode, since any agent may
select a code mode later.
`dsh-agent-tool-mode` is the row a preset carries to declare this. A
code mode waits for the host's `codeRuntime` rather than assuming it,
so a runtime-less deployment fails the preset at mount, naming the
row, instead of at the session's first request.
The shipped `code` preset is `standard` plus that row, ordered second.
A picker showed directory names, so the settings page could only ever list
`standard` / `core-web` / `cordis` and hope the reader knew what they meant.
A preset may now publish display text in an optional `preset.yml` beside
its composition, and the section renders cards — name, description, and the
one in use — instead of rows.
The file carries display text ONLY. `id` is the directory name and `trust`
comes from the root a preset was discovered under, so neither is writable
there: otherwise a locally authored preset could name itself into the
shipped set. It is a separate file because a composition is a top-level list
of plugin rows — YAML cannot carry sibling keys beside it, and a fake
metadata row would hand the Loader something to load.
Every read failure degrades to no metadata; absent, malformed, wrongly
typed, and blank all mean the same thing and the picker falls back to the
id. Presentation is not capability: a preset whose name is broken still
mounts.
The editor gained name and description fields above the YAML, and clearing
both removes the file rather than storing a blank name.
The Agent Note was written when only the seam existed and never caught up.
Rewritten in place, per the implemented-note contract, with the four facts the
later work established:
- a preset file is an INPUT: `EntryTree.write()` persists a tree whenever the
Loader thinks the config changed, and a self-disposing plugin is enough, so
the inherited behaviour truncates a shipped preset to `[]` the first time a
session ends
- a plugin that looks itself up in the global registry breaks inside a preset,
because `register()` files into the calling context's scope — the general
rule behind the `dsh-tool-skill` fix
- an entry-local `isolate` realm is invisible to the agent's own scope too, not
only to the host, which is what makes a preset's registry that agent's own
and also why a consumer left outside the group silently contributes nothing
- switching is blank-only, and why it swaps the subtree rather than the session
`docs/architecture.md` gains an Agent Presets section: the map has to carry a
new architectural concept or it is wrong, and the root layout gains the group.
Both budget ceilings are raised rather than the content cut. `AGENTS.md` sat at
1774/1775 — one word of room, already far under the 5% headroom the standard
asks for — so no group line could be added at all; `architecture.md` was in the
same shape. Raising restores headroom instead of encoding "the map may not grow".
One settings row picking which preset new sessions are composed from.
It is deliberately a new-session preference, not a live switch: a session's
preset is fixed at creation and the host refuses to adopt an existing session
under a different one, so the row says "applies to sessions you start from now
on" rather than implying it can retune a running agent.
Options and the current value come from one `agentPreset.list` call — the
roster already reports which id an unspecified session gets, so the row needs
no settings-schema introspection, unlike the permission row it is modelled on.
The write targets only the namespace's `default` field.
The menu marks `user` rows: a locally authored preset is exactly as privileged
as the plugins it names, and presenting it identically to a shipped one would
hide that.
An empty roster reads as `unavailable` and renders nothing, because composing
no presets is a valid deployment rather than a failure — distinct from a
roster call that failed, which surfaces its message.
- the subagent projection's empty state becomes a serializable null
sentinel (undefined fields vanish in JSON push frames, leaving stale
identities in clients); consumers treat null and a missing key alike,
and cached sentinels defer to the authoritative refold
- the tool catalog generator mounts the projection registry for
list_agents; the shared unavailable-error copy goes catalog-neutral
- the design note's verification section records the new
subagent-diagnostic snapshot honestly, the 2026-07-22 note's test
inventory is rewritten to the current mechanism, and the session-store
error code is documented
A preset is a directory holding one `agent.cordis.yml`. Mounting it under an
agent's scope context during `setup(agentCtx)` gives that one session its own
tools and prompt sections while every other live session keeps its own.
No registry gains a tier. `dsh-tools` and `dsh-system-prompt` already file
registrations into the calling context's scope layer, and entry contexts chain
to the context a subtree was plugged into, so a composition mounted under
`agent.ctx` is that agent's alone and unwinds with it.
The mount audits itself because a directly-plugged subtree is absent from
`ctx.loader.entries()` and no boot audit covers it. It rejects an unscoped
target, a row that never became usable, and a row that published a service into
the root service realm — that last one is process-global rather than
per-session, and its collision with the next session surfaces as an unhandled
rejection `setup` never observes, leaving a half-composed agent that looks
healthy. The package invariant re-checks that rule on every service
notification, since a row publishing from a timer would escape a one-shot audit.
Raises the `packages/README.md` word ceiling from 920 to 980: the group table
must enumerate every group, and the new `preset/` row is necessary content.

The profile rework left references to the old entry modes behind. Renames
the user patch-layer API and its spec file (watchPersonalPatches ->
watchUserPatches, personal-config.spec.ts -> user-patches.spec.ts) and
retargets the prose that still named `config.yaml`, `--config`, raw-config
mode, and surface overlays: repository-plugin and mcp-memory READMEs, the
credentials-local anchor into app-boot, vendor manifest items 12-13, the
vendored include/hmr comments, and install.sh.
Restores the boot-failure guard the rework dropped with raw mode: the
built-bin case now boots `--profile web --patch <invalid>` and asserts the
settled diagnostic and exit 1, so the HMR initial-scan deadlock stays
covered; its orphaned raw fixture is renamed and the unused one deleted.
The superseded personal-config Agent Note and its superseding profile note
are now cross-linked.
A profile manifest and a bundle manifest are different kinds and shared one
flat `dsh` section: `dsh.plugins` listed bundles (not plugins) and `dsh.patch`
declared a bundle's layer. Each kind now names its role — a bundle declares
`dsh.bundle.patch`, a profile declares `dsh.profile.bundles` — so a
package.json states which role it plays and the list name matches its contents.
`DEFAULT_PROFILE_PLUGINS` becomes `DEFAULT_PROFILE_BUNDLES`, and
`DshManifestSection` splits into `DshBundleManifest`/`DshProfileManifest`.
Pre-release: no compatibility shim; turtle-ui moved with it (bd5ff10).
The tool catalog boots every tool with its default config, but
allowParallelInProgress has no default, so the generator has to choose;
the page now says which branch it shows. The Agent Note's sidecar count
went stale twice inside this PR, so it records the refresh rule instead
of a point-in-time census. The SDK builtin entry pins its config literal
with satisfies like every sibling.
Regenerate persistence catalog (types.ts line drift from retired
PreStepContext/RequestFailureContext) and drop the retired PreStepContext
entry from the type-equiv manifest.
- composeProfile keeps layers as bundle/user/overlay+flags segments instead
of one flat list later re-sliced by index arithmetic; the row index drops
the group-walk (profile trees are flat patch compositions) and the double
composition.
- The config dump anchors on the profile's real empty root (written by the
shared prepareProfile) instead of materializing a temp file, so dump and
boot compose over the identical base by construction.
- dsh-base drops its patchPath export: the dsh.patch manifest field is the
one contract; the package carries no runtime API.
- packageDirFromAnchor is paths-probe only (the require.resolve fast path
duplicated the probe's outcome); basename() replaces hand-rolled path
splitting; verify-cordis-config stops re-reading bundle manifests in-loop.
Update every doc referencing base.cordis.yml/web.cordis.yml, --config, -p, or
$DSH_HOME/config.yaml to the profile vocabulary with bilingual counterparts
re-recorded; regenerate the catalogs and graphs; add the
profile-plugin-bundles Agent Note recording the design and its rejected
alternatives.
dsh --profile <name> replaces the fixed entry modes: --config and -p are
removed, --patch adds overlays over the composed profile, a positional task
selects one-shot mode (requires the headless-runner row), and dsh web stays as
the alias for --profile web carrying the Web flag family as patches. dsh
plugin --profile <name> forwards verbatim to pnpm in the profile directory,
initializes on first use, and reconciles the dsh.plugins layer list after
add/remove (patch-less packages warn and stay plain dependencies). Config
dumps and the keyless web e2e scaffold compose the same bundle layers over the
same empty root as the boot.
Profile bundles are npm packages declaring dsh.patch in their manifest:
dsh-base carries the former base.cordis.yml rows as one insert over the empty
profile root; dsh-web-app carries the web overlay plus a runtime glue plugin
owning what used to be launcher code (frontend dist resolution via
frontend-static, the web-surface prompt section, bash runtime variables, the
readiness-gated URL line); dsh-headless carries the one-shot runner driving a
task turn through the in-process API carrier under the launcher-provided
ctx.headlessIo seam.
The webserver's built-in static dist serving becomes a single-owner fallback
seat (registerFallback/applyIndexTaps); the SPA server moves to the new
@deepseek-ai/dsh-frontend-static plugin so the composing application owns its
dist as composition, not carrier config. distIndex leaves the webserver
schema; unclaimed fallback answers 404.
The per-file 100% thresholds name only the failing file. A custom istanbul
reporter now prints one clickable path:line:col record per uncovered
statement, branch path, and function, right above the threshold errors, in
both the CI coverage lane and local test:coverage runs (they share this
config). CJS because istanbul-reports loads custom reporters with a bare
require() outside the tsx/ESM pipeline.
